Borrower may borrow under this Section 2.01(a), prepay pursuant to Section 2.06(a) and reborrow under this Section 2.01(a).

 (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 Revolving Lender’s
obligations to fund under Section 2.03 exists, unless such Issuing Bank has entered into satisfactory arrangements with the Borrower or such Revolving Lender to eliminate such Issuing Bank’s risk with respect to such Revolving 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 2.02(c) or 2.03, each Borrowing shall be made on notice, given by the Borrower not later than 12:00 noon (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 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 Appropriate 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, 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 under the applicable Facility and the other
Appropriate 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 (x) with respect to the Initial Borrowing, directly
apply (1) the Revolving Advances (or such portion thereof as may

  

					
		  	43	  	AESC Credit Agreement

 
be specified in writing to the Administrative Agent by the Borrower) to the repayment of the Existing Debt, and (2) the Term Advances to the repayment of the Existing Debt and (y) with
respect to subsequent Revolving Borrowings, make such funds available to the Borrower, by crediting the Borrowing Account; provided, however, that, in the case of any subsequent Revolving Borrowing, the Administrative Agent shall first make a
portion of such funds equal to the aggregate principal amount of any Swing Line Advances and L/C Borrowing made by the Swing Line Bank or any Issuing Bank and by any other Revolving Lender, as the case may be, and outstanding on the date of such
Revolving Borrowing, plus interest accrued and unpaid thereon to and as of such date, available to the Swing Line Bank or such Issuing Bank or such other Revolving Lender, as the case may be, for repayment of such Swing Line Advances and 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 Swing Line Borrowing
shall be made on notice, given not later than 3:00 p.m. (New York City time) on the date of the proposed Swing Line Borrowing, by the Borrower to the Swing Line Bank and the Administrative Agent. Each such notice of a Swing Line Borrowing
(a “Notice of Swing Line Borrowing”) shall be by telephone, confirmed immediately in writing, or telecopier or electronic mail, specifying therein the requested (i) date of such Borrowing, (ii) amount of such
Borrowing and (iii) maturity of such Borrowing (which maturity shall be no later than the seventh day after the requested date of such Borrowing). The Swing Line Bank will make the amount thereof available to the Administrative Agent at the
Administrative Agent’s Account, in same day funds. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds
available to the Borrower by crediting the Borrowing Account. Upon written demand by the Swing Line Bank, with a copy of such demand to the Administrative Agent, each other Revolving Lender shall purchase from the Swing Line Bank, and the Swing Line
Bank shall sell and assign to each such other Revolving Lender, such other Revolving Lender’s Pro Rata Share of such outstanding Swing Line Advance as of the date of such demand, by making available for the account of its Applicable Lending
Office to the Administrative Agent for the account of the Swing Line Bank, by deposit to the Administrative Agent’s Account, in same day funds, an amount equal to the portion of the outstanding principal amount of such Swing Line Advance to be
purchased by such Revolving Lender. The Borrower hereby agrees to each such sale and assignment. Each Revolving Lender agrees to purchase its Pro Rata Share of an outstanding Swing Line Advance on (i) the Business Day on which demand therefor
is made by the Swing Line Bank; provided that notice of such demand is given not later than 12:00 noon (New York City time) on such Business Day or (ii) the first Business Day next succeeding such demand if notice of such
demand is given after such time. Upon any such assignment by the Swing Line Bank to any other Revolving Lender of a portion of a Swing Line Advance, the Swing Line Bank represents and warrants to such other Lender that the Swing Line Bank is the
legal and beneficial owner of such interest being

  

					
		  	44	  	AESC Credit Agreement

 
assigned by it, but makes no other representation or warranty and assumes no responsibility with respect to such Swing Line Advance, the Financing Documents or the Borrower. If and to the extent
that any Revolving Lender shall not have so made the amount of such Swing Line Advance available to the Administrative Agent, such Revolving Lender agrees to pay to the Administrative Agent forthwith on demand such amount together with interest
thereon, for each day from the date of demand by the Swing Line Bank until the date such amount is paid to the Administrative Agent, at the Federal Funds Rate. If such Revolving Lender shall pay to the Administrative Agent such amount for the
account of the Swing Line Bank on any Business Day, such amount so paid in respect of principal shall constitute a Swing Line Advance made by such Revolving Lender on such Business Day for purposes of this Agreement, and the outstanding principal
amount of the Swing Line Advance made by the Swing Line Bank shall be reduced by such amount on such Business Day. 
 (d) Each
Notice of Borrowing and Notice of Swing Line 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 Appropriate 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 (including 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. 
 (e)
Subject to the Administrative Agent giving prompt notice of the relevant Notice of Borrowing received by the Administrative Agent to the Term Lenders or the Revolving Lenders, as the case may be, unless the Administrative Agent shall have received
notice from an Appropriate 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 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. 
  

					
		  	45	  	AESC Credit Agreement

 (f) 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 12:00 noon (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 Revolving Lenders in accordance with
Section 2.01(e)(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 Revolving 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 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 Revolving Lender shall be

  

					
		  	46	  	AESC Credit Agreement

 
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
Revolving 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 Revolving
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 Revolving Lenders in accordance with Section 2.01(e)(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(d), 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 Revolving Lenders have elected not to permit such extension or (2) from the
Administrative Agent or any Revolving 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 Revolving Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”), and the amount of such Revolving Lender’s Pro Rata
Share thereof. In such event, the Borrower shall be deemed to have requested a Revolving Borrowing of Base Rate Advances to be disbursed on the Honor

  

					
		  	47	  	AESC Credit Agreement

 
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 Revolving Lender (including the Revolving 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 Revolving 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 Revolving 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 Revolving 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 Revolving Lender in satisfaction of its
participation obligation under this Section 2.03. 
 (iv) Until each Revolving Lender funds its Revolving 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 Revolving Lender’s Pro Rata Share of such drawing shall be solely for the account of such
Issuing Bank. 
 (v) Each Revolving Lender’s obligation to make Revolving 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 absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or
other right which such Revolving 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. 
  

					
		  	48	  	AESC Credit Agreement

 (vi) If any Revolving Lender fails to make available to the Administrative Agent for the
account of any Issuing Bank any amount required to be paid by such Revolving 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 Revolving 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 Revolving 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 Revolving Lender such Revolving 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 Revolving Lender its Pro Rata Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Revolving 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 Revolving 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 Revolving Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect. 
 (d) Role of Issuing Bank. Each Revolving 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 Revolving Lender for (i) any action taken or omitted in connection
herewith at the request or with the approval of the Revolving Lenders or the Required Revolving 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

  

					
		  	49	  	AESC Credit Agreement

 
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 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. Upon the occurrence and during the continuance of any Event of Default, at the request of the Administrative
Agent, (i) 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 (ii) 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 Revolving Lenders in accordance with Section 2.01(e)(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 Revolving Lenders in accordance with Section 2.01(e)(i)), as the case may be). The Borrower hereby grants to the Administrative Agent, for the benefit of each Issuing Bank and the
Revolving 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. 
 (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. 
  

					
		  	50	  	AESC Credit Agreement

 (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 Revolving 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 
  

					
		  	51	  	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. Without prejudice to the foregoing, the Borrower shall repay to the Administrative Agent for the account of the Swing Line Bank and
each other Revolving Lender that has made a Swing Line Advance the outstanding principal amount of each Swing Line Advance made by each of them on the earlier of the maturity date specified in the applicable Notice of Swing Line Borrowing (which
maturity shall be no later than the seventh day after the requested date of such Borrowing) and the Final Maturity Date. 
  

					
		  	52	  	AESC Credit Agreement

 SECTION 2.05. Termination or Reduction of the Commitments. (a) Optional. The
Borrower may, upon at least three Business Days’ notice to the Administrative Agent, terminate in whole or reduce in part the unused portion of the Revolving Commitments and the Term Commitments; provided that (i) each partial
reduction of a Facility shall be in an aggregate amount of $2,000,000 or an integral multiple of $1,000,000 in excess thereof and (ii) each partial reduction of a Facility shall be made ratably among the Appropriate Lenders in accordance with

Event Proceeds in respect of any Recovery Event or any series of related Recovery Events will be in excess of $25,000,000, the Borrower may elect to restore or replace the Asset (or portion thereof) affected by such Recovery Event if the Borrower
has delivered to the Administrative Agent, within 180 days from the occurrence of such Recovery Event, each of the following: (1) (x) a detailed breakdown of the nature and extent of such Recovery Event and (y) a bona fide assessment
of the estimated cost and time needed to restore or replace the Asset (or relevant portion thereof) in order for such Asset (or relevant portion thereof) to operate at substantially the same level as prior to the Recovery Event;
(2) satisfactory evidence that such Recovery Event Proceeds, together with any cash proceeds that have been or are expected to be paid to the Borrower or the Material Subsidiaries in respect of such Recovery Event, and any other cash expected
to be made available by or on behalf of the Borrower or the Material Subsidiaries with respect to whose Asset the Recovery Event occurred, are or are expected to be sufficient to make the necessary restorations or replacements to such Asset (or
relevant portion thereof); and (3) an Officer’s Certificate of the Borrower certifying that (x) the Asset (other than any Excluded Asset) subject to restoration/replacement will, if such restoration/replacement is to occur prior to
the Collateral Release Date, be subject to the Liens of the Collateral Documents (whether by amendment to the Collateral Documents or otherwise); (y) all material Governmental Approvals necessary to perform the work necessary to restore or
replace the Asset (or relevant portion thereof) affected by the relevant Recovery Event (or series of related Recovery Events) have been obtained (or are reasonably expected to be obtained without undue delay or as needed); and (z) the Asset
(or relevant portion thereof) once repaired/restored will be of similar value and general utility as immediately prior to the loss; provided that, if the Borrower does not deliver the information and Officer’s Certificate set forth in
this clause (B) within such 180-day period, the Borrower shall, as soon as reasonably practicable after such 180-day period, prepay the Advances in an aggregate principal amount equal to such Recovery Event Proceeds in accordance with clause
(A) above; and 
 (C) Upon completion of the restoration and replacement in respect of any Asset (or the
relevant portion thereof) with respect to which the Borrower delivered the information and Officer’s Certificate set forth in clause (B)(3) above, if (1) either (x) such restoration and replacement is completed before the Collateral
Release Date or (y) the Borrower did not diligently pursue such restoration and replacement and such

  

					
		  	54	  	AESC Credit Agreement

 
restoration and replacement is completed after the Collateral Release Date, and (2) the Recovery Event Proceeds in respect of the relevant Recovery Event (or series of related Recovery
Events) exceed the cost of such restoration and replacement by more than $1,000,000, in an aggregate principal amount equal to such amount over $1,000,000; it being understood that the Borrower shall not be required to use any Recovery Event
Proceeds in respect of a Recovery Event or series of related Recovery Events, which it believes, based on reasonable estimates of loss, will be $25,000,000 or less in the aggregate, to pay or as reimbursement for the costs of the necessary repairs
to or replacement of Assets affected by the relevant Recovery Event pursuant to clause (B) above and this clause (C). 
 (iii) Prepayments pursuant to this Section 2.06(b) shall be applied, first, to repay Term Advances outstanding at such time until all such Term Advances are paid in full or, if the Net Cash
Proceeds arising from such sale, transfer or other disposition of Assets occurs prior to the Initial Borrowing, to permanently reduce the Term Commitments, second, to repay Swing Line Advances and L/C Borrowings outstanding at such time,
pro rata, until all such Swing Line Advances and L/C Borrowings are paid in full, third, to repay Revolving Advances outstanding at such time until all such Revolving Advances are paid in full, and fourth, to Cash Collateralize
the L/C Obligations (the sum of such prepayment amounts, cancellation of Term Commitments and Cash Collateralization amounts being the “Reduction Amount”).

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

Period and Interest Rate. Promptly after receipt of a Notice of Borrowing pursuant to Section 2.02(a), a Notice of Conversion/Continuation pursuant to 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 Appropriate 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 Revolving Lenders a commitment fee from the date hereof in the case of each Initial Lender holding a Revolving Commitment and from the effective date
specified in the Assignment and Acceptance pursuant to which it became a Revolving Lender in the case of each other Revolving 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 sum of (i) the average daily Unused Commitment of such Revolving Lender during such fiscal quarter plus (ii) its Pro

 (b)
Letter of Credit Fees. The Borrower shall pay to the Administrative Agent for the account of each Revolving 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. Notwithstanding anything to the contrary contained herein, upon the request of the Required Revolving Lenders, while any
payment-related Default exists, all Letter of Credit Fees shall accrue at the Applicable Margin for Eurodollar Rate Advances plus 2%. 
  

					
		  	56	  	AESC Credit Agreement

 (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 equal to 0.10% 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) Agents’ Fees. The
Borrower shall pay to each Agent for its own account such fees as may from time to time be agreed between the Borrower and such 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 12:00 noon (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 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. 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 any Agent (whether for its own account or for the account of any
Lender Party shall be made to such Agent. 
  

					
		  	57	  	AESC Credit Agreement

 (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 (other than any Pledged Account or the Controlled 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 next 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 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. 
  

					
		  	58	  	AESC Credit Agreement

 (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 or 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, (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 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

  

					
		  	59	  	AESC Credit Agreement

 
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 (other than a
Swing Line 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 (other than a Swing Line Borrowing), in which case each such portion shall be allocated ratably among the Appropriate 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 1:00 p.m. (New York City time) on the requested date of a Conversion into Base Rate Advances and (ii) by 12:00 noon (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 among the Appropriate 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. 
  

					
		  	60	  	AESC Credit Agreement

 (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 Appropriate 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 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

  

					
		  	61	  	AESC Credit Agreement

 
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. 
 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

  

					
		  	62	  	AESC Credit Agreement

 
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. 
 (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

  

					
		  	63	  	AESC Credit Agreement

 
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 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

  

					
		  	64	  	AESC Credit Agreement

 
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. 
 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

  

					
		  	65	  	AESC Credit Agreement

 
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-1 or Exhibit A-2 hereto, as applicable, 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 (a) in the case of the Term Borrowing and, to the extent proceeds of such Revolving Borrowing are not applied in accordance with clause (b) below, each Revolving Borrowing on the Closing
Date, to repay in full the Existing Debt, (b) in the case of each subsequent Revolving Borrowing (and each Revolving Borrowing comprising the Initial Borrowing that is not required to pay the Existing Debt) and Letter of Credit, for working
capital for the Borrower and its Subsidiaries and (c) in the case of any additional borrowing made pursuant to Section 2.16, 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 from the Lenders commitments to make new loans (to

  

					
		  	66	  	AESC Credit Agreement

 
be Advances for all purposes under this Agreement and the other Financing Documents) in an aggregate amount (for all such requests) not exceeding $200,000,000 (the “Incremental
Commitments”); provided that (i) any such request for a commitment shall be in a minimum amount of $50,000,000, (ii) the Borrower may make a maximum of three such requests and (iii) the advances made pursuant to
this Section 2.16 in connection with such request shall initially be Base Rate Advances. At the time of sending such notice, the Borrower (in consultation with the 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 provide any
such commitment and, if so, whether in an amount equal to, greater than, or less than its ratable share of such requested commitment. Any Lender not responding within such time period shall be deemed to have declined to make any commitment 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. To achieve the full amount of a requested commitment, the Borrower may also 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 any Incremental Commitments are made 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 commitments. The Administrative Agent shall promptly notify the Borrower and the Lenders of the final allocation of such commitments and the Commitment Effective Date. As a condition precedent to
such commitments, 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 commitments, and (ii) certifying that: (A) before and after giving effect to such commitments, 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(g) 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, (C) the Borrower is in pro forma compliance with the covenants set forth in Section 5.03 for the period of four consecutive fiscal
quarters ending on the last date of the last fiscal quarter for which financial statements are available immediately preceding the proposed date of incurrence of Debt pursuant to this Section 2.16(b) (on the assumption that such incurrence of
Debt under this provision occurred on the first day of such four fiscal quarter period and using historical results of the Borrower and its Subsidiary for such period), (D) all Governmental Approvals necessary for the Borrower to incur the Debt
to be incurred under this Section 2.16 have been obtained, are in full force and effect and (E) with respect to any Debt to be incurred under this Section 2.16 prior to the Collateral Release Date, the Borrower has complied with the
Real Property Requirements. 
  

					
		  	67	  	AESC Credit Agreement

 (c) On each Commitment Effective Date, upon fulfillment of the conditions set forth in
clause (b) above, the Administrative Agent shall notify the Lenders and the Borrower, on or before 12:00 p.m. (New York City time) on the Business Day immediately preceding the proposed Commitment Effective Date by facsimile of the new
commitments to be made on such Commitment Effective Date and the amount and final allocation of such commitments applicable to each Lender. Each existing Lender making a commitment as set forth above, and each Eligible Assignee becoming a Lender in
accordance with clause (a) above shall, before 2:00 p.m. (New York City time) on the applicable Commitment Effective Date, make available to the Administrative Agent in immediately available funds (i) in the case of any existing Lender, an
amount equal to such Lender’s commitment and (ii) in the case of any such Eligible Assignee, an amount equal to such Eligible Assignee’s commitment. The Administrative Agent shall promptly make such funds available to the Borrower.

 (d) Each loan advanced by a Lender as a result of such Lender making a commitment pursuant to this Section 2.16, and
each loan advanced by any Eligible Assignee becoming a Lender in accordance with clause (a) above, shall be an “Term Advance” for all purposes hereunder. Each Eligible Assignee becoming a Lender in accordance with clause
(a) above shall be deemed to be a “Lender” for all purposes hereunder. 
 (e) To the extent any Lender
that makes an Advance pursuant to this Section 2.16 already holds a Note or Notes, upon request the Borrower shall promptly execute and deliver to such Lender, with a copy to the Administrative Agent, a new Note, in substantially the form of
Exhibit A-2 hereto, payable to the order of such Lender in a principal amount equal to the Advance made by such Lender pursuant to this Section 2.16. 
 (f) The failure of any Lender that has agreed to an Incremental Commitment pursuant to this Section 2.16 to make an Advance with respect thereto shall not relieve any other Lender that has agreed to
an Incremental Commitment pursuant to this Section 2.16 of its obligation to make an Advance under Section 2.16 but no Lender shall be responsible for the failure of any other Lender to make any Advance under this Section 2.16 on any
Commitment Effective Date.

reasonably be expected to have a Material Adverse Effect, (A) neither the Borrower nor any of its Subsidiaries is undertaking, and has not completed, either individually or together with other potentially responsible parties, any investigation
or assessment or remedial or response action relating to any actual or threatened release, discharge or disposal of Hazardous Materials at any site, location or operation, either voluntarily or pursuant to the order of any governmental or regulatory

the Borrower or any of its Subsidiaries under the Tax Allocation Agreement have been paid, and all amounts due and payable to the Borrower or any of its Subsidiaries under any tax sharing agreement have been received (including amounts by way of
compensation for the use of tax benefits), except as could not reasonably be expected to have a Material Adverse Effect.

 (n) Set forth on Part I of Schedule 4.01(n) is a complete and accurate list of all real property with a book value, as of the

All property and general liability insurance maintained by or on behalf of the Borrower and its Subsidiaries as of the Closing Date is in full force and effect and all premiums that are due and owed have been duly paid, except where the failure to

issued by the FERC, conduct, and cause each of its Subsidiaries to conduct, (i) all transactions with any of the Affiliates of the Borrower on terms that are fair and reasonable and no less favorable to the Borrower or such Subsidiary than it
would obtain in a comparable arm’s-length transaction with a Person not an Affiliate of the Borrower and (ii) all transactions with a Person other than an Affiliate of the Borrower on terms that are without regard to any benefit or
detriment to any Affiliate of the Borrower (other than any Subsidiary); provided that this Section 5.01(i) shall not be deemed to permit any transaction otherwise prohibited by the terms of this Agreement. Without prejudice to the
foregoing, the following transactions shall be deemed to be in compliance with this Section 5.01(i): (A) any agreements made by the Borrower or any of its Subsidiaries with a utility to provide provider of last resort requirements, as such

or any Subsidiary is a party (and any amendments thereto, renewals or replacements thereof on substantially the same terms as determined in good faith by a Responsible Officer of the Borrower or any Subsidiary of the Borrower that is a party
thereto) shall be deemed to comply with this Section 5.01(i) except to the extent that any Governmental Authority determines that any such contract is not in conformance with Applicable Law and such non-conforming contract is not on terms
described in the first sentence of this Section 5.01(i). 
 (j) Further Assurances. Prior to the Collateral Release
Date, promptly upon request by any Agent or any Lender Party, do, execute, acknowledge, deliver, record, re-record, file, re-file, register and re-register any and all such further acts, deeds, conveyances, pledge agreements, mortgages, deeds of

 (k) Preparation of Environmental Reports. If prior to the Collateral Release Date any Agent shall reasonably believe that a material environmental event has occurred on any parcel of real property
owned or leased by the Borrower or any of its Subsidiaries after the date hereof, provide to each Agent within 90 days after receipt of a written request from such Agent in which the Agent describes in reasonable detail the basis of such belief, at
the expense of the Borrower, a Phase I environmental site assessment report for the properties described in such request prepared by an environmental consulting firm reasonably acceptable to the Administrative Agent, indicating the presence or
absence of Hazardous Materials and the estimated cost of any legally required compliance, removal or remedial action in connection with any Hazardous Materials on such properties. Without limiting the generality of the foregoing, if any Agent
determines at any time that a material risk exists that any such report will not be provided within the time referred to above, the Administrative Agent may, at the time following the 45th day after the request of such Agent, retain an environmental consulting firm to prepare such report at the expense of
the Borrower, and the Borrower hereby grants and agrees to cause any Subsidiary that owns any property described in such request to grant at the time of such request to the Administrative Agent, such firm and any agents or representatives thereof an
irrevocable non-exclusive license, subject to the rights of tenants, to enter onto their respective properties to undertake such an assessment.

July 21, 2005 (the “Recorded Term Mortgages”), with such changes to account for (A) local law matters as advised by the Administrative Agent’s local counsel, (B) property/transaction specific matters that
are necessary or desirable in the opinion of the Administrative Agent and (C) any other matters that are necessary or desirable in the opinion of the Administrative Agent; provided that the starting form for such New Mortgage shall be a
Recorded Term Mortgage; and provided further that if the property to be encumbered by a New Mortgage is in a state in which no Recorded Term Mortgage exists, the starting form to be used

  

					
		  	81	  	AESC Credit Agreement

Mortgages that duly executed counterparts of such New Mortgages that are sufficient for recording in all filing or recording offices that the Administrative Agent may deem necessary or desirable in order to create valid and subsisting Liens on the
property described therein in favor of the Collateral Agent for the benefit of the Secured Parties have been delivered to such title insurance company, and evidence reasonably satisfactory to the Administrative Agent that all filing and recording
taxes and fees have been paid; (iii) fully paid American Land Title Association Lender’s Extended Coverage title insurance policies in form and substance, with endorsements and in amounts acceptable to the Administrative Agent, issued by
title insurers acceptable to the Administrative Agent, insuring the New Mortgages to be valid and subsisting Liens on the properties described therein, free and clear of all defects (including mechanics’ Liens and materialmen’s Liens) and

company recording such New Mortgages of the amount previously notified by such title insurance company to the Borrower as necessary for it to record such New Mortgages) that the Administrative Agent may deem necessary or desirable in order to
perfect and protect the liens and security interests created under the Collateral Documents (other than the Other Perfection Requirements) securing all Obligations of the Borrower under the Financing Documents have been taken; provided that
in the case of any Acquired Material Property acquired by or otherwise transferred to the Borrower in connection with a Permitted Asset Swap, the Borrower shall comply with the requirements of the first sentence of this Section 5.01(l) no later
than five days after such acquisition or transfer, whether or not the Administrative Agent shall have made a request therefor. In the event that any additional Advances are made hereunder pursuant to Section 2.16 prior to the Collateral Release
Date, the Borrower shall, within twenty (20) days of each such Advance, obtain from each title insurance company that has issued a mortgagee title insurance policy, a “date down” endorsement (in form and substance reasonably
satisfactory to the Administrative Agent) at the time of each such additional Advance, without increase to the aggregate insured amount of the coverage provided to the Administrative Agent under the Mortgage Policies.

		  	106	  	AESC Credit Agreement

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 or such Arranger
Party’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 the Administrative Agent and each Arranger
Party promptly upon demand for its ratable share of any costs and expenses (including fees and expenses of counsel) payable by the Borrower under Section 8.04, to the extent that the Administrative Agent or such Arranger Party 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 Revolving Lender severally agrees to indemnify each Issuing Bank (to the
extent not promptly reimbursed by the Borrower) from and against such Revolving Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against such Issuing Bank 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 Revolving 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

counsel) payable by the Borrower under Section 8.04, to the extent that such Issuing Bank is not promptly reimbursed for such costs and expenses by the Borrower. 
 (c) For purposes of this Section 7.05, the Lenders’ respective ratable shares of any amount shall be determined, at any time, according to the sum of (i) the aggregate principal amount of
the Advances outstanding at such time and owing to the respective Lenders and (ii) their respective Pro Rata Shares of the L/C Obligations outstanding at such time; provided that the aggregate principal amount of L/C Credit Extensions
owing to any Issuing Bank and the aggregate principal amount of Swing Line Advances owing to the Swing Line Bank shall each be considered to be owed to the Revolving Lenders ratably in accordance with their respective Revolving Commitments. The
failure of any Lender to reimburse the Administrative Agent, any Arranger Party or any Issuing Bank, as the case may be, promptly upon demand for its ratable 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 ratable share of such amount, but no Lender Party shall be responsible for the failure of any other Lender Party to reimburse the

  

					
		  	107	  	AESC Credit Agreement

 
Administrative Agent, any Arranger Party or any Issuing Bank, as the case may be, for such other Lender Party’s ratable share of such amount. Without prejudice to the survival of any other

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 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 Documents. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent shall have become effective, the provisions of this Article VII shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Administrative Agent under the Financing Documents. 
 SECTION 7.07. Liability.
Neither any Agent nor any Arranger Party shall be liable for any error of judgment or for any act done or omitted to be done by it in good faith or for any mistake of fact or law, or for anything it may do or refrain from doing, except to the extent
that any such liability is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted directly and primarily from its gross negligence or willful misconduct. 
 SECTION 7.08. Compensation of Agents. The Administrative Agent shall be entitled to reasonable compensation as may be agreed from
time to time between the Borrower and the Administrative Agent, for all services rendered under this Agreement and the other Financing Documents to which it is a party and such compensation, together with reimbursement of the Administrative Agent in
its individual capacity (and its agency capacity) for its advances, disbursements and reasonable expenses in connection with the performance of the trust and activities provided for herein (including the reasonable fees and 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

  

					
		  	108	  	AESC Credit Agreement

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. No Agent makes any representation as to the value or condition of the security interests
created under the Collateral Documents or any part thereof, or 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 or the Obligations secured under the Collateral Documents, and no Agent (in its individual and agency capacities) shall incur any liability
or responsibility in respect of any such matters. 
 SECTION 7.10. Treatment of Lenders. Each of the Agents may treat the
Lender Parties as the holders of Commitments or L/C Credit Extensions and as the absolute owners thereof for all purposes under this Agreement and the other Financing Documents unless such Agent shall receive notice to the contrary from such Lender
Party. 
 SECTION 7.11. Miscellaneous. (a) Instructions. Each 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 any Agent is to take or not to take in connection therewith under the circumstances then existing, or any Agent is in doubt
as to what action it is required to take or not to take, such 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 any 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. No Agent shall be under any 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 such 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).

to any Federal Reserve Bank, and (B) with respect to any Revolving Commitment, Revolving Advance, L/C Credit Extension or L/C Borrowing, no such assignments shall be permitted without the consent of the Swing Line Bank and 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), except, with respect to the Borrower’s consent only, assignments to any other Lender Party, an Affiliate of any Lender, any Approved Fund or to any Federal Reserve Bank, 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) with respect to Revolving Commitment or Revolving Advance, each such assignment thereof shall be made
on a pro rata basis with respect to each of (A) such Revolving Lender’s Revolving Advances and L/C Credit Extensions and (B) such Revolving Lender’s Revolving 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 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). 
  

					
		  	117	  	AESC Credit Agreement

 (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 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

  

					
		  	118	  	AESC Credit Agreement

 
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 Revolving Commitment or Term Commitment, as the case may be, assumed by it pursuant to such Assignment and Acceptance and, if any assigning Lender has retained a Revolving Commitment or Term
Commitment, as the case may be, hereunder, a new Note to the order of such assigning Lender in an amount equal to the Revolving Commitment or Term Commitment, as the case may be, 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-1 or Exhibit A-2,
as applicable. 
 (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 (i) all or a portion of its Revolving Commitment, the Revolving Advances owing to it, L/C Credit Extensions and the Revolving Note or
Revolving Notes (if any) held by it, and/or (ii) all or a portion of its Term Commitment, the Term Advances owing to it, and the Term Note or Term 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 and/or all or a portion of its Term Commitment, the Term Advances owing to it, and the Term Notes (if any) held by it, (ii) such Lender
Party’s obligations under this Agreement (including its Revolving Commitment and L/C Credit Extensions or Term Commitment, as the case may be) 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 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

  

					
		  	119	  	AESC Credit Agreement

 
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 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

  

					
		  	120	  	AESC Credit Agreement

 
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 and 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

  

					
		  	121	  	AESC Credit Agreement

 
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), 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 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. 
  

					
		  	122	  	AESC Credit Agreement

 (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. 
 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. 
  

					
		  	123	  	AESC Credit Agreement

 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.

 CERTAIN ENVIRONMENTAL MATTERS

 This Schedule incorporates by reference, and reference should be made to, Item 1. Environmental Matters and Item 3. Legal
Proceedings, in Allegheny Energy, Inc.’s Form 10-K for the fiscal year-ended December 31, 2005. 
 Clean Air Act Matters
 
 Allegheny Energy, Inc. (“AYE”) and all of its subsidiaries (collectively
“Allegheny”), including Allegheny Energy Supply Company, LLC (“AE Supply”) currently meet applicable standards for particulate matter emissions at their generation facilities through the use of high-efficiency electrostatic
precipitators, cleaned coal, flue-gas conditioning, optimization software, fuel combustion modifications and, at times, through reduction of output. From time to time, minor excursions of stack emission opacity that are normal to fossil fuel
operations are experienced and are accommodated by the regulatory process. Allegheny meets current emission standards for sulfur dioxide (“SO2”) by using emission controls, burning low-sulfur coal, purchasing cleaned coal (which has lower sulfur content),
blending low-sulfur coal with higher sulfur coal and utilizing emission allowances. 
 Allegheny’s compliance with the
Clean Air Act of 1970 (the “Clean Air Act”) has required, and may require in the future, that Allegheny install post-combustion control technologies on many of its generation facilities. The Clean Air Interstate Rule (“CAIR”)
promulgated by the U.S. Environmental Protection Agency (the “EPA”) on March 10, 2005, may accelerate the need to install this equipment by phasing out a portion of currently available allowances. 
 The Clean Air Act mandates annual reductions of SO2 and created a SO2 emission allowance trading program. AE Supply and Monongahela Power Company (“Mon Power”) comply with current SO
2 emission standards through a system-wide plan combining the
use of emission controls, low sulfur fuel and emission allowances. Based on current forecasts, Allegheny estimates that it may have an SO2 allowance market exposure of less than 10,000 tons in 2006 and approximately 20,000 tons and 75,000 tons in 2007 and 2008,
respectively. Allegheny’s allowance needs, to a large extent, are affected at any given time by the amount of output produced and the types of fuel used by its generation facilities, as well as the implementation of environmental controls.
Therefore, there can be no assurance that Allegheny’s need to purchase SO2 allowances for these periods will not vary from current estimates. Allegheny continues to evaluate options for continuing compliance, and current plans include the installation of scrubbers at its Fort
Martin generation facility by 2010, the elimination of a scrubber bypass at its Pleasants generation facility by 2008 and consideration of scrubbers at its Hatfield generation facility. 
 Allegheny meets current emission standards for nitrogen oxides (“NOX”) by using low NOX burners, Selective Catalytic Reduction, Selective Non-Catalytic Reduction and over-fire air and optimization software, as
well as through the use of emission allowances. Allegheny is currently evaluating its options for CAIR compliance. In 1998, the EPA finalized its NOx State Implementation Plan (“SIP”) call rule (known as the “NOx SIP call”),
which addressed the regional transport of ground-level ozone and required the equivalent of a uniform 0.15 lb/mmBtu emission rate throughout a 22-state region, including Pennsylvania, Maryland and West Virginia. 
 AE Supply and Mon Power are completing installation of NOx controls to meet the Pennsylvania, Maryland and West Virginia
SIP calls. The NOx compliance plan functions on a system-wide basis, similar to the SO2 compliance plan. AE Supply and Mon Power also have the option, in some cases, to

 
purchase alternate fuels or NOx allowances, if needed, to supplement their compliance strategies. AE Supply estimates that its emission control activities, in concert with its inventory of banked
allowances, will facilitate its compliance with NOx limits established by the SIP through 2008. Allegheny’s current capital expenditure forecast includes the expenditure of $2 million of capital costs during 2007 for additional NOX emission controls. Allegheny’s allowance needs, to a large extent,
are affected at any given time by the amount of output produced and the types of fuel used by its generation facilities. Therefore, there can be no assurance that Allegheny’s need to purchase NOX allowances for these periods will not vary from current estimates. 
 On March 15, 2005, the EPA issued the Clean Air Mercury Rule (“CAMR”) establishing a cap and trade system designed to reduce
mercury emissions from coal-fired power plants in two phases during 2010 and 2018. This rule will be implemented through state implementation plans currently under development. The rule has been challenged by several parties. Allegheny is currently
assessing CAMR and its strategy for compliance. The Pennsylvania Department of Environmental Protection (the “PA DEP”) has announced plans to propose a more aggressive mercury control rule in the summer of 2006. Allegheny is assessing the
draft rule to determine what, if any, effect it would have on Allegheny’s Pennsylvania operations that may be above and beyond the requirements of CAMR. 
 Additionally, Maryland passed the Healthy Air Act in early 2006. This legislation imposes state-wide emission caps on SO
2 and NOX, requires mercury requires that greater reductions in mercury emissions be made more quickly than would be
required by CAMR and mandates that Maryland join the Regional Greenhouse Gas Initiative and participate in that coalition’s regional efforts to reduce carbon dioxide emissions. The Act does provide a conditional exemption for the R. Paul Smith
power station, provided that PJM declares the station vital to reliability in the Baltimore/Washington DC metropolitan area. The Maryland Department of the Environment is now charged with developing regulations to implement the requirements of this
legislation. Allegheny is assessing the new legislation to determine what, if any, effect it could have on Allegheny’s Maryland operations. 
 In August 2000, AYE received a letter from the EPA requesting that it provide information and documentation relevant to the operation and maintenance of the following ten electric generation facilities,
which collectively include 22 generation units: Albright, Armstrong, Fort Martin, Harrison, Hatfield’s Ferry, Mitchell, Pleasants, Rivesville, R. Paul Smith and Willow Island. AE Supply and Mon Power own these generation facilities. The letter
requested information under Section 114 of the Clean Air Act to determine compliance with the Clean Air Act and related requirements, including potential application of the new source review (“NSR”) standards of the Clean Air Act,
which can require the installation of additional air pollution control equipment when the major modification of an existing facility results in an increase in emissions. AYE has provided responsive information to this and a subsequent request. At
this time, AYE is engaged in discussions with the EPA with respect to environmental matters, including NSR issues. 
 If NSR
requirements are imposed on Allegheny’s generation facilities, in addition to the possible imposition of fines, compliance would entail significant capital investments in pollution control technology. There are three recent, significant federal
court decisions that have addressed the application of NSR requirements to electric utility generation facilities: the Ohio Edison decision, the Duke Energy decision and the Alabama Power decision. The Ohio Edison decision is favorable to the EPA.
The Duke Energy and Alabama Power decisions support the industry’s understanding of NSR requirements. The U.S. Court of Appeals for the Fourth Circuit affirmed the Duke Energy decision on June 15, 2005. 
 On May 20, 2004, AYE, AE Supply, Mon Power and West Penn Power Company (“West Penn”) received a Notice of Intent to Sue
Pursuant to Clean Air Act §7604 (the “Notice”) from the Attorneys General of New York, New Jersey and Connecticut and from PA DEP. The Notice alleged that Allegheny made major modifications to some of its West Virginia facilities in
violation of the Prevention of Significant Deterioration (“PSD”) provisions of the Clean Air Act at the following coal-fired facilities: Albright Unit No. 3; Fort Martin Units No. 1 and 2; Harrison Units No. 1, 2 and 3;
Pleasants Units No. 1 and 2 and Willow Island Unit No. 2. The Notice also alleged PSD violations at the Armstrong, Hatfield’s Ferry and Mitchell generation facilities in Pennsylvania and identifies PA

 
DEP as the lead agency regarding those facilities. On September 8, 2004, AYE, AE Supply, Mon Power and West Penn received a separate Notice of Intent to Sue from the Maryland Attorney
General that essentially mirrored the previous Notice. 
 On January 6, 2005, AE Supply and Mon Power filed a declaratory
judgment action against the Attorneys General of New York, Connecticut and New Jersey in federal District Court in West Virginia (“West Virginia DJ Action”). This action requests that the Court declare that AE Supply’s and Mon
Power’s coal-fired generation facilities in Pennsylvania and West Virginia comply with the Clean Air Act. The Attorneys General filed a motion to dismiss the West Virginia DJ Action. It is possible that the EPA and other state authorities may
join or move to transfer the West Virginia DJ Action. 
 On June 28, 2005, the PA DEP and the Attorneys General of New
York, New Jersey, Connecticut and Maryland filed suit against AYE, AE Supply and Mon Power, The Potomac Edison Company and West Penn (collectively, the “Distribution Companies”) in the U.S. District Court for the Western District of
Pennsylvania (the “PA Enforcement Action”). This action alleges NSR violations under the federal Clean Air Act and the Pennsylvania Air Pollution Control Act at the Hatfield’s Ferry, Armstrong and Mitchell facilities in Pennsylvania.
The PA Enforcement Action appears to raise the same issues regarding Allegheny’s Pennsylvania generation facilities that are before the federal District Court in the West Virginia DJ Action, except that the PA Enforcement Action also includes
the PA DEP and the Maryland Attorney General. Allegheny’s motion to stay the PA Enforcement Action was denied on November 21, 2005. On January 17, 2006, the PA DEP and the Attorneys General filed an amended complaint. On
February 15, 2006, Allegheny filed a motion to dismiss the amended complaint. 
 In 2003, the EPA issued the Equipment
Replacement Rule, which sets forth a clearer set of rules for projects that may be undertaken without triggering NSR requirement. This rule would apply the Routine Maintenance, Repair and Replacement (“RMRR”) exception to the NSR
requirement in a manner that is more consistent with the energy industry’s historical compliance approach. That rule was challenged by some states and environmental groups and, on December 24, 2003, the U.S. Court of Appeals for the
District of Columbia Circuit issued an order to stay the implementation of that rule. On March 17, 2006, the Court issued a final decision declaring the rule unauthorized under the Clean Air Act. NSR requirements will continue to be interpreted
under the pre-rule regulations and case law. Allegheny had established an NSR review process under the original regulatory program and does not expect the March 2006 circuit court decision in this matter to have any significant impact on its
operations. At this time, AYE and its subsidiaries are not able to determine the effect that these actions may have on them. 
 On February 16, 2005, Citizens for Pennsylvania’s Future, an environmental group, sued Allegheny in the U.S. District Court for the Western District of Pennsylvania. The action alleges violations of opacity limits and particulate
matter emission limits at the Hatfield’s Ferry generation facility. 
 Allegheny intends to vigorously pursue and defend
against the environmental matters described above but cannot predict their outcomes. 
 Canadian Toxic-Tort Class
Action
 On June 30, 2005, AE Supply, Mon Power and Allegheny Generating Company (“AGC”), along with 18
other companies with coal-fired generation facilities, were named as defendants in a toxic-tort, purported class action lawsuit filed in the Ontario Superior Court of Justice. On behalf of a purported class comprised of all persons residing in
Ontario within the past six years (and/or their family members or heirs), the named plaintiffs allege that the defendants negligently failed to prevent their generation facilities from emitting air pollutants in such a manner as to cause death and
multiple adverse health effects, as well as economic damages, to the plaintiff class. The plaintiffs seek damages in the approximate amount of Canadian $49.1 billion (approximately US $41.6 billion, assuming an exchange rate of 1.18 Canadian dollars
per US dollar), along with continuing damages in the amount of Canadian $4.1 billion per year and punitive damages of Canadian $1.0 billion (approximately US $3.5 billion and US $850 million, respectively, assuming an exchange rate of 1.18 Canadian
dollars per US dollar) along with such other relief as the Court deems just. Allegheny has not yet been served with this lawsuit. Allegheny intends to vigorously defend against this action but cannot predict its outcome. 

 Claims Related to Alleged Asbestos Exposure
 The Distribution Companies have been named as defendants, along with multiple other defendants, in pending asbestos cases alleging bodily
injury involving multiple plaintiffs and multiple sites. These suits have been brought mostly by seasonal contractors’ employees and do not involve allegations of either the manufacture, sale or distribution of asbestos-containing products by
Allegheny. These asbestos suits arise out of historical operations and are related to the installation and removal of asbestos-containing materials at Allegheny’s generation facilities. Allegheny’s historical operations were insured by
various foreign and domestic insurers, including Lloyd’s of London. Asbestos-related litigation expenses have to date been reimbursed in full by recoveries from these historical insurers, and Allegheny believes that it has sufficient insurance
to respond fully to the asbestos suits. Certain insurers, however, have contested their obligations to pay for the future defense and settlement costs relating to the asbestos suits. Allegheny is currently involved in two asbestos insurance-related
actions, Certain Underwriters at Lloyd’s, London et al. v. Allegheny Energy, Inc. et al., Case No. 21-C-03-16733 (Washington County, Md.), and Monongahela Power Company et al. v. Certain Underwriters at Lloyd’s London and
London Market Companies, et al., Civil Action No. 03-C-281 (Monongalia County, W.Va.). The parties in these actions are seeking an allocation of responsibility for historic and potential future asbestos liability. 
 Allegheny and numerous others are plaintiffs in a similar action filed against Zurich Insurance Company in California, Fuller-Austin
Asbestos Settlement Trust, et al. v. Zurich-American Insurance Co., et al., Case No. CGC 04 431719 (Superior Court of California, County of San Francisco). 
 In connection with a settlement, Allegheny received payment from one of its insurance companies in the amount of $625,000 on July 5, 2005, with the next payment of $625,000 due July 1, 2006. As
part of the settlement, Allegheny released this insurance company from potential liabilities associated with claims against Allegheny alleging asbestos exposure. 
 Allegheny does not believe that the existence or pendency of either the asbestos suits or the actions involving its insurance will have a material impact on its consolidated financial position, results of
operations or cash flows. Allegheny believes that it has established adequate reserves, net of insurance receivables and recoveries, to cover existing and future asbestos claims. As of December 31, 2005, Allegheny had 930 open cases remaining
in West Virginia and five open cases remaining in Pennsylvania. 
 Allegheny intends to vigorously pursue these matters but
cannot predict their outcomes. 
 Comprehensive Environmental Response Compensation and Liability Act of 1980 (“CERCLA”)
Claim
 On March 4, 1994, Mon Power and certain affiliated companies received notice that the EPA had identified
them as potentially responsible parties (“PRPs”) with respect to the Jack’s Creek/Sitkin Smelting Superfund Site in Pennsylvania. Initially, approximately 175 PRPs were involved; however, the current number of active PRPs has been
reduced as a result of settlements with de minimis contributors and other contributors to the site. The costs of remediation will be shared by all past and active responsible parties. In 1999, a PRP group that included Mon Power and certain
affiliated companies entered into a consent order with the EPA to remediate the site. It is currently estimated that the total remediation costs to be borne by all of the responsible parties will not exceed $30.0 million. Allegheny has an accrued
liability representing its estimated share of the remediation costs as of March 31, 2006. 

 PADEP Administrative Order – Forward Township Landslide 
 On March 7, 2005, The Pennsylvania Department of Environmental Protection (PADEP) issued an Administrative Order to Allegheny requesting
records pertaining to coal supply and ash management practices at Mitchell Power Station for the period 1945-1955. PADEP is conducting an investigation of a landslide in Forward Township, Allegheny County, PA believed to contain combustion
materials. Allegheny is fully cooperating with the investigation and has provided responsive material. Nothing found to date indicates that coal combustion by-products from the Mitchell Power Station were used for fill in the area in question. At
this time, Allegheny is not able to determine the effect that this action may have on it.

 FORM OF REVOLVING NOTE 
  

			
	$            	 	Dated:                  ,
        

 FOR VALUE RECEIVED, the undersigned, ALLEGHENY ENERGY SUPPLY COMPANY, LLC, a Delaware
limited liability company (the “Borrower”), HEREBY PROMISES TO PAY
                             (the “Revolving Lender”) for the account of its
Applicable Lending Office (as defined in the Credit Agreement referred to below) the aggregate principal amount of the Revolving Advances, L/C Advances and Swing Line Advances (in each case as defined in the Credit Agreement referred to below) owing
to the Revolving Lender by the Borrower pursuant to the Credit Agreement dated as of May 2, 2006, (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 Swing Line Bank, the Issuing Bank, and Citicorp USA, Inc., 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 Revolving Advance, L/C Advance or Swing Line Advance from the date of such Revolving Advance, L/C Advance or Swing Line 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 Citicorp USA, Inc., as Administrative Agent, at Two Penns Way, New Castle, DE 19720 in immediately available funds. Each Revolving Advance, L/C Advance or Swing Line Advance owing to the Revolving Lender by the Borrower, and all
payments made on account of principal thereof, shall be recorded by the Revolving Lender and, prior to any transfer hereof, endorsed on the grid attached hereto, which is part of this Revolving Note; provided, however, that the failure of the
Revolving Lender to make any such recordation or endorsement shall not affect the Obligations of the Borrower under this Revolving Note. 
 This Revolving 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 Revolving
Advances, L/C Advances and Swing Line Advances by the Revolving 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
Revolving Advance, L/C Advance or Swing Line 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. The obligations of the Borrower under this Revolving Note and the other Financing Documents with respect to the Revolving Advances, L/C

 FORM OF TERM NOTE 
  

			
	$            	 	Dated:                  ,
        

 FOR VALUE RECEIVED, the undersigned, ALLEGHENY ENERGY SUPPLY COMPANY, LLC, a Delaware
limited liability company (the “Borrower”), HEREBY PROMISES TO PAY                      (the “Term
Lender”) for the account of its Applicable Lending Office (as defined in the Credit Agreement referred to below) the aggregate principal amount of the Term Advances (as defined in the Credit Agreement referred to below) owing to the
Term Lender by the Borrower pursuant to the Credit Agreement dated as of May 2, 2006, (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 Swing Line Bank, the Issuing Bank, and Citicorp USA, Inc., 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 Term Advance from the date of such Term 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 Citicorp USA, Inc., as Administrative Agent, at
Two Penns Way, New Castle, DE 19720 in immediately available funds. Each Term Advance owing to the Term Lender by the Borrower, and all payments made on account of principal thereof, shall be recorded by the Term Lender and, prior to any transfer
hereof, endorsed on the grid attached hereto, which is part of this Term Note; provided, however, that the failure of the Term Lender to make any such recordation or endorsement shall not affect the Obligations of the Borrower under this Term
Note. 
 This Term 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 Term Advances by the Term 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 Term Advance being evidenced by this Term 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. The obligations of the Borrower under this Term Note and the other Financing Documents with respect to the Term Advances are secured by the
Collateral as provided in the Financing Documents.

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

chattel paper, deliver and pledge to the Collateral Agent hereunder such note or instrument or chattel paper duly indorsed and accompanied by duly executed instruments of transfer or assignment, all in form and substance satisfactory to the

statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Administrative Agent may reasonably request, in order to perfect and preserve the security interest granted or purported to be
granted by the Grantor hereunder; (D) deliver and pledge to the Collateral Agent for benefit of the Secured Parties certificates representing Security Collateral that constitutes certificated securities, accompanied by undated stock or bond
powers executed in blank; (E) take all action necessary to ensure that the Collateral Agent has control of Collateral consisting of deposit accounts, investment property and letter-of-credit rights as provided in Sections 9-104, 9-106 and
9-107 of the UCC and, at the request of the Administrative Agent, electronic chattel paper and transferable records as provided in Section 9-105 of the UCC and in Section 16 of UETA; (F) if an Event of Default has occurred and is
continuing, take all action to ensure that the Collateral Agent’s security interest is noted on any certificate of ownership related to any Collateral evidenced by a certificate of ownership; (G) if an Event of Default has occurred and is
continuing, cause the Collateral Agent to be the beneficiary under all letters of credit that constitute Collateral, with the exclusive right to make all draws under such letters of credit, and with all rights of a transferee under
Section 5-114(e) of the UCC; and (H) deliver to the Collateral Agent evidence that all other action that the Administrative Agent may deem reasonably necessary or desirable to perfect and protect the security interest created by the
Grantor under this Agreement has been taken. 
 (b) The Grantor hereby authorizes the Collateral Agent to file one or more
financing or continuation statements, and amendments thereto, including one or more financing statements indicating that such financing statements cover all assets or all personal property (or words of similar effect) of the Grantor, in each case

Agreement or any financing statement covering the Collateral or any part thereof shall be sufficient as a financing statement where permitted by law. The Grantor ratifies its authorization for the Collateral Agent to have filed such financing
statements, continuation statements or amendments filed prior to the date hereof.

efforts to maintain all (i) electronic chattel paper so that the Collateral Agent has control of the electronic chattel paper in the manner specified in Section 9-105 of the UCC and (ii) all transferable records so that the Collateral
Agent has control of the transferable records in the manner specified in Section 16 of the Uniform Electronic Transactions Act, as in effect in the jurisdiction governing such transferable record (“UETA”); 
 (b) the Grantor will use commercially reasonable efforts to maintain all letter-of-credit rights assigned to the Collateral

industry and in accordance with Applicable Laws (including Environmental Laws), except where the failure to comply with such Applicable Laws could not reasonably be expected to have a Material Adverse Effect. 
 Section 5.10 Insurance. (a) The Grantor will, or will cause its Subsidiaries to, maintain property damage and liability
insurance in accordance with the terms of the Financing Documents. Each policy of the Grantor for liability insurance shall provide for all losses to be paid on behalf of the Collateral Agent and the Grantor as their interests may appear. Each
endorsement or certificate of insurance for such policy (other than with respect to any policy of liability insurance) shall in addition (i) name the Collateral Agent, and name or cover the Grantor, in each case, as insured parties thereunder
(without any representation or warranty by or obligation upon the Collateral Agent) as their interests may appear, (ii) provide that at least ten days’ prior written notice of cancellation or of lapse shall be given to the Collateral Agent
by the insurer and (iii) not provide for any recourse against any Creditor Party for the payment premiums or other amounts with respect thereto. The Grantor will, at the request of the Collateral Agent, which shall be no more than once

possession or control of a warehouseman, bailee or agent, and the Collateral Agent so requests, the Grantor will (i) notify such warehouseman, bailee or agent of the security interest created

  

					
	Security Agreement	  	14	  	

 
hereunder, (ii) instruct such warehouseman, bailee or agent to hold all such Collateral solely for the Collateral Agent’s account subject only to the Collateral Agent’s
instructions (which shall permit such Collateral to be removed by the Grantor in the ordinary course of business until the Collateral Agent notifies such warehouseman, bailee or agent that an Event of Default has occurred and is continuing),
(iii) use commercially reasonable efforts, to cause such warehouseman, bailee or agent to authenticate a record acknowledging that it holds possession of such Collateral for the Collateral Agent’s benefit and shall act on the instructions
of the Collateral Agent without the further consent of the Grantor or any other Person, and (iv) make such authenticated record available to the Collateral Agent. 
 (c) Except as otherwise provided in this subsection (c), the Grantor will continue to collect, at its own expense, all amounts due or to become due the Grantor under the Assigned Agreements, Receivables
and Related Contracts. In connection with such collections, the Grantor may take such action as the Grantor may deem necessary or advisable to enforce collection of the Assigned Agreements, Receivables and Related Contracts; provided that the
Collateral Agent shall have the right at any time upon the occurrence and during the continuance of an Event of Default and upon written notice to the Grantor of its intention to do so, to notify the obligors under any Assigned Agreements,
Receivables and Related Contracts of the assignment of such Assigned Agreements, Receivables and Related Contracts to the Collateral Agent and to direct such obligors to make payment of all amounts due or to become due to the Grantor thereunder
directly to the Collateral Agent and, upon such notification and at the expense of the Grantor, to enforce collection of any such Assigned Agreements, Receivables and Related Contracts, to adjust, settle or compromise the amount or payment thereof,
in the same manner and to the same extent as the Grantor might have done, and to otherwise exercise all rights with respect to such Assigned Agreements, Receivables and Related Contracts, including those set forth set forth in Section 9-607 of
the UCC. After receipt by the Grantor of the notice from the Collateral Agent referred to in the proviso to the preceding sentence, (i) all amounts and proceeds (including instruments) received by the Grantor in respect of the Assigned
Agreements, Receivables and Related Contracts of the Grantor shall be received in trust for the benefit of the Collateral Agent hereunder, shall be segregated from other funds of the Grantor and shall be forthwith paid over to the Collateral Agent
in the same form as so received (with any necessary indorsement) to be deposited in the Enforcement Proceeds Account and applied as provided in Section 6.06 and (ii) the Grantor will not adjust, settle or compromise the amount or payment
of any Receivable or amount due on any Assigned Agreement or Related Contract, release wholly or partly any obligor thereof, or allow any credit or discount thereon. The Grantor will not permit or consent to the subordination of its right to payment
under any of the Assigned Agreements, Receivables and Related Contracts to any other indebtedness or obligations of the obligor thereof.

reasonable steps, including in the U.S. Patent and Trademark Office, the U.S. Copyright Office and any other Governmental Authority, to (i) maintain the validity and enforceability of such material Intellectual Property Collateral and maintain
such material Intellectual Property Collateral in full force and effect, except expirations or terminations in the ordinary course, and (ii) pursue the registration and maintenance of each unexpired patent,

reexamination, opposition, cancellation, infringement and misappropriation proceedings. The Grantor shall not, without the written consent of the Administrative Agent, discontinue use of or otherwise abandon any Intellectual Property Collateral, or
abandon any right to file an application for patent, trademark, or copyright, unless the Grantor shall have previously determined that such use or the pursuit or maintenance of such Intellectual Property Collateral is no longer desirable in the
conduct of the Grantor’s business and that the loss thereof would not be reasonably likely to have a Material Adverse Effect. 
 (b) Where required by Applicable Law, the Grantor shall use proper statutory notice in connection with its use of each item of its Intellectual Property Collateral, except to the extent failure to do so could not reasonably be expected to
have a Material Adverse Effect. 
 (c) The Grantor shall take all steps which it or the Collateral Agent (as directed by the
Administrative Agent) deems reasonable and appropriate to preserve and protect each item of its Intellectual Property Collateral, including taking all reasonable steps necessary to ensure that all licensed users of any of the Trademarks use such
consistent standards of quality, except to the extent failure to do so could not reasonably be expected to have a Material Adverse Effect.

hereby does) assign to the Collateral Agent its rights (including its contingent rights) to the proceeds of all Related Contracts consisting of letters of credit of which it is or hereafter becomes a beneficiary or assignee. 
 (b) Upon the occurrence and during the continuance of an Event of Default, the Grantor will, promptly upon request by the Collateral Agent,
(i) notify (and the Grantor hereby authorizes the Collateral Agent to notify) the issuer and each nominated person with respect to each of the Related Contracts consisting of letters of credit that the proceeds thereof have been assigned to the
Collateral Agent hereunder and any payments due or to become due in respect thereof are to be made directly to the Collateral Agent or its designee and (ii) arrange for the Collateral Agent to become the transferee beneficiary of letter of
credit.

continuing:

pertaining to the Security Collateral of the Grantor or any part thereof for any purpose; provided that the Grantor will not exercise or refrain from exercising any such right if such action would violate this Agreement; 
  

					
	Security Agreement	  	16	  	

 (iii) the Grantor shall be entitled to receive and retain any and all
dividends, interest and other distributions paid in respect of the Security Collateral of the Grantor if and to the extent that the payment thereof is not otherwise prohibited by the terms of the Financing Documents; and

and other instruments as the Grantor may reasonably request for the purpose of enabling the Grantor to exercise the voting and other rights that it is entitled to exercise pursuant to paragraph (i) above and to receive the dividends or interest
payments that it is authorized to receive and retain pursuant to paragraph (ii) above. In the absence of instructions to vote or exercise other rights, the Collateral Agent shall not be obligated and shall incur no liability for its failure to
take any action in respect of such rights. 
 (b) Upon the occurrence and during the continuance of an Event of Default:

 (ii) all rights of the Grantor (A) to exercise or refrain from exercising the voting and other consensual

and other distributions that it would otherwise be authorized to receive and retain pursuant to Section 5.14(a)(ii) shall, upon notice to the Grantor by the Collateral Agent (as instructed by the Administrative Agent), automatically cease, and
all such rights shall thereupon become vested in the Collateral Agent, which shall thereupon have the sole right to exercise or refrain from exercising such voting and other consensual rights (in each case, as instructed by the Administrative Agent)
and to receive and hold as Security Collateral such dividends, interest and other distributions; and 
 (iii) all
dividends, interest and other distributions that are received by the Grantor contrary to the provisions of paragraph (i) of this Section 5.14(b) shall be received in trust for the benefit of the Collateral Agent, shall be segregated from
other funds of the Grantor and shall be forthwith paid over to the Collateral Agent as Security Collateral in the same form as so received (with any necessary indorsement).

intervention in such proceeding or otherwise, (a) to file and prove a claim for the whole amount of the Senior Debt Obligations owing and unpaid and to file such other papers or documents as may be necessary or advisable in order to have the

Collateral Agent pursuant to the terms of this Agreement or any other Collateral Document. The Collateral Agent shall, on behalf and for the benefit of the Secured Parties, be the beneficiary and hold and safeguard any Collateral delivered to it
during the term of this Agreement or any other Collateral Document as specified herein or therein and shall hold such Collateral in accordance with the provisions of this Agreement or such other Collateral Document, as the case may be;

	Security Agreement	  	21	  	

 
be required to hold or safeguard the Collateral with a higher degree of care than it holds and safeguards its own property. 
 Section 7.05 The Collateral Agent May Perform. If the Grantor fails to perform any agreement contained herein, the Collateral
Agent may, but without any obligation to do so and without notice, itself perform, or cause performance of, such agreement, and the expenses of the Collateral Agent incurred in connection therewith shall be payable by the Grantor under
Section 9.01. 
 Section 7.06 Duties. (a) The powers conferred on the Collateral Agent hereunder are
solely to protect the Secured Parties’ interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received
by it hereunder, the Collateral Agent shall have no duty as to any Collateral, as to ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Collateral, whether or not any
Secured Party has or is deemed to have knowledge of such matters, or as to the taking of any necessary steps to preserve rights against any parties or any other rights pertaining to any Collateral. The Collateral Agent shall be deemed to have
exercised reasonable care in the custody and preservation of any Collateral in its possession if such Collateral is accorded treatment substantially equal to that which it accords its own property. 
 (b) Anything contained herein to the contrary notwithstanding, the Collateral Agent may from time to time, when the Collateral Agent deems
it to be necessary, appoint one or more subagents (each, a “Subagent”) for the Collateral Agent hereunder with respect to all or any part of the Collateral. In the event that the Collateral Agent so appoints any Subagent with
respect to any Collateral, (i) the assignment and pledge of such Collateral and the security interest granted in such Collateral by the Grantor hereunder shall be deemed for purposes of this Agreement to have been made to such Subagent, in
addition to the Collateral Agent, for the ratable benefit of the Secured Parties, as security for the Secured Obligations of the Grantor, (ii) such Subagent shall automatically be vested, in addition to the Collateral Agent, with all rights,
powers, privileges, interests and remedies of the Collateral Agent hereunder with respect to such Collateral, and (iii) the term “Collateral Agent”, when used herein in relation to any rights, powers, privileges, interests and
remedies of the Collateral Agent with respect to such Collateral, shall include such Subagent; provided that no such Subagent shall be authorized to take any action with respect to any such Collateral unless and except to the extent expressly
authorized in writing by the Collateral Agent. 
 (c) The Collateral Agent shall not be deemed to have knowledge of (i) the
occurrence of any Default or Event of Default (or if any such event would occur after giving effect to any application of funds contemplated by any provision of this Agreement) unless and until it has received written notice thereof from the Grantor
or any other Creditor Party or (ii) the existence, the content, or the terms and conditions of, any other agreement, instrument or document, in each case, to which it is not a party, whether or not referenced herein. Without prejudice to the
foregoing, the Collateral Agent shall not be attributed with any knowledge or information that any other department or division of Citibank or any of its Affiliates may have from time to time. 
  

					
	Security Agreement	  	22	  	

 (d) The parties hereto agree that any of the acknowledgements, consents, agreements and
statements made by the Collateral Agent in respect of the Collateral in the Financing Documents are being made in its capacity as directed agent for, and on behalf and at the request of, the Secured Parties and that such acknowledgements, consents,
and agreements are being made without independent investigation and without liability as a principal. The parties hereto understand and agree that, notwithstanding any other term of the Financing Documents, in making any determinations, taking
actions, granting consents, refraining from taking actions, withholding consents contemplated in the Financing Documents, the Collateral Agent is authorized, and should be expected, to consult with legal and other advisors and with the other
Creditor Parties and their respective advisors. The Collateral Agent shall not incur any liability for any determination made or instruction given by the Required Lenders and their respective advisors. The Collateral Agent assumes no responsibility
and shall not be deemed to have assumed any responsibility, either express or implied, to monitor the validity or sufficiency of the Collateral. The Creditor Parties further acknowledge and agree that the provisions of the Financing Documents which
empower and/or entitle the Collateral Agent to take action, to refrain to take action, or to request the taking or refraining from taking action, with respect to the Collateral or otherwise shall not impose, and shall not be deemed to impose, on the
Collateral Agent an obligation to act independently from the instructions of the Creditor Parties or to monitor the contingencies that may give rise to the exercise of such power or entitlement. 
 Section 7.07 Liability. The Collateral Agent shall not be liable for any error of judgment or for any act done or omitted to be
done by it in good faith or for any mistake of fact or law, or for anything it may do or refrain from doing, except to the extent that any such liability is found in a final, non-appealable judgment by a court of competent jurisdiction to have
resulted directly and primarily from its gross negligence or willful misconduct. 
 Section 7.08 Successor Collateral
Agent. (a) The Required Lenders may remove the Collateral Agent at any time by giving to the Collateral Agent 30 days’ prior written notice of removal. The Collateral Agent may resign at any time by giving to the Administrative Agent
and the Grantor 15 days’ prior written notice of resignation. 
 (b) Within 30 days after giving the foregoing notice of
removal to the Collateral Agent or within 15 days after receiving the foregoing notice of resignation from the Collateral Agent, the Required Lenders shall appoint a successor collateral agent and give notice of such successor collateral agent to
the Collateral Agent. If no successor collateral agent shall have been so appointed by the Required Lenders, and shall have accepted such appointment, within 15 days after the retiring Collateral Agent’s giving of notice of resignation or 30
days after the Required Lenders’ removal of the retiring Collateral Agent, then the retiring Collateral Agent may on behalf of the other Secured Parties apply to a court of competent jurisdiction for appropriate relief or appoint a successor
collateral agent, which shall be a Creditor Party; provided that if no Creditor Party is willing to become the successor collateral agent, then such successor Collateral Agent shall be a commercial bank (or any Affiliate thereof) organized
under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as the Collateral Agent hereunder by a successor Collateral Agent, such
successor Collateral Agent shall thereupon succeed to and become vested with all the rights, powers, discretion, privileges and

  

					
	Security Agreement	  	23	  	

 
duties of the retiring Collateral Agent and the retiring Collateral Agent shall be discharged from its duties and obligations under this Agreement and the other Financing Documents. After any
retiring Collateral Agent’s resignation or removal hereunder as the Collateral Agent, the provisions of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Collateral Agent under
this Agreement or any other Financing Document. 
 (c) Upon receipt of notice of the identity of the successor collateral agent,
the Collateral Agent shall deliver all Collateral then held hereunder to the successor collateral agent, less the Collateral Agent’s fees, costs, expenses and the value of other obligations owed to the Collateral Agent hereunder, or hold such
funds (or any portion thereof) and such other Collateral (if any) pending distribution, until all such fees, costs and expenses or the value of other obligations are paid to it. 
 Section 7.09 Suits, Etc., Brought by the Collateral Agent. In any suit, proceeding or action brought by the Collateral Agent in
its individual capacity (and in its capacity as agent hereunder) under or with respect to the Collateral for any sum owing under this Agreement or any other Financing Document, or to enforce any provisions hereof or thereof, the Grantor will save,
indemnify and keep the Collateral Agent in its individual capacity (and in its capacity as trustee or agent hereunder) harmless from and against all expense, loss or damage (including reasonable attorney’s fees and documented expenses) suffered
by reason of any defense, setoff, counterclaim, recoupment or reduction of liability whatsoever of the obligee thereunder, arising out of a breach by the Grantor of any of its obligations hereunder or thereunder or arising out of any other
agreement, indebtedness or liability at any time owing to, or in favor of, such obligee or its successors from the Grantor, and all such obligations of the Grantor shall be and remain enforceable against and only against the Grantor, and shall not
be enforceable against the Collateral Agent (in its individual capacity) or any other Creditor Party. 
 Section 7.10
Compensation of the Collateral Agent. The Collateral Agent shall be entitled to reasonable compensation as may be agreed from time to time between the Grantor and the Collateral Agent for all services rendered under this Agreement and the
other Financing Documents to which it is a party and such compensation, together with reimbursement of the Collateral Agent in its individual capacity (and its agency capacity) for its advances, disbursements and reasonable expenses in connection
with the performance of the trust and activities provided for herein (including the reasonable fees and expenses of its agents and of counsel, accountants and other experts), shall be paid in full by the Grantor promptly following demand from the
Collateral Agent from time to time as services are rendered and expenses are incurred. All such payments made by the Grantor to the Collateral 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 Creditor Party shall have any liability
for any fees, expenses or disbursements of the Collateral Agent. Any reasonable and documented fees, compensation, indemnity amounts (unless such indemnity amounts are subject to dispute among the parties hereto) or expenses of the Collateral Agent

	Security Agreement	  	24	  	

 
Article IX. Upon its resignation or removal, the Collateral Agent shall be entitled to the prompt payment by the Grantor 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 7.10 shall survive any resignation or removal of the Collateral Agent and the termination of the other provisions of this Agreement. 
 Section 7.11 Taxes, Stamp and Other Similar Taxes. (a) The Grantor shall pay or reimburse the Collateral Agent upon request
for any transfer taxes or other taxes relating to or incurred in connection with the Collateral and shall indemnify and hold harmless the Collateral Agent from any amounts that it is obligated to pay in the way of such taxes. Any payments of income
from the Collateral shall be subject to withholding regulations then in force with respect to United States federal taxation. Upon the Collateral Agent’s request, the Grantor and each Lender will promptly provide the Collateral Agent with the
appropriate Form W-9 for tax identification number certifications, or Form W-8BEN, for non-resident alien certifications. The Collateral Agent shall be responsible only for income reporting to the Internal Revenue Service with respect to income
earned on the Collateral. This Section 7.11 shall survive the termination of this Agreement and the resignation or removal of the Collateral Agent. 
 (b) The Grantor agrees to indemnify and hold harmless the Collateral Agent (in its individual and agency capacity), and each other Creditor Party from, and shall reimburse the Collateral Agent (in its
individual or agency capacity) and each other Creditor Party for any present or future claim for liability for any stamp or other similar tax and any penalties or interest with respect thereto, which may be assessed, levied or collected by any
jurisdiction in connection with the Financing Documents, and the Collateral created hereunder or under any other Collateral Document or the attachment or perfection of the security interest granted to the Collateral Agent in any Collateral. The
obligations of the Grantor under this Section 7.11 shall survive the resignation or removal of the Collateral Agent or the termination of the other provisions of this Agreement. 
 Section 7.12 Limitation on Duties in Respect of Collateral. Beyond its express duties set forth in this Agreement or in the
other Financing Documents to which it is a party and the duty to exercise reasonable care as to the custody thereof, and the accounting to the Grantor and the Secured Parties for moneys received hereunder, the Collateral Agent shall not have any
duty (implied or otherwise) to the Grantor or the Secured Parties with respect to any Collateral in its possession or control or in the possession or control of its agent or nominee, any income thereon, or the priority or preservation of rights
against prior parties or any other rights pertaining thereto. The Collateral Agent shall be deemed to have exercised reasonable care with respect to any collateral in its possession or control or in the possession or control of its agents or nominee
if such Collateral is accorded treatment substantially equal to that which the Collateral Agent accords its own property. To the extent, however, that the Collateral Agent or an agent or nominee of the Collateral Agent maintains possession or
control of any of the Collateral or the Collateral Documents at any office of the Collateral Agent, the Collateral Agent shall, or shall instruct such agent or nominee to, grant the Grantor and the other Secured Parties reasonable access to such
Collateral (other than, except to the extent permitted pursuant to Article IV, the

  

					
	Security Agreement	  	25	  	

 
Account Collateral and all funds and financial assets (including security entitlements and Cash Equivalents) from time to time on deposit in, or credited to, any thereof) or Collateral Documents
as they previously notified the Collateral Agent to be required for the conduct of their businesses, except, in the case of the Grantor, if an Event of Default has occurred and is continuing and to the extent that the Collateral Agent shall have
taken Enforcement Action. 
 Section 7.13 Right to Initiate Judicial Proceedings, Etc. Upon the occurrence and
during the continuance of an Event of Default (a) the Collateral Agent shall have the right and power to institute and maintain such suits and proceedings as it may deem appropriate to protect and enforce the rights vested in the Collateral
Agent by this Agreement and the other Financing Documents; and (b) the Collateral Agent may, either after entry or without entry proceed by suit or suits at law or in equity to enforce such rights and to foreclose upon the Collateral and to
realize upon all or, from time to time, any of the property pledged hereunder for the benefit of the Secured Parties under the judgment or decree of a court of competent jurisdiction. 
 Section 7.14 Exculpatory Provisions. (a) The Collateral Agent does not make any representation as to the value or condition
of the security interests created hereunder or any part thereof, or as to the title of the Grantor 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, the Secured Obligations and the Collateral Agent (in its individual and agency capacities) shall not incur any liability or responsibility
in respect of any such matters. 
 (b) Except as expressly provided for or referenced in any Financing Document to which it is a
party, the Collateral Agent shall not be responsible for or under, nor chargeable with knowledge of the existence, the content, or the terms and conditions of, any other agreement, instrument or document. The Collateral Agent shall not be attributed
with any knowledge or information that any other department or division of Citibank or any of Citibank’s Affiliates may have from time to time. 
 (c) All notices, certifications, approvals, directions, instructions or other communication given to the Collateral Agent with respect to, or otherwise relating to, this Agreement or the other Financing
Documents, in each case, by any Creditor Party or the Administrative Agent (whether on its own behalf or on behalf of the Secured Parties (or any class thereof)) shall be given in writing, signed by an Authorized Signatory of such Person and, except
as otherwise expressly required under the Financing Documents, the Collateral Agent shall not be required to take any action under any Financing Document unless it has received such written instructions. 
 Section 7.15 Treatment of Creditor Parties. (a) The Collateral Agent may treat the holders of Senior Debt Obligations as
the absolute owners thereof for all purposes under this Agreement and the other Financing Documents unless it shall receive notice to the contrary from any Creditor Party or the Administrative Agent. 
 (b) Any Person that shall be designated as the duly authorized representative of one or more of the Grantor or Creditor Parties to act as
such in connection with any matters

  

					
	Security Agreement	  	26	  	

 
pertaining to this Agreement, any other Financing Document or the Collateral shall present to the Collateral Agent such documents, including opinions of counsel, as the Collateral Agent may
reasonably request, in order to demonstrate to the Collateral Agent the authority of such Person to act as the representative of the Grantor or such Creditor Parties. 
 Section 7.16 Miscellaneous. (a) The Collateral Agent shall have the right at any time to seek instructions concerning the administration of its duties and obligations hereunder or any
other Financing Documents from the Required Lenders or any court of competent jurisdiction. In the event there is any disagreement between the other parties to this Agreement and the terms of this Agreement or any other applicable Financing Document
do not unambiguously mandate the action the Collateral Agent is to take or not to take in connection therewith under the circumstances then existing, or the Collateral Agent is in doubt as to what action it is required to take or not to take, the
Collateral Agent 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) None of the provisions of this Agreement or the other Financing Documents shall be construed to require the Collateral 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 Collateral Agent shall not be under any 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 Grantor or any Creditor Party, (i) if any action it has been requested or directed to take would be contrary to Applicable Law, or (ii) unless such
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). 
 Section 7.17 Indemnification. Each of the Lenders agrees to indemnify the Collateral
Agent (to the extent not promptly reimbursed by the Grantor), ratably according to the respective amounts of the Senior Debt Obligations owed to such Creditor Party from time to time, from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind of nature whatsoever that may be imposed on, incurred by, or asserted against the Collateral Agent in any way relating to or arising out of this Agreement or
any other Financing Document to which it is a party or any action taken or omitted by the Collateral Agent under this Agreement or any other Financing Document to which it is a party (collectively, the “Indemnified Costs”);
provided that no such Creditor Party shall be liable for any portion of the Indemnified Costs found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted directly and primarily from the Collateral
Agent’s gross negligence or willful misconduct. Without limiting the foregoing, each of the Lenders agrees to reimburse the Collateral Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including reasonable counsel
fees and disbursements) incurred by the Collateral Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement or any other Financing Document, to the extent that the Collateral Agent is not reimbursed for such

  

					
	Security Agreement	  	27	  	

 
expenses by the Grantor. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.17 shall apply. 
 Section 7.18 Publicity. No printed or other material in any language, including prospectuses, notices, reports, and promotional
material which mentions “Citibank, N.A.” by name or the rights, powers, or duties of the Collateral Agent under this Agreement or any other Financing Document shall be issued by any of the parties hereto, or on such a party’s
behalf, without the prior written consent of the Collateral Agent. 
 Section 7.19 Merger; Consolidation. Any
corporation into which the Collateral Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Collateral Agent shall be a party, or any corporation
succeeding to the business of the Collateral Agent shall be the successor of the Collateral Agent hereunder without the execution or filing of any paper with any party hereto or any further act on the part of any of the parties hereto except where
an instrument of transfer or assignment is required by law to effect such succession, anything herein to the contrary notwithstanding.

asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or resulting from the Financing Documents (including enforcement of this Agreement), except to the extent such claim, damage, loss, liability or

obligations under the Credit Agreement (including all or any portion of its Commitment, the Advances owing to it and the Note or Notes, if any, held by it) to any other Person, and such other Person shall thereupon become vested with all the

under Section 2.06 of the Credit Agreement. Upon the release of any item of Collateral from the security interest granted hereby pursuant to this Section 9.08(a), any representation, warranty or covenant contained herein relating to such

 EXHIBIT E 
 AESC CREDIT AGREEMENT 
 INTERCREDITOR TERMS 
 Terms defined in the Senior Credit Agreement referred to below are used in these Intercreditor Terms with their defined meanings except as
otherwise defined herein. 
 Section 1. Senior Secured Obligations. Citicorp USA, Inc., as administrative agent (the
“Senior Agent”), and the Lenders Parties (the Lender Parties, Citibank, N.A., in its capacity as Collateral Agent, and the Senior Agent are herein referred to collectively as the “Senior Secured
Creditors”) have entered into that certain Credit Agreement dated as of May [    ], 2006 (the “Senior Credit Agreement”) with Allegheny Energy Supply Company, LLC, as Borrower (the
“Borrower”). Pursuant to the Collateral Documents, the Borrower has granted to the Senior Secured Creditors a security interest in certain real and personal property of the Borrower (the “Collateral”).
The Senior Credit Agreement, the Collateral Documents and all documents and agreements executed in connection with the Senior Credit Agreement are referred to herein as the “Senior Loan Documents.” 
 Section 2. Junior Secured Obligations. [            ] (the
“Hedging Counterparty”) has entered into [ describe Commodity Hedge Agreement ] dated as of             ,
            (the “Junior Hedge Agreement”) with the Borrower. The Borrower may, from time to time (whether before or after the date hereof), enter into one or
more Commodity Hedge Agreements with the Hedging Counterparty or any other Person (each such other Person, an “Other Junior Hedging Counterparty”). So long as the Hedging Counterparty and any such Other Junior Hedging
Counterparty shall have entered into an accession agreement substantially in the form of Annex A hereto (the “Accession Agreement”), the Borrower may, from time to time prior to the Collateral Release Date (whether before or
after the date hereof), grant to the Hedging Counterparty and such Other Junior Hedging Counterparty (collectively, the “Junior Secured Creditors”), respectively, a security interest in the Collateral pursuant to the Junior
Collateral Documents; provided that, notwithstanding the foregoing, the Borrower shall be permitted to grant the security interests permitted under Section 5.02(a)(vi) and (viii) of the Senior Credit Agreement to the Hedging
Counterparty and Other Junior Hedging Counterparties without any such Person being a party to, or otherwise executing an Accession Agreement in respect of, an agreement with the Senior Agent containing these Intercreditor Terms. “Junior
Collateral Documents” means all security agreements, pledge agreements, mortgages and other agreements creating any Lien in favor of the Junior Secured Creditors; the Junior Hedge Agreement, Commodity Hedge Agreements with Other Junior
Hedging Counterparties, the Junior Collateral Documents and all other documents and agreements executed in connection with the Junior Hedge Agreement and Commodity Hedge Agreements with Other Junior Hedging Counterparties are collectively referred
to herein as the “Junior Hedge Documents.” 
 SECTION 3. No Third Party Beneficiaries; No Fiduciary
Duties. All undertakings, agreements, representations and warranties contained in these Intercreditor Terms are solely for the benefit of the Senior Secured Creditors and the Junior Secured Creditors, and there are no other parties (including,
without limitation, the Borrower or any of its Affiliates)

  

 1 

 
who are intended to be benefited in any way by these Intercreditor Terms. The existence of these Intercreditor Terms shall not commit or obligate the Senior Secured Creditors or the Junior
Secured Creditors to make loans or extend credit to the Borrower. The parties hereto agree that these Intercreditor Terms, the Senior Loan Documents and the Junior Hedge Documents do not create an agency or fiduciary relationship between the Senior
Secured Creditors, the Senior Agent or any Junior Secured Creditor. 
 SECTION 4. Reservation of Security Interests as
Against Other Parties. Nothing contained in these Intercreditor Terms is intended to affect or limit in any way the security interests and/or liens of the Senior Secured Creditors and the Junior Secured Creditors in, or on, any or all of the
property and assets of the Borrower or other Persons, whether tangible or intangible, insofar as the Borrower and other Persons are concerned. The Senior Secured Creditors and the Junior Secured Creditors specifically reserve all respective security
interests and/or liens and rights to assert such security interests and/or liens as against the Borrower and other Persons. 
 SECTION 5. Priority of Security Interests. Irrespective of (a) the time, order, manner or method of creation, attachment or perfection of the respective security interests and/or liens granted to the Senior Secured Creditors and
the Junior Secured Creditors in or on any or all of the Collateral, (b) the time or manner of the filing of their respective financing statements or other public filing documents, (c) whether the Senior Secured Creditors or the Junior
Secured Creditors, or any bailee or agent thereof, holds possession of, or has exercised control over, any or all of the Collateral, (d) the dating, execution, authentication or delivery of any agreement, document or instrument granting the
Senior Secured Creditors or the Junior Secured Creditors security interests and/or liens in or on any or all of the Collateral, (e) the giving or failure to give notice of the security interests or of the acquisition or expected acquisition of
any purchase money or other security interest in Collateral, (f) the status of the Junior Secured Creditors as “purchasers” of the Collateral entitled to protection or priority with respect to the Collateral under the UCC, and
(g) any provision of the UCC or any other applicable law to the contrary: 
 (i) any Lien on the Collateral
securing the First Lien Obligations (as hereinafter defined) now or hereafter held by or for the benefit of the Senior Secured Creditors, regardless of how acquired, whether by grant, statute, operation of law, subrogation or otherwise, shall be
senior in all respects and prior to any Lien on the Collateral securing the Second Lien Obligations (as hereinafter defined). Without prejudice to the foregoing, all Liens on the Collateral securing the First Lien Obligations shall be and remain
senior to all Liens on the Collateral securing the Second Lien Obligations for all purposes, whether or not such Liens securing the First Lien Obligations are subordinated to any Lien securing any other obligation of the Borrower; 
 (ii) any Lien on the Collateral securing the Second Lien Obligations now or hereafter held by or for the benefit of the
Junior Secured Creditors, regardless of how acquired, whether by grant, statute, operation of law, subrogation or otherwise, shall be junior and subordinate in all respects to all Liens on the Collateral securing the First Lien Obligations; and

  

 2 

 (iii) for purposes of the foregoing allocation of priorities, any claim of a
right of set-off shall be treated in all respects as a security interest and no claimed right of set-off shall be asserted to defeat or diminish the rights or priorities provided for herein. 
 In these Intercreditor Terms, (a) “First Lien Obligations” means any payment, performance or other obligation of the Borrower
of any kind under the Senior Loan Documents, including, without limitation, any liability of the Borrower on any claim, whether or not the right of any creditor to payment in respect of such claim is reduced to judgment, liquidated, unliquidated,
fixed, contingent, matured, disputed, undisputed, legal, equitable, secured or unsecured, and whether or not such claim is discharged, stayed or otherwise affected by any Insolvency Proceeding. Without limiting the generality of the foregoing, the
First Lien Obligations under the Senior Loan Documents include (i) the obligation to pay principal, interest, Letter of Credit reimbursement obligations, Letter of Credit commissions, charges, expenses, fees, reasonable attorneys’ fees and
disbursements, indemnities and other amounts payable by the Borrower under any Senior Loan Document, (ii) the payment of interest accrued or accruing (or which would, absent the commencement of any Insolvency Proceeding, accrue), after
commencement of an Insolvency Proceeding in accordance with the rate specified in the applicable Senior Loan Document whether or not the claim for such interest is allowed as a claim in such Insolvency Proceeding and (iii) the obligation of the
Borrower to reimburse any amount in respect of any of the foregoing that any Senior Secured Creditor, in its sole discretion (after demand has been made upon the Borrower), may elect to pay or advance on behalf of the Borrower; and
(b) “Second Lien Obligations” means any payment, performance or other obligation of the Borrower of any kind under the Junior Hedge Documents, including, without limitation, any liability of such Person on any claim,
whether or not the right of any creditor to payment in respect of such claim is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, disputed, undisputed, legal, equitable, secured or unsecured, and whether or not such claim is
discharged, stayed or otherwise affected by any Insolvency Proceeding. Without limiting the generality of the foregoing, the Junior Lien Obligations of the Borrower under the Junior Hedge Documents include (i) the obligation to pay principal,
interest, charges, expenses, fees, reasonable attorneys’ fees and disbursements, indemnities and other amounts payable by the Borrower under any Junior Hedge Document, (ii) the payment of interest accrued or accruing (or which would,
absent the commencement of any Insolvency Proceeding, accrue), after commencement of an Insolvency Proceeding in accordance with the rate specified in the applicable Junior Hedge Document whether or not the claim for such interest is allowed as a
claim in such Insolvency Proceeding and (iii) the obligation of the Borrower to reimburse any amount in respect of any of the foregoing that any Junior Secured Creditor, in its sole discretion (after demand has been made upon the Borrower), may
elect to pay or advance on behalf of the Borrower. 
 SECTION 6. Exercise of Remedies. (a) So long as the First Lien
Obligations have not been paid in full (as hereinafter defined), whether or not any Insolvency Proceeding has been commenced by or against the Borrower or any of its Subsidiaries, (i) no Junior Secured Creditor shall (A) exercise or seek
to exercise any rights or remedies with respect to any Collateral securing the Second Lien Obligations, (B) institute any action or proceeding with

  

 3 

 
respect to such rights or remedies (including, without limitation, any action of foreclosure, contest or protest) or (C) object to any foreclosure proceeding or action brought by any Senior
Secured Creditor or the exercise of any right under any Senior Loan Document or similar agreement or arrangement to which any Senior Secured Creditor is a party, or any other exercise by any such party of any rights and remedies relating to the
Collateral under the Senior Loan Documents or otherwise, or, except as provided herein, any release of any or all of the Collateral for any purpose, or object to the forbearance by Senior Secured Creditors from bringing or pursuing any foreclosure
proceeding, or object, oppose or otherwise contest any claim for allowance in any Insolvency Proceeding of First Lien Obligations consisting of post-petition interest, fees and expenses or action or any other exercise of any rights or remedies
relating to the Collateral; provided that any Junior Secured Creditor may exercise any or all such rights or remedies after the passage of a period of at least 180 days has elapsed since the date on which the Senior Agent has been notified in
writing by one or more Junior Secured Creditors that the aggregate amount due and payable by the Borrower in respect of Commodity Hedge Agreements constituting Second Lien Obligations that have been terminated is in excess of $100,000,000 (the
“Standstill Period”); provided further that notwithstanding anything to the contrary herein, in no event shall any Junior Secured Creditor exercise any rights or remedies with respect to the Collateral if,
notwithstanding the expiration of the Standstill Period, the Senior Agent or the Senior Secured Creditors shall have commenced and be diligently pursuing the exercise of their rights or remedies with respect to all or any material portion of the
Collateral (prompt notice of such exercise to be given to the Junior Secured Creditors); and (ii) subject to the rights of the Junior Secured Creditors under clause (i) above, the Senior Secured Creditors shall have the exclusive right to
enforce rights, exercise remedies and make determinations regarding release, disposition, or restrictions with respect to the Collateral without any consultation with or the consent of the Junior Secured Creditors, and the Junior Secured Creditors
shall take any action reasonably requested by the Senior Agent in order to effectuate any such enforcement, exercise, release or disposition; provided however that (w) the Junior Secured Creditors may exercise any rights or remedies
after the termination of the Standstill Period to the extent permitted by Section 6(a)(i), (x) in any Insolvency Proceeding commenced by or against the Borrower, any Junior Secured Creditor may file a claim or statement of interest,
(y) any Junior Secured Creditor may take any action not adverse to the Senior Secured Creditors in order to preserve or protect its rights in the Collateral and any Junior Secured Creditor may act in coordination with and not adverse to the
Senior Secured Creditors in exercising any remedies initiated by the Senior Secured Creditors with respect to the Collateral. 
 (b) Each Junior Secured Creditor agrees that it shall not, with respect to the Second Lien Obligations, take or receive from or on behalf of the Borrower or any Subsidiary of the Borrower, directly or indirectly, in cash or other property
or by setoff, counterclaim or in any other manner (whether pursuant to any enforcement, collection, execution, levy, foreclosure action or other proceeding or otherwise) any Collateral or any proceeds of Collateral, unless and until all First Lien
Obligations have been paid in full. Without limiting the generality of the foregoing, unless and until the First Lien Obligations have been paid in full, except as expressly provided herein, the sole right of the Junior Secured Creditors with
respect to the Collateral is to hold a Lien on the Collateral pursuant to the Junior Hedge Documents for the period and to the extent granted therein and to receive a share of the proceeds thereof, if any, after payment in full of the First Lien
Obligations; provided however that subject to Section 5 and this Section 6, nothing in this paragraph shall be construed to impair the right of the Junior Secured Creditors to

  

 4 

 
receive payments of principal, interest, fees and other amounts in respect of the Second Lien Obligations as provided for in the Junior Hedge Documents, and to enforce the making of such payments
by bringing suit at law (but not, except as provided in Section 6(a)(i) above, to exercise any rights in respect of their Liens on the Collateral) with respect to any unpaid amounts of such payments. Each Junior Secured Creditor
(i) further agrees that it will not take any action that would hinder, delay, limit, impede or prohibit any exercise of remedies by the Senior Agent or any of the Senior Secured Creditors to the extent related to satisfying the First Lien
Obligations, including any collection, sale, lease, exchange, transfer or other disposition of the Collateral, whether by foreclosure or otherwise, or that would limit, invalidate, avoid or set aside any Lien or Senior Loan Document securing or
purporting to secure the First Lien Obligations or subordinate the priority of the First Lien Obligations to the Second Lien Obligations or grant the Liens securing the Second Lien Obligations equal ranking to the Liens securing the First Lien
Obligations and (ii) hereby waives any and all rights it may have (other than as specified herein) as a junior lien creditor or otherwise (whether arising under the UCC or under any other applicable law) to object to the manner in which the
Senior Secured Creditors seek to enforce or collect the First Lien Obligations or the Liens now or hereafter granted in any Collateral to secure the First Lien Obligations, regardless of whether any action or failure to act by or on behalf of the
Senior Secured Creditors is adverse to the interest of the Junior Secured Creditors. 
 (c) In these Intercreditor Terms,
“paid in full” and “payment in full” means, with respect to any and all First Lien Obligations, (i) payment in full thereof in cash (or otherwise to the written satisfaction of the Senior Secured
Creditors with respect to such First Lien Obligations), (ii) in the case of any outstanding Letter of Credit issued by an Issuing Bank, receipt of cash collateral (or a backstop letter of credit in respect thereof on terms acceptable to such
Issuing Bank and the Senior Agent) in an amount equal to 101% of the aggregate amount available for drawing under such Letter of Credit or the return and cancellation of such Letter of Credit, and (iii) termination of the Commitments under the
Senior Credit Agreement and any other commitment to lend and all other Obligations of the Senior Secured Creditor under the Senior Loan Documents. 
 SECTION 7. Release of Collateral. (a) The Junior Secured Creditors agree that any collection, sale or other disposition of any or all of the Collateral by the Senior Secured Creditors (whether
pursuant to the UCC or otherwise) shall be free and clear of any and all security interests, liens, claims and/or rights of the Junior Secured Creditors in such Collateral. At the request of the Senior Agent, the Junior Secured Creditors shall
promptly provide the Senior Agent with any necessary or appropriate releases to permit the collection, sale or other disposition of any or all of the Collateral by the Senior Secured Creditors free and clear of the security interests and liens of
the Junior Secured Creditors. In addition, at the request of the Senior Agent, the Junior Secured Creditors shall, to the extent necessary or appropriate, promptly release any and all security interests, liens, claims and/or rights which it may have
on or in the Collateral to facilitate the collection, sale or other disposition of such Collateral by the Borrower or the Senior Secured Creditors. 
 (b) Without prejudice to the foregoing, each Junior Secured Creditor also hereby agrees and acknowledges that, upon the Collateral Release Date, all Liens securing its Second Lien Obligations shall be
released. 
  

 5 

 (c) Each Junior Secured Creditor shall promptly execute and deliver such release documents
and instruments and shall take such further actions as the Senior Agent shall request to evidence any release of the second-priority Lien described in this Section 7. Each Junior Secured Creditor hereby appoints the Senior Agent and any officer
or duly authorized person of the Senior Agent, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power of attorney in the place and stead of such Junior Secured Creditor and in the name of the Junior
Secured Creditor or in the Senior Agent’s own name, from time to time, in the Senior Agent’s sole discretion, for the purposes of carrying out the terms of this clause, to take any and all appropriate action and to execute and deliver any
and all documents and instruments as may be necessary or desirable to accomplish the purposes of this paragraph, including, without limitation, any financing statements, endorsements, assignments, releases or other documents or instruments of
transfer (which appointment, being coupled with an interest, is irrevocable). 
 SECTION 8. Turnover of Collateral.
Unless and until all First Lien Obligations shall have been paid in full, any Collateral or proceeds thereof or any payment received by any Junior Secured Creditor from proceeds of the Collateral (including assets or proceeds received in connection
with the exercising rights or remedies after the expiration of the Standstill Period in accordance with Section 6(a)(i)) shall be segregated and held in trust and forthwith paid over to the Senior Agent for application to the First Lien
Obligations, whether due or not due, in the same form as received, with any necessary endorsements or as a court of competent jurisdiction may otherwise direct, and, until so delivered, the same shall be held in trust by such Junior Secured Creditor
as the property of the Senior Secured Creditors. The Senior Agent is hereby authorized to make any and all such endorsements as agent for any such Junior Secured Creditor. This authorization is coupled with an interest and is irrevocable.

 SECTION 9. Nonavoidability and Perfection. (a) Each Junior Secured Creditor agrees that it will not directly or
indirectly take any action to contest or challenge in any proceeding (including, without limitation, any Insolvency Proceeding), (i) the validity, legality, enforceability, perfection, priority or avoidability of any Senior Loan Document or the
security interest of the Senior Secured Creditors in the Collateral or (ii) the reasonableness of any action or failure to act by the Senior Agent or the Senior Secured Creditors in respect of the Collateral, including, without limitation, the
Collateral Release Date or the timing, method or manner of (A) any consent to disposition by the Borrower of any Collateral or (B) disposing of or liquidating any Collateral, the terms, including the price and percentage of consideration
received in cash, of any such disposition or liquidation, or any failure to dispose of or liquidate any Collateral, including acceptance of Collateral by the Senior Secured Creditors in full or partial satisfaction of the indebtedness secured by the
Collateral Documents; and 
 (b) Each of the Senior Agent and each Senior Secured Creditor (by its acceptance of the benefits of
the Senior Loan Documents) agrees that it shall not, and hereby waives any right to, contest, or support any other Person in contesting, in any proceeding (including, without limitation, any Insolvency Proceeding), the priority, validity or

 SECTION 10. Refinancing. (a) Notwithstanding anything in the Junior Hedge
Documents to the contrary, the Obligations under the Senior Credit Agreement may be Refinanced (as hereinafter defined) at any time, without notice to, or consent of, any of the Junior Secured Creditors, without affecting the Lien priority and
subordination or other provisions of this Agreement; provided that (i) the holders (or an agent or trustee thereof) of such Refinancing debt shall have entered into an Accession Agreement at the time of such Refinancing unless such
holders (or an agent or trustee thereof) are already bound by the terms of this Agreement in respect of such Obligations and (ii) the aggregate principal amount of such replacement first lien Obligations shall not be in excess of the sum of
(A) $2,000,000,000 plus (B) any amounts due in connection with any Refinancing thereof (including interest (including post-petition and default rate interest), commitment fees, letter of credit fees, premiums, fees, costs and
expenses and any amounts necessary to cash collateralize any Letters of Credit outstanding thereunder) plus (C) the aggregate amount of reasonable transaction fees and expenses (including reasonable accounting, legal, investment banking,
consultant, title company and rating agency fees and expenses) incurred by the Borrower in connection with such Refinancing. In these Intercreditor Terms, “Refinance” means, in respect of any Obligation, to refinance, extend,
renew, defease, amend, modify, supplement, restructure, replace, refund or repay, or to issue other indebtedness, in exchange or replacement for, such Obligation in whole or in part; and “Refinanced” and
“Refinancing” shall have correlative meanings. 
 (b) If, at any time concurrently with or after the First Lien
Obligations are deemed for purposes of this Agreement “paid in full”, the Borrower or any of its Subsidiaries enters into a Refinancing of the First Lien Obligation in accordance with the foregoing provisions, then the obligations under
such Refinancing shall automatically and immediately be treated as First Lien Obligations for all purposes of this Agreement, including for purposes of the Lien priorities and rights in respect of Collateral set forth herein, and the first lien
collateral agent under the documents and other instruments evidencing such Refinancing (the “New First Lien Agent”) shall be deemed to be the Senior Agent, and such agreements and other instruments shall be “Senior Loan
Documents” for all purposes of this Agreement. Upon receipt of a notice stating that the Borrower has entered into a new Senior Loan Document (which notice shall include the identity of the New First Lien Agent), each Junior Secured Creditor
shall promptly enter into such documents and agreements (including amendments or supplements to this Agreement) as the Borrower (or such other Person) or such New First Lien Agent may reasonably request in order to provide to the Senior Agent the
rights contemplated hereby, in each case consistent in all material respects with the terms of this Agreement. 
 SECTION 11.
Insurance Proceeds. In the event of the occurrence of any casualty with respect to any of the Collateral, the Junior Secured Creditors agrees that the Senior Agent, on behalf of the Senior Secured Creditors, shall have the sole and exclusive
right to adjust, compromise or settle any such loss with the insurer thereof, and to collect and receive the proceeds from such insurer. Any insurer shall be fully protected if it acts in reliance on the provisions of this paragraph. 
 SECTION 12. Waiver of Certain Rights. The Junior Secured Creditors hereby waive any and all rights to (a) require the Senior
Secured Creditors to marshal any property or assets of the Borrower or to resort to any of the property or assets of the Borrower or any other Person in any particular order or manner, or (b) require the Senior Secured Creditors to enforce

  

 7 

 
any guaranty or any security interest or lien given by the Borrower or any other any Person to secure the payment of any or all of the indebtedness secured by the Collateral Documents as a
condition precedent or concurrent to taking any action against or with respect to the Collateral. 
 SECTION 13. Bankruptcy
Financing Issues. (a) These Intercreditor Terms shall continue in full force and effect after the filing of any petition for relief by or against the Borrower under the United States Bankruptcy Code (the “Code”) and all
converted or succeeding cases in respect thereof (all references herein to the Borrower being deemed to apply to such Person as a debtor-in-possession and to a trustee for such Person) with respect to all Collateral and to all indebtedness evidenced
by the Senior Loan Documents and the Junior Hedge Documents, including indebtedness incurred by the Borrower, subsequent to such filing. 
 (b) If the Borrower shall become subject to a proceeding under the Code, and if the Senior Secured Creditors shall desire to permit the use of cash collateral by the Borrower or to provide post-petition
financing from the Senior Secured Creditors to the Borrower, the Junior Secured Creditors agrees as follows: (i) adequate notice to the Junior Secured Creditors shall be deemed to have been provided for such use of cash collateral or such
post-petition financing if the Junior Secured Creditors receive notice thereof to the extent required by Rule 4001(b) or any successor thereto under the Code; and (ii) no objection will be raised by the Junior Secured Creditors to any such use
of cash collateral or such post-petition financing from the Senior Secured Creditors so long as the Junior Secured Creditors’ lien is not adversely affected thereby. 
 (c) No objection will be raised by (i) the Junior Secured Creditors to any Senior Secured Creditor’s motion for relief from automatic stay in any such proceeding to foreclose on, sell or
otherwise realize upon the Collateral and (ii) any Senior Secured Creditor to the Junior Secured Creditors’ motion for relief from automatic stay in any such proceeding to foreclose on, sell or otherwise realize upon the Collateral,
provided such foreclosure and sale is consistent with the terms of these Intercreditor Terms. 
 SECTION 14. Assignment of
Indebtedness. Each of the Senior Agent, on behalf of the Senior Secured Creditors, and the Hedging Counterparty, represents and warrants that, as of the date hereof, it has not previously assigned any interest in any of the indebtedness or other
obligations evidenced by the Senior Loan Documents or the Junior Hedge Documents, as the case may be, other than assignments permitted by the Senior Credit Agreement and the Junior Hedge Agreement. The Senior Agent, on behalf of the Senior Secured
Creditors, and Hedging Counterparty, each covenant and agree that the assignment of any indebtedness or other obligations evidenced by the Senior Loan Documents and the Junior Hedge Documents owing to such Hedging Counterparty shall be subject to
the terms, provisions and conditions of these Intercreditor Terms and that the assignee thereof shall be bound by the terms, provisions and conditions of these Intercreditor Terms. 
 SECTION 15. Term. As between the Senior Secured Creditors on the one hand and the Hedging Counterparty on the other hand, these
Intercreditor Terms shall remain in full force and effect until the earliest of (a) all First Lien Obligations have been paid in full, (b) all Second Lien Obligations have been paid in full and the Senior Agent has received agreement(s),
duly executed by the Hedging Counterparty, releasing all security interests in respect of the Collateral granted to the Hedging Counterparty by the Borrower to secure the Second Lien

  

 8 

 
Obligations (other than any security interest permitted under Section 5.02(a)(vi) and (viii) of the Senior Credit Agreement), together with evidence of duly filed UCC termination
statements for all financing statements previously filed in respect of such security interests or (c) the Collateral Release Date has occurred and the Senior Agent has received agreement(s), duly executed by the Hedging Counterparty, releasing
all security interests in respect of the Collateral granted to the Hedging Counterparty by the Borrower to secure the Second Lien Obligations (other than any security interest permitted under Section 5.02(a)(vi) and (viii) of the Senior
Credit Agreement), together with evidence of duly filed UCC termination statements for all financing statements previously filed in respect of such security interests. These Intercreditor Terms shall continue to be effective or be reinstated, as the
case may be, if at any time any payment of any of the indebtedness evidenced by the Senior Loan Documents is rescinded or must otherwise be returned by any Senior Secured Creditor upon the insolvency, bankruptcy or reorganization of the Borrower or
otherwise, all as though such payment had not been made. This is a mutual and continuing agreement of subordination and the Senior Secured Creditors may continue to extend credit or other financial accommodations and loan monies to or for the
benefit of the Borrower, on the faith hereof, under the Senior Loan Documents or otherwise without notice to the other party hereto. 
 SECTION 16. Waiver of Defenses. The rights of the Senior Secured Creditors under these Intercreditor Terms shall not be adversely affected by (a) any lack of validity or enforceability of any Senior Loan Document or any
agreement or instrument relating thereto; (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the obligations evidenced by the Senior Loan Documents or the obligations of the Borrower under or in
respect of the Senior Loan Documents; (c) any amendment or waiver of or any consent to departure from any Senior Loan Document, including, without limitation, any increase in the obligations resulting from the extension of additional credit to
the Borrower or any of its Subsidiaries or otherwise; (d) any taking, exchange, release or non-perfection of any Collateral or any other collateral, or any taking, release or amendment or waiver of, or consent to departure from, any other
guaranty, for all or any of the obligations evidenced by the Senior Loan Documents; (e) any manner of application of Collateral or any other collateral, or proceeds thereof, to all or any of the obligations evidenced by the Senior Loan
Documents, or any manner of sale or other disposition of any Collateral or any other collateral for all or any of the obligations evidenced by the Senior Loan Documents or any other obligations of the Borrower under the Senior Loan Documents or any
other assets of the Borrower or any of its Subsidiaries; (f) any change, restructuring or termination of the corporate structure or existence of the Borrower or any of its Subsidiaries; (g) any failure of any Senior Secured Creditor to
disclose to the Junior Secured Creditors any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of the Borrower now or hereafter known to such Senior Secured Creditor (the
Junior Secured Creditors waiving any duty on the part of the Senior Secured Creditors to disclose such information); or (h) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on
any representation by any Senior Secured Creditor that might otherwise constitute a defense available to the Junior Secured Creditors. 
 SECTION 17. Reliance, Waiver of Notices: No Representations and Management of Credit Facilities. All of the indebtedness evidenced by the Senior Loan Documents shall be deemed to have been made or incurred in reliance upon these
Intercreditor Terms. The Senior

  

 9 

 
Secured Creditors and the Junior Secured Creditors (a) expressly waive all notices not specifically required pursuant to the terms of these Intercreditor Terms and (b) agree that no
Person has made any representation or warranty with respect to the due execution, legality, validity, completeness or enforceability of any of the respective documents to which the Senior Secured Creditor and the Junior Secured Creditors are a
party, the perfection or priority of any security interest or lien securing any or all of the indebtedness evidenced by the Senior Loan Documents or the Junior Hedge Documents or the collectibility of the indebtedness evidenced by the Senior Loan
Documents or the Junior Hedge Documents. No party shall have any liability to the other for any loss, claim or damage allegedly suffered by such other party in any proceeding to foreclose or otherwise enforce any of its security interests in and/or
liens on any of the assets or properties of the Borrower or any other Person. 
 SECTION 18. Financial Condition of the
Borrower. Each of the Senior Secured Creditors and the Junior Secured Creditors hereby assumes responsibility for keeping themselves informed of the financial condition of the Borrower and its Subsidiaries and of all other circumstances bearing
upon the risk of nonpayment of the indebtedness evidenced by the Senior Loan Documents and the Junior Hedge Documents that diligent inquiry would reveal and each such party also hereby agrees that no other party shall have any duty to advise any
other of any information regarding such condition or any such circumstances. 
 SECTION 19. Notices. (a) Any notice,
request, demand, consent or other communication hereunder shall be in writing and delivered in person or sent by telecopy or registered or certified mail, return receipt requested and postage prepaid, to the applicable party at its address or

written notice of the aggregate amount of the Second Lien Obligations then outstanding owed by the Borrower to the Hedging Counterparty under the applicable Junior Hedge Documents and any other information that the Senior Agent may reasonably
request. 
 (c) Upon the written request of the Hedging Counterparty, the Senior Agent shall provide written notice of the
aggregate amount of the First Lien Obligations then outstanding under the Senior Loan Documents and any other information that the Hedging Counterparty may reasonably request. 
 SECTION 20. UCC Notices. If the Senior Secured Creditors or the Junior Secured Creditors shall be required by the UCC or any other
applicable law to give notice of any action taken or to be taken with respect to any or all of the Collateral, such notice shall be given in accordance with Section 17 above and ten (10) days’ notice shall be conclusively deemed to be
commercially reasonable.

these Intercreditor Terms, shall be effective only in the specific instance and for the specific purpose for which given. 
 SECTION 23. Waiver; Failure or Delay. No failure or delay on the part of the Senior Secured Creditors and the Junior Secured Creditors in the exercise of any power, right, remedy or privilege under these Intercreditor Terms shall
impair such power, right, remedy or privilege or shall operate as a waiver thereof; nor shall any single or partial exercise of any such power, right, remedy or privilege preclude any other or further exercise of any other power, right, remedy or

a                      corporation (the “Subordinated Creditor”) and ALLEGHENY ENERGY SUPPLY COMPANY, LLC, a Delaware
limited liability company (the “Borrower”), in favor of Citicorp USA, Inc., as Administrative Agent (the “Administrative Agent”) under the Credit Agreement dated as of May 2, 2006, (as amended,

 PRELIMINARY
STATEMENTS: 
 (1) The Borrower intends to become indebted to the Subordinated Creditor in the principal amount of
$                 to be evidenced by
                        , and may hereafter from time to time become indebted or otherwise obligated to the Subordinated
Creditor in further amounts. All indebtedness and other obligations of the Borrower to the Subordinated Creditor now or hereafter existing (whether created directly or acquired by assignment or otherwise), and interest and premiums, if any, thereon
and other amounts payable in respect thereof or in connection therewith, are hereinafter referred to as the “Subordinated Debt”. 
 (2) Under the Credit Agreement it is a condition to the incurrence of the Subordinated Debt that the Subordinated Creditor[, as owner of
             percent of the outstanding shares of stock of the Borrower,] shall have executed and delivered this Agreement. 
 NOW, THEREFORE, in consideration of the premises, the Subordinated Creditor and the Borrower each hereby agrees as follows: 
 SECTION 1. Subordination. (a) The Subordinated Creditor hereby subordinates the Subordinated Debt to the Senior Debt Obligations to
the extent and in the manner hereinafter set forth in this Agreement. 
 (b) Except during the continuance of a Default
(including the commencement and continuation of any Insolvency Proceeding relating to any Material Subsidiary), the Subordinated Creditor may receive regularly scheduled payments from the Borrower on account of the Subordinated Debt. After the
occurrence and during the continuance of any Default (including the commencement and continuation of any Insolvency Proceeding relating to any Material Subsidiary), however, unless the Required Lenders otherwise agree, the Subordinated Creditor
shall not demand, accept or take any action to collect any payment on account of the Subordinated Debt. 
  

					
	AESC Credit Agreement	  	F-1	  	

 (c) In any Insolvency Proceeding relating to the Borrower or any Material Subsidiary, the
Subordinated Creditor agrees that each Creditor Party (as defined in the Security Agreement) shall be entitled to receive payment in full in cash of all Senior Debt Obligations owed to such Creditor Party (including all interest and expenses
accruing after the commencement of a proceeding under any Bankruptcy Law, whether or not constituting an allowed claim in such proceeding (“Post Petition Interest”)) before such Subordinated Creditor receives payment of any
Subordinated Debt. 
 (d) After the occurrence and during the continuance of any Default (including the commencement and
continuation of any Insolvency Proceeding relating to the Borrower or any Material Subsidiary), the Subordinated Creditor shall, if the Collateral Agent (acting at the direction of the Administrative Agent) so requests, collect, enforce and receive
payments on account of the Subordinated Debt as trustee for the Creditor Parties and deliver such payments to the Collateral Agent on account of the Senior Debt Obligations owed to the Creditor Parties (including all Post Petition Interest),
together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of the Borrower under the provisions of any other Financing Document. 
 (e) After the occurrence and during the continuance of any Default (including the commencement and continuation of any Insolvency Proceeding
against the Borrower or any Material Subsidiary), the Collateral Agent is authorized and empowered (but without any obligation to so do), in its discretion, (i) in the name of the Subordinated Creditor, to collect and enforce, and to submit
claims in respect of, Subordinated Debt and to apply any amounts received thereon to the Senior Debt Obligations (including any and all Post Petition Interest), and (ii) to require the Subordinated Creditor (A) to collect and enforce, and
to submit claims in respect of, Subordinated Debt and (B) to pay any amounts received on such obligations to the Collateral Agent for application to the Senior Debt Obligations (including any and all Post Petition Interest). 
 SECTION 2. Amendments, Etc. No amendment or waiver of any provision of this Agreement, and no consent to any departure by the
Subordinated Creditor or the Borrower herefrom, shall in any event be effective unless the same shall be in writing and signed by the Administrative Agent and then such waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. 
 SECTION 3. Addresses for Notices. All notices and other communications provided for
hereunder shall be in writing (including telecopier, telegraphic, telex or cable communication) and mailed, telecopied, telegraphed, telexed, cabled or delivered to it, if to the Subordinated Creditor, at
                                        ,

	AESC Credit Agreement	  	F-2	  	

 SECTION 4. No Waiver; Remedies. No failure on the part of the Administrative Agent or
any Creditor Party to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any
other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law. 
 SECTION 5.
Continuing Agreement; Assignments Under the Credit Agreement. This Agreement is a continuing agreement and shall (i) remain in full force and effect until the payment in full of the Senior Debt Obligations, (ii) be binding upon the
Subordinated Creditor, the Borrower and their respective successors and assigns, and (iii) inure to the benefit of, and be enforceable by, the Administrative Agent, the Lenders and their respective successors, transferees and assigns. Without

without limitation, all or any portion of its Commitment, the Advances and any Note to be held by it) to any Eligible Assignee, and such Eligible Assignee shall thereupon become vested with all the rights in respect thereof granted to such Lender
herein or otherwise, subject, however, to the provisions of Article VII (concerning the Administrative Agent) of the Credit Agreement. 
 SECTION 6. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

 REAL PROPERTY REQUIREMENTS 
 In order to secure further any increase in the outstanding principal amount of the Advances hereunder as a result of the Incremental
Commitments (the “Additional Debt”), the Borrower shall grant to the Collateral Agent a Lien on and security interest in any of the real property assets (other than Excluded Assets) of the Borrower that do not, in the opinion
of the Administrative Agent, secure the Additional Debt. In connection therewith, on or prior to the creation of the Additional Debt (and as a condition to the creation thereof), the Borrower shall deliver to the Administrative Agent: 
 (a) a schedule (the “Real Property Schedule”) clearly identifying the real properties with Fair
Market Values of at least $10,000,000 that at the time of the creation of the Additional Debt are either owned by Borrower or a Subsidiary or are reasonably likely to be acquired by the Borrower or a Subsidiary using the Additional Debt. The Real
Property Schedule shall include a list and description (including the street address, county or other relevant jurisdiction, state, record owner and book value thereof) of the aforementioned properties, and such other information as may be necessary

 AESC CREDIT AGREEMENT 
 FORM OF PNC CONTROL AGREEMENT 
 Deposit Account 
 

 
 Control Agreement 
 THIS DEPOSIT ACCOUNT CONTROL AGREEMENT (the “Agreement”) is made and entered into as of
[                    ], by and among PNC BANK, NATIONAL ASSOCIATION (“Bank”),
[                    ],
[                    ] and
[                    ] (each a “Debtor” and collectively, the “Debtors”), and CITIBANK, N.A.
(“Creditor”). 
 PREAMBLE 
 A. Bank has established one or more deposit accounts, numbered as set forth in Schedule I hereto, each in the name of a Debtor (each an “Account” and collectively, the
“Accounts”). 
 B. DEBTORS AND CREDITOR HAVE
ENTERED INTO CERTAIN AGREEMENTS WHEREBY DEBTORS HAVE GRANTED CREDITOR A FIRST
PRIORITY SECURITY INTEREST IN EACH OF THE ACCOUNTS. BANK IS NOT A
PARTY TO SUCH AGREEMENTS AND, AS TO BANK, ONLY TERMS SET FORTH
AND/OR DEFINED IN THIS AGREEMENT APPLY. 
 C. Creditor, Debtors and Bank are entering into this Agreement to perfect the security interest of Creditor in the Accounts. 
 TERMS 
 1. Accounts. All parties agree that each Account is a “deposit
account” within the meaning of Article 9 of the Uniform Commercial Code of the Commonwealth of Pennsylvania (“UCC”). Except as set forth in paragraph 13 hereof, Bank has not and will not agree with any third party to comply with
instructions or other directions concerning any Account or the disposition of funds in the Accounts originated by such third party without the prior written consent of Creditor and the applicable Debtor in whose name such account is established.

 2. Subordination of Security Interest; Fees. Bank hereby subordinates to Creditor all security interests,
encumbrances, claims and rights of setoff it may have, now or in the future, against the Accounts or any funds in the Accounts other than (i) in connection with the payment of Bank’s customary fees and charges pursuant to its agreement
with Debtor, as currently in effect and as modified by Bank from time to time, (ii) for the reversal of provisional credits, and (iii) as provided in paragraph 7. 
 3. Control of Accounts. Bank will comply with all instructions it receives from Creditor directing disposition of funds in the
Accounts without further consent of Debtors. Until Bank receives a Notice of Control from Creditor, as defined in paragraph 10 of this Agreement, Debtors also may

  

					
	AESC Credit Agreement	  	H-1	  	

 
withdraw funds and otherwise deal with the Accounts in the ordinary course of business, and Bank may honor all of Debtors’ instructions with respect to the Accounts without further consent
of Creditor. After Bank receives a Notice of Control from Creditor and has had a reasonable opportunity to comply therewith, neither any Debtor nor any other person or entity through or under any Debtor shall have any control over the use of, or any
right to withdraw any amount from, the Accounts, and Bank will thereafter comply only with instructions originated by Creditor directing disposition of funds in the Accounts without any consent of any Debtor. After receipt of a Notice of Control,
Bank shall have a reasonable time to institute instructions to all affected areas of the Bank to place a hold on further debits by any Debtor from the Accounts. If Notice of Control is received before 1:00 p.m. on a Business Day (as defined below),
Bank will freeze the Accounts effective with the close of banking business that day, but the Bank may honor all branch, ATM, point of sale, online and wire transfer activity that has been authorized or initiated prior to the time the freeze has been
placed. If Notice of Control is received by Bank after 1:00 p.m. on a Business Day, the freeze will be completed at the close of banking business on the next Business Day, and Bank will honor all branch, ATM, point of sale, online and wire transfer
activity that has been authorized or initiated prior to the time the freeze has been placed. Nothing in this paragraph 3 shall require Bank to comply with instructions from Creditor which are unduly burdensome on Bank, in Bank’s reasonable
determination. As used in this Agreement, the term “Business Day” means any day other than a Saturday, Sunday or public holiday under the laws of the state(s) indicated in paragraph 10(b) hereof as Bank’s addresses. 
 4. Limitation of Liability of Bank. Bank shall have no responsibility or liability to Creditor for complying with instructions
concerning the Accounts from any Debtors or any Debtor’s authorized representatives which are received by Bank before Bank receives a Notice of Control and has had reasonable opportunity to comply with it as set forth in paragraph 3 above. Bank
shall have no responsibility or liability to Debtors for complying with a Notice of Control or complying with instructions concerning the Accounts originated by Creditor, and shall have no responsibility to investigate the appropriateness of any
such instruction or Notice of Control, even if any Debtor notifies Bank that Creditor is not legally entitled to originate any such instruction or Notice of Control. 
 5. Customer Agreement. In the event of a conflict between this Agreement and any other agreement between Bank and any Debtor, the terms of this Agreement will prevail. 
 6. Statements. Bank shall provide Creditor with duplicate copies of the regular monthly bank statements provided to Debtors with
respect to the Accounts. Any applicable fees therefor shall be charged to the Accounts. 
 7. Uncollected Funds. If any
receipts deposited in any Account are returned unpaid or otherwise dishonored, Bank shall have the right to charge any and all such returned or dishonored items against any Account or to demand reimbursement therefor directly from any Debtor. If
there are insufficient collected funds in the Accounts or Debtors fail to so repay Bank, Creditor shall repay Bank for such debit or items immediately upon demand to the extent that Creditor is then in possession of the proceeds of the check or
other deposit or credit to which the debit relates. 
 8. Exculpation of Bank; Indemnification by Debtors. Debtors and
Creditor agree that Bank shall have no liability to any of them for any loss or damage that any of them may claim to have suffered or incurred, either directly or indirectly, by reason of this Agreement or any transaction or service contemplated by
the provisions hereof, except to the extent primarily attributable to the gross negligence or willful misconduct of Bank, as determined by a final non-appealable judgment by a court of competent jurisdiction. In no event shall Bank be liable for
losses or delays resulting from computer malfunction, interruption of communication facilities, labor difficulties or other causes beyond Bank’s reasonable control. Debtors jointly and severally agree to indemnify and hold harmless Bank, its
affiliates, and its

  

					
	AESC Credit Agreement	  	H-2	  	

 
and their directors, officers, agents and employees from and against any and all claims, damages, penalties, judgments, liabilities, losses or expenses (including reasonable attorney’s fees
and disbursements) arising out of, resulting from, or in any way related to this Agreement or any action taken or not taken pursuant to this Agreement except to the extent such claims, damages, penalties, judgments, liabilities, losses or expenses
are primarily caused by Bank’s gross negligence or willful misconduct, as determined by a final non-appealable judgment by a court of competent jurisdiction. Bank’s duties and obligations shall be determined solely by the provisions of
this Agreement and Bank shall not be liable except for the performance of its duties and obligations as are set forth herein. Bank shall have no obligation to review or confirm that any actions taken pursuant to this Agreement comply with any other
agreement or document. Substantial compliance by Bank with its standard procedures for the services Bank is providing hereunder shall be deemed to be exercise by it of ordinary care. In no event shall Bank be liable for any lost profits or for any
indirect, special, consequential or punitive damages even if advised of the possibility or likelihood of such damages. This paragraph shall survive termination of this Agreement. 
 9. Termination. This Agreement may be terminated by Debtors only upon delivery to Bank of a written notification thereof jointly
executed by Debtors and Creditor. This Agreement may be terminated by Creditor or by Bank at any time, with or without cause, upon delivery of written notice thereof to each other party. Creditor shall give timely written notice to Bank that this
Agreement, or its security interest in any Account, is terminated. Upon receipt of such written notice by Bank, the obligations of Bank hereunder with respect to the operation and maintenance of such Account shall terminate, Creditor shall have no
further right to originate instructions concerning such Account and any previous Notice of Control delivered by Creditor shall be deemed to be of no further force and effect. Notwithstanding anything else to the contrary herein, Bank may terminate
this Agreement immediately upon written notice to the other parties in the event of suspected fraud, or other illegal activity, or for any reason, as determined in the Bank’s sole discretion, that requires immediate closing of the Accounts.

 10. Notices. 
 (a) Notice of Control to Bank. A “Notice of Control” to Bank from Creditor shall be given only upon the occurrence of a default or under other circumstances set forth in any agreement
between Creditor and Debtor and shall consist of the following three steps. Notice of Control shall not be, or be deemed to have been, given until all three of the following steps are completed: 
 (i) Creditor shall place a telephone call to Bank at 1-866-295-9060 to notify Bank that Creditor will be faxing a Notice of

Control to Bank pursuant to this Agreement, is Bank under any obligation to provide information to Creditor regarding any other accounts or activity of Debtors that are not the subject of this Agreement unless such other accounts or activity are
subject to a separate agreement among Bank, the relevant Debtors and Creditor.

disposition of the funds in such Account, or (ii) commence, at Debtors’ expense, an interpleader action in any competent federal or state court located in the Commonwealth of Pennsylvania, and otherwise to take no further action except in
accordance with joint written instructions from Debtors and Creditor or in accordance with the final order of a competent court, served on Bank. 
 14. Miscellaneous.
