 (d) This Amendment has been duly
executed and delivered by it. This Amendment is its legal, valid and binding obligations, enforceable against it in accordance with its terms, except to the extent limited by any applicable bankruptcy, insolvency, reorganization, moratorium or

 (b) The Credit Agreement, as specifically amended by this Amendment, and each of the other Financing Document, is and shall continue to be
in full force and effect and is hereby in all respects ratified and confirmed. 
 (c) The execution, delivery and effectiveness
of this Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of any Lender Party or the Administrative Agent under any of the Financing Documents, nor constitute a waiver of any provision of any
of the Financing Documents.

Administrative Agent notifies the Borrower that the Required Lenders wish to amend Section 5.03 for such purpose), then the Borrower’s compliance with such covenant shall be determined on the basis of generally accepted accounting
principles in effect immediately before the relevant change in generally accepted accounting principles became effective, until either such notice is withdrawn or such covenant is amended in a manner satisfactory to the Borrower and the Required
Lenders. 
 (c) Letter of Credit. Unless otherwise specified, all references herein to the amount of a Letter of Credit at any
time shall be deemed to mean the stated face amount of such Letter of Credit in effect at such time; provided, however, that with respect to any Letter of Credit that, by its terms or the terms of any Issuer Document related thereto,
provides for one or more automatic increases in the stated amount thereof, the amount of such Letter of Credit shall be deemed the maximum stated amount of such Letter of Credit after giving effect to all increases thereof, whether or not such
maximum face amount is in effect at such time.

 SECTION 10. 
 AMOUNTS AND TERMS OF THE ADVANCES 
 AND LETTERS OF CREDIT 

(a) The Advances. (a) Revolving Advance . Each Revolving Lender severally agrees, on the terms and conditions hereinafter set
forth, to make advances (each a “Revolving Advance”) in Dollars to the Borrower from time to time on any Business Day during the period from the Closing Date until the Final Maturity Date in an amount for each such Revolving
Advance not to exceed such Revolving Lender’s Unused Commitment at such time; provided that after giving effect to any Revolving Borrowing, (i) the Total Revolving Outstandings shall not exceed the Revolving Facility, and
(ii) the aggregate Outstanding Amount of the Revolving Advances of any Revolving Lender plus such Revolving Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations plus such Revolving Lender’s Pro Rata
Share of the Outstanding Amount of all Swing Line Advances made by the Swing Line Bank shall not exceed such Revolving Lender’s Revolving Commitment. Each Revolving Borrowing shall be in an aggregate amount of $2,000,000 or an integral multiple
of $1,000,000 in excess thereof (other than a Revolving Borrowing the proceeds of which shall be used solely to repay or prepay in full any Swing Line Advances made by the Swing Line Bank or any L/C Borrowing) and shall consist of Revolving Advances
of the same Type made simultaneously by the Revolving Lenders ratably according to their Revolving Commitments. Within the limits of each Revolving Lender’s Unused Commitment in effect from time to time, the Borrower may borrow under this
Section 2.01(a), prepay pursuant to Section 2.06(a) and reborrow under this Section 2.01(a). 
 (b) Term Advance.
Each Term Lender severally agrees, on the terms and conditions hereinafter set forth, to make a single advance to the Borrower on any one Business Day during the period from the Closing Date until the Term Commitment Termination Date in an amount
not to exceed such Term Lender’s Term Commitment. The Term Borrowing shall consist of Term Advances of the same Type made simultaneously by the Term Lenders on such Business Day ratably according to their Term Commitments. Amounts borrowed
under this Section 2.01(b) and repaid or prepaid may not be reborrowed. 
 (c) Swing Line Advance. The Borrower may request
the Swing Line Bank to make, and the Swing Line Bank agrees to make, on the terms and conditions hereinafter set forth, Swing Line Advances to the Borrower from time to time on any Business Day during the period from the Closing Date until the Final
Maturity Date (i) in an aggregate amount not to exceed at any time outstanding $10,000,000 (the “Swing Line Facility”) and (ii) in an amount for each such Swing Line Borrowing not to exceed the aggregate of the
Unused Commitments of the Revolving Lenders at such time. No Swing Line Advance shall be used for the purpose of funding the payment of principal of any other Swing Line Advance. Each Swing Line Borrowing shall be in an amount of $500,000 or an
integral multiple of $100,000 in excess thereof and shall be made as a Base Rate Advance. Within the limits of the Swing Line Facility and within the limits referred to in clause (ii) above, the Borrower may borrow under this
Section 2.01(c), repay pursuant to Section 2.04 or prepay pursuant to Section 2.06(a) and reborrow under this Section 2.01(c). 
  

					
		 	36	  	AESC Amended and Restated Credit Agreement

 (d) Letters of Credit. Subject to the terms and conditions set forth herein, (i) each
Issuing Bank agrees, in reliance upon the agreements of the other Revolving Lenders set forth in Section 2.03, (A) from time to time on any Business Day during the period from the Closing Date until the Letter of Credit Expiration Date, to
make L/C Credit Extensions for the account of the Borrower or its Subsidiaries, and to amend or extend Letters of Credit previously issued by it, in accordance with Section 2.03(a)(i) and (ii), and (B) to honor drawings under the Letters
of Credit issued by it; and (ii) the Revolving Lenders severally agree to participate in Letters of Credit issued for the account of the Borrower or its Subsidiaries and any L/C Borrowings thereunder; provided that after giving effect to
any L/C Credit Extension with respect to any Letter of Credit, (x) the Total Revolving Outstandings shall not exceed the Revolving Facility and (y) the aggregate Outstanding Amount of the Revolving Advances of any Revolving Lender, plus
such Revolving Lender’s Pro Rata Share of the Outstanding Amount of all L/C Obligations, shall not exceed such Revolving Lender’s Revolving Commitment. Each request by the Borrower for the issuance of, or an amendment to increase the
amount of, any Letter of Credit shall be deemed to be a representation by the Borrower that the L/C Credit Extension so requested complies with the conditions set forth in the proviso to the preceding sentence. Within the foregoing limits, and
subject to the terms and conditions hereof, the Borrower’s ability to obtain Letters of Credit shall be fully revolving, and accordingly the Borrower may, during the foregoing period, obtain Letters of Credit to replace Letters of Credit that
have expired or that have been drawn upon and reimbursed. 
 (e) Letters of Credit Generally. (i) No Issuing Bank shall
issue any Letter of Credit if the expiry date of such requested Letter of Credit would occur after the Letter of Credit Expiration Date, unless all the Revolving Lenders have approved such expiry date; provided that in no event shall the
expiry date of any requested Letter of Credit occur on or after the Business Day next preceding the fifth anniversary of the Closing Date. 
 (b) No Issuing Bank shall be under any Obligation to make any L/C Credit Extension if: 
 (i) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain such Issuing Bank from issuing such Letter of Credit, or any Applicable Law
to such Issuing Bank or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such Issuing Bank shall prohibit, or request that the Issuing Bank refrain from, the issuance of Letters
of Credit generally or such Letter of Credit in particular or shall impose upon such Issuing Bank with respect to such Letter of Credit any restriction, reserve or capital requirement (for which such Issuing Bank is not otherwise compensated
hereunder) not in effect on the Closing Date, or shall impose upon such Issuing Bank any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which such Issuing Bank in good faith deems material to it; 
 (ii) the making of such L/C Credit Extension would violate any Applicable Laws; 
  

					
		 	37	  	AESC Amended and Restated Credit Agreement

 (iii) 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; 
 (iv) such L/C Credit
Extension is to be denominated in a currency other than Dollars; 
 (v) such L/C Credit Extension contains any
provisions for automatic reinstatement of the stated amount after any L/C Borrowing thereunder; or 
 (vi) a
default of any Revolving Lender’s obligations to fund under Section 2.03 exists or any Lender is then a Defaulting Lender, unless such Issuing Bank has entered into satisfactory arrangements with the Borrower or such Revolving Lender to
eliminate such Issuing Bank’s risk with respect to such Revolving Lender. 
 (c) 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. 
 (d) 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. 
 (b) Making the Advances. (i) 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 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

  

					
		 	38	  	AESC Amended and Restated Credit Agreement

 
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. 
 (ii) 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. 
 (iii) 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 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

  

					
		 	39	  	AESC Amended and Restated Credit Agreement

 
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. 
 (iv) 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 (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or redeployment of deposits or other
funds acquired by such Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date. 
 (v) 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. 
 (vi) 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. 
 (c) 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. (a) Each Letter of Credit

  

					
		 	40	  	AESC Amended and Restated Credit Agreement

 
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. 
 (b) 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 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. 
 (c) 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

  

					
		 	41	  	AESC Amended and Restated Credit Agreement

 
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. 
 (d) 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. (a) 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 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. 
 (b) 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

  

					
		 	42	  	AESC Amended and Restated Credit Agreement

 
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. 
 (c) 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. 
 (d) 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. 
 (e) 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 irrevocable, 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. 
 (f) 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. 
  

					
		 	43	  	AESC Amended and Restated Credit Agreement

 (c) Repayment of Participations. (a) 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. 
 (b) 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 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

  

					
		 	44	  	AESC Amended and Restated Credit Agreement

 
any notice or information to the contrary, and such Issuing Bank shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or
assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason. 
 (e) Cash Collateral. (i) Upon the occurrence and during the continuance of any Event of Default, at the request of the Administrative Agent, (A) if an Issuing Bank has honored any full or
partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing, or (B) if, as of the Letter of Credit Expiration Date (or, if the expiry date of such Letter of Credit is after the Letter of Credit
Expiration Date (as may be agreed by the 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). 
 (ii) At the
request of the Administrative Agent (the Administrative Agent hereby agreeing to make such request upon a request from any Issuing Bank), if (A) there is at any time a Defaulting Lender, and (B) (I) one or more Letters of Credit are
then outstanding or (II) an Issuing Bank has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Borrowing that is then outstanding, then, in any such case, the Borrower shall immediately
(x) repay to each Issuing Bank such Defaulting Lender’s Pro Rata Share of such L/C Borrowing, together with accrued interest thereon through the date of such repayment and (y) Cash Collateralize such Defaulting Lender’s Pro Rata
Share of the aggregate undrawn amount of all outstanding Letters of Credit. 
 (iii) The Borrower hereby grants
to the Administrative Agent, for the benefit of each Issuing Bank and the 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

		 	45	  	AESC Amended and Restated Credit Agreement

 
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

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: 
 (a) any lack of validity or enforceability of such Letter of Credit, this Agreement
or any other Financing Document; 
 (b) 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; 
 (c) 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;

 (d) 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 
 (e) 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

  

					
		 	46	  	AESC Amended and Restated Credit Agreement

 
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.

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.

issued by such Issuing Bank, and upon such payments, the obligations of such Lender hereunder with respect to such unused Commitments which have been terminated shall, by the provisions hereof, be released and discharged; provided, however,
that such Lender’s rights and obligations provided in Section 8.16 with respect to such unused Commitments which have been terminated shall survive such release and discharge as to matters occurring prior to such date. 
 (f) Prepayments. (a) Optional. The Borrower may, upon at least one Business Day’s notice in the case of Base Rate Advances
and three Business Days’ notice in the case of Eurodollar Rate Advances, in each case to the Administrative Agent stating the proposed date and aggregate principal amount of the prepayment, and if the notice is given the Borrower shall, prepay

 (i) Base Rate Advances. During such periods as such Advance is a Base Rate Advance, a rate per annum equal at all

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 Rata Share of the average daily outstanding Swing Line Advances made by the Swing Line Bank during such fiscal quarter.

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

 (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 of the L/C Obligations to be agreed between the Borrower and the applicable Issuing Bank (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.

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

  

					
		 	50	  	AESC Amended and Restated Credit Agreement

 
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. 
 (ii) 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. 
 (iii) The Borrower hereby authorizes each Lender
Party and each of its Affiliates, if and to the extent payment owed to such Lender Party by the Borrower is not made when due hereunder or, in the case of a Lender, under its Note or Notes, to charge from time to time, to the fullest extent
permitted by law, against any or all of the Borrower’s accounts with such Lender Party or such Affiliate any amount so due. 
 (iv) 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. 
 (v) 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. 
 (vi) 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

  

					
		 	51	  	AESC Amended and Restated Credit Agreement

 
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. 
 (vii) 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. 
 (viii) 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

  

					
		 	52	  	AESC Amended and Restated Credit Agreement

 
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. 
 (j) Illegality. Notwithstanding
any other provision of this Agreement, if the introduction of or any change in or in the interpretation of any law or regulation shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any
Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Advances hereunder, then, on notice thereof and demand therefor by such Lender to the
Borrower through the Administrative Agent, (i) each Eurodollar Rate Advance will automatically, upon such demand, Convert into a Base Rate Advance and (ii) the obligation of such Lender to make, or to Convert Advances into, Eurodollar Rate
Advances shall be suspended until the Administrative Agent shall notify the Borrower that such Lender has determined that the circumstances causing such suspension no longer exist; provided that, before making any such demand, such Lender
agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Lender or its Eurodollar Lending
Office to continue to perform its obligations to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Advances and would not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. 
 (k) Interest Elections. (a) Optional. (a) 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. 
 (b) 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

  

					
		 	53	  	AESC Amended and Restated Credit Agreement

 
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. 
 (c) 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. 
 (d) 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. (a) 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. 
 (b) 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. 
 (c) 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. 
 (l) Increased Costs, Etc. (i) 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

  

					
		 	54	  	AESC Amended and Restated Credit Agreement

 
Eurodollar Rate Advances or of agreeing to maintain or participate in the L/C Credit Extensions or of agreeing to make or of making or funding or maintaining L/C Credit Extensions (excluding, for
purposes of this Section 2.12, any such increased costs resulting from (A) Taxes or Other Taxes (as to which Section 2.13 shall govern) and (B) changes in the basis of taxation of overall net income or overall gross income by the
United States or by the foreign jurisdiction or state under the laws of which such Lender Party is organized or has its Applicable Lending Office or any political subdivision thereof), then the Borrower shall from time to time, upon demand by such
Lender Party (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender Party additional amounts sufficient to compensate such Lender Party for such increased cost; provided,
however, that a Lender Party claiming additional amounts under this Section 2.12(a) agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Applicable Lending
Office if the making of such a designation would avoid the need for, or reduce the amount of, such increased cost that may thereafter accrue and would not, in the reasonable judgment of such Lender Party, be otherwise disadvantageous to such Lender
Party. A certificate as to the amount of such increased cost, submitted to the Borrower by such Lender Party, shall be conclusive and binding for all purposes, absent manifest error. 
 (ii) 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. 
 (iii)
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.

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

 (iv) As soon as practicable (but in no event later than 90 days) after the date of any
payment of Covered Taxes, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment. Excluding payments made by the Administrative
Agent, in the case of any payment hereunder or under the Notes by or on behalf of the Borrower through an account or branch outside the United States or by or on behalf of the Borrower by a payor that is not a United States person, if the Borrower
determines that no Covered Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Administrative Agent, at such address, an opinion of counsel acceptable to the Administrative Agent stating
that such payment is exempt from Covered Taxes. For purposes of subsections (d) and (e) of this Section 2.13, the terms “United States” and “United States person” shall have the meanings
specified in Section 7701 of the Code. 
 (v) 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

  

					
		 	57	  	AESC Amended and Restated Credit Agreement

 
withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Covered Taxes unless and until such Lender Party provides the appropriate forms certifying
that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Covered Taxes for periods governed by such forms; provided, however, that if, at the effective date of the Assignment and
Acceptance pursuant to which a Lender Party becomes a party to this Agreement, the Lender Party assignor was entitled to payments under subsection (a) of this Section 2.13 in respect of United States withholding tax with respect to
interest paid at such date, then, to such extent, the term “Covered Taxes” shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Covered Taxes) United States
withholding tax, if any, applicable with respect to the Lender Party assignee on such date. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to compute the tax
payable and information required by the applicable Internal Revenue Service form (or related certificate described above), that the applicable Lender Party reasonably considers to be confidential, such Lender Party shall give notice thereof to the
Borrower and shall not be obligated to include in such form or document such confidential information. 
 (vi) 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. 
 (vii) 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. 
 (viii) 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. 
 (n) Evidence of Debt. (i) Each Lender Party shall
maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the

  

					
		 	58	  	AESC Amended and Restated Credit Agreement

 
Borrower to such Lender Party resulting from the Advances or L/C Credit Extensions and/or L/C Borrowings owing to such Lender Party from time to time, including the amounts of principal and
interest payable and paid to such Lender Party from time to time hereunder. The Borrower agrees that upon notice by any Lender Party to the Borrower (with a copy of such notice to the Administrative Agent) to the effect that a promissory note or
other evidence of indebtedness is required or appropriate in order for such Lender Party to evidence (whether for purposes of enforcement or otherwise) the Advances or L/C Borrowings owing to, or to be made by, such Lender Party, the Borrower shall
promptly execute and deliver to such Lender Party, with a copy to the Administrative Agent, a Note, in substantially the form of Exhibit A-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. 
 (ii) 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.

 (iii) 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. 
 (o) 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 to make cash dividends from time to time to the Parent and (c) in the case of any additional borrowing made pursuant to Section 2.16, for
general corporate purposes. 
 (p) Request for Commitments. (i) Provided there exists no Default, upon notice to the
Administrative Agent (which shall promptly notify the Lenders), the

  

					
		 	59	  	AESC Amended and Restated Credit Agreement

 
Borrower may, from time to time, request from the Lenders commitments to make new loans (to 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. 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. 
 (ii) 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 covenant 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), and (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. 
 (iii) 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

  

					
		 	60	  	AESC Amended and Restated Credit Agreement

 
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. 
 (iv) 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. 
 (v) 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. 
 (vi) 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.

Agent shall not be responsible to any Lender Party for the due 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

notice, consent, certificate or other instrument or writing (which may be by telegram, telecopy or telex) reasonably believed by it to be genuine and signed or sent by the proper party or parties.

any other Lender and may exercise the same as though it were not the Administrative Agent or an Arranger Party, as applicable; and the terms “Lender”, “Lenders”, “Revolving Lender”,
“Revolving Lenders”, “Swing Line Bank”, “Term Lender” or “Term Lenders” shall, unless otherwise expressly indicated, include each of CUSA, CGMI, Citibank, Scotia Capital, BAS, and

from and generally engage in any kind of business with, the Borrower, any Subsidiary of the Borrower and any Person that may do business with or own securities of the Borrower or any such Subsidiary, all as if CUSA, CGMI, Citibank, Scotia Capital,
BAS, and BofA, were not the Administrative Agent or an Arranger Party, as applicable, and without any duty to account therefor to the Lender Parties. 
 (d) Lender Party Credit Decision. Each Lender Party acknowledges that it has, independently and without reliance upon any Agent, any Arranger Party or any other Lender Party, and based on the financial
statements referred to in Sections 3.01 and 5.04 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Financing Documents to which it is a
party. Each Lender Party also acknowledges that it will, independently and without reliance upon any Agent, any Arranger Party or any other Lender Party and based on such documents and information as it shall deem appropriate at the time, continue
to make its own credit decisions in taking or not taking action under this Agreement and the other Financing Documents to which it is a party.

 (e) Indemnification. (i) Each Lender severally agrees to indemnify the Administrative

penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent or any Arranger Party, as the case may be, in any way relating
to or arising out of the Financing Documents or any action taken or omitted by the Administrative Agent or any Arranger Party under the Financing Documents (collectively, the “Indemnified Costs”); provided that no
Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting directly and primarily from the Administrative Agent’s 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 Pro Rata 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. 
 (ii) Each Revolving Lender severally agrees to indemnify each Issuing Bank (to the
extent not promptly reimbursed by the Borrower without limiting its obligation to do so) from and against such Revolving Lender’s Pro Rata Share of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against such Issuing Bank in its capacity as such in any way relating to or arising out of the Financing Documents or any action taken

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

  

					
		 	84	  	AESC Amended and Restated Credit Agreement

 
no Lender Party shall be responsible for the failure of any other Lender Party to reimburse the Administrative Agent, any Arranger Party or any Issuing Bank, as the case may be, for such other
Lender Party’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender Party hereunder, the agreement and obligations of each Lender Party contained in this Section 7.05 shall survive the
payment in full of principal, interest and all other amounts payable hereunder and under the other Financing Documents. 
 (f)
Successor Administrative Agent. The Administrative Agent may resign at any time by 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. 
 (g) Liability. Neither the Administrative 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. 
 (h) Compensation of the
Administrative Agent. 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 or any political subdivision or taxing authority thereof. Except as

  

					
		 	85	  	AESC Amended and Restated Credit Agreement

 
otherwise expressly provided herein, no Lender Party shall have any liability for any fees, expenses or disbursements of the Administrative Agent. Upon its resignation or removal, the
Administrative Agent shall be entitled to the prompt payment by the Borrower of its compensation and indemnification for the services rendered under this Agreement and the other Financing Documents to which it is a party and to reimbursement of all
reasonable out-of-pocket expenses up to the date of resignation or removal (including the reasonable fees and expenses of counsel, if any) incurred in connection with the performance of such services. The agreements in this Section 7.08 shall
survive any resignation or removal of the Administrative Agent and the termination of the other provisions of this Agreement. 
 (i) Exculpatory Provisions. The Administrative Agent makes no representation as to the title of the Borrower or as to the rights and interests granted or the security afforded by this Agreement or any other Financing Document, or as to the
validity, execution (except by itself), enforceability, legality or sufficiency of this Agreement, any other Financing Document, and the Administrative Agent (in its individual and agency capacities) shall not incur any liability or responsibility
in respect of any such matters. 
 (j) Treatment of Lenders. The Administrative Agent 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 the Administrative Agent shall receive notice to the contrary from such Lender Party.

 (k) Miscellaneous. (a) Instructions. The Administrative Agent shall have the right at any time to seek
instructions concerning the administration of its duties and obligations hereunder or under any other Financing Documents from the Lenders or any court of competent jurisdiction. In the event there is any disagreement between the parties to this

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. 
 (viii) Notwithstanding anything in this Agreement to the contrary (including any other provision regarding assignments, participations, transfers or novations), any Lender (a “Granting Lender”) may, without the
consent of any other party hereto, grant to a special purpose vehicle (whether a corporation, partnership, limited liability company, trust or otherwise, an “SPV”) sponsored or managed by the Granting Lender or any Affiliate
thereof, a participation in all or any part of any Advance (including the Commitment therefor) that such Granting Lender has made or will make pursuant to this Agreement; provided that (i) such Granting Lender’s obligations under
this Agreement (including its Commitment) shall remain unchanged; (ii) such Granting Lender shall remain the holder of its Note for all purposes under this Agreement; and (iii) the Borrower, the Administrative Agent and the other Lenders

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. 
 (ix) 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

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. 
 (h) Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different

sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any of the other Financing Documents to which it is a party, or for recognition or enforcement of any
judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the fullest extent permitted by
law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.
Nothing in this Agreement shall affect any right that any party may otherwise have to bring any action or proceeding relating to this Agreement or any of the other Financing Documents in the courts of any jurisdiction. 
 (ii) 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. 
 (j) Governing Law. This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

Lender Party may, without the prior written consent of the Borrower, disclose to any Person (i) any confidential, proprietary or non-public information of the Borrower furnished to the Administrative Agent, the Arranger Parties or the Lender
Parties by the Borrower (such information being referred to collectively herein as the “Confidential Information”) or (ii) the fact that the Confidential Information has been made available or any of the terms,
conditions or other facts with respect to the Confidential Information, in each case except as permitted by Section 8.07 or this Section 8.12 and except that the Administrative Agent, each of the Arranger Parties and each of the Lender
Parties may disclose Confidential Information (i) to its and its Affiliates’ employees, officers, directors, agents, sub-agents and 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

any credit insurance provider relating to the Borrower and its Obligations), so long as the Persons to whom such disclosure is made will be informed of the confidential nature of such Confidential Information and such Persons have agreed in writing
(or with respect to any rating agency, in writing or otherwise) to keep such Confidential Information confidential on substantially the same terms as provided herein, (vii) to the extent such Confidential Information (A) is or becomes
generally available to the public on a non-confidential basis other than as a result of a breach of this Section 8.12 by the Administrative Agent, such Arranger Party or such Lender Party, or (B) is or becomes available to the
Administrative Agent, such Arranger Party or such Lender Party on a nonconfidential basis from a source other than a Borrower and (viii) with the consent of the Borrower. 
 (ii) 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. 
  

					
		 	98	  	AESC Amended and Restated Credit Agreement

 (iii) 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. 
 (iv) 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.

 (v) 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. 
 (vi) 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). 

(vii) 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. 
 (m) 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). 
 (n) 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. 
 (o) Limitations. (i) 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. 
  

					
		 	99	  	AESC Amended and Restated Credit Agreement

 (ii) 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. 
 (p) 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. 
 (q) USA Patriot Act Notice.
Each of the Lender Parties and the Administrative Agent (for itself and not on behalf of any Lender Party) hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law
October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other
information that will allow such Lender Party or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Act. 
 SECTION 8.18. No Fiduciary Duty. Each Agent, each Lender and their Affiliates (collectively, solely for purposes of this paragraph, the “Lenders”), may have economic interests that
conflict with those of the Borrower, its stockholders and/or its affiliates. The parties hereto acknowledge and agree that (i) the transactions contemplated by the credit documents (including the exercise of rights and remedies hereunder and
thereunder) are arm’s-length commercial transactions between the Lenders, on the one hand, and the Borrower, on the other, and (ii) in connection therewith and with the process leading thereto, (x) no Lender has assumed an advisory or
fiduciary responsibility in favor of the Borrower, its stockholders or its affiliates with respect to the transactions contemplated hereby (or the exercise of rights or remedies with respect thereto) or the process leading thereto (irrespective of
whether any Lender has advised, is currently advising or will advise the Borrower, its stockholders or its Affiliates on other matters) or any other obligation to the Borrower except the obligations expressly set forth in the credit documents and
(y) each Lender is acting solely as principal and not as the agent or fiduciary of the Borrower, its management, stockholders, creditors or any other Person. The Borrower acknowledges and agrees that the Borrower has consulted its own legal and
financial advisors to the extent it deemed appropriate and that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto.

 FOR VALUE RECEIVED, the undersigned, ALLEGHENY ENERGY SUPPLY COMPANY, LLC, a Delaware

 The Borrower promises to pay interest on the unpaid

 Both principal and interest are payable in lawful money of the United States of America to Citicorp USA, Inc., as Administrative Agent, at

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

 Reference is made 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

financial institutions referred to therein as Initial Lenders, Swing Line Bank and Initial Issuing Bank, and Citicorp USA, Inc., as Administrative Agent. 
 [                    ] (the “Assignor”) and
[                    ] (the “Assignee”) each agrees severally with respect to all information relating to it and its
assignment hereunder and on Schedule 1 hereto as follows: 
 The Assignor hereby sells and assigns, without recourse except
as to the representations and warranties made by it herein, to the Assignee, and the Assignee hereby purchases and assumes from the Assignor, an interest in and to the Assignor’s rights and obligations under the Credit Agreement as of the date
hereof equal to the percentage interest specified on Schedule 1 hereto of all outstanding rights and obligations under the Credit Agreement [and, if the Assignor is an Issuing Bank, all of the Assignor’s rights and obligations under the Credit
Agreement as an Issuing Bank]. After giving effect to such sale and assignment, the Assignee’s [Revolving] [Term] Commitment and the amount of the [Revolving] [Term] Advances owing to the Assignee will be as set forth on Schedule 1 hereto.

 The Assignor (i) represents and warrants that it is the legal and beneficial owner of the interest or interests being
assigned by it hereunder and that such interest or interests are free and clear of any adverse claim; (ii) makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in

	1	This form is to be used for the assignment of either Revolving Commitments/Revolving Advances or Term Commitments/Term Advances. If the assigning Lender holds both
Revolving Commitments/Revolving Advances and Term Commitments/Term Advances, a separate Assignment and Acceptance will be executed for each assignment.

 The Assignee
(i) confirms that it has received a copy of the Credit Agreement and each of the other Financing Documents, together with copies of the financial statements referred to in Sections 3.01 and 5.04 of the Credit Agreement and such other
documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into this Assignment and Acceptance; (ii) agrees that it will, independently and without reliance upon the Administrative Agent, the
Assignor or any other Lender, or Arranger Party and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Credit Agreement or any other
Financing Document; (iii) confirms that it is an Eligible Assignee; (iv) appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under the Financing Documents
as are delegated to the Administrative Agent, respectively, by the terms thereof, together with such powers and discretion as are reasonably incidental thereto; (v) agrees that it will perform in accordance with their terms all of the
obligations that by the terms of the Financing Documents are required to be performed by it as a Lender; and (vii) attaches any U.S. Internal Revenue Service forms required under Section 2.13 of the Credit Agreement.

 Upon such acceptance and recording by the Administrative Agent, as of the Effective Date, (i) the Assignee shall be a
party to the Credit Agreement and, to the extent provided in this Assignment and Acceptance, have the rights and obligations of a Lender thereunder and (ii) the Assignor shall, to the extent provided in this Assignment and Acceptance,
relinquish its rights and be released from its obligations under the Financing Documents (other than its rights and obligations under the Financing Documents that are specified under the terms of such Financing Documents to survive the payment in
full of the Obligations of the Borrower under the Financing Documents to the extent any claim thereunder relates to an event arising prior to the Effective Date of this Assignment and Acceptance) and, if this Assignment and Acceptance covers all of
the remaining portion of the rights and obligations of the Assignor under the Credit Agreement, the Assignor shall cease to be a party thereto. 
 Upon such acceptance and recording by the Administrative Agent, from and after the Effective Date, the Administrative Agent shall make all payments under the Credit Agreement and the Notes (if any) in
respect of the interest assigned hereby (including all payments of principal, interest and commitment fees with respect thereto) to the Assignee. The Assignor and the Assignee shall make all appropriate adjustments in payments under the Credit

 (iv) No Issuing Bank shall be under
the obligation to amend any Letter of Credit if (A) such Issuing Bank would have no obligation at such time to issue such Letter of Credit in its amended form under the terms hereof, or (B) the beneficiary of such Letter of Credit does not
accept the proposed amendment to such Letter of Credit. 
 SECTION 2.02. Making the Advances. (a) Except as
otherwise provided in Section 2.03, each Borrowing to any Borrower shall be made on notice, given by AYE on behalf of such Borrower (and each Borrower other than AYE hereby unconditionally and irrevocably instructs AYE to issue such notice on
its behalf) not later than 2:00 p.m. (New York City time) on the third Business Day prior to the date of the proposed Borrowing in the case of a Borrowing consisting of Eurodollar Rate Advances, or on the date of the proposed Borrowing in the case
of a Borrowing consisting of Base Rate Advances, to the Administrative Agent, which shall give to each Lender prompt notice thereof by telecopier or electronic mail. Each such notice of a Borrowing (a “Notice of Borrowing”)
shall be by telephone, confirmed immediately in writing, or telecopier or electronic mail, in substantially the form of Exhibit B, specifying therein (i) the identity of the Borrower and (ii) the requested (A) date of such Borrowing,
(B) Type of Advances comprising such Borrowing, (C) aggregate amount of such Borrowing and (D) 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 
  

					
	AYE Refinancing Credit Agreement	  	41	  	

 
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
(i) with respect to the Initial Borrowing, directly apply (x) the Revolving Advances, together with the Term Advances, to the repayment of the Existing AYE Debt and (y) the L/C Credit Extensions for the account of AYE to the
continuance of the Existing L/Cs as AYE Letters of Credit, (ii) with the respect to the single Term Borrowing, directly apply the Term Advances, together with Revolving Advances made as part of the Initial Borrowing, to the repayment of the
Existing AYE Debt and (iii) with respect to subsequent Revolving Borrowings, make such funds available to the relevant Borrower, by crediting such Borrower’s Borrowing Account. 
 (b) Anything in subsection (a) above to the contrary notwithstanding, (i) no Borrower may 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 2.10 or 2.11 and (ii) the Advances may not be
outstanding as part of more than fifteen separate Borrowings. 
 (c) Each Notice of Borrowing shall be irrevocable and binding
on the Borrower issuing such Notice of Borrowing. In the case of any Borrowing that the relevant Borrower has specified in the related Notice of Borrowing is to be comprised of Eurodollar Rate Advances, such 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. 
 (d) 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 relevant 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 such 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 such Borrower until the date such amount is repaid or paid to the Administrative Agent, at (i) in the case of such
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. 
  

					
	AYE Refinancing Credit Agreement	  	42	  	

 (e) The failure of any Lender to make the Advance to be made by it as part of any Borrowing
shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on
the date of any Borrowing. 
 SECTION 2.03. Issuance of Letters of Credit; Drawings and Reimbursements; Auto-Extension
Letters of Credit; Funding of Participations. (a) Procedures for Issuance and Amendment of Letters of Credit; Auto-Extension Letters of Credit. (i) Each Letter of Credit shall be issued or amended, as the case may be, upon the
request of the Related 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 such 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 (a) the date which is twelve (12) months after the proposed issuance date and (b) the Letter of Credit Expiration Date (or such later date as may be agreed by the Revolving Lenders in accordance with
Section 2.01(g)); (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; (G) whether such Letter of Credit is to be or, in the case of any amendment to any Letter of Credit, is, an AYE Letter of Credit, AESC Indirect Letter of Credit or AESC Direct Letter of Credit; and
(H) 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 Issuing Bank
(A) the Letter of Credit to be amended; (B) the proposed date of amendment thereof (which shall be a Business Day); (C) the nature of the proposed amendment; and (D) such other matters as such Issuing Bank may require.
Additionally, the Related 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 Related 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 Related 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

  

					
	AYE Refinancing Credit Agreement	  	43	  	

 
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 such Related Borrower (or the applicable Subsidiary) 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 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 Related 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 Related Borrower of an Insolvency Proceeding with respect to such Related Borrower or any of its Subsidiaries, 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
Related 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(g)); 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 Sections 2.01(d), (e) or (f) 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 Related 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 Related 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 Related Borrower shall reimburse such Issuing Bank through the Administrative Agent in an amount equal to the 
  

					
	AYE Refinancing Credit Agreement	  	44	  	

 
amount of such drawing. If the Related 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 Related Borrower shall be deemed to have requested a Revolving
Borrowing of Base Rate Advances to be disbursed on the Honor Date in an amount equal to the Unreimbursed Amount, without regard to the minimum and multiples specified in Section 2.01 for the principal amount of Base Rate Advances, but subject
to the other conditions set forth in Section 2.01 and the conditions set forth in Section 3.02 (other than the delivery of a Notice of Borrowing). Any notice given by such Issuing Bank or the Administrative Agent pursuant to this
Section 2.03(b) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice. 
 (ii) Each 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 Related
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 Related 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, any 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

  

					
	AYE Refinancing Credit Agreement	  	45	  	

 
such making of an L/C Advance shall relieve or otherwise impair the obligation of the Related 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. 
 (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 Related 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 2.11 (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 Borrowers 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 Related Borrower hereby assumes all risks
of the 
  

					
	AYE Refinancing Credit Agreement	  	46	  	

 
acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not,
preclude such Related Borrower from pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of the Issuing Bank, the Administrative Agent, nor any of the respective
correspondents, participants or assignees of such Issuing Bank, shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.03(j); provided, however, that anything in such
clauses to the contrary notwithstanding, the Related Borrower may have a claim against an Issuing Bank, and such Issuing Bank may be liable to such Related Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential
or exemplary, damages suffered by such Related Borrower which such Related 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 a 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(g)), as of such later expiry date), any Letter of Credit for any reason remains outstanding and
partially or wholly undrawn, AYE 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(g)), as the case may be). AYE 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 Related Borrower upon issuing an L/C Credit Extension (including any such agreement applicable to Existing L/Cs), (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. 
  

					
	AYE Refinancing Credit Agreement	  	47	  	

 (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 Related Borrower shall be obligated to reimburse the Issuing Bank hereunder for any and all drawings under such Letter of Credit.
The Related Borrower hereby acknowledges that the L/C Credit Extensions for the account of Subsidiaries inures to the benefit of such Related Borrower, and that such Related 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 Related 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 Loan Document; 

(ii) the existence of any claim, counterclaim, setoff, defense or other right that the Related 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 
  

					
	AYE Refinancing Credit Agreement	  	48	  	

 (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 Related Borrower. 
 The Related 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 such Related Borrower’s instructions or other irregularity, such Related Borrower will immediately notify the Issuing Bank. The Related 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) Acts and Omissions of Beneficiaries. Each
Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit issued at its request 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 relevant Borrower shall have a claim against such Issuing Bank, and such Issuing Bank shall be liable to such Borrower, to the extent of any direct, but not
consequential, damages suffered by such Borrower that such 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. Each 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 made to such Borrower and which are then outstanding. Without
prejudice to the foregoing, AYE shall repay to the Administrative Agent for the ratable account of the Term Lenders the aggregate principal amount of all Term Advances in consecutive quarterly installments. The initial such installment shall be due
and payable on September 30, 2006, and each installment thereafter shall be due and payable on each Quarterly Date occurring thereafter. Each such installment shall be in an amount equal to 0.25% of the aggregate principal amount of all Term
Advances as of the date such Term Advances were disbursed to AYE.

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 their respective Commitments with respect to such Facility. 
 (b) Mandatory. (i) So long as the Revolving Facility is in excess of $250,000,000, the Revolving Facility shall be automatically
and permanently reduced on each date on which prepayment of outstanding L/C Borrowings and Revolving Advances is required to be made pursuant to Section 2.06(b) by an amount equal to the applicable Reduction Amount (or portion thereof);
provided that, for the avoidance of doubt, reduction of the Revolving Facility pursuant to this clause (i) shall cease when the Revolving Facility is equal to $250,000,000. 
 (ii) All unused Term Commitments shall terminate on the earlier to occur of (a) the Closing Date (after giving effect to the Term
Borrowing made on such date) or (b) the termination in full of the Term Commitments in accordance with Section 6.01 (such date, the “Term Commitment Termination Date”). 
 (iii) The Revolving Commitments shall terminate on the earlier to occur of (a) 5:00 p.m. (New York City time) on the Final Maturity
Date, (b) the termination in full of the Revolving Commitments pursuant to Section 2.05(a), or (c) the termination of the Revolving Commitments in accordance with Section 6.01. 
 SECTION 2.06. Prepayments. (a) Optional. Each Borrower may, with respect to Advances made to it, upon at least one
Business Day’s notice in the case of Base Rate Advances and three Business Days’ notice in the case of Eurodollar Rate Advances, in each case to the Administrative Agent stating the proposed date and aggregate principal amount of the
prepayment, and if such notice is given such Borrower shall, prepay the outstanding aggregate principal amount of the Advances comprising part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such
prepayment on the aggregate principal amount prepaid; provided that (i) each partial prepayment shall be in an aggregate principal amount of $2,000,000 or an integral multiple of $1,000,000 in excess thereof and (ii) if any
prepayment of a Eurodollar Rate Advance is made on a date other than the last day of an Interest Period for such Advance, such Borrower shall also pay any amounts owing pursuant to Section 8.04(d). Any optional prepayment by AYE of the Term
Advances under this Section 2.06(a) shall be applied to the remaining amortization installments of the Term Facility in any one of the following manners, as directed by AYE in writing to the Administrative Agent (or, in the absence of any such
direction received by the Administrative Agent prior to the relevant prepayment date, in accordance with clause (i) below): (i) in inverse order of maturity with respect to the remaining amortization installments, (ii) to all
remaining amortization installments on a pro rata basis or (iii) to the next succeeding four amortization installments as of the date of such prepayment in direct order of maturity as among such four installments and, thereafter, to the
remaining amortization installments on a pro rata basis.

owned Subsidiary of AYE or (y) royalty payments are received in connection with the Buffalo Reserve Project; provided further notwithstanding anything to the contrary in this clause (b), (x) AYE, its Regulated Subsidiaries and any
Buffalo Creek SPV shall be entitled to retain the first $100,000,000 of Net Cash Proceeds from any other sale, transfer or other disposition in respect of any of the Assets of AYE, its Regulated Subsidiaries or any Buffalo Creek SPV received by AYE,
its Regulated Subsidiaries and any Buffalo Creek SPV in the aggregate plus an amount equal to (A) the aggregate principal amount of the Term Facility optionally prepaid by AYE pursuant to Section 2.06(a) and (B) the aggregate
amount of any optional prepayment of the Revolving Facility pursuant to Section 2.06(a) (if and to the extent the Revolving Commitments are terminated by AYE concurrently with such prepayment by AYE pursuant to Section 2.05(a)), in the
case of clauses (A) and (B) above, so long as such prepayment was funded with the proceeds of any sale, transfer or other disposition of any Asset by AYE, any Regulated Subsidiary or any Buffalo Creek SPV not otherwise required to be
applied to mandatorily prepay the Advances in accordance with this Section 2.06(b), and shall not be required to repay Term Advances, L/C Borrowings or Revolving Advances or Cash Collateralize L/C Obligations pursuant to this

Creek SPVs in the aggregate. 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, second, to repay L/C Borrowings
outstanding at such time until all such 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

to the applicable Lender or Issuing Bank, all accrued fees, costs and expenses, accrued interest thereon, if any, and any other amounts due under the Loan Documents in respect of the principal amount of the Advances or L/C Borrowings so prepaid,
including pursuant to Section 8.04(e).

 (i) Base Rate Advances. During such periods as such Advance is a Base Rate Advance, a rate per annum equal at
all times to the sum of (A) the Base Rate in effect from time to time plus (B) the Applicable Margin in effect from time to time, payable in arrears each Quarterly Date during such periods and on the date such Base Rate Advance
shall be Converted or paid in full. 
 (ii) Eurodollar Rate Advances. During such periods as such Advance

effect from time to time, payable in arrears on the last day of such Interest Period and, if such Interest Period has a duration of more than three months, on such day that occurs during such Interest Period every three months from the date of such
Interest Period and on the date such Eurodollar Rate Advance shall be Converted or paid in full. 
 (b) Default Interest.
Upon the occurrence and during the continuance of an Event of Default, each Borrower shall pay interest on (i) the unpaid and overdue principal amount of each Advance made to it and owing to each Lender, payable in arrears on the dates referred
to in clause (a)(i) or (a)(ii) above and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid on such Advance pursuant to clause (a)(i) or (a)(ii) above and
(ii) to the fullest extent permitted by Applicable Law, the amount of any interest, fee or other amount payable by such Borrower under the Loan Documents that is not paid by it when due, from the date such amount shall be due until such amount
shall be paid in full, payable in arrears on the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to 2% per annum above the rate per annum required to be paid, in the case of
interest, on the Type of Advance on which such interest has accrued pursuant to clause (a)(i) or (a)(ii) above and, in all other cases, on Base Rate Advances pursuant to clause (a)(i) above. 
 (c) Notice of Interest 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 2.10(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 any Borrower, the Administrative
Agent shall give notice to such Borrower and each Lender of the applicable Interest Period and the applicable interest rate determined by the Administrative Agent for purposes of clause (a)(i) or (a)(ii) above. 
 SECTION 2.08. Fees. (a) Commitment Fee. AYE shall pay to the Administrative Agent for the account of the Revolving Lenders a
commitment fee from the date

  

					
	AYE Refinancing Credit Agreement	 	52	 	

 
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 the average daily Unused Commitment of such Revolving Lender during such fiscal quarter. 
 (b) Letter
of Credit Fees. The Related 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 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. If there is any change in the Applicable Margin during any quarter, the daily maximum amount of each Letter of Credit Fee shall be computed and
multiplied by the Applicable Margin separately for each period during such quarter that such Applicable Margin was in effect. Notwithstanding anything to the contrary contained herein, upon the request of the Required Revolving Lenders, while any
Default exists, all Letter of Credit Fees shall accrue at the Applicable Margin plus 2%. 
 (c) Fronting Fee and
Documentary and Processing Charges Payable to Issuing Bank, Etc. The Related Borrower shall pay directly to the relevant Issuing Bank for its own account a fronting fee with respect to each Letter of Credit issued at the request of such Related
Borrower 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 Related
Borrower shall, with respect to all Letters of Credit issued at its request, pay directly to the 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) Agent Fees. AYE shall pay to the Administrative Agent for their own account such fees as may from time to time be agreed between
AYE and the Administrative Agent. 
 SECTION 2.09. 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 AYE through the Administrative Agent,
(i) each Eurodollar Rate Advance will

  

					
	AYE Refinancing Credit Agreement	 	53	 	

 
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 AYE that such Lender has determined that the circumstances causing such suspension no longer exist; provided that, before making any such demand, such Lender agrees to use reasonable efforts
(consistent with its internal policy and legal and regulatory restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Lender or its Eurodollar Lending Office to continue to perform its
obligations to make Eurodollar Rate Advances or to continue to fund or maintain Eurodollar Rate Advances and would not, in the judgment of such Lender, be otherwise disadvantageous to such Lender. 
 SECTION 2.10. Interest Elections. (a) Optional. (i) Each Borrower may on any Business Day elect to Convert all or any
portion of the Advances comprising the same Borrowing made to such Borrower 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 2.10.
Each Borrower may elect different options with respect to different portions of the Borrowing made to such Borrower, in which case each such portion shall be allocated ratably among the Lender Parties 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 2.10(a), a 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 Lender Parties 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 Borrowings, 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, such 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 issuing such notice.

  

					
	AYE Refinancing Credit Agreement	 	54	 	

 (iii) If, on the expiration of any Interest Period in respect of any Eurodollar Rate
Advances made to a Borrower, such Borrower shall have failed to deliver a Notice of Conversion/Continuation, then, unless such Advances are repaid as provided herein, such Borrower shall be deemed to have elected to Convert such Advances to Base
Rate Advances. No Advances may be Converted into, or Continued as, Eurodollar Rate Advances if an Event of Default has occurred and is continuing, unless the Administrative Agent and the Required Lenders shall have otherwise consented in writing.

 (iv) Upon receipt of any Notice of Conversion/Continuation, the Administrative Agent shall promptly notify each Lender Party
of the details thereof and of such Lender Party’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 any 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 AYE 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 2.11. 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 to any Borrower 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 to any Borrower (excluding, for purposes of this Section 2.11, 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 such Borrower shall from time to time, upon demand by such Lender Party (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender Party additional amounts sufficient to compensate
such Lender Party for such increased cost; provided, however, that a Lender Party claiming additional amounts under this Section 2.11(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

  

					
	AYE Refinancing Credit Agreement	 	55	 	

 
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 AYE 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), AYE 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
AYE by such Lender Party shall be conclusive and binding for all purposes, absent manifest error. 
 (c) If, with respect to any
Eurodollar Rate Advances made to any Borrower 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 AYE 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 AYE that
such Lenders have determined that the circumstances causing such suspension no longer exist. 
 SECTION 2.12. Payments and
Computations. (a) Each Borrower shall make each payment hereunder and under the Notes required of it, regardless of any right of counterclaim 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 such payment by such Borrower is in respect of principal, interest, commitment fees or any other Obligation then payable hereunder by such Borrower and
under its 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 by such Borrower 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

  

					
	AYE Refinancing Credit Agreement	 	56	 	

 
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) Each Borrower hereby authorizes each Lender Party and each of its Affiliates, if and to the extent payment owed to such Lender Party by
such 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 such Borrower’s accounts with such Lender Party or
such Affiliate any amount so due. 
 (c) 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. 
 (d) 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. 
 (e) Unless the Administrative Agent shall have received notice from AYE prior to the date on
which any payment is due by any Borrower to any Lender Party hereunder that such Borrower will not make such payment in full, the Administrative Agent may assume that such 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 such 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. 
 (f) If the Administrative Agent receives funds from any Borrower for application to the Obligations of such Borrower under the Loan Documents under circumstances for which the Loan 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

  

					
	AYE Refinancing Credit Agreement	 	57	 	

 
Lender Party’s proportionate share of the principal amount of all outstanding Advances of such Borrower and the L/C Obligations relating to such Borrower then outstanding, in repayment or
prepayment of such of the outstanding Advances or other Obligations owed by such Borrower to such Lender Party, and for application to such principal installments, as the Administrative Agent shall direct; provided that no Borrower shall be
liable to any Lender Party with respect to any such distribution by the Administrative Agent. 
 (g) 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 2.09, 2.11 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. Each Borrower agrees that any Lender Party so purchasing an interest or participating interest from another Lender Party pursuant to this Section 2.12 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 such Borrower in the amount of such interest or
participating interest, as the case may be. 
 SECTION 2.13. Taxes. (a) Any and all payments by each Borrower
hereunder or under the Notes shall be made, in accordance with Section 2.12, 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, as the case may be, (i) taxes imposed on (or

  

					
	AYE Refinancing Credit Agreement	 	58	 	

 
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 and the transactions contemplated hereby), or taxes measured by its net worth or shareholder’s capital, by the United States, or by the jurisdiction under the laws of which such recipient is organized or in which
its Applicable Lending Office is located, (ii) any branch profits taxes imposed by the United States or any similar tax imposed by any other jurisdiction in which the Applicable Lending Office of any Lender Party is located and
(iii) withholding taxes excluded pursuant to clause (e) of this Section 2.13 (all such non-excluded taxes, including levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under the
Notes being hereinafter referred to as “Taxes”). If any Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any of the Notes to any Lender Party or the Administrative
Agent, (A) the sum payable by such Borrower shall be increased as may be necessary so that after such 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) such Borrower shall make all such deductions and
(C) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with Applicable Law. 
 (b) In addition, each Borrower shall pay any present or future stamp, documentary, excise, property 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 the Notes, 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 “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) Each Borrower shall indemnify each Lender Party and the Administrative Agent for and hold them harmless against the full amount of 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
by any relevant Borrower of Taxes, such 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 any relevant Borrower

  

					
	AYE Refinancing Credit Agreement	 	59	 	

 
through an account or branch outside the United States or by or on behalf of any Borrower by a payor that is not a United States person, if such Borrower determines that no Taxes are payable in
respect thereof, such 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 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 AYE (but only so long thereafter as such Lender Party remains lawfully able to do so), provide each of the Administrative Agent and AYE with two duly completed copies of (i) Internal Revenue Service Form
W-8ECI, or any successor form thereto, certifying that the payments received from any 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 each 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 any 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 any 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 AYE, provide each of the Administrative Agent and AYE 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 AYE at any time that it determines that it is no
longer in a position to provide any previously delivered certificate to AYE (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 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 Taxes for periods governed by such forms; provided, however, that if, at the effective date of the Assignment
and Acceptance pursuant to which a Lender Party becomes a party to this Agreement, the Lender Party assignor was entitled to payments under subsection (a)

  

					
	AYE Refinancing Credit Agreement	  	60	  	

 
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 Taxes shall include (in addition to withholding
taxes that may be imposed in the future or other amounts otherwise includable in 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 AYE 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 AYE 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 Taxes imposed by the United States by reason of such failure; provided that should a
Lender Party become subject to Taxes because of its failure to deliver a form required hereunder, each Borrower shall take such steps as such Lender Party shall reasonably request to assist such Lender Party to recover such 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 Taxes paid or reimbursed by any Borrower pursuant
to subsection (a) or (c) above in respect of payments under the Loan 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 such 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 each 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. Each Borrower agrees that upon notice by any Lender
Party to such 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

  

					
	AYE Refinancing Credit Agreement	  	61	  	

 
Lender Party, such 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 Loan 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, the name of the Related Borrower for such Advance or L/C Borrowing, 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 any Borrower to each Lender Party; and (iv) the amount of any sums received by
the Administrative Agent from any 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 any 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
Borrowers 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 each Borrower agrees that it shall use proceeds of Advances made to it and each Letter of Credit issued at its request) solely (a) on the Closing Date (i) in the case of the Initial Borrowing, to
repay (together with the Term Advances) in full the Existing AYE Debt and (ii) to continue the Existing L/Cs as AYE Letters of Credit under this Agreement, (b) with respect to the proceeds of the Term Advances (and together with proceeds
of Revolving Advances made as part of the Initial Borrowing), to repay in full the Existing AYE Debt and (c) each subsequent Revolving Borrowing and Letter of Credit, for working capital for AYE and, subject to the limitations herein, its
Subsidiaries.

 ARTICLE VII 
 THE ADMINISTRATIVE AGENT

as agent on its behalf and to exercise such powers and discretion under this Agreement and the other Loan Documents as are delegated to the Administrative Agent by the terms hereof and thereof, together with such powers and discretion as are

Lender that is the payee of such Note, as assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07; (b) may consult with legal counsel (including counsel for any Borrower), independent public accountants and other

Lender Party for the due 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 Loan

telegram, telecopy or telex) reasonably believed by it to be genuine and signed or sent by the proper party or parties. 
 SECTION 7.03. CNAI, CGMI, Citibank, CSCI and Affiliates. With respect to its Commitment, the Advances made by it, the L/C Credit Extensions and the Notes issued to it, CNAI, CGMI, Citibank and CSCI shall have the same rights and
powers under the Loan Documents as any other Lender and may exercise the same as though it were not the Administrative Agent or an Arranger Party, respectively; and the terms “Lender”, “Lenders”, “Revolving
Lender”, “Revolving Lenders”, “Term Lender” or “Term Lenders” shall, unless otherwise expressly indicated, include each of CNAI, CGMI, Citibank and CSCI in its individual capacity, as

Borrower, any Subsidiary of any Borrower and any Person that may do business with or own securities of any Borrower or any such Subsidiary, all as if CNAI, CGMI, Citibank and CSCI were not the Administrative Agent or an Arranger Party, respectively,
and without any duty to account therefor to the Lenders.

Party or any other Lender Party, and based on the financial statements referred to in Sections 4.01(f), 5.03(b) and 5.03(c) hereto and such other documents and information as it has deemed

Agent, any Arranger Party or any other Lender Party and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other
Loan Documents to which it is a party. 
 SECTION 7.05. Indemnification. (a) Each Lender severally agrees to
indemnify the Administrative Agent and the Arranger Parties (in each case to the extent not promptly reimbursed by the Borrowers) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent or any Arranger Party, as the
case may be, in any way relating to or arising out of the Loan Documents or any action taken or omitted by the Administrative Agent or any Arranger Party under the Loan Documents (collectively, the “Indemnified Costs”);
provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting directly and primarily from the Administrative
Agent’s 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 any 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 such Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such
investigation, litigation or proceeding is brought by any Lender or any other Person. 
 (b) Each Lender severally agrees to
indemnify each Issuing Bank (to the extent not promptly reimbursed by any Borrower) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against any Issuing Bank in any way relating to or arising out of the Loan Documents or any action taken or omitted
by such Issuing Bank under the Loan Documents (including the issuance or transfer of, or payment or failure to pay under, any Letter of Credit); provided that no Lender shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting directly and primarily from such Issuing Bank’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of
competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse such Issuing Bank promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable
by any Borrower under Section 8.04, to the extent that such Issuing Bank is not promptly reimbursed for such costs and expenses by such Borrower. 
  

					
	AYE Refinancing Credit Agreement	  	94	  	

 (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 such Issuing Bank shall 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 Lenders 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 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 shall be responsible for the failure of any other Lender to reimburse the Administrative Agent, any Arranger Party or any Issuing Bank, as the case may be, for such other Lender’s
ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the agreement and obligations of each Lender contained in this Section 7.05 shall survive the payment in full of principal, interest
and all other amounts payable hereunder and under the other Loan Documents. 
 SECTION 7.06. Successor Administrative
Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lender Parties and the Borrowers 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 Loan 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 Loan Documents. 
 SECTION 7.07. Liability. Neither the Administrative 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. Treatment of Lenders. Each of the Administrative Agent and the
Arranger Party may treat the Lender Parties as the holders of Commitments or L/C Credit

  

					
	AYE Refinancing Credit Agreement	  	95	  	

 
Extensions and as the absolute owners thereof for all purposes under this Agreement and the other Loan Documents unless the Administrative Agent and the Arranger Party shall receive notice to the
contrary from such Lender Party. 
 SECTION 7.09. Miscellaneous. (a) Instructions. The Administrative Agent shall
have the right at any time to seek instructions concerning the administration of its duties and obligations hereunder or under any other Loan 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 do not unambiguously mandate the action the Administrative Agent is to take or not to take in connection therewith under the circumstances then existing, or the Administrative
Agent is in doubt as to what action it is required to take or not to take, the Administrative Agent (other than the actions required of it under the final sentence of Section 7.01) 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 Loan Documents shall be construed to require the Administrative Agent to expend or risk its own funds or otherwise to incur any personal financial liability in
the performance of any of its duties hereunder or thereunder. The Administrative Agent shall not be under any obligation to exercise any of the rights or powers vested in it by this Agreement or the other Loan Documents, at the request or direction
of any Borrower, or any Lender Party, (i) if any action it has been requested or directed to take would be contrary to Applicable Law, or (ii) unless the Administrative Agent shall have been offered security or indemnity reasonably
satisfactory to it against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction (including interest thereon from the time incurred until reimbursed). 
 SECTION 7.10. Arranger Parties. Except as set forth in Sections 7.03 and 8.12, none of the Lenders or other Persons identified on the
facing page or signature pages of this Agreement as a “joint lead arranger”, “lead arranger”, “joint book runner” or “syndication agent”, shall have any right, power, obligation,
liability, responsibility or duty under this Agreement or any other Loan Document other than, in the case of such Lenders, those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders or other Persons so identified
shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders or other Persons so identified in deciding to enter into this Agreement or in
taking or not taking action hereunder.

this Agreement, the other Loan Documents, any Letter of Credit, any of the transactions contemplated herein or therein or the actual or proposed use of the proceeds of the Advances or any L/C
Borrowings, (ii) the issuance or transfer of, or payment or failure to pay under, any Letter of Credit or (iii) the actual or alleged presence of Hazardous Materials requiring remediation or other response pursuant to Environmental Law on
any property of such Borrower or any of its Subsidiaries or any Environmental Action relating in any way to such Borrower or any of its Subsidiaries, except to the extent such claim, damage, loss, liability or expense is found in a final,
non-appealable judgment by a court of competent jurisdiction to have resulted directly and primarily from such Indemnified Party’s gross negligence or willful misconduct. In the case of an investigation, litigation or other proceeding to which
the indemnity in this Section 8.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by any Borrower, its directors, equityholders or creditors or an Indemnified Party or any
other Person, whether or not any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. Each Borrower also agrees not to assert any claim against the Administrative Agent, any Lender
Party or any of their Affiliates, or any of their respective officers, directors, employees, agents, attorneys and advisors, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to
the Facilities, the actual or proposed use of the proceeds of the Advances or any Letter of Credit, the Loan Documents or any of the transactions contemplated by the Loan Documents.

modification of this Agreement or the other Loan Documents, the resignation or removal of the Administrative Agent, and the provision of any subsequent or additional indemnity by any Person. 
 (d) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by any Borrower to or for the account of a Lender
Party other than on the last day of the Interest Period for such Advance, as a result of a payment or Conversion pursuant to Section 2.06(a), 2.10(b) or 2.11(c), acceleration of the maturity of the Notes pursuant to Section 6.01 or for any
other reason, or if any Borrower fails to make any payment or prepayment of an Advance for which a notice of prepayment has been given or that is otherwise required to be made, whether pursuant to Section 2.04, 2.06 or 6.01 or otherwise, such
Borrower shall, 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 any amounts required to compensate such Lender Party for any additional
losses, costs or expenses that it may reasonably incur as a result of such payment or Conversion or such failure to pay or prepay, as the case may be, including any loss (excluding loss of anticipated profits), cost or expense incurred by reason of
the liquidation or reemployment of deposits or other funds acquired by any Lender Party to fund or maintain such Advances. 
 (e) If any Borrower fails to pay when due any costs, expenses or other amounts payable by it under any Loan Document, including fees and expenses of counsel and indemnities, such amount may be paid on behalf of such Borrower by the
Administrative Agent or any Lender Party, in its sole discretion.

 SECTION 8.05. Right of Set-off. Upon (a) the occurrence and during the
continuance of any Event of Default and (b) the making of the request or the granting of the consent specified by Section 6.02 to authorize the Administrative Agent to declare the Notes due and payable pursuant to the provisions of
Section 6.02, the Administrative Agent and each Lender Party and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and otherwise apply any and all
deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Administrative Agent, such Lender Party or such Affiliate to or for the credit or the account of any Borrower
against any and all of the Obligations of such Borrower now or hereafter existing under the Loan Documents, irrespective of whether the Administrative Agent or such Lender Party shall have made any demand under this Agreement or such Note or Notes
and although such Obligations may be unmatured. The Administrative Agent and each Lender Party agrees promptly to notify the Borrowers after any such set-off and application; provided, however, that the failure to give such notice
shall not affect the validity of such set-off and application. The rights of the Administrative Agent and each Lender Party and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of
set-off) that the Administrative Agent, such Lender Party and their respective Affiliates may have. 
 SECTION 8.06. Binding
Effect. This Agreement shall become effective at such time as it shall have been executed by the Borrowers and the Administrative Agent and the Administrative Agent shall have been notified by each Initial Lender Party that such Initial Lender
Party has executed it and thereafter shall be binding upon and inure to the benefit of the Borrowers, the Administrative Agent and each Lender Party and their respective successors and assigns, except that each Borrower shall not have the right to
assign its rights hereunder or any interest herein without the prior written consent of the Lender Parties. 
 SECTION 8.07.
Assignments and Participations. (a) Each Lender Party may and, if requested by AYE (following (i) a demand by such Lender Party for the payment of additional compensation pursuant to Section 2.11 or 2.13, (ii) an assertion
by such Lender Party pursuant to Section 2.09 that it is unlawful for such Lender Party to make Eurodollar Rate Advances or (iii) a failure by such Lender Party to approve any amendment or waiver pursuant to Section 8.01, provided
that such amendment or waiver would otherwise have been effective but for such Lender Party’s failure, together with the failure of any other Lender Party to which AYE has made a similar request under this clause (a), to approve such
amendment or waiver, provided further that, with respect to clause (iii), such failure to approve shall have continued for a period of not less than five Business Days following written notice by AYE to such Lender Party of such request by
AYE) shall, assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including (y) 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 held by it, and/or (z) all or a portion of its Term Commitment, the Term Advances owing to it, and the Term Note or Term Notes held by it), including any pledge or assignment to secure obligations to a
Federal Reserve Bank; provided, however, that (i) except in the case of an assignment to a Person that, immediately prior to such assignment, was a Lender Party, an Affiliate of any Lender Party or an Approved Fund or an assignment of
all of a Lender Party’s rights and obligations under this Agreement, the aggregate amount of (A) any Term Commitment or Term Advance being assigned to such Person pursuant to such assignment

  

					
	AYE Refinancing Credit Agreement	  	101	  	

 
(determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000 (or such lesser amount as shall be approved by the
Administrative Agent) and shall be in increments of $1,000,000 in excess thereof, or (B) any Revolving Commitment or Revolving Advance being assigned to such Eligible Assignee pursuant to such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event be less than $5,000,000 (or such lesser amount as shall be approved by the Administrative Agent) and shall be in increments of $1,000,000 in excess thereof, (ii) each
such assignment shall be to an Eligible Assignee; provided that the Issuing Bank shall have sole discretion to consent to such Person being an Eligible Assignee, (iii) (A) with respect to any Term Commitment or any Term Advance, no
such assignments shall be permitted without the consent of the Administrative Agent (such consent not to be unreasonably withheld) and, so long as no Specified Default has occurred and is continuing, the consent of AYE (such consent not to be
unreasonably withheld), except assignments to any other Lender Party, an Affiliate of any Lender, an Approved Fund or 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 any Issuing Bank 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 AYE (such consent not to be unreasonably withheld), except, with respect to AYE’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 AYE if such assignment is being made pursuant to a request of AYE 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 AYE
pursuant to this Section 8.07(a) shall be arranged by AYE 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 AYE 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
AYE 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 Loan Documents (including, without limitation, any amounts owing under Section 2.11, 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
any Letter of Credit Commitment at any time;

  

					
	AYE Refinancing Credit Agreement	  	102	  	

 
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, AYE 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 2.11, 2.13 and 8.04 to the extent any claim thereunder relates to an event arising prior to such assignment) and be released from its obligations
under this Agreement (and, in the case of an Assignment and Acceptance covering all of the remaining portion of an assigning Lender’s or Issuing Bank’s rights and obligations under this Agreement, such Lender or Issuing Bank shall cease to
be a party hereto). 
 (d) By executing and delivering an Assignment and Acceptance, each Lender Party assignor thereunder and
each assignee thereunder confirm to and agree with each other and the other parties thereto and hereto as follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender Party makes no representation or warranty and
assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan 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 any Borrower or the performance or
observance by any Borrower of any of its obligations under any Loan 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 Loan
Document, together with copies of the financial statements referred to in Sections 4.01(f), 5.03(b) and 5.03(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 Loan Document; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes
the Administrative Agent to take such action as agent on its behalf and to exercise such powers and discretion under the Loan Documents as are delegated to the Administrative 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 Loan Documents are required to be
performed by it as a Lender or Issuing Bank, as the case may be. 
  

					
	AYE Refinancing Credit Agreement	  	103	  	

 (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 Borrowers, 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 Borrowers 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 Borrowers. In the case of any assignment by a Lender, within five Business Days after
its receipt of such notice, the Borrowers, at their 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 any Borrower or any Affiliate of any 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) 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, (ii) such Lender Party shall remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) such Lender Party shall remain the holder of any such Note for all purposes of this Agreement, (iv) the Borrowers, 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 (v) no participant under any such participation shall have any right to approve any amendment or waiver of any provision of any
Loan Document, or any consent to any departure by any 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.

  

					
	AYE Refinancing Credit Agreement	  	104	  	

 (h) Notwithstanding anything in this Agreement to the contrary (including any other
provision regarding assignments, participations, transfers or novations), any Lender (a “Granting Lender”) may, without the consent of any other party hereto, grant to a special purpose vehicle (whether a corporation,
partnership, limited liability company, trust or otherwise, an “SPV”) sponsored or managed by the Granting Lender or any Affiliate thereof, a participation in all or any part of any Advance (including the Commitment therefor)
that such Granting Lender has made or will make pursuant to this Agreement; provided that (i) such Granting Lender’s obligations under this Agreement (including its Commitment) shall remain unchanged; (ii) such Granting Lender
shall remain the holder of its Note for all purposes under this Agreement; and (iii) the Borrowers, 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 Loan 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 Loan 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 any Borrower furnished to such Lender Party by or on behalf of such 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.

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 Loan Documents to which it is a party, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally
agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York State court or, to the fullest extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final
judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that any party may otherwise
have to bring any action or proceeding relating to this Agreement or any of the other Loan 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 Loan 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. Each 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 Loan 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 AYE, disclose to any Person (i) any confidential, proprietary or non-public information of the Borrowers furnished to the Administrative Agent, the Arranger Parties or the Lender
Parties by the Borrowers (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 Loan 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

  

					
	AYE Refinancing Credit Agreement	  	106	  	

 
authority having jurisdiction over it or to the extent necessary for purposes of enforcing this Agreement or any other Loan 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 Loan Document or any suit, action or proceeding relating
to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (vi) subject to an agreement containing provisions substantially the same as those of this Section 8.12, to any assignee or pledgee of or
participant in, or any prospective assignee or pledgee of or participant in, any of its rights or obligations under this Agreement (including 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 AYE. 
 (b) Neither the Administrative Agent, any Arranger Party nor any Lender Party shall, without the prior
written consent of AYE, use, either directly or indirectly, any of the Confidential Information except in connection with this Agreement and the other Loan 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 Loan 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 AYE 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 AYE 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 AYE’s counsel to
enable AYE 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, AYE 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. 
  

					
	AYE Refinancing Credit Agreement	  	107	  	

 (f) Neither the Administrative Agent, any Arranger Party nor any Lender Party shall make any
public announcement, advertisement, statement or communication regarding any Borrower, its Affiliates (insofar as such announcement, advertisement, statement or communication relates to such Borrower or the transactions contemplated hereby) or this
Agreement or the transactions contemplated hereby without the prior consent of AYE (such consent not to be unreasonably withheld or delayed).

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 Loan 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.

otherwise relating to the Notes, this Agreement, the other Loan 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. (a) Without prejudice to any agreement of any Borrower hereunder or under any other Loan Document, the
indemnification and expense reimbursement obligations of such Borrower contained in the Existing Credit Agreement shall survive the Closing Date and the payment in full of principal, interest and all other amounts payable thereunder. 
 (b) Notwithstanding anything in this Agreement to the contrary, Sections 2.08(c), 7.05, 7.10, 8.04, 8.10, 8.11, 8.12 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

  

					
	AYE Refinancing Credit Agreement	  	108	  	

 
to have been false or misleading, notwithstanding that such Lender Party may have had notice or knowledge or reason to believe that such representation or warranty was false or misleading at the
time such Advance or L/C Credit Extension was made. 
 SECTION 8.17. USA Patriot Act Notice. Each Lender Party and the
Administrative Agent (for itself and not on behalf of any Lender Party) hereby notifies each 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

 AYE REFINANCING CREDIT AGREEMENT 
 CERTAIN ENVIRONMENTAL MATTERS 

This Schedule incorporates by reference, and reference should be made to, Note 18, Commitments and Contingencies, in the Notes to Consolidated Financial
Statements of Allegheny Energy, Inc.’s quarterly report on Form 10-Q for the quarterly period ended March 31, 2006. 
 Clean Air
Act Matters
 Allegheny Energy, Inc. (“AYE”) and all of its subsidiaries (collectively
“Allegheny”) 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. Allegheny Energy Supply Company, LLC (“AE Supply”) and Monongahela Power Company (“Mon Power”) comply with current SO2 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 year-end 2009, 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. Allegheny 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 SO2 and NOX, 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 the Distribution Companies (collectively, Mon Power, West Penn and The Potomac Edison Company) 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. 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. On April 19, 2006 the magistrate judge assigned to the PA
Enforcement Action issued a report and recommendation that Allegheny’s motion to dismiss be denied. 
 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 appellate 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 AE Supply 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, 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. 

 Global Warming Class Action 
 On April 19, 2006, AYE, along with numerous other companies with coal-fired generation facilities and companies in other industries, was
named as a defendant in a class action in the United States District Court for the Southern District of Mississippi. On behalf of a purported class of residents and property owners in Mississippi who were harmed by Hurricane Katrina, the named
plaintiffs allege that the emission of greenhouse gases by defendants contributed to global warming, thereby causing Hurricane Katrina and plaintiffs’ damages. The plaintiffs seek unspecified damages. AYE has not yet been served with this
lawsuit. AYE 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 March 31, 2006, Allegheny had 801 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 $20.0 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. PADEP has since asked for information relating to post-1955 ash disposal. 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.
