Within the limits of each Lender’s Commitment from time to time and as hereinabove and hereinafter provided, the Borrower may request Borrowings hereunder, and repay or prepay Advances pursuant to Section 2.11. Amounts repaid or prepaid in respect of Advances may not be reborrowed.

(b)In the event any increase in the Facility and the Commitments thereunder is undertaken pursuant to Section 2.18, the Borrower shall be required to make a Borrowing in an amount equal to such increased Commitments on the date which is not more than five (5) Business Days following the effectiveness of such increase pursuant to the terms of Section 2.02.

SECTION 2.02. Making the Advances.

(a)Each Borrowing shall consist of Advances of the same Type made on the same day by the Lenders ratably according to their respective Commitment Percentages. The Borrower shall give notice to the Administrative Agent, (i) not later than 11:00 A.M. three (3) Business Days prior to the applicable Borrowing Date, of a Borrowing consisting of Eurodollar Rate Advances, or (ii) not later than 9:30 A.M. on the applicable Borrowing Date, in the case of a Borrowing consisting of Base Rate Advances, and the Administrative Agent shall give to each Lender prompt written notice of such Borrowing. Each such notice of a Borrowing under this Section 2.02 (a “Notice of Borrowing”) shall be by telephone, confirmed immediately in writing, or fax in substantially the form of Exhibit A hereto, specifying therein the requested (i) Borrowing Date for such Borrowing, (ii) Type of Advances comprising such Borrowing, (iii) aggregate amount of such Borrowing, and (iv) in the case of a Borrowing consisting of Eurodollar Rate Advances, the initial Interest Period for each such Advance. Each Lender shall, before 12:00 Noon on the applicable Borrowing Date, make available for the account of its Applicable Lending Office to the Administrative Agent at the Agent’s Account, in same day funds, such Lender’s ratable portion of the Borrowing to be made on such Borrowing Date. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Section 3.02, the Administrative Agent will promptly make such funds available to the Borrower in such manner as the Borrower shall have specified in the applicable Notice of Borrowing and as shall be reasonably acceptable to the Administrative Agent.

(b)Anything in subsection (a) above to the contrary notwithstanding, (i) the Borrower may not select Eurodollar Rate Advances if the obligation of the Lenders to make Eurodollar Rate Advances shall then be suspended pursuant to Section 2.09.

23

(c)Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing that the related Notice of Borrowing specifies is to comprise Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Section 3.02, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

(d)Unless the Administrative Agent shall have received notice in writing from a Lender prior to any Borrowing Date or, in the case of a Base Rate Advance, prior to the time of Borrowing, that such Lender will not make available to the Administrative Agent such Lender’s Advance as part of the Borrowing to be made on such Borrowing Date, the Administrative Agent may, but shall not be required to, assume that such Lender has made such portion available to the Administrative Agent on such Borrowing Date in accordance with subsection (a) of this Section 2.02, and the Administrative Agent may (but it shall not be required to), in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such Advance available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement.

(e)The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

24

Lender declines to consent to extending the Termination Date or (B) such Lender consents to extending the Termination Date. Any Lender not responding within the above time period shall be deemed not to have consented to extending the Termination Date. The Administrative Agent shall, after receiving the notifications from all of the Lenders or the expiration of such period, whichever is earlier, notify the Borrower and the Lenders of the results thereof. The Borrower may request no more than one extension pursuant to this Section.

(b)If any Lender declines, or is deemed to have declined, to consent to such request for extension (each a “Declining Lender”), the Borrower shall have the right to replace such Declining Lender in accordance with Section 2.17(b). Any Lender replacing a Declining Lender shall be deemed to have consented to such request for extension (regardless of when such replacement is effective) and shall not be deemed to be a Declining Lender.

(c)If the Required Lenders have consented to the extension of the Termination Date, the Termination Date shall be extended (solely with respect each Lender that consented to the extension) to the date that is one year after the then-effective Termination Date, effective as of the date to be determined by the Administrative Agent and the Borrower (the “Extension Effective Date”). On or prior to the Extension Effective Date, the Borrower shall deliver to the Administrative Agent, in form and substance satisfactory to the Administrative Agent, (i) the resolutions of the Borrower authorizing such extension, certified as being in effect as of the Extension Effective Date and the related incumbency certificate of the Borrower, (ii) a favorable opinion of counsel for the Borrower (which may be an attorney of American Electric Power Service Corporation), as to such matters as any Lender through the Administrative Agent may reasonably request and (iii) a certificate of the Borrower stating that on and as of such Extension Effective Date, and after giving effect to the extension to be effective on such date, all conditions precedent to an Extension of Credit are satisfied. On each Extension Effective Date, the Declining Lender shall have received payment in full of the principal amount of all Advances outstanding owing to such Declining Lender and all interest thereon and all fees and other amounts (including, without limitation, any amounts payable pursuant to Section 8.04(c)) payable to such Declining Lender accrued through such Extension Effective Date.

(d)Any Lender may request that any Advances made by it be evidenced by one or more promissory notes. In such event, the Borrower shall prepare, execute and deliver to such Lender one or more promissory notes payable to such Lender (or, if requested by such Lender, to such Lender and its assignees) and in a form approved by the Administrative Agent.

During such periods as such Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for such Advance to the sum of (x) the Eurodollar Rate for such Interest Period for such Advance plus (y) the Applicable Margin for Eurodollar Rate Advances, payable in arrears on the last day of such Interest Period and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest Period every three months from the first day of such Interest Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full.

26

(c)Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to each Lender, so long as such Lender shall be required under regulations of the Board of Governors of the Federal Reserve System to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Lender, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest shall be determined by such Lender and notified to the Borrower through the Administrative Agent.

SECTION 2.09. Interest Rate Determination.

(a)The Administrative Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Administrative Agent for purposes of Section 2.08(a) or (b), and, if applicable, the rate for the purpose of determining the applicable interest rate under Section 2.08(c).

(b)If, with respect to any Eurodollar Rate Advances, (i) the Required Lenders notify the Administrative Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, or (ii) the Administrative Agent determines that adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Eurodollar Rate, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon (A) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (B) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

(c)If the Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, the Administrative Agent will forthwith so notify the Borrower and the Lenders and such Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Advances.

(d)On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $10,000,000, such Advances shall automatically Convert into Base Rate Advances.

(e)Upon the occurrence and during the continuance of any Event of Default, (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended.

27

SECTION 2.10. Optional Conversion of Advances.

The Borrower may on any Business Day, upon notice given to the Administrative Agent not later than 12:00 noon on the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.09 and 2.13, Convert all or any part of Advances of one Type comprising the same Borrowing into Advances of the other Type or of the same Type but having a new Interest Period; provided, however, that any Conversion of Eurodollar Rate Advances into Base Rate Advances shall be made only on the last day of an Interest Period for such Eurodollar Rate Advances, any Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in an amount not less than the minimum amount specified in Section 2.02(b) and no Conversion of any Advances shall result in more separate Borrowings than permitted under Section 2.02(b). Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Advances to be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each such Advance. Each notice of Conversion shall be irrevocable and binding on the Borrower.

SECTION 2.11. Optional Prepayments of Advances.

The Borrower may, upon at least two Business Days’ notice, in the case of Eurodollar Rate Advances, and upon notice not later than 11:00 A.M. (New York City time) on the date of prepayment, in the case of Base Rate Advances, to the Administrative Agent stating the proposed date and aggregate principal amount of the prepayment, and, if such notice is given, the Borrower shall prepay the outstanding principal amount of the Advances comprising part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that (x) each partial prepayment shall be in a minimum amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof, and (y) in the event of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(c).

SECTION 2.12. Increased Costs.

(a)Increased Costs Generally. If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the Eurodollar Rate Reserve Percentage, in the case of Eurodollar Rate Advances);

(ii)subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

28

(iii)impose on any Lender or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Advances made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Advance or of maintaining its obligation to make any such Advance, or to reduce the amount of any sum received or receivable by such Lender or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or other Recipient, the Borrower will pay to such Lender or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

(b)Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any Applicable Lending Office of such Lender or such Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Advances made by such Lender, such Lender, to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c)Certificates for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company, as the case may be, as specified in subsection (a) or (b) of this Section and delivered to the Borrower, shall be conclusive absent manifest error. The Borrower shall pay such Lender, as the case may be, the amount shown as due on any such certificate within ten days after receipt thereof.

(d)Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased costs incurred or reductions suffered more than six months prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and of such Lender’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 six-month period referred to above shall be extended to include the period of retroactive effect thereof).

SECTION 2.13. Illegality.

If due to any Change in Law it shall become unlawful or impossible for any Credit Party (or its Eurodollar Lending Office) to make, maintain or fund its Eurodollar Rate Advances, and such Credit Party shall so notify the Administrative Agent, the Administrative Agent shall forthwith give notice thereof to the other Credit Parties and the Borrower, whereupon, until such Credit Party notifies the Borrower and the Administrative Agent that the circumstances giving

29

rise to such suspension no longer exist, the obligation of such Credit Party to make Eurodollar Rate Advances, or to Convert outstanding Advances into Eurodollar Rate Advances, shall be suspended. Before giving any notice to the Administrative Agent pursuant to this Section 2.13, such Credit Party shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions applicable to such Credit Party) to designate a different Eurodollar Lending Office if such designation would avoid the need for giving such notice and would not, in the judgment of such Credit Party, be otherwise disadvantageous to such Credit Party. If such notice is given, each Eurodollar Rate Advance of such Credit Party then outstanding shall be converted to a Base Rate Advance either (i) on the last day of the then current Interest Period applicable to such Eurodollar Rate Advance if such Credit Party may lawfully continue to maintain and fund such Advance to such day or (ii) immediately if such Credit Party shall determine that it may not lawfully continue to maintain and fund such Advance to such day.

SECTION 2.14. Payments and Computations.

(a)The Borrower shall make each payment to be made by it hereunder not later than 1:00 P.M. on the day when due in Dollars to the Administrative Agent at the Agent’s Account in same day funds without condition or deduction for any counterclaim, defense, recoupment or setoff. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or fees ratably (other than amounts payable pursuant to Section 2.08(c), 2.12, 2.15, 8.04(c) or 8.16) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Assumption and recording of the information contained therein in the Register pursuant to Section 8.07(c), from and after the effective date specified in such Assignment and Assumption, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b)The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder, after any applicable grace period, to charge from time to time against any or all of the Borrower’s accounts with such Lender any amount so due.

(c)All computations of interest based on the rate referred to in clause (i) of the definition of the “Base Rate” contained in Section 1.01 shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate and of fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d)Whenever any payment hereunder 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 payment of interest or

30

fees, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month or on a date after the Termination Date, such payment shall be made on the next preceding Business Day.

(e)Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to a Lender hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date, and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate.

SECTION 2.15. Taxes.

(a)Defined Terms. For purposes of this Section 2.15, the term “Applicable Law” includes FATCA.

(b)Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by Applicable Law. If any Applicable Law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with Applicable Law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c)Payment of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with Applicable Law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d)Indemnification by the Borrower. The Borrower shall indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

31

(e)Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 8.07(d) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this subsection (e).

(f)Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 2.15, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(g)Status of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.15(g)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii)Without limiting the generality of the foregoing,

(A)any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

32

(B)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(i)in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed copies of IRS Form W-8BEN or W‑8BEN‑E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN or W‑8BEN‑E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(ii)executed copies of IRS Form W-8ECI;

(iii)in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Internal Revenue Code, (x) a certificate substantially in the form of Exhibit D-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Internal Revenue Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Internal Revenue Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or W‑8BEN‑E;

(iv)to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, W‑8BEN‑E, a U.S. Tax Compliance Certificate substantially in the form of Exhibit D-2 or Exhibit D-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that, if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit D-4 on behalf of each such direct and indirect partner;

(C)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D)if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in

33

Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by Applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

(h)Treatment of Certain Refunds. 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 2.15 (including by the payment of additional amounts pursuant to this Section 2.15), 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 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 subsection (h) (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 subsection (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this subsection (h) 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 subsection 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.

(i)FATCA Withholding. For purposes of determining withholding Taxes imposed under FATCA, from and after the Closing Date, the Borrower and the Administrative Agent shall treat (and the Lenders hereby authorize the Administrative Agent to treat) the obligations of the Borrower set forth in this Agreement as not qualifying as a “grandfathered obligation” within the meaning of Treasury Regulation Sections 1.1471-2(b)(2)(i) and 1.1471-2T(b)(2)(i).

(j)Survival. Each party’s obligations under this Section 2.15 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

34

SECTION 2.16. Sharing of Payments, Etc.

(a)If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances owing to it (other than pursuant to Section 2.08(c), 2.12, 2.15, 8.04(c) or 8.16 or in respect of Eurodollar Rate Advances converted into Base Rate Advances pursuant to Section 2.13) by the Borrower in excess of its ratable share of payments on account of the Advances to the Borrower obtained by all the Lenders, such Lender shall forthwith purchase from the other Lenders such participations in such Advances owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that 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 such 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 (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.16 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

(b)If any Lender shall fail to make any payment required to be made by it pursuant to Sections 2.02(d) or 7.05, then the Administrative Agent may, in its discretion and notwithstanding any contrary provision hereof, (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender for the benefit of the Administrative Agent to satisfy such Lender’s obligations to it or them under such Section until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under any such Section, in the case of each of clauses (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

SECTION 2.17. Mitigation Obligations; Replacement of Lenders.

(a)Designation of a Different Lending Office. If any Lender delivers a notice pursuant to Section 2.13, requests compensation under Section 2.12, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different Applicable Lending Office 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 pursuant to Section 2.12 or 2.15, as the case may be, 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. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)Replacement of Lenders. If any Lender delivers a notice pursuant to Section 2.13, requests compensation under Section 2.12, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the

35

account of any Lender pursuant to Section 2.15 and, in each case, such Lender has declined or is unable to designate a different Applicable Lending Office in accordance with Section 2.17(a), or if any Lender is a Declining Lender, a Defaulting Lender or a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon 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 8.07), all of its interests, rights (other than its existing rights to payments pursuant to Section 2.12 or 2.15) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if such Lender accepts such assignment); provided that:

(i)the Borrower shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 8.07(b)(iv);

(ii)such Lender shall have received payment of an amount equal to the outstanding principal of its Advances, together with all applicable accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 8.04(c)) from the assignee (to the extent of such outstanding principal amounts and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii)in the case of any such assignment resulting from a claim for compensation under Section 2.12 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments thereafter;

(iv)no Default shall have occurred and be continuing;

(v)such assignment does not conflict with Applicable Law; and

(vi)in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 2.18. Option to Increase Facility.

(c)Upon the written request of the Borrower delivered to the Administrative Agent on or before the date that falls 10 months after the Closing Date (the “Availability Date”), which request from the Borrower can be made no more than twice during the period from and including the Closing Date through the Availability Date (each such request in the form of Exhibit E hereto, a “Request for Facility Increase”), the Administrative Agent shall request that Lenders increase their Commitment under the Facility; provided, that (v) in connection with such request, the Borrower may, at its sole expense and effort, seek to obtain new Commitments from any Person that is not a Lender at such time if such Person is an Eligible Assignee, (w) no Lender

36

shall be obligated to increase its Commitment without its prior written consent, (x) any such requested increase must be in a minimum additional aggregate amount of $50,000,000, and integral multiples of $10,000,000 in excess thereof, (y) after giving effect to the increase in Commitments, the sum of (i) the aggregate principal amount of all Advances (disregarding any repayments or prepayments of Advances occurring on or prior to the date of such increase) plus (ii) the Commitments in effect at such time shall not exceed $1,000,000,000 and (z) at the time of and after giving effect to the increase in Commitments and the concurrent funding of Advances, if any, the representations and warranties of the Borrower set forth herein are true and correct and no Default has occurred and is continuing and (z) such increased Commitment shall, for the avoidance of doubt, be on the same terms and conditions as the existing Commitments.

Since December 31, 2019, there has been no Material Adverse Change. As of the Closing Date, the information included in the Beneficial Ownership Certification is true and correct in all respects.

The Borrower and each of its ERISA Affiliates have complied in all material respects with ERISA and the Internal Revenue Code. The Borrower and each of its Subsidiaries have complied in all material respects with foreign law applicable to its Foreign Plans, if any. As used herein, the term “Plan” means an “employee pension benefit plan” (as defined in Section 3 of ERISA) which is and has been established or maintained, or to which contributions are or have been made or should be made according to the terms of the plan, by the Borrower or any of its ERISA Affiliates.

(k)The Borrower is not engaged in the business of extending credit for the purpose of buying or carrying Margin Stock, and no proceeds of any Advance will be used to buy or carry any Margin Stock or to extend credit to others for the purpose of buying or carrying any Margin Stock.

(l)Neither the Borrower nor any Significant Subsidiary is an “investment company,” or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company”, as such terms are defined in the Investment Company Act of 1940, as amended. Neither the making of any Extension of Credit, the application of the proceeds or repayment thereof by the Borrower nor the consummation of the other transactions contemplated hereby will violate any provision of such Act or any rule, regulation or order of the SEC thereunder.

(m)All Significant Subsidiaries as of the date hereof are listed on Schedule 4.01(m) hereto.

(n)The Borrower has implemented and maintains in effect policies and procedures designed to ensure compliance by the Borrower, its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions, and the Borrower, its Subsidiaries and their respective directors and officers and, to the knowledge of the Borrower, its employees and agents, are in compliance with Anti-Corruption Laws and applicable Sanctions in all material respects.

THE ADMINISTRATIVE AGENT

SECTION 7.01. Authorization and Action.

Each Lender hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers and discretion as are reasonably incidental thereto. As to any matters expressly provided for in this Agreement as being subject to the discretion of the Administrative Agent, such matters shall be subject to the sole discretion of the Administrative Agent, its directors, officers, agents and employees. As to any matters not expressly provided for by this Agreement (including, without limitation, enforcement or collection of the outstanding Borrowings), the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders, and such instructions shall be binding upon all Lenders; provided, however, that the Administrative Agent shall not be required to take any action that exposes the Administrative Agent to personal liability or that is contrary to this Agreement or Applicable Law. The Administrative Agent agrees to give to each Lender prompt notice of each notice given to it by the Borrower pursuant to the terms of this Agreement.

SECTION 7.02. Agent’s Reliance, Etc.

Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for its or their own gross negligence or willful misconduct as determined in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the generality of the foregoing, the Administrative Agent: (i) may treat each Lender recorded in the Register as the owner of the Commitment recorded for such Lender in the Register until the Administrative Agent receives and accepts an Assignment and Assumption entered into by such Lender, as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07 and except as provided otherwise in Section 8.16; (ii) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement; (iv) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of any Lender or to inspect the property (including the books and records) of any Lender; (v) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, this Agreement or any other instrument or document

49

furnished pursuant thereto; (vi) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by fax) believed by it to be genuine and signed or sent by the proper party or parties; and (vii) shall not have any fiduciary duty to any other Lender.

SECTION 7.03. Administrative Agent and its Affiliates.

With respect to its Commitments and the Advances made by it, the Person serving as Administrative Agent shall have the same rights and powers in its capacity as a Lender under this Agreement 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, 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, act as trustee under indentures of, own securities of, act as the financial advisor for, accept investment banking engagements from and generally engage in any kind of business with, the Borrower, any Lender and any of their respective Subsidiaries or Affiliates thereof as if such Person were not the Administrative Agent and without any duty to account therefor to the Lenders.

SECTION 7.04. Lender Credit Decision.

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on the financial statements referred to in Section 4.01 and such other 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 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.

SECTION 7.05. Indemnification.

Each Lender severally agrees to indemnify the Administrative Agent and each of its Related Parties (to the extent not promptly reimbursed by the Borrower and without limiting its obligation to do so) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent or such Related Party in any way relating to or arising out of this Agreement or any action taken or omitted by such Person under this Agreement; provided, however, that no Lender shall be liable, as to the Administrative Agent or any of its Related Parties, for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of such Person as determined in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent and each of its Related Parties promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and reasonable expenses of counsel) payable by the Borrower under Section 8.04, to the extent that the Administrative Agent or such Related Party is not promptly reimbursed for such costs and expenses by the Borrower after request therefor and without limiting the Borrower’s obligation to do so. For purposes of this Section 7.05, the Lenders’ respective ratable shares of any amount

50

shall be determined, at any time, according to the sum of (i) the aggregate principal amount of the Advances outstanding at such time and owing to the respective Lenders and (ii) the aggregate unused portions of their respective Commitments at such time. In the event that any Lender shall have failed to make any Advance as required hereunder, such Lender’s Commitment shall be considered to be unused for purposes of this Section 7.05 to the extent of the amount of such Advance. The failure of any Lender to reimburse the Administrative Agent or any of its Related Parties promptly upon demand for its ratable share of any amount required to be paid by the Lender to the Administrative Agent or such Related Party as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse the Administrative Agent or such Related Party for its ratable share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse the Administrative Agent or such Related Party for such other Lender’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this Section 7.05 shall survive the payment in full of principal, interest and all other amounts payable hereunder.

SECTION 7.06. Successor Agent.

The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Agent to the Administrative Agent that has resigned. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation, then such retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a Lender or an Affiliate of a Lender that is a commercial bank organized under the laws of the United States or of any State thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Agent, such successor Administrative Agent shall succeed to and become vested with all the rights, powers, discretion, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to subsection (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.12, 2.15 and 8.04with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed in writing by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this subsection shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with subsection (d) of this Section.

The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement.

For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 7.05 with respect to any payments made by such Lender to its Participant(s).

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in clauses (ii), (iii) or (iv) of the first sentence of Section 8.01that affects such Participant The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.12, 2.15, 8.04(b) and 8.04(c) (subject to the requirements and limitations therein, including the requirements under Section 2.15(g) (it being understood that the documentation required under Section 2.15(g) shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 2.17(b) as if it were an assignee under subsection (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 2.12or 2.15, 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.

To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.05 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.15as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the

59

principal amounts (and stated interest) of each Participant’s interest in the Commitments, Advances or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Advances or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitments, Advances or other obligations are in registered form under Section 5f.103-1(c) of the United States Treasury Regulations.

FORM OF OPINION OF COUNSEL FOR THE BORROWER

To each of the Lenders party to the

Credit Agreement referred to below

and to PNC Bank, National Association, as Administrative Agent thereunder

March 23, 2020

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 3.01(a)(iii) of the Credit Agreement, dated as of March 23, 2020 (the “Credit Agreement”) among American Electric Power Company, Inc. (the “Borrower”), the Lenders party thereto and PNC Bank, National Association, as Administrative Agent. Terms defined in the Credit Agreement are used herein as therein defined.

I am an Associate General Counsel for American Electric Power Service Corporation, an affiliate of the Borrower, and have acted as counsel to the Borrower in connection with the preparation, execution and delivery of the Credit Agreement. I am generally familiar with the Borrower’s corporate history, properties, operations and charter (including amendments, restatements and supplements thereto).

In connection with this opinion, I, or attorneys over whom I exercise supervision, have examined:

(1) The Credit Agreement and the promissory notes issued by the Borrower on the date hereof pursuant to Section 2.07(d) of the Credit Agreement (collectively, the “Loan Documents”).

(2) The documents furnished by the Borrower pursuant to Article III of the Credit Agreement.

(3) The certificate of incorporation of the Borrower and all amendments thereto.

(4) The by-laws of the Borrower and all amendments thereto.

(5) A certificate of the Secretary of State of New York, dated March [ ], 2020, attesting to the continued existence and good standing of the Borrower in that State.

In addition, I, or attorneys over whom I exercise supervision, have examined the originals, or copies certified to my satisfaction, of such other corporate records of the Borrower, certificates

D-3

of public officials and of officers of the Borrower, and agreements, instruments and other documents, as I have deemed necessary as a basis for the opinions expressed below.

In my examination, I, or attorneys over whom I exercise supervision, have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. In making our examination of documents and instruments executed or to be executed by persons other than the Borrower, I, or attorneys over whom I exercise supervision, have assumed that each such other person had the requisite power and authority to enter into and perform fully its obligations thereunder, the due authorization by each such other person for the execution, delivery and performance thereof and the due execution and delivery thereof by or on behalf of such person of each such document and instrument. In the case of any such person that is not a natural person, I, or attorneys over whom I exercise supervision, have also assumed, insofar as it is relevant to the opinions set forth below, that each such other person is duly organized, validly existing and in good standing under the laws of the jurisdiction in which it was created and is duly qualified and in good standing in each other jurisdiction where the failure to be so qualified could reasonably be expected to have a material effect upon its ability to execute, deliver and/or perform its obligations under any such document or instrument. I, or attorneys over whom I exercise supervision, have further assumed that each document, instrument, agreement, record and certificate reviewed by us for purposes of rendering the opinions expressed below has not been amended by any oral agreement, conduct or course of dealing between the parties thereto.

As to questions of fact material to the opinions expressed herein, I have relied upon certificates and representations of officers of the Borrower (including but not limited to those contained in the Credit Agreement and certificates delivered upon the execution and delivery of the Credit Agreement) and of appropriate public officials, without independent verification of such matters except as otherwise described herein.

Whenever my opinions herein with respect to the existence or absence of facts are stated to be to my knowledge or awareness, it is intended to signify that no information has come to my attention or the attention of other counsel working under my direction in connection with the preparation of this opinion letter that would give me or them actual knowledge of the existence or absence of such facts. However, except to the extent expressly set forth herein, neither I nor they have undertaken any independent investigation to determine the existence or absence of such facts, and no inference as to my or their knowledge of the existence or absence of such facts should be assumed.

I am a member of the Bar of the States of New York and Ohio and do not purport to be expert on the laws of any jurisdiction other than the laws of the States of New York and Ohio and the Federal laws of the United States. My opinions expressed below are limited to the law of the States of New York and Ohio and the Federal law of the United States.

Based upon the foregoing and upon such investigation as I have deemed necessary, and subject to the limitations, qualifications and assumptions set forth herein, I am of the following opinion:

D-4

1. The Borrower (a) is a corporation duly organized, validly existing and in good standing under the laws of the State of New York; (b) has the corporate power and authority, and the legal right, to own and operate its property, to lease the property which it operates as lessee and to conduct the business in which it is currently engaged and in which it proposes to be engaged after the date hereof; (c) is duly qualified as a foreign corporation and is in good standing under the laws of each jurisdiction where its ownership, lease or operation of property or the conduct of its business requires such qualification, except any such jurisdiction where the failure to so qualify could not, in the aggregate, reasonably be expected to result in a Material Adverse Change; (d) owns or possesses all material licenses and permits necessary for the operation by it of its business as currently conducted; and (e) is in compliance with all Requirements of Law, except as disclosed in the Disclosure Documents referenced in Section 4.01(e) of the Credit Agreement or to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect. The term “Requirements of Law” means the laws of the State of New York and the laws, rules and regulations of the United States of America (including, without limitation, ERISA and Environmental Laws) and orders of any governmental authority applicable to the Borrower.

2. The Borrower has the corporate power and authority, and the legal right, to execute and deliver each Loan Document and to perform its obligations under each Loan Document, and to borrow under the Credit Agreement. The Borrower has taken all necessary corporate action to authorize the execution, delivery and performance of each Loan Document and the incurrence of Advances on the terms and conditions of the Credit Agreement, and each Loan Document has been duly executed and delivered by the Borrower. Each Loan Document constitutes the valid and legally binding obligation of the Borrower enforceable against the Borrower in accordance with its terms.

3. The execution, delivery and performance of each Loan Document and the Advances made under the Credit Agreement will not violate any Requirements of Law, the Borrower’s certificate of incorporation or by-laws, or any material contractual restriction binding on or affecting the Borrower or any of its properties.

4. No approval or authorization or other action by, and no notice to or filing with, any governmental agency or regulatory body or other third person is required in connection with the due execution and delivery of any Loan Document and the performance, validity and enforceability of any Loan Document.

5. Except as described in Section 4.01(e) of the Credit Agreement, no action, suit, investigation, litigation, or proceeding, including, without limitation, any Environmental Action, affecting the Borrower or any of its Significant Subsidiaries before any court, government agency or arbitrator is pending or, to

D-5

my knowledge, threatened, that is reasonably likely to have a Material Adverse Effect.

6. Neither the Borrower nor any of its Significant Subsidiaries is an “investment company”, or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company”, as such terms are defined in the Investment Company Act of 1940, as amended (the “1940 Act”). Neither the making of any Advances, the application of the proceeds or repayment thereof by the Borrower nor the consummation of the other transactions contemplated by the Credit Agreement will violate any provision of the 1940 Act or any rule, regulation or order of the Securities and Exchange Commission thereunder.

The opinion set forth above in the last sentence of paragraph 2 above is subject to the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditor’s rights generally and to general principles of equity, including (without limitation) concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether considered in a proceeding in equity or at law.)

I express no opinion as to (i) Section 8.05 of the Credit Agreement; (ii) the effect of the law of any jurisdiction (other than the State of New York) wherein any Lender may be located which limits the rates of interest which may be charged or collected by such Lender; and (iii) whether a Federal or state court outside of the State of New York would give effect to the choice of New York law provided for in the Credit Agreement.

This opinion letter has been rendered solely for your benefit in connection with the Credit Agreement and the transactions contemplated thereby and may not be used, circulated, quoted, relied upon or otherwise referred to by any other person (other than your respective counsel, auditors and any regulatory agency having jurisdiction over you or as otherwise required pursuant to legal process or other requirements of law) for any other purpose without my prior written consent; provided that, any person that becomes a Lender after the date hereof may rely on the opinions expressed in this opinion letter as though addressed to such person. I undertake no responsibility to update or supplement this opinion in response to changes in law or future events or circumstances.

Very truly yours,

David C. House

Counsel for American Electric Power Company, Inc.
