Until the expiration of the statute of limitations (including extensions) for assessment and collection of tax by the IRS with respect to tax returns filed by the Seller for each year of the Recapture Period, the Partner Counterparty shall not replace the Partner Guaranty or the Partner Guarantor without the Buyer’s prior written consent (such consent not to be unreasonably withheld, conditioned, or delayed), unless the following conditions are satisfied, in which case the consent of the Buyer shall not be required and the replacement guarantor shall be the successor to the Partner Guarantor that it has replaced hereunder:

(A)such replacement guarantor either (i) has a rating not less than “BBB” from S&P or “Baa2” from Moody’s or (ii) has a tangible net worth of at least five hundred million dollars ($500,000,000), calculated based on the most recent annual audited or quarterly unaudited financial statements of such replacement guarantor;

(B)such replacement guarantor becomes a party to the existing Partner Guaranty or delivers a replacement guaranty (i) in the same form as such Partner Guaranty or (ii) in such other form and on such other terms satisfactory to the Buyer;

(C)the Buyer has received at least ten Business Days’ prior notice of such replacement and all documentation and information requested by the Buyer to comply with the requirements of the USA PATRIOT Act of 2001 and all applicable “know your customer” rules and regulations and Anti-Corruption Laws;

(D)such replacement guarantor is an Affiliate of the Seller, and the Buyer shall have received evidence reasonably satisfactory to it showing the relationship between the Seller and such replacement guarantor; and

(E)the replacement guarantor provides a legal opinion in form and substance reasonably satisfactory to the Buyer covering enforceability of the replacement guaranty and certain related New York law matters substantially similar to the opinion letter delivered pursuant to clause (5)(a) of Schedule 2 and covering certain corporate matters substantially similar to the opinion letter delivered pursuant to clause (5b) or (5c), as applicable, of Schedule 2.

(xiv) Credit Trigger. If a Credit Trigger (as defined in the Partner Guaranty) has occurred, the Partner Counterparty will within twenty days provide a Replacement Guaranty or collateral security to Buyer in the form of cash or a letter of credit (from a financial institution rated at least “A3” from Moody’s and “A-” from S&P and in form and substance reasonably acceptable to Buyer). Such collateral security shall be in an amount equal to 150% of the Purchase Price (provided that the Purchase Price, for purposes of such calculation, shall be reduced by 20% upon the expiration of the statute of limitations (including extensions) for assessment and collection of tax by the IRS with respect to tax returns filed by the Seller for the first year of the Recapture Period, and then by an additional 20% each annual anniversary thereafter). The Parties agree that, upon a breach of this Section 5(b)(xiv) by the Partner Counterparty, the remedies at law of Buyer for such breach shall not be a sufficient remedy, that such breach would cause irreparable harm to Buyer, and that Buyer shall be entitled to specific performance of the obligation set forth in this Section 5(b)(xiv) to provide collateral security to Buyer, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or in equity. The Partner Counterparty hereby consents to specific performance as a remedy for any such breach and irrevocably waives any defense based on the adequacy of a remedy at law and any other defense that might be asserted to bar the remedy of specific performance in any action which may be brought with respect to this Section 5(b)(xiv).

(xv) Information Generally. During the Recapture Period and upon the reasonable request of the Buyer, the Partner Counterparty shall cause the Seller to provide the Buyer, within a reasonable time (not to exceed ten Business Days) after such request, with such additional information material to the operation of the Facility (other than any such information relating to the design of the Facility) as requested by the Buyer from time to time; provided, that such information is reasonably available to the Seller and the provision thereof to the Buyer would not result in a material burden to the Partner Counterparty or the Seller.

(xvi) Use of Proceeds. The Partner Counterparty shall not, and shall cause the Seller not to use the proceeds of the Purchase Price: (A) in furtherance in furtherance of an offer, payment, promise to pay, or authorization of the payment or giving of money, or anything else of value, to any Person in violation of Anti-Corruption Laws; (B) for the purpose of funding, financing or facilitating any activities, business or transaction of or with any Sanctioned Person, or in any Sanctioned Country, to the extent such activities, businesses or transaction would be prohibited by Sanctions if conducted by a corporation incorporated in the U.S.; or (C) in any manner that would result in the violation of any Sanctions applicable to Partner Counterparty or any Seller Party.

(xvii) Condemnation Events and Casualty Events. During the Recapture Period, if a Condemnation Event shall be threatened in writing or occur, or a Casualty Event shall occur with respect to any material portion of the Facility or the Facility Site, the Partner Counterparty shall cause the Seller Parties to (A) promptly upon discovery or receipt of notice of any such threat or occurrence provide written notice thereof to the Buyer; (B) diligently pursue all of its rights to compensation against the relevant Governmental Authority or insurer in respect of such event; (C) not, without the written consent of the Buyer, compromise or settle any claim against such Governmental Authority or insurer; and (D)

except to the extent restricted or otherwise governed by the terms of any Permitted Indebtedness, not distribute any eminent domain or insurance proceeds unless and until all amounts payable to Buyer hereunder resulting or reasonably likely to result from such event have been paid to the Buyer (or reserved in an escrow account for the benefit of the Buyer in an amount and subject to release conditions acceptable to the Buyer in its sole discretion); provided, however, that this clause (xvii) shall not prohibit or require any action (or inaction) that results in a Tax Credit Loss that is fully insured pursuant to the Tax Insurance Policy.

(xviii) Maintenance. The Partner Counterparty shall cause the Seller Parties to (A) maintain and preserve its existence as a limited liability company, in its respective jurisdiction of organization and all material rights, privileges and franchises necessary or desirable in the normal conduct of its business; (B) perform all of their material contractual obligations under the Material Project Documents and all other material agreements and contracts by which each is bound; (C) maintain its properties and assets in good repair and working order and condition in accordance with prudent industry practices; and (D) maintain in full force and effect all Required Governmental Approvals and any other material Governmental Approvals that are necessary and advisable to conduct its business and to own, insure, operate and maintain the Facility in the manner contemplated by the Material Project Documents, in each case except to the extent that the failure to comply with the foregoing that would not reasonably be expected to cause a recapture of the Transferred Tax Credits or cause Project to be considered to have been taken out of service for federal income tax purposes; provided, however, that this clause (xviii) shall not prohibit or require any action (or inaction) that results in a Tax Credit Loss that is fully insured pursuant to the Tax Insurance Policy.

(xix) Tax Insurance Policy. The Partner Counterparty shall and shall cause the Seller Parties (A) to promptly notify the Buyer of any correspondence received from the insurer under the Tax Insurance Policy, (B) use best efforts to assist the Buyer in its efforts to comply with the terms and conditions of the Tax Insurance Policy, and (C) not to take any action, or fail to take any action, that could cause any loss of coverage thereunder to the Buyer or any Insured (as defined in the Tax Insurance Policy). The Partner Counterparty shall pay (or cause to be paid) all premiums, fees, expenses and other amounts payable under the Tax Insurance Policy at least five Business Days before the same are due and shall provide written notice to the Buyer thereof.

(c)Transfer Election. With respect to the Transferred Tax Credits, the Partner Counterparty shall cause the Seller to (i) file an election to transfer the Transferred Tax Credits to the Buyer not later than the due date (including extensions, and as such date may be extended by the IRS or Treasury) for the tax return of the Seller for the taxable year for which such Transferred Tax Credits are determined and otherwise in the time and manner required by the IRS or Treasury, Applicable Laws and this Agreement, consistent with current and future guidance issued under Section 6418 of the Code (a “Transfer Election”) and (ii) provide the Buyer with the relevant portions of the Transfer Election (with redactions solely of information that is not relevant to the Transfer Election if such redactions are deemed necessary or reasonably appropriate by the Seller) and verification from the Seller’s federal income tax return preparer that the Transfer Election was properly made and the Transferred Tax Credits were properly transferred to the Buyer in the amount described in this Agreement; provided, that if the Partner Counterparty is unable to cause the Seller to provide such verification, the Partner Counterparty shall provide, or cause the Seller to provide, other evidence, reasonably satisfactory to the Buyer, that the Transfer Election was properly made and the Transferred Tax Credits were transferred to the Buyer. No later than September 13, 2024, the Partner Counterparty shall cause the Seller to deliver an executed Transfer Election Statement in substantially the form attached as Exhibit 1 (and otherwise consistent with, and including the information required by, Treasury Regulations Section 1.6418-2(b)(5) (or any updated, finalized, superseding or successor provision)) duly executed by or on behalf of the Seller.

(d)Further Assurances. Subject to the terms and conditions of this Agreement, each Party shall use commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary to consummate and make effective the Transactions; provided, however, that this clause (d) shall not prohibit or require any action (or inaction) that results in a Tax Credit Loss that is fully insured pursuant to the Tax Insurance Policy. At any time, or from time to time after the Effective Date, each Party shall, at the other Party’s reasonable request, and at the Partner Counterparty’s sole cost and expense, execute and deliver such instruments of transfer, conveyance, assignment and assumption, in addition to this Agreement, and take such other actions (including making regulatory or other filings) as any Party may reasonably request in order to further evidence and effectuate the Transactions.

(a)Partner Counterparty Indemnification. The Partner Counterparty agrees to indemnify and make whole the Buyer and its Affiliates, officers, employees and agents (collectively, the “Buyer Indemnified Parties”) against (i) any inability of the Buyer to claim, or any reduction, recapture, loss or disallowance of, all or any portion of the Transferred Tax Credits, plus additions to tax, interest and penalties imposed on the Buyer Indemnified Parties in respect thereof (including any penalty under Section 6418(g)(2)(A) of the Code) and any legal or other expenses incurred in connection with any tax audit or tax controversy with respect to the Transferred Tax Credits, (ii) any other losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Buyer Indemnified Party, incurred by or asserted against any Buyer Indemnified Party arising out of, in connection with, or as a result of any breach of a representation, warranty or covenant of the Seller, and (iii) to the extent a Change in Tax Law Termination Event occurs after the Closing Date, any losses (including recapture, loss, disallowance, reduction, additions to tax, penalties or interest) incurred by the Buyer with respect to the Transferred Tax Credits as a result of such Change in Tax Law Termination Event (collectively, a “Tax Credit Loss”), other than any Tax Credit Loss that is solely attributable to (A) a breach by the Buyer of any representation, warranty or covenant contained herein, (B) the inability of the Buyer to utilize or otherwise benefit from the Transferred Tax Credits due to the Buyer having an insufficient tax liability in the year in respect of which the Transferred Tax Credits are transferred, (C) the failure by any Buyer Indemnified Party to properly claim any Transferred Tax Credits (unless such failure was attributable to information provided by the Partner Counterparty or the Seller, or otherwise results from acts or omissions of the Seller), (D) the Buyer making any election to change its taxable year for U.S. federal income tax purposes, or (E) the gross negligence, willful misconduct or fraud undertaken by any Buyer Indemnified Party. The Buyer further acknowledges and agrees that the Buyer’s sole recourse for any indemnification pursuant to or arising from this Agreement is to the Partner Counterparty or, if applicable, to the Partner Guarantor pursuant to the Partner Guaranty, and not under any circumstance to the Seller, the Project Company or any of Seller’s members (other than the Partner Counterparty), and the Buyer waives any claim it may have against the Seller, the Project Company or any of the Seller’s members (other than the Partner Counterparty) for any indemnification pursuant to or arising from or otherwise with respect to this Agreement and the transactions contemplated hereby.

(b) Limitations on Liability. The Partner Counterparty’s aggregate indemnity obligation to the Buyer Indemnified Parties under Section 6(a) shall not exceed the sum of (i) an amount equal to 100% of the Purchase Price, (ii) additions to tax, interest and penalties imposed on, and including legal and other service costs incurred by the Buyer Indemnified Parties in connection with any resulting underpayment or the excessive transfer of Transferred Tax Credits, including any penalty under Section 6418(g)(2)(A) of the Code, (iii) all costs incurred by each applicable Buyer Indemnified Party in connection with enforcing its rights and remedies hereunder or in defending itself from any IRS or other adverse action caused hereby, and (iv) any tax gross-up amount payable pursuant to Section 6(c) (the “Indemnity Cap”), except the Indemnity Cap shall not apply to any claims of or attributable to the fraud, gross negligence or willful misconduct of the Partner Counterparty, Seller or Affiliate of

the Partner Counterparty or to any third party claims. In no event shall the Partner Counterparty have any liability under this Agreement for or in respect of any punitive, consequential, special, incidental, or exemplary damages or any nature, including damages for lost profits or revenues or the loss or use of such profits or revenues, damages to reputation, and damages for lost opportunities, in each case to the extent constituting consequential damages, regardless of whether such claim is based upon contract, warranty, tort (including negligence and strict liability) or other theory of law (but not any such damages to the extent required to be paid by a Buyer Indemnified Party pursuant to a judgment obtained by a third party against the Buyer for a claim for which the Partner Counterparty is required to provide an indemnity hereunder); provided, that any Tax Credit Loss for which the Partner Counterparty is obligated to indemnify the Buyer pursuant to Section 6(a) shall be recoverable as damages subject to the limitations described in the first sentence of this Section 6(b) and shall not constitute excludable punitive, consequential, special, incidental or exemplary damages. Each Buyer Indemnified Party (other than the Buyer) shall be an express third-party beneficiary of this Agreement for purposes of enforcing its rights pursuant to this Section 6.

( c) After-Tax Basis. For tax reporting purposes and except as otherwise provided in this Section 6(c), each Party will treat and report indemnification payments paid under any of the provisions of this Section 6 as a nontaxable reimbursement or purchase price adjustment, as the case may be; provided, however, the Parties agree that (A) (i) the Buyer’s profit from the purchase of Tax Credits under this Agreement (e.g., if the Buyer paid $0.95 for $1.00 of Tax Credits, its profit would have been $0.05) related to such indemnification payment and (ii) penalties and interest imposed by the IRS related to such indemnification payment shall be grossed up for U.S. federal, state and local income taxes, using the highest marginal U.S. federal, state and local income tax rate applicable to corporations provided for in Section 11 of the Code (or such other Applicable Law with respect to state and local taxes) as of the date of the payment and (B) if Buyer delivers to the Partner Counterparty an opinion of Mayer Brown LLP or another nationally recognized counsel reasonably agreed by the Parties that for U.S. federal, state or local income tax purposes such indemnity payment is “more likely than not” taxable income, then such indemnification payment shall be grossed up for such income taxes, using the highest marginal U.S. federal, state and local income tax rate applicable to corporations provided for in Section 11 of the Code (or such other Applicable Law with respect to state and local taxes) as of the date of the payment. In the event that any indemnification payment treated as a nontaxable reimbursement or Purchase Price adjustment is subsequently determined in a Final Determination to be includable as income of the recipient for U.S. federal, state or local income tax purposes, such indemnification payment shall also be grossed up for such taxes, using the highest marginal U.S. federal, state and local income tax rate applicable to corporations provided for in Section 11 of the Code (or such other Applicable Law with respect to state and local taxes) as of the date of the payment.

(d) Tax Contests. The Buyer shall conduct the defense of any tax controversy relating to the Transferred Tax Credits except to the extent (i) the Partner Counterparty has agreed in writing (subject to the Indemnity Cap) to indemnify the Buyer Indemnified Parties for any loss (including the loss of the Transferred Tax Credits, plus any additions to tax, interest and penalties imposed on the Buyer Indemnified Parties in respect thereof) arising as a result therefrom, (ii) the Partner Counterparty has demonstrated to the reasonable satisfaction of the applicable Buyer Indemnified Party the wherewithal of the Opal Parties, to pay such indemnity, (iii) Buyer reasonably determines that Partner Counterparty can conduct the defense of the tax controversy in its own name and not in Buyer’s name, and (iv) the applicable Buyer Indemnified Party does not affirmatively waive in writing its right to indemnification pursuant to Section 6(a) with respect to such Transferred Tax Credits. If clauses (i) through (iv) in the preceding sentence are satisfied, then the Partner Counterparty, or a representative of the Partner Counterparty, will conduct the defense of the audit, and any subsequent contest of IRS claims for which the Partner Counterparty would be obligated to indemnify the Buyer Indemnified Parties, at the Partner Counterparty’s expense; provided, that the applicable Buyer Indemnified Party shall have the right to control the defense of such tax controversy if the Buyer affirmatively waives in writing its right to indemnification pursuant to Section 6(a) with respect to the applicable Transferred Tax Credits. In such an instance, the Partner Counterparty shall keep the applicable Buyer Indemnified Party informed of any developments in such audit or contest to the extent relevant to the Transferred Tax Credits and allow the applicable Buyer Indemnified Party to

participate in such audit or contest, at the expense of such Buyer Indemnified Party, and such Buyer Indemnified Party shall cooperate with the Partner Counterparty in connection with such audit or contest. In the event that the Buyer conducts the defense of any tax controversy relating to the Transferred Tax Credits in accordance with this Section 6(d), (1) Partner Counterparty shall cooperate with the Buyer in connection with such tax controversy and (2) Buyer shall not settle, compromise, abandon or appeal such tax controversy without the Partner Counterparty’s consent (such consent not to be unreasonably withheld, conditioned or delayed); provided that in no event shall Buyer be required to pursue any judicial remedy (or otherwise pursue any remedy other than federal administrative remedies) in connection with such tax controversy. In connection with any such tax controversy or defense or contest thereof, for any matter that is not related to the Transferred Tax Credits, (y) no Buyer Indemnified Party shall have any right to participate in or control any audit or controversy that is between the IRS and the Seller (or any Affiliate of the Seller) and to which such Buyer Indemnified Party is not a party, and shall have no consent rights over any such audits, settlements, or controversies and (z) the Partner Counterparty shall have no right to participate in or control any audit or controversy that is between the IRS and the Buyer (or any Buyer Indemnified Party) and to which the Partner Counterparty or any Affiliate of the Partner Counterparty is not a party, and shall have no consent rights over any such audits, settlements, or controversies.

(e) Survival of Representations and Warranties of the Partner Counterparty. Without limiting the Partner Counterparty’s indemnification obligations set forth in this Section 6, all claims of the Buyer for breaches of any representation or warranty of the Partner Counterparty must be made within 18 months after the Payment Date, other than any of the following claims:

(i)Claims for breaches of the representations and warranties of the Partner Counterparty set forth in Section 4(a)(i) (Organization and Authority), Section 4(a)(ii) (Authorization and Execution) and Section 4(a)(iii) (No Violation) shall survive indefinitely; and

(g) Notice of Claims. If written notice of a claim for indemnification is given by the Buyer prior to the last day of the applicable survival period (as determined pursuant to Section 6(e)), then the indemnification obligations of the Partner Counterparty will survive until the final resolution of such claim.

(h) Indemnity Payment. Indemnification payments made pursuant to this Section 6 shall be due in respect of any claim (i) within twenty days after the date on which Partner Counterparty has been

notified by Buyer of such indemnification claim if such claim is not being contested in accordance with Section 6(d) or (ii) within ten Business Days of a Final Determination if such claim is being contested in accordance with Section 6(d).

(a)Amendments; Waivers. This Agreement may not be amended or modified except by an instrument in writing signed by each Party hereto. No failure or delay by any Party in exercising any right or power under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Parties hereunder are cumulative and are not exclusive of any rights or remedies that such Party would otherwise have. No waiver of any provision of this Agreement consent to any departure by any Party therefrom shall in any event be effective unless the same shall be in writing and executed by both Parties, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

Any Notice or other communication received on a day that is not a Business Day or later than 5:00 p.m. (Eastern time) on a Business Day shall be deemed to be received on the next Business Day.

(c)Entire Agreement; No Other Representations. The Transaction Documents embody the entire agreement and understanding of the Parties hereto in respect of the Transactions and supersede all prior agreements, letters of intent, representations, warranties, promises, covenants, arrangements, communications and understandings, oral or written, express or implied, between the Parties with respect to the Transactions. There are no agreements, representations, warranties, promises, covenants, arrangements or understandings between the Parties with respect to the Transactions, other than those expressly set forth or referred to herein.

This Agreement may be executed by signatures delivered by email, and a copy hereof that is executed and delivered by a Party by email (including in .pdf format) will be binding upon

Each Party acknowledges that disclosures pursuant to clause

(C) above may be subject to the Freedom of Information Act, 5 U.S.C. Section 552. If any Party becomes compelled by legal or administrative process to disclose any Confidential Information, such Party will provide the other Party with prompt Notice so that the other Party may seek a protective order or other appropriate remedy or waive compliance with the non-disclosure provisions of this Section 7(k) with respect to the information required to be disclosed. If such protective order or other remedy is not obtained, or such other Party waives compliance with the non-disclosure provisions of this Section 7(k) with respect to the information required to be disclosed, the first Party will furnish only that portion of such information that it is advised, by opinion of counsel, is legally required to be furnished and will exercise reasonable efforts, at the other Party’s expense, to obtain reliable assurance that confidential treatment will be accorded such information, including, in the case of disclosures to the IRS described in clause (D) above, to obtain reliable assurance that, to the maximum extent permitted by applicable legal requirements, such information will not be made available for public inspection pursuant to Section 6110 of the Code.

(iv)Notwithstanding anything to the contrary set forth in this Agreement, the Partner Counterparty, the Seller Parties and their Affiliates shall be permitted to share Confidential Information with their representatives and prospective purchasers, transferees or assignees of the equity interests in the Seller Parties; provided, that such Persons agree to keep such information confidential in accordance with the terms of this Section 7(k).

(v)Nothing contained in this Section 7(k) shall be construed so as to prohibit a Party from using any Confidential Information in connection with (A) any claim against the other Party,

(B) any exercise by such Party of any of its rights hereunder (including the ownership, operation and administration of the Project Company and the Facility) or (C) a disposition by the Seller or its Affiliates of all or a portion of its interest in the Project Company; provided, that such potential purchaser shall have entered into a confidentiality agreement with respect to Confidential Information on customary terms used in confidentiality agreements in connection with corporate acquisitions before any such information may be disclosed.

(vi)In addition, each Party hereby acknowledges that the U.S. federal securities laws and applicable European securities laws, among other things, prohibit certain Persons in possession of material, non-public information concerning companies or securities from buying or selling securities issued by those companies or disclosing that material, non-public information to others who buy or sell those securities while in possession of that information (or disclose that information to others who buy or sell).

For this purpose, “tax structure” is limited to facts relevant to the U.S. federal income tax treatment of the transaction and does not include information (A) relating to the identity of the Parties, their Affiliates, agents, or advisors or (B) the operation or design of the Facility.

(l) Specific Performance. In the event of a breach by a Party of the provisions of Section 2, Section 7(i) or Section 7(k), the other Party will have the right to seek specific performance and injunctive relief giving effect to its rights under this Agreement, in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies will be cumulative. The Parties hereto agree that any such breach would cause irreparable injury, that the remedies at law for any such breach, including monetary damages, are inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at law would be adequate is waived.

(m) Protection of Title; Transfers Intended as Sale; Security Interest.

(i)It is the express intent of the parties hereto that each transfer of Transferred Tax Credits by the Seller to the Buyer, as contemplated by this Agreement be, and be treated as, a sale by the Seller to the Buyer. It is, further, not the intention of the Parties that any such transfer be, or be deemed, a pledge of the Transferred Tax Credits by the Seller to the Buyer to secure a debt or other obligation of the Seller.

(ii)In the event that, notwithstanding the intent of the Parties, the Transferred Tax Credits are held by a court to continue to be property of the Seller then (A) this Agreement shall be deemed to be a security agreement within the meaning of Articles 8 and 9 of the applicable Uniform Commercial Code and (B) the transfer of Transferred Tax Credits provided for herein shall be deemed to be a grant by the Partner Counterparty, and the Partner Counterparty does hereby grant, to the Buyer a first-priority security interest in all of the Partner Counterparty’s right, title and interest in, to and under the following, whether now owned or existing or hereafter arising and wherever located: (1) the Transferred Tax Credits and the Minimum Documentation and (2) all Proceeds (as defined in the Uniform Commercial Code), voluntary or involuntary, of the foregoing. Each of the Parties shall, to the extent consistent with this Agreement, take such actions as may be reasonably necessary to ensure that, if this Agreement were deemed to create a security interest in the Transferred Tax Credits, such security interest would be deemed to be a perfected security interest of first priority under Applicable Law, including that the Partner Counterparty (on behalf of the Seller) hereby authorizes the filing of financing statements or continuation statements, and amendments to financing statements, in any jurisdictions and with any filing office as the Buyer may determine, in its sole discretion, are necessary or advisable, to the extent this Agreement were deemed to create a security interest in the Transferred Tax Credits, to perfect (or maintain) any such security interest granted to the Buyer in connection herewith. Such statements may name the Seller or the Project Company as “debtor” and the Buyer as “secured party”.

(iii)The Partner Counterparty hereby represents and warrants that as of the date hereof:

(A) the full and correct legal name of the Seller is Paragon RNG LLC, (B) its type of organization is a limited liability company, (C) its jurisdiction of organization is Delaware, (D) the Seller’s mailing address and place of business (or, if the Seller has more than one place of business, the location of the chief executive office of the Seller) is One North Lexington Avenue, Suite 1450, White Plains, NY 10601, and (E) the Seller has not, since its formation, changed its “location” (as defined in Section 9-307 of the Uniform Commercial Code), changed its name or become a “new debtor” (as defined in Section 9-102(a)(56) of the Uniform Commercial Code) with respect to a currently effective security agreement previously entered into by any other Person.

(iv)The Partner Counterparty shall notify the Buyer in writing within ten days following the occurrence of (A) any change in the Seller’s type of organization or jurisdiction of organization, (B) any change in the Seller’s “location” (within the meaning of Section 9-307 of the Unform Commercial Code), and (C) any change in the Seller’s name, and shall take all action prior to making such change reasonably necessary or advisable in the opinion of the Buyer to amend all previously filed financing statements or continuation statements described in this Section 7(m).
