Item 1.01 Entry into a Material Definitive Agreement.

Securities Purchase Agreement

On February 1, 2023, Advanced Emissions Solutions, Inc. ("ADES" or the "Company") entered into a Securities Purchase Agreement (the "Purchase Agreement") with Arq Limited, a company incorporated under the laws of Jersey ("Arq"), pursuant to which ADES acquired all of the direct and indirect equity interests of Arq’s subsidiaries (collectively, the "Purchased Interests") in exchange for consideration consisting of (i) 3,814,864 shares of common stock, par value $0.001 per share, of ADES (the "Common Stock"), representing 19.9% of the outstanding shares of Common Stock prior to the completion of the transactions contemplated by the Purchase Agreement, and (ii) 5,294,462 shares of Series A Convertible Preferred Stock, par value $0.001 per share, of ADES (the "Series A Preferred Stock" and the acquisition by ADES of the Purchased Interests, the "Transaction"). In connection with the issuance of the Series A Preferred Stock pursuant to the Purchase Agreement, ADES filed the Certificate of Designations of Preferred Stock for the Series A Preferred Stock (the "Certificate of Designations") with the Secretary of State of the State of Delaware. Capitalized terms used herein but not otherwise defined have the meaning set forth in the Purchase Agreement.

The Purchase Agreement contains customary representations, warranties and covenants. The Transaction closed concurrently with execution of the Purchase Agreement.

The foregoing summary of the Purchase Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Purchase Agreement, which is filed as Exhibit 2.1 to this Form 8-K and incorporated by reference herein.

The Purchase Agreement and the above description have been included to provide investors and security holders with information regarding the terms of the Purchase Agreement. They are not intended to provide any other factual information about ADES, Arq or their respective subsidiaries or affiliates or equityholders. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of those agreements and as of specific dates; were solely for the benefit of the parties to the Purchase Agreement; and may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made by each contracting party to the other for the purposes of allocating contractual risk between them that differ from those applicable to investors. Investors should be aware that the representations, warranties and covenants or any description thereof may not reflect the actual state of facts or condition of ADES or Arq or any of their respective subsidiaries, affiliates, businesses, or equityholders. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures by the Company.

Series A Preferred Stock

Each share of Series A Preferred Stock will be automatically converted into a share of Common Stock upon approval by the holders of the percentage of Common Stock required to approve such conversion under the applicable rules of The Nasdaq Stock Market ("Nasdaq"), without the need for any action on the part of the holders of the Series A Preferred Stock (the "Conversion Approval"). Each share of Series A Preferred Stock is deemed to have an original issue price of $4.00 per share (the "Original Issue Amount"). The number of shares of Common Stock issued upon conversion of each share of Series A Preferred Stock shall be equal to the product of (i) the sum of (A) the Original Issue Amount plus (B) an amount equal to the cumulative amount of the accrued and unpaid dividends on such share at such time (regardless of whether or not declared or funds for their payment are lawfully available) divided by (ii) the Original Issue Amount, subject to adjustment as provided in the Certificate of Designations.

Holders of the Series A Preferred Stock are entitled to receive cumulative dividends which will accrue quarterly on the last day of each applicable quarter (whether or not declared or funds for their payment are lawfully available) and will be payable quarterly, in arrears, on the earlier to occur of (a) the date any dividend is paid to holders of Common Stock with respect to such quarter and (ii) 30 days after the end of each quarter (the "Series A Quarterly Dividend") at the rate per share of Series A Preferred Stock equal to the greater of (i) if the Company declares a cash dividend on the Common Stock with respect to such quarter, the amount of the cash dividend that would be received by a holder of Common Stock in which such share of Series A Preferred Stock would be convertible on the record date for such cash dividend and (ii) an annual rate (the "Rate") of 8.0% of the Original Issue Amount per annum compounded quarterly (the "Coupon Dividend") with respect to such quarter. The Rate will increase by 2.0% on the first day of the first quarter ending on or after the 635th day following the closing date of the first issuance of Series A Preferred Stock and on each subsequent anniversary of such date.

The Series A Quarterly Dividend is payable in cash or in additional shares of Series A Preferred Stock (the "Series A PIK Shares"), at the option of the Company. The number of Series A PIK Shares to be issued shall be determined by dividing (i) the Series A Quarterly Dividend payable with respect to all shares of Series A Preferred Stock held by a holder thereof by (ii) the

aggregate Original Issue Amount of all shares of Series A Preferred Stock held by a holder thereof, and each fractional Series A PIK Share will be rounded to the nearest whole Series A PIK Share (with 0.5 of a share being rounded down to 0.0).

In the event of the Company’s liquidation, dissolution or winding up, after payment or provision for payment of the Company’s debt and other liabilities, a holder of Series A Preferred Stock will receive a liquidating distribution equal to the amount of the cumulative accrued but unpaid dividends on each share of Series A Preferred Stock held by such holder. After the payment to the holders of Series A Preferred Stock of such liquidation preference, the holders of outstanding shares of Series A Preferred Stock will participate pari passu with the holders of Common Stock on an as-converted basis in any remaining distributions out of the Company’s assets available for distribution to stockholders.

Holders of shares of Series A Preferred Stock will generally have no voting rights. However, the Company is restricted from taking certain actions without the written consent or affirmative vote of the holders of at least a majority of the then outstanding shares of Series A Preferred Stock, including, but not limited to, consummating a merger of the Company with or into another party or a sale of substantially of the Company’s assets, issuing Common Stock or instruments convertible into Common Stock representing more than 20% of the outstanding share capital of the Company to the extent the applicable issuance requires approval of holders of Common Stock pursuant to applicable law or the rules of the applicable stock exchange on which the Common Stock is listed, or authorizing, creating or issuing any Senior Stock or Parity Stock (each as defined in the Certificate of Designations) of the Company (or amending the provisions of any existing class of securities to make such class of securities Senior Stock or Parity Stock). In addition, the Company is restricted from amending the Company’s Certificate of Incorporation or Bylaws in a manner that adversely affects the rights of the Series A Preferred Stock without the written consent or affirmative vote of the holders of at least 75% of the then outstanding shares of Series A Preferred Stock.

If the Conversion Approval has not been obtained, each outstanding share of Series A Preferred Stock will be redeemed by the Company on February 1, 2028 for cash, at a redemption price equal to the sum of (i) the product of (x) 140% and (y) the Original Issue Amount, plus (ii) an amount equal to the cumulative amount of accrued and unpaid dividends on such share of Series A Preferred Stock.

The foregoing summary of the Series A Preferred Stock does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Certificate of Designations, which is filed as Exhibit 3.1 to this Form 8-K and incorporate by reference herein.

Registration Rights Agreement

Pursuant to the terms of the Purchase Agreement, ADES entered into a Registration Rights Agreement (the "Registration Rights Agreement") with Arq and the Subscribers party to the Subscription Agreements described in Item 3.02 of this Form 8-K. The Registration Rights Agreement provides that as promptly as practicable following the closing of the Transaction, but no later than 150 days after the consummation of the Transactions, ADES will file a registration statement registering the resale of the shares of Common Stock received by Arq and the Subscribers in the Transactions (including shares of Common Stock issued upon conversion of the Series A Preferred Stock). ADES will also use commercially reasonable efforts to have such registration statement declared effective as soon as practicable following the filing thereof, but no later than the earlier of (i) the 210th calendar day (or 270th calendar day if the U.S. Securities and Exchange Commission (the "SEC") gives notice that it will review the registration statement) following the filing thereof and (ii) the 10th business day after the date the SEC gives notice that it will not review the registration statement, subject to certain conditions. The Registration Rights Agreement further provides that certain of the investors party thereto will be entitled to customary "piggyback" registration rights.

The foregoing summary of the Registration Rights Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Registration Rights Agreement, which is filed as Exhibit 10.1 to this Form 8-K and incorporated by reference herein.

Loan Agreement

As previously announced in the Company’s Form 8-K filed with the SEC on August 19, 2022 (the "Prior 8-K"), ADES and CF Global Credit, LP ("CF Global") executed a commitment letter pursuant to which CF Global offered to provide a $10.0 million term loan (the "Term Loan") to ADES. The proceeds of the Term Loan are intended to be utilized for the general corporate purposes of ADES and its subsidiaries.

On February 1, 2023 (the "Closing Date"), ADES, as borrower, certain of its subsidiaries, as guarantors, and CF Global, as administrative agent and lender, entered into the Term Loan upon execution of a Term Loan and Security Agreement (the "Loan Agreement"). Capitalized terms used herein but not otherwise defined have the meaning set forth in the Loan Agreement.

The Term Loan has a term of 48 months and bears interest at a rate equal to either (a) Adjusted Term SOFR (subject to a 1.00% floor and a 2.00% cap) plus a margin of 9.00% paid in cash and 5.00% paid in kind or (b) Base Rate (subject to a 2.00% floor and a 3.00% cap) plus a margin of 8.00% paid in cash and 5.00% paid in kind, which interest on the Term Loan in each case shall be payable (or capitalized, in the case of in kind interest) quarterly in arrears.

ADES will be able to prepay the Term Loan at any time subject to the following prepayment premium: (i) prior to the twelve month anniversary of the Closing Date, the Make-Whole Amount (as defined below), (ii) thereafter but prior to the thirty-six month anniversary of the Closing Date, 2.00% of the outstanding principal amount of the Term Loan being repaid or prepaid or (iii) thereafter until the maturity date, 1.00% of the outstanding principal amount of the Term Loan being repaid or prepaid. The "Make-Whole Amount", with respect to any repayment or prepayment, is (i) an amount equal to all required interest payable (except for currently accrued and unpaid interest) on the aggregate principal amount of the Term Loan subject to such prepayment or repayment from the date of such prepayment or repayment through but excluding the date that is the first anniversary of the Closing Date calculated using an interest rate equal to (x) Adjusted Term SOFR for an interest period of one month in effect on the third U.S. Government Securities Business Day prior to such prepayment or repayment plus (y) 14.00% per annum and assuming all interest was paid in cash, plus (ii) a prepayment premium of 2.00% on the aggregate principal amount of the Term Loan subject to such prepayment or repayment.

The Term Loan is secured by substantially all of the assets of ADES and its subsidiaries (including those acquired in the Transaction), subject to customary exceptions.

The Loan Agreement includes, among others, the following covenants: (1) beginning March 31, 2023 and as of the end of each fiscal quarter thereafter, ADES must maintain a minimum cash balance of $5.0 million (including unrestricted cash as well as cash under the control of CF Global); (2) (x) as of December 31, 2023, for the fiscal year then ended, ADES must have a minimum annual revenue, on a consolidated basis, of $70.0 million, (y) as of December 31, 2024, for the fiscal year then ended, ADES must have a minimum annual revenue, on a consolidated basis, of $85.0 million and (z) for any fiscal year thereafter, ADES must have a minimum annual revenue, on a consolidated basis, of $100.0 million; (3) (x) as of December 31, 2024, for the fiscal year then ended, ADES must have a minimum Consolidated EBITDA of $3.0 million and (y) for any fiscal year thereafter, ADES must have a minimum Consolidated EBITDA of $16.0 million; and (4) beginning after the fiscal quarter ending September 30, 2023, during an LTV Trigger Period, ADES must not exceed a loan to value (based on the consolidated total assets of ADES and its subsidiaries) ratio of 0.40:1.00.

In addition, in connection with the Loan Agreement and as consideration for the Term Loan, ADES agreed to issue to CF Global a warrant (the "Warrant") to purchase 325,457 shares of Common Stock (the "Warrant Shares"). The Warrant has an exercise price of $0.01 per share, subject to adjustment as set forth in the Warrant, is exercisable immediately and will expire on February 1, 2030. The terms of the Warrant do not allow for cash exercise, and the Warrant may only be exercised pursuant to the terms thereof.

The Warrant was issued without registration under the Securities Act in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and Rule 506 promulgated under the Securities Act as sales to accredited investors.

The foregoing descriptions of the Loan Agreement and the Warrant do not purport to be complete and are qualified in their entirety by reference, respectively, to the full text of the Loan Agreement, which is filed as Exhibit 10.2 to this Form 8-K, and the Warrant, which is filed as Exhibit 4.1 to this Form 8-K.

Item 1.02 Termination of a Material Definitive Agreement.

In connection with entry into the Purchase Agreement described above in Item 1.01, on February 1, 2023 that certain Transaction Agreement, dated August 19, 2022, by and among Elbert Holdings, Inc., Elbert Merger Sub 1, Inc., Arq and the Company (the "Transaction Agreement") was terminated pursuant to a termination agreement entered into by each of the parties to the Transaction Agreement. The terms of the Transaction Agreement were previously disclosed in the Prior 8-K. The Transaction Agreement would have provided, subject to its terms and conditions, for a business combination of Arq and ADES. By virtue of the termination of the Transaction Agreement, the Transaction Agreement became void and of no further force or effect, with no liability on the part of any party to the Transaction Agreement.

Item 2.01 Completion of Acquisition or Disposition of Assets.

The information contained above under Item 1.01 is hereby incorporated by reference in response to this Item 2.01 of Form 8-K.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information contained above under Item 1.01 as it relates to the Loan Agreement is hereby incorporated by reference to this Item 2.03 of Form 8-K.

Item 3.02 Unregistered Sales of Equity Securities

On February 1, 2023, ADES entered into Subscription Agreements (the "Subscription Agreements") with certain persons (the "Subscribers") pursuant to which the Subscribers subscribed for and purchased shares of Common Stock for an aggregate purchase price of approximately $15.4 million and at a price per share of $4.00 (the "PIPE Price Per Share" and such transaction, the "PIPE Investment"). The securities issued to the Subscribers under the Subscription Agreements were issued pursuant to an exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), Rule 506 of Regulation D, which is promulgated thereunder, and Regulations S of the Securities Act. ADES is relying on this exemption from registration based in part on representations made by each of the Subscribers under the Subscription Agreements.

The sale of the securities pursuant to the Subscription Agreements has not been registered under the Securities Act or any state securities laws. The securities may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. Neither this Form 8-K, nor the exhibits attached hereto, is an offer to sell or the solicitation of an offer to buy the securities described herein.

The information contained above under Item 1.01 as it relates to the Warrant is hereby incorporated by reference to this Item 3.02 of Form 8-K.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On February 1, 2023, the Board of Directors (the "Board") of the Company expanded the size of the Board from four to seven members and elected Julian McIntyre, Richard Campbell-Breeden and Jeremy Blank to the newly created vacancies on the Board, effective immediately. Each of Mr. McIntyre, Mr. Campbell-Breeden and Mr. Blank will serve as a director until the Company’s next annual meeting of stockholders and thereafter until a successor is duly elected and qualified. Neither Mr. McIntyre, Mr. Campbell-Breeden nor Mr. Blank will initially serve on any committee of the Board.

Messrs. McIntyre, Campbell-Breeden and Blank will each receive compensation for service as a non-management director of the Company consistent with the compensation generally provided to other non-management directors, as determined by the Board from time to time. Compensation for the Company’s non-management directors is described in the Company’s definitive proxy statement filed with the SEC on March 29, 2022.

Messrs. McIntyre, Campbell-Breeden and Blank were nominated to the Board pursuant to the terms of the Purchase Agreement, whereby the Company agreed to increase the size of the Board to seven directors and appoint Messrs. McIntyre, Campbell-Breeden and Blank to the Board.

Mr. Blank is the general partner of the indirect parent of CF Global, and his equity interest in CF Global will entitle Mr. Blank to receive up to 10% of the earnings through CF Global on the Term Loan.

Each of Mr. Campbell-Breeden and Mr. McIntyre does not have a direct or indirect material interest in any transaction required to be disclosed pursuant to Item 404(a) of Regulation S-K.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

representation is made under this Section 2.9 with respect to any intellectual property or intellectual property rights, which are the subject of Section 2.11.

2.10Real Property; Leasehold. Neither Arq nor its Subsidiaries own nor have ever owned any real property.

To the Knowledge of Arq, there is no existing material default under any Arq Real Estate Lease by any party thereto and no event has occurred or circumstance exists which, with the delivery of notice, the passage of time or both, would constitute such a breach or default, or permit the termination, modification or acceleration of rent under such Arq Real Estate Lease.

The applicable Arq Subsidiary’s possession and quiet enjoyment of the leased real property under each Arq Real Estate Lease has not been disturbed, and to the Knowledge of Arq, there are no material disputes with respect to any Arq Real Estate Lease. Neither Arq nor its Subsidiaries have collaterally assigned or granted any other security interest in any Arq Real Estate Lease or any interest therein that would reasonably be expected to be, individually or in the aggregate, material to Arq and its Subsidiaries, taken as a whole.

2.11Intellectual Property.

(a)An Arq Subsidiary, owns, or has the legal and valid right to use, as currently being used by the applicable Arq Subsidiary, all Company IP Rights, and with respect to Company IP Rights that are owned by an Arq Subsidiary, has the right to bring actions for the infringement of such Company IP Rights, in each case except subject to the terms of the license agreements set forth on Section 2.11(c) of the Arq Disclosure Schedule, for any failure to own, have such rights to use, or have such rights to bring actions for infringement that would not reasonably be expected to be material to the Arq Business.

(b)Section 2.11(b) of the Arq Disclosure Schedule sets forth an accurate, true and complete listing of (i) all Company IP Rights that are owned by the Arq Subsidiaries that are registered, filed or issued under the authority of, with or by any Governmental Body, including all Patents, registered Copyrights, and Trademarks (including domain names) and all applications for any of the foregoing, (ii) all Company IP Rights that are exclusively licensed to an Arq Subsidiary that are registered, filed or issued under the authority of, with or by any Governmental Body, including all Patents, registered Copyrights, and Trademarks (including domain names) and (iii) all applications for any of the foregoing, and, specifying as to each such item, as applicable, the owner(s) of record (and, in the case of domain names, the registrar), jurisdiction number, date, and status of the mark, application and/or registration. Each item of Company IP Rights that is Company Registered IP is and at all times has been filed and maintained in compliance with all applicable Law and all filings, payments, and other actions required to be made or taken to maintain such item of Company Registered IP in full force and effect have been made by the applicable deadline. Arq does not own or have any interest in any Company IP Rights.

-9-

(c)Section 2.11(c) of the Arq Disclosure Schedule accurately identifies (i) all material Contracts pursuant to which Company IP Rights are licensed to an Arq Subsidiary (other than (A) any non-customized software that (1) is so licensed solely in executable or object code form pursuant to a non-exclusive, internal use software license and other Intellectual Property associated with such software and (2) is not incorporated into, or material to the development, manufacturing, or distribution of, an Arq Subsidiary’s products or services, (B) any Intellectual Property licensed ancillary to the purchase or use of equipment, reagents or other materials and (C) any confidential information provided under confidentiality agreements), and (ii) whether the license or licenses granted to the applicable Arq Subsidiary are exclusive or non-exclusive. For purposes of greater certainty, the term “license” in this Section 2.11(c) and in Section 2.11(d) includes any license, sublicense, covenant, non-assert, consent, release or waiver.

(d)Section 2.11(d) of the Arq Disclosure Schedule accurately identifies each material Contract pursuant to which Arq or any of its Subsidiaries has granted any license under, or any right (whether or not currently exercisable) or interest in, any Company IP Rights to any Person.

(e)Except as set forth in Section 2.11(d) of the Arq Disclosure Schedule, neither Arq nor any of its Subsidiaries is bound by, and no Company IP Rights are subject to, any Contract containing any covenant or other provision, or any judicial, administrative or arbitral order, judgment, award, order, decree, injunction, settlement or stipulation, that in any way limits or restricts the ability of any Arq Subsidiary to use, exploit, assert, enforce, sell, transfer or dispose of any such Company IP Rights anywhere in the world, in each case, in a manner that would materially limit the business of the Arq Subsidiaries as currently conducted or planned to be conducted.

(f)An Arq Subsidiary is the sole and unrestricted legal and beneficial owner of all right, title, and interest to and in Company IP Rights (other than (i) Company IP Rights exclusively and non-exclusively licensed to an Arq Subsidiary, as identified in Section 2.11(c) of the Arq Disclosure Schedule, (ii) any non-customized software that (A) is licensed to an Arq Subsidiary solely in executable or object code form pursuant to a non-exclusive, internal use software license and other Intellectual Property associated with such software and (B) is not incorporated into, or material to the development, manufacturing, or distribution of, an Arq Subsidiary’s products or services and (iii) any Intellectual Property licensed ancillary to the purchase or use of equipment, reagents or other materials), in each case, free and clear of any Encumbrances (other than Permitted Encumbrances).

3.6Financial Statements.

(a)The audited consolidated financial statements of ADES (including any related notes thereto) included in ADES’ Annual Report on Form 10-K for the fiscal year ended December 31, 2021 filed with the SEC have been prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto) and fairly present in all material respects the consolidated financial position of ADES and its Subsidiaries at the respective dates thereof and the results of their operations and cash flows for the periods indicated. The unaudited consolidated financial statements of ADES (including any related notes thereto) included in ADES’ Quarterly Reports on Form 10-Q filed with the SEC since December 31, 2021 have been prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto or may be permitted by the SEC under the Exchange Act) and fairly present in all material respects the consolidated financial position of ADES and its Subsidiaries as

-23-

of the respective dates thereof and the results of their operations and cash flows for the periods indicated (subject to normal period-end adjustments). Except for obligations or liabilities incurred in the Ordinary Course of Business since the date of the ADES Most Recent Balance Sheet, ADES has no liabilities, secured or unsecured (whether absolute, accrued, known or unknown, contingent or otherwise, and whether due or to become due) that are not fully reflected or provided for on the ADES Most Recent Balance Sheet. Since the date of the ADES Most Recent Balance Sheet, ADES has not experienced any ADES Material Adverse Effect.

(b)Other than as expressly disclosed in Section 3.6(b) of the ADES Disclosure Schedule, since the date of the ADES Most Recent Balance Sheet through the date of this Agreement, there has been no material change in ADES’ or its Subsidiaries’ accounting methods or principles that would be required to be disclosed in the ADES’ Financial Statements in accordance with GAAP. Except as have been described in the ADES Financial Statements, there are no unconsolidated Subsidiaries of ADES or any off-balance sheet arrangements of the type required to be disclosed pursuant to Item 303(a)(4) of Regulation S-K promulgated by the SEC.

(c)ADES has established and maintained, at all times since January 1, 2021, a system of internal control over financial reporting as required by Rule 13a-15 or Rule 15d-15 under the Exchange Act sufficient to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Such internal controls include policies and procedures that are designed to (i) ensure the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of ADES, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of ADES are being made only in accordance with authorizations of management and directors of ADES and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of ADES’ assets that could have a material effect on its financial statements. ADES has disclosed, based on its most recent evaluation of internal controls prior to the date of this Agreement, to the ADES’ auditors and audit committee, (i) any significant deficiencies or material weaknesses in the system of internal control over financial reporting used by ADES and its Subsidiaries, which are reasonably likely to adversely affect ADES’ ability to record, process, summarize and report financial information, (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the preparation of financial statements or the internal control over financial reporting utilized by the ADES and its Subsidiaries, and (iii) any claim or allegation regarding any of the foregoing. ADES’ management has completed an assessment of the effectiveness of ADES’ internal control over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act for the fiscal year ended December 31, 2021, and such assessment is described in the ADES Form 10-K for the year ended December 31, 2021. Neither ADES nor its principal executive officer or principal financial officer has received notice from any Governmental Body challenging or questioning the accuracy, completeness, form or manner of filing of such certifications as of the date of this Agreement.

(d)ADES maintains disclosure controls and procedures as required by Rule 13a-15 or Rule 15d-15 under the Exchange Act. ADES’ disclosure controls and procedures are reasonably effective to ensure that all material information relating to ADES required to be disclosed in ADES’ periodic reports under the Exchange Act is made known to the ADES’ principal executive officer and its principal financial officer by others within ADES, and such disclosure controls and procedures are effective in timely alerting ADES’ principal executive officer and its principal financial officer to such information required to be included in ADES’ periodic reports required under the Exchange Act.

Neither ADES nor its Subsidiaries have collaterally assigned or granted any other security interest in any ADES Real Estate Lease.

3.11Intellectual Property.

(a)ADES, directly or through any of its Subsidiaries, owns, or has the legal and valid right to use, as currently being used by ADES or its Subsidiaries, all ADES IP Rights, subject to the terms of the license agreements set forth on Section 3.11(a) of the ADES Disclosure Schedule, except for any failure to own or have such rights to use as would not reasonably be expected to be material to the business of ADES or its Subsidiaries, as such businesses have been conducted.

(b)Section 3.11(b) of the ADES Disclosure Schedule sets forth an accurate, true and complete listing of (i) all ADES IP Rights that are owned by ADES or its Subsidiaries that are registered, filed or issued under the authority of, with or by any Governmental Body, including all Patents, registered Copyrights, and Trademarks (including domain names) and all applications for any of the foregoing, (ii) all ADES IP Rights that are exclusively licensed to ADES and its Subsidiaries that are registered, filed or issued under the authority of, with or by any Governmental Body, including all Patents, registered Copyrights, and Trademarks (including domain names) and (iii) all applications for any of the foregoing, and, specifying as to each such item, as applicable, the owner(s) of record (and, in the case of domain names, the registrar), jurisdiction number, date, and status of the mark, application and/or registration.

5.8Cooperation. Each Party agrees to cooperate fully with the other Party and to execute and deliver such further documents, certificates, agreements and instruments and to take such other actions as may be reasonably requested by the other Party to evidence or reflect the Contemplated Transactions and to carry out the intent and purposes of this Agreement.

5.9Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the Parties agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

5.10Other Remedies; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any Party does not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder to consummate this Agreement) in accordance with its specified terms or otherwise breaches such provisions. Accordingly, the Parties acknowledge and agree that the Parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity. Any Party seeking an injunction or injunctions to prevent breaches of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

5.11No Third Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the Parties and the D&O Indemnified Parties to the extent of their respective rights pursuant to Section 4.3) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement; provided, however, that the Debt Financing Sources shall be intended third-party beneficiaries of, and may enforce Section 5.1, Section 5.3, Section 5.4, Section 5.5 and Section 5.10.

5.12No Recourse. This Agreement may only be enforced against, and any claims or causes of action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement may only be made against the entities that are expressly identified as Parties hereto.

SERIES A CONVERTIBLE PREFERRED STOCK

(Par Value $0.001 Per Share)

Advanced Emissions Solutions, Inc. (the “Corporation”), a corporation organized and existing under and by virtue of the provisions of the General Corporation Law of the State of Delaware (the “General Corporation Law”), hereby certifies that, pursuant to the authority expressly granted to and vested in the Board of Directors of the Corporation (the “Board of Directors”) by the Second Amended and Restated Certificate of Incorporation of the Corporation (as so amended and as further amended from time to time in accordance with its terms and the General Corporation Law, the “Certificate of Incorporation”), which authorizes the Board of Directors, by resolution, to set forth the designation, rights, powers and preferences, and the qualifications, limitations and restrictions thereof, in one or more series of up to 50,000,000 shares of preferred stock, par value $0.001 per share (the “Preferred Stock”), and in accordance with the provisions of Section 151 of the General Corporation Law, the Board of Directors duly adopted on February 1, 2023 the following resolution:

RESOLVED, that, pursuant to the authority expressly granted to and vested in the Board of Directors by the provisions of Article IV of the Certificate of Incorporation of the Corporation and in accordance with the provisions of Section 151 of the General Corporation Law, the Board of Directors hereby creates and provides for the issuance of a series of Preferred Stock, herein designated as the Series A Convertible Preferred Stock, which shall consist initially of 8,900,000 shares of Preferred Stock (subject to increase or decrease as described herein in accordance with Section 151(g) of the General Corporation Law), and the designations, powers, preferences and relative, participating, optional or other special rights, and the qualifications, limitations or restrictions thereof, of the shares of such series (in addition to the designations, powers, preferences and relative, participating, optional or other special rights, and the qualifications, limitations or restrictions thereof, set forth in the Certificate of Incorporation that are applicable to Preferred Stock of all series) are hereby fixed as follows:

1.Designation of Shares.

(a)The shares of such series shall be designated the Series A Convertible Preferred Stock (hereinafter referred to as the “Series A Preferred Stock”).

(b)Each share of Series A Preferred Stock shall be identical in all respects with the other shares of Series A Preferred Stock.

(c)The authorized number of shares of Series A Preferred Stock shall initially be 8,900,000, which number may from time to time be increased or decreased by resolution of the Board of Directors as permitted by the General Corporation Law.

(d)Each share of Series A Preferred Stock shall be deemed to have an original issue price of $4.00 per share (the “Original Issue Amount”).

(e)For purposes of this Certificate of Designations “Capital Stock” of any person means any and all shares, interests, participations or other equivalents however designated of corporate stock or other equity participations of such person and any rights (other than debt securities convertible or exchangeable into an equity interest), warrants or options to acquire an equity interest in such person.

(f)The Series A Preferred Stock shall, with respect to dividend rights and rights upon liquidation, winding-up or dissolution, rank:

(i)(1) with respect to dividend rights, senior to the Common Stock, par value $0.001 per share of the Corporation (“Common Stock”), and (2) with respect to all other rights, including rights upon liquidation, winding-up or dissolution (other than rights to receive accrued and unpaid dividends on the Series A Preferred Stock in connection with any liquidation, winding-up or dissolution), on parity with the Common Stock;

(ii)senior to any other class or series of Capital Stock of the Corporation, the terms of which provide that such other class or series ranks junior to the Series A Preferred Stock as to dividend rights and/or rights on liquidation, winding-up and dissolution of the Corporation (collectively, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, the “Junior Stock”);

(iii)on a parity with any class or series of Capital Stock of the Corporation the terms of which provide that such class or series ranks on a parity with the Series A Preferred Stock as to dividend rights and/or rights on liquidation, winding-up and dissolution of the Corporation (collectively, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, but excluding any Common Stock, the “Parity Stock”); and

(iv)junior to each class or series of Capital Stock of the Corporation (other than Common Stock) the terms of which do not expressly provide that such class or series ranks junior to or on a parity with the Series A Preferred Stock as to dividend rights and/or rights on liquidation, winding-up and dissolution of the Corporation (collectively, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, the “Senior Stock”).

2.Dividends.

(a)The Series A Preferred Stock shall be entitled to receive, and the Corporation shall pay, as a mandatory dividend, to the full extent of funds lawfully available therefor, dividends which shall be cumulative, and will accrue quarterly on the last day of each applicable quarter (whether or not declared or funds for their payment are lawfully available) and be payable quarterly, in arrears, on the last day of each quarter (the “Series A Quarterly Dividend”) at the rate per share of Series A Preferred Stock equal to the greater of (i) if the Corporation declares a cash dividend on the Common Stock with respect to such Quarter (as defined below), the amount of the cash dividend that would be received by a holder of the Common Stock into which such share of Series A Preferred Stock would be convertible in accordance with Section 3 below on the record date for such cash dividend (the “Common Dividend”) and (ii) an annual rate (the “Rate”) of 8.0% of the Original Issue Amount per share of Series A Preferred Stock per annum compounded quarterly (the “Coupon Dividend”) with respect to such Quarter. The Rate shall increase by 2.0% on the first day of the first Quarter ending on or after the 635th day following the Issuance Date (the “Initial Rate Increase Date”) and on each subsequent anniversary of the Initial Rate Increase Date. The Series A Quarterly Dividend shall be paid each fiscal quarter of the Corporation (including, with respect to the first fiscal quarter of the Corporation after the closing date of the first issuance of any shares of the Series A Preferred Stock (the “Issuance Date”), regardless of when the Issuance Date occurs within such fiscal quarter) (a “Quarter”), in arrears, on the earlier to occur of (i) the date any dividend is paid to holders of Common Stock with respect to such Quarter and (ii) 30 days after

2

the end of each Quarter (each such payment date, a “Series A Dividend Payment Date”), to the holders of record of the Series A Preferred Stock as they appear on the Corporation’s stock register at the close of business on the relevant record date established by the Board of Directors of the Corporation with respect to each such Series A Quarterly Dividend. The Coupon Dividend for the first Quarter during which a share of Series A Preferred Stock is issued shall accumulate from the original date of issuance of such share of Series A Preferred Stock and the holders thereof shall be entitled to a pro rata distribution for such quarter. The holders of Series A Preferred Stock at the close of business on a relevant record date shall be entitled to receive the Series A Quarterly Dividend on the corresponding Series A Dividend Payment Date notwithstanding the conversion of such Series A Preferred Stock following that dividend record date.

(b)The Series A Quarterly Dividend shall be payable in cash or in additional shares of Series A Preferred Stock (the “Series A PIK Shares”), at the option of the Corporation. In the event and to the extent that dividends shall be paid in Series A PIK Shares, the number of Series A PIK Shares to be issued to each holder of Series A Preferred Stock on each Series A Dividend Payment Date as to the shares of Series A Preferred Stock outstanding as of such date shall be determined by dividing (i) the Series A Quarterly Dividend payable with respect to all shares of Series A Preferred Stock held by a holder thereof by (ii) the aggregate Original Issue Amount of all shares of Series A Preferred Stock held by such holder (such price, the “Series A PIK Price”), and each fractional Series A PIK Share payable to any holder shall be rounded to the nearest whole Series A PIK Share (with 0.5 of a share being rounded down to 0.0).

(c)In any case where any dividend payment date shall not be a Business Day, then (notwithstanding any other provision of this Certificate of Designations) payment of dividends need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the dividend payment date; provided, however, that, in such circumstance, no interest shall accrue on such amount of dividends for the period from and after such dividend payment date, as the case may be. For the purposes of this Certificate of Designations, “Business Day” shall mean each day that is not a Saturday, Sunday or other day on which banking institutions in Greenwood Village, Colorado are authorized or required by law to close.

(d)For the avoidance of doubt, no Coupon Dividends will accrue with respect to a quarter if the Conversion Date (as defined below) occurs prior to the last day of such quarter.

(e)So long as shares of Series A Preferred Stock remain outstanding, the Corporation shall not (i) repurchase any shares of Common Stock, Junior Stock or Parity Stock or (ii) declare or pay any dividends on the Common Stock, Junior Stock or Parity Stock with respect to a Quarter unless or until the Corporation has declared and paid (or concurrently declares and pays) in cash all cumulative dividends that would accrue with respect to the Series A Preferred Stock through the end of such Quarter; provided that in no event shall any such dividends per share of Common Stock for any such Quarter exceed the Coupon Dividend per share of Series A Preferred Stock for such Quarter.

3

3.Conversion.

(a)Each share of Series A Preferred Stock (including any Series A PIK Shares) shall automatically convert into Common Stock upon approval by the holders of the percentage of Common Stock required to approve such conversion under the applicable rules of The NASDAQ Stock Market (the “Conversion Approval” and the date of the Conversion Approval, the “Conversion Date”) and without the need for any action on the part of the holders of the Series A Preferred Stock. The Common Stock issued upon such conversion will be registered in the name of the holder of such Series A Preferred Stock, and, if applicable, a certificate for such shares and the cash due upon such conversion will be delivered to, the holders of such Series A Preferred Stock as of the Close of Business on the fifth Business Day following the Conversion Date. Any Common Stock delivered as a result of conversion pursuant to this Section 3 shall be validly issued, fully paid and non-assessable, free and clear of any liens, claims, rights or encumbrances other than those arising under the General Corporation Law or the Bylaws of the Corporation (the “Bylaws”). The number of shares of Common Stock issued upon conversion of each share of Series A Preferred Stock as of any date shall be an amount equal to the product of (i) the sum of (A) the Original Issue Amount for such share of Series A Preferred Stock plus (B) an amount (the “Accrued Amount”) equal to the cumulative amount of the accrued and unpaid dividends on such share at such time (regardless of whether or not declared or funds for their payment are lawfully available) divided by (ii) the Original Issue Amount for such share of Series A Preferred Stock, subject to adjustment as provided herein (the “Series A Conversion Rate”). Not more than five (5) Business Days following Conversion Approval, the Corporation shall deliver a Conversion Notice (defined in subsection (i) below) to each holder of Series A Preferred Stock. Immediately following any conversion, the rights of the holders of converted Series A Preferred Stock, including, without limitation, any accrual of dividends, shall cease and the persons entitled to receive Common Stock upon the conversion of Series A Preferred Stock shall be treated for all purposes as having become the owners of such Common Stock. Concurrently with such conversion, the Series A Preferred Stock shall cease to be outstanding, shall be canceled and the shares of Preferred Stock formerly designated pursuant to this Certificate of Designations shall be restored to authorized but unissued shares of Preferred Stock.

(b)Distributions, Combinations, Subdivisions and Reclassifications by the Corporation. If, after the Issuance Date and prior to the Conversion Date, the Corporation (i) makes a non-cash distribution on its Common Stock, (ii) subdivides or splits its outstanding Common Stock into a greater number of Common Stock, (iii) combines or reclassifies its Common Stock into a smaller number of Common Stock, or (iv) issues by reclassification of its Common Stock any securities (including any reclassification in connection with a merger, consolidation or business combination in which the Corporation is the surviving person), then the Series A Conversion Rate in effect at the time of the record date for such distribution or of the effective date of such subdivision, split, combination, or reclassification shall be proportionately adjusted so that the conversion of the Series A Preferred Stock after such time shall entitle the holder to receive the aggregate number of shares of Common Stock (or shares of any securities into which such shares of Common Stock would have been combined, consolidated, merged or reclassified pursuant to clauses (iii) and (iv) above) that such holder would have been entitled to receive if the Series A Preferred Stock had been converted into Common Stock immediately prior to such record date or effective date, as the case may be, and in the case of a merger, consolidation or business combination in which the Corporation is the surviving person, the Corporation shall provide effective provisions to ensure that the provisions in this Certificate of Designations relating to the Series A Preferred Stock shall not be abridged or amended and, subject to Section 3(c), that the Series A Preferred Stock shall thereafter retain the same preferences, limitations and relative rights, that the Series A Preferred Stock had immediately prior to such transaction or event. An adjustment made pursuant to this Section 3(b) shall become effective immediately after the record date in the case of a distribution and shall become effective immediately after the effective date in the case of a subdivision,

4

combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the Corporation is the surviving person) or split. Such adjustment shall be made successively whenever any event described above shall occur.

(c)Other Extraordinary Transactions Affecting the Corporation. Upon the consummation of any recapitalization, reorganization, consolidation, sale of all or substantially all of the assets of the Corporation and its subsidiaries, taken as a whole, spin-off or other business combination (not otherwise addressed in Section 3(b) above) (a “Corporation Event”), each holder of Series A Preferred Stock shall receive any securities, cash or other assets (if any) that would be paid in respect of the shares of Common Stock into which such shares (or applicable fraction thereof) of Series A Preferred Stock would be convertible at such time if the Conversion Approval had occurred immediately prior to such Corporation Event.

(d)Notwithstanding any of the other provisions of this Section 3, any adjustment by the Corporation shall be made in such a manner as to preserve the economic interests of the holders of the Series A Preferred Stock, and no adjustment shall be made to the Series A Conversion Rate pursuant to Section 3(b) as a result of any of the following:

(i)the grant of Common Stock or options, warrants or rights to purchase Common Stock to employees, officers or directors of the Corporation or its subsidiaries, pursuant to compensation plans and agreements approved by the Board of Directors;

(ii)the issuance of any Common Stock as all or part of the consideration to effect (A) the closing of any acquisition by the Corporation of assets of a third party in an arm’s-length transaction or (B) the consummation of a merger, consolidation or other business combination of the Corporation with another entity in which the Corporation survives and Common Stock remain outstanding to the extent such transaction(s) is or are validly approved by the vote or consent of the Board of Directors; and

(iii)the issuance of securities for which an adjustment is made under another provision of this Section 3.

(e)Upon any adjustment pursuant to this Section 3, the Corporation promptly shall deliver to each holder of Series A Preferred Stock a certificate signed by an appropriate officer of the Corporation, setting forth in reasonable detail the event requiring the adjustment and the method by which such adjustment was calculated and specifying the increased or decreased Series A Conversion Rate then in effect following such adjustment.

(f)The holder of the Series A Preferred Stock shall pay any and all issue, documentary, stamp and other taxes, including any income, franchise, property or similar taxes, that may be payable in respect of any issue or delivery of Common Stock on conversion of, or payment of distributions on, Series A Preferred Stock pursuant hereto and any tax that is due because Common Stock issuable upon conversion thereof or distribution payment thereon is issued in a name other than such holder’s name.

(g)No fractional Common Stock shall be issued upon the conversion of any Series A Preferred Stock. All Common Stock (including fractions thereof) issuable upon conversion of more than one share of Series A Preferred Stock held by a holder thereof shall be aggregated for purposes of determining whether the conversion would result in the issuance of any fractional stock. If, after the aforementioned aggregation, the conversion would result in the issuance of a fraction of a share of Common Stock to the applicable holder, the Corporation shall not issue a fractional share of Common Stock to such holder but shall round the fractional Common Stock to the nearest whole share of Common Stock (with 0.5 of a share being rounded down to 0.0).

5

(h)The Corporation agrees that it will act in good faith to make any adjustment(s) required by this Section 3 equitably and in such a manner as to afford the holders of Series A Preferred Stock the benefits of the provisions hereof, and will not take any action to deprive such holders of the benefit hereof.

(i)Conversion Notice. Promptly upon the occurrence of a conversion under this Section 3, the Corporation shall send to each holder of Series A Preferred Stock a written notice of such conversion (a “Conversion Notice”) which must state:

(i)the occurrence of the conversion of the Series A Preferred Stock;

(ii)the Series A Conversion Rate in effect on the Conversion Date for such conversion; and

(iii)the amount of accumulated and unpaid regular dividends (whether or not declared) as of the Conversion Date.

4.Liquidation.

(a)Prior to conversion pursuant to Section 3, in the event of a liquidation (complete or partial), dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary (a “Liquidation”), after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of Series A Preferred Stock shall be entitled to receive, in respect of any shares of Series A Preferred Stock held by them, out of assets of the Corporation available for distribution to stockholders of the Corporation or their assignees, and subject to the rights of any outstanding shares of Senior Stock and before any amount shall be distributed among the holders of Junior Stock, a liquidating distribution in an amount equal to the amount of the cumulative accrued but unpaid dividends (regardless of whether or not declared or funds for their payment are lawfully available) on each share of Series A Preferred Stock held by such holder (the “Liquidation Preference”); provided at the election of the holder of a share of Series A Preferred Stock, the amount of the Liquidation Preference may in lieu of being paid pursuant to this paragraph (a) instead be treated as Accrued Amount for purposes of determining the amount payable to such holder with respect to such share of Series A Preferred Stock on as-converted basis pursuant to paragraph (b) below.

(b)After the payment in cash or proceeds to the holders of shares of the Series A Preferred Stock of the full amount of the Liquidation Preference with respect to outstanding shares of Series A Preferred Stock, the holders of outstanding shares of Series A Preferred Stock shall participate pari passu with the holders of Common Stock on an as-converted basis in any remaining distributions out of assets of the Corporation available for distribution to stockholders of the Corporation or their assignees. Whenever any such distribution shall be paid in property other than cash, the value of such distribution shall be the fair market value of such property as determined in the good faith reasonable discretion of the Board of Directors or liquidating trustee, as the case may be, and shall to the extent reasonably practicable be paid on a pro rata basis to all stockholders (on an as-converted to Common Stock basis).

(c)Any merger or consolidation of the Corporation shall be deemed a liquidation, and therefore subject to the payment requirements of this Section 4, unless determined otherwise by the written consent or affirmative vote of the holders of seventy-five percent (75%) of the then outstanding shares of Series A Preferred Stock.

6

5.Voting.

(a)General. Except as otherwise required by the General Corporation Law or other applicable law or in Section 5(b) below, holders of Series A Preferred Stock shall not be entitled to any vote on matters submitted to the Corporation’s stockholders for approval. In any case in which the holders of the Series A Preferred Stock shall be entitled to vote pursuant to this Certificate of Designations or pursuant to the General Corporation Law or other applicable law, each holder of Series A Preferred Stock entitled to vote with respect to such matter shall be entitled to vote, with respect to each share of such Series A Preferred Stock, the number of votes that equals the number of shares of Common Stock into which such share of Series A Preferred Stock is then convertible.

(b)Protective Provisions. In addition to any vote required by the Certificate of Incorporation or by applicable law, for so long as any of the shares of Series A Preferred Stock shall remain outstanding, the Corporation shall not, either directly or indirectly by amendment, merger, consolidation or otherwise, do any of the following without (in addition to any other vote required by law or the Certificate of Incorporation) the written consent or affirmative vote of the holders of at least a majority (or, in the case of item (i) below, seventy-five percent (75%)) of the then outstanding shares of Series A Preferred Stock, given in writing or by vote at a meeting, consenting or voting (as the case may be), separately as a series, to:

(i)amend, alter or repeal any provision of this Certificate of Designations, the Certificate of Incorporation or the Bylaws in a manner that adversely affects the powers, preferences or rights of the Series A Preferred Stock (provided that for the avoidance of doubt, the authorization, creation or issuance of any Senior Stock or Parity Stock shall not be subject to approval pursuant to this clause (i) and shall be subject to approval pursuant to clause (iv) below);

(ii)consummate a merger or consolidation of the Corporation with or into another party or a sale of all or substantially all of the assets of the Corporation and its subsidiaries, taken as a whole;

(iii)issue Common Stock or instruments convertible into Common Stock representing more than 20% of the outstanding share capital of the Corporation to the extent the applicable issuance requires approval of holders of Common Stock pursuant to applicable law or the rules of the applicable stock exchange on which the Common Stock is listed; or

(iv)authorize, create or issue any Senior Stock or Parity Stock of the Corporation (or amend the provisions of any existing class of securities to make such class of securities Senior Stock or Parity Stock).

If the Corporation shall propose to take any action enumerated above in clauses (i) through (iv) of this Section 5(b) then, and in each such case, the Corporation shall cause to be filed with the transfer agent(s) for the Series A Preferred Stock and shall give notice of such proposed action to each holder of record of the shares of Series A Preferred Stock appearing on the stock books of the Corporation as of the date of such notice at the address of said holder shown therein. Such notice shall specify, inter alia (w) the effective date of such adoption of any alteration, amendment or repeal of any provision of the Certificate of Incorporation or Bylaws; (x) the date on which such merger or sale of assets is to take place; and/or (y) the date on which shares of Capital Stock are to be listed on a securities exchange or trading market, as applicable and (z) the other material terms of such action. Such notice shall be given at least five (5) Business Days prior to the applicable date or effective date specified above.

7

6.Reservation of Common Stock.

(a)The Corporation shall at all times when the Series A Preferred Stock shall be outstanding, reserve and keep available out of its authorized but unissued Common Stock, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of the Series A Preferred Stock (including any Series A PIK Shares) and all dividends accrued thereon (for the avoidance of doubt, taking into account any other obligations of the Corporation to reserve Common Stock upon the conversion, exchange or exercise of other securities of the Corporation).

(b)If any shares of Common Stock to be reserved for the purpose of conversion of the Series A Preferred Stock (including any Series A PIK Shares) or any dividends accrued thereon require registration or listing with or approval of any governmental authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such shares may be validly issued or delivered upon conversion, the Corporation shall, at its sole cost and expense, in good faith and as expeditiously as possible, endeavor to secure such registration, listing or approval, as the case may be.

7.Redemption.

(a)On February 1, 2028 (or if such date is not a Business Day, on the first Business Day following such date) (the “Redemption Effective Date”), the Corporation shall redeem all of shares of Series A Preferred Stock then outstanding, for cash, at a redemption price per share equal to the sum of (i) the product of (x) 140% and (y) the Original Issue Amount plus (ii) an amount equal to the cumulative amount of accrued and unpaid dividends (regardless of whether or not declared) on such share of Series A Preferred Stock (the “Mandatory Redemption”).

(b)The Corporation shall provide notice of a Mandatory Redemption, specifying the time and place of redemption and the redemption price, by first class or registered mail, postage prepaid, return receipt requested, to each holder of record of Series A Preferred Stock at the address for such holder last shown on the records of the transfer agent therefor (or the records of the Corporation, if it serves as its own transfer agent), not less than fifteen (15) Business Days after the Redemption Effective Date. The Corporation shall pay the redemption price as provided in this Section 7 in immediately available funds, except to the extent prohibited by applicable law.

(c)If the funds of the Corporation legally available for payment of the redemption price to the holders of Series A Preferred Stock pursuant to Section 7(a) on any date of payment with respect to the Mandatory Redemption are insufficient to redeem all shares of Series A Preferred Stock on such date, those funds which are legally available will be used to redeem, on a pro rata basis from the holders thereof based on the number of shares of Series A Preferred Stock then held, the maximum possible number of shares of Series A Preferred Stock being redeemed in accordance with Section 7(a). At any time thereafter when additional funds of the Corporation become legally available for the redemption of the Series A Preferred Stock, such funds will be used to redeem the balance of the shares of Series A Preferred Stock which the Corporation was theretofore obligated to redeem as provided in the immediately preceding sentence. Any shares of Series A Preferred Stock which are not redeemed as a result of the circumstances described in this Section 7(c) shall remain outstanding until such shares shall have been redeemed and the redemption price therefor, as applicable, shall have been paid or set aside for payment in full, and for all periods of time from the Redemption Effective Date through the date of such payment (or setting aside) in full the applicate Rate shall be increased by 2.0% per annum.

8

(d)Upon (i) presentation and surrender of the certificate or certificates representing the shares of Series A Preferred Stock being redeemed pursuant to this Section 7 and receipt of the redemption price therefor or (ii) irrevocable deposit in trust by the Corporation for holders of the Series A Preferred Stock being redeemed pursuant to this Section 7 of an amount in cash equal to the redemption price for the shares of Series A Preferred Stock being redeemed on any redemption date, each holder of Series A Preferred Stock will cease to have any rights as a stockholder of the Corporation by reason of the ownership of such redeemed shares of Series A Preferred Stock (except for the right to receive the redemption price therefor upon the surrender of the certificate or certificates representing the redeemed shares if such certificate or certificates have not been surrendered), and such redeemed shares of Series A Preferred Stock will not from and after the date of payment in full of the redemption price therefor be deemed to be outstanding.

8.Certificates.

(a)The Series A Preferred Stock may be evidenced by certificates in such form as the Board of Directors may approve and, subject to the satisfaction of any applicable legal, regulatory and contractual requirements, may be assigned or transferred in a manner identical to the assignment and transfer of other stock; unless and until the Board of Directors determines to assign the responsibility to another person. Any certificates evidencing Series A Preferred Stock shall be separately identified and shall not bear the same CUSIP number as the certificates evidencing Common Stock.

(b)Any certificate(s) representing the Series A Preferred Stock may be imprinted with a legend in substantially the following form:

“THESE CONVERTIBLE PREFERRED SHARES AND COMMON SHARES ISSUABLE ON CONVERSION HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THESE CONVERTIBLE PREFERRED SHARES NOR ANY COMMON SHARES ISSUABLE ON CONVERSION HEREOF NOR ANY INTEREST OR PARTICIPATION HEREIN OR THEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.

9.Waiver.

Any of the rights, powers, preferences and other terms of the Series A Preferred Stock set forth herein may be waived on behalf of all holders of Series A Preferred Stock by the affirmative written consent or vote of the holders of at least a majority of the shares of Series A Preferred Stock then outstanding (unless the consent of the holders of a higher percentage of the shares of Series A Preferred Stock then outstanding is expressly required for a specific action under this Certificate of Designations).

10.No Other Rights.

The shares of Series A Preferred Stock shall not have any powers, designations, preferences or relative, participating, optional, or other special rights, nor shall there be any qualifications, limitations or restrictions or any powers, designations, preferences or rights of such shares, other than as set forth herein or in the Certificate of Incorporation, or as may be provided by law.

9

11.Transfer Restrictions.

Without the prior written consent of the Corporation, the holders of Series A Preferred Stock shall be prohibited from transferring any Series A Preferred Stock (x) to any person that in the reasonable determination of the Board of Directors is a competitor of the Corporation or, (y) for a period of one year following the Issuance Date, to any person who, as a result of such transfer, is or will become a beneficial owner of greater than 4.99% of the issued and outstanding Common Stock (calculated on a fully diluted basis using the treasury stock method) upon conversion of the applicable Series A Preferred Stock, and the Corporation shall not be required to register any such transfer on the Corporation’s transfer books; provided that the limitations in clauses (x) and (y) shall not apply to a transfer to a person that is a stockholder of Arq Ltd. on Issuance Date.

SHARES OF COMMON STOCK

OF

ADVANCED EMISSIONS SOLUTIONS, INC.

No. W-1    February 1, 2023

FOR VALUE RECEIVED, the undersigned, Advanced Emissions Solutions, Inc., a Delaware corporation (together with its successors and assigns, the “Company”), hereby certifies that

CF Global Credit, LP

or its registered assign is entitled to subscribe for and purchase, at the Warrant Exercise Price per share, the Warrant Share Number of duly authorized, validly issued, fully paid and non-assessable shares of Common Stock. This Warrant is issued pursuant to that certain Term Loan and Security Agreement, dated as of February 1, 2023, by and among the Company, certain subsidiaries of the Company, CF Global Credit, LP and the lenders from time to time party thereto (the “Loan Agreement”). Capitalized terms used in this Warrant and not otherwise defined herein shall have the respective meanings specified in Section 7 hereof.

1.Term. The right to subscribe for and purchase Warrant Shares represented hereby shall expire at 5:00 P.M. (New York City time) on February 1, 2030 (such period being the “Term”).

2.Method of Exercise; Payment; Issuance of New Warrant; Transfer and Exchange.

(a)Time of Exercise. The purchase rights represented by this Warrant may be exercised in whole or in part at any time and from time to time during the Term, and (i) in the event that this Warrant has not been exercised in full as of the last Business Day during the Term, the purchase rights represented by this Warrant shall be deemed to be automatically exercised in full by the Holder as of such last Business Day and (ii) in the event that this Warrant has not been exercised in full as of the occurrence of a Change of Control that occurs during the Term, the purchase rights represented by this Warrant shall be deemed to be automatically exercised in full by the Holder immediately prior to such Change of Control.

(b)No Cash Exercise. The Holder may only exercise this Warrant pursuant to Section 2(c).

(c)Net Issue Exercise. The Holder may exercise this Warrant by electing on one or more occasions, at any time prior to the expiration of the Term, to receive Warrant Shares issuable in accordance with this Warrant (or the portion thereof being cancelled) by surrender of this Warrant at the principal office of the Company together with notice of such election, in which event the Company shall issue to the Holder a number of Warrant Shares computed using the following formula:

X =	Y(A-B)
	A

Where:        X = the number of the Warrant Shares to be issued to the Holder.

Y = the number of the Warrant Shares with respect to which the Warrant is exercised.

A = the fair market value of one share of Common Stock on the date of determination.

B = the Warrant Exercise Price (as adjusted to the date of such calculation).

For purposes of this Section 2(c), the fair market value of one share of Common Stock on the date of determination shall mean:

(i)if the Common Stock is publicly traded, the per share fair market value of the Common Stock shall be the closing price of the Common Stock as quoted on the NASDAQ Global Market, or the principal exchange or market on which the Common Stock is listed, on the last trading day ending prior to the date of determination; and

(ii)if the Common Stock is not so publicly traded, the per share fair market value of the Common Stock shall be such fair market value as determined in good faith by the Board of Directors of the Company in reliance on an opinion of a nationally recognized independent investment banking firm retained by the Company for this purpose; provided that Holder shall have a right to receive from the Board of Directors the calculations performed to arrive at such fair market value and a certified resolution of the fair market value from the Board of Directors of the Company.

The date of determination for purposes of this Section 2(c) shall be the date the notice of exercise is delivered by the Holder to the Company.

(d)Issuance of Warrant Shares and New Warrant. In the event of any exercise of the rights represented by this Warrant in accordance with and subject to the terms and conditions hereof, (i) the Warrant Shares so purchased shall be delivered by the Company within (x) one (1) Business Day after such exercise and delivery of this Warrant and the exercise form, if the Holder provides the Company with at least one (1) Business Day prior written notice or (y) two (2) Business Days after such exercise and delivery of this Warrant and the exercise form, if the Holder did not provide the Company with notice in advance of such exercise, via (A) book-entry transfer crediting the account of the Holder through the Company’s transfer agent and registrar for the Common Stock (which as at the issuance of this Warrant is Computershare Trust Company, N.A.) or (B) if requested by the Holder, in the form of certificates in the name of the Holder, and (ii) unless this Warrant has expired, a new Warrant representing the number of Warrant Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder within such time.

2

(e)Transferability of Warrant. The Warrant and Warrant Shares may be freely sold, assigned, disposed of, pledged, hypothecated, encumbered or otherwise transferred (collectively, a “Transfer”), subject to the restrictions set forth in this Section 2(e). Any Transfer of the Warrant and Warrant Shares must be in compliance with the Act and applicable state securities laws and, if requested by the Company, receipt by the Company of an opinion of counsel, reasonably satisfactory to the Company, that such Transfer is in compliance with the Act and applicable state securities laws. Following any Transfer, the Warrant shall at all times remain subject to the terms and restrictions set forth in this Agreement.

(f)Compliance with Securities Laws.

(i)The Holder, by acceptance hereof, acknowledges that this Warrant and the Warrant Shares to be issued upon exercise hereof are being acquired solely for the Holder’s own account, and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any Warrant Shares to be issued upon exercise hereof except pursuant to an effective registration statement, or an exemption from registration, under the Act and any applicable state securities laws.

(ii)Except as provided in paragraph (iii) below, this Warrant and all Warrant Shares issued upon exercise hereof shall be stamped or imprinted with a legend in substantially the following form (which, in the case of Warrant Shares, shall be in the form of an appropriate book entry notation):

THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A REGISTRATION STATEMENT RELATING THERETO IS IN EFFECT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR SUCH LAWS.

(iii)Upon request of the Holder and, if requested by the Company, receipt by the Company of an opinion of counsel reasonably satisfactory to the Company to the effect that such legend is no longer required under the Act and applicable state securities laws, the Company shall promptly cause such legend to be removed from any certificate or other instrument for this Warrant or Warrant Shares to be Transferred in accordance with the terms of this Warrant.

(g)No Fractional Shares or Scrip. No fractional shares or scrip representing fractional Warrant Shares shall be issued upon the exercise of this Warrant. In lieu of any fractional Warrant Share to which the Holder would otherwise be entitled, the Company shall make a cash payment equal to the fair market value of one Warrant Share on the last trading day ending prior to the payment date multiplied by such fraction.

(h)Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount.

3

(i)No Rights of Stockholders. The Holder shall not be entitled to vote or receive dividends or be deemed the holder of Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, or change of stock to no par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise.

(j)Registration of Common Stock. Any Common Stock issuable to Holder upon exercise of this Warrant shall be “Registerable Securities,” as such term is defined in that certain Registration Rights Agreement, dated as of the date hereof, by and among the Company, the Holder and the other parties thereto (the “Registration Rights Agreement”), and entitled to the registration rights provided therein. Notwithstanding anything to the contrary herein, if the Warrant is exercised in connection with the exercise of the Holder’s registration rights in accordance with the Registration Rights Agreement, the Warrant shall not be deemed to have been exercised to the extent that the applicable Warrant Shares are not sold in the applicable offering. The Company will procure, subject to issuance or notice of issuance, the listing of any Warrant Shares issuable upon exercise of this Warrant on the principal stock exchange on which shares of Common Stock are then listed or traded.

3.Certain Representations and Agreements. The Company represents, covenants and agrees:

(a)This Warrant is, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, duly authorized and validly issued.

(b)All Warrant Shares issuable upon the exercise of this Warrant pursuant to the terms hereof shall be, upon issuance, and the Company shall take all such actions as may be necessary or appropriate in order that such Warrant Shares are, validly issued, fully paid and non-assessable, issued without violation of any preemptive or similar rights of any stockholder of the Company, and free from all taxes, liens and charges. The Company further covenants and agrees that during the period within which this Warrant may be exercised, the Company will at all times have authorized and reserved (as unissued or held in treasury) a sufficient number of shares of Common Stock to provide for the exercise in full of this Warrant. The Company will procure, subject to issuance or notice of issuance, the listing of any Warrant Shares issuable upon exercise of this Warrant on the principal stock exchange on which shares of Common Stock are then listed or traded.

(c)The Company shall take all such actions as may be necessary to ensure that all Warrant Shares are issued without violation by the Company of any applicable law or governmental regulation or any requirements of any securities exchange upon which shares of the Company’s capital stock may be listed at the time of such exercise.

4.Adjustments and Other Rights. The Warrant Exercise Price and Warrant Shares issuable upon exercise of this Warrant shall be subject to adjustment from time to time as follows; provided, that no single event shall cause an adjustment under more than one subsection of this Section 4 so as to result in duplication.

4

(a)Stock Splits, Subdivisions, Reclassifications or Combinations. If the Company shall at any time or from time to time (i) declare, order, pay or make a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) split, subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares or (iii) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, the number of Warrant Shares issuable upon exercise of this Warrant at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be proportionately adjusted so that the Holder immediately after such record date or effective date, as the case may be, shall be entitled to purchase the number of shares of Common Stock which such Holder would have owned or been entitled to receive in respect of the shares of Common Stock subject to this Warrant after such date had this Warrant been exercised in full immediately prior to such record date or effective date, as the case may be. In the event of such adjustment, the Warrant Exercise Price in effect at the time of the record date for such dividend or distribution or the effective date of such split, subdivision, combination or reclassification shall be automatically adjusted to the number obtained by dividing (x) the product of (1) the number of Warrant Shares issuable upon the exercise of this Warrant in full before the adjustment determined pursuant to the immediately preceding sentence and (2) the Warrant Exercise Price in effect immediately prior to the record or effective date, as the case may be, for the dividend, distribution, split, subdivision, combination or reclassification giving rise to such adjustment by (y) the new number of Warrant Shares issuable upon exercise of the Warrant in full determined pursuant to the immediately preceding sentence.

(b)Distributions. If the Company pays one or more dividends on the shares of Common Stock with a record date prior to the issuance of any portion of the Warrant Shares issuable upon exercise of this Warrant, then promptly following the subsequent issuance of such Warrant Shares the Company shall pay (without interest) to the holder thereof the amount of such cash or other property that such holder would have received in such dividend if such holder had exercised this Warrant with respect to such Warrant Shares prior to the record date for such dividend.

(c)Business Combinations. In case of any Business Combination or reclassification of Common Stock (in cash or other property (other than Common Stock) (other than a reclassification of Common Stock subject to adjustment pursuant to Section 4(a)), notwithstanding anything to the contrary contained herein, (i) the Company shall notify the Holder in writing of such Business Combination or reclassification as promptly as practicable (but in no event later than five (5) Business Days prior to the effectiveness thereof), and (ii) the Holder’s right to receive Warrant Shares upon exercise of this Warrant shall be converted, effective upon the occurrence of such Business Combination or reclassification, into the right to exercise this Warrant to acquire the number of shares of stock or other securities or property (including cash) that the Common Stock issuable (at the time of such Business Combination or reclassification) upon exercise of this Warrant in full immediately prior to such Business Combination or reclassification would have been entitled to receive upon consummation of such Business Combination or reclassification; and in any such case, if applicable, the provisions set forth herein with respect to the rights and interests thereafter of the Holder shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to the Holder’s right to exercise this Warrant in exchange for any shares of stock or other securities or property pursuant to this paragraph. In determining the kind and amount of stock, securities or the property receivable upon exercise of this Warrant upon and following adjustment pursuant to this paragraph, if the holders of Common Stock have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination, then the Holder shall have the right to make the same election upon exercise of this Warrant with respect to the number of shares of stock or other securities or property which the Holder will receive upon exercise of this Warrant, provided that if the Holder does not make an election the Holder will receive the kind or amount

5

of consideration that non-electing holders of Common Stock receive in such Business Combination.

(d)Certain Repurchases of Common Stock. The Company shall give each Holder notice five (5) Business Days prior to the Effective Date of any Pro Rata Repurchase of Common Stock.

(e)Rounding of Calculations; Minimum Adjustments. All calculations under this Section 4 shall be made to the nearest one-hundredth (1/100th) of a cent or to the nearest one-tenth (1/10th) of a share, as the case may be. No adjustment in the Warrant Exercise Price or the number of Warrant Shares into which this Warrant is exercisable shall be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or 1/10th of a share of Common Stock, or more.

(f)Timing of Issuance of Additional Securities Upon Certain Adjustments. In any case in which (i) the provisions of this Section 4 shall require that an adjustment (the “Subject Adjustment”) shall become effective immediately after a record date (the “Subject Record Date”) for an event and (ii) the Holder exercises this Warrant after the Subject Record Date and before the consummation of such event, the Company may defer until the consummation of such event (1) issuing to such Holder the incrementally additional shares of Common Stock or other property issuable upon such exercise by reason of the Subject Adjustment and (2) paying to such Holder any amount of cash in lieu of a fractional share of Common Stock; provided, that the Company upon request shall promptly deliver to such Holder a due bill or other appropriate instrument evidencing such Holder’s right to receive such additional shares (or other property, as applicable), and such cash, upon (and subject to) the consummation of such event (or completion of such calculation).

(g)Statement Regarding Adjustments. Whenever the Warrant Exercise Price or the Warrant Shares into which this Warrant is exercisable shall be adjusted as provided in this Section 4, the Company shall as promptly as practicable prepare and make available to the Holder a statement showing in reasonable detail the facts requiring such adjustment and the Warrant Exercise Price that shall be in effect and the Warrant Shares into which this Warrant shall be exercisable after such adjustment.

(h)Adjustment Rules. Any adjustments pursuant to this Section 4 shall be made successively whenever an event referred to herein shall occur. If an adjustment in Warrant Exercise Price made hereunder would reduce the Warrant Exercise Price to an amount below par value of the Common Stock, then such adjustment in Warrant Exercise Price made hereunder shall reduce the Warrant Exercise Price to the par value of the Common Stock.

(i)Proceedings Prior to any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 4, the Company shall take such actions as are necessary, which may include obtaining regulatory, stock exchange or stockholder approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable all shares of Common Stock that the Holder is entitled to receive upon exercise of this Warrant pursuant to this Section 4.

6

5.Taxes.

(a)Withholding. The Company and its paying agent shall be entitled to deduct and withhold taxes on all payments and distributions (or deemed distributions) with respect to the Warrant (or upon the exercise thereof) to the extent required by applicable law. To the extent that any amounts are so deducted or withheld, such deducted or withheld amounts shall be treated for all purposes of this Warrant as having been paid to the Person in respect of which such deduction or withholding was made. In the event the Company previously remitted any amounts to a governmental authority on account of taxes required to be deducted or withheld in respect of any payment or distribution (or deemed distribution) with respect to the Warrant or upon the exercise thereof, the Company shall be entitled (i) to offset any such amounts against any amounts otherwise payable in respect of such Warrant, any Warrant Shares otherwise required to be issued upon the exercise of such Warrant or any amounts otherwise payable in respect of Warrant Shares received upon the exercise of such Warrant, or (ii) to require the Person in respect of whom such deduction or withholding was made to reimburse the Company for such amounts (and such Person shall promptly so reimburse the Company upon demand). The Company shall take commercially reasonable steps to minimize or eliminate any withholding or deduction described in this Section 5, including by giving the Person in respect of whom such deduction or withholding may be made an opportunity to provide additional information or to apply for an exemption from, or a reduced rate of, withholding.

(b)Transfer Taxes. The Company shall pay any and all documentary, stamp and similar issue or transfer tax due on (i) the issue of this Warrant and (ii) the issue of Warrant Shares pursuant to the exercise of this Warrant. However, in the case of the exercise of this Warrant, the Company shall not be required to pay any transfer tax that may be payable in respect of the issue or delivery (or any transfer involved in the issue or delivery) of Warrant Shares to a beneficial owner other than the beneficial owner of the Warrant immediately prior to such exercise, and no such issue or delivery shall be made unless and until the person requesting such issue or delivery has paid to the Company the amount of any such transfer tax or has established to the satisfaction of the Company that such transfer tax has been paid or is not payable.

6.Frustration of Purpose. The Company shall not, by amendment of its Certificate of Incorporation or bylaws, or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but shall at all times in good faith cooperate in the carrying out of all the provisions of this Warrant.

7.Definitions. For the purposes of this Warrant, the following terms have the following meanings:

9.Governing Law; Jurisdiction; Specific Performance. This Warrant shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdiction other than those of the State of Delaware.

The parties agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, and agree not to assert that a remedy of monetary damages would provide an adequate remedy or that the parties otherwise have an adequate remedy at law. The parties acknowledge and agree that any party shall not be required to provide any bond or other security in connection with its pursuit of an injunction or injunctions to prevent breaches of this Warrant and to enforce specifically the terms and provisions hereof.

10.Notices.

References to a Person are also to its permitted assigns and successors. When calculating the period of time between which, within which or following which any act is to be done or step taken pursuant to this Warrant, the date that is the reference date in calculating such period shall be excluded (unless otherwise required by law, if the last day of such period is not a Business Day, the period in question shall end on the next succeeding Business Day).

NOW, THEREFORE, in consideration of the mutual promises and covenants set forth herein, and other consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

Section 1.
Definitions

1.1Certain Definitions. In addition to the terms defined elsewhere in this Agreement, as used in this Agreement, the following terms have the respective meanings set forth below:

(a)“Commission” shall mean the Securities and Exchange Commission or any other federal agency at the time administering the Securities Act.

(b)“Exchange Act” shall mean the Securities Exchange Act of 1934, as amended, or any similar successor federal statute and the rules and regulations thereunder, all as the same shall be in effect from time to time.

(c)“Holder” means the record holder of any Registrable Securities that is an Investor or a permitted transferee of an Investor pursuant to Section 3.2.

(d)“Person” shall mean any individual, partnership, corporation, company, association, trust, joint venture, limited liability company, unincorporated organization, entity or division, or any government, governmental department or agency or political subdivision thereof.

(e)“Registrable Securities” shall mean (i) the shares of Common Stock received by the Investors in the Transaction and the PIPE Investment, (ii) the shares of Common Stock issuable upon conversion of the Series A Preferred Stock received by the Investors in the Transaction and (iii) any shares of Common Stock purchased by affiliates of Arq on the open market prior to the filing of the Registration Statement (as such term is defined below) that become “control securities” as such term is used under Rule 144 promulgated under the Securities Act. Any particular Registrable Securities shall cease to be Registrable Securities when (A) a registration statement with respect to the sale of such securities shall have been declared effective under the Securities Act and such securities shall have been disposed of in accordance with such registration statement, (B) such securities shall have been sold to the public pursuant to Rule 144 (or any successor provision) under the Securities Act or (C) such securities shall cease to be outstanding or (D) as to Registrable Securities held by an Arq Shareholder following a transfer permitted by Section 3.2 (other than an Arq Shareholder who is also an Investor), the date on which all Registrable Securities beneficially owned by such Arq Shareholder may be sold in a single sale pursuant to any section of Rule 144 under the Securities Act (or any similar provision then in force under the Securities Act) without any volume limitations.

(h)“Securities Act” shall mean the Securities Act of 1933, as amended, or any similar successor federal statute and the rules and regulations thereunder, all as the same shall be in effect from time to time.

Section 2.
Resale Registration Rights

2.1Resale Registration Rights.

(a)The Company agrees that, as promptly as reasonable practicable after the consummation of the Transaction, but in any event within 150 calendar days after such consummation, the Company will file with the Commission (at the Company’s sole cost and expense) a registration statement registering the resale of the Registrable Securities (the “Registration Statement”), and the Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 210th calendar day (or 270th calendar day if the Commission notifies the Company that it will “review” the Registration Statement) following the closing of the Transaction and (ii) the 10th Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effective Date”); provided, however, that the Company’s obligations to include the Registrable Securities held by a Holder in the Registration Statement are contingent upon such Holder furnishing in writing to the Company such information regarding such Holder, the securities of the Company held by such Holder and the intended method of disposition of the Registrable Securities as shall be reasonably requested by the Company to effect the registration of the applicable Registrable Securities, and the Holder shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement for such applicable selling stockholder during any applicable and customary blackout or similar period or as permitted hereunder. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Registrable Securities by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Registrable Securities which is equal to the maximum number of Registrable

2

Securities as is permitted by the Commission. In such event, the number of Registrable Securities to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders. Upon notification by the Commission that the Registration Statement has been declared effective by the Commission, within one (1) Business Day thereafter, the Company shall file the final prospectus under Rule 424 of the Securities Act. In no event shall any Holder be identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided, that if the Commission requests that a Holder be identified as a statutory underwriter in the Registration Statement, such Holder will have an opportunity to withdraw from the Registration Statement. For purposes of clarification, any failure by the Company to file the Registration Statement within 150 calendar days after the consummation of the Transaction or to effect such Registration Statement by the Effective Date shall not otherwise relieve the Company of its obligations to file or effect the Registration Statement as set forth above in this Section 2.1(a).

(b)Notwithstanding anything to the contrary in this Agreement, the Company shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require the Holder not to sell under the Registration Statement or to suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event the Company reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Company in the Registration Statement of material information that the Company has a bona fide business purpose for keeping confidential and the Company reasonably believes, upon the advice of legal counsel, that non-disclosure of such information in the Registration Statement would cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided, however, that the Company may not delay or suspend the Registration Statement on more than three (3) occasions or for more than sixty (60) total calendar days, in each case during any twelve-month period. Upon receipt of any written notice from the Company of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, each Holder agrees that (i) it will immediately discontinue offers and sales of the Registrable Securities under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until such Holder receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law or subpoena. If so directed by the Company, each Holder will deliver to the Company or, in such Holder’s sole discretion destroy, all copies of the prospectus covering the Registrable Securities in the Holder’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Securities shall not apply (1) to the extent the Holder is required to retain a copy of such prospectus (x) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (y) in accordance with a bona fide pre- existing document retention policy or (2) to copies stored electronically on archival servers as a result of automatic data back-up. Notwithstanding anything to the contrary set forth in this Section, without the prior written approval of the Holder, the Company shall not, when advising the Holder of any of the events set forth in this Section, provide the Holder with any material, non-public information regarding the Company other than to the extent that providing notice to the Holder of the occurrence of such events listed above may constitute material, non-public information regarding the Company.

2.2Sales and Underwritten Offerings of the Registrable Securities.

(a)If the Company proposes to conduct an Underwritten Offering for its own account or for the account of any other person, each Specified Investor shall have the right to include in such Underwritten Offering all or part of the Registrable Securities held by such Specified Investor, subject to the provisions of Section 2.2(b) and solely to the extent such Registrable Securities can be sold pursuant to the Registration Statement or a Replacement Registration Statement (the “Piggyback Rights”). Except as otherwise provided in Section 2.3, to the extent a Specified Investor is entitled to Piggyback Rights hereunder, the Company shall promptly, but in no event less than five Business Days prior to any such Underwritten Offering (or, in the event of an Underwritten Offering that will be executed as an “overnight” or “bought” deal, no less than two Business Days prior to the commencement of such Underwritten Offering), give written notice to such Specified Investor (so long as such Specified Investor continues to hold at least 50% of the sum of (x) the shares of Common Stock issued to such Specified Investor in the PIPE Investment and (y) any shares of Common Stock or shares of Series A Preferred Stock (including any shares of Common Stock issued upon conversion thereof) distributed to such Specified Investor by Arq) of its intention to conduct such Underwritten Offering. If a Specified Investor is entitled to Piggyback Rights hereunder and wishes to exercise its Piggyback Rights it shall deliver to the Company a written notice (i) within two Business Days after the receipt of the Company’s notice or (ii) at least one day prior to the first use of a preliminary prospectus in connection with such Underwritten Offering, whichever is earlier. A Specified Investor’s written notice shall specify the number of Registrable Securities intended to be disposed of by such Specified Investor. If a Specified Investor is entitled to Piggyback Rights hereunder, the Company will, subject to Section 2.2(b), use its commercially reasonable efforts to effect the registration under the Securities Act of, and to include in the Underwritten Offering, all Registrable Securities which the Company has been so requested to register by the applicable Specified Investor, to the extent requisite to permit the disposition of the Registrable Securities so to be registered and sold; provided that if, at any time after giving written notice of its intention to conduct the Underwritten Offering and prior to the commencement of the Underwritten Offering, the Company shall determine for any reason not to proceed with the Underwritten Offering, the Company may, at its election, give written notice of such determination to the applicable Specified Investor and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such Underwritten Offering. Each Specified Investor electing to sell any shares in such Underwritten Offering must sell its Registrable Securities to the underwriters selected by the Company on the same terms and conditions as apply to the Company (including entering into an underwriting agreement in customary form with the underwriter or underwriters selected for such offering by the Company), as may be customary or appropriate in for offerings of the type being conducted, except that indemnification and contribution by and of the Specified Investors shall be consistent with this Agreement, mutatis mutandis. For purposes of this Agreement, (i) “Underwritten Offering” means an offering (including an offering pursuant to the Registration Statement) in which shares of Common Stock are sold to an underwriter on a firm commitment basis for reoffering to the public or an offering that is a “bought deal” with one or more investment banks and (ii) “Specified Investor” means Arq and any other Investor who both (i) either (1) has an Aggregate Subscription Amount (as such term is defined in the Subscription Agreements) in the PIPE Investment of at least $2,000,000 or (2) is an Affiliate of the Company on the applicable date and (ii) continues to hold at least 50% of the sum of (x) the shares of Common Stock issued to such Investor in the PIPE Investment and (y) any shares of Common Stock or Series A Preferred Stock (including any shares of Common Stock issued upon conversion thereof) distributed to such Investor by Arq; provided that the holdings of each of York Global Finance 48, LLC, York Global Finance 47, LLC, YGF 100 LP, York European Distressed Credit Fund II LP, Dinan Management LP, Schwartz Management LLC, York Distressed Asset Fund IV LP and Exuma Capital LP and each of their respective Affiliates (collectively, the “York Parties”) shall be aggregated for purposes of determining whether any York Party is a Specified Investor.

(b)If the managing underwriter in any Underwritten Offering determines in good faith that marketing factors require a limitation on the number of securities to be underwritten, the number of securities that may be included will be limited to the number of securities that, in the opinion of such underwriter, should be included, and the securities to be included in the underwriting shall be allocated, as follows: (i) first, to the Company, (ii) second, among Arq and the Specified Investors that elect to participate in such Underwritten Offering, and (iii) third, pro rata among any other Persons who have been or are granted registration rights

4

after the date of this Agreement based on the number of securities validly requested to be included by such Persons.

2.3Opt-Out Notice. Each Holder may deliver written notice (an “Opt-Out Notice”) to the Company requesting that such Holder not receive notices from the Company otherwise required by this Agreement; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from a Holder (unless subsequently revoked), (i) the Company shall not deliver any such notices to such Holder and such Holder shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to such Holder’s intended use of an effective Registration Statement, such Holder will notify the Company in writing at least two (2) Business Days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section 2.3) and the related suspension period remains in effect, the Company will so notify such Holder, within one (1) Business Day of such Holder’s notification to the Company, by delivering to such Holder a copy of such previous notice of Suspension Event, and thereafter will provide such Holder with the related notice of the conclusion of such Suspension Event immediately upon its availability.

2.4Fees and Expenses. The Company shall be responsible for all expenses incurred by the Company in connection with registrations, filings, or qualifications pursuant to this Agreement, including all registration, filing, and qualification fees; printers’ and accounting fees; and fees and disbursements of counsel for the Company. Except as otherwise provided in Section 2.8 hereof, the Company shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. In addition, the Company shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions and transfer taxes allocable to the sale of the Registrable Securities, or expenses incurred by a Holder in connection with delivering any applicable certifications or legal opinions.

2.5Registration Procedures. In the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform the Holders as to the status of such registration, qualification, exemption and compliance. At its expense the Company shall:

(a)except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which the Company determines to obtain, continuously effective with respect to the each Holder, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (1) each Holder ceases to hold any Registrable Securities or (2) the date all Registrable Securities held by all Holders may be sold without restriction under Rule 144 promulgated under the Securities Act, including without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 promulgated under the Securities Act and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) or Rule 144(i)(2), as applicable, and (3) two years from the Effective Date of the Registration Statement.

(b)advise each Holder within five (5) Business Days:

(i)when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any post-effective amendment thereto has become effective;

(ii)of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information;

(iii)of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for such purpose;

5

(iv)of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(v)subject to the provisions in this Agreement, of the occurrence of any event that requires the making of any changes in the Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising a Holder of such events, provide such Holder with any material, nonpublic information regarding the Company other than to the extent that providing notice to such Holder of the occurrence of the events listed in (1) through (5) above constitutes material, nonpublic information regarding the Company;

(c)use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of the Registration Statement as soon as reasonably practicable;

(d)upon the occurrence of any event contemplated above, except for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(e)use its commercially reasonable efforts to cause all Registrable Securities to be listed on each securities exchange or market, if any, on which the Common Stock issued by the Company have been listed;

(f)use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities contemplated hereby and, for so long as a Holder holds Registrable Securities, to enable such Holder to sell the such Registrable Securities under Rule 144; and

(g)remove the Securities Act legend (or instruct its transfer agent to so remove such legend) from the Registrable Securities if (1) the Registration Statement has become effective under the Securities Act and the applicable holder notifies the Company that such Registrable Securities have been sold pursuant to the Registration Statement, (2) such Registrable Securities are sold or transferred pursuant to Rule 144 (if the transferor is not an Affiliate of the Company), or (3) such Registrable Securities are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable) as to such securities and without volume or manner-of-sale restrictions. Each applicable holder agrees to provide the Company, its counsel and/or the transfer agent with evidence reasonably requested by it (including but not limited to an opinion of counsel reasonably acceptable to the Company) in order to cause the removal of the Securities Act legend (the “Representations”). If a legend is no longer required pursuant to the foregoing, the Company will no later than three (3) Business Days following the delivery by an applicable holder to the Company or the transfer agent (with notice to the Company) of a legended certificate or instrument representing Registrable Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) and the Representations, deliver or cause to be delivered to such applicable holder a certificate or instrument (as the case may be) representing such Registrable Securities that is free from all restrictive legends. Certificates for Registrable Securities free from all restrictive legends may be transmitted by the transfer agent to the applicable holders by crediting the account of the applicable holder’s prime broker with DTC as directed by such applicable holder.

6

2.6Replacement Registration Statement. Upon the expiration of the Registration Statement, at any time that an Investor is a Specified Investor, then on one occasion, Arq or holders of at least 30% of the Registrable Securities held by all of the Specified Investors shall be entitled to direct the Company to file a new Registration Statement to replace the Registration Statement that was filed pursuant to this Agreement (the “Replacement Registration Statement”). The Company shall promptly, and in any event within 45 days of such a request, file the Replacement Registration Statement, and the Company shall use its commercially reasonable efforts to have such Replacement Registration Statement declared effective and to keep effective the Replacement Registration Statement as if such replacement registration statement were the Registration Statement.

2.7The Holders’ Obligations.

(a)Compliance with Prospectus Delivery Requirements. The Holders covenant and agree that they shall comply with the prospectus delivery requirements of the Securities Act as applicable to them or an exemption therefrom in connection with sales of Registrable Securities pursuant to any Registration Statement filed by the Company pursuant to this Agreement.

(b)Notification of Sale of Registrable Securities. The Holders covenant and agree that they shall notify the Company following the sale of Registrable Securities to a third party as promptly as reasonably practicable, and in any event within thirty (30) days, following the sale of such Registrable Securities.

2.8Indemnification.

(a)The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and hold harmless each Holder (to the extent a seller under the Registration Statement), the officers, directors and agents of such Holder, and each person who controls such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all out-of-pocket losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, , except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding the Holder furnished in writing to the Company by the Holder expressly for use therein or the Holder has omitted a material fact from such information ; provided, however, that the indemnification contained in this Section 2.8 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld, conditioned or delayed) nor shall the Company be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (1) reliance upon and in conformity with written information furnished by the Holder, (2) in connection with any failure of such person to deliver or cause to be delivered a prospectus made available by the Company in a timely manner or (3) in connection with any offers or sales effected by or on behalf of the Holder in violation hereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the Transfer of the Registrable Securities by the Holder. For purposes of this Agreement, “Transfer” shall mean any direct or indirect transfer, redemption, disposition or monetization in any manner whatsoever, including, without limitation, through any derivative transactions.

(b)Each Holder shall, severally and not jointly with any other Holder, indemnify and hold harmless the Company, its directors, officers, agents and employees, and each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, (i) arising out of or based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus

7

included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or (ii) arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, with respect to (i) and/or (ii), to the extent, but only to the extent, that such untrue or alleged untrue statements or omissions or alleged omissions are based upon information regarding a Holder furnished in writing to the Company by a Holder expressly for use therein. In no event shall the liability of an Investor be greater in amount than the dollar amount of the net proceeds received by such Investor upon the sale of the Registrable Securities giving rise to such indemnification obligation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the Transfer of the Registrable Securities by the applicable Investor.

(c)Any person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one (1) counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d)If the indemnification provided under this Section 2.8 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the Losses shall be deemed to include, subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 2.8 from any person who was not guilty of such fraudulent misrepresentation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 2.8 shall be several, not joint. In the case of the PIPE Investors, in no event shall the liability of the Investor be greater in amount than the dollar amount of the net proceeds received by the PIPE Investor upon the sale of the Registrable Securities purchased pursuant to the Subscription Agreement giving rise to such contribution obligation.

(e)Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control; provided, however, that the failure of the underwriting agreement to provide for or address a matter provided for or addressed by the foregoing provisions shall not be a conflict between the underwriting agreement and the foregoing provisions.

8

2.9Information. The Holders shall furnish to the Company such information regarding the Holders and the distribution proposed by the Holders as the Company may reasonably request and as shall be reasonably required in connection with any registration referred to in this Agreement. The Holders agree to, as promptly as practicable (and in any event prior to any sales made pursuant to a prospectus), furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by the Holders not misleading. Notwithstanding anything to the contrary herein, the Company shall be under no obligation to name the Holders in any Registration Statement if the Holders have not provided the information required by this Section 2.9 with respect to the Holders as a selling securityholder in such Registration Statement or any related prospectus.

Section 3.
Miscellaneous

3.1Amendment. This Agreement may not be amended, modified, supplemented or waived except by a written amendment signed by the Company and the Holders of a majority of the then outstanding Registrable Securities.

3.2Transfer or Assignment of Registration Rights.

The Company shall be given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and identifying the securities with respect to which such registration rights are being transferred or assigned, and each such transferee shall assume in writing responsibility for its obligations of such Investor under this Agreement.

3.3Injunctive Relief.

3.4Notices. Any notice or communication required or permitted hereunder shall be in writing and either delivered personally, emailed, sent by overnight mail via a reputable overnight carrier, or sent by certified or registered mail, postage prepaid, and shall be deemed to be given and received (i) when so delivered personally, (ii) when sent, with no mail undeliverable or other rejection notice, if sent by email, or (iii) five (5) Business Days after the date of mailing to (a) with respect to the Company, the address (including email address) below and (b) with respect to each Holder, the address (including email address) set forth below the name of such Holder on the signature pages hereto (or the applicable joinder hereto), or to such other address or addresses as such person may hereafter designate by notice given hereunder:

3.5Governing Law; Jurisdiction; Venue; Jury Trial.

(a)This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of laws. In any action or proceeding between any of the parties arising out of or relating to this Agreement or any of the transaction contemplated herein, each of the parties: (a) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the United States District Court for the District of Delaware; (b) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (a) of this Section 3.4(a); (c) waives any objection to laying venue in any such action or proceeding in such courts; (d) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any party; and (e) agrees that service of process upon such party in any such action or proceeding shall be effective if notice is given in accordance with Section 3.3 of this Agreement.

(b)EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS SUBSCRIPTION AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7(L).

10

3.6Successors and Assigns. Except as otherwise provided herein, this Agreement shall be binding upon, and inure to the benefit of the parties hereto and their successors and permitted assigns (to the extent permitted pursuant to Section 3.2), and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such successors and permitted assigns.

3.7Entire Agreement. This Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof.

3.8Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

3.9Counterparts. This Subscription Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Subscription Agreement (in counterparts or otherwise) by all parties hereto by electronic transmission in .PDF format shall be sufficient to bind the parties to the terms and conditions of this Subscription Agreement.

3.10Term and Termination. This Agreement shall terminate upon the earlier of (i) the date each Holder ceases to hold any Registrable Securities, (ii) the date all Registrable Securities held by all Holders may be sold without restriction under Rule 144 promulgated under the Securities Act, including without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 promulgated under the Securities Act and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) or Rule 144(i)(2), as applicable, and (iii) two years from the Effective Date of the Registration Statement.

Section 2.1Loan.

(a)Subject to the terms and conditions and relying upon the representations and warranties herein set forth, each Lender severally agrees to make its portion of a term loan (the “Loan”) available to Debtor on the Closing Date in the aggregate principal amount not to exceed such Lender’s Term Loan Commitment. Notwithstanding the foregoing, the aggregate principal amount of the Loan made available to Debtor on the Closing Date shall not exceed the Total Term Loan Commitment. Any principal amount of the Loan which is repaid or prepaid may not be reborrowed. The Loan may be a Base Rate Loan or SOFR Loan, as further provided herein.

(b)Except as otherwise provided in this Section 2.1(b), all Loans under this Agreement shall be made by the Lenders simultaneously and proportionately to their Pro Rata Shares of the Total Term Loan Commitment, it being understood that no Lender shall be responsible for any default by any other Lender in that other Lender’s obligations to make a Loan requested hereunder, nor shall the Term Loan Commitment of any Lender be increased or decreased as a result of the default by any other Lender in that other Lender’s obligation to make a Loan requested hereunder, and each Lender shall be obligated to make the Loans required to be made by it by the terms of this Agreement regardless of the failure by any other Lender. Subject to satisfaction of the conditions precedent in Section 5.1, not later than 10:00 a.m., on the Closing Date, each Lender shall make available to the Administrative Agent’s Account an amount in immediately available funds equal to the Loan to be made by such Lender; provided, that the Loan shall be issued on the Closing Date with original issue discount of 2.00%.

(d)The entries made in the registers maintained pursuant to Section 2.2(b) or Section 2.2(c) shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that (i) the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of Debtor to repay the Loans in accordance with the terms of this Agreement and (ii) in the event of any conflict between the entries made in the accounts maintained pursuant to Section 2.2(b) and the accounts maintained pursuant to Section 2.2(c), the accounts maintained pursuant to Section 2.2(c) shall govern and control.

Each such notice shall specify the date and amount of such prepayment and the Type(s) of Loans to be prepaid and, if SOFR Loans are to be prepaid, the Interest Period(s) of such Loans. All voluntary prepayments of the Loans in accordance with this Section 2.5 shall be applied to the outstanding principal of the Loans as directed by Debtor, or in the absence of any direction, against the remaining installments of principal outstanding in respect of the Loan in the direct order of maturity.

Upon the occurrence and during the continuance of any Event of Default, the Administrative Agent shall also be authorized (without any further action by or notice from Debtor or any other Loan Party) to apply such amount to the prepayment of the outstanding principal of the Loans in accordance with the relevant provisions of this Section 2.6.

(h)Notwithstanding any other provisions of this Section 2.6, (i) to the extent that the repatriation (or other distribution) to Debtor of any or all of the Net Cash Proceeds of any Disposition by a Foreign Subsidiary (“Foreign Disposition”) or the Net Cash Insurance Proceeds in respect of damaged Collateral of a Foreign Subsidiary (“Foreign Casualty Event”) would (x) be prohibited or delayed by applicable local Requirements of Law, (y) be restricted by applicable material constituent documents or (z) conflict with the fiduciary duties of such Foreign Subsidiary’s directors, or result in, or would reasonably be expected to result in, a material risk of personal or criminal liability for any officer, director, employee, manager, member of management or consultant of such Foreign Subsidiary (including on account of financial assistance, corporate benefit, thin capitalization, capital maintenance or similar considerations), an amount equal to the Net Cash Proceeds or insurance proceeds, as applicable, that would be so affected were Debtor to attempt to repatriate such cash (or effect such intercompany distribution) will not be required to be applied to repay the Loans at the times provided in this Section 2.6 so long, but only so long, as the applicable local Requirements of Law or applicable material constituent documents would not otherwise permit repatriation (or intercompany distribution) to the Debtor and, to the extent applicable, would not conflict with the fiduciary duties of such director, or result in, or reasonably be expected to result in, a material risk of personal or criminal liability for the persons described above; it being understood that (A) with respect to clauses (x) and (y), Debtor shall take all commercially reasonable actions required by applicable Requirements of Law to permit such repatriation (or intercompany distribution) and (B) once such repatriation (or intercompany distribution) of any of such affected Net Cash Proceeds of any Foreign Disposition or Net Cash Insurance Proceeds of any Foreign Casualty Event is permissible under the applicable local Requirements of Law or applicable material constituent documents (even if such cash is actually not repatriated or distributed), an amount equal to the amount of the Net Cash Proceeds or Net Cash Insurance Proceeds, as applicable, that could be repatriated or distributed will be promptly (and in any event not later than ten (10) Business Days after such repatriation or intercompany distribution) applied (net of an amount equal to the additional taxes of Debtor and its Subsidiaries that would be payable or reserved against as a result of a repatriation or intercompany distribution and any additional costs that would be incurred as a result of a repatriation or intercompany distribution, whether or not a repatriation or an intercompany distribution actually occurs) by Debtor to the repayment of the Loans pursuant to this Section 2.6, and (ii) to the extent that Debtor has determined in good faith that repatriation or intercompany distribution of any of or all the Net Cash Proceeds of any Foreign Disposition or Net Cash Insurance Proceeds of any Foreign Casualty Event would have material adverse tax cost consequences with respect to such Net Cash Proceeds or Net Cash Insurance Proceeds, as applicable, an amount equal to such Net Cash Proceeds or Net Cash Insurance

38

Proceeds, as applicable, that would be so affected will not be subject to repayment under this Section 2.6 until such time as such amount can be upstreamed or transferred without incurring such material adverse tax cost consequence; provided that in the case of each of clauses (i) and (ii), such nonpayment prior to the time such amounts must be repatriated or distributed shall not constitute an Event of Default (and such amounts shall be available (A) first, to repay local foreign indebtedness, if any, and (B) thereafter, for working capital purposes of Debtor and its Subsidiaries, in each case, subject to the prepayment provisions in this Section 2.6(h)). For the avoidance of doubt, nothing in this Section 2.6 shall require Debtor to cause any amounts to be repatriated or distributed to Debtor (whether or not such amounts are used in or excluded from the determination of the amount of any mandatory prepayments hereunder).

(i)Debtor shall provide written notice to the Administrative Agent, not later than 1:00 p.m. five (5) Business Days prior to each prepayment required under this Section 2.6, and such prepayment notice shall specify the prepayment date, the Type of each Loan being prepaid, the principal amount of each Loan (or portion thereof) to be prepaid and the Prepayment Premium that will be due and payable in connection with such prepayment.The Administrative Agent will promptly (and in any event within one (1) Business Day) notify each Lender of the contents of Debtor’s prepayment notice and of each Lender’s Pro Rata Share of the prepayment. Each Lender may reject all of its Pro Rata Share of any mandatory prepayment (such declined amounts, the “Declined Proceeds”) of the Loans required to be made pursuant to clauses (b) and (c) of this Section 2.6 by providing written notice (each, a “Rejection Notice”) to the Administrative Agent no later than 5:00 p.m. three (3) Business Day after the date of such Lender’s receipt of notice from the Administrative Agent regarding such prepayment. If a Lender fails to deliver a Rejection Notice to the Administrative Agent within the time frame specified above such failure will be deemed an acceptance of the total amount of such mandatory prepayment of the Loans. Any proceeds declined by the Lenders shall be retained by Debtor for application for any purpose not prohibited by this Agreement.

Section 2.7Business Days. If the date for any payment or prepayment hereunder falls on a day which is not a Business Day, then for all purposes of this Agreement the payment shall be due on the following Business Day.

Section 2.8Payments.

(a)Debtor will make each payment under this Agreement not later than 12:00 noon on the day when due, in lawful money of the United States of America and in immediately available funds, to the Administrative Agent’s Account. All payments received by the Administrative Agent after 12:00 noon on any Business Day will be credited to the Register on the next succeeding Business Day. All payments shall be made by Debtor without set-off, counterclaim, recoupment, deduction or other defense to the Administrative Agent and the Lenders. After receipt, the Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal ratably to the Lenders in accordance with their Pro Rata Shares and like funds relating to the payment of any other amount payable to any Lender to such Lender, in each case to be applied in accordance with the terms of this Agreement. Whenever any payment to be made under any such Loan Document shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall in such case be included in the computation of interest or fees, as the case may be. All computations of fees shall be made by the Administrative Agent on the basis of a year of 360 days for the actual number of days. Each determination by the Administrative Agent of an interest rate or fees hereunder shall be conclusive and binding for all purposes in the absence of manifest error.

(b)The Administrative Agent shall provide Debtor, promptly after the end of each calendar month in which there is activity on the Loan, a summary statement (in the form from time to time used by the Administrative Agent) of the amounts and dates of all Loans made to Debtor during such month, the amounts and dates of all payments on account of the Loan to Debtor during such month and the Loans to which such payments were applied, and the amount of interest accrued on the Loan to

39

Debtor during such month. All entries on any such statement shall be presumed to be correct and, 30 days after the same is sent, shall be final and conclusive absent manifest error.

(c)If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of any Obligation in excess of its ratable share of payments on account of similar obligations obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in such similar obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that (i) if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and each Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (A) the amount of such Lender’s required repayment to (B) the total amount so recovered from the purchasing Lender) of any interest or other amount paid by the purchasing Lender in respect of the total amount so recovered and (ii) the provisions of this Section shall not be construed to apply to (A) any payment made by Debtor pursuant to and in accordance with the express terms of this Agreement, (B) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to any Loan Party or any Subsidiary thereof (as to which the provisions of this Section shall apply) or (C) any payment received by such Lender not in its capacity as a Lender. Debtor agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.8(c) may, to the fullest extent permitted by law, exercise all of its rights (including the Lender’s right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of Debtor in the amount of such participation.

(d)All payments of principal and interest in respect of outstanding Loans, all payments of fees and all other payments in respect of any other Obligations, shall be allocated by the Administrative Agent among such of the Lenders as are entitled thereto, in proportion to their respective Pro Rata Shares or otherwise as provided herein or, in respect of payments not made on account of Loans, as designated by the Person making payment when the payment is made.

(e)(i) After the occurrence and during the continuance of an Event of Default described in Section 6.1(a), (f) or (m), (ii) after the acceleration of the Loans pursuant to Article VII, (iii) after the exercise of enforcement remedies by the Administrative Agent (acting at the written direction of Required Lenders) pursuant to the Loan Documents or (iv) otherwise upon the written direction of the Required Lenders, after the occurrence and during the continuance of an Event of Default, in each case, the Administrative Agent shall apply all payments in respect of any Obligations, including, without limitation, proceeds of the Collateral and any amounts received on account of the Obligations (whether received as a consequence of the exercise of any remedies under Article VII hereof or any other Loan Document or as a distribution out of any proceeding in respect of or commenced under any Insolvency Proceeding including payments in respect of “adequate protection” for the use of Collateral during such proceeding or under any Plan of Reorganization or on account of any liquidation of any Loan Party), subject to the provisions of this Agreement, (A) first, ratably to pay the Obligations in respect of any fees, expense reimbursements, indemnities and other amounts then due and payable to the Administrative Agent and its agents and attorneys until paid in full; (B) second, ratably to pay the Obligations in respect of any fees, expense reimbursements, indemnities and other amounts (other than interest or principal) then due and payable to the Lenders until paid in full; (C) third, ratably to pay interest then due and payable in respect of the Loan until paid in full; (D) fourth, ratably to pay principal of the Loan until paid in full; and (E) fifth, to the ratable payment of all other Obligations then due and payable.

(f)For purposes of Section 2.8(e), “paid in full” means payment in cash of the applicable amounts owing under the Loan Documents according to the terms thereof.

40

(g)In the event of a conflict between the priority provisions of Section 2.8(e) and 2.8(f) and other provisions contained in any other Loan Document, the terms and provisions of such Sections shall control and govern.

Section 2.9Maturity Date. The Loan will terminate on the Maturity Date, and all principal and interest then outstanding under the Loan shall be due and payable on such date.

Section 2.10Use of Proceeds. Debtor shall use the proceeds of the Loan for general corporate purposes, including certain Capital Expenditures and other expenses as outlined in the Business Plan.

Section 2.11Taxes.

(a)Any and all payments by or on account of any Loan Party hereunder or under any other Loan Document shall be made free and clear of and without deduction for any and all Taxes, except as required by applicable law. If any Loan Party shall be required to deduct any Taxes from or in respect of any sum payable hereunder to any Secured Party, (i) the applicable Withholding Agent shall make such deductions, (ii) the applicable Withholding Agent shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law and (iii) if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased by the amount necessary such that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.11) such Secured Party receives the amount equal to the sum it would have received had no such deductions been made.

(b)In addition, each Loan Party agrees to pay to the relevant Governmental Authority in accordance with applicable law any Other Taxes. Each Loan Party shall deliver to each Secured Party official receipts in respect of any Taxes or Other Taxes payable hereunder promptly after payment of such Taxes or Other Taxes.

(c)The Loan Parties hereby jointly and severally indemnify and agree to hold each Secured Party harmless from and against any Indemnified Taxes (including, without limitation, Indemnified Taxes imposed on any amounts payable under this Section 2.11) paid by such Person, whether or not such Indemnified Taxes were correctly or legally asserted. Such indemnification shall be paid within ten (10) days from the date on which any such Person makes written demand therefore specifying in reasonable detail the nature and amount of such Indemnified Taxes.

(d)Each Lender shall, at such times as are reasonably requested by Debtor or the Administrative Agent, provide Debtor and the Administrative Agent with any documentation prescribed by law or reasonably requested by Debtor or the Administrative Agent certifying as to any entitlement of such Lender to an exemption from, or reduction in, withholding Tax with respect to any payments to be made to such Lender under the Loan Documents. In addition, any Lender, if reasonably requested by Debtor or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by Debtor or the Administrative Agent as will enable Debtor or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Each such Lender shall, whenever a change in circumstances renders such documentation inaccurate in any material respect, deliver promptly to Debtor and the Administrative Agent updated or other appropriate documentation (including any new documentation reasonably requested by Debtor or the Administrative Agent) or promptly notify Debtor and the Administrative Agent in writing of its inability to do so. Unless the applicable Withholding Agent has received forms or other documents satisfactory to it indicating that payments under any Loan Document to or for a Lender are not subject to withholding Tax or are subject to such Tax at a rate reduced by an applicable tax treaty, the applicable Withholding Agent shall withhold amounts required to be withheld by applicable law from such payments at the applicable statutory rate and such Withholding Agent shall have no liability for doing so. Notwithstanding any other provision of this Section 2.11(d), a Lender shall not be required to provide or deliver any document or form pursuant to this Section 2.11(d) (x) that such Lender is not

41

legally able to deliver or (y) (other than such documentation set forth in Section 2.11(d)(i), Section 2.11(d)(ii), Section 2.11(d)(iv) and Section 2.11(d)(v) below) if in the such Lender’s judgment such provision or delivery would subject such Lender to any unreimbursed cost or expense or would otherwise prejudice the legal or commercial position of such Lender. Without limiting the foregoing:

(i)Each Lender that is a United States person (as defined in Section 7701(a)(30) of the IRC) shall deliver to Debtor and the Administrative Agent, on or before the date on which it becomes a party to this Agreement, two properly completed and duly signed copies of Internal Revenue Service Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax.

(ii)Each Lender that is not a United States person (as defined in Section 7701(a)(30) of the IRC) (a “Non-U.S. Lender”) shall deliver to Debtor and the Administrative Agent, on or before the date on which it becomes a party to this Agreement (and from time to time thereafter upon the request of Debtor or the Administrative Agent), whichever of the following is applicable:

(A)two properly completed and duly signed copies of Internal Revenue Service Form W-8BEN or Form W-8BEN-E (or any successor forms) claiming eligibility for the benefits of an income tax treaty to which the United States is a party, and such other documentation as required under the IRC,

(B)two properly completed and duly signed copies of Internal Revenue Service Form W-8ECI (or any successor forms),

(C)in the case of a Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the IRC, (1) a certificate (any such certificate a “Certificate Regarding Non-Bank Status”) certifying that such Non-U.S. Lender is not (A) a “bank” within the meaning of Section 881(c)(3)(A) of the IRC, (B) a “10 percent shareholder” of Debtor, within the meaning of Section 881(c)(3)(B) of the IRC or (C) a “controlled foreign corporation” described in Section 881(c)(3)(C) of the IRC, and that no interest payments in connection with the Loan Documents are effectively connected with such Lender’s conduct of a U.S. trade or business and (2) two properly completed and duly signed copies of Internal Revenue Service Form W-8BEN or Form W-8BEN-E (or any successor forms), or

(D)to the extent a Lender is not the beneficial owner, Internal Revenue Service Form W-8IMY (or any successor forms) of the Lender, accompanied by a Form W-8ECI, Form W-8BEN, Form W-8BEN-E, a Certificate Regarding Non-Bank Status, or Form W-9, or Form W-8IMY.

(iii)any other form prescribed by applicable law as a basis for claiming exemption from or a reduction United States federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit Debtor or the Administrative Agent to determine the withholding or deduction required to be made.

(iv)In addition, the Administrative Agent shall deliver to Debtor (x)(I) prior to the date on which the first payment by Debtor is due hereunder or (II) prior to the first date on or after the date on which the Administrative Agent becomes a successor Administrative Agent pursuant to Article VIII on which payment by Debtor is due hereunder, as applicable, two copies of whichever of the following is applicable: (A) a properly completed and executed Internal Revenue Service Form W-9 certifying its exemption from U.S. federal backup withholding or (B) a properly completed and executed Internal Revenue Service Form W-8IMY certifying that the Administrative Agent is a U.S. branch and intends to be treated as a U.S. person for purposes of withholding under Chapter 3 of the IRC pursuant to Section 1.1441-1(b)(2)(iv) of the Treasury Regulations and (y) on or before the date on which any such

42

previously delivered documentation becomes inaccurate in any respect, updated documentation. Notwithstanding anything to the contrary in this Section 2.11(d)(iv), the Administrative Agent shall not be required to deliver any documentation that the Administrative Agent is not legally eligible to deliver as a result of a Change in Law.

(v)If a payment made to a Lender or the Administrative Agent under any Loan Document would be subject to U.S. federal withholding Tax imposed under FATCA if such Lender or Administrative Agent were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the IRC, as applicable), such Lender or Administrative Agent shall deliver to Debtor and the Administrative Agent at the time or times prescribed by laws and at such time or times reasonably requested by Debtor and the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the IRC) and such additional documentation reasonably requested by Debtor or the Administrative Agent as may be necessary for Debtor and the Administrative Agent to comply with their obligations under FATCA and to determine whether such Lender or Administrative Agent has or has not complied with such Lender’s obligations under FATCA and, if necessary, to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 2.11(d), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(e)Each Lender hereby authorizes the Administrative Agent to deliver to the Loan Parties and to any successor Administrative Agent any documentation provided by such Lender to the Administrative Agent pursuant to Section 2.11(d).

(f)If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.11 (including by the payment of additional amounts pursuant to this Section 2.11), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 2.11 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this clause (f) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this clause (f), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this clause (f) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This clause (f) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(g)Notwithstanding anything herein to the contrary, Debtor and each Lender hereby agrees that the Administrative Agent shall be entitled to make any withholding or deduction from payments to the extent necessary to comply with FATCA for which the Administrative Agent shall not have liability and to provide to the Administrative Agent sufficient information about Lenders or other applicable parties and/or transactions (including any modification to the terms of such transactions) so the Administrative Agent can determine whether it has tax related obligations under applicable tax laws, rules and regulations (inclusive of directives, guidelines and interpretations promulgated by competent authorities) in effect from time to time. Debtor agrees to indemnify and hold harmless the Administrative Agent for any losses it may suffer due to actions it takes to comply with FATCA, except to the extent that there has been a final non-appealable judicial determination that such losses resulted from the Administrative Agent’s gross negligence or willful misconduct.

43

(h)The obligations of the Loan Parties under this Section 2.11 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

Section 2.12Increased Costs and Reduced Return.

(a)If any Change in Law shall (i) subject such Secured Party to any Tax (other than an Indemnified Tax or an Excluded Tax) with respect to this Agreement or any Loan made by such Lender, (ii) impose, modify or deem applicable any reserve, special deposit or similar requirement against any Loan or against assets of or held by, or deposits with or for the account of, or credit extended by, such Secured Party or any Person controlling such Secured Party or (iii) impose on such Secured Party or any Person controlling such Secured Party any other condition regarding this Agreement or any Loan, and the result of any event referred to in clauses (i), (ii) or (iii) above shall be to increase the cost to such Lender of making any Loan or agreeing to make any Loan, or to reduce any amount received or receivable by such Secured Party hereunder, then, upon demand by such Secured Party, Debtor shall pay to such Secured Party such additional amounts as will compensate such Secured Party for such increased costs or reductions in amount.

(b)If any Secured Party shall have determined that any Change in Law either (i) affects or would affect the amount of capital required or expected to be maintained by such Secured Party or any Person controlling such Secured Party, and such Secured Party determines that the amount of such capital is increased as a direct or indirect consequence of any Loans made or maintained hereunder, or such Secured Party’s or such other controlling Person’s other obligations hereunder, or (ii) has or would have the effect of reducing the rate of return on such Secured Party’s or such other controlling Person’s capital to a level below that which such Secured Party or such controlling Person could have achieved but for such circumstances as a consequence of any Loans made or maintained, or any agreement to make Loans or such Secured Party’s or such other controlling Person’s other obligations hereunder (in each case, taking into consideration, such Secured Party’s or such other controlling Person’s policies with respect to capital adequacy), then, upon demand by such Secured Party, Debtor shall pay to such Secured Party from time to time such additional amounts as will compensate such Secured Party for such cost of maintaining such increased capital or such reduction in the rate of return on such Secured Party’s or such other controlling Person’s capital, but only to the extent that such cost or reduction in return is caused solely as a result of its Loan made or maintained hereunder.

(c)All amounts payable under this Section 2.12 shall bear interest from the date that is ten (10) days after the date of demand by any Secured Party until payment in full to such Secured Party at the Base Rate. A certificate of such Secured Party claiming compensation under this Section 2.12, specifying the event herein above described and the nature of such event shall be submitted by such Secured Party to Debtor, setting forth the additional amount due and an explanation of the calculation thereof, and such Secured Party’s reasons for invoking the provisions of this Section 2.12, and shall be final and conclusive absent manifest error.

(d)Failure or delay on the part of any Secured Party to demand compensation pursuant to the foregoing provisions of this Section 2.12 shall not constitute a waiver of such Secured Party’s right to demand such compensation; provided that Debtor shall not be required to compensate a Secured Party pursuant to the foregoing provisions of this Section 2.12 for any increased costs incurred or reductions suffered more than nine months prior to the date that such Secured Party notifies Debtor of the Change in Law giving rise to such increased costs or reductions and of such Secured Party’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

(e)Subject to the provisions of Section 2.12(d), the obligations of the Loan Parties under this Section 2.12 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

44

Section 2.13Funding Losses. Upon written demand of any Lender (with a copy to the Administrative Agent) from time to time, setting forth in reasonable detail the basis for calculating such compensation, Debtor shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense actually incurred by it as a result of:

(a)any payment or prepayment of any Loan on a day other than on an Interest Payment Date (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

(b)any failure by Debtor (for a reason other than the failure of such Lender to make a Loan) to prepay any Loan on the date or in the amount notified by Debtor; or

(c)any mandatory assignment, or assignment at the request of Debtor, of such Lender’s Loans pursuant to Section 2.15 on a day other than an Interest Payment Date;

including any loss or expense (excluding loss of anticipated profits) arising from the liquidation or reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the deposits from which such funds were obtained.

Section 2.14Inability to Determine Rates. Subject to Section 2.16, if, on or prior to the first day of any Interest Period for any SOFR Loan:

(a)the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that Adjusted Term SOFR cannot be determined pursuant to the definition thereof, or

(b)the Required Lenders determine for any reason in connection with any request for a SOFR Loan or a conversion thereto or a continuation thereof that Adjusted Term SOFR for any requested Interest Period with respect to a proposed SOFR Loan does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Loan, and the Required Lenders have provided notice of such determination to the Administrative Agent, the Administrative Agent will promptly so notify the Debtor and each Lender.

Upon notice thereof by the Administrative Agent to Debtor, any right of the Debtor to continue SOFR Loans or to convert Base Rate Loans to SOFR Loans shall be suspended (to the extent of the affected SOFR Loans or affected Interest Periods) until the Administrative Agent (with respect to clause (b), at the instruction of the Required Lenders) revokes such notice. Upon receipt of such notice, (i) the Debtor may revoke any pending request for a conversion to or continuation of SOFR Loans (to the extent of the affected SOFR Loans or affected Interest Periods) or, failing that, the Debtor will be deemed to have converted any such request into a request for a conversion to Base Rate Loans in the amount specified therein and (ii) any outstanding affected SOFR Loans will be deemed to have been converted into Base Rate Loans at the end of the applicable Interest Period. Upon any such conversion, the Debtor shall also pay accrued interest on the amount so converted, together with any additional amounts required pursuant to Section 2.13. Subject to Section 2.16, if the Administrative Agent determines (which determination shall be conclusive and binding absent manifest error) that Adjusted Term SOFR cannot be determined pursuant to the definition thereof on any given day, the interest rate on Base Rate Loans shall be determined by the Administrative Agent without reference to clause (c) of the definition of Base Rate until the Administrative Agent revokes such determination.

Section 2.15Mitigation Obligations; Replacement of Lenders.

(a)If any Lender requires Debtor to pay any additional amount under Section 2.11 or requests compensation under Section 2.12 or 2.13, then such Lender shall (at the request of Debtor) use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable

45

pursuant to such Sections in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Debtor hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)If any Lender requires Debtor to pay any additional amounts under Section 2.11 or requests compensation under Section 2.12 or 2.13 and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with clause (a) above, then Debtor may, at its sole expense and effort, upon written notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.7), all of its interests, rights and obligations under this Agreement and the other Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(i)Debtor shall have paid to the Administrative Agent any assignment fees specified in Section 9.7;

(ii)such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 2.11) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or Debtor (in the case of all other amounts);

(iii)in the case of any such assignment resulting from payments required to be made pursuant to Section 2.11 or a claim for compensation under Section 2.12 or 2.13, such assignment will result in a reduction in such compensation or payments thereafter; and

(iv)such assignment does not conflict with applicable Requirements of Law.

Prior to the effective date of such assignment, the assigning Lender shall execute and deliver an Assignment and Acceptance, subject only to the conditions set forth above. If the assigning Lender shall refuse or fail to execute and deliver any such Assignment and Acceptance prior to the effective date of such assignment, the assigning Lender shall be deemed to have executed and delivered such Assignment and Acceptance. Except as expressly described above, any such assignment shall be made in accordance with the terms of Section 9.7.

(c)A Lender shall not be required to make any such assignment or delegation pursuant to clause (b) above, if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling Debtor to require such assignment and delegation cease to apply.

(d)Subject to the UCC, dispose of, at its office, on the premises of any Loan Party or elsewhere all or any part of the Collateral, as a unit or in parcels, by public or private proceedings, and by way of one or more contracts (it being agreed that the sale of any part of the Collateral shall not exhaust the Administrative Agent’s power of sale, but sales may be made from time to time, and at any time, until all of the Collateral has been sold or until the Obligations have been paid and performed in full), and at any such sale it shall not be necessary to exhibit any of the Collateral;

(e)Subject to the UCC, buy the Collateral, or any part thereof, at any public sale;

(f)Subject to the UCC, sell or buy the Collateral, or any part thereof, at any private sale if the Collateral is of a type customarily sold in a recognized market or is of a type which is the subject of widely distributed standard price quotations;

(g)To the extent permitted by applicable Requirements of Law, whether presently existing or hereafter adopted, of the jurisdiction in which the Collateral or any part thereof is located, require any Loan Party to, and each Loan Party hereby agrees that it will at its expense and upon request of the Administrative Agent (acting at the written direction of the Required Lenders) forthwith, assemble all or part of the Collateral as directed by the Administrative Agent (acting at the written direction of the Required Lenders) and make it available to the Administrative Agent at a place to be designated by the Administrative Agent which is reasonably convenient to all parties;

(h)At its discretion, retain the Collateral in satisfaction of the Obligations whenever the circumstances are such that the Administrative Agent is entitled to do so under the UCC or otherwise;

74

Each Loan Party agrees that, to the extent notice of sale shall be required by law, at least ten (10) calendar days’ notice to Debtor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Administrative Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Administrative Agent may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

Section 7.2Provisions Concerning the Collateral.

(a)Financing Statement Filings. Each Loan Party hereby authorizes the Administrative Agent to file, without the signature of such Loan Party where permitted by law, one or more financing or continuation statements, and amendments thereto, relating to the Collateral. Such statements may: (i) describe the Collateral, and (ii) contain any other information required by the UCC of each jurisdiction in which a financing statement or amendment is filed, including whether such Loan Party is an organization, the type of organization and any organization identification number issued to such Loan Party. Each Loan Party agrees to furnish all such information to the Administrative Agent promptly upon request. Each Loan Party further agrees that a photographic, electronic or other reproduction of this Agreement or any financing statement describing any Collateral is sufficient as a financing statement and may be filed in any jurisdiction the Administrative Agent (acting at the written direction of the Required Lenders) may deem appropriate.

(b)Collection Rights. The Administrative Agent (acting at the written direction of the Required Lenders) shall have the right at any time during the existence of an Event of Default to notify any or all account debtors and other persons obligated under any other Collateral to make payment of all amounts due or to become due to any Loan Party thereunder directly to the Administrative Agent and, upon such notification and at the expense of such Loan Party and to the extent permitted by law, to enforce collection of any such Collateral, and to adjust, settle or compromise the amount or payment thereof, in the same manner and to the same extent as such Loan Party may have done. After the applicable Loan Party receives notice that the Administrative Agent has given any notice referred to above in this subsection, (i) all amounts and proceeds (including instruments and writings) received by any Loan Party in respect of such Collateral, shall be received in trust for the benefit of the Administrative Agent hereunder, shall be segregated from other funds of the Loan Parties and shall be forthwith paid over to the Administrative Agent in the same form as so received (with any necessary endorsement) to be applied to the Obligations, and (ii) no Loan Party will adjust, settle or compromise the amount or payment of any such Collateral, or release wholly or partly any account debtor or obligor thereof or allow any credit or discount thereon. All such funds paid or turned over to the Administrative Agent shall be applied as provided in Section 7.3.

Section 7.3Distribution of Collateral Proceeds. If, following the occurrence and during the continuance of any Event of Default, the Administrative Agent receives any monies in connection with the enforcement of any of the Loan Documents, or otherwise with respect to the realization upon any of the Collateral, such monies shall be applied as set forth in Section 2.8(e).

Section 7.4Deficiency. In the event that the proceeds of any sale, collection or realization of or upon Collateral by the Administrative Agent are insufficient to pay all Obligations and any other amounts to which the Lenders are legally entitled, the Loan Parties shall be, jointly and severally, liable for the deficiency, together with interest thereon as provided in this Agreement or (if no interest is so provided) at such other rate as shall be fixed by applicable law, together with the costs of collection and the reasonable and documented out-of-pocket fees of any attorneys employed by the Administrative Agent to collect such deficiency.

75

Section 7.5Other Recourse. Each Loan Party waives any right to require the Administrative Agent to proceed against any other person, exhaust any Collateral or other security for the Obligations, or to have any Other Liable Party joined with the Loan Parties in any suit arising out of the Obligations or this Agreement, or pursue any other remedy in the Administrative Agent’s power. Each Loan Party further waives any and all notice of acceptance of this Agreement and of the creation, modification, rearrangement, renewal or extension for any period of any of the Obligations of any Other Liable Party from time to time. Each Loan Party further waives any defense arising by reason of any disability or other defense of any Other Liable Party or by reason of the cessation from any cause whatsoever of the liability of any Other Liable Party. Until all of the Obligations shall have been paid in full (other than indemnification and other contingent obligations not then due and payable and as to which no claim has been made at such time), no Loan Party shall have the right to subrogation and each Loan Party waives the right to enforce any remedy which the Administrative Agent has or may hereafter have against any Other Liable Party, and each Loan Party waives any benefit of and any right to participate in any other security whatsoever now or hereafter held by the Administrative Agent. Each Loan Party authorizes the Administrative Agent without notice or demand and without any reservation of rights against such Loan Party without affecting such Loan Party’s liability hereunder or on the Obligations, from time to time to (a) take or hold any other property of any type from any other person as security for the Obligations, and exchange, enforce, waive and release any or all of such other property, (b) subject to the requirements of applicable law, apply the Collateral or such other property and direct the order or manner of sale thereof as the Administrative Agent (acting at the written direction of the Required Lenders) may in its discretion determine, (c) renew, extend for any period, accelerate, modify, compromise, settle or release any of the obligations of any Other Liable Party in respect to any or all of the Obligations or other security for the Obligations, (d) waive, enforce, modify, amend or supplement any of the provisions of any Loan Document with any person other than any Loan Party, and (e) release or substitute any Other Liable Party. For the purpose of this Section 7.5, “Other Liable Party” means any person, other than a Loan Party, who may now or may at any time hereafter be primarily or secondarily liable for any of the Obligations or who may now or may at any time hereafter have granted to the Administrative Agent a security interest in or Lien upon any property as security for the Obligations.

Section 7.6Exercise of Remedies. The provisions of this Section 7.6 shall apply and control to the extent of any inconsistency with any other provision in the Loan Documents.

(a)Subject to the provisions of this Section 7.6, (i) the Administrative Agent shall have all rights and remedies set forth in the Loan Documents and all rights and remedies which the Administrative Agent has been granted at any time under any other agreement or contract and all of the rights which the Administrative Agent has (or the holders have) under any law, statute, rule or regulation (each, a “Remedy” and collectively, “Remedies”) and (ii) the Administrative Agent shall be entitled to enforce such Remedies specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of the Loan Documents and to exercise all other rights granted by law, statute, rule or regulation. No Remedy is intended to be exclusive of any other Remedy, and each and every such Remedy shall be cumulative and shall be in addition to every other Remedy given or now or hereafter existing at law or in equity or by statute or otherwise.

(b)Any and all proceeds of any enforcement action or other payments pursuant to any of the Loan Documents received by the Administrative Agent shall be applied as set forth in Section 7.3.

ARTICLE VIII

THE ADMINISTRATIVE AGENT

Section 8.1Appointment and Authorization of Administrative Agent.

(a)Each of the Lenders hereby irrevocably appoints, designates and authorizes CF Global Credit, LP to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article VIII are solely for the benefit of the Administrative Agent and the Lenders, and neither Debtor nor any other Loan Party shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable Requirement of Law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

(b)The Administrative Agent shall also act as the “collateral agent” under the Loan Documents, and each of the Lenders hereby irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Administrative Agent, as “collateral agent” and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to Section 8.5 for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Loan Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent, shall be entitled to the benefits of all provisions of this Article VIII and Article IX (including Section 9.9(c), as though such co-agents, sub-agents and attorneys-in-fact were the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto.

(c)The Administrative Agent declares that it shall hold all Liens or Collateral governed by English law on trust for each of the Lenders on the terms contained in this Agreement. The rights, powers, authorities and discretions given to the Administrative Agent under or in connection with the Loan Documents shall be supplemental to the Trustee Act 1925 (United Kingdom) and the Trustee Act 2000 (United Kingdom) and in addition to any which may be vested in the Administrative Agent by law or regulation or otherwise. Section 1 of the Trustee Act 2000 (United Kingdom) shall not apply to the duties of the Administrative Agent in relation to the trusts constituted by this Agreement. Where there are any inconsistencies between the Trustee Act 1925 (United Kingdom) or the Trustee Act 2000 (United Kingdom) and the provisions of this Agreement, the provisions of this Agreement shall, to the extent permitted by law and regulation, prevail and, in the case of any inconsistency with the Trustee Act 2000 (United Kingdom), the provisions of this Agreement shall constitute a restriction or exclusion for the purposes of the Trustee Act 2000 (United Kingdom).

Section 8.2Administrative Agent and its Affiliates. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of banking, trust, financial, advisory, underwriting or other business with any Loan Party or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders or to provide notice to or consent of the Lenders with respect thereto.

77

Section 8.3Exculpatory Provisions.

(a)The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent and its Related Parties:

(i)shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(ii)shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable Requirement of Law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law. If the Administrative Agent so requests, it shall first be indemnified to its satisfaction from the Lenders or Required Lenders, as applicable, against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. No provision of this Agreement or any other Loan Document or any agreement or instrument contemplated hereby or thereby, or the transactions contemplated hereby or thereby shall require the Administrative Agent to: (i) expend or risk its own funds or provide indemnities in the performance of any of its duties hereunder or the exercise of any of its rights or power or (ii) otherwise incur any financial liability in the performance of its duties or the exercise of any of its rights or powers; and

(iii)shall not, except as expressly set forth herein and in the other Loan Documents, have any duty or responsibility to disclose, and shall not be liable for the failure to disclose, any information relating to any Loan Party or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

(b)Neither the Administrative Agent nor any of its Related Parties shall be liable for any action taken or not taken by the Administrative Agent under or in connection with this Agreement or any other Loan Document or the transactions contemplated hereby or thereby (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary), or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Article VII and Section 9.2) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given in writing to a Responsible Officer of the Administrative Agent by Debtor or a Lender.

(c)Neither the Administrative Agent nor any of its Related Parties have any duty or obligation to any Lender or participant or any other Person to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default or to inspect the Collateral or other property (including, without limitation, the books and records) of any Person, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Loan Documents, (v) the value or the sufficiency of any Collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any

78

certificate prepared by any Loan Party in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral, or (vi) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

(d)The Administrative Agent may at any time request instructions from the Lenders with respect to any actions or approvals which by the terms of this Agreement or of any of the other Loan Documents the Administrative Agent is permitted or required to take or to grant, and if such instructions are promptly requested, the Administrative Agent shall be absolutely entitled to refrain from taking any action or to withhold any approval under any of the Loan Documents until it shall have received such instructions from the Required Lenders. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or refraining from acting under this Agreement or any of the other Loan Documents in accordance with the instructions of the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents). Before the Administrative Agent acts or refrains from acting, it may require an officer’s certificate and/or an opinion of counsel satisfactory to the Administrative Agent with respect to the proposed action or inaction at Debtor’s expense. The Administrative Agent shall not be liable for any action it takes or omits to take in good faith in reliance upon such certificate or opinion. Whenever in the administration of the Loan Documents the Administrative Agent shall deem it necessary or desirable that a matter be proved or established before taking or suffering or omitting to take any act under any Loan Document, such matter (unless other evidence in respect thereof is herein specifically prescribed) may, in the absence of gross negligence or bad faith on the part of the Administrative Agent, be deemed to be conclusively proved and established by an officers’ certificate delivered to the Administrative Agent, and such certificate, in the absence of gross negligence or bad faith on the part of the Administrative Agent, shall be full warrant to the Administrative Agent for any action taken, suffered or omitted to be taken by it under the Loan Documents upon the faith thereof. The Administrative Agent shall not be responsible or liable for any failure or delay in the performance of its obligations under this Agreement or the other Loan Documents arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including, without limitation, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics; riots; business interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; accidents; labor disputes; acts of civil or military authority and governmental action. In no event shall the Administrative Agent be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Administrative Agent has been advised of the likelihood of such loss or damage and regardless of the form of action. The Administrative Agent shall not be required to qualify in any jurisdiction in which it is not presently qualified to perform its obligations as Administrative Agent or to enforce any rights and remedies in any foreign jurisdiction. The Administrative Agent shall not be liable for any error of judgment made in good faith by a Responsible Officer of the Administrative Agent unless it shall be proved that the Administrative Agent was negligent in ascertaining the pertinent facts.

Section 8.4Reliance by the Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall be fully protected in relying and shall not incur any liability for relying upon, any notice, request, certificate, communication, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall be fully protected in relying and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for the Loan Parties), independent accountants and other experts selected by it, and shall not be liable for any action

79

taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. For purposes of determining compliance with the conditions specified in Section 5.1, each Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received notice from such Lender prior to the proposed Closing Date specifying its objections. Delivery of any reports, information and documents to the Administrative Agent is for informational purposes only and the Administrative Agent’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including Debtor’s compliance with any of its covenants hereunder.

Section 8.5Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article VIII shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent did not appoint such subagent with due care.

Section 8.6Resignation of Administrative Agent.

(a)Notice. The Administrative Agent may at any time give notice of its resignation to the Lenders and Debtor. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with Debtor, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to) on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b)Effect of Resignation. With effect from the Resignation Effective Date (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders under any of the Loan Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (ii) except for any indemnity payments or other amounts then owed to the retiring Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Administrative Agent (other than as provided in Section 2.11 and other than any rights to indemnity payments or other amounts owed to the retiring Administrative Agent as of the Resignation Effective Date), and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this Section 8.6). The fees payable by Debtor to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between Debtor and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article VIII and Section 9.9 shall continue in effect for the benefit of such retiring Administrative Agent,

80

its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them (i) while the retiring Administrative Agent was acting as Administrative Agent and (ii) after such resignation or removal for as long as any of them continues to act in any capacity hereunder or under the other Loan Documents, including, without limitation, (A) acting as collateral agent or otherwise holding any collateral security on behalf of any of the Lenders and (B) in respect of any actions taken in connection with transferring the agency to any successor Administrative Agent.

Section 8.7Non-Reliance on the Administrative Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Section 8.8No Other Duties. Anything herein to the contrary notwithstanding, none of the titles listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent or a Lender hereunder.

Section 8.9Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on Debtor) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a)to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent hereunder) allowed in such judicial proceeding; and

(b)to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent hereunder. Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any Plan of Reorganization affecting the Obligations or the rights of any Lender to authorize the Administrative Agent to vote in respect of the claim of any Lender or in any such proceeding.

81

Section 8.10Collateral and Guaranty Matters.

(a)Each of the Lenders irrevocably authorize the Administrative Agent, at its option and in its discretion,

(i)to automatically release any Lien on any asset or other property granted to or held by the Administrative Agent under any Loan Document (i) upon payment in full in cash of all Obligations (other than indemnification and other contingent obligations not then due and payable and as to which no claim has been made at such time), (ii) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted hereunder or under any other Loan Document, or (iii) if approved, authorized or ratified in writing by the Required Lenders (or each Lender, as applicable) in accordance with Section 9.2;

(ii)to subordinate any Lien on any asset or other property granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien on such property that is permitted by Section 4.3(e); and

(iii)to release any Guarantor from its obligations under the Guaranty if such Person ceases to be a Subsidiary or becomes an Excluded Subsidiary as a result of a transaction permitted under the Loan Documents.

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty pursuant to this Section 8.10. In each case as specified in this Section 8.10, the Administrative Agent will, at Debtor’s expense, execute and deliver to the applicable Loan Party such documents as such Loan Party may reasonably request to evidence the release of such item of Collateral from the assignment and security interest granted under the Loan Documents or to subordinate its interest in such item, or to release such Guarantor from its obligations under the Guaranty, in each case in accordance with the terms of the Loan Documents and this Section 8.10; provided, however, that (i) the Administrative Agent shall not be required to execute any such document on terms which, in the Administrative Agent’s opinion, would expose the Administrative Agent to liability or create any obligations or entail any consequence other than the release of such Liens or Guarantors or the subordination of such items without representation, recourse or warranty, and (ii) such release or subordination shall not in any manner discharge, affect or impair the Obligations or any Lien upon (or obligations of any Loan Party in respect of) all interests in the Collateral retained by any Loan Party. The Administrative Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent’s Lien thereon, or any certificate prepared by any Loan Party in connection therewith, nor shall the Administrative Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral.

(b)The Administrative Agent shall have no obligation whatsoever to any Lender to assure that the Collateral exists or is owned by the Loan Parties or is cared for, protected or insured or has been encumbered or that the Lien granted to the Administrative Agent pursuant to this Agreement or any other Loan Document has been properly or sufficiently or lawfully created, perfected, protected or enforced or is entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity, or to continue exercising, any of the rights, authorities and powers granted or available to the Administrative Agent in this Section 8.8 or in any other Loan Document, it being understood and agreed that in respect of the Collateral, or any act, omission or event related thereto, the Administrative Agent may act in any manner it may deem appropriate, in its sole discretion, given the Administrative Agent’s own interest in the Collateral as one of the Lenders, if applicable, and that the Administrative Agent shall have no duty or liability whatsoever to any other Lender, except as otherwise provided herein.

82

(c)Beyond the exercise of reasonable care in the custody thereof, the Administrative Agent shall not have any duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to preservation of rights against prior parties or any other rights pertaining thereto. Debtor shall be responsible for providing, maintaining, monitoring or preserving insurance on or the payment of taxes with respect to any of the Collateral to the extent required by and in accordance with the terms of this Agreement. The Administrative Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property and shall not be liable or responsible for any loss or diminution in the value of any of the Collateral, by reason of the act or omission of any carrier, forwarding agency or other agent or bailee selected by the Administrative Agent in good faith, except (in each case) for its own gross negligence or willful misconduct as determined by a final and non-appealable decision of a court of competent jurisdiction.

(d)The Administrative Agent shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Liens in any of the Collateral, whether impaired by operation of law or by reason of any of any action or omission to act on its part hereunder, except to the extent such action or omission constitutes gross negligence or willful misconduct on the part of the Administrative Agent (as determined by a final, nonappealable judgment by a court of competent jurisdiction), for the validity or sufficiency of the Collateral or any agreement or assignment contained therein, for the validity of the title to the Collateral, for insuring the Collateral or for the payment of taxes, charges, assessments or Liens upon the Collateral or otherwise as to the maintenance of the Collateral. The Administrative Agent hereby disclaims any representation or warranty to the present and future holders of the Obligations concerning the perfection of the Liens granted hereunder or in the value of any of the Collateral.

(e)In the event that the Administrative Agent is required to acquire title to an asset for any reason, or take any managerial action of any kind in regard thereto, in order to carry out any fiduciary or trust obligation for the benefit of another, which in the Administrative Agent’s sole discretion may cause the Administrative Agent, to be considered an “owner or operator” under any Environmental Laws or otherwise cause the Administrative Agent to incur, or be exposed to, any environmental liability or any liability under any other federal, state or local law, the Administrative Agent reserves the right, instead of taking such action, either to resign as Administrative Agent or to arrange for the transfer of the title or control of the asset to a court appointed receiver. The Administrative Agent will not be liable to any Person for any Environmental Liabilities and Costs or any environmental liabilities or contribution actions under any federal, state or local law, rule or regulation by reason of the Administrative Agent’s actions and conduct as authorized, empowered and directed hereunder or relating to any kind of discharge or Release or threatened discharge or Release of any Hazardous Materials into the environment.

Section 8.11Lender ERISA Representation.

(a)Each Lender (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent and not, for the avoidance of doubt, to or for the benefit of Debtor or any other Loan Party, that at least one of the following is and will be true:

(i)such Lender is not using “plan assets” (within the meaning of Section 3(42) of ERISA or otherwise) of one or more Benefit Plans with respect to such Lender’s entrance into, participation in, administration of and performance of the Loans or this Agreement,

83

(ii)the transaction exemption set forth in one or more PTEs, such as PTE 84-14 (a class exemption for certain transactions determined by independent qualified professional asset managers), PTE 95-60 (a class exemption for certain transactions involving insurance company general accounts), PTE 90-1 (a class exemption for certain transactions involving insurance company pooled separate accounts), PTE 91-38 (a class exemption for certain transactions involving bank collective investment funds) or PTE 96-23 (a class exemption for certain transactions determined by in-house asset managers), is applicable with respect to such Lender’s entrance into, participation in, administration of and performance of the Loans and this Agreement,

(iii)(A) such Lender is an investment fund managed by a “Qualified Professional Asset Manager” (within the meaning of Part VI of PTE 84-14), (B) such Qualified Professional Asset Manager made the investment decision on behalf of such Lender to enter into, participate in, administer and perform the Loans and this Agreement, (C) the entrance into, participation in, administration of and performance of the Loans, the Term Loan Commitments and this Agreement satisfies the requirements of sub-sections (b) through (g) of Part I of PTE 84-14 and (D) to the best knowledge of such Lender, the requirements of subsection (a) of Part I of PTE 84-14 are satisfied with respect to such Lender’s entrance into, participation in, administration of and performance of the Loans and this Agreement, or

(iv)such other representation, warranty and covenant as may be agreed in writing between the Administrative Agent, in its sole discretion, and such Lender.

(b)In addition, unless either (1) sub-clause (i) in the immediately preceding clause (a) is true with respect to a Lender or (2) a Lender has provided another representation, warranty and covenant in accordance with sub-clause (iv) in the immediately preceding clause (a), such Lender further (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent and not, for the avoidance of doubt, to or for the benefit of Debtor or any other Loan Party, that the Administrative Agent is not a fiduciary with respect to the assets of such Lender involved in such Lender’s entrance into, participation in, administration of and performance of the Loans and this Agreement (including in connection with the reservation or exercise of any rights by the Administrative Agent under this Agreement, any other Loan Document or any documents related hereto or thereto).

Section 8.12Indemnification. To the extent that the Administrative Agent is not reimbursed and indemnified by any Loan Party, and whether or not the Administrative Agent has made demand on any Loan Party for the same, the Lenders will, upon written demand by the Administrative Agent (and, with respect to any Affected Financial Institution, such amounts shall be deemed due and payable no later than six days after demand therefor), reimburse the Administrative Agent for and indemnify the Administrative Agent from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, charges, expenses (including, without limitation, client charges and reasonable and documented out-of-pocket expenses of counsel or any other advisor to the Administrative Agent), advances or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or any of the other Loan Documents or any action taken or omitted by the Administrative Agent under this Agreement or any of the other Loan Documents, in proportion to each Lender’s Pro Rata Share, including, without limitation, advances and disbursements made pursuant to Section 8.10; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, advances or disbursements for which there has been a final non-appealable judicial determination that such liability resulted from the Administrative Agent’s gross negligence or willful misconduct. The obligations of the Lenders under this Section 8.12 shall survive the payment in full of the Loans, the resignation or removal of the Administrative Agent, and the termination of this Agreement and the exercise of Write-Down and Conversion Powers by an EEA Resolution Authority with respect to any Lender that is an Affected Financial Institution.

or to such other address or to the attention of such other individual as hereafter shall be designated in writing by the applicable party sent in accordance herewith; provided that an email copy of any notice, consent, approval, request or communication shall also be delivered to the Administrative Agent and the Lenders as specified above in the case of clauses (a), (b) or (c) of this Section 9.1. Any such notice or communication shall be deemed to have been given either at the time of personal delivery or, in the case of delivery service or mail, as of the date of first attempted delivery at the address and in the manner provided herein, or in the case of email, upon receipt of confirmation of electronic delivery. The Administrative Agent shall have the right to accept and act upon instructions, including funds transfer instructions (“Instructions”) given pursuant to this Agreement and sent by unsecured e-mail, pdf or other similar unsecured electronic methods. If Debtor elects to give any Instructions to the Administrative Agent using e-mail instructions (or instructions by a similar electronic method) and the Administrative Agent in its discretion elects to act upon such Instructions, the Administrative Agent’s understanding of such Instructions shall be deemed controlling. Debtor understands and agrees that the Administrative Agent cannot determine the identity of the actual sender of such Instructions and that the Administrative Agent shall conclusively presume that directions that purport to have been sent by an authorized officer listed on the incumbency certificate provided to the Administrative Agent have been sent by such authorized officer. Debtor shall be responsible for ensuring that only authorized officers transmit such Instructions to the Administrative Agent and that Debtor and all authorized officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by Debtor. The Administrative Agent shall not be liable for any losses, costs or expenses arising directly or indirectly from the Administrative Agent’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. Debtor agrees: (i) to assume all risks arising out of the use of e-mail instructions (or instructions by a similar electronic method) to submit Instructions to the Administrative

86

Agent, including without limitation the risk of the Administrative Agent acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Administrative Agent and that there may be more secure methods of transmitting Instructions than the method(s) selected by Debtor; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Administrative Agent immediately upon learning of any compromise or unauthorized use of the security procedure.

Section 9.2Amendments.

(a)Except as otherwise set forth in this Agreement (including Section 2.16), no amendment or waiver of any provision of this Agreement or any other Loan Document, and no consent to any departure by any Loan Party therefrom, shall in any event be effective unless the same shall be in writing and signed (x) in the case of an amendment, consent or waiver to cure any ambiguity, omission, defect or inconsistency or granting a new Lien for the benefit of the Administrative Agent and the other Secured Parties or extending an existing Lien over additional property, by the Administrative Agent and Debtor, (y) in the case of any other waiver or consent, by the Required Lenders (or by the Administrative Agent with the written consent of the Required Lenders) and (z) in the case of any other amendment, by the Required Lenders (or by the Administrative Agent with the written consent of the Required Lenders) and Debtor, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall:

(i)increase the Term Loan Commitment of any Lender, reduce the principal of, or interest on, the Loans payable to any Lender (it being understood that a waiver of any condition precedent set forth in Section 5.1, the waiver of (or amendment to the terms of) any mandatory prepayment of the Loans or mandatory prepayment or mandatory reduction of any Term Loan Commitments or any Default or Event of Default shall not constitute such an increase), reduce the amount of any fee payable for the account of any Lender, or postpone or extend any scheduled date fixed for any payment of principal of, or interest or fees on, the Loans payable to any Lender (it being understood that the waiver of (or amendment to the terms of) any mandatory prepayment of the Loans or mandatory prepayment or mandatory reduction of any Term Loan Commitments or any obligation of Debtor to pay default rate interest or any Default or Event of Default, shall not constitute such a postponement of any date scheduled for the payment of principal or interest), in each case, without the written consent of such Lender;

(ii)change the percentage of the Term Loan Commitments or of the aggregate unpaid principal amount of the Loans that is required for the Lenders or any of them to take any action hereunder without the written consent of each Lender;

(iii)amend the definition of “Required Lenders” or “Pro Rata Share” without the written consent of each Lender;

(iv)release all or a substantially all of the Collateral (except as otherwise provided in this Agreement and the other Loan Documents), subordinate any Lien granted in favor of the Administrative Agent for the benefit of the Administrative Agent and the Lenders, or release any Guarantor, in each case, without the written consent of each Lender; or

(v)amend, modify or waive Section 2.8 (other than Section 2.8(a)) or this Section 9.2 of this Agreement without the written consent of each Lender.

87

(b)Notwithstanding the foregoing, (A) no amendment, waiver or consent shall, unless in writing and signed by the Administrative Agent, affect the rights or duties of the Administrative Agent under this Agreement or the other Loan Documents and (B) any amendment, waiver or consent to any provision of this Agreement (including Section 2.8) that permits any Loan Party (or equity holder of a Loan Party) or any of their respective Affiliates to purchase Loans, become an eligible assignee pursuant to Section 9.7 and/or make offers to make optional prepayments on a non-pro rata basis shall require the prior written consent of the Required Lenders rather than the prior written consent of each Lender directly affected thereby.

(c)If any action to be taken by the Lenders hereunder requires the consent, authorization, or agreement of all of the Lenders or any Lender affected thereby, and a Lender (other than the Administrative Agent and its respective Affiliates and Related Funds) (the “Holdout Lender”) fails to give its consent, authorization, or agreement, then Debtor, upon at least five (5) Business Days prior irrevocable notice to the Holdout Lender, may permanently replace the Holdout Lender with one or more substitute lenders (each, a “Replacement Lender”), and the Holdout Lender shall have no right to refuse to be replaced hereunder. Such notice to replace the Holdout Lender shall specify an effective date for such replacement, which date shall not be later than fifteen (15) Business Days after the date such notice is given. Prior to the effective date of such replacement, the Holdout Lender and each Replacement Lender shall execute and deliver an Assignment and Acceptance, subject only to the Holdout Lender being repaid its share of the outstanding Obligations without any premium or penalty of any kind whatsoever;provided that if the Holdout Lender is replaced pursuant to this Section 9.2(c) due to its refusal to consent to the reduction or postponement of the Prepayment Premium payable under Section 2.6(g), upon such replacement, the Prepayment Premium that would have been payable to the Holdout Lender will be paid to the Holdout Lender. If the Holdout Lender shall refuse or fail to execute and deliver any such Assignment and Acceptance prior to the effective date of such replacement, the Holdout Lender shall be deemed to have executed and delivered such Assignment and Acceptance. The replacement of any Holdout Lender shall be made in accordance with the terms of Section 9.7. Until such time as the Replacement Lenders shall have acquired all of the Obligations, the Term Loan Commitments, and the other rights and obligations of the Holdout Lender hereunder and under the other Loan Documents, the Holdout Lender shall remain obligated to make its Pro Rata Share of Loans.

Section 9.3Preservation of Rights. Neither any failure nor any delay on the part of the Administrative Agent in insisting upon strict performance of any term, condition, covenant or agreement, or exercising any right, power, remedy or privilege hereunder, or under any Term Notes or under any other Loan Document, or any other instrument given as security therefor, shall operate as or constitute a waiver thereof, nor shall a single or partial exercise thereof preclude any other future exercise, or the exercise of any other right, power, remedy or privilege. In particular, and not by way of limitation, by accepting payment after the due date of any amount payable under this Agreement or any other Loan Document, the Administrative Agent shall not be deemed to have waived any right either to require prompt payment when due of all other amounts due under this Agreement or the other Loan Documents, or to declare a default for failure to effect prompt payment of any such other amount. Neither the execution nor the delivery of this Agreement shall in any manner impair or affect any other security for the Obligations. The rights and remedies of the Administrative Agent and the Lenders under this Agreement and the other Loan Documents shall be cumulative, and the exercise or partial exercise of any such right or remedy shall not preclude the exercise of any other right or remedy.

Section 9.4Unenforceability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or invalidity without invalidating the remaining portions hereof or thereof or affecting the validity or enforceability of such provision in any other jurisdiction.

88

Section 9.5Binding Effect and Assignment. This Agreement creates a continuing security interest in the Collateral of the Domestic Loan Parties (subject to applicable Legal Reservations) and (a) shall be binding on Debtor and its successors and permitted assigns and (b) shall inure, together with all rights and remedies of the Lenders hereunder, to the benefit of the Lenders and their respective successors and permitted assigns. None of the rights or duties of Debtor hereunder may be assigned or otherwise transferred without the prior written consent of the Administrative Agent and the Lenders except as provided herein.

Section 9.6Termination; Release.

(a)Upon the satisfaction in full of the Obligations (other than any indemnification and other contingent obligations not then due and payable and as to which no claim has been made at such time), this Agreement and the other Loan Documents and the security interest created hereby and thereby shall automatically terminate and all rights to the Collateral shall revert to Debtor. Upon such termination, the Administrative Agent will promptly, upon Debtor’s request and at Debtor’s expense, (a) return to Debtor such of the Collateral as shall not have been sold or otherwise disposed of or applied pursuant to the terms hereof; and (b) file, execute and deliver to Debtor such documents (in form and substance reasonably acceptable to the Administrative Agent) as Debtor shall reasonably request to evidence such termination; and

(b)Notwithstanding anything to the contrary contained herein or in any other Loan Document, the Administrative Agent is hereby irrevocably authorized by each Lender (without requirement of notice to or consent of any Lender except as expressly required by Section 9.2) to take, and the Administrative Agent, hereby agrees, subject to Section 8.10 hereof, to take promptly any action requested by Debtor having the effect of releasing, or evidencing the release of any Collateral or Guarantor (i) to the extent necessary to permit consummation of any transaction not prohibited by any Loan Document or that has been consented to in accordance with Section 9.2 or (ii) under the circumstances described in clause (a) above.

Section 9.7Successors and Assigns.

(a)This Agreement and the other Loan Documents shall be binding upon and inure to the benefit of each Loan Party and the Administrative Agent and each Lender and their respective successors and assigns; provided, however, that none of the Loan Parties may assign or transfer any of their rights hereunder or under the other Loan Documents without the prior written consent of the Administrative Agent and each Lender and any such assignment without the Lenders’ prior written consent shall be null and void.

(b)Subject to the conditions set forth in clause (c) below, each Lender may assign to one or more other Lenders or other entities, other than Disqualified Lenders, all or a portion of its rights and obligations under this Agreement with respect to all or a portion of its Term Loan Commitment and any Loan made by it:

(i)such assignment to be acknowledged by the Administrative Agent; provided, however, that no such acknowledgment of the Administrative Agent shall be required (A) in connection with any assignment by a Lender to a Lender, an Affiliate of such Lender or a Related Fund of such Lender or (B) if such assignment is in connection with any merger, consolidation, sale, transfer, or other disposition of all or any substantial portion of the business or loan portfolio of such Lender; and

89

(ii)with the consent of Debtor; provided, however, that no written consent of Debtor shall be required (A) in connection with any assignment by a Lender to a Lender, an Affiliate of such Lender or a Related Fund of such Lender or (B) with respect to any Person other than a Disqualified Lender, at any time that an Event of Default shall have occurred and be continuing; provided, further, that Debtor shall be deemed to have consented to any assignment unless it has objected thereto by delivering written notice (which may be in the form of an email) to the Administrative Agent within ten (10) Business Days after receipt of any request for such consent or such assignment is to a Disqualified Lender.

(c)Assignments shall be subject to the following additional conditions:

(i)Each such assignment shall be in an amount which is at least $1,000,000 or an integral multiple of $1,000,000 in excess thereof (or the remainder of such Lender’s Term Loan Commitment) (except such minimum amount shall not apply to an assignment by a Lender to (A) a Lender, an Affiliate of such Lender or a Related Fund of such Lender or (B) a group of new Lenders, each of whom is an Affiliate or Related Fund of each other to the extent the aggregate amount to be assigned to all such new Lenders is at least $1,000,000 or an integral multiple of $1,000,000 in excess thereof (or the remainder of such Lender’s Term Loan Commitment));

(ii)The parties to each such assignment shall execute and deliver to the Administrative Agent for its acceptance an Assignment and Acceptance, together with any promissory note subject to such assignment and all documentation and other information with respect to the assignee that is required by regulatory authorities under applicable “know your customer” and anti-money laundering rules and regulations, including the USA PATRIOT Act, such parties shall deliver to the Administrative Agent, for the benefit of the Administrative Agent, a processing and recordation fee of $3,500 (except the payment of such fee shall not be required in connection with an assignment by a Lender to a Lender, an Affiliate of such Lender or a Related Fund of such Lender); and

(iii)No such assignment shall be made to any Loan Party or any of its Affiliates (other than the Lenders on the Closing Date or any of their Affiliates).

(d)Upon such execution, delivery and acceptance, from and after the effective date specified in each Assignment and Acceptance and recordation on the Register, which effective date shall be at least three (3) Business Days after the delivery thereof to the Administrative Agent (or such shorter period as shall be agreed to by the Administrative Agent and the parties to such assignment), (A) the assignee thereunder shall become a “Lender” hereunder and, in addition to the rights and obligations hereunder held by it immediately prior to such effective date, have the rights and obligations hereunder that have been assigned to it pursuant to such Assignment and Acceptance and (B) the assigning Lender thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto).

(e)By executing and delivering an Assignment and Acceptance, the assigning Lender and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Acceptance, the assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or any other Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other Loan Document furnished pursuant hereto; (ii) the assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Loan Party or any of its Subsidiaries or the performance or observance by any Loan Party of any of its obligations under this Agreement or any other Loan Document furnished pursuant hereto; (iii) such assignee confirms that it has

90

received a copy of this Agreement and the other Loan Documents, together with such other documents and information it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the assigning Lender, the Administrative Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents; (v) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to the Administrative Agent by the terms hereof and thereof, together with such powers as are reasonably incidental hereto and thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement and the other Loan Documents are required to be performed by it as a Lender.

(f)The Administrative Agent shall, acting solely for this purpose as an agent of Debtor, maintain, or cause to be maintained at the Payment Office, a copy of each Assignment and Acceptance delivered to and accepted by it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Term Loan Commitments of, and the principal amount of the Loans (and stated interest thereon) owing to each Lender from time to time. The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and Debtor, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by Debtor and any Lender at any reasonable time and from time to time upon reasonable prior notice.

(g)Upon receipt by the Administrative Agent of a completed Assignment and Acceptance, and subject to the acknowledgment required from the Administrative Agent pursuant to Section 9.7(b)(i) (which acknowledgment must be evidenced by the Administrative Agent’s execution of an acceptance to such Assignment and Acceptance), the Administrative Agent shall accept such assignment, record the information contained therein in the Register (as adjusted to reflect any principal payments on or amounts capitalized and added to the principal balance of the Loans and/or Term Loan Commitment reductions made subsequent to the effective date of the applicable assignment, as confirmed in writing by the corresponding assignor and assignee in conjunction with delivery of the assignment to the Administrative Agent) and provide to the Administrative Agent a copy of the fully executed Assignment and Acceptance.

(h)A Loan (and the note, if any, evidencing the same) may be assigned or sold in whole or in part only by registration of such assignment or sale on the Register (and each note shall expressly so provide). Any assignment or sale of all or part of such Loan (and the note, if any, evidencing the same) may be effected only by registration of such assignment or sale on the Register, together with the surrender of the note, if any, evidencing the same duly endorsed by (or accompanied by a written instrument of assignment or sale duly executed by) the holder of such note, whereupon, at the request of the designated assignee(s), one or more new notes in the same aggregate principal amount shall be issued to the designated assignee(s). Prior to the registration of assignment or sale of any Loan (and the note, if any, evidencing the same), the Administrative Agent shall treat the Person in whose name such Loan (and the note, if any, evidencing the same) is registered on the Register as the owner thereof for the purpose of receiving all payments thereon, notwithstanding notice to the contrary.

(i)In the event that any Lender sells participations in a Loan, such Lender shall, acting for this purpose as a non-fiduciary agent on behalf of Debtor, maintain, or cause to be maintained, a register, on which it enters the name of all participants in the Loans held by it and the principal amount (and stated interest thereon) of the portion of the Loan that is the subject of the participation (the “Participant Register”). A Loan (and the note, if any, evidencing the same) may be participated in whole or in part only by registration of such participation on the Participant Register (and each note shall expressly so provide). Any participation of such Loan (and the note, if any, evidencing the same) may be effected only by the registration of such participation on the Participant Register. The Participant Register

91

shall be available for inspection by Debtor and any Lender at any reasonable time and from time to time upon reasonable prior notice. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

(j)Any Non-U.S. Lender who purchases or is assigned or participates in any portion of such Loan shall comply with Section 2.11(d).

(k)Each Lender may sell participations to one or more banks or other entities, other than Disqualified Lenders, in or to all or a portion of its rights and obligations under this Agreement and the other Loan Documents (including, without limitation, all or a portion of its Term Loan Commitments and the Loans made by it); provided, that (i) such Lender’s obligations under this Agreement (including without limitation, its Term Loan Commitments hereunder) and the other Loan Documents shall remain unchanged; (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and Debtor, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents; and (iii) a participant shall not be entitled to require such Lender to take or omit to take any action hereunder except (A) action directly effecting an extension of the maturity dates or decrease in the principal amount of the Loans (it being understood that the waiver of (or amendment to the terms of) any mandatory prepayment of the Loans or mandatory prepayment or mandatory reduction of any Term Loan Commitments or any Default or Event of Default shall not constitute such a decrease in the principal amount of the Loans), (B) action directly effecting an extension of the due dates or a decrease in the rate of interest payable on the Loans or the fees payable under this Agreement (it being understood that the waiver of (or amendment to the terms of) any mandatory prepayment of the Loans or mandatory prepayment or mandatory reduction of any Term Loan Commitments or any obligation of Debtor to pay default rate interest or any Default or Event of Default, shall not constitute such an extension of due dates or decrease in the rate of interest), or (C) actions directly effecting a release of all or substantially all of the Collateral or any Guarantor (except as set forth in Section 8.10 of this Agreement or any other Loan Document). The Loan Parties agree that each participant shall be entitled to the benefits of Section 2.11 and Section 2.12 of this Agreement with respect to its participation in any portion of the Term Loan Commitments and the Loans as if it was a Lender; provided, that such participant agrees to be subject to the provisions of Section 2.15 as if it were an assignee under Section 9.7(b) and that such participant shall not be entitled to receive any greater payment under Section 2.11 or 2.12, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the participant acquired the applicable participation.

Section 9.8Renewal, Extension or Rearrangement. All provisions of this Agreement relating to the Term Notes shall apply with equal force and effect to each and all promissory notes or security instruments hereinafter executed which in whole or in part represent a renewal, extension for any period, increase or rearrangement of any part of the Term Notes.

Section 9.9Expenses; Indemnification.

Section 9.16Counterparts. This Agreement may be executed by one or more of the parties hereto on any number of separate counterparts (including by pdf transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

Section 9.17Headings. The Article and Section headings in this Agreement are included herein for convenience of reference only and shall not constitute a part of this Agreement for any other purpose.

Section 9.18Preferences. The Administrative Agent shall have the continuing and exclusive right to apply or reverse and reapply any and all payments by Debtor to any portion of the Obligations of Debtor hereunder. To the extent Debtor makes a payment or payments to the Administrative Agent, which payment or proceeds or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or proceeds received, the Obligations hereunder or part thereof intended to be satisfied shall be revived and continue in full force and effect, as if such payment or proceeds had not been received by the Administrative Agent. The foregoing is without limitation of the rights in favor of the Administrative Agent set forth in Article VIII.

Section 9.19Waiver of Notice. Debtor shall not be entitled to any notices of any nature whatsoever from the Administrative Agent except with respect to matters for which this Agreement or the other Loan Documents specifically and expressly provide for the giving of notice by the Administrative Agent to Debtor and except with respect to matters for which Debtor is not, pursuant to applicable law, permitted to waive the giving of notice. Debtor hereby expressly waives the right to receive any notice from the Administrative Agent with respect to any matter for which this Agreement or the other Loan Documents do not specifically and expressly provide for the giving of notice by the Administrative Agent to Debtor.

96

Section 9.20Exhibits and Schedules Incorporated. The Exhibits and Schedules annexed hereto are hereby incorporated herein as a part of this Agreement with the same effect as if set forth in the body hereof.

Section 9.21Waiver of Marshaling of Assets. To the fullest extent Debtor may legally do so, Debtor waives all rights to a marshalling of the assets of Debtor, its owners, if any, and others with interests in such Person, or to a sale in inverse order of alienation in the event of foreclosure of the interests hereby created, and agrees not to assert any right under any laws pertaining to the marshalling of assets, the sale in inverse order of alienation, homestead exemption, the administration of estates of decedents, or any other matters whatsoever to defeat, reduce or affect the right of the Administrative Agent under the Loan Documents to a sale of the Collateral for the collection of the Indebtedness evidenced hereby without any prior or different resort for collection, of the right of the Administrative Agent to the payment of the Indebtedness evidenced hereby out of the Net Cash Proceeds of the Collateral or any interest therein in preference to every other claimant whatsoever. In addition, Debtor, for itself and its successors and assigns, waives in the event of foreclosure of any or all of the Liens, any equitable right otherwise available to such Debtor which would require the separate sale of the Collateral or require the Administrative Agent to exhaust its remedies against any part of the Collateral before proceeding against any other part or parts thereof; and further in the event of such foreclosure Debtor does hereby expressly consent to and authorize, at the option of the Administrative Agent (acting at the written direction of the Required Lenders), the foreclosure and sale either separately or together of any or all of the Collateral.

In the event of any conflict between the provisions of this Agreement and any of the other Loan Documents, the provisions of this Agreement shall control. The parties hereto acknowledge that they were represented by counsel in connection with the negotiation and drafting of the Loan Documents and that such Loan Documents shall not be subject to the principle of construing their meaning against the party which drafted same. In case any provision in or obligation hereunder or under any other of the Loan Documents shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or such provision or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby. All covenants hereunder shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations of, another covenant shall not avoid the occurrence of an Event of Default if such action is taken or condition exists.

Section 9.23Brokers and Financial Advisors. Each of the Administrative Agent and Debtor hereby represent that it has dealt with no financial advisors, brokers, underwriters, placement agents, lenders or finders in connection with the transactions contemplated by this Agreement.

97

Section 9.25No Third Party Beneficiaries. Except as otherwise provided in Section 9.27 hereof, this Agreement and the other Loan Documents are solely for the benefit of Debtor and the Lenders (including Affiliates of the Lenders), and nothing contained in this Agreement or the other Loan Documents shall be deemed to confer upon anyone other than such Persons any right to insist upon or to enforce the performance or observance of any of the obligations contained herein or therein. All conditions to the obligations of the issuance of the Loan hereunder are imposed solely and exclusively for the benefit of the Lenders and their Affiliates, and no other Person shall have standing to require satisfaction of such conditions in accordance with their terms or be entitled to assume that the Lenders will refuse to issue all or any portion of the Loan in the absence of strict compliance with any or all thereof and no other Person shall under any circumstances be deemed to be a beneficiary of such conditions, any or all of which may be freely waived in whole or in part by the Administrative Agent (acting at the written direction of the Required Lenders) if, in its sole discretion, it deems it advisable or desirable to do so.

Section 9.26No Reliance. Debtor acknowledges that it is not relying upon any person, firm or corporation, other than Debtor and its officers, directors, consultants and advisors in entering into the Loan. Debtor agrees that none of the Administrative Agent, the Lenders or any Affiliate of the Administrative Agent, Lenders or their respective controlling persons, officers, directors, partners, agents, or employees of any such person shall be liable to Debtor in connection with Debtor’s decision to enter into the Loan.

Section 9.27Benefitted Person. Wherever this Agreement provides for a covenant by Debtor in favor of the Administrative Agent, any Lender, any Lender Affiliate or their respective successors and/or assigns (the “Benefitted Persons”), each Benefitted Person is hereby expressly declared to be an intended third party beneficiary of such covenant and shall have the right to directly enforce such covenant against Debtor.

Section 9.28Other Services. Nothing in this Agreement will be deemed to restrict the Administrative Agent, any Lender or any of their respective Affiliates from providing services to Debtor or its Affiliates or earning fees and other compensation from Debtor or its Affiliates if otherwise permitted by law, including, without limitation, the IRC.

Section 9.29Acknowledgment and Consent to Bail-In of Affected Financial Institutions. Solely to the extent any Lender that is an Affected Financial Institution is a party to this Agreement and notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any Lender that is an Affected Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to the Write-Down and Conversion Powers of the applicable Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

(a)the application of any Write-Down and Conversion Powers by the applicable Resolution Authority to any such liabilities arising hereunder which may be payable to it by any Lender that is an Affected Financial Institution; and

ARTICLE X

CONTINUING GUARANTY

Section 10.1    Guaranty. Each Guarantor hereby absolutely and unconditionally, jointly and severally guarantees, as primary obligor and as a guaranty of payment and performance and not merely as a guaranty of collection, prompt payment when due, whether at stated maturity, by required prepayment, upon acceleration, demand or otherwise, and at all times thereafter, of any and all Obligations (for each Guarantor, subject to the proviso in this sentence, its “Guaranteed Obligations”); provided that the liability of each Guarantor individually with respect to this Guaranty shall be limited to an aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance under Section 548 of the Bankruptcy Code of the United States or any comparable provisions of any applicable state law. Without limiting the generality of the foregoing, the Guaranteed Obligations shall include any such indebtedness, obligations, and liabilities, or portion thereof, which may be or hereafter become unenforceable or compromised or shall be an allowed or disallowed claim under any proceeding or case commenced by or against any Guarantor under any Debtor Relief Laws. The Administrative Agent’s books and records showing the amount of the Obligations shall be admissible in evidence in any action or proceeding, and shall be binding upon each Guarantor, and conclusive for the purpose of establishing the amount of the Obligations. This Guaranty shall not be affected by the genuineness, validity, regularity or enforceability of the Obligations or any instrument or agreement evidencing any Obligations, or by the existence, validity, enforceability, perfection, non-perfection or extent of any collateral therefor, or by any fact or circumstance relating to the Obligations which might otherwise constitute a defense to the obligations of the Guarantors, or any of them, under this Guaranty, and each Guarantor hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating to any or all of the foregoing.

Section 10.2    Rights of Lenders. Each Guarantor consents and agrees that the Lenders may, at any time and from time to time, without notice or demand, and without affecting the enforceability or continuing effectiveness hereof: (a) amend, extend, renew, compromise, discharge, accelerate or otherwise change the time for payment or the terms of the Obligations or any part thereof; (b) take, hold, exchange, enforce, waive, release, fail to perfect, sell, or otherwise dispose of any security for the payment of this Guaranty or any Obligations; (c) apply such security and direct the order or manner of sale thereof as the Administrative Agent and the Lenders in their sole discretion may determine; and (d) release or substitute one or more of any endorsers or other guarantors of any of the Obligations. Without limiting the generality of the foregoing, each Guarantor consents to the taking of, or failure to take, any action which might in any manner or to any extent vary the risks of such Guarantor under this Guaranty or which, but for this provision, might operate as a discharge of such Guarantor.

Section 10.3    Certain Waivers. Each Guarantor waives (a) any defense arising by reason of any disability or other defense of Debtor or any other guarantor, or the cessation from any cause whatsoever (including any act or omission of the Administrative Agent or any Lender) of the liability of Debtor or any other Loan Party; (b) any defense based on any claim that such Guarantor’s obligations exceed or are more burdensome than those of Debtor or any other Loan Party; (c) the benefit of any statute of limitations affecting any Guarantor’s liability hereunder; (d) any right to proceed against Debtor or any other Loan Party, proceed against or exhaust any security for the Obligations, or pursue any other remedy in the power of the Administrative Agent or any Lender whatsoever; (e) any benefit of and any right to participate in any security now or hereafter held by the Administrative Agent or any Lender; and (f) to the fullest extent permitted by law, any and all other defenses (other than payment in full of the Obligations (other than any indemnification and other contingent obligations not then due and payable and as to which no claim has been made at such time)) or benefits that may be derived from or afforded by applicable Requirements of Law limiting the liability of or exonerating guarantors or sureties. Each Guarantor expressly waives all setoffs and counterclaims and all presentments, demands for payment or performance, notices of nonpayment or nonperformance, protests, notices of protest, notices of dishonor and all other notices or demands of any kind or nature whatsoever with respect to the Obligations, and all notices of acceptance of this Guaranty or of the existence, creation or incurrence of new or additional Obligations.

99

Section 10.4    Obligations Independent. The obligations of each Guarantor hereunder are those of primary obligor, and not merely as surety, and are independent of the Obligations and the obligations of any other guarantor, and a separate action may be brought against each Guarantor to enforce this Guaranty whether or not Debtor or any other person or entity is joined as a party.

Section 10.5    Subrogation. No Guarantor shall exercise any right of subrogation, contribution, indemnity, reimbursement or similar rights with respect to any payments it makes under this Guaranty until all of the Obligations and any amounts payable under this Guaranty have been indefeasibly paid and performed in full (other than any indemnification and other contingent obligations not then due and payable and as to which no claim has been made at such time) and the Loans are terminated. If any amounts are paid to a Guarantor in violation of the foregoing limitation, then such amounts shall be held in trust for the benefit of the holders of the Obligations and shall forthwith be paid to the holders of the Obligations to reduce the amount of the Obligations, whether matured or unmatured.

Section 10.6    Termination; Reinstatement. This Guaranty is a continuing and irrevocable guaranty of all Obligations now or hereafter existing and shall remain in full force and effect until the termination of the Term Loan Commitments and the repayment in full of the Obligations (other than any indemnification and other contingent obligations not then due and payable and as to which no claim has been made at such time). Notwithstanding the foregoing, this Guaranty shall continue in full force and effect or be revived, as the case may be, if any payment by or on behalf of Debtor or a Guarantor is made, or any of the holders of the Obligations exercises its right of setoff, in respect of the Obligations and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by any of the holders of the Obligations in their discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Laws or otherwise, all as if such payment had not been made or such setoff had not occurred and whether or not the Secured Parties are in possession of or have released this Guaranty and regardless of any prior revocation, rescission, termination or reduction. The obligations of each Guarantor under this Section 10.6 shall survive termination of this Guaranty.

Section 10.7    Stay of Acceleration. If acceleration of the time for payment of any of the Obligations is stayed, in connection with any case commenced by or against any Guarantor(s) or Debtor under any Debtor Relief Laws, or otherwise, all such amounts shall nonetheless be payable by any other Guarantor(s), jointly and severally, immediately upon demand by the holders of the Obligations.

Section 10.8    Condition of Debtor. Each Guarantor acknowledges and agrees that it has the sole responsibility for, and has adequate means of, obtaining from Debtor and any other guarantor such information concerning the financial condition, business and operations of Debtor and any such other guarantor as such Guarantor requires, and that none of the holders of the Obligations has any duty, and such Guarantor is not relying on the holders of the Obligations at any time, to disclose to it any information relating to the business, operations or financial condition of Debtor or any other guarantor (each Guarantor waiving any duty on the part of the holders of the Obligations to disclose such information and any defense relating to the failure to provide the same).

Section 10.9    Appointment of Debtor. Each of the Loan Parties hereby appoints Debtor to act as its agent for all purposes of this Agreement, the other Loan Documents and all other documents and electronic platforms entered into in connection herewith and agrees that (a) Debtor may execute such documents and provide such authorizations on behalf of such Loan Parties as Debtor deems appropriate in its sole discretion and each Loan Party shall be obligated by all of the terms of any such document and/or authorization executed on its behalf, (b) any notice or communication delivered by the Administrative Agent or a Lender to Debtor shall be deemed delivered to each Loan Party and (c) the Administrative Agent or the Lenders may accept, and be permitted to rely on, any document, authorization, instrument or agreement executed by Debtor on behalf of each of the Loan Parties.

Section 10.10    Right of Contribution. The Guarantors agree among themselves that, in connection with payments made hereunder, each Guarantor shall have contribution rights against the other Guarantors as permitted under applicable Requirements of Law.

100

Section 10.11    UK Local Law Limitations. For any Guarantors incorporated in England and Wales, this Guaranty does not apply to any liability to the extent that it would result in this Guaranty constituting unlawful financial assistance within the meaning of sections 678 or 679 of the Companies Act 2006.

Advanced Emissions Solutions Completes Acquisition of Arq Limited’s Business

Revised transaction structure results in ADES acquiring 100% of the equity interests of Arq Limited subsidiaries in exchange for issuance of preferred shares

Final ownership terms results in legacy ADES shareholders retaining 59% of the outstanding equity

GREENWOOD VILLAGE, Colorado, February 1, 2023 -GlobeNewswire - Advanced Emissions Solutions, Inc. (NASDAQ: ADES) (the “Company” or “ADES”), a leader in emissions control solutions for coal-fired power generation, industrial and municipal water purification markets, today closed its previously announced agreement with Arq Limited to combine their respective businesses on updated terms and structure.

“We are pleased to announce the completion of the acquisition of all of the subsidiaries of Arq Limited. As a result of changing macroeconomic conditions, the Board and management team of ADES reopened discussions with the leaders of Arq Limited and have revised the terms of the proposed transaction,” said Greg Marken, Chief Executive Officer, President and Treasurer of ADES. “As a result, the parties have mutually agreed upon a new deal structure that both parties believe are conducive to long-term value creation and sustainability for the combined company. All parties look forward to collaboratively forging the future for ADES and our shareholders.”

Updated Transaction Terms

•Pursuant to the revised securities purchase agreement, ADES issued a combination of shares of common stock and shares of a newly created series of preferred stock in exchange for all of the equity interests in all of the subsidiaries of Arq Limited (“Arq”).

•That new preferred shares will automatically convert to common stock upon the approval by ADES’ shareholders. Until conversion, the preferred security will accrue dividends at an 8% coupon rate (or if greater, the dividend paid on ADES common shares) that will be payable in cash or in kind, which coupon will increase at set intervals if the conversion is not approved within 635 days of closing.

•Prior to the impact of new capital, legacy ADES and Arq shareholders owned 67.9% and 32.1% of the combined company, respectively.

•The Company also closed on

◦a private placement of approximately $15.4 million of its common stock from certain significant Arq shareholders and members of Arq management at a price of $4.00 per share.

◦a $10.0 million term debt facility.

•The lender under the debt facility also obtained penny warrants to purchase 1% of the pro forma equity of the combined company.

•After giving effect to the PIPE investment and the warrants provided to the lenders, legacy ADES and Arq shareholders owned 59.2% and 28.0% of the Company, respectively while new PIPE investors and the lenders (assuming conversion of the warrants) owned 11.8% and 1.0% of the new Company respectively.

Marken added, “The acquisition of Arq marks an important step toward solidifying our future and delivering on our commitment to creating shareholder value. The combined Company, through the use of two base feedstocks, will be able to pursue end markets served by both Powder and Granular Activated Carbon products and will be the only completely vertically integrated North American activated carbon provider from feedstock to distribution.”

Marken concluded, “We believe this is the next step in building long-term growth through diversification of potential products and customers which will result in higher margin opportunities within the activated carbon market, as well as enabling access to additional potential revenue streams that our Company, without Arq, would not have been able to access. The capital that we will be installing, most of which will be at our Louisiana based facilities, enables the processing of bituminous based feedstock and decreases our long-term exposure to potential headwinds we would have otherwise faced within our power generation market. The result of this transaction is a truly differentiated environmental technology company with new growth avenues and a path toward long-term, sustainable profitability.”

Julian McIntyre, Founder and Chief Executive Officer of Arq Limited, added, "We are delighted to join-up with ADES. We face a growing, under-served market and the combination of our teams, capabilities and infrastructure allows us to offer an enhanced product portfolio with a competitive cost-base. We are optimistic about the long-term prospects for the business."

The Company has scheduled a special shareholder conference call to begin at 9:00 a.m. Eastern Time on Thursday, February 2, 2023, to discuss the revised terms of the acquisition.
