 EXEMPT FACILITIES LOAN AGREEMENT dated as of July 1, 2009 (the “Agreement”)
between PENNSYLVANIA ECONOMIC DEVELOPMENT FINANCING AUTHORITY (the “Issuer”) and ALLEGHENY ENERGY SUPPLY COMPANY, LLC (together with permitted successors and assigns, the “Company”). 
 I. Background, Definitions, Representations and Findings. 
 Section 1.1 Background Pursuant to the Pennsylvania Economic Development Financing Law (Act No. 102, approved August 23, 1967, P.L. 251, as amended) (the “Act”), the Greene
County Industrial Development Authority has authorized and approved the Project Facilities (as defined herein) and the financing thereof by the Issuer through the issuance of the Issuer’s Exempt Facilities Revenue Bonds, Series 2009 (Allegheny
Energy Supply Company, LLC Project) in the original aggregate principal amount of $235,000,000 (the “Bonds”). The Company proposes to construct certain emissions control facilities at the three-unit, 1,710-megawatt, coal-fired
Hatfield’s Ferry Power Station (the “Plant”) in Greene County, Pennsylvania. 
 The Company has requested the
Issuer to issue Bonds to finance a portion of the cost of certain “pollution control facilities” for purposes of the Act at the Plant, which facilities are more fully described in Exhibit A (the “Project Facilities”). The Project
Facilities will be owned by the Company, a Delaware limited liability company. The Bonds will be issued under a Trust Indenture dated as of the date hereof (the “Indenture”) between the Issuer and The Bank of New York Mellon Trust Company,
N.A., as trustee (the “Trustee”). The Company and the Issuer are entering into this Agreement in order to provide for the issuance of the Bonds and the loan of the proceeds of the Bonds to the Company. 
 The obligation of the Company to repay the loan of the proceeds of the Bonds made pursuant hereto will be evidenced by the Company’s
Exempt Facilities Note (Pennsylvania Economic Development Financing Authority) Series 2009 in the principal amount of $235,000,000 (the “Note”) issued to the Trustee as the assignee of the Issuer under the Indenture. Nothing herein shall
require the Company to maintain any credit facility. 
 The Issuer and the Company intend that substantially all of the Project
Facilities constitute or will constitute “pollution control facilities” for purposes of the Act and solid waste disposal facilities for the purposes of the Internal Revenue Code of 1986, as amended (the “Code”), so that interest
on the Bonds will not be included in gross income of the holders thereof for federal income tax purposes under the Code (except for such holders who are “substantial users” of the Project Facilities or “related persons” as
provided in Section 147(a) of the Code).

 II. The Project Facilities. 
 Section 2.1 Acquisition of Project Facilities. The Company (a) has or will have acquired, constructed, installed and equipped the Project Facilities substantially in all material respects
in accordance with the description thereof in Exhibit A attached hereto and applicable law, (b) has procured or caused to be procured or will procure or cause to be procured all permits and licenses necessary for the prosecution of any and
all work on the Project Facilities, and (c) has paid or will pay when due all costs and expenses incurred in connection with such acquisition, construction, installation, equipping and improvement from funds made available therefor in
accordance with this Agreement or otherwise. It is understood the Company owns or will own or leases or will lease the Project Facilities and that any contracts made by the Company with respect thereto and any work to be done by the Company on the
Project Facilities are made or done by the Company, as applicable, on its own behalf and not as agent or contractor for the Issuer. 
  

 6 

 Section 2.2 Additions and Changes to Project Facilities. Subject to the
provisions of Section 4.11 and Section 4.12, the Company may, at its option and at its own cost and expense, at any time and from time to time, revise the description of the Project Facilities in Exhibit A attached hereto and/or make
such additions, deletions and changes to the Project Facilities as it, in its discretion, may deem to be desirable for its uses and purposes, provided that (i) any such additions and changes shall, when made, constitute part of the Project
Facilities for purposes of this Agreement, (ii) the Company shall supplement the information contained in Exhibit A attached hereto by filing with the Issuer and the Trustee such supplemental information as is necessary to reflect such
additions, deletions and changes so that the Issuer will be reasonably able to ascertain the nature and cost of the facilities included in the Project Facilities and covered by this Agreement, (iii) such additions, deletions and changes will
not result in a Misuse of Bond Proceeds, and (iv) if an addition, deletion or change is substantial in relation to the Project Facilities, the Company shall have first obtained and filed with the Issuer and the Trustee an opinion of Bond
Counsel to the effect that such addition, deletion or change is authorized or permitted under the Act and will not adversely affect the exclusion from gross income of interest on the Bonds under the Code. In any case, the Company shall obtain the
Issuer’s approval of the addition to the Project Facilities of any material changes to the proposed facilities or any other material changes not generally described or contemplated in Exhibit A attached hereto on the date of delivery of
this Agreement, which approval shall not be unreasonably withheld, and the Company shall delete any facilities from the Project Facilities if such deletion is necessary to avoid a Misuse of Bond Proceeds or to maintain the exclusion from gross
income of interest on the Bonds under the Code. 
 Section 2.3 Issuance of Bonds; Application of Proceeds. To
provide funds to make the Loan for purposes of paying Project Costs, the Issuer will issue the Bonds in the aggregate principal amount of $235,000,000. The Bonds will be issued pursuant to the Indenture and will bear interest, mature and be subject
to redemption all as set forth therein. The Company hereby approves the terms and conditions of the Indenture and the Bonds, and the terms and conditions under which the Bonds will be issued, sold and delivered. 
 The proceeds from the sale of the Bonds (including any bond discount) shall be loaned to the Company pursuant to Section 3.1 and such
proceeds (net of any bond discount) shall be paid over to the Trustee for deposit in the Project Fund as provided in the Indenture. Pending disbursement pursuant to Section 2.4, the proceeds of the Bonds so deposited in the Project Fund,
together with any investment earnings thereon, shall constitute a part of the Trust Estate and shall be subject to the lien of the Indenture pursuant to the granting clauses therein as security for the obligations described in such granting clauses,
and to such end the Company hereby grants to the Trustee as security for such obligations a security interest in all of the Company’s right, title and interest in and to the Project Fund. 
 Section 2.4 Disbursements from Project Fund. Subject to the provisions below, disbursements from the Project Fund shall be made
to reimburse or pay the Company, another Affiliate or any Person designated by the Company, for Project Costs. The Company agrees that the sums so disbursed from the Project Fund will be used only for the payment of Project Costs, and will not be
used for any other purpose. 
  

 7 

 Any disbursements from the Project Fund for the payment of the Project Costs shall be made
by the Trustee only upon the written order of an Authorized Representative of the Company delivered to the Trustee. Each such written order shall be substantially in the form of the disbursement request attached hereto as Exhibit B and shall be
consecutively numbered and accompanied by a statement in reasonable detail listing the Project Costs to be paid to any contractors, materialmen or suppliers or incurred by the Company for which it is to be reimbursed. Any disbursement for any item
which is inconsistent with the information statement filed by the Issuer in connection with the issuance of the Bonds as required by Section 149(e) of the Code, shall be accompanied by an opinion of a Bond Counsel to the effect that such
disbursement will not result in the interest on the Bonds becoming included in the gross income of the holders thereof for federal income tax purposes. In case any contract provides for the retention by the Company of a portion of the
contract price, there shall be paid from the Project Fund only the net amount remaining after deduction of any such portion, and only when that retained amount is due and payable, may it be paid from the Project Fund. 
 Section 2.5 Company Required to Pay Costs in Event Project Fund Insufficient. If moneys in the Project Fund are not sufficient
to reimburse the Company for all Project Costs, the Company will not be entitled to any reimbursement for excess expense from the Issuer, the Trustee or any Bondholder; nor shall the Company be entitled to any abatement, diminution or postponement
of the Loan Payments. 
 Section 2.6 Completion. When the Company certifies to the Trustee and the Issuer that the
Project Facilities have been completed, any amount then remaining in the Project Fund shall be reduced to cash and delivered by the Trustee in accordance with the provisions of the Indenture. 
 Section 2.7 Investment and Use of Fund Moneys. At the written request of an Authorized Representative of the Company, any moneys
held as part of the Bond Fund (except moneys representing principal of, or premium, if any, or interest on, any Bonds which are deemed paid under Section 16.01 of the Indenture) or the Project Fund shall be invested or reinvested by the Trustee
as provided in Section 8.02 of the Indenture. The Issuer and the Company each hereby covenants that it will restrict that investment and reinvestment and the use of the proceeds of the Bonds in such manner and to such extent, if any, as may be
necessary, after taking into account reasonable expectations at the time of delivery of and payment for the Bonds, so that the Bonds will not constitute arbitrage bonds under Section 148 of the Code. 
 Any Authorized Representative of the Issuer having responsibility for issuing the Bonds is authorized and directed, alone or in conjunction
with an Authorized Representative of the Company and/or any other officer, partner, employee or agent of or consultant to the Issuer or the Company, to give an appropriate certificate of the Issuer pursuant to Section 148 of the Code, for
inclusion in the transcript of proceedings for the issuance of the Bonds, setting forth the reasonable expectations of the Issuer regarding the amount and use of the proceeds of the Bonds and the facts, estimates and circumstances on which those
expectations are based, all as of the Issue Date. The Company shall provide the Issuer with, and the Issuer’s certificate may be based on, a certificate of the Authorized Representative of the Company or other appropriate officer, partner,
employee or agent of or consultant to the Company setting forth the reasonable

  

 8 

 
expectations of the Company on the Issue Date regarding the amount and use of the proceeds of the Bonds and the facts, estimates and circumstances on which they are based. 
 Section 2.8 Rebate Fund. The Company agrees to make such payments to the Trustee as are required of the Company under
Section 6.05 of the Indenture. The obligation of the Company to make such payments shall remain in effect and be binding upon the Company notwithstanding the release and discharge of the Indenture. 
 III. Loan By Issuer; Loan Payments; Other Payments 
 Section 3.1 Loan by Issuer. Upon the terms and conditions of this Agreement, the Issuer will make the Loan to the Company on the Issue Date in a principal amount equal to the aggregate
principal amount of the Bonds. The Loan shall be deemed fully advanced upon deposit of the proceeds of the Bonds (net of any bond discount) in the Bond Fund and the Project Fund pursuant to Section 2.3. 
 Section 3.2 Loan Payments. In consideration of the issuance, sale and delivery of the Bonds by the Issuer, the Company hereby
agrees to pay to the Trustee for the account of the Issuer Loan Payments in such amounts and manner so as to enable the Trustee to make payment of the principal of, premium, if any, on and accrued interest on the Bonds as the same shall become due
and payable whether by acceleration, redemption or otherwise in accordance with the terms of the Indenture; provided, however, that the obligation of the Company to make any Loan Payments hereunder shall be reduced by the amount of any reduction
under the Indenture of the amount of the corresponding payment required to be made by the Issuer thereunder in respect of the principal of or premium or interest on the Bonds and shall be reduced to the extent that other moneys on deposit with the
Trustee are available for such purpose and a credit in respect thereof has been granted pursuant to the Indenture. Pursuant to the Indenture, the Issuer directs the Trustee to apply such Loan Payments in the manner provided in the Indenture.
Whenever payment or provision for payment has been made in respect of the principal or redemption price of and interest on all of the Bonds, the Loan Payments shall be deemed paid in full. 
 The obligation of the Company to make the Loan Payments directly to the Trustee, as the assignee of the Issuer under the Indenture, shall be
evidenced by the Company’s Note substantially in the form of Exhibit C hereto, which shall be delivered concurrently with the delivery by the Issuer of the Bonds. 
 Section 3.3 Additional Payments. The Company shall pay as Additional Payments hereunder: (a) to the Issuer, the Issuer’s Fee on the Issue Date and any and all costs and expenses
(including reasonable legal fees and expenses) incurred or to be paid by the Issuer in connection with the issuance and delivery of the Bonds or otherwise related to actions taken by the Issuer under this Agreement or the Indenture or any amendment
thereof, supplement thereto or consent or waiver thereunder, including without limitation any annual charge made by a rating agency to maintain a rating on the Bonds; (b) to the Local Entity, the Local Entity’s fee on the Issue Date and
any and all costs and expenses incurred or to be paid by the Local Entity in connection with the Project Facilities; and (c) to the Trustee, the reasonable fees, charges and

  

 9 

 
expenses of the Trustee and its agents (including reasonable legal fees and expenses) for acting as such under the Indenture. 
 Section 3.4 Obligations Unconditional. The obligations of the Company to make Loan Payments and Additional Payments shall be
absolute and unconditional, and the Company shall make such payments without abatement, diminution or deduction regardless of any cause or circumstances whatsoever including without limitation any defense, set-off, recoupment or counterclaim which
the Company may have or assert against the Issuer, the Trustee or any other Person, whether express or implied, or any duty, liability or obligation arising out of or connected with this Agreement, it being the intention of the parties that the
payments required of the Company hereunder will be paid in full when due without any delay or diminution whatsoever. Loan Payments required to be paid by or on behalf of the Company hereunder shall be received by the Issuer or the Trustee as net
sums and the Company agrees to pay or cause to be paid all charges against or which might diminish such net sums.

member, director, officer, employee or agent of the Issuer or the Trustee may become subject, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise directly or indirectly out of (a) any loss or damage to
property or injury to or death of or loss by any person that may be occasioned by any cause whatsoever pertaining to the construction, maintenance, operation and use of the Project Facilities; (b) any breach or default on the part of the
Company in the performance of any covenant or agreement of the Company under this Agreement or the Note or any related document, or arising from any act or failure to act by the Company or any of its agents, contractors, servants, employees or
licensees; (c) the authorization, issuance and sale of the Bonds, or the provision of any information or certification furnished in connection therewith concerning the Bonds, the Project Facilities or the Company (including, without limitation,

employees (collectively, the “Indemnitees”) harmless from and against any and all claims, liabilities, losses, damages, fines, penalties and expenses, including out-of-pocket expenses, incidental expenses, reasonable legal fees and
expenses, and the reasonable costs and expenses of defending against any such claim (“Losses”) that may be imposed on, incurred by or asserted against, the Indemnitees or any of them for following any instruction or other direction upon
which the Trustee is authorized to rely pursuant to the terms of this Agreement, the Bonds, the Note or the Indenture. In addition to and not in limitation of the immediately preceding sentence, the Company also agrees to indemnify and hold the
Indemnitees and each of them harmless from and against any and all Losses that may be imposed on, incurred by or asserted against the Indemnitees or any of them in connection with or arising out of the Trustee’s performance under this
Agreement, the Bonds or the Indenture, or in collecting under the Note, except in any case as a result of the gross negligence, willful misconduct or bad faith of the Trustee. 
 In case any action or proceeding is brought against the Issuer or the Trustee in respect of which indemnity may be sought hereunder, the
party seeking indemnity promptly shall give notice of that action or proceeding to the Company, and the Company upon receipt of that notice shall have the obligation and the right to assume the defense of the action or proceeding; provided that
failure of a party to give that notice shall not relieve the Company from any of its obligations under this Section unless (and then only to the extent) that failure prejudices the defense of the action or proceeding by the Company. At its own
expense, an indemnified party may employ separate counsel and participate in the defense. The Issuer or the Trustee, as the case may be, will cooperate with the Company, at the Company’s expense, with respect to its assumption of the defense of
any such action or proceeding, and will take such reasonable actions as are requested of it by the Company, at the Company’s expense, in connection therewith. Company shall not be liable for any settlement made without its consent, which shall
not be unreasonably withheld. The Company shall not approve any settlement involving the Trustee without the Trustee’s prior written consent, which shall not be unreasonably withheld.

 Section 4.11 Tax Covenants of Company and Issuer. The Company covenants and
represents that it will at all times do and perform all acts and things necessary or desirable and within its reasonable control in order to assure that interest paid on the Bonds shall not be includable in the gross income of any holder thereof for
federal income tax purposes, unless such holder is a “substantial user” of the Project Facilities or a “related person” of such a user within the meaning of Section 147(a) of the Code. The Company also covenants and
represents that it shall not take or omit to take, or permit to be taken on its behalf, any actions which, if taken or omitted, would adversely affect the excludability from the gross income of the holder of interest paid on the Bonds for federal
income tax purposes. The Issuer and the Company mutually covenant for the benefit of the Bondholders that they will not use the proceeds of the Bonds, any moneys derived, directly or indirectly, from the use or investment thereof or any other moneys
on deposit in any fund or account maintained in respect of the Bonds (whether such moneys were derived from the proceeds of the sale of the Bonds or from other sources) in a manner which would cause the Bonds to be treated as “arbitrage
bonds” within the meaning of Section 148 of the Code. 
 Section 4.12 Further Tax Covenants of Company.
The Company further represents and covenants as follows: 
 (a) Action to Maintain Tax-Exempt Status. The Company will
take such actions as shall be necessary or desirable, from time to time and within its reasonable control, to cause all of the representations and warranties in this Section to remain true and correct during such periods as shall be necessary to
maintain the exclusion of interest paid on the Bonds from the gross income of the holders thereof for federal income tax purposes (other than a holder who is a “substantial user” of the Project Facilities or a “related person” as
those terms are used in Section 147(a) of the Code), pursuant to the requirements of the Code. 
 (b) Operation as Solid
Waste Disposal Facilities. As long as the Company (or its lessee or transferee) is required to operate or cause to be operated the Project Facilities under Section 4.2, the Company (or its lessee or transferee) shall operate or cause to be
operated the Project Facilities as “solid waste disposal facilities” within the meaning of Section 142(a)(6) of the Code. 
 (c) Ninety-five Percent Capital Costs Test. The Company will spend not less than 95% of the net proceeds of the Bonds for capital costs of land or property of a character subject to allowance for

structure (other than a building), or (iv) an existing structure and equipment thereof, then the

  

 15 

 
Company will, within two years of the later of the Issue Date or the date the Company acquires such building or structure, incur Rehabilitation Expenditures in an amount at least equal to
(x) 15% of the portion of the cost of acquiring all existing buildings and equipment thereof which is financed with net proceeds of the Bonds, plus (y) 100% of the portion of the cost of acquiring all existing structures (other than a
building) and equipment thereof which is financed with net proceeds of the Bonds.

Facilities. The Company will not use any portion of the proceeds of the Bonds to provide any portion of the Project Facilities to be used for a private or commercial golf course, country club, massage parlor, tennis club, skating facility
(including roller skating, skateboard and ice skating), racquet sports facility (including any handball or racquetball court), hot tub facility, suntan facility or racetrack. The Company will not use any proceeds of the Bonds to provide any

 (h) Lease or Transfer of Project Facilities. In connection with any lease or transfer by the Company of the Project Facilities
financed with Bond proceeds, the Company will require that the lessee or transferee and all Related Persons with respect to such lessee or transferee will not violate the covenants set forth in this Section.

(in addition to the amounts allowed under Sections 148(c) and (d) of the Code and subject to the yield adjustment provisions of Treasury Regulations §1.148-5(C)) of the proceeds of the Bonds will be invested in higher yielding
investments. 
 At no time will any funds constituting gross proceeds of the Bonds be used to acquire investments
at other than fair market value within the meaning of the applicable Treasury Regulations pertaining to, or in any other fashion as would constitute failure of compliance with, Section 148 of the Code. Investments or deposits in certificates of
deposit or pursuant to investment contracts shall not be made without compliance, at or prior to such investment or deposit, with the requirements of Treasury Regulations Section 1.148-5(d)(6)(ii) and (iii), respectively, or with any successor

 (k) Notice. The Company shall provide a written statement signed by its Authorized Representative to the Issuer and the Trustee reasonably promptly upon the Company’s becoming aware of a violation of any of the covenants set

required by Section 2.8, the Company will pay to or for the account of the Issuer all amounts needed to comply with the requirements of Section 148 of the Code, concerning arbitrage bonds, including Section 148(f), which requires

not limited to funds representing the proceeds of the Bonds or income from the investment thereof or any other particular source.

facilities serviced thereby; or 
 (b) changes in the economic availability of raw materials, operating supplies, or facilities

 (c) all or a substantial portion of the Project Facilities have been damaged or destroyed to such an extent that it is not practicable or
desirable to rebuild, repair or restore the Project Facilities; or 
 (d) as a result of any changes in the Constitution of the
Commonwealth of Pennsylvania or the Constitution of the United States of America or by legislative or administrative action (whether state or federal) or by final decree, judgment or order of any court or administrative body (whether state or

facilities being served by such Project Facilities for a period of at least six consecutive months; or 
 (f) the Company
permanently has terminated operations at the Project Facilities. 
 To exercise such option, the Company shall, within 90 days

will deliver the funds required for such redemption, which date shall be not more than 90 days from the date such notice is mailed and shall make arrangements satisfactory to the Trustee for the giving of the required notice of redemption.

 The amount payable by the Company in the event of its exercise of the option granted in this Section shall be the sum of
(i) an amount of money which, when added to the moneys and investments held to the credit of the Bond Fund, will be sufficient to pay, or provide for the payment of, the redemption price of Bonds on the redemption date, such amount to be paid
to the Trustee, plus (ii) an amount of money equal to the Additional Payments accrued and to accrue until actual final payment and redemption of the Bonds, such amount or applicable

accrue may be met if provisions satisfactory to the Trustee and the Issuer are made for paying those amounts as they accrue. 
 Section 5.3 Special Mandatory Redemption. The Company shall deliver or cause to be delivered to the Trustee the moneys needed to redeem the Bonds in accordance with the special mandatory redemption provisions set forth in the
Bonds and the Indenture. Whenever the Bonds are subject to special mandatory redemption pursuant to the Indenture, the Company will cooperate with the Issuer and the Trustee in effecting such redemption.

may agree to in writing; provided that if the failure is other than the payment of money and is of such nature that it can be corrected but not within the applicable period, such failure shall not constitute an Event of Default so long as the

 (c) The
Company shall (i) apply for or consent to the appointment of a receiver, trustee, liquidator or custodian or the like of itself or of its property, or (ii) admit in writing its inability to pay its debts generally as they become due, or

insolvency proceeding, or corporate action shall be taken by it for the purpose of effecting any of the foregoing, or (vi) have instituted against it, without the application, approval or consent of the Company, a proceeding in any court of
competent jurisdiction, under any law relating to bankruptcy, insolvency, reorganization or relief of debtors, seeking in respect of the Company an

  

 19

trustee, receiver, liquidator or custodian or the like of the Company or of all or any substantial part of their assets, or other like relief in respect thereof under any bankruptcy or insolvency law, and the same shall (A) result in the entry
of an order for relief or any such adjudication or appointment or (B) remain unvacated, undismissed and undischarged for a period of 90 days; 
 (d) Any representation or warranty made by the Company herein or any statement in any report, certificate, financial statement or other instrument furnished in connection with this Agreement shall at any
time prove to have been false or misleading in any material respect when made or given; and 
 (e) For any reason the Bonds are
declared due and payable by acceleration in accordance with Section 9.02 of the Indenture. 
 The declaration of an Event
of Default under paragraph (e) above, and the exercise of remedies upon any such declaration, shall be subject to any applicable limitations of federal bankruptcy law affecting or precluding that declaration or exercise during the pendency of
or immediately following any bankruptcy, liquidation or reorganization proceedings. 
 Section 6.2 Remedies on
Default. 
 (a) Whenever an Event of Default shall have happened and be subsisting uncured, any one or more of the following
remedial steps may be taken: 
 (1) If acceleration of the principal amount of the Bonds has been declared
pursuant to Section 9.02 of the Indenture, the Trustee, by notice in writing to the Company, shall declare all Loan Payments and amounts due on the Note to be immediately due and payable, whereupon the same shall become immediately due and
payable; and 
 (2) The Issuer or the Trustee may pursue any and all remedies now or hereafter existing at law or
in equity to collect all amounts then due and thereafter to become due under this Agreement or to enforce the performance and observance of any other obligation or agreement of the Company under this Agreement and the Note. 
 (b) The Company covenants that, in case it shall fail to pay or cause to be paid any Loan Payments as and when the same shall become due and
payable whether at maturity or by acceleration or otherwise, then, upon demand of the Trustee, the Company will pay to the Trustee the whole amount that then shall have become due and payable hereunder; and, in addition thereto, such further amounts
as shall be sufficient to cover the reasonable costs and expenses of collection, including a reasonable compensation to the Trustee, its agents and counsel, and any expenses or liabilities incurred by the Issuer or the Trustee, including counsel
fees and expenses. In case the Company shall fail forthwith to pay such amounts upon such

  

 20 

 
demand, the Trustee shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid. 
 (c) In case there shall be pending proceedings for the bankruptcy or reorganization of the Company under the federal bankruptcy laws or any
other applicable law, or in case a receiver or trustee shall have been appointed for the benefit of the creditors or the property of the Company, the Trustee shall be entitled and empowered, by intervention in such proceedings or otherwise, to file
and prove a claim or claims for the whole amount due hereunder, including interest owing and unpaid in respect thereof, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee allowed in such judicial proceedings relative to the Company, its creditors or its property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and
to distribute the same after the deduction of its charges and expenses. Any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized to make such payments to the Issuer or the Trustee, and to pay to the Issuer or the
Trustee any amount due it for compensation and expenses, including counsel fees and expenses incurred by it up to the date of such distribution. 
 (d) Notwithstanding the foregoing, the Trustee shall not be obligated to take any step which in its opinion will or might cause it to expend money or otherwise incur liability unless and until a
satisfactory indemnity bond has been furnished to the Trustee at no cost or expense to the Trustee. Any amounts collected as Loan Payments or applicable to Loan Payments and any other amounts which would be applicable to payment of Debt Service
collected pursuant to action taken under this Section shall, after the deduction of the Trustee’s charges and expenses, be paid into the Bond Fund and applied in accordance with the provisions of the Indenture or, if the Outstanding Bonds have
been paid and discharged in accordance with the provisions of the Indenture, shall be paid as provided in Section 5.02(d) of the Indenture for transfers of remaining amounts in the Bond Fund. 
 (e) The provisions of this Section are subject to the further limitation that the annulment by the Trustee of its declaration pursuant to
Section 9.02 of the Indenture that all of the Bonds are immediately due and payable also shall constitute an annulment of any corresponding declaration made pursuant to Section 6.2(a)(1); provided that no such waiver or rescission shall
extend to or affect any subsequent or other default or impair any right consequent thereon. 
 Section 6.3 Remedies Not
Exclusive. No remedy conferred upon or reserved to the Issuer or the Trustee by this Agreement is intended to be exclusive of any other available remedy or remedies, including without limitation the remedies provided in the Act, but each and
every such remedy shall be cumulative and shall be in addition to every other remedy given under this Agreement, or now or hereafter existing at law or in equity. No delay or omission to exercise any right or power accruing upon any default shall
impair that 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. In order to entitle the Issuer or the Trustee to exercise any remedy
reserved to it in this Article, it shall not be necessary to give any notice, other than any notice required by law or for which express provision is made herein.

 Section 6.4 Payment of Legal Fees and Expenses. If an Event of Default should
occur and the Issuer or the Trustee should incur expenses, including reasonable attorneys’ fees and expenses, in connection with the enforcement of this Agreement, the Indenture, the Note or the collection of sums due hereunder or thereunder,
the Company shall reimburse the Issuer and the Trustee, as applicable, for the expenses so incurred, upon demand. 
 Section 6.5
No Waiver. No failure by the Issuer or the Trustee to insist upon the strict performance by the Company of any provision hereof or of the Note shall constitute a waiver of their right to strict performance and no express waiver shall be
deemed to apply to any other existing or subsequent right to remedy the failure by the Company to observe or comply with any provision hereof. 
 The Trustee shall not waive an Event of Default under Section 6.1(f) without the prior written consent of the Issuer. 
 Section 6.6 Notice of Default. The Company shall immediately notify the Trustee and the Issuer in writing if it becomes aware of the occurrence of any Event of Default hereunder or of any
fact, condition or event which, with the giving of notice or passage of time or both, would become an Event of Default.

provision of this Agreement is determined by a court to be invalid or unenforceable, such determination shall not affect any other provision hereof, each of which shall be construed and enforced as if the invalid or unenforceable portion were not

opinion of Bond Counsel to be a “project” as such term is defined in the Act after such assignment; (iv) such assignment shall not, in the opinion of Bond Counsel, have an adverse effect on the exclusion from gross income for federal
income tax purposes of interest on the Bonds; (v) the assignee shall not be a Disqualified Contractor and shall provide a written certification to such effect to the Trustee and the Issuer; and (vi) if the assignee is other than an
Affiliate of the Company, consent by the Issuer, which consent shall not be unreasonably withheld. Subject to the foregoing, the terms “Issuer,” “Company” and “Trustee” shall, where the context requires, include the

 EXHIBIT A 
 DESCRIPTION OF PROJECT FACILITIES 
 The Company owns
Hatfield’s Ferry Generating Station (the “Station”), a steam electric generating station located in Masontown, Greene County, Pennsylvania. The Station consists of three pulverized coal-fired power generating units with a nominal
maximum operational generation capacity of 1,710 megawatts. The Company is installing three limestone forced oxidation flue gas desulfurization units (the “Scrubbers”) to remove sulfur dioxide (SO2) from the flue gas of the three
generating units (the “Project Facilities”). The Company has undertaken construction and installation of the Project Facilities to provide additional capacity for the disposal and processing of certain waste material generated during
operation of the Scrubbers. The Project Facilities include equipment, structures and related systems and facilities functionally related and subordinate thereto that will be used to collect, store, treat, transfer, process or dispose of such waste
material. The principal components of the Project Facilities are absorber towers that operate to remove and collect waste materials generated by the removal of SO2 from the boiler flue gas, oxidation facilities, and facilities for dewatering,
handling and disposing of the waste.

 FORM OF DISBURSEMENT REQUEST 
 STATEMENT
NO.             REQUESTING DISBURSEMENT OF FUNDS FROM PROJECT FUND PURSUANT TO SECTION 2.4 OF THE EXEMPT FACILITIES LOAN AGREEMENT DATED AS OF JULY 1, 2009 (“LOAN
AGREEMENT”) BETWEEN PENNSYLVANIA ECONOMIC DEVELOPMENT FINANCING AUTHORITY (“ISSUER”) AND ALLEGHENY ENERGY SUPPLY COMPANY, LLC (“COMPANY”). 
 The terms used herein shall have the meanings specified for such terms in or pursuant to the Loan Agreement. Pursuant to Section 2.4 of the Loan Agreement, the undersigned Authorized Representative
of the Company hereby requests and authorizes the Trustee to pay to the Company or to the Person(s) listed on the Disbursement Schedule attached hereto out of the moneys deposited in the Project Fund the aggregate sum of
$             to reimburse the Company or to pay such Person(s), as indicated in the Disbursement Schedule, for the items of Project Cost listed in the Disbursement Schedule. Such
Payee(s) may be (i) the Company in the case of work done by Company personnel and in the case of reimbursement for payments previously made by the Company for Project Costs (other than payments made by way of set-off of mutual claims between
the Company and the payee), (ii) the Trustee in the case of a requisition for payment of interest on the Bonds during acquisition, construction, installation, equipment and improvement of the Project Facilities, (iii) the United States of
America in respect of any amount required to be paid pursuant to Section 148(f) of the Code and (iv) any other Person designated by the Company for Project Costs incurred by such Person associated with the issuance of the Bonds. All such
payments shall be made by check or wire transfer in accordance with payment instructions contained in the Disbursement Schedule and the Trustee shall have no duty or obligation to authenticate such payment instructions or the authorization thereof.

 In connection with the foregoing request and authorization, the undersigned hereby certifies that: 
 (a) Each item for which disbursement is requested hereunder is due, is an item of incurred Project Cost properly reimbursable or payable out
of the Project Fund in accordance with the terms and conditions of the Loan Agreement, and none of those items has formed the basis for any disbursement heretofore made from the Project Fund. 
 (b) Each such item is or was necessary or appropriate in connection with the acquisition, construction, installation, equipment and/or
improvement of the Project Facilities. 
 (c) Each such item is as described in the information statement filed by the Issuer in
connection with the issuance of the Bonds (as defined in the Loan Agreement), as required by Section 149(e) of the Code; provided that if any such item is not as described in that

  

 B-1 

 
information statement, attached hereto is an opinion of Bond Counsel that such disbursement will not result in the interest on the Bonds becoming included in the gross income of the holders
thereof for federal income tax purposes. 
 (d) The reimbursement or payment of the Project Costs requisitioned hereby will
comply with the restrictions contained in Section 2.4, Section 4.11 and Section 4.12 of the Loan Agreement. 
 (e) This statement and all exhibits hereto, including the Disbursement Schedule, shall constitute full warrant, protection and authority to the Trustee for its actions taken pursuant hereto.

 EXEMPT FACILITIES NOTE

 (PENNSYLVANIA ECONOMIC DEVELOPMENT FINANCING AUTHORITY) 
 SERIES 2009 
 This Note is issued pursuant to an Exempt
Facilities Loan Agreement dated as of July 1, 2009 (the “Agreement”) by and between the Pennsylvania Economic Development Financing Authority (the “Issuer”) and the Company (as hereinafter defined) relating to the financing
of certain facilities (the “Project Facilities”) at the Hatfield’s Ferry Power Station located in Greene County, Pennsylvania. This Note is the Note referred to in the Agreement. Reference is made to the Agreement for provisions for
the prepayment hereof and the acceleration of the maturity hereof. All of the terms, conditions, covenants, representations and warranties of the Agreement are incorporated herein by reference as if same were fully set forth at length herein. Each
capitalized term not otherwise defined herein shall have the meaning given to such term in the Agreement. 
 ALLEGHENY ENERGY
SUPPLY COMPANY, LLC (the “Company”), a Delaware limited liability company, for value received, unconditionally promises to pay to THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee (including its successors in such capacity, the
“Trustee”) under the Trust Indenture dated as of July 1, 2009 (as the same may be amended and supplemented from time to time, the “Indenture”) between the Trustee and the Issuer, the principal sum of TWO HUNDRED THIRTY-FIVE
MILLION AND 00/100 DOLLARS ($235,000,000) on July 15, 2039, and to pay (i) interest thereon from the date hereof until the payment of such principal sum has been made or provided for at a rate or rates at all times equal to the interest
rate or rates from time to time borne by the Issuer’s Exempt Facilities Revenue Bonds, Series 2009 (Allegheny Energy Supply Company, LLC Project) (the “Bonds”) and payable on each date that interest is payable on the Bonds, and
(ii) to the extent provided by law, on overdue interest at the rate or rates borne by the Bonds. 
 If the Bonds become
subject to redemption as provided therein and in the Indenture, the Company shall, as provided in the Agreement, on or before the proposed redemption date for the Bonds, pay to the Trustee the whole or appropriate portion of the unpaid principal
amount of this Note with interest accrued to the proposed redemption date, together with such premium as is necessary to pay the corresponding premium, if any, on the Bonds. Such amount shall be paid by the Company to the Trustee on the date
specified in a notice from the Trustee. 
 If, for any reason, the amounts specified above are not sufficient to make
corresponding payments of principal of, premium, if any, and interest on, all of the Bonds, when such payments are due, the Company shall pay as additional amounts due hereunder, the amounts required from time to time to make up any such deficiency.
Whenever payment or provision for payment has been made in respect of the principal or redemption price of, and

  

 C-1 

 
interest on, all of the Bonds in accordance with the Indenture, this Note shall be deemed paid in full and shall be canceled and returned to the Company. 
 All payments of principal, redemption price and interest shall be made to the Trustee at its corporate trust office designated pursuant to
the Indenture, in such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. All payments shall be made in funds which will be available no later than
10:00 a.m. on the applicable due date, and shall be in the full amount required hereunder unless the Trustee notifies the Company that it is entitled to a credit under the Agreement or the Indenture. 
 The obligations of the Company to make the payments required hereunder shall be absolute and unconditional without defense or setoff by
reason of any cause or circumstance whatsoever, including without limitation, any acts or circumstances that may constitute failure of consideration, destruction of or damage to the Project Facilities or the Plant, commercial frustration of purpose,
or failure of the Issuer to perform and observe any agreement, whether express or implied, or any duty, liability or obligation arising out of or connected with the Agreement, it being the intention of the Company and the Issuer that the payments
hereunder will be paid in full when and as due without any delay or diminution whatsoever. 
 In case one or more of the Events
of Default specified in Section 6.1 of the Agreement shall have occurred and be continuing, then and in each and every such case, the Trustee, by notice in writing to the Company, may declare the unpaid balance of this Note to be due and
payable immediately, if concurrently with or prior to such notice the unpaid principal amount of the Bonds has been declared to be due and payable, and upon any such declaration the same shall become and shall be immediately due and payable,
anything in this Note or in the Agreement to the contrary notwithstanding. 
 In case the Trustee shall have proceeded to
enforce its rights under this Note or the Agreement and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Trustee, then and in every such case the Company and the Trustee shall
be restored to their respective positions and rights hereunder, and all rights, remedies and powers of the Company and the Trustee shall continue as though no such proceeding had been taken, subject to any such adverse determination. 
 In case the Company shall fail forthwith to pay all amounts due hereunder and under the Agreement upon such demand, the Trustee shall be
entitled and empowered to institute any action or proceeding at law or in equity for the collection of the sums so due and unpaid, and may prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or
final decree against the Company and collect, in the manner provided by law out of the property of the Company, the moneys adjudged or decreed to be payable. 
 This Note shall be governed by and interpreted under the laws of the Commonwealth of Pennsylvania.

 NONDISCRIMINATION/SEXUAL HARASSMENT CLAUSE 
 During
the term of this contract, the Company agrees as to itself and each tenant of the Project Facilities controlling, controlled by or under common control with the Company (each of the Company and each such tenant, a “Contractor”) as follows:

 1. In the hiring of any employee(s) for the manufacture of supplies, performance of work, or any other activity required
under the contract or any subcontract, the Contractor, subcontractor, or any person acting on behalf of the Contractor or subcontractor shall not, by reason of gender, race, creed, or color, discriminate against any citizen of this Commonwealth who
is qualified and available to perform the work to which the employment relates. 
 2. Neither the Contractor nor any
subcontractor nor any person on their behalf shall in any manner discriminate against or intimidate any employee involved in the manufacture of supplies, the performance of work, or any other activity required under the contract on account of
gender, race, creed, or color. 
 3. Contractors and subcontractors shall establish and maintain a written sexual harassment
policy and shall inform their employees of the policy. The policy must contain a notice that sexual harassment will not be tolerated and employees who practice it will be disciplined. 
 4. Contractors shall not discriminate by reason of gender, race, creed, or color against any subcontractor or supplier who is qualified to
perform the work to which the contracts relates. 
 5. The Contractor and each subcontractor shall furnish all necessary
employment documents and records to and permit access to their books, records, and accounts by the contracting agency and the Bureau of Contract Administration and Business Development, for purposes of investigation, to ascertain compliance with
provisions of this Nondiscrimination/Sexual Harassment Clause. If the Contractor or any subcontractor does not possess documents or records reflecting the necessary information requested, the Contractor or subcontractor shall furnish such
information on reporting forms supplied by the contracting agency or the Bureau of Contract Administration and Business Development. 
 6. The Contractor shall include the provisions of this Nondiscrimination/Sexual Harassment Clause in every subcontract so that such provisions will be binding upon each subcontractor. 
 7. The Commonwealth may cancel or terminate the contract, and all money due or to become due under the contract may be forfeited for a
violation of the terms and conditions of this Nondiscrimination/Sexual Harassment Clause. In addition, the agency may proceed with debarment or suspension and may place the Contractor in the Contractor Responsibility File.

 EXHIBIT E 
 RIGHT-TO-KNOW LAW PROVISIONS 
 1. The Pennsylvania
Right-to-Know Law (hereinafter referred to as the “RTKL”), 65 P.S. §§ 67.101-3104, applies to this Exempt Facilities Loan Agreement dated as of July 1, 2009 (this “Agreement”), between Pennsylvania Economic
Development Financing Authority and Allegheny Energy Supply Company, LLC (the “Company”). For the purpose of administering the matters relating to the RTKL set forth in this Exhibit, the applicable “Commonwealth agency” as
provided in the RTKL shall be the Pennsylvania Economic Development Financing Authority, hereinafter referred to as the “Agency.” Capitalized terms used but not otherwise defined herein shall have the same meanings as in the RTKL.

 2. If the Agency needs the Company’s and each tenants’ of the Project Facilities controlling, controlled by or
under common control with the Company (each of the Company and each such tenant, a “Contractor”), assistance in any matter arising out of the RTKL, the Agency shall notify the Contractor using the legal contact information provided in this
Agreement. The Contractor, at any time, may designate a different contact for such purpose upon reasonable prior written notice to the Agency. 
 3. Upon written notification from the Agency that it requires the Contractor’s assistance in responding to a request under the RTKL for information that may be in the Contractor’s possession,
constituting, or alleged to constitute, a Public Record in accordance with the RTKL, the Contractor shall: 
  

	 	a.	Provide the Agency, within ten (10) calendar days after receipt of such notification, access to, and copies of, any document or information in the
Contractor’s possession arising out of this Agreement that the Agency reasonably believes may be a Public Record under the RTKL (“Requested Information”), to permit Agency to evaluate whether such Requested Information is, in fact, a
Public Record within the scope of the subject RTKL information request; provided, however, that providing such Requested Information not previously in the Agency’s possession shall not be considered an admission by the Contractor that such
records are Public Records under the RTKL; and 

  

	 	b.	Provide such other assistance as the Agency reasonably may request, in order to comply with the RTKL. 

 If the Contractor fails to provide the Requested Information within ten (10) calendar days after receipt of such request, the Contractor shall
indemnify and hold the Agency harmless for any damages, penalties, detriment or harm that the Agency may incur under the RTKL as a result of the Contractor’s failure, including any statutory damages assessed against the Agency. 
 4. If the Contractor considers the Requested Information not to be a Public Record, due to the inclusion of trade secret, confidential
proprietary information, or any other reason for exemption from production as a Public Record under the RTKL, the Contractor shall provide a

  

 E-1 

 
written statement to the Agency within ten (10) days of receipt of Agency request for the Requested Information. This statement shall be signed by a representative of the Contractor,
explaining why the Contractor considers the Requested Information exempt from public disclosure. 
 5. If such a written
statement is timely provided, the Agency will rely upon it in denying a RTKL request for the information. Provided, however, that if the Agency reasonably determines that such written statement is patently flawed or the Requested Information is, on
its face, clearly not protected from disclosure under the RTKL, the Contractor shall, subject to its rights of appeal, provide the Requested Information within five (5) business days. 
 6. The Contractor shall be entitled to challenge or appeal of any decision of the Agency, Office of Open Records (“OOR”) or any
applicable court mandating the release of any record to the public which the Contractor believes is not properly subject to disclosure under the RTKL; provided, however, that (i) the Contractor shall be solely responsible for all costs related
to such action; and (ii) the Contractor shall indemnify and hold harmless the Agency from and against any and all damages, penalties, detriment or harm that the Agency may incur under the RTKL as a result of such action, including any statutory
damages assessed against the Agency. If the Contractor does not appeal or is not successful after final appeal from a determination by the OOR or Pennsylvania courts, the Contractor agrees to waive all rights or remedies that may be available to it
as a result of the Agency’s subsequent disclosure of Requested Information pursuant to such a decision by the OOR or Pennsylvania courts. The Agency will reimburse the Contractor for any costs associated with complying with this provision, but
only to the extent allowed under the fee schedule established by the OOR, or as otherwise provided by the RTKL, if the fee schedule is inapplicable. 
 7. Notwithstanding the foregoing, nothing set forth herein is intended, nor shall it be construed, to expand the Contractor’s obligations, or the Agency’s authority, beyond those obligations and
authority, respectively, as are set forth in the RTKL, and the sole remedy for any failure by the Contractor to perform any obligation arising hereunder, or under the RTKL, shall be limited to those specifically provided for pursuant to the RTKL and
shall not constitute a default or event of default under this Agreement.

each such Advance not to exceed such Lender’s Unused Commitment at such time; provided that after giving effect to any Borrowing, (i) the Total Revolving Outstandings shall not exceed the Facility, and (ii) the aggregate
Outstanding Amount of the Advances of any Lender plus such Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations, shall not exceed such Lender’s Commitment. Each Borrowing shall be in an aggregate amount of
$2,000,000 or an integral multiple of $1,000,000 in excess thereof and shall consist of Advances of the same Type made simultaneously by the Lenders ratably according to their Commitments. Within the limits of each Lender’s Unused Commitment in
effect from time to time, the Borrower may borrow under this Section 2.01(a), prepay pursuant to Section 2.06(a) and reborrow under this Section 2.01(a). 
 (b) Letters of Credit. Subject to the terms and conditions set forth herein, (i) each Issuing Bank agrees, in reliance upon the agreements of the other Lenders set forth in Section 2.03,
(A) from time to time on any Business Day during the period from the Closing Date until the Letter of Credit Expiration Date, to make L/C Credit Extensions for the account of the Borrower or its Subsidiaries, and to amend or extend Letters of
Credit previously issued by it, in accordance with Section 2.03(a)(i) and (ii), and (B) to honor drawings under the Letters of Credit issued by it; and (ii) the Lenders severally agree to participate in Letters of Credit issued for
the account of the Borrower or its Subsidiaries and any L/C Borrowings thereunder; provided that after giving effect to any L/C Credit Extension with respect to any Letter of Credit, (x) the Total Revolving Outstandings shall not exceed
the Facility and (y) the aggregate Outstanding Amount of the Advances of any Lender, plus such Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations, shall not exceed such Lender’s Commitment. Each request by
the Borrower for the issuance of, or an amendment to increase the amount of, any Letter of Credit shall be deemed to be a representation by the Borrower that the L/C Credit Extension so requested complies with the conditions set forth in the proviso
to the preceding sentence. Within the foregoing limits, and subject to the terms and conditions hereof, the Borrower’s ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrower may, during the foregoing period,
obtain Letters of Credit to replace Letters of Credit that have expired or that have been drawn upon and reimbursed. 
 (c)
Letters of Credit Generally. (i) No Issuing Bank shall issue any Letter of Credit if the expiry date of such requested Letter of Credit would occur after the Letter of Credit Expiration Date, unless all the Lenders have approved such
expiry date; provided that in no event shall the expiry date of any requested Letter of Credit occur on or after the Business Day immediately preceding the third anniversary of the Closing Date. 
  

					
		 	32	 	AESC Credit Agreement

 (ii) No Issuing Bank shall be under any Obligation to make any L/C Credit
Extension if: 
 (A) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms
purport to enjoin or restrain such Issuing Bank from issuing such Letter of Credit, or any Applicable Law to such Issuing Bank or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction
over such Issuing Bank shall prohibit, or request that the Issuing Bank refrain from, the issuance of Letters of Credit generally or such Letter of Credit in particular or shall impose upon such Issuing Bank with respect to such Letter of Credit any
restriction, reserve or capital requirement (for which such Issuing Bank is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon such Issuing Bank any unreimbursed loss, cost or expense which was not
applicable on the Closing Date and which such Issuing Bank in good faith deems material to it; 
 (B) the making
of such L/C Credit Extension would violate any Applicable Laws; 
 (C) except as otherwise agreed by the
Administrative Agent and such Issuing Bank, such Letter of Credit is in an initial face amount less than $100,000; 
 (D) such L/C Credit Extension is to be denominated in a currency other than Dollars; 
 (E) such L/C
Credit Extension contains any provisions for automatic reinstatement of the stated amount after any L/C Borrowing thereunder; or 
 (F) a default of any Lender’s obligations to fund under Section 2.03 exists, or any Lender is then a Defaulting Lender, unless such Issuing Bank has entered into satisfactory arrangements with
the Borrower or such Lender to eliminate such Issuing Bank’s risk with respect to such Lender. 
 (iii) No
Issuing Bank shall amend any Letter of Credit if such Issuing Bank would not be permitted at such time to make such L/C Credit Extension in its amended form under the terms hereof. 
 (iv) No Issuing Bank shall be under the obligation to amend any Letter of Credit if (A) such Issuing Bank would have no
obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not accept the proposed amendment to such Letter of Credit. 
 SECTION 2.02. Making the Advances. (a) Except as otherwise provided in Section 2.03, each Borrowing shall be made on
notice, given by the Borrower not later than 2:00 p.m. (New York City time) on the third Business Day prior to the date of the proposed Borrowing in the case of a Borrowing consisting of Eurodollar Rate Advances, or not later than 11:00 a.m. (New
York City time) on the date of the proposed Borrowing in the case of a Borrowing consisting of Base Rate Advances, to the Administrative Agent, which shall give to each Lender prompt notice thereof by telecopier or electronic mail. Each such notice
of a Borrowing (a “Notice of Borrowing”) shall be by telephone, confirmed immediately in writing,

  

					
		 	33	 	AESC Credit Agreement

 
or telecopier or electronic mail, in substantially the form of Exhibit B, specifying therein the requested (i) date of 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, initial Interest Period for each such Advance. Each Lender shall, before 12:00 noon (New York City time) on the date of
such Borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent’s Account, in immediately available funds, such Lender’s ratable portion of such Borrowing in
accordance with the respective Commitment of such Lender and the other Lenders. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent shall
make such funds available to the Borrower, by crediting the Borrowing Account; provided, however, that the Administrative Agent shall first make a portion of such funds equal to the aggregate principal amount of any L/C Borrowings made by any
Issuing Bank and by any Lender, as the case may be, and outstanding on the date of such Borrowing, plus interest accrued and unpaid thereon to and as of such date, available to such Issuing Bank or such other Lender, as the case may be, for
repayment of such L/C Borrowing. 
 (b) Anything in subsection (a) above to the contrary notwithstanding, (i) the
Borrower may not select Eurodollar Rate Advances for any Borrowing if the aggregate amount of such Borrowing is less than $2,000,000 or if the obligation of the Lenders to make Eurodollar Rate Advances shall then be suspended pursuant to
Section 2.11 or 2.12 and (ii) the Advances may not be outstanding as part of more than fifteen separate Borrowings. 
 (c) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing that the Borrower has specified in the related Notice of Borrowing is to be comprised of 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 Article
III, including any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or redeployment 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) Subject to the Administrative Agent
giving prompt notice of the relevant Notice of Borrowing received by the Administrative Agent to the Lenders, unless the Administrative Agent shall have received notice from any Lender prior to the date of the Borrowing requested under such Notice
of Borrowing that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent
on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If and to the extent that such
Lender shall not have so made such ratable portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay or pay to the Administrative Agent forthwith on demand such corresponding amount and to pay interest
thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid or paid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at such time under
Section

  

					
		 	34	 	AESC Credit Agreement

 
2.07 to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall pay to the Administrative Agent such corresponding amount, such
amount so paid shall constitute such Lender’s Advance as part of such Borrowing for all purposes. 
 (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. 
 SECTION 2.03. Issuance of
Letters of Credit; Drawings and Reimbursements; Auto-Extension Letters of Credit; Funding of Participations. (a) Procedures for Issuance and Amendment of Letters of Credit; Auto-Extension Letters of Credit. (i) Each Letter of
Credit shall be issued or amended, as the case may be, upon the request of the Borrower delivered to an Issuing Bank (with a copy to the Administrative Agent) in the form of a Letter of Credit Application, appropriately completed and signed by a
Responsible Officer of the Borrower. Such Letter of Credit Application must be received by such Issuing Bank and the Administrative Agent not later than 2:00 p.m. (New York City time) at least one (1) Business Day (or such later date and time
as the Administrative Agent and the Issuing Bank may agree in a particular instance in their sole discretion) prior to the proposed issuance date or date of amendment, as the case may be. In the case of a request for an initial issuance of a Letter
of Credit, such Letter of Credit Application shall specify in form and detail satisfactory to the respective Issuing Bank: (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount
thereof; (C) the expiry date thereof (which date shall be not later than the earlier of (1) the date which is twelve (12) months after the proposed issuance date and (2) the Letter of Credit Expiration Date (or such later date as
may be agreed by the Lenders in accordance with Section 2.01(c)(i)); (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text
of any certificate to be presented by such beneficiary in case of any drawing thereunder; and (G) such other matters as such Issuing Bank may require. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of
Credit Application shall specify in form and detail satisfactory to the respective Issuing Bank (w) the Letter of Credit to be amended; (x) the proposed date of amendment thereof (which shall be a Business Day); (y) the nature of the
proposed amendment; and (z) such other matters as such Issuing Bank may require. Additionally, the Borrower shall furnish to each Issuing Bank and the Administrative Agent such other documents and information pertaining to such requested Letter
of Credit issuance or amendment, including any Issuer Documents, as each such Issuing Bank or the Administrative Agent may require. 
 (ii) Promptly after receipt of any Letter of Credit Application, the Issuing Bank will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received a copy of such Letter of Credit Application
from the Borrower and, if not, such Issuing Bank will provide the Administrative Agent with a copy thereof. Unless such Issuing Bank has received written notice from any Lender, the Administrative Agent or the Borrower, at least one
(1) Business Day prior to the requested date of issuance or amendment of the applicable Letter of Credit, that one or more applicable

  

					
		 	35	 	AESC Credit Agreement

 
conditions contained in Article III shall not then be satisfied, then, subject to the terms and conditions hereof, such Issuing Bank shall, on the requested date, make an L/C Credit Extension for
the account of the Borrower or enter into the applicable amendment, as the case may be, in each case in accordance with such Issuing Bank’s usual and customary business practices. Immediately upon the making of each L/C Credit Extension, each
Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from such Issuing Bank a risk participation in such L/C Credit Extension in an amount equal to the product of such Lender’s Pro Rata Share times
the amount of such L/C Credit Extension. 
 (iii) If the Borrower so requests in any applicable Letter of Credit Application,
the Issuing Bank may, in its sole and absolute discretion, agree to make an L/C Credit Extension that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”);
provided that any such Auto-Extension Letter of Credit must permit such Issuing Bank to prevent any such extension at least once in each twelve-month period (commencing with the date of issuance of such Letter of Credit) or upon notice to
such Issuing Bank by the Administrative Agent or the Borrower of an Insolvency Proceeding with respect to the Borrower or any Material Subsidiary, by giving prior notice to the beneficiary thereof not later than a day (the
“Non-Extension Notice Date”) in each such twelve-month period to be agreed upon at the time such Letter of Credit is issued. Unless otherwise directed by such Issuing Bank, the Borrower shall not
be required to make a specific request to such Issuing Bank for any such extension. Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) such Issuing Bank to permit the
extension of such Letter of Credit at any time to an expiry date not later than the Letter of Credit Expiration Date (or such later date as may be agreed by the Lenders in accordance with Section 2.01(c)(i)); provided, however, that such
Issuing Bank shall not permit any such extension if (A) such Issuing Bank has determined that it would not be permitted, or would have no obligation at such time to issue such Letter of Credit in its revised form (as extended) under the terms
hereof (by reason of the provisions of Section 2.01(c)(i), or otherwise), or (B) it has received notice (which may be by telephone or in writing) on or before the day that is five Business Days before the Non-Extension Notice Date
(1) from the Administrative Agent that the Required Lenders have elected not to permit such extension or (2) from the Administrative Agent or any Lender that one or more of the applicable conditions specified in Section 3.02 is not
then satisfied, and in each such case directing such Issuing Bank not to permit such extension. 
 (iv) Promptly after its
delivery of any Letter of Credit or any amendment to a Letter of Credit to an advising bank with respect thereto or to the beneficiary thereof, such Issuing Bank will also deliver to the Borrower and the Administrative Agent a true and complete copy
of such Letter of Credit or amendment thereof. 
 (b) Drawings and Reimbursements; Funding of Participations.
(i) Upon receipt from the beneficiary of any Letter of Credit of any notice of a drawing under such Letter of Credit, the Issuing Bank shall notify the Administrative Agent and the Borrower thereof. Not later than 11:00 a.m. (New York City
time) on the date of any payment by such Issuing Bank under a Letter of Credit (each such date, an “Honor Date”), the Borrower shall reimburse such Issuing Bank through the Administrative Agent in an amount equal to the
amount of such drawing. If the Borrower fails to so reimburse such Issuing Bank by such time, the Administrative Agent shall promptly notify each Lender of the Honor Date, the amount of the

  

					
		 	36	 	AESC Credit Agreement

 
unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Lender’s Pro Rata Share thereof. In such event, the Borrower shall be deemed to have
requested a Borrowing of Base Rate Advances to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.01 for the principal amount of Base Rate Advances,
but subject to the other conditions set forth in Section 2.01 and the conditions set forth in Section 3.02 (other than the delivery of a Notice of Borrowing). Any notice given by such Issuing Bank or the Administrative Agent pursuant to
this Section 2.03(b) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice. 
 (ii) Each Lender (including the Lender acting as Issuing Bank) shall upon any notice pursuant to Section 2.03(b)(i) make funds
available to the Administrative Agent for the account of such Issuing Bank at the Administrative Agent’s Account in an amount equal to its Pro Rata Share of the Unreimbursed Amount not later than 1:00 p.m. (New York City time) on the Business
Day specified in such notice by the Administrative Agent, whereupon, subject to the provisions of Section 2.03(b)(iii), each Lender that so makes funds available shall be deemed to have made a Base Rate Advance to the Borrower in such amount.
The Administrative Agent shall remit the funds so received to such Issuing Bank. 
 (iii) With respect to any Unreimbursed
Amount that is not fully refinanced by a Borrowing of Base Rate Advances because the conditions set forth in Section 3.02 cannot be satisfied or for any other reason, the Borrower shall be deemed to have incurred from the Issuing Bank an L/C
Borrowing in the amount of the Unreimbursed Amount that is not so refinanced, which L/C Borrowing shall be due and payable on demand (together with interest) and shall bear interest at a rate equal to the sum of (A) the Base Rate in effect from
time to time, plus (B) the Applicable Margin in effect from time to time, plus (C) 2% per annum. In such event, each Lender’s payment to the Administrative Agent for the account of such Issuing Bank pursuant
to Section 2.03(b)(ii) shall be deemed payment in respect of its participation in such L/C Borrowing and shall constitute an L/C Advance from such Lender in satisfaction of its participation obligation under this Section 2.03. 

(iv) Until each Lender funds its Advance or L/C Advance pursuant to this Section 2.03(b) to reimburse such Issuing Bank for any
amount drawn under any Letter of Credit, interest in respect of such Lender’s Pro Rata Share of such drawing shall be solely for the account of such Issuing Bank. 
 (v) Each Lender’s obligation to make Advances or L/C Advances to reimburse any Issuing Bank for amounts drawn under Letters of Credit, as contemplated by this Section 2.03(b), shall be
irrevocable, absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Issuing Bank, the Borrower or any other
Person for any reason whatsoever; (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such making of an L/C Advance shall relieve or otherwise
impair the obligation of the Borrower to reimburse any Issuing Bank for the amount of any payment made by the Issuing Bank under any Letter of Credit, together with interest as provided herein. 
  

					
		 	37	 	AESC Credit Agreement

 (vi) If any Lender fails to make available to the Administrative Agent for the account of
any Issuing Bank any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.03(b) by the time specified in Section 2.03(b)(ii), such Issuing Bank shall be entitled to recover from such Lender
(acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to such Issuing Bank at a rate per annum
equal to the Federal Funds Rate from time to time in effect. A certificate of such Issuing Bank submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this Section 2.03(b)(vi) shall be conclusive
absent manifest error. 
 (c) Repayment of Participations. (i) At any time after an Issuing Bank has made a payment
under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.03(b), if the Administrative Agent receives for the account of such Issuing Bank any payment in
respect of the related Unreimbursed Amount or interest thereon (whether directly from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such
Lender its Pro Rata Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s L/C Advance was outstanding) in the same funds as those received by the Administrative Agent.

 (ii) If any payment received by the Administrative Agent for the account of an Issuing Bank pursuant to
Section 2.03(b)(i) is required to be returned under any of the circumstances described in Section 2.12 (including pursuant to any settlement entered into by such Issuing Bank in its discretion), each Lender shall pay to the Administrative
Agent for the account of such Issuing Bank its Pro Rata Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to
the Federal Funds Rate from time to time in effect. 
 (d) Role of Issuing Bank. Each Lender and the Borrower agree that,
in paying any drawing under a Letter of Credit, each Issuing Bank shall not have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by any Letter of Credit) or to ascertain or inquire
as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of the Issuing Bank, the Administrative Agent nor any of the respective correspondents, participants or assignees of
such Issuing Bank shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the
absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or Letter of Credit Application. The Borrower hereby assumes
all risks of the acts or omissions of any beneficiary or transferee with respect to any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower from pursuing such rights and
remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the Issuing Bank, the Administrative Agent, nor any of the respective correspondents, participants or assignees of such Issuing Bank shall be
liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.03(j); provided, however, that anything in such clauses to the contrary

  

					
		 	38	 	AESC Credit Agreement

 
notwithstanding, the Borrower may have a claim against an Issuing Bank, and such Issuing Bank may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to
consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by such Issuing Bank’s willful misconduct or gross negligence or such Issuing Bank’s willful failure to pay under any Letter of Credit after
the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, an Issuing Bank may accept documents that
appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and such Issuing Bank shall not be responsible for the validity or sufficiency of any instrument
transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason. 
 (e) Cash Collateral. (i) Upon the occurrence and during the continuance of any Event of Default, at the request of the
Administrative Agent, (A) if an Issuing Bank has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing, or (B) if, as of the Letter of Credit Expiration Date (or, if the
expiry date of such Letter of Credit is after the Letter of Credit Expiration Date (as may be agreed by the Lenders in accordance with Section 2.01(c)(i)), as of such later expiry date), any Letter of Credit for any reason remains outstanding
and partially or wholly undrawn, the Borrower shall immediately Cash Collateralize the then Outstanding Amount of all L/C Obligations (in an amount equal to such Outstanding Amount determined as of the date of such L/C Borrowing or the Letter of
Credit Expiration Date (or such later date as may be agreed by the Lenders in accordance with Section 2.01(c)(i)), as the case may be). 
 (ii) At the request of the Administrative Agent (the Administrative Agent hereby agreeing to make such request upon a request from any Issuing Bank), if (A) there is at any time a Defaulting Lender,
and (B) (I) one or more Letters of Credit are then outstanding or (II) an Issuing Bank has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing that is then outstanding,
then, in any such case, the Borrower shall immediately (x) repay to each Issuing Bank such Defaulting Lender’s Pro Rata Share of such L/C Borrowing, together with accrued interest thereon through the date of such repayment and
(y) Cash Collateralize such Defaulting Lender’s Pro Rata Share of the aggregate undrawn amount of all outstanding Letters of Credit. 
 (iii) The Borrower hereby grants to the Administrative Agent, for the benefit of each Issuing Bank and the Lenders, a security interest in all such cash, deposit accounts and all balances held in the Cash
Collateral Account and all proceeds of the foregoing. Upon the drawing of any Letter of Credit for which funds are on deposit as Cash Collateral, such funds shall be applied, to the extent permitted under Applicable Law, to reimburse each Issuing
Bank. 
 (f) Applicability of ISP and UCP. Unless otherwise expressly agreed by an Issuing Bank and the Borrower upon
issuing an L/C Credit Extension, (i) the rules of the ISP shall apply to each Standby Letter of Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary Credits, as most recently published by the International Chamber
of Commerce at the time of issuance, shall apply to each Trade Letter of Credit. 
  

					
		 	39	 	AESC Credit Agreement

 (g) Conflict with Issuer Documents. In the event of any conflict between the terms
hereof and the terms of any Issuer Document, the terms hereof shall control. 
 (h) Letters of Credit Issued for
Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any Obligations of, or is for the account of, a Subsidiary, the Borrower shall be obligated to reimburse the Issuing Bank hereunder for any
and all drawings under such Letter of Credit. The Borrower hereby acknowledges that the L/C Credit Extensions for the account of Subsidiaries inure to the benefit of the Borrower, and that the Borrower’s business derives substantial benefits
from the businesses of such Subsidiaries. 
 (i) Letter of Credit Reports. Each Issuing Bank shall furnish (A) to
the Administrative Agent on the first Business Day of each month a written report summarizing issuance and expiration dates of L/C Credit Extensions issued during the preceding month and drawings during such month under each Letter of Credit and
(B) to the Administrative Agent and each Lender on the first Business Day of each calendar quarter a written report setting forth the average daily aggregate L/C Obligations during the preceding calendar quarter of all Letters of Credit.

 (j) Obligations Absolute. The obligation of the Borrower to reimburse each Issuing Bank for each drawing under each
Letter of Credit and to repay each L/C Borrowing shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following: 
 (i) any lack of validity or enforceability of such Letter of Credit, this Agreement or any other Financing Document;

 (ii) the existence of any claim, counterclaim, setoff, defense or other right that the Borrower or any
Subsidiary may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), such Issuing Bank or any other Person, whether in connection with
this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction; 
 (iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged,
fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of
Credit; 
 (iv) any payment by such Issuing Bank under such Letter of Credit against presentation of a draft or
certificate that does not strictly comply with the terms of such Letter of Credit (so long as such draft or certificate substantially complies with such terms); or any payment made by such Issuing Bank under such Letter of Credit to any Person
purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit; or 
  

					
		 	40	 	AESC Credit Agreement

 (v) any other circumstance or happening whatsoever, whether or not similar
to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower. 
 The Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it pursuant to Section 2.03(a)(iv) and, in the event of any claim of noncompliance
with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the Issuing Bank. The Borrower shall be conclusively deemed to have waived any such claim against the Issuing Bank and its correspondents unless such
notice is given as aforesaid. 
 (k) Liability. The Borrower assumes all risks of the acts or omissions of any
beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither any Issuing Bank, any of its Affiliates, nor any of its respective officers, directors, agents, employees, attorneys and advisors shall be
liable or responsible for: (i) the use that may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any
endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) payment by such Issuing Bank against presentation of documents that do not comply with the terms of any
Letter of Credit, including failure of any documents to bear any reference or adequate reference to any Letter of Credit; or (iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit, except that
the Borrower shall have a claim against such Issuing Bank, and such Issuing Bank shall be liable to the Borrower, to the extent of any direct, but not consequential, damages suffered by the Borrower that the Borrower proves were primarily caused by
(A) such Issuing Bank’s willful misconduct or gross negligence as determined in a final, non-appealable judgment by a court of competent jurisdiction in determining whether documents presented under any Letter of Credit comply with the
terms thereof or (B) such Issuing Bank’s willful failure to make lawful payment under any Letter of Credit after the presentation to it of a draft and certificates strictly complying with the terms and conditions of any Letter of Credit.
In furtherance and not in limitation of the foregoing, such Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

 SECTION 2.04. Repayment of Advances. The Borrower shall repay to the Administrative Agent for the ratable account of
the Lenders on the Final Maturity Date the aggregate principal amount of all Advances which are then outstanding.

such Issuing Bank, and upon such payments, the obligations of such Lender hereunder with respect to such Unused Commitment which have been terminated shall, by the provisions hereof, be released and discharged; provided, however, that such
Lender’s rights and obligations provided in Section 8.16 with respect to such Unused Commitment which have been terminated shall survive such release and discharge as to matters occurring prior to such date. 
 SECTION 2.06. Prepayments. (a) Optional. The Borrower may, upon at least one Business Day’s notice in the case of
Base Rate Advances and three Business Days’ notice in the case of Eurodollar Rate Advances, in each case to the Administrative Agent stating the proposed date and aggregate principal amount of the prepayment, and if the notice is given the
Borrower shall, prepay the outstanding aggregate 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 aggregate principal amount
prepaid; provided that (i) each partial prepayment shall be in an aggregate principal amount of $2,000,000 or an integral multiple of $1,000,000 in excess thereof and (ii) if any prepayment of a Eurodollar Rate Advance is made on a
date other than the last day of an Interest Period for the Advance, the Borrower shall also pay any amounts owing pursuant to Section 8.04(d). 
 (b) Other Amounts. Concurrently with any prepayment of Advances under this Section 2.06, the Borrower shall pay to the applicable Lender or Issuing Bank all accrued fees, costs and expenses,
accrued interest thereon, if any, and any other amounts due under the Financing Documents in respect of the principal amount of the Advances or L/C Borrowings so prepaid, including pursuant to Section 8.04(e).

 SECTION 2.07. Interest. (a) Scheduled Interest. The Borrower shall pay
interest on the unpaid principal amount of each Advance owing to each Lender from the date of such Advance until such principal amount shall be paid in full, at the following rates per annum: 
 (i) Base Rate Advances. During such periods as such Advance is a Base Rate Advance, a rate per annum equal at
all times to the sum of (A) the Base Rate in effect from time to time plus (B) the Applicable Margin in effect from time to time, payable in arrears each Quarterly Date during such periods and on the date such Base Rate Advance
shall be Converted or paid in full. 
 (ii) Eurodollar Rate Advances. 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 (A) the Eurodollar Rate for such Interest Period for such Advance plus (B) the Applicable Margin in
effect from time to time, 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 date of such
Interest Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full. 
 (b) Default Interest.
Upon the occurrence and during the continuance of an Event of Default, the Borrower shall pay interest on (i) the unpaid and overdue principal amount of each Advance owing to each Lender, payable in arrears on the dates referred to in clause
(a)(i) or (a)(ii) above and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on such Advance pursuant to clause (a)(i) or (a)(ii) above and (ii) to the
fullest extent permitted by Applicable Law, the amount of any interest, fee or other amount payable by the Borrower hereunder that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, payable in
arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid, in the case of interest, on the Type of Advance on
which such interest has accrued pursuant to clause (a)(i) or (a)(ii) above and, in all other cases, on Base Rate Advances pursuant to clause (a)(i) above.

Section 2.11(a)(ii) or a notice of selection of an Interest Period pursuant to the terms of the definition of “Interest Period”, in each case from the Borrower, the Administrative Agent shall give notice to the Borrower and
each Lender of the applicable Interest Period and the applicable interest rate determined by the Administrative Agent for purposes of clause (a)(i) or (a)(ii) above. 
 SECTION 2.08. Fees. (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of the Lenders a commitment fee from the date hereof, in the case of each
Initial Lender, and from the effective date specified in either a joinder agreement pursuant to Section 2.16 or the Assignment and Acceptance pursuant to which it became a Lender in the case of each other Lender, until the Final Maturity Date,
commencing on the Closing Date, and payable quarterly in arrears on the first Business Day after the end of each Quarterly Date and on the Final Maturity Date, at the Commitment Fee Rate on the average daily Unused Commitment of such Lender during
such fiscal quarter; provided, however, that no commitment fee shall accrue on the Unused Commitment of a Defaulting Lender during any period that such Lender shall be a Defaulting Lender. 
  

					
		 	43	 	AESC Credit Agreement

 (b) Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the
account of each Lender in accordance with its Pro Rata Share a Letter of Credit fee (the “Letter of Credit Fee”) for each Letter of Credit equal to the Applicable Margin for Eurodollar Rate Advances in effect
from time to time multiplied by the daily maximum amount available to be drawn under such Letter of Credit (whether or not such maximum amount is then in effect under such Letter of Credit). Letter of Credit Fees shall be (i) computed on a
quarterly basis in arrears and (ii) due and payable on the first Business Day after the end of each Quarterly Date, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration
Date and thereafter on demand; provided, however, that no Letter of Credit Fee shall accrue on the Pro Rata Share of a Letter of Credit of a Defaulting Lender during any period that such Lender shall be a Defaulting Lender.
Notwithstanding anything to the contrary contained herein, upon the request of the Required Lenders, while any payment-related Default exists, all Letter of Credit Fees shall accrue at the Applicable Margin for Eurodollar Rate Advances
plus 2%. 
 (c) Fronting Fee and Documentary and Processing Charges Payable to Issuing Banks, Etc. The Borrower
shall pay directly to the relevant Issuing Bank for its own account a fronting fee with respect to each Letter of Credit issued hereunder in the amount to be agreed between the Borrower and the applicable Issuing Bank of the L/C Obligations (whether
or not such maximum amount is then in effect under such Letter of Credit) (the “Fronting Fee”). The Fronting Fee shall be computed on a quarterly basis in arrears and shall be due and payable on each Quarterly
Date, commencing with the first such date to occur after the issuance of such Letter of Credit, on the Letter of Credit Expiration Date and thereafter on demand. In addition, the Borrower shall, with respect to all Letters of Credit issued at its
request, pay directly to each Issuing Bank for its own account the customary issuance, presentation, amendment and other processing fees, and other standard costs and charges, of such Issuing Bank relating to letters of credit as from time to time
in effect. Such customary fees and standard costs and charges are due and payable on demand and are nonrefundable. 
 (d) The
Administrative Agent’s Fees. The Borrower shall pay to the Administrative Agent for its own account such fees as may from time to time be agreed between the Borrower and such Administrative Agent. 
 SECTION 2.09. Payments Generally; Pro Rata Treatment. (a) The Borrower shall make each payment hereunder, under the Notes and
under any Financing Document owing to any Lender Party, in full, and without condition or deduction for any counterclaim, defense, recoupment or setoff, not later than 2:00 p.m. (New York City time) on the day when due in Dollars to the
Administrative Agent at the Administrative Agent’s Account in immediately available funds, with payments being received by the Administrative Agent after such time being deemed to have been received on the next succeeding Business Day. The
Administrative Agent will promptly thereafter cause like funds to be distributed (i) if the payment by (or for the account of) the Borrower is in respect of principal, interest, commitment fees or any other Obligation then payable hereunder and
under the Notes to more than one Lender Party, to such Lender Parties for the account of their respective Applicable Lending Offices ratably in accordance with the amounts of such respective Obligations then payable to such Lender Parties and
(ii) if such payment is in respect of any Obligation then payable hereunder to one Lender

  

					
		 	44	 	AESC Credit Agreement

 
Party, to such Lender Party for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement; provided, that with respect to any
optional or mandatory prepayment, if any Lender is a Defaulting Lender at the time of any such prepayment, such prepayment of the Advances shall, if the Administrative Agent so directs at the time of making such prepayment, be applied to the
Advances of other Lenders as if such Defaulting Lender had no Advances outstanding and the outstanding Advances of such Defaulting Lender were zero until such time as the proportion (expressed as a fraction) of the principal amount outstanding of
all Advances owed to each Lender (including Defaulting Lenders) is equal to the Pro Rata Share of such Lender. Upon its acceptance of an Assignment and Acceptance and recording of the information contained therein in the Register pursuant to
Section 8.07(e), from and after the effective date of such Assignment and Acceptance, the Administrative Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender Party assignee
thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. 
 (b) All payments under this Agreement and the other Financing Documents to the Administrative Agent (whether for its own account or for the
account of any Lender Party) shall be made to such Administrative Agent. 
 (c) The Borrower hereby authorizes each Lender Party
and each of its Affiliates, if and to the extent payment owed to such Lender Party by the Borrower is not made when due hereunder or, in the case of a Lender, under its Note or Notes, to charge from time to time, to the fullest extent permitted by
law, against any or all of the Borrower’s accounts with such Lender Party or such Affiliate any amount so due. 
 (d) All
computations of interest based on the Base Rate or the Federal Funds Rate 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, fees or commissions
are payable. Each determination by the Administrative Agent of an interest rate, fee or commission hereunder shall be conclusive and binding for all purposes, absent manifest error. 
 (e) Whenever any payment hereunder or under the Notes 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 commitment fee, as the case may be; provided 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, such payment shall be made on the immediately preceding Business Day. 
 (f) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to any Lender
Party 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

  

					
		 	45	 	AESC Credit Agreement

 
Agent may, in reliance upon such assumption, cause to be distributed to each such Lender Party on such due date an amount equal to the amount then due such Lender Party. If and to the extent the
Borrower shall not have so made such payment in full to the Administrative Agent, each such Lender Party shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender Party together with interest thereon, for
each day from the date such amount is distributed to such Lender Party until the date such Lender Party repays such amount to the Administrative Agent, at the Federal Funds Rate. 
 (g) If the Administrative Agent receives funds for application to the Obligations under the Financing Documents under circumstances for
which the Financing Documents do not specify the Advances or the Facility to which, or the manner in which, such funds are to be applied, the Administrative Agent may, but shall not be obligated to, elect to distribute such funds to each Lender
Party ratably in accordance with such Lender Party’s proportionate share of the principal amount of all outstanding Advances and the L/C Obligations then outstanding, in repayment or prepayment of such of the outstanding Advances or other
Obligations owed to such Lender Party, and for application to such principal installments, as the Administrative Agent shall direct; provided that the Borrower shall not be liable to any Lender Party with respect to any such distribution by
the Administrative Agent. 
 (h) If any Lender Party shall obtain any payment (whether voluntary, involuntary, through the
exercise of any right of set-off, or otherwise), other than pursuant to Section 2.10, 2.12 or 2.13, as a result of an assignment pursuant to Section 8.07, as a result of the payment of an Amendment Fee which has been offered to or is
available to all Lender Parties on the same terms or payments made pursuant to Section 2.08(a), 2.08(b) or 2.09(a) during any period that any Lender shall be a Defaulting Lender, (a) on account of Obligations due and payable to such Lender
Party hereunder and under the Notes at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such Lender Party at such time to (ii) the aggregate amount of the
Obligations due and payable to all Lender Parties hereunder and under the Notes at such time) of payments on account of the Obligations due and payable to all Lender Parties hereunder and under the Notes at such time obtained by all the Lender
Parties at such time or (b) on account of Obligations owing (but not due and payable) to such Lender Party hereunder and under the Notes at such time in excess of its ratable share (according to the proportion of (i) the amount of such
Obligations owing to such Lender Party at such time to (ii) the aggregate amount of the Obligations owing (but not due and payable) to all Lender Parties hereunder and under the Notes at such time) of payments on account of the Obligations
owing (but not due and payable) to all Lender Parties hereunder and under the Notes at such time obtained by all of the Lender Parties at such time, such Lender Party shall forthwith purchase from the other Lender Parties such interests or
participating interests in the Obligations due and payable or owing to them, as the case may be, as shall be necessary to cause such purchasing Lender Party to share the excess payment ratably with each of them; provided that if all or any
portion of such excess payment is thereafter recovered from such purchasing Lender Party, such purchase from each other Lender Party shall be rescinded and such other Lender Party shall repay to the purchasing Lender Party the purchase price to the
extent of such Lender Party’s ratable share (according to the proportion of (i) the purchase price paid to such Lender Party to (ii) the aggregate purchase price paid to all Lender Parties) of such recovery together with an amount
equal to such Lender Party’s ratable share (according to the proportion of (i) the amount of such other Lender Party’s required repayment to (ii) the total amount so recovered

  

					
		 	46	 	AESC Credit Agreement

 
from the purchasing Lender Party) of any interest or other amount paid or payable by the purchasing Lender Party in respect of the total amount so recovered. The Borrower agrees that any Lender
Party so purchasing an interest or participating interest from another Lender Party pursuant to this Section 2.09 may, to the fullest extent permitted by Applicable Law, exercise all its rights of payment (including the right of set-off) with
respect to such interest or participating interest, as the case may be, as fully as if such Lender Party were the direct creditor of the Borrower in the amount of such interest or participating interest, as the case may be. 
 SECTION 2.10. Illegality. Notwithstanding any other provision of this Agreement, if the introduction of or any change in or in the
interpretation of any law or regulation shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any Lender or its Eurodollar Lending Office to perform its obligations hereunder to make
Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Advances hereunder, then, on notice thereof and demand therefor by such Lender to the Borrower through the Administrative Agent, (i) each Eurodollar Rate Advance will
automatically, upon such demand, Convert into a Base Rate Advance and (ii) the obligation of such Lender to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower
that such Lender has determined that the circumstances causing such suspension no longer exist; provided that, before making any such demand, such Lender agrees to use reasonable efforts (consistent with its internal policy and legal and
regulatory restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Lender or its Eurodollar Lending Office to continue to perform its obligations to make Eurodollar Rate Advances or to
continue to fund or maintain Eurodollar Rate Advances and would not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. 
 SECTION 2.11. Interest Elections. (a) Optional. (i) The Borrower may on any Business Day elect to Convert all or any portion of the Advances comprising the same Borrowing from one
Type into Advances of the other Type, and in the case of Eurodollar Rate Advances, may elect Interest Periods therefor, all as provided in this Section 2.11. The Borrower may elect different options with respect to different portions of any
Borrowing, in which case each such portion shall be allocated ratably among the Lenders in accordance with their Commitments. At no time shall the total number of different Interest Periods for all Eurodollar Rate Advances outstanding exceed ten.

 (ii) To make an election pursuant to this Section 2.11(a), the Borrower shall give the Administrative Agent prior
written notice (or telephonic notice promptly confirmed in writing) by telecopier or electronic mail (a “Notice of Conversion/Continuation”) of the Conversion or Continuation, as the case may be, (i) by 11:00 a.m. (New
York City time) on the requested date of a Conversion into Base Rate Advances and (ii) by 2:00 p.m. (New York City time) three Business Days prior to a Continuation of or Conversion into Eurodollar Rate Advances; 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), no Conversion of any Advances shall result in more separate Borrowings than permitted under Section 2.02(b) and each Conversion of Advances comprising
part of the same Borrowing shall be made ratably

  

					
		 	47	 	AESC Credit Agreement

 
among the Lenders in accordance with their Commitments. Each such Notice of Conversion/Continuation shall be irrevocable and shall specify (A) if different options are being elected with
respect to different portions of the relevant Borrowing, the portions thereof that are to be allocated to each resulting election (in which case the information to be specified pursuant to clauses (C) and (D) shall be specified for each
resulting portion); (B) the effective date of the election made pursuant to such Notice of Conversion/Continuation, which shall be a Business Day; (C) whether the resulting Borrowings are to be comprised of Base Rate Advances or Eurodollar
Rate Advances; and (D) if the resulting Borrowings are to be comprised of Eurodollar Rate Advances, the Interest Period applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of
“Interest Period”. If any such Notice of Conversion/Continuation requests that the relevant Borrowing be comprised of Eurodollar Rate Advances but does not specify an Interest Period, the Borrower shall be deemed to have selected an
Interest Period of one month. Each Notice of Conversion/Continuation shall be irrevocable and binding on the Borrower. 
 (iii)
If, on the expiration of any Interest Period in respect of any Eurodollar Rate Advances, the Borrower shall have failed to deliver a Notice of Conversion/Continuation, then, unless such Advances are repaid as provided herein, the Borrower shall be
deemed to have elected to Convert such Advances to Base Rate Advances. No Advances may be Converted into, or Continued as, Eurodollar Rate Advances if an Event of Default has occurred and is continuing, unless the Administrative Agent and the
Required Lenders shall have otherwise consented in writing. 
 (iv) Upon receipt of any Notice of Conversion/Continuation, the
Administrative Agent shall promptly notify each Lender of the details thereof and of such Lender’s ratable share of each election. 
 (b) Mandatory. (i) 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 $2,000,000, such Advances shall automatically Convert into Base Rate Advances. 
 (ii) If the Borrower shall fail to
select the duration of any Interest Period for any Eurodollar Rate Advances to be made to it in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, the Administrative Agent shall
forthwith so notify the Borrower and the Lenders, whereupon each such Eurodollar Rate Advance shall automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance. 
 (iii) Upon the occurrence and during the continuance of any Event of Default, (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. 
 SECTION 2.12. Increased Costs, Etc. (a) If, due to either (i) the introduction of or any change (other than any change by way of
imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or

  

					
		 	48	 	AESC Credit Agreement

 
regulation or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in
the cost to any Lender Party of agreeing to make or of making, funding or maintaining Eurodollar Rate Advances or of agreeing to maintain or participate in the L/C Credit Extensions or of agreeing to make or of making or funding or maintaining L/C
Credit Extensions (excluding, for purposes of this Section 2.12, any such increased costs resulting from (A) Taxes or Other Taxes (as to which Section 2.13 shall govern) and (B) changes in the basis of taxation of overall net
income or overall gross income by the United States or by the foreign jurisdiction or state under the laws of which such Lender Party is organized or has its Applicable Lending Office or any political subdivision thereof), then the Borrower shall
from time to time, upon demand by such Lender Party (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender Party additional amounts sufficient to compensate such Lender Party for such
increased cost; provided, however, that a Lender Party claiming additional amounts under this Section 2.12(a) agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a
different Applicable Lending Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost that may thereafter accrue and would not, in the reasonable judgment of such Lender Party, be otherwise
disadvantageous to such Lender Party. A certificate as to the amount of such increased cost, submitted to the Borrower by such Lender Party, shall be conclusive and binding for all purposes, absent manifest error. 
 (b) If any Lender Party determines that compliance with any law or regulation or any guideline or request from any central bank or other
Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender Party or any corporation controlling such Lender Party and that the amount of such
capital is increased by or based upon the existence of such Lender Party’s commitment to lend or to participate in the making of L/C Credit Extensions hereunder and other commitments of such type or the maintenance of or participation in the
L/C Credit Extensions (or similar contingent obligations), then, upon demand by such Lender Party or such corporation (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Administrative Agent for the account of
such Lender Party, from time to time as specified by such Lender Party, additional amounts sufficient to compensate such Lender Party in the light of such circumstances, to the extent that such Lender Party reasonably determines such increase in
capital to be allocable to the existence of such Lender Party’s commitment to lend or to participate in the L/C Credit Extensions or to the issuance or maintenance of or participation in L/C Credit Extensions. A certificate as to such amounts
submitted to the Borrower by such Lender Party shall be conclusive and binding for all purposes, absent manifest error. 
 (c)
If, with respect to any Eurodollar Rate Advances, 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 Lenders of making, funding or
maintaining their Eurodollar Rate Advances for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon (i) each such 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 until the Administrative Agent shall notify the
Borrower that such Required Lenders have determined that the circumstances causing such suspension no longer exist. 
  

					
		 	49	 	AESC Credit Agreement

 SECTION 2.13. Taxes. (a) Any and all payments by the Borrower hereunder or under
the Notes shall be made, in accordance with Section 2.09, free and clear of and without deduction for any and all present or future withholding taxes, including levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding, in the case of each Lender Party and the Administrative Agent, (i) taxes imposed on (or measured by) its overall net income, or any franchise taxes or similar taxes imposed for the privilege of carrying on a
business in corporate form (other than taxes imposed as a result of entering into this Agreement or any other Financing Document and the transactions contemplated hereby or thereby), or taxes measured by its net worth or shareholder’s capital,
by the United States, or by the jurisdiction under the laws of which such recipient is organized or in which its Applicable Lending Office is located, (ii) any branch profits taxes imposed by the United States or any similar tax imposed by any
other jurisdiction in which the Applicable Lending Office of any Lender Party is located and (iii) withholding taxes excluded pursuant to clause (e) of this Section 2.13 (all such non-excluded taxes, including levies, imposts,
deductions, charges, withholdings and liabilities in respect of payments hereunder or under the Notes being hereinafter referred to as “Covered Taxes”). If the Borrower shall be required by law to deduct any Covered Taxes
from or in respect of any sum payable hereunder or under any Note to any Lender Party or the Administrative Agent, (A) the sum payable by the Borrower shall be increased as may be necessary so that after the Borrower and the Administrative
Agent have made all required deductions (including deductions applicable to additional sums payable under this Section 2.13) such Lender Party or the Administrative Agent, as the case may be, receives an amount equal to the sum it would have
received had no such deductions been made, (B) the Borrower shall make all such deductions and (C) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with Applicable Law.

 (b) In addition, the Borrower shall pay any present or future stamp, documentary, excise, property, intangible, mortgage
recording or similar taxes, charges or levies that arise from any payment made hereunder or under the Notes or from the execution, delivery or registration of, performance under, or otherwise with respect to, this Agreement or any other Financing
Document, but excluding all other U.S. federal taxes other than withholding taxes (hereinafter referred to as “Other Taxes”). If revised disclosure regulations under Section 6011 of the Code are issued which modify the
definition of a “reportable transaction” so that it does not include a transaction where the issuer of a debt instrument provides an indemnity for taxes, in addition to withholding taxes imposed on interest paid on the debt
instrument, for purposes of subsections (a) and (b) of this Section 2.13, the terms “Covered Taxes” and “Other Taxes” shall include all such taxes (other than any taxes described in clauses (i),
(ii) and (iii) of Section 2.13(a) above), whether or not collected by way of withholding. 
 (c) The Borrower
shall indemnify each Lender Party and the Administrative Agent for and hold them harmless against the full amount of Covered Taxes and Other Taxes, and for the full amount of taxes of any kind imposed by any jurisdiction on amounts payable under
this Section 2.13, imposed on or paid by such Lender Party or the Administrative Agent (as the case may be) and any liability (including penalties, additions to tax, interest and reasonable expenses) arising therefrom or with respect thereto.
This indemnification shall be made within 30 days from the date such Lender Party or the Administrative Agent (as the case may be) makes written demand therefor. 
  

					
		 	50	 	AESC Credit Agreement

 (d) As soon as practicable (but in no event later than 90 days) after the date of any
payment of Covered Taxes, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment. Excluding payments made by the Administrative
Agent, in the case of any payment hereunder or under the Notes by or on behalf of the Borrower through an account or branch outside the United States or by or on behalf of the Borrower by a payor that is not a United States person, if the Borrower
determines that no Covered Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Administrative Agent, at such address, an opinion of counsel acceptable to the Administrative Agent stating
that such payment is exempt from Covered Taxes. For purposes of subsections (d) and (e) of this Section 2.13, the terms “United States” and “United States person” shall have the meanings
specified in Section 7701 of the Code. 
 (e) Each Lender Party organized under the laws of a jurisdiction outside the
United States shall, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender Party and on the date of the Assignment and Acceptance pursuant to which it becomes a Lender Party in the case of each
other Lender Party, and from time to time thereafter as requested in writing by the Borrower (but only so long thereafter as such Lender Party remains lawfully able to do so), provide each of the Administrative Agent and the Borrower with two duly
completed copies of (i) Internal Revenue Service Form W-8ECI, or any successor form thereto, certifying that the payments received from the Borrower hereunder are effectively connected with such Lender Party’s conduct of a trade or
business in the United States; or (ii) Internal Revenue Service Form W-8BEN, or any successor form thereto, certifying that such Lender Party is entitled to benefits under an income tax treaty to which the United States is a party which reduces
the rate of withholding tax on payments of interest; or (iii) Internal Revenue Service Form W-8BEN or any successor form thereto, together with a certificate stating that (1) the Lender Party is not a bank for purposes of Code
Section 881(c)(3)(A), or the obligation of the Borrower hereunder is not, with respect to such Lender Party, pursuant to a loan agreement entered into in the ordinary course of its trade or business, within the meaning of that Section;
(2) the Lender Party is not a 10% shareholder of the Borrower within the meaning of Code Section 871(h)(3) or 881(c)(3)(B); and (3) the Lender Party is not a controlled foreign corporation that is related to the Borrower within the
meaning of Code Section 881(c)(3)(C); or (iv) such other governmental forms as may be applicable to the Lender Party, including Forms W-8IMY or W-8EXP, which will reduce the rate of withholding tax on payments of interest. Each Lender
Party organized under the laws of the United States that is not a corporation shall, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender Party and on the date of the Assignment and Acceptance
pursuant to which it becomes a Lender Party in the case of each other Lender Party, and from time to time as requested in writing by the Borrower, provide each of the Administrative Agent and the Borrower with two duly completed copies of Internal
Revenue Service Form W-9. Each Lender Party shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Lender Party (but only to the extent such Lender Party is lawfully able to do so). Each such
Lender Party shall promptly notify the Borrower at any time that it determines that it is no longer in a position to provide any previously

  

					
		 	51	 	AESC Credit Agreement

 
delivered certificate to the Borrower (or any other form of certification adopted by the Internal Revenue Service for such purpose). If the forms provided by a Lender Party at the time such
Lender Party first becomes a party to this Agreement indicate a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Covered Taxes unless and until such Lender Party provides
the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Covered Taxes for periods governed by such forms; provided, however, that if, at the effective
date of the Assignment and Acceptance pursuant to which a Lender Party becomes a party to this Agreement, the Lender Party assignor was entitled to payments under subsection (a) of this Section 2.13 in respect of United States withholding
tax with respect to interest paid at such date, then, to such extent, the term “Covered Taxes” shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Covered Taxes)
United States withholding tax, if any, applicable with respect to the Lender Party assignee on such date. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to
compute the tax payable and information required by the applicable Internal Revenue Service form (or related certificate described above), that the applicable Lender Party reasonably considers to be confidential, such Lender Party shall give notice
thereof to the Borrower and shall not be obligated to include in such form or document such confidential information. 
 (f)
Notwithstanding the foregoing, for any period with respect to which a Lender Party has failed to provide the Borrower with the appropriate form described in subsection (e) above (other than if such failure is due to a change in law
occurring after the date on which a form originally was required to be provided or if such form otherwise is not required under subsection (e) above), such Lender Party shall not be entitled to indemnification under subsection (a) or
(c) of this Section 2.13 with respect to Covered Taxes imposed by the United States by reason of such failure; provided that should a Lender Party become subject to Covered Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such steps as such Lender Party shall reasonably request to assist such Lender Party to recover such Covered Taxes. 
 (g) Any Lender Party claiming any additional amounts payable pursuant to this Section 2.13 agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions)
to change the jurisdiction of its Eurodollar Lending Office or Domestic Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the
reasonable judgment of such Lender Party, be otherwise disadvantageous to such Lender Party. 
 (h) If any Lender Party
determines, in its sole discretion, that it has actually and finally realized, by reason of a refund, deduction or credit of any Covered Taxes paid or reimbursed by the Borrower pursuant to subsection (a) or (c) above in respect of
payments under the Financing Documents, a current monetary benefit that it would otherwise not have obtained, and that would result in the total payments under this Section 2.13 exceeding the amount needed to make such Lender Party whole, such
Lender Party shall pay to the Borrower, with reasonable promptness following the date on which it actually realizes such benefit, an amount equal to the lesser of the amount of such benefit or the amount of such excess, in each case net of all
out-of-pocket expenses in securing such refund, deduction or credit. 
  

					
		 	52	 	AESC Credit Agreement

 SECTION 2.14. Evidence of Debt. (a) Each Lender Party shall maintain in
accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender Party resulting from the Advances or L/C Credit Extensions and/or L/C Borrowings owing to such Lender Party from time to time,
including the amounts of principal and interest payable and paid to such Lender Party from time to time hereunder. The Borrower agrees that upon notice by any Lender Party to the Borrower (with a copy of such notice to the Administrative Agent) to
the effect that a promissory note or other evidence of indebtedness is required or appropriate in order for such Lender Party to evidence (whether for purposes of enforcement or otherwise) the Advances or L/C Borrowings owing to, or to be made by,
such Lender Party, the Borrower shall promptly execute and deliver to such Lender Party, with a copy to the Administrative Agent, a Note, in substantially the form of Exhibit A hereto, payable to the order of such Lender Party in a principal amount
equal to the Advances and/or L/C Borrowings owing to, or to be made by, such Lender Party. All references to Notes in the Financing Documents shall mean Notes, if any, issued hereunder. 
 (b) The Register maintained by the Administrative Agent pursuant to Section 8.07(e) shall include a control account, and a subsidiary
account for each Lender Party, in which accounts (taken together) shall be recorded (i) the date and amount of each Advance or L/C Advance or L/C Borrowing made hereunder (or deemed to be made hereunder), whether such Advance or L/C Borrowing
bears interest at the Base Rate or the Eurodollar Rate, and, if appropriate, the Interest Period applicable thereto; (ii) the terms of each Assignment and Acceptance delivered to and accepted by it; (iii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each Lender Party; and (iv) the amount of any sums received by the Administrative Agent from the Borrower hereunder and each Lender Party’s share thereof.

 (c) Entries made in good faith by the Administrative Agent in the Register pursuant to subsection (b) above, and by each
Lender Party in its account or accounts pursuant to subsection (a) above, shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrower to, in the case of the
Register, each Lender Party and, in the case of such account or accounts, such Lender Party, under this Agreement, absent manifest error; provided, however, that the failure of the Administrative Agent or such Lender Party to make an
entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of the Borrower under this Agreement. 
 SECTION 2.15. Use of Proceeds. The proceeds of the Advances and issuances of any Letter of Credit shall be available (and the
Borrower agrees that it shall use proceeds of Advances made to it and each Letter of Credit issued at its request) solely for general corporate purposes. 
 SECTION 2.16. Request for Commitments. (a) Provided there exists no Default, upon notice to the Administrative Agent (which shall promptly notify the Lenders), the Borrower may, from time to
time, request an increase in the Facility by an amount (for all such requests) not exceeding $250,000,000; provided that (i) any such request for an increase shall be in a minimum amount of $50,000,000, and (ii) the Borrower may
make a maximum of three such requests. At the time of sending such notice, the Borrower (in consultation with the

  

					
		 	53	 	AESC Credit Agreement

 
Administrative Agent) shall specify the time period within which each Lender is requested to respond (which shall in no event be less than ten Business Days from the date of delivery of such
notice to the Lenders). Each Lender shall notify the Administrative Agent within such time period whether or not it agrees to increase its Commitment and, if so, whether in an amount equal to, greater than, or less than its Pro Rata Share of such
requested increase. Any Lender not responding within such time period shall be deemed to have declined to make any increase pursuant to this Section 2.16. The Administrative Agent shall notify the Borrower and each Lender of the Lenders’
responses to each request made hereunder. Subject to the approval of the Administrative Agent (which approval shall not be unreasonably withheld) and each Issuing Bank (in its sole discretion), the Borrower may invite additional Eligible Assignees
to become Lenders pursuant to a joinder agreement in form and substance satisfactory to the Administrative Agent and its counsel. 
 (b) If the Facility is increased in accordance with this Section 2.16, the Administrative Agent and the Borrower shall determine the effective date (the “Commitment Effective Date”) and the final allocation of
such increase. The Administrative Agent shall promptly notify the Borrower and the Lenders of the final allocation of such increase and the Commitment Effective Date. As a condition precedent to such increase, the Borrower shall deliver to the
Administrative Agent a certificate dated as of the Commitment Effective Date (in sufficient copies for each Lender) signed by a Responsible Officer of the Borrower (i) certifying and attaching the resolutions adopted by the Borrower approving
or consenting to such increase, and (ii) certifying that: (A) before and after giving effect to such increase, the representations and warranties of the Borrower contained in Article IV of this Agreement and the other Financing Documents
are true and correct on and as of the Commitment Effective Date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they are true and correct as of such earlier date, and except that
for purposes of this Section 2.16, the representations and warranties contained in Section 4.01(f) shall be deemed to refer to the most recent financial statements furnished pursuant to Section 5.04, (B) before and after giving
effect to such commitments, no Default exists, and (C) all Governmental Approvals necessary for the Borrower to so increase the Facility have been obtained, are in full force and effect. The Borrower shall prepay any Advances outstanding on the
Commitment Effective Date (and pay any additional amounts required pursuant to Section 8.04(d)) to the extent necessary to keep the outstanding Advances ratable with the revised Pro Rata Share arising from any nonratable increase in the
Commitment under this Section 2.16. 
 (c) This Section shall supersede any provisions in Section 2.09(h) and 8.01 to
the contrary.

Section 6.01(f), (1) the Commitments of each Lender Party and the obligation of each Lender Party to make Advances (other than a Advance by the Lenders pursuant to Section 2.03(b)) and of the Issuing Banks to make L/C Credit
Extensions shall automatically be terminated and (2) the Notes, all such interest and all such amounts shall automatically become and be due and payable, without presentment, demand, protest or any notice of any kind, all of which are hereby

demand the Borrower will, Cash Collateralize, for deposit in the Cash Collateral Account, an amount equal to the Outstanding Amount of all L/C Obligations. If at any time the Administrative Agent determines that any Cash Collateral is subject to any
right or claim of any Person other than the

  

					
		 	72	 	AESC Credit Agreement

 
Administrative Agent and the Lender Parties or that the Cash Collateral is less than the Outstanding Amount of all L/C Obligations, the Borrower will, forthwith upon demand by the Administrative
Agent, pay to the Administrative Agent additional Cash Collateral to be deposited and held in the Cash Collateral Account, in an amount equal to the excess of (a) such aggregate Outstanding Amount of all L/C Obligations over (b) the total
amount of Cash Collateral that the Administrative Agent determines to be free and clear of any such right and claim.

Law. The Administrative Agent agrees to give to each Lender Party prompt notice (including matters disclosed in writing to the Administrative Agent as described in clause (b) of the definition of “Disclosed Matters”) of each
notice given to it by the Borrower or any other Person pursuant to the terms of this Agreement or any other Financing Documents.

interest created or purported to be created under or in connection with, any Financing Document or any other instrument or document furnished pursuant thereto; and (f) the Administrative Agent shall incur no liability under or in respect of any

 SECTION 7.03. Bank of America, BAS, Scotia Capital, and Affiliates. With respect to its commitments, if any, to make loans pursuant
to its Commitment, the Advances made by it, the L/C Credit Extensions and the Notes issued to it, Bank of America, BAS and Scotia Capital shall have the same rights and powers under the Financing Documents as any other Lender and may exercise the

Party, and based on the financial statements referred to in Sections 3.01 and 5.04 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Financing
Documents to which it is a party. Each Lender Party also acknowledges that it will, independently and without reliance upon the Administrative Agent, any Arranger Party or any other Lender Party and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Financing Documents to which it is a party. 
 SECTION 7.05. Indemnification. (a) Each Lender severally agrees to indemnify the Administrative Agent (to the extent not
promptly reimbursed by the Borrower and without limiting its obligation to do so) from and against such Lender’s Pro Rata Share 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 in any way relating to or arising out of the Financing Documents or any action taken or omitted by the Administrative
Agent under the Financing Documents (collectively, the “Indemnified Costs”); provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting directly and primarily from the Administrative Agent’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without

reimburse the Administrative Agent promptly upon demand for its Pro Rata Share of any costs and expenses (including reasonable fees and expenses of counsel) payable by the Borrower under
Section 8.04, to the extent that the Administrative Agent is not promptly reimbursed for such costs and expenses by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this
Section 7.05 applies whether any such investigation, litigation or proceeding is brought by any Lender or any other Person. 
 (b) Each Lender severally agrees to indemnify each Issuing Bank (to the extent not promptly reimbursed by the Borrower and without limiting its obligation to do so) from and against such Lender’s Pro Rata Share 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 such Issuing Bank in its capacity as such in
any way relating to or arising out of the Financing Documents or any action taken or omitted by such Issuing Bank under the Financing Documents (including the issuance or transfer of, or payment or failure to pay under, any Letter of Credit);
provided that no Lender Party shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting directly and primarily from such Issuing
Bank’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse such Issuing Bank promptly upon demand for its

expenses by the Borrower.

Issuing Bank, as the case may be, promptly upon demand for its Pro Rata Share of any amount required to be paid by the Lender Parties to the Administrative Agent, any Arranger Party or any Issuing Bank, as the case may be, as provided herein shall
not relieve any other Lender Party of its obligation hereunder to reimburse the Administrative Agent, any Arranger Party or any Issuing Bank, as the case may be, for its Pro Rata Share of such amount, but no Lender Party shall be responsible for the
failure of any other Lender Party to reimburse the Administrative Agent, any Arranger Party or any Issuing Bank, as the case may be, for such other Lender Party’s Pro Rata Share of such amount. Without prejudice to the survival of any other
agreement of any Lender Party hereunder, the agreement and obligations of each Lender Party contained in this Section 7.05 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other
Financing Documents.

giving written notice thereof to the Lender Parties and the Borrower and may be removed at any time with or without cause by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor
Administrative Agent. 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
or the Required Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lender Parties, appoint a successor Administrative Agent, which shall be a commercial bank organized under the
laws of the United States or of any State thereof and having a combined

  

					
		 	75	 	AESC Credit Agreement

 
capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative 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 the Financing

expenses of its agents and of counsel, accountants and other experts), shall be paid in full by the Borrower promptly following demand from the Administrative Agent from time to time as services are rendered and expenses are incurred. All such
payments made by the Borrower to the Administrative Agent shall be made free and clear of all present and future income, stamp or other taxes, levies and withholdings imposed, assessed, levied or collected by the government of the United States of
America or any political subdivision or taxing authority thereof. Except as otherwise expressly provided herein, no Lender Party shall have any liability for any fees, expenses or disbursements of the Administrative Agent. Upon its resignation or
removal, the Administrative Agent shall be entitled to the prompt payment by the Borrower of its compensation and indemnification for the services rendered under this Agreement and the other Financing Documents to which it is a party and to
reimbursement of all reasonable out-of-pocket expenses up to the date of resignation or removal (including the reasonable fees and expenses of counsel, if any) incurred in connection with the performance of such services. The agreements in this
Section 7.08 shall survive any resignation or removal of the Administrative Agent and the termination of the other provisions of this Agreement. 
 SECTION 7.09. Exculpatory Provisions. The Administrative Agent makes no representation as to the title of the Borrower or as to the rights and interests granted or the security afforded by this
Agreement or any other Financing Document, or as to the validity, execution (except by itself), enforceability, legality or sufficiency of this Agreement, any other Financing Document, and the Administrative Agent (in its individual and agency
capacities) shall not incur any liability or responsibility in respect of any such matters.

Lender Party. 
 SECTION 7.11. Miscellaneous. (a) Instructions. The Administrative Agent shall have the right
at any time to seek instructions concerning the administration of its duties and obligations hereunder or under any other Financing Documents from the Lenders or any court of competent jurisdiction. In the event there is any disagreement between the
parties to this Agreement and the terms of this Agreement or any other applicable Financing Document do not unambiguously mandate the action the Administrative Agent is to take or not to take in connection therewith under the circumstances then
existing, or the Administrative Agent is in doubt as to what action it is required to take or not to take, the Administrative Agent (other than with respect to the Administrative Agent’s actions required under the final sentence of
Section 7.01(a)) shall be entitled to refrain from taking any action until directed otherwise in writing by a request signed jointly by the Required Lenders or by order of a court of competent jurisdiction. 
 (b) No Obligation. None of the provisions of this Agreement or the other Financing Documents shall be construed to require the
Administrative Agent to expend or risk its own funds or otherwise to incur any personal financial liability in the performance of any of its duties hereunder or thereunder. The Administrative Agent shall be under no obligation to exercise any of the
rights or powers vested in it by this Agreement or the other Financing Documents, at the request or direction of the Borrower or any Lender Party, (i) if any action it has been requested or directed to take would be contrary to Applicable Law,
or (ii) unless the Administrative Agent shall have been offered security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction (including
interest thereon from the time incurred until reimbursed).

Sections 7.03 and 8.12, none of the Lenders or other Persons identified on the cover page or signature pages of this Agreement as a “joint lead arranger”, “joint book runner” or “syndication agent”

the Lenders or other Persons so identified shall have or be deemed to have any fiduciary, agency or advisory relationship or other implied duty with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the
Lenders or other Persons so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

hereafter existing under the Financing Documents, irrespective of whether the Administrative Agent or such Lender Party shall have made any demand under this Agreement or such Note or Notes and although such Obligations may be unmatured. The
Administrative Agent and each Lender Party agrees promptly to notify the Borrower after any such set-off and application; provided, however, that the failure to give such notice shall not affect the validity of such set-off and
application. The rights of the Administrative Agent and each Lender Party and their respective Affiliates under this Section 8.05 are in addition to other rights and remedies (including other rights of set-off) that the Administrative Agent,
such Lender Party and their respective Affiliates may have. 
 SECTION 8.06. Binding Effect. This Agreement shall become
effective at such time as it shall have been executed by the Borrower and the Administrative Agent and the Administrative Agent shall have been notified by each Initial Lender Party that such Initial Lender Party has executed it and thereafter shall
be binding upon and inure to the benefit of the Borrower, the Administrative Agent and each Lender Party and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest
herein without the prior written consent of the Lender Parties. 
 SECTION 8.07. Assignments and Participations.
(a) Each Lender Party may and, if requested by the Borrower (following (i) a demand by such Lender Party for the payment of additional compensation pursuant to Section 2.12 or 2.13, (ii) an assertion by such Lender Party pursuant
to Section 2.10 that it is unlawful for such Lender Party to make Eurodollar Rate Advances or (iii) a failure by such Lender Party to approve any amendment or waiver pursuant to Section 8.01, provided that such amendment or
waiver would otherwise have been effective but

  

					
		 	82	 	AESC Credit Agreement

 
for such Lender Party’s failure, together with the failure of any other Lender Party to which the Borrower has made a similar request under this clause (a), to approve such amendment or
waiver, provided further that, with respect to clause (iii), such failure to approve shall have continued for a period of not less than five Business Days following written notice by the Borrower to such Lender Party of such request by the
Borrower), shall assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, the Advances owing to it, L/C Credit Extensions and the Note or Notes held
by it), including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided, however, that (i) each such assignment shall be of a uniform, and not a varying, percentage of all rights and obligations of
such Lender under and in respect of and shall be made on a pro rata basis with respect to each of the Advances held by such Lender, (ii) except in the case of an assignment to a Person that, immediately prior to such assignment, was a
Lender Party, an Affiliate of any Lender Party or an Approved Fund or an assignment of all of a Lender Party’s rights and obligations under this Agreement, the aggregate amount of any Commitment or Advance being assigned to such Eligible
Assignee pursuant to such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000 (or such lesser amount as shall be approved by the Administrative Agent) and
shall be in increments of $1,000,000 in excess thereof; provided that Related Funds shall be combined for purposes of determining compliance with such minimum assignment amounts, (iii) with respect to any Commitment, Advance, L/C Credit
Extension or L/C Borrowing, no such assignments (other than pledges or assignment by way of security to a Federal Reserve Bank) shall be permitted without the consent of each Issuing Bank (in each case, acting in its sole discretion), the
Administrative Agent (such consent not to be unreasonably withheld or delayed) and, so long as no Specified Default has occurred and is continuing, the consent of the Borrower (such consent not to be unreasonably withheld or delayed), except, with
respect to the Borrower’s consent only, assignments to any other Lender Party, an Affiliate of any Lender, any Approved Fund, and (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register, an Assignment and Acceptance, together with any Note or Notes subject to such assignment and a processing and recordation fee of $3,500 (such fee to be paid by the Borrower if such assignment is being made
pursuant to a request of the Borrower therefor under this Section 8.07(a)); provided that only one such fee shall be payable in the case of contemporaneous assignments to or by two or more Approved Funds and (v) each such assignment
thereof shall be made on a pro rata basis with respect to each of (A) such Lender’s Advances and L/C Credit Extensions and (B) such Lender’s Commitment; provided further that (I) each such assignment made as a
result of a request by the Borrower pursuant to this Section 8.07(a) shall be arranged by the Borrower with the approval of the Administrative Agent, which approval shall not be unreasonably withheld or delayed, and shall be either an
assignment of all of the rights and obligations of the assigning Lender under this Agreement or an assignment of a portion of such rights and obligations made concurrently with another such assignment or other such assignments that, in the
aggregate, cover all of the rights and obligations of the assigning Lender under this Agreement and (II) no Lender shall be obligated to make any such assignment as a result of a demand by the Borrower pursuant to this Section 8.07(a) unless
and until such Lender shall have received one or more payments from one or more Eligible Assignees in an aggregate amount at least equal to the aggregate outstanding principal amount of the Advances owing to such Lender, together with accrued
interest thereon to the date of payment of such principal amount, and from

  

					
		 	83	 	AESC Credit Agreement

 
the Borrower and/or one or more Eligible Assignees in an aggregate amount equal to all other amounts payable to such Lender under this Agreement and the other Financing Documents (including,
without limitation, any amounts owing under Section 2.12, 2.13 or 8.04). 
 (b) Any Issuing Bank may assign to an Eligible
Assignee all of its rights and obligations under the undrawn portion of its commitment hereunder to issue Letters of Credit at any time; provided, however, that (i) each such assignment shall be to an Eligible Assignee,
(ii) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with a processing and recordation fee of $3,500 and
(iii) so long as no Specified Default has occurred and is continuing, the Borrower has consented to the assignment (such consent not to be unreasonably withheld). 
 (c) Upon such execution, delivery, acceptance and recording, from and after the effective date specified in such Assignment and Acceptance, (i) the assignee thereunder shall be a party hereto and, to
the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender or Issuing Bank, as the case may be, hereunder and (ii) the Lender or Issuing Bank
assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (other than its rights under Sections 2.12, 2.13 and 8.04 to the extent any
claim thereunder relates to an event arising prior to such assignment) and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the remaining portion of an assigning Lender’s or
Issuing Bank’s rights and obligations under this Agreement, such Lender or Issuing Bank shall cease to be a party hereto). 
 (d) By executing and delivering an Assignment and Acceptance, each Lender Party assignor thereunder and each assignee thereunder confirm to and agree with each other and the other parties thereto and hereto as follows: (i) other than
as provided in such Assignment and Acceptance, such assigning Lender Party makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Financing
Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported to be created under or in connection with any Financing Document
or any other instrument or document furnished pursuant thereto; (ii) such assigning Lender Party makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or
observance by the Borrower of any of its obligations under any Financing Document or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of this Agreement and each other
Financing Document, together with copies of the financial statements referred to in Sections 4.01(f), 5.04(b) and 5.04(c) and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such assigning Lender Party or any other Lender Party 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 or any other Financing Document; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints
and authorizes each

  

					
		 	84	 	AESC Credit Agreement

 
Agent to take such action as agent on its behalf and to exercise such powers and discretion under the Financing Documents as are delegated to such Agent by the terms hereof and thereof, together
with such powers and discretion as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations that by the terms of this Agreement and the other Financing
Documents are required to be performed by it as a Lender or Issuing Bank, as the case may be. 
 (e) The Administrative Agent
shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lender Parties and the Commitments of, and
principal amount of the Advances and L/C Borrowings owing to, each Lender Party from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Administrative Agent and the Lender Parties shall treat each Person whose name is recorded in the Register as a Lender Party hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower
or the Administrative Agent or any Lender Party at any reasonable time and from time to time upon reasonable prior notice. 
 (f) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender Party and an assignee, together with any Note or Notes subject to such assignment, the Administrative Agent shall, if such Assignment and Acceptance has
been completed and is in substantially the form of Exhibit C, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. In the case
of any assignment by a Lender, within five Business Days after its receipt of such notice, the Borrower, at its own expense, shall execute and deliver to the Administrative Agent in exchange for the surrendered Note or Notes a new Note to the order
of such Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to such Assignment and Acceptance and, if any assigning Lender has retained a Commitment hereunder, a new Note to the order of such assigning Lender in an amount
equal to the Commitment retained by it hereunder. Such new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date of such Assignment and
Acceptance and shall otherwise be in substantially the form of Exhibit A. 
 (g) Each Lender Party may sell participations to
one or more Persons (other than the Borrower or any Affiliate of the Borrower) in or to all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, the Advances owing to it, L/C Credit
Extensions and the Note or Notes (if any) held by it); provided, however, that (i) any such sale shall be of a uniform and not varying percentage of all of its rights and obligations in respect of such Advances, (ii) such
Lender Party’s obligations under this Agreement (including its Commitment and L/C Credit Extensions) shall remain unchanged, (iii) such Lender Party shall remain solely responsible to the other parties hereto for the performance of such
obligations, (iv) such Lender Party shall remain the holder of any such Note for all purposes of this Agreement, (v) the Borrower, the Administrative Agent and the other Lender Parties shall continue to deal solely and directly with such
Lender Party in connection with such Lender Party’s rights and obligations under this Agreement and (vi) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of

  

					
		 	85	 	AESC Credit Agreement

 
any Financing Document, or any consent to any departure by the Borrower therefrom, except to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the
Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such participation, postpone any date fixed for any payment of principal of, or interest on, the Notes or any fees or other amounts payable hereunder, in
each case to the extent subject to such participation. 
 (h) Notwithstanding anything in this Agreement to the contrary
(including any other provision regarding assignments, participations, transfers or novations), any Lender (a “Granting Lender”) may, without the consent of any other party hereto, grant to a special purpose vehicle (whether a
corporation, partnership, limited liability company, trust or otherwise, an “SPV”) sponsored or managed by the Granting Lender or any Affiliate thereof, a participation in all or any part of any Advance (including the
Commitment therefor) that such Granting Lender has made or will make pursuant to this Agreement; provided that (i) such Granting Lender’s obligations under this Agreement (including its Commitment) shall remain unchanged;
(ii) such Granting Lender shall remain the holder of its Note for all purposes under this Agreement; and (iii) the Borrower, the Administrative Agent and the other Lenders shall continue to deal solely and directly with such Granting
Lender in connection with such Granting Lender’s rights and obligations under the Financing Documents. Each party hereto hereby agrees that (A) no SPV will be entitled to any rights or benefits that a Lender would not otherwise be entitled
to under this Agreement or any other Financing Document; and (B) an SPV may assign its interest in any Advance under this Agreement to any Person that would constitute a Lender subject to the satisfaction of all requirements for an assignment
by any Lender set forth in this Section 8.07. Notwithstanding anything in this Agreement to the contrary, the Granting Lender and any SPV may, without the consent of any other party to this Agreement, and without limiting any other rights of
disclosure of the Granting Lender under this Agreement, disclose on a confidential basis any non-public information relating to its funding of its Advances to (1) (in the case of the Granting Lender) any actual or prospective SPV, (2) (in
the case of an SPV) its lenders, sureties, reinsurers, guarantors or credit liquidity enhancers, (3) their respective directors, officers, and advisors, and (4) any rating agency. 
 (i) Any Lender Party may, in connection with any assignment or participation or proposed assignment or participation pursuant to this
Section 8.07, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrower furnished to such Lender Party by or on behalf of the Borrower, subject to the requirements set forth in
Section 8.12. 
 (j) Notwithstanding any other provision set forth in this Agreement, any Lender Party may at any time
pledge or assign a security interest in all or any portion of its rights under this Agreement (including the Advances owing to it and the Note or Notes held by it) to secure the obligations of such Lender Party, including any pledge or assignment to
secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender Party from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender Party as a party hereto.

 SECTION 8.08. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different
parties hereto in separate counterparts, each of

  

					
		 	86	 	AESC Credit Agreement

 
which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to
this Agreement by telecopier shall be effective as delivery of an original executed counterpart of this Agreement. 
 SECTION
8.09. Jurisdiction, Etc. (a) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property, to the non-exclusive jurisdiction of any New York State court or Federal court of the United States of
America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any of the other Financing Documents to which it is a party, or for recognition or enforcement of
any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the fullest extent permitted
by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or any of the other Financing Documents in the courts of any jurisdiction. 
 (b) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any of the other Financing Documents to which it is a party in any New York State or Federal court.
Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
 SECTION 8.10. Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the
State of New York. 
 SECTION 8.11. Waiver of Jury Trial. The Borrower, the Administrative Agent and the Lender Parties
irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to any of the Financing Documents, the Advances, any Letter of Credit or the actions of
the Administrative Agent or any Lender Party in the negotiation, administration, performance or enforcement thereof. 
 SECTION
8.12. Confidentiality. (a) Neither the Administrative Agent, any Arranger Party nor any Lender Party may, without the prior written consent of the Borrower, disclose to any Person (i) any confidential, proprietary or non-public
information of the Borrower furnished to the Administrative Agent, the Arranger Parties or the Lender Parties by the Borrower (such information being referred to collectively herein as the “Confidential Information”) or
(ii) the fact that the Confidential Information has been made available or any of the terms, conditions or other facts with respect to the Confidential Information, in each case except as permitted by Section 8.07 or this Section 8.12
and except that the Administrative Agent, each of the Arranger Parties and each of the Lender Parties may disclose Confidential Information (i) to its and its Affiliates’ employees, officers, directors, agents sub-agents, and

  

					
		 	87	 	AESC Credit Agreement

 
advisors (collectively, “Representatives”) who need to know the Confidential Information for the purpose of administering or enforcing its rights under this Agreement and
the other Financing Documents and the transactions contemplated hereby and thereby or for the discharge of their duties (it being understood that the Representatives to whom such disclosure is made will be informed of the confidential nature of such
Confidential Information and instructed to keep such Confidential Information confidential on substantially the same terms as provided herein), (ii) to the extent requested by any regulatory authority having jurisdiction over it or to the
extent necessary for purposes of enforcing this Agreement or any other Financing Document, (iii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iv) to any other party to this
Agreement, (v) in connection with the exercise of any remedies hereunder or under any other Financing Document or any suit, action or proceeding relating to this Agreement or any other Financing Document or the enforcement of rights hereunder
or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section 8.12, to any assignee or pledgee of or participant in, or any prospective assignee or pledgee of or participant in, any of
its rights or obligations under this Agreement, including in the case of any securitization or collateralization of, or other similar transaction relating to the rights and obligations of any Lender or Lenders hereunder, disclosure to any necessary
Person in connection with such securitization, collateralization or other transaction (including any funding vehicle organized to undertake or effectuate such securitization, collateralization or other transaction, its lenders, sureties, reinsurers,
swap counterparties, guarantors or credit liquidity enhancers, their respective directors, officers, and advisors, and any rating agency or to any credit insurance provider relating to the Borrower and its Obligations), so long as the Persons to
whom such disclosure is made will be informed of the confidential nature of such Confidential Information and such Persons have agreed in writing (or with respect to any rating agency, in writing or otherwise) to keep such Confidential Information
confidential on substantially the same terms as provided herein, (vii) to the extent such Confidential Information (A) is or becomes generally available to the public on a non-confidential basis other than as a result of a breach of this
Section 8.12 by the Administrative Agent, such Arranger Party or such Lender Party, or (B) is or becomes available to the Administrative Agent, such Arranger Party or such Lender Party on a nonconfidential basis from a source other than a
Borrower and (viii) with the consent of the Borrower. 
 (b) Neither the Administrative Agent, any Arranger Party nor any
Lender Party shall, without the prior written consent of the Borrower, use, either directly or indirectly, any of the Confidential Information except in connection with this Agreement and the other Financing Documents and the transactions
contemplated hereby and thereby. 
 (c) Notwithstanding the foregoing, any of the parties hereto may disclose to any and all
Persons, without limitation of any kind, the U.S. tax treatment and U.S. tax structure of the transactions contemplated by this Agreement and the other Financing Documents and all materials of any kind (including opinions or other tax analyses) that
are provided to such parties relating to such U.S. tax treatment and U.S. tax structure. 
 (d) In the event that the
Administrative Agent, any Arranger Party or any Lender Party becomes legally compelled to disclose any of the Confidential Information otherwise than as contemplated by Section 8.12(a), the Administrative Agent, such Arranger Party or such
Lender Party shall provide the Borrower with notice of such event promptly upon its obtaining

  

					
		 	88	 	AESC Credit Agreement

 
knowledge thereof (provided that it is not otherwise prohibited by Applicable Law from giving such notice) so that the Borrower may seek a protective order or other appropriate remedy. In
the event that such protective order or other remedy is not obtained, the Administrative Agent, such Arranger Party or such Lender Party shall furnish only that portion of the Confidential Information that it is legally required to furnish and shall
cooperate with the Borrower’s counsel to enable the Borrower to obtain a protective order or other reliable assurance that confidential treatment will be accorded the Confidential Information. 
 (e) In the event of any breach of this Section 8.12, the Borrower shall be entitled to equitable relief (including injunction and
specific performance) in addition to all other remedies available to it at law or in equity. 
 (f) Neither the Administrative
Agent, any Arranger Party nor any Lender Party shall make any public announcement, advertisement, statement or communication regarding the Borrower, its Affiliates (insofar as such announcement, advertisement, statement or communication relates to
the Borrower or the transactions contemplated hereby) or this Agreement or the transactions contemplated hereby without the prior consent of the Borrower (such consent not to be unreasonably withheld or delayed). 
 (g) The obligations of the Administrative Agent, each Arranger Party and each Lender under this Section 8.12 shall survive for a period
of one year following the termination or expiration of this Agreement. 
 SECTION 8.13. Benefits of Agreement. Nothing in
this Agreement or any other Financing Document, express or implied, shall give to any Person, other than the parties hereto, each Indemnified Party and each of their successors and permitted assigns under this Agreement or any other Financing
Document, any benefit or any legal or equitable right or remedy under this Agreement; provided that each Indemnified Party and its successors and assigns shall not have any benefit or any legal or equitable right or remedy under this
Agreement other than as provided by Section 8.04(b). 
 SECTION 8.14. Severability. If any provision of this
Agreement shall be invalid, illegal or unenforceable, then to the extent permitted by law, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 SECTION 8.15. Limitations. (a) The obligations, liabilities or responsibilities of any party hereunder shall be limited to those
obligations, liabilities or responsibilities expressly set forth and attributed to such party pursuant to this Agreement or otherwise applicable under Applicable Law. 
 (b) In no event shall any Indemnified Party be liable for, and the Borrower hereby agrees not to assert any claim against any Indemnified Party, on any theory of liability, for, consequential, incidental,
indirect, punitive or special damages arising out of or otherwise relating to the Notes, this Agreement, the other Financing Documents, any of the transactions contemplated herein or therein or the actual or proposed use of the proceeds of the
Advances or L/C Credit Extensions. 
  

					
		 	89	 	AESC Credit Agreement

 SECTION 8.16. Survival. Notwithstanding anything in this Agreement to the contrary,
Sections 7.05, 7.08, 7.12, 8.04, 8.09, 8.10, 8.11, 8.12 8.15 and 8.16 shall survive any termination of this Agreement. In addition, each representation and warranty made or deemed to be made hereunder shall survive the making of such representation
and warranty, and no Lender Party shall be deemed to have waived, by reason of making any Advance or making any payment pursuant thereto, any Default that may arise by reason of such representation or warranty proving to have been false or
misleading, notwithstanding that such Lender Party may have had notice or knowledge or reason to believe that such representation or warranty was false or misleading at the time such Advance or L/C Credit Extension was made. 
 SECTION 8.17. USA Patriot Act Notice. Each of the Lender Parties and the Administrative Agent (for itself and not on behalf of any
Lender Party) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and
record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender Party or the Administrative Agent, as applicable, to identify the Borrower in
accordance with the Act. 
 SECTION 8.18. No Fiduciary Duty. Each Agent, each Lender and their Affiliates (collectively,
solely for purposes of this paragraph, the “Lenders”), may have economic interests that conflict with those of the Borrower, its stockholders and/or its affiliates. The parties hereto acknowledge and agree that (i) the
transactions contemplated by the credit documents (including the exercise of rights and remedies hereunder and thereunder) are arm’s-length commercial transactions between the Lenders, on the one hand, and the Borrower, on the other, and
(ii) in connection therewith and with the process leading thereto, (x) no Lender has assumed an advisory or fiduciary responsibility in favor of the Borrower, its stockholders or its affiliates with respect to the transactions contemplated
hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of whether any Lender has advised, is currently advising or will advise the Borrower, its stockholders or its Affiliates on other
matters) or any other obligation to the Borrower except the obligations expressly set forth in the credit documents and (y) each Lender is acting solely as principal and not as the agent or fiduciary of the Borrower, its management,
stockholders, creditors or any other Person. The Borrower acknowledges and agrees that the Borrower has consulted its own legal and financial advisors to the extent it deemed appropriate and that it is responsible for making its own independent
judgment with respect to such transactions and the process leading thereto.

	$                        	  	Dated:                          ,
        

 FOR VALUE RECEIVED, the undersigned, ALLEGHENY ENERGY SUPPLY COMPANY, LLC, a Delaware
limited liability company (the “Borrower”), HEREBY PROMISES TO PAY
                                         (the
“Lender”) for the account of its Applicable Lending Office (as defined in the Credit Agreement referred to below) the aggregate principal amount of the Advances (as defined in the Credit Agreement referred to below) owing to
the Lender by the Borrower pursuant to the Credit Agreement dated as of September 24, 2009, (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; terms defined
therein, unless otherwise defined herein, being used herein as therein defined) among the Borrower, the financial institutions referred to therein as Lenders, the Initial Issuing Banks and Bank of America, N.A., as Administrative Agent, on the Final
Maturity Date and at such other times specified therein. 
 The Borrower promises to pay interest on the unpaid principal amount
of each Advance from the date of such Advance until such principal amount is paid in full, at such interest rates, and payable at such times, as are specified in the Credit Agreement. 
 Both principal and interest are payable in lawful money of the United States of America to Bank of America, N.A., as Administrative Agent, at Bank of America, N.A., 901 Main Street, Mail Code:
TX1-492-14-04, Dallas, TX 75202-3714, Attention: Betty L. Coleman in immediately available funds. Each Advance owing to the Lender by the Borrower, and all payments made on account of principal thereof, shall be recorded by the Lender and,
prior to any transfer hereof, endorsed on the grid attached hereto, which is part of this Note; provided, however, that the failure of the Lender to make any such recordation or endorsement shall not affect the Obligations of the Borrower
under this Note. 
 This Note is one of the Notes referred to in, and is entitled to the benefits of, the Credit Agreement. The
Credit Agreement, among other things, (i) provides for the making of Advances by the Lender to the Borrower in an aggregate amount not to exceed at any time outstanding the Dollar amount first above mentioned, the indebtedness of the Borrower
resulting from each such Advance being evidenced by this Note, and (ii) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events and also for repayments and prepayments on account of principal
hereof prior to the maturity hereof upon the terms and conditions therein specified.

 AESC CREDIT AGREEMENT 
 FORM OF ASSIGNMENT AND ACCEPTANCE 
 Reference is made to the Credit Agreement, dated as of September 24, 2009, (as amended, amended and restated, supplemented or otherwise
modified from time to time, the “Credit Agreement”; the terms defined therein, unless otherwise defined herein, being used herein as therein defined) among ALLEGHENY ENERGY SUPPLY COMPANY, LLC, a Delaware limited liability
company (the “Borrower”), the financial institutions referred to therein as Lenders and Initial Issuing Banks, and Bank of America, N.A., as Administrative Agent. 
 [                    ]
(the “Assignor”) and [                    ] (the “Assignee”) each agrees severally with
respect to all information relating to it and its assignment hereunder and on Schedule 1 hereto as follows: 
 The Assignor
hereby sells and assigns, without recourse except as to the representations and warranties made by it herein, to the Assignee, and the Assignee hereby purchases and assumes from the Assignor, an interest in and to the Assignor’s rights and
obligations under the Credit Agreement as of the date hereof equal to the percentage interest specified on Schedule 1 hereto of all outstanding rights and obligations under the Credit Agreement [and, if the Assignor is an Issuing Bank, all of the
Assignor’s rights and obligations under the Credit Agreement as an Issuing Bank]. After giving effect to such sale and assignment, the Assignee’s Commitment and the amount of Advances owing to the Assignee will be as set forth on
Schedule 1 hereto. 
 The Assignor (i) represents and warrants that it is the legal and beneficial owner of the
interest or interests being assigned by it hereunder and that such interest or interests are free and clear of any adverse claim; (ii) makes no representation or warranty and assumes no responsibility with respect to any statements, warranties
or representations made in or in connection with any Financing Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the perfection or priority of any lien or security interest created or purported
to be created under or in connection with, any Financing Document or any other instrument or document furnished pursuant thereto; (iii) makes no representation or warranty and assumes no responsibility with respect to the financial condition of
the Borrower or the performance or observance by the Borrower of any of its obligations under any Financing Document or any other instrument or document furnished pursuant thereto; and (iv) attaches the Note (if any) held by the Assignor and
requests that the Administrative Agent exchange such Note (if any) for a new Note payable to the order of the Assignee in an amount equal to the Commitment assumed by the Assignee pursuant hereto or new Notes payable to the order of the Assignee in
an amount equal to the Commitment assumed by the Assignee pursuant hereto and the Assignor in an amount equal to the Commitment retained by the Assignor under the Credit Agreement, respectively, as specified on Schedule 1 hereto. 
 The Assignee (i) confirms that it has received a copy of the Credit Agreement and each of the other Financing Documents, together with
copies of the financial statements referred to in Sections 3.01 and 5.04 of the Credit Agreement and such other documents and information

 
as it has deemed appropriate to make its own credit analysis and decision to enter into this Assignment and Acceptance; (ii) agrees that it will, independently and without reliance upon the
Administrative Agent, the Assignor or any other Lender or Arranger Party 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 the Credit
Agreement or any other Financing Document; (iii) confirms that it is an Eligible Assignee; (iv) appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under
the Financing Documents as are delegated to the Administrative Agent, respectively, by the terms thereof, together with such powers and discretion as are reasonably incidental thereto; (v) agrees that it will perform in accordance with their
terms all of the obligations that by the terms of the Financing Documents are required to be performed by it as a Lender; and (vii) attaches any U.S. Internal Revenue Service forms required under Section 2.13 of the Credit Agreement.

 Following the execution of this Assignment and Acceptance, it will be delivered to the Administrative Agent for acceptance
and recording by the Administrative Agent. The effective date for this Assignment and Acceptance (the “Effective Date”) shall be the date of acceptance hereof by the Administrative Agent, unless otherwise specified on
Schedule 1 hereto. 
 Upon such acceptance and recording by the Administrative Agent, as of the Effective Date,
(i) the Assignee shall be a party to the Credit Agreement and, to the extent provided in this Assignment and Acceptance, have the rights and obligations of a Lender thereunder and (ii) the Assignor shall, to the extent provided in this
Assignment and Acceptance, relinquish its rights and be released from its obligations under the Financing Documents (other than its rights and obligations under the Financing Documents that are specified under the terms of such Financing Documents
to survive the payment in full of the Obligations of the Borrower under the Financing Documents to the extent any claim thereunder relates to an event arising prior to the Effective Date of this Assignment and Acceptance) and, if this Assignment and
Acceptance covers all of the remaining portion of the rights and obligations of the Assignor under the Credit Agreement, the Assignor shall cease to be a party thereto. 
 Upon such acceptance and recording by the Administrative Agent, from and after the Effective Date, the Administrative Agent shall make all payments under the Credit Agreement and the Notes (if any) in
respect of the interest assigned hereby (including all payments of principal, interest and commitment fees with respect thereto) to the Assignee. The Assignor and the Assignee shall make all appropriate adjustments in payments under the Credit
Agreement and the Notes (if any) for periods prior to the Effective Date directly between themselves. 
 This Assignment and
Acceptance shall be governed by, and construed in accordance with, the laws of the State of New York. 
 This Assignment
and Acceptance may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of Schedule 1 to this Assignment and Acceptance by telecopier shall be effective as delivery of an original executed counterpart of this Assignment and Acceptance.
