This LOAN GUARANTEE AGREEMENT, dated as of October 15, 2025 (this “Agreement”), is entered into by and between the UNITED STATES DEPARTMENT OF ENERGY, an agency of the United States of America, acting in its capacity as guarantor and loan servicer of the Guaranteed Loan (“DOE”), and AEP TRANSMISSION COMPANY, LLC, a limited liability company organized and existing under the laws of the State of Delaware (the “Borrower”).

PRELIMINARY STATEMENTS

(A)DOE has been authorized to issue a guarantee for FFB to make loans for the Project Portfolio facility pursuant to Title XVII of the Energy Policy Act of 2005, Pub. L. 109 58, as amended by Section 406 of Div. A of Title IV of Pub. L. 111 5, and as further amended from time to time (“Title XVII”).

(B)The Borrower, through one or more Project Companies, anticipates undertaking projects that are identified in more detail on Schedule 5.04(b) (each, a “Project”).

(D)The Borrower and DOE entered into that certain Conditional Commitment Letter, dated January 16, 2025 (the “Conditional Commitment Letter”), pursuant to which DOE agreed to arrange for FFB to purchase the FFB Note from the Borrower and to make Advances from time to time thereunder, in each case, upon the terms and subject to the conditions of this Agreement and the other Financing Documents.

(E)Subject to the terms and conditions hereof, DOE will, in connection with arranging financing for the Borrower from FFB, issue and deliver to FFB the DOE Guarantee pursuant to which it will guarantee the Borrower’s repayment of principal and interest on the Advances as and when required pursuant to the FFB Note and any other liabilities, losses, costs or expenses incurred by FFB from time to time with respect to the FFB Note or the related FFB Note Purchase Agreement.

(F)The execution of this Agreement is a condition precedent to DOE’s issuance of the DOE Guarantee, and FFB’s receipt of the DOE Guarantee is a condition precedent to FFB’s execution of the FFB Documents.

(G)The parties hereto desire (a) to specify, among other things, the terms and conditions for (i) the delivery by DOE of the DOE Guarantee and other FFB Secretary’s Instruments required for FFB to purchase the FFB Note pursuant to the FFB Note Purchase Agreement; (ii) the delivery by DOE of Advance Request Approval Notices; and (iii) certain indemnity and reimbursement obligations of the Borrower to DOE; and (b) to provide for certain other matters related thereto.

CUI//PROPIN

02.Availability and Reductions.

(a)Maximum Guaranteed Loan Amount; Availability Period. Subject to the terms and conditions hereof and of the FFB Documents, DOE shall, during the Availability Period, deliver to FFB an Advance Request Approval Notice authorizing FFB to make Advances in accordance with Section 2.03(c)(ii) (Advance Request Approval Notice); provided, that after giving effect to any Advances and the use of proceeds thereof and subject to Section 2.06 (Determination of Advance Amounts), the aggregate amount of all Advances made to the Borrower under the FFB Note shall comply with the Debt Sizing Parameters.

(b)Loan Commitment Amount Reductions.

(i)The Borrower may, on not less than thirty (30) days’ prior written notice to DOE and upon the satisfaction of any consent requirement or other applicable provisions of this Agreement and each other Financing Document, permanently reduce the Maximum Guaranteed Loan Amount in whole or in part, but only if:

(A)the Borrower demonstrates to DOE’s satisfaction that the total funding committed and available to the Eligible Projects with respect to which an Advance has been made is sufficient to pay all remaining Project Costs for such Eligible Projects;

(B)DOE is satisfied that the proposed reduction or cancellation could not reasonably be expected to cause a Default or an Event of Default;

(C)the Borrower shall have delivered to DOE by an Acceptable Delivery Method, a certificate, in form and substance satisfactory to DOE, with respect to the matters set forth in clauses (A) and (B) above; and

(D)upon such cancellation or reduction, the Borrower shall pay all expenses and other amounts then due with respect to, or as a result of, such cancellation or reduction under this Agreement.

(ii)Once reduced or canceled, the relevant portion of the Maximum Guaranteed Loan Amount may not be increased or reinstated.

(iii)Notwithstanding the foregoing, any notice of reduction of the Maximum Guaranteed Loan Amount delivered in connection with any refinancing of any Advances with the proceeds of such refinancing or of any other incurrence of Debt or the occurrence of some other identifiable event or condition, may be, if expressly so stated to be, contingent upon the consummation of such refinancing or incurrence or occurrence of such other identifiable event or condition and may be revoked by the Borrower, in each case, subject to any limitations set forth in the FFB Documents.

(c)Initial First Advance Cut-off Date; Termination. If the Borrower has not submitted an Advance Request for the Initial First Advance by the Initial First Advance Cut-off Date, either DOE or the Borrower may terminate this Agreement upon no less than ten (10) Business Days’ prior written notice to the Borrower or DOE, as applicable. Upon such termination, the Borrower shall pay all Guaranteed Obligations (other than inchoate indemnity obligations) and other amounts then due in accordance with this Agreement and the other Financing Documents with respect to, or as a result of, such termination. Once terminated, this Agreement may not be reinstated. For the avoidance of doubt, nothing in this Agreement (and other Financing Documents, as applicable) shall require the Borrower to request or receive any Advances.

03.Mechanics for Requesting Advances.

(a)Advance Requests. Subject to the FFB Documents, from time to time during the Availability Period, the Borrower may request an Advance under the FFB Documents by delivering, by an Acceptable Delivery Method, to DOE, with a copy to the Technical Advisor, an appropriately completed request with respect to such Advance (each, an “Advance Request”) any time not less than (i) twenty-

Each Advance Request shall be in the form attached as Exhibit A (Form of Advance Request) (as such form may be amended, supplemented or modified from time to time by DOE in a manner conforming to this Agreement or otherwise with the consent of the Borrower, the “Form of Advance Request”), which form shall include (i) a confirmation that each Project covered by such Advance Request has been previously determined to be an Eligible Project by DOE, (ii) a summary of material conditions or events that have occurred since the Borrower’s last Advance Request that are required to be disclosed under the Securities Exchange Act of 1934, (iii) the amount and description of the Eligible Project Costs incurred and either expended or accrued by Borrower or the applicable Project Company for each Eligible Project included in the Advance Request (broken down on an Eligible Project-by-Eligible Project basis), as evidenced by accruals, invoices or other documentation reasonably acceptable to DOE, (iv) each such Eligible Project’s original and current budget and completion date, and (v) a certification by the Borrower that, as of the date of such Advance Request, (A) all Eligible Project Costs covered by such Advance Request are reasonably expected to be recoverable as a component of the Borrower’s or the applicable Project Company’s revenues, (B) DOE’s NEPA environmental review is complete for each Eligible Project included in the Advance Request by identifying the applicable NEPA document, and (C) after giving effect to the proposed Advance, the Borrower will be in compliance with the Debt Sizing Parameters.

(c)Advance Funding.

Promptly after receipt of an Advance Request complying with Section 2.03(a) (Advance Requests), DOE shall review such Advance Request to determine whether all certificates and documentation required to be attached thereto pursuant to this Section 2.03 (Mechanics for Requesting Advances) have been delivered to it.

(ii)Advance Request Approval Notice. With respect to any Advance under the FFB Documents, if DOE determines that: (x) the Advance Request has been satisfactorily completed pursuant to this Section 2.03 (Mechanics for Requesting Advances); and (y) all conditions precedent set forth in Section 5.03 (Advance Approval Conditions Precedent) in respect of the requested Advance have been satisfied (or waived in writing by DOE), then, subject to Section 2.03(d) (Drawstop Notices) below, DOE shall promptly provide notice thereof to the Borrower and issue to FFB an Advance Request Approval Notice no later than (A) five (5) Business Days prior to the Requested Advance Date if such Advance Request is equal to or greater than Five Hundred Million Dollars ($500,000,000) and (B) three (3) Business Days prior to the Requested Advance Date if such Advance Request is less than Five Hundred Million Dollars ($500,000,000).

(iii)Funding. For any requested Advance for which an Advance Request Approval Notice has been issued pursuant to this Section 2.03(c) (Advance Funding) and for which no Drawstop Notice has been issued pursuant to Section 2.03(d) (Drawstop Notices), FFB shall fund such Advance on the Requested Advance Date in accordance with the FFB Note Purchase Agreement and the relevant FFB Note. Such funds shall be applied as specified in the FFB Documents and in accordance with Section 2.03(f) (Disbursement of Proceeds); provided, that if any Drawstop Notice has been issued and is in effect on the Requested Advance Date with respect to any funds received by the Borrower, such funds (together with any additional amounts due thereon or arising therefrom) shall be returned by the Borrower to FFB pursuant to Section 2.03(d) (Drawstop Notices).

(d)Drawstop Notices.

(i)Issuance. Following the issuance of any Advance Request Approval Notice by DOE pursuant to Section 2.03(c)(ii) (Advance Request Approval Notice) above and on or prior to the Requested Advance Date, DOE or FFB may, from time to time, issue a notice substantially in the form attached hereto as Exhibit B (Form of Drawstop Notice) (a “Drawstop Notice”) to the Borrower and to DOE or FFB, as the case may be, if and only if DOE or FFB, as the case may be, determines in its sole discretion that:

CUI//PROPIN

(A)any condition set forth in Section 5.03 (Advance Approval Conditions Precedent) and Section 5.05 (Conditions Precedent to FFB Advance), as applicable, with respect to such Advance is not satisfied; or

(B)the conditions precedent to such Advance contained in the relevant FFB Note and the FFB Note Purchase Agreement are not satisfied.

(ii)Consequences. If a Drawstop Notice is issued, FFB shall not be obligated to make the requested Advance set forth on such Drawstop Notice; provided, that if FFB makes any such Advance to the Borrower following the issuance of a Drawstop Notice, the Borrower shall return such Advance to FFB within one (1) Business Day following receipt thereof; provided, further, that any amount required to be returned by the Borrower pursuant to this clause (ii) shall accrue interest from the date such Advance is made until and including the date such Advance is returned but shall not be subject to the Late Charge Rate or payment of a make-whole amount in accordance with the relevant FFB Note. Following the return of such Advance, FFB shall deliver an invoice to the Borrower setting forth the interest due and payable with respect to such returned amount. The Borrower shall pay promptly, but in no event later than five (5) Business Days following delivery of such invoice, such interest as directed by FFB, and the Borrower shall pay all reasonable costs and expenses of outside counsel incurred by DOE, FFB or the Designated Agent as a result of such Advance withdrawal.

(e)No Liability.

(i)The Borrower acknowledges and agrees that DOE shall only be required to use its reasonable efforts to provide FFB with the necessary Advance Request Approval Notices within the time frames specified in Section 2.03(c)(ii) (Advance Request Approval Notice) but DOE shall in any event ensure that FFB receives all such Advance Requests and Advance Request Approval Notices as soon as reasonably practicable following receipt from the Borrower of the applicable Advance Requests and certificates and other documentation specified above (subject to the Borrower satisfying all conditions precedent specified in this Agreement, Section 5.03 (Advance Approval Conditions Precedent) and Section 5.05 (Conditions Precedent to FFB Advance), as applicable, and, prior to the Effective Date, Section 5.01 (Conditions Precedent to the Effective Date) and Section 5.02 (Conditions Precedent to FFB Purchase of the FFB Note), respectively).

(ii)Neither DOE nor FFB shall have any liability for any action taken (including the delivery of a Drawstop Notice) or omitted to be taken (including the refusal to fund any Advance or Advances following the issuance of a Drawstop Notice) or for any loss or injury resulting from its actions or inaction or its performance or lack of performance of any of its other obligations hereunder unless and solely to the extent such liability arises from the bad faith, gross negligence or willful misconduct of DOE or FFB as determined by a court of competent jurisdiction in a final, non-appealable judgment. In no event shall DOE, FFB or any subsequent holder of the FFB Note be liable, and each such Person shall be exempt from liability in accordance with Section 11.08 (Limitation on Liability), in each case: (A) for acting in accordance with, or relying upon, any entitlement order, instruction, notice, demand, certificate or document from the Borrower or any authorized Person acting on behalf of the Borrower; (B) for any indirect, consequential, punitive or special damages, regardless of the form of action and whether such damages were foreseeable or contemplated; or (C) in the case of FFB or any subsequent holder of the FFB Note, for acting in accordance with, or relying upon, any Drawstop Notice issued by DOE.

(iii)Notwithstanding anything contained in this Agreement to the contrary, neither DOE nor FFB shall incur any liability to the Borrower, any Affiliate thereof or to any other Guaranteed Party for not performing any act or fulfilling any duty, obligation or responsibility hereunder or under any other Financing Document by reason of any Guaranteed Party Force Majeure Event; it being understood that DOE or FFB, as the case may be, shall resume performance hereunder as soon as reasonably practicable after the effects of such Guaranteed Party Force Majeure Event cease to prevent or otherwise hinder DOE or FFB, as applicable, from performing hereunder or thereunder.

(f)Disbursement of Proceeds.

(i)The Borrower shall apply the proceeds of any Advance solely towards payment or reimbursement of Eligible Project Costs for each such Eligible Project with respect to which such Advance was requested that have been previously incurred and either expended or accrued by the Borrower or a Project Company, as evidenced by accruals, invoices or other documentation delivered in connection with the applicable Advance Request under Section 2.03(a) (Advance Requests), such evidence to be in form and substance reasonably acceptable to DOE and otherwise subject to the audit rights of DOE and FFB.

(ii)In no event shall the proceeds of any Advance be:

(A)used for any Project other than each Eligible Project with respect to which such Advance was requested (and in the amounts so requested for each such Eligible Project);

Notwithstanding the foregoing, an Event of Default (the “Initial Default”) may not be cured pursuant to clauses (1)(A), (2)(A) or (2)(B) of the immediately preceding sentence (x) if any of DOE, the Designated Agent or FFB has declared all or any portion of the indebtedness and obligations owed by the Borrower under this Agreement or any other Financing Document to be immediately due and payable; or (y) if any Guaranteed Party has begun exercising any rights or remedies under any Financing Documents during the continuance of such Initial Default.

(c)Unless otherwise expressly provided, no remedy herein conferred upon or reserved is intended to be exclusive of any other available remedy, but each remedy shall be cumulative and shall be in addition to other remedies given under the Financing Documents or existing at law or in equity. No delay or failure to exercise any right or power accruing under any Financing Document upon the occurrence and during the continuance of any Event of Default or otherwise shall impair or delay any such right or power or shall be construed to be a waiver thereof, but any such right and power may be exercised from time to time and as often as may be deemed expedient.

(d)In order to entitle the Guaranteed Parties to exercise any remedy reserved to the Guaranteed Parties in this Agreement or any other Financing Document, it shall not be necessary to give any notice, other than such notice as may be required in this Agreement, any other Financing Document or under Applicable Law.

(e)If any proceeding has been commenced to enforce any right or remedy under this Agreement, and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to DOE or FFB, then and in every such case, subject, in each case, to any determination in such proceeding: (i) the parties hereto shall be restored to their respective former positions hereunder; and (ii) thereafter, all rights and remedies of DOE or FFB, as the case may be, shall continue as though no such proceeding had been instituted.

(f)DOE shall have the right, to be exercised (or not) in its complete discretion, to waive any covenant, Default or Event of Default by a writing setting forth the terms, conditions and extent of such waiver signed by ▇▇▇ and delivered to the other parties hereto. Any such waiver may be effected only in writing duly executed by ▇▇▇, and no other course of conduct shall constitute a waiver of any provision hereof. Unless such writing expressly provides to the contrary, any waiver so granted shall extend only to the specific event or occurrence so waived and not to any other similar event or occurrence that occurs subsequent to the date of such waiver.

03.Accelerated Advances. Upon the delivery of a notice of acceleration, the accelerated amount due and payable under the FFB Note shall be the Prepayment Price under the FFB Note.

(d)Any amendment to or waiver of this Agreement or any other Financing Document or any provision hereof or thereof that constitutes a “modification” (as defined in Section 502(9) of FCRA) that increases the amount of the Credit Subsidy Cost (as calculated in accordance with FCRA and OMB Circulars A-11 and A-129) shall be subject to the availability to DOE of funds appropriated by the U.S. Congress or, to the extent permitted by Applicable Law, payment by the Borrower, to meet any such increase in the Credit Subsidy Cost.
