Agent. The Company may from time to time pay, subject to the payment of any funding indemnification amounts required by Section 4.4 but without penalty or premium, all outstanding Eurodollar Advances or, in a minimum aggregate amount of
$10,000,000 or a higher integral multiple of $1,000,000, any portion of any outstanding Eurodollar Advance upon three (3) Business Days’ prior written notice to the Agent; provided that if, after giving effect to any such
prepayment, the principal amount of any Eurodollar Advance is less than $10,000,000, such Eurodollar Advance shall automatically convert into a Floating Rate Advance. If at any time the Aggregate Outstanding Credit Exposure exceeds the Available
Aggregate Commitment, the Company shall immediately repay Advances or cash collateralize LC Obligations in the Facility LC Collateral Account in accordance with the procedures set forth in Section 9.2, as applicable, in an aggregate principal
amount sufficient to cause the Aggregate Outstanding Credit Exposure to be less than or equal to the Available Aggregate Commitment. 
 2.8 Method of Selecting Types and Interest Periods for New Advances. The Company shall select the Type of Advance and, in the case of each Eurodollar Advance, the Interest Period applicable thereto
from time to time. The Company shall give the Agent irrevocable notice (a “Borrowing Notice”) not later than 10:00 a.m. (Los Angeles, California time) on the Borrowing Date of each Floating Rate Advance and not later than 10:00 a.m.
(Los Angeles, California time) three (3) Business Days before the Borrowing Date for each Eurodollar Advance, specifying: 
 (i) the Borrowing Date, which shall be a Business Day; 
 (ii) the
aggregate amount of such Advance; 
 (iii) the Type of Advance selected; and 

(iv) in the case of each Eurodollar Advance, the initial Interest Period applicable thereto. 

  
 -18-









 Promptly after receipt thereof, the Agent will notify each Bank of the contents of each Borrowing Notice.
Not later than 12:00 noon (Los Angeles, California time) on each Borrowing Date, each Bank shall make available its Loan in funds immediately available in Los Angeles, California to the Agent at its address specified pursuant to
Section 14.1. To the extent funds are received from the Banks, the Agent will make such funds available to the Company at the Agent’s aforesaid address. No Bank’s obligation to make any Loan shall be affected by any other
Bank’s failure to make any Loan. 
 2.9 Conversion and Continuation of Outstanding Advances. Floating Rate Advances
shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.9 or are repaid in accordance with Section 2.2 or 2.7. Each
Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Floating Rate Advance unless (x) such
Eurodollar Advance is or was repaid in accordance with Section 2.2 or 2.7 or (y) the Company shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period,
such Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period. Subject to the terms of Section 2.6, the Company may elect from time to time to convert all or any part of a Floating Rate Advance into a
Eurodollar Advance. The Company shall give the Agent irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of a Floating Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later
than 10:00 a.m. (Los Angeles, California time) at least three Business Days prior to the date of the requested conversion or continuation, specifying: 
 (i) the requested date, which shall be a Business Day, of such conversion or continuation; 
 (ii) the aggregate amount and Type of the Advance which is to be converted or continued; and 
 (iii) the amount of the Advance which is to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable thereto; 

provided that no Advance may be continued as, or converted into, a Eurodollar Advance if (x) such continuation or conversion would violate
any provision of this Agreement or (y) a Default or Event of Default exists. 
 2.10 Interest Rates, Interest Payment
Dates. (a) Subject to Section 2.11, each Advance shall bear interest as follows: 
 (i) at
any time such Advance is a Floating Rate Advance, at a rate per annum equal to the Floating Rate from time to time in effect; and 
 (ii) at any time such Advance is a Eurodollar Advance, at a rate per annum equal to the Eurodollar Rate for each applicable Interest Period. 
 Changes in the rate of interest on that portion or any Advance maintained as a Floating Rate Advance will take effect simultaneously with each change in the Floating Rate. 

  
 -19-









 (b) Interest accrued on each Floating Rate Advance shall be payable on each Payment Date and
on the Termination Date. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which such Eurodollar Advance is prepaid and on the Termination Date. Interest accrued on each
Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest on Eurodollar Advances, interest on Floating Rate Advances based on the
Federal Funds Effective Rate and the LC Fee shall be calculated for actual days elapsed on the basis of a 360-day year. Interest on Floating Rate Advances based on the Reference Rate shall be calculated for actual days elapsed on the basis of a 365-
or 366-day year, as appropriate. Interest on each Advance shall accrue from and including the date such Advance is made to but excluding the date payment thereof is received in accordance with Section 2.12. If any payment of principal of
or interest on an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day (unless, in the case of a Eurodollar Advance, such next succeeding Business Day falls in a new calendar
month, in which case such payment shall be due on the immediately preceding Business Day) and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment. 

2.11 Rate after Maturity. Any Advance not paid by the Company at maturity, whether by acceleration or otherwise, shall bear
interest until paid in full at a rate per annum equal to the higher of (i) the rate otherwise applicable thereto plus 2.00% or (ii) the Floating Rate plus 2.00%. 

2.12 Method of Payment; Sharing Set-Offs. (a) All payments of principal, interest and fees hereunder shall be made in
immediately available funds to the Agent at its address specified on its signature page to this Agreement (or at any other Lending Installation of the Agent specified in writing by the Agent to the Company), without setoff or counterclaim, not later
than 10:00 a.m. (Los Angeles, California time) on the date when due and shall (except in the case of Reimbursement Obligations for which the applicable LC Issuer has not been fully indemnified by the Banks, or as otherwise specifically required
hereunder) be applied ratably by the Agent among the Banks. Funds received after such time shall be deemed received on the following Business Day unless the Agent shall have received from, or on behalf of, the Company a Federal Reserve reference
number with respect to such payment before 1:00 p.m. (Los Angeles, California time) on the date of such payment. Each payment delivered to the Agent for the account of any Bank shall be delivered promptly by the Agent in the same type of funds
received by the Agent to such Bank at the address specified for such Bank in its Administrative Questionnaire or at any Lending Installation specified in a notice received by the Agent from such Bank. The Agent is hereby authorized to charge the
account of the Company maintained with Union Bank, if any, for each payment of principal, interest, Reimbursement Obligations and fees as such payment becomes due hereunder. Each reference to the Agent in this Section 2.12 shall also be
deemed to refer, and shall apply equally, to each LC Issuer, in the case of payments required to be made by the Company to such LC Issuer pursuant to Section 3.6. 
 (b) If any Bank shall fail to make any payment required to be made by it pursuant to Section 2.8, Section 2.15, Section 3.5 or Section 13.8, then the Agent
may, in its discretion and notwithstanding any contrary provision hereof, apply any amounts thereafter received by the Agent for the account of such Bank and for the benefit of the Agent or the LC Issuer to satisfy such Bank’s obligations under
such Sections until all such unsatisfied obligations are fully paid. 

  
 -20-









 2.13 Bonds; Record-keeping; Telephonic Notices. 

(a) Pursuant to the terms of the Existing Credit Agreement, the obligation of the Company to repay the Obligations are evidenced by one
or more Bonds. 
 (b) Each Bank shall maintain in accordance with its usual practice an account or accounts evidencing the
indebtedness of the Company to such Bank resulting from each Loan made by such Bank from time to time, including the amounts of principal and interest payable and paid to such Bank from time to time hereunder. 

(c) The Agent shall also maintain accounts in which it will record (i) the amount of each Loan made hereunder, the Type thereof and,
if applicable, the Interest Period with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Company to each Bank hereunder, (iii) the original stated amount of each Facility
LC and the amount of LC Obligations outstanding at any time, and (iv) the amount of any sum received by the Agent hereunder from the Company and each Bank’s share thereof. 

(d) The entries maintained in the accounts maintained pursuant to clauses (b) and (c) above shall be prima facie
evidence of the existence and amounts of the Obligations therein recorded absent manifest error; provided that the failure of the Agent or any Bank to maintain such accounts or any error therein shall not in any manner affect the obligation
of the Company to repay the Obligations in accordance with their terms. 
 (e) The Company hereby authorizes the Banks and the
Agent to make Advances based on telephonic notices made by any person or persons the Agent or any Bank in good faith believes to be acting on behalf of the Company. The Company agrees to deliver promptly to the Agent a written confirmation of each
telephonic notice signed by a Designated Officer. If the written confirmation differs in any material respect from the action taken by the Agent and the Banks, the records of the Agent and the Banks shall govern absent manifest error. 

2.14 Lending Installations. Subject to the provisions of Section 4.6, each Bank may book its Loans and its
participation in any LC Obligations and each LC Issuer may book the Facility LCs issued by it at any Lending Installation selected by such Bank or such LC Issuer, as the case may be, and may change its Lending Installation from time to time. All
terms of this Agreement shall apply to any such Lending Installation and the Loans shall be deemed held by the applicable Bank for the benefit of such Lending Installation. Each Bank may, by written or facsimile notice to the Company, designate a
Lending Installation through which Loans will be made by it or Facility LCs will be issued by it and for whose account payments on the Loans or payments with respect to Facility LCs are to be made. 

2.15 Non-Receipt of Funds by the Agent. Unless a Bank or the Company, as the case may be, notifies the Agent prior to the time on
the date on which it is scheduled to make payment to the Agent of (i) in the case of a Bank, the proceeds of a Loan or (ii) in the case of the Company, a payment of principal, interest or fees to the Agent for the account of the Banks,
that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available 

  
 -21-









 
to the intended recipient in reliance upon such assumption. If such Bank or the Company, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall,
on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers
such amount at a rate per annum equal to (i) in the case of payment by a Bank, the Federal Funds Rate for such day or (ii) in the case of payment by the Company, the interest rate applicable to the relevant Loan. 

ARTICLE III 

LETTER OF CREDIT FACILITY 
 3.1 Issuance. Each LC Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby letters of credit and, to the extent agreed to by any applicable LC Issuer,
direct pay letters of credit denominated in U.S. dollars (each, a “Facility LC”) and to renew, extend, increase, decrease or otherwise modify each Facility LC (“Modify,” and each such action a
“Modification”), from time to time from and including the date hereof and prior to the Termination Date upon the request of the Company; provided, however, that in no event shall (i) immediately after each such
Facility LC is issued or Modified, the Aggregate Outstanding Credit Exposure exceed the Available Commitment, (ii) immediately after each such Facility LC is issued or Modified, the amount of the LC Obligations exceed $150,000,000 and
(iii) a Facility LC (x) be issued later than 30 days prior to the scheduled Termination Date, (y) have an expiry date later than the earlier of (1) the date one year after the date of the issuance of such Facility LC (or, in the
case of any renewal or extension thereof, one year after such renewal or extension and provided that such Facility LC may contain customary “evergreen” provisions pursuant to which the expiry date is automatically extended by a specific
time period unless such LC Issuer gives notice to the beneficiary of such Facility LC at least a specified time period prior to the expiry date then in effect) and (2) the fifth Business Day prior to the scheduled Termination Date or
(z) provide for time drafts. 
 3.2 Participations. Upon the issuance or Modification by an LC Issuer of a Facility
LC in accordance with this Article III, such LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Bank, and each Bank shall be deemed, without further action by any party
hereto, to have unconditionally and irrevocably purchased from such LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to its Pro Rata Share. 

3.3 Notice. Subject to Section 3.1, the Company shall give the Agent and the applicable LC Issuer notice prior to
10:00 a.m. (Los Angeles, California time) at least three (3) Business Days prior to the proposed date of issuance or Modification of each Facility LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry
date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported thereby. Upon receipt of such notice, the Agent shall promptly notify each Bank, of the contents thereof and
of the amount of such Bank’s participation in such proposed Facility LC. Each Bank, shall within two (2) Business Days following the date on which it receives such notice from the Agent, notify the Agent whether such Bank consents to the
issuance or Modification of such Facility LC (which consent shall be in the sole and absolute discretion of such Bank), it being understood and agreed that unless and 

  
 -22-









 
until each Bank consents in writing to such issuance or Modification, such Facility LC will not be issued or Modified by the applicable LC Issuer. The issuance or Modification by an LC Issuer of
any Facility LC shall, in addition to the conditions precedent set forth in Article XI (the satisfaction of which such LC Issuer shall have no duty to ascertain), be subject to the conditions precedent that such Facility LC shall be
satisfactory to such LC Issuer and that the Company shall have executed and delivered such application agreement and/or such other instruments and agreements relating to such Facility LC as such LC Issuer shall have reasonably requested (each, a
“Facility LC Application”). In the event of any conflict between the terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement shall control. 

3.4 LC Fees. The Company shall pay to the Agent, for the account of the Banks ratably in accordance with their respective Pro Rata
Shares, a letter of credit fee (the “LC Fee”) at a per annum rate equal to the Applicable Margin for Eurodollar Rate Loans in effect from time to time on the daily undrawn stated amount of each Facility LC, such fee to be payable in
arrears on each Payment Date and the Termination Date (and, if applicable, thereafter on demand). The Company shall also pay to each LC Issuer for its own account (a) a fronting fee for each Facility LC at the time and in the amount separately
agreed by the Company and such LC Issuer, and (b) documentary and processing charges in connection with the issuance or Modification of and draws under Facility LCs in accordance with such LC Issuer’s standard schedule for such charges as
in effect from time to time. 
 3.5 Administration; Reimbursement by Banks. Upon receipt from the beneficiary of any
Facility LC of any demand for payment under such Facility LC, the applicable LC Issuer shall notify the Agent and the Agent shall promptly notify the Company and each other Bank as to the amount to be paid by such LC Issuer as a result of such
demand and the proposed payment date (the “LC Payment Date”). The responsibility of an LC Issuer to the Company and each Bank shall be only to determine that the documents (including each demand for payment) delivered under each
Facility LC issued by such LC Issuer in connection with such presentment shall be in conformity in all material respects with such Facility LC. Each LC Issuer shall endeavor to exercise the same care in the issuance and administration of the
Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by such LC Issuer, each Bank shall be unconditionally and
irrevocably liable without regard to the occurrence of any Default, Event of Default or any condition precedent whatsoever, to reimburse such LC Issuer on demand for (i) such Bank’s Pro Rata Share of the amount of each payment made by such
LC Issuer under each Facility LC issued by it to the extent such amount is not reimbursed by the Company pursuant to Section 3.6 below, plus (ii) interest on the foregoing amount to be reimbursed by such Bank, for each day
from the date of such LC Issuer’s demand for such reimbursement (or, if such demand is made after 10:00 a.m. (Los Angeles, California time) on such date, from the next succeeding Business Day) to the date on which such Bank pays the amount to
be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate for the first three days and, thereafter, at a rate of interest equal to the rate applicable to Floating Rate Advances. 

3.6 Reimbursement by Company. The Company shall be irrevocably and unconditionally obligated to reimburse the applicable LC Issuer
on the applicable LC Payment Date for any amounts to be paid by such LC Issuer upon any drawing under any Facility LC issued by it, without presentment, demand, protest or other formalities of any kind; provided that 

  
 -23-









 
neither the Company nor any Bank shall hereby be precluded from asserting any claim for direct (but not consequential) damages suffered by the Company or such Bank to the extent, but only to the
extent, caused by (i) the willful misconduct or gross negligence of such LC Issuer in determining whether a request presented under any Facility LC issued by it complied with the terms of such Facility LC or (ii) such LC Issuer’s
failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. All such amounts paid by the applicable LC Issuer and remaining unpaid by the Company
shall bear interest, payable on demand, for each day until paid at a rate per annum equal to (x) the rate applicable to Floating Rate Advances for such day if such day falls on or before the applicable LC Payment Date and (y) the sum of
1.00% plus the rate applicable to Floating Rate Advances for such day if such day falls after such LC Payment Date. The applicable LC Issuer will pay to each Bank ratably in accordance with its Pro Rata Share all amounts received by such LC
Issuer from the Company for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued by such LC Issuer, but only to the extent such Bank has made payment to such LC Issuer in respect of such
Facility LC pursuant to Section 3.5. Subject to the terms and conditions of this Agreement (including the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions
precedent set forth in Article XI), the Company may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation. 
 3.7 Obligations Absolute. The Company’s obligations under this Article III shall be absolute and unconditional under any and all circumstances and irrespective of any setoff,
counterclaim or defense to payment which the Company may have or have had against any LC Issuer, any Bank or any beneficiary of a Facility LC. The Company further agrees with the LC Issuers and the Banks that the LC Issuers and the Banks shall not
be responsible for, and the Company’s Reimbursement Obligation in respect of any Facility LC shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in
fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Company, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be
transferred or any claims or defenses whatsoever of the Company or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee. Subject to the proviso contained in the first sentence of Section 3.6, no LC
Issuer shall be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC. The Company agrees that any action taken or omitted by any
LC Issuer or any Bank under or in connection with a Facility LC and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon the Company and shall not put any LC Issuer or any Bank under any
liability to the Company. Nothing in this Section 3.7 is intended to limit the right of the Company to make a claim against any LC Issuer for damages as contemplated by the proviso to the first sentence of Section 3.6.

 3.8 Actions of LC Issuers. Each LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any
Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex, teletype or electronic message, statement, order or other document believed by it to be genuine and correct and to have
been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, 

  
 -24-









 
independent accountants and other experts selected by such LC Issuer. Each LC Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first
have received such advice or concurrence of the Majority Banks as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Banks against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action. Notwithstanding any other provision of this Article III, each LC Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance
with a request of the Majority Banks, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Banks and any future holders of a participation in any Facility LC. 

3.9 Indemnification. The Company hereby agrees to indemnify and hold harmless each Bank, each LC Issuer and the Agent, and their
respective directors, officers, agents and employees from and against any and all claims and damages, losses, liabilities, reasonable costs or expenses which such Bank, such LC Issuer or the Agent may incur (or which may be claimed against such
Bank, such LC Issuer or the Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC or any actual or proposed use of any Facility LC,
including any claims, damages, losses, liabilities, costs or expenses which any LC Issuer may incur by reason of or in connection with (i) the failure of any other Bank to fulfill or comply with its obligations to such LC Issuer hereunder (but
nothing herein contained shall affect any rights the Company may have against any Defaulting Bank) or (ii) by reason of or on account of such LC Issuer issuing any Facility LC which specifies that the term “Beneficiary” included
therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to such LC Issuer,
evidencing the appointment of such successor Beneficiary; provided that the Company shall not be required to indemnify any Bank, any LC Issuer or the Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but
only to the extent, caused by (x) the willful misconduct or gross negligence of any LC Issuer in determining whether a request presented under any Facility LC issued by it complied with the terms of such Facility LC or (y) any LC
Issuer’s failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Nothing in this Section 3.9 is intended to limit the
obligations of the Company under any other provision of this Agreement. 
 3.10 Banks’ Indemnification. Each Bank
shall, ratably in accordance with its Pro Rata Share, indemnify each LC Issuer (in such LC Issuer’s capacity as an LC Issuer), its Affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the
Company) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or such LC Issuer’s
failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of the Facility LC) that such indemnitees may suffer or incur in connection with this Article III or
any action taken or omitted by such indemnitees hereunder (in such LC Issuer’s capacity as an LC Issuer). 
 3.11 Rights
as a Bank. In its capacity as a Bank, each LC Issuer shall have the same rights and obligations as any other Bank. 

  
 -25-









 ARTICLE IV 
 CHANGE IN CIRCUMSTANCES 
 4.1 Yield Protection. 

(a) If any Change in Law, 
 (i) subjects any Bank, any LC Issuer or any applicable Lending Installation to any tax, duty, charge, withholding levy, imposts, deduction, assessment or fee on its loans, loan principal, letters of
credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto (other than (A) Taxes, (B) Excluded Taxes, and (C) Other Taxes), or 

(ii) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar
requirement against assets of, deposits with or for the account of, or credit extended by any Bank, any LC Issuer or any applicable Lending Installation (including any reserve costs under Regulation D with respect to Eurocurrency liabilities (as
defined in Regulation D)), or 
 (iii) imposes any other condition the result of which is to increase the cost to
any Bank, any LC Issuer or any applicable Lending Installation of making, funding or maintaining Credit Extensions (including any participations in Facility LCs), or reduces any amount receivable by any Bank, any LC Issuer or any applicable Lending
Installation in connection with Credit Extensions (including any participations in Facility LCs) or requires any Bank, any LC Issuer or any applicable Lending Installation to make any payment calculated by reference to its Outstanding Credit
Exposure or interest received by it, by an amount deemed material by such Bank or such LC Issuer, or 
 (iv)
affects the amount of capital or liquidity required or expected to be maintained by any Bank, any LC Issuer or any applicable Lending Installation or any corporation controlling any Bank or any LC Issuer and such Bank or such LC Issuer, as
applicable, determines the amount of capital or liquidity required is increased by or based upon the existence of this Agreement or its obligation to make Credit Extensions (including any participations in Facility LCs) hereunder or of commitments
of this type, 
 then, upon presentation by such Bank or such LC Issuer to the Company of a certificate (as referred to in the immediately
succeeding sentence of this Section 4.1) setting forth the basis for such determination and the additional amounts reasonably determined by such Bank or such LC Issuer for the period of up to ninety (90) days prior to the date on
which such certificate is delivered to the Company and the Agent, to be sufficient to compensate such Bank or such LC Issuer, as applicable, in light of such circumstances, the Company shall within thirty (30) days of such delivery of such
certificate pay to the Agent for the account of such Bank or such LC Issuer, as applicable, the specified amounts set forth on such certificate. The affected Bank or LC Issuer, as applicable, shall deliver to the Company and the Agent a certificate
setting forth the basis of the claim and specifying in reasonable detail the calculation of such increased expense, which certificate shall be prima facie evidence as to such increase and such amounts.


  
 -26-









 
An affected Bank or LC Issuer, as applicable, may deliver more than one certificate to the Company during the term of this Agreement. In making the determinations contemplated by the
above-referenced certificate, any Bank and any LC Issuer may make such reasonable estimates, assumptions, allocations and the like that such Bank or such LC Issuer, as applicable, in good faith determines to be appropriate, and such Bank’s or
such LC Issuer’s selection thereof in accordance with this Section 4.1 shall be conclusive and binding on the Company, absent manifest error. 
 (b) No Bank or LC Issuer shall be entitled to demand compensation or be compensated hereunder to the extent that such compensation relates to any period of time more than ninety (90) days prior to
the date upon which such Bank or such LC Issuer, as applicable, first notified the Company of the occurrence of the event entitling such Bank or such LC Issuer, as applicable, to such compensation (unless, and to the extent, that any such
compensation so demanded shall relate to the retroactive application of any event so notified to the Company). 
 4.2
Replacement of Banks. 
 (a) If any Bank shall make a demand for payment under
Section 4.1, then within thirty (30) days after such demand, the Company may, with the approval of the Agent and each LC Issuer which has issued a Facility LC which is then outstanding or in respect of which there is any
unreimbursed Reimbursement Obligation (which approvals shall not be unreasonably withheld) and provided that no Default or Event of Default shall then have occurred and be continuing, demand, at the Company’s sole cost and expense, that such
Bank assign to one or more financial institutions designated by the Company and approved by the Agent all (but not less than all) of such Bank’s Commitment and Outstanding Credit Exposure within the period ending on the later of such 30th day and the last day of the longest of the then current Interest
Periods or maturity dates for such Outstanding Credit Exposure. Any such assignment shall be consummated on terms satisfactory to the assigning Bank; provided that such Bank’s consent to such assignment shall not be unreasonably
withheld. 
 (b) If the Company shall elect to replace a Bank pursuant to clause (a) above, the Company shall prepay
the Outstanding Credit Exposure of such Bank, and the financial institution or institutions selected by the Company shall replace such Bank as a Bank hereunder pursuant to an instrument satisfactory to the Company, the Agent and the Bank being
replaced by making Credit Extensions to the Company in the amount of the Outstanding Credit Exposure of such assigning Bank and assuming all the same rights and responsibilities hereunder as such assigning Bank and having the same Commitment as such
assigning Bank. 
 (c) If any Bank becomes a Defaulting Bank, then the Company may, at its sole expense and effort, upon notice
to such Bank and the Agent, require such Bank to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.1), all its interests, rights and obligations under this Agreement to an
assignee that shall assume such obligations (which assignee may be another Bank, if such Bank accepts such assignment); provided that (i) to the extent required pursuant to Section 12.1(c), the Company shall have received the
necessary consents from the Agent and the LC Issuer, if any, and (ii) such Bank shall have received payment of an amount equal to its Outstanding Credit Exposure, accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the 

  
 -27-









 
assignee (to the extent of such Outstanding Credit Exposure and accrued interest and fees) or the Company (in the case of all other amounts). A Bank shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such Bank or otherwise, the circumstances entitling the Company to require such assignment and delegation cease to apply. 

4.3 Availability of Eurodollar Rate Loans. If: 
 (a) any Bank determines that maintenance of a Eurodollar Rate Loan at a suitable Lending Installation would violate any applicable law, rule, regulation or directive, whether or not having the force of
law, or 
 (b) the Majority Banks determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar
Rate Loans are not available or (ii) the Base Eurodollar Rate does not accurately reflect the cost of making or maintaining a Eurodollar Rate Loan, 
 then the Agent shall suspend the availability of Eurodollar Rate Loans and, in the case of clause (a), require any outstanding Eurodollar Rate Loans to be converted to Floating Rate Loans on such
date as is required by the applicable law, rule, regulation or directive. 
 4.4 Funding Indemnification. If any payment
of a Eurodollar Rate Loan occurs on a date which is not the last day of an applicable Interest Period, whether because of prepayment or otherwise, or a Eurodollar Rate Loan is not made on the date specified by the Company for any reason other than
default by the Banks, the Company will indemnify each Bank for any loss or cost (but not lost profits) incurred by it resulting therefrom, including any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar
Rate Loan. 
 4.5 Taxes. 
 (a) All payments by the Company to or for the account of any Bank, any LC Issuer or the Agent hereunder or under any Bond or Facility LC Application shall be made free and clear of and without deduction
for any and all Taxes unless such deduction is required by law. If the Company shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Bank, any LC Issuer or the Agent, (i) the sum payable shall be
increased by the amount of such Taxes required to be withheld as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.5) such Bank, such LC Issuer or the
Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Company shall make such deductions, (iii) the Company shall pay the full amount deducted to the relevant
authority in accordance with applicable law and (iv) the Company shall furnish to the Agent the original copy of a receipt evidencing payment thereof within thirty (30) days after such payment is made. 

(b) In addition, the Company hereby agrees to pay any present or future stamp or documentary taxes and any other excise or property
taxes, charges or similar levies which arise from any payment made hereunder or under any Bond or Facility LC Application or from the execution or delivery of, or otherwise with respect to, this Agreement or any Bond or Facility LC Application
(“Other Taxes”). 

  
 -28-









 (c) The Company hereby agrees to indemnify the Agent, each LC Issuer and each Bank for the
full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed on amounts payable under this Section 4.5) paid by the Agent, such LC Issuer or such Bank and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto. Payments due under this indemnification shall be made within thirty (30) days of the date the Agent, such LC Issuer or such Bank makes demand therefor pursuant to Section 4.6. 

(d) Each Bank that is not incorporated under the laws of the United States of America or a state thereof (each a “Non-U.S.
Bank”) agrees that it will, not more than ten (10) Business Days after the Amendment Effective Date, or, if later, not more than ten (10) Business Days after becoming a Bank hereunder, (i) deliver to each of the Company and
the Agent two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, or any other form or documentation prescribed by applicable law, certifying in either case that such Bank is entitled to receive payments under this
Agreement without deduction or withholding of any United States federal income taxes, and (ii) deliver to each of the Company and the Agent a United States Internal Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to
an exemption from United States backup withholding tax. Each Non-U.S. Bank further undertakes to deliver to each of the Company and the Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such
form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Company or the Agent.
All forms or amendments described in the preceding sentence shall certify that such Bank is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including any
change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Bank from duly completing and delivering any such form
or amendment with respect to it and such Bank advises the Company and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax. 

(e) For any period during which a Non-U.S. Bank has failed to provide the Company with an appropriate form pursuant to clause (d),
above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be
provided), such Non-U.S. Bank shall not be entitled to indemnification under this Section 4.5 with respect to Taxes imposed by the United States; provided that, should a Non-U.S. Bank which is otherwise exempt from or subject to a
reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under clause (d) above, the Company shall take such steps as such Non-U.S. Bank shall reasonably request to assist such Non-U.S.
Bank to recover such Taxes. 
 (f) Any Bank that is entitled to an exemption from or reduction of withholding tax with respect
to payments under this Agreement or any Bond pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Company (with a copy to the Agent), at the time or times prescribed by applicable law, such properly completed and
executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate. 

  
 -29-









 (g) If a payment made to a Bank under this Agreement would be subject to U.S. Federal
withholding tax imposed by FATCA if such Bank were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Bank shall deliver to the Agent,
at the time or times prescribed by law and at such time or times reasonably requested by the Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional
documentation reasonably requested by the Agent as may be necessary for the Agent to comply with its obligations under FATCA, to determine that such Bank has or has not complied with such Bank’s obligations under FATCA and, as necessary, to
determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 4.5(g), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 

(h) Each Bank and each LC Issuer shall severally indemnify the Agent for any taxes, levies, imposts, duties, deductions, withholdings,
assessments, fees or other charges imposed by any taxing authority (but, in the case of any Taxes, only to the extent that the Company has not already indemnified the Agent for such Taxes and without limiting the obligation of the Company to do so)
attributable to such Bank or LC Issuer that are paid or payable by the Agent in connection with this Agreement, any Bond or any Facility LC and any reasonable expenses arising therefrom or with respect thereto, whether or not such amounts were
correctly or legally imposed or asserted by the relevant taxing authority. The indemnity under this Section 4.5(h) shall be paid within ten (10) days after the Agent delivers to the applicable Bank or LC Issuer a certificate stating
the amount so paid or payable by the Agent. Such certificate shall be conclusive of the amount so paid or payable absent manifest error. The obligations of the Banks and LC Issuers under this clause (h) shall survive the payment of the
Obligations and termination of this Agreement. 
 4.6 Bank Certificates, Survival of Indemnity. To the extent reasonably
possible, each Bank shall designate an alternate Lending Installation with respect to Eurodollar Rate Loans to reduce any liability of the Company to such Bank under Section 4.1 or to avoid the unavailability of Eurodollar Rate Loans
under Section 4.3, so long as such designation is not disadvantageous to such Bank. A certificate of such Bank as to the amount due under Section 4.1, 4.4 or 4.5 shall be final, conclusive and binding on the
Company in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Rate Loan shall be calculated as though each Bank funded each Eurodollar Rate Loan through the purchase of a deposit of
the type and maturity corresponding to the deposit used as a reference in determining the Base Eurodollar Rate applicable to such Loan whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in any certificate
shall be payable on demand after receipt by the Company of such certificate. The obligations of the Company under Sections 4.1, 4.4 and 4.5 shall survive payment of the Obligations and termination of this Agreement;
provided that no Bank shall be entitled to compensation to the extent that such compensation relates to any period of time more than ninety (90) days after the termination of this Agreement. 

  
 -30-









 4.7 Defaulting Banks. 

Notwithstanding any provision of this Agreement to the contrary, if any Bank becomes a Defaulting Bank, then the following provisions
shall apply for so long as such Bank is a Defaulting Bank: 
 (a) Commitment Fees shall cease to accrue on the unfunded portion
of the Commitment of such Defaulting Bank pursuant to Section 2.5(a); 
 (b) the Commitment and Outstanding Credit
Exposure of such Defaulting Bank shall not be included in determining whether the Majority Banks have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 10.1); provided,
that this clause (b) shall not apply to the vote of a Defaulting Bank in the case of an amendment, waiver or other modification requiring the consent of such Bank or each Bank affected thereby) 

(c) if any LC Obligations exist at the time a Bank becomes a Defaulting Bank then: 

(i) so long as no Default or Event of Default shall be continuing immediately before or after giving effect to such
reallocation, all or any part of such LC Obligation shall be reallocated among the non-Defaulting Banks in accordance with their respective Pro Rata Share but only to the extent (x) the sum of all non-Defaulting Banks’ Outstanding Credit
Exposure does not exceed the total of all non-Defaulting Banks’ Commitments, (y) no Bank’s Outstanding Credit Exposure shall exceed its Commitment and (z) the conditions set forth in Section 11.2 are satisfied at such
time; 
 (ii) if the reallocation described in subclause (i) above cannot, or can only partially, be
effected, the Company shall within one (1) Business Day following notice by the Agent, cash collateralize for the benefit of the relevant LC Issuer such Defaulting Bank’s Pro Rata Share of the LC Obligations (after giving effect to any
partial reallocation pursuant to subclause (i) above) in accordance with the procedures set forth in Section 9.2 for so long as such LC Obligation is outstanding; 

(iii) if the Company cash collateralizes any portion of such Defaulting Bank’s Pro Rata Share of the LC Obligations
pursuant this clause (c), the Company shall not be required to pay any fees to such Defaulting Bank pursuant to Section 3.4 with respect to such Defaulting Bank’s Pro Rata Share of the LC Obligations during the period such
Defaulting Bank’s Pro Rata Share of the LC Obligations is cash collateralized; 
 (iv) if the non-Defaulting
Banks’ Pro Rata Share of the LC Obligations is reallocated pursuant to this clause (c), then the fees payable to the Banks pursuant to Section 2.5(a) and Section 3.4 shall be adjusted in accordance with such
non-Defaulting Banks’ Pro Rata Shares; or 
 (v) if any Defaulting Bank’s Pro Rata Share of the LC
Obligations is neither reallocated nor cash collateralized pursuant to this clause (c), then, without prejudice to any rights or remedies of any LC Issuer or any Bank hereunder, all fees that otherwise would have been payable to such
Defaulting Bank (solely with respect to the portion of such Defaulting Bank’s Commitment that was utilized by such LC Obligations) and LC Fees payable under Section 3.4 with respect to such Defaulting Bank’s Pro Rata Share of
the LC Obligations shall be payable to the applicable LC Issuer until such Defaulting Bank’s Pro Rata Share of the LC Obligation is cash collateralized and/or reallocated; and 

  
 -31-









 (d) so long as any Bank is a Defaulting Bank, no LC Issuer shall be required to issue or
Modify any Facility LC, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Banks and/or cash collateral will be provided by the Company in accordance with clause (c) above, and
participating interests in any such newly issued or Modified Facility LC shall be allocated among non-Defaulting Banks in a manner consistent with clause(c)(i) above (and Defaulting Banks shall not participate therein). 

(e) If (i) a Bankruptcy Event with respect to a Parent of any Bank shall occur following the date hereof and for so long as such
event shall continue or (ii) any LC Issuer has a good faith belief that any Bank has defaulted in fulfilling its obligations under one or more other agreements in which such Bank commits to extend credit, such LC Issuer shall not be required to
issue, amend or increase any Facility LC, unless such LC Issuer, as the case may be, shall have entered into arrangements with the Company or such Bank, satisfactory to such LC Issuer, as the case may be, to defease any risk to it in respect of such
Bank hereunder. 
 (f) In the event that the Agent, the Company, and each LC Issuer each agrees that a Defaulting Bank has
adequately remedied all matters that caused such Bank to be a Defaulting Bank, then the Banks’ Pro Rata Shares of the LC Obligations shall be readjusted to reflect the inclusion of such Bank’s Commitment and on such date such Bank shall
purchase at par such of the Loans of the other Banks as the Agent shall determine may be necessary in order for such Bank to hold such Loans in accordance with its Pro Rata Share of the Aggregate Commitment; provided, that if the Company cash
collateralized any portion of such Defaulting Bank’s Pro Rata Share of the LC Obligations pursuant to Section 4.7(c), such cash shall be returned to the Company.

 (a) If any Event of Default shall occur and be continuing,
the Agent shall upon the request, or may with the consent, of the Majority Banks, by notice to the Company, (i) declare the Commitments and the obligations and powers of the LC Issuers to issue Facility LCs to be terminated or suspended,
whereupon the same shall forthwith terminate, and/or (ii) declare the Obligations to be forthwith due and payable, whereupon the Aggregate Outstanding Credit Exposure and all other Obligations shall become and be forthwith due and payable,
and/or (iii) in addition to the continuing right to demand payment of all amounts payable under this Agreement, make demand on the Company to pay, and the Company will, forthwith upon such demand and without any further notice or act, pay to
the Agent the Collateral Shortfall Amount (as defined below), which funds shall be deposited in the Facility LC Collateral Account, in each case without presentment, demand, protest or further notice of any kind, all of which are hereby expressly
waived by the Company; provided that in the case of an Event of Default referred to in Section 9.1(e), the Commitments shall automatically terminate, the obligations and powers of the LC Issuers to issue Facility LCs shall
automatically terminate and the Obligations shall automatically become due and payable without notice, presentment, demand, protest or other formalities of any kind, all of which are hereby expressly waived by the Company, and the Company will be
and become thereby unconditionally obligated, without any further notice, act or demand, to pay to the Agent an amount in immediately available funds, which funds shall be held in the Facility LC Collateral Account, equal to the difference of
(x) the amount of LC Obligations at such time, less (y) the amount on deposit in the Facility LC Collateral Account at such time which is free and clear of all rights and claims of third parties and has not been applied against the
Obligations (such difference, the “Collateral Shortfall Amount”). 
 (b) If at any time while any Event of
Default is continuing, the Agent determines that the Collateral Shortfall Amount at such time is greater than zero, the Agent may make demand on the Company to pay, and the Company will, forthwith upon such demand and without any further notice or
act, pay to the Agent the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account. 

(c) The Agent may, at any time or from time to time after funds are deposited in the Facility LC Collateral Account, apply such funds to
the payment of the Obligations and any other amounts as shall from time to time have become due and payable by the Company to the Banks or the LC Issuers under the Credit Documents. The Company hereby pledges, assigns and grants to the Agent, on
behalf of and for the ratable benefit of the Banks and the LC Issuers, a security interest in all of the Company’s right, title and interest in and to all funds which may from time to time be on deposit in the Facility LC Collateral Account to
secure the prompt and complete payment and performance of the Obligations. The Agent will invest any funds on deposit from time to time in the Facility LC Collateral Account in certificates of deposit of Union Bank having a maturity not exceeding
thirty (30) days. 

  
 -42-









 (d) At any time while any Event of Default is continuing, neither the Company nor any Person
claiming on behalf of or through the Company shall have any right to withdraw any of the funds held in the Facility LC Collateral Account. After all of the Obligations have been indefeasibly paid in full, all Facility LCs have expired or been
terminated and the Aggregate Commitment has been terminated, any funds remaining in the Facility LC Collateral Account shall be returned by the Agent to the Company or paid to whomever may be legally entitled thereto at such time. 

ARTICLE X 

WAIVERS, AMENDMENTS AND REMEDIES

any manner the rights of the Banks or the Company hereunder or waiving any Event of Default hereunder; provided that no such supplemental agreement shall, without the consent of all of the Banks: 

(a) Extend the maturity of any Loan or reduce the principal amount thereof, or extend the expiry date of any Facility LC to a date after
the scheduled Termination Date, or reduce the rate or extend the time of payment of interest thereon or fees thereon or Reimbursement Obligations related thereto.

 (c)
Extend the Termination Date or increase the amount of the Commitment of any Bank hereunder or the commitment to issue Facility LCs, or permit the Company to assign its rights under this Agreement.

Agent, the LC Issuer, if applicable, and the Majority Banks. 

  
 -43-









 10.2 Preservation of Rights. No delay or omission of the Banks, the LC Issuers or the
Agent to exercise any right under the Credit Documents shall impair such right or be construed to be a waiver of any Default or Event of Default or an acquiescence therein, and the making of a Credit Extension notwithstanding the existence of a
Default or Event of Default or the inability of the Company to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or
further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Credit Documents whatsoever shall be valid unless in writing signed by the Banks required pursuant
to Section 10.1, and then only to the extent in such writing specifically set forth. All remedies contained in the Credit Documents or by law afforded shall be cumulative and all shall be available to the Agent, the LC Issuers and the
Banks until the Obligations have been paid in full.

 ARTICLE XII 
 GENERAL PROVISIONS 
 12.1 Successors and Assigns. (a) The terms
and provisions of the Credit Documents shall be binding upon and inure to the benefit of the Company and the Banks and their respective successors and assigns, except that the Company shall not have the right to assign its rights under the Credit
Documents. Any Bank may sell participations in all or a portion of its rights and obligations under this Agreement pursuant to clause (b) below and any Bank may assign all or any part of its rights and obligations under this Agreement
pursuant to clause (c) below. 
 (b) Any Bank may sell participations to one or more banks or other entities (other
than the Company and its Affiliates) (each a “Participant”) in all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and its Outstanding Credit Exposure); provided
that (i) such Bank’s obligations under this Agreement (including its Commitment to the Company hereunder) shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such
obligations, (iii) such Bank shall remain the holder of the Outstanding Credit Exposure of such Bank for all purposes of this Agreement and (iv) the Company shall continue to deal solely and directly with such Bank in connection with such
Bank’s rights and obligations under this Agreement. Each Bank shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Credit Documents other than any
amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest which would require consent of all of the Banks pursuant to the terms of Section 10.1 or of any other Credit Document. The
Company agrees that each Participant shall be deemed to have the right of setoff provided in Section 12.10 in respect of its participating interest in amounts owing under the Credit Documents to the same extent as if the amount of its
participating interest were owing directly to it as a Bank under the Credit Documents; provided that each Bank shall retain the right of setoff provided in Section 12.10 with respect to the amount of participating interests sold
to each Participant. The Banks agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 12.10, agrees to share with each Bank, any amount received pursuant to the exercise of its
right of setoff, such amounts to be shared in accordance with Section 12.11 as if each Participant were a Bank. The Company further agrees that each Participant shall be entitled to the benefits of Sections 4.1, 4.3,
4.4 and 4.5 to the same extent as if it were a Bank and had acquired its interest by assignment pursuant to Section 12.1(c); provided that (i) a Participant shall not be entitled to receive any greater payment
under Section 4.1, 4.3, 4.4 or 4.5 than the Bank that sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to
such Participant is made with the prior written consent of the Company, and (ii) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of
Section 4.5 to the same extent as if it were a Bank (it being understood that the documentation required under Section 4.5 shall be delivered to the participating Bank). Each Bank that sells a participation shall, acting
solely for this purpose as a non-fiduciary agent of the Company, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the obligations
under this Agreement (the “Participant Register”); provided that no Bank shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any
information relating to a Participant’s interest in the obligations under this 

  
 -46-









 
Agreement) except to the extent that such disclosure is necessary to establish that such interest is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations.
The entries in the Participant Register shall be conclusive absent manifest error, and such Bank shall treat each person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement
notwithstanding any notice to the contrary. 
 (c) Any Bank may, in the ordinary course of its business and in accordance with
applicable law, at any time assign to one or more financial institutions or other Persons (other than the Company and its Affiliates) all or any part of its rights and obligations under this Agreement; provided that (i) unless such
assignment is to another Bank, an Affiliate of such assigning Bank, or any direct or indirect contractual counterparty in any swap agreement relating to the Loans to the extent required in connection with the settlement of such Bank’s
obligations pursuant thereto, such Bank has received the prior written consent of the Agent, the Company (so long as no Event of Default exists) and each LC Issuer, which consents of the Agent and the Company shall not be unreasonably withheld or
delayed, provided that the Company shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Agent within ten (10) Business Days after having received notice thereof, and (ii) the
minimum principal amount of any such assignment (other than assignments to a Federal Reserve Bank, to another Bank, to an Affiliate of such assigning Bank or any direct or indirect contractual counterparty in any swap agreement relating to the Loans
to the extent required in connection with the settlement of such Bank’s obligations pursuant thereto) shall be $5,000,000 (or such lesser amount consented to by the Agent and, so long as no Event of Default shall be continuing, the Company,
which consents shall not be unreasonably withheld or delayed); provided that after giving effect to such assignment the assigning Bank shall have a Commitment of not less than $5,000,000 (unless otherwise consented to by the Agent and, so
long as no Event of Default shall be continuing, the Company), unless such assignment constitutes an assignment of all of the assigning Bank’s Commitment, Loans and other rights and obligations hereunder to a single assignee. Notwithstanding
the foregoing sentence, (x) any Bank may at any time, without the consent of the Company, any LC Issuer or the Agent, pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such
Bank, including, without limitation, any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such assignment shall release the transferor Bank from its obligations hereunder or substitute any such pledgee or
assignee for such Bank as a party hereto; and (y) no assignment by a Bank to any Affiliate of such Bank shall release such Bank from its obligations hereunder unless (I) the Agent and, so long as no Event of Default exists, the Company
have approved such assignment or (II) the creditworthiness of such Affiliate (as determined in accordance with customary standards of the banking industry) is no less than that of the assigning Bank. 

(d) Any Bank may, in connection with any sale or participation or proposed sale or participation pursuant to this
Section 12.1, disclose to the purchaser or participant or proposed purchaser or participant any information relating to the Company furnished to such Bank by or on behalf of the Company; provided that prior to any such disclosure
of non-public information, the purchaser or participant or proposed purchaser or participant (which purchaser or participant is not an Affiliate of a Bank) shall agree to preserve the confidentiality of any confidential information (except any such
disclosure as may be required by law or regulatory process) relating to the Company received by it from such Bank. 

  
 -47-









 (e) Assignments under this Section 12.1 shall be made pursuant to an agreement
(an “Assignment Agreement”) substantially in the form of Exhibit C hereto or in such other form as may be agreed to by the parties thereto and shall not be effective until a $3,500 fee has been paid to the Agent by the
assignee, which fee shall cover the cost of processing such assignment; provided that such fee shall not be incurred in the event of an assignment by any Bank of all or a portion of its rights under this Agreement to (i) a Federal
Reserve Bank, (ii) a Bank or an Affiliate of the assigning Bank or (iii) any direct or indirect contractual counterparty in any swap agreement relating to the Loans to the extent required in connection with the settlement of such
Bank’s obligations pursuant thereto. The Agent, acting for this purpose as a non-fiduciary agent of the Company, shall maintain at one of its offices a copy of each Assignment Agreement delivered to it and a register for the recordation of the
names and addresses of the Banks, and the Commitment of, and principal amount of the Loans, Bonds, and Facility LCs owing to, each Bank pursuant to the terms hereof from time to time (the “Register”). The entries in the Register
shall be conclusive and the Company, the Agent, the LC Issuers and the Banks shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary. The Register shall be available for inspection by the Company, any LC Issuer, and any Bank at any reasonable time and from time to time upon reasonable prior notice. 

12.2 Survival of Representations. All representations and warranties of the Company contained in this Agreement shall survive the
making of the Credit Extensions herein contemplated. 
 12.3 Governmental Regulation. Anything contained in this
Agreement to the contrary notwithstanding, no LC Issuer or Bank shall be obligated to extend credit to the Company in violation of any limitation or prohibition provided by any applicable statute or regulation. 

12.4 Taxes. Any taxes (excluding income taxes) payable or ruled payable by any Federal or State authority in respect of the
execution of the Credit Documents shall be paid by the Company, together with interest and penalties, if any. 
 12.5 Choice
of Law. THE CREDIT DOCUMENTS SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS (INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF NEW YORK, BUT OTHERWISE WITHOUT REGARD TO THE LAW OF CONFLICTS) OF THE STATE OF
NEW YORK, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS. THE COMPANY HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR NEW YORK STATE COURT SITTING IN NEW YORK, NEW YORK IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT AND THE COMPANY HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT. EACH OF THE COMPANY, THE AGENT, THE LC
ISSUERS AND THE BANKS HEREBY WAIVES ANY RIGHT TO A JURY TRIAL IN ANY ACTION OR ARISING HEREUNDER OR UNDER ANY CREDIT DOCUMENT. 

12.6 Headings. Section headings in the Credit Documents are for convenience of reference only, and shall not govern the
interpretation of any of the provisions of the Credit Documents. 

  
 -48-









 12.7 Entire Agreement. The Credit Documents embody the entire agreement and
understanding between the Company, the LC Issuers, the Agent and the Banks and supersede all prior agreements and understandings between the Company, the LC Issuers, the Agent and the Banks relating to the subject matter thereof. 

12.8 Expenses; Indemnification. The Company shall reimburse the Agent and the Arranger for (a) any reasonable costs, internal

Affiliates, and the directors, officers, employees and agents of the foregoing (all of the foregoing, the “Indemnified Persons), against all losses, claims, damages, penalties, judgments, liabilities and reasonable expenses (including
all reasonable expenses of litigation or preparation therefor whether or not an Indemnified Person is a party thereto), regardless of whether such matter is initiated by a third party or by the Company or any of its Affiliates or equityholders,

Any provision in any Credit Document that is held to be inoperative, unenforceable or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable or invalid without affecting the remaining provisions in that
jurisdiction or the operation, enforceability or validity of that provision in any other jurisdiction, and to this end the provisions of all Credit Documents are declared to be severable.

 12.10 Setoff. In addition to, and without limitation of, any rights of the Banks
under applicable law, if the Company becomes insolvent, however evidenced, or during the continuance of an Event of Default, any indebtedness from any Bank or any of its Affiliates to the Company (including all account balances, whether provisional
or final and whether or not collected or available) may be, upon prior notice to the Agent, offset and applied toward the payment of the Obligations owing to such Bank or such Affiliate, whether or not the Obligations, or any part hereof, shall then
be due. The Company agrees that any purchaser or participant under Section 12.1 may, to the fullest extent permitted by law and in accordance with this Agreement, exercise all its rights of payment with respect to such purchase or
participation as if it were the direct creditor of the Company in the amount of such purchase or participation. 
 12.11
Ratable Payments. If any Bank, whether by setoff or otherwise, has payment made to it upon its Outstanding Credit Exposure in a greater proportion than that received by any other Bank, such Bank agrees, promptly upon demand, to purchase a
portion of the Aggregate Outstanding Credit Exposure held by the other Banks so that after such purchase each Bank will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. If any Bank, whether in connection with setoff or amounts
which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Bank agrees, promptly upon demand, to take such action necessary such that all Banks
share in the benefits of such collateral ratably in proportion to their respective Pro Rata Share of the Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments
shall be made. 
 12.12 Nonliability. The relationship between the Company, on the one hand, and the Banks, the Arranger,
the LC Issuers and the Agent, on the other hand, shall be solely that of borrower and lender. None of the Agent, the Arranger, any LC Issuer or any Bank shall have any fiduciary responsibilities to the Company. To the fullest extent permitted by
law, the Company hereby waives and releases any claims that it may have against each of the Agent, the Arrangers, each LC Issuer and each Bank with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of
any transaction contemplated hereby. None of the Agent, the Arranger, any LC Issuer or any Bank undertakes any responsibility to the Company to review or inform the Company of any matter in connection with any phase of the Company’s business or
operations. The Company shall rely entirely upon its own judgment with respect to its business, and any review, inspection, supervision or information supplied to the Company by the Banks is for the protection of the Banks and neither the Company
nor any third party is entitled to rely thereon. The Company agrees that none of the Agent, the Arranger, any LC Issuer or any Bank shall have liability to the Company (whether sounding in tort, contract or otherwise) for losses suffered by the
Company in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Credit Documents, or any act, omission or event occurring in connection therewith, unless it is determined in
a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. None of the Agent, the Arranger, any LC Issuer or any Bank
shall have any liability with respect to, and the Company hereby waives, releases and agrees not to sue for, any special, indirect, consequential or punitive damages suffered by the Company in connection with, arising out of, or in any way related
to the Credit Documents or the transactions contemplated thereby.

 12.13 Other Agents. The Banks identified on the signature pages of this Agreement or
otherwise herein, or in any amendment hereof or other document related hereto, as being a “Co-Syndication Agent” or the “Documentation Agent” (the “Other Agents”) shall have no rights, powers, obligations,
liabilities, responsibilities or duties under this Agreement other than those applicable to all Banks as such. Without limiting the foregoing, the Other Agents shall not have or be deemed to have any fiduciary relationship with any Bank. Each Bank
acknowledges that it has not relied, and will not rely, on the Other Agents in deciding to enter into this Agreement or in taking or refraining from taking any action hereunder or pursuant hereto. Nothing contained in this Agreement or otherwise
shall be construed to impose any obligation or duty on any Other Agent, other than those applicable to all Banks as such. 

12.14 USA Patriot Act. Each Bank hereby notifies the Company that pursuant to requirements of the USA Patriot Act, such Bank is
required to obtain, verify and record information that identifies the Company, which information includes the name and address of the Company and other information that will allow such Bank to identify the Company in accordance with the USA Patriot
Act. 
 12.15 Electronic Delivery. 
 (a) The Company shall use its commercially reasonable best efforts to transmit to the Agent all information, documents and other materials that it is obligated to furnish to the Agent pursuant to this
Agreement and the other Credit Documents, including all notices, requests, financial statements, financial and other reports, certificates and other information materials, but excluding (i) any Borrowing Notice, Conversion/Continuation Notice
or notice of prepayment, (ii) any notice of a Default or an Event of Default or (iii) any communication that is required to be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or any Advance hereunder
(all such non-excluded communications, collectively, “Communications”), in an electronic/soft medium in a format reasonably acceptable to the Agent to such e-mail address as designated by the Agent from time to time. In addition,
the Company shall continue to provide Communications to the Agent or any Bank in the manner specified in this Agreement but only to the extent requested by the Agent or such Bank. Each Bank and the Company further agrees that the Agent may make
Communications available to the Banks by posting Communications on IntraLinks or a substantially similar electronic transmission system (the “Platform”); provided, that upon written notice to the Agent and the Company, any
Bank (such bank, a “Declining Bank”) may decline to receive Communications via the Platform and shall direct the Company to provide, and the Company shall so provide, such Communications to such Declining Bank by delivery to such
Declining Bank’s address in accordance with Section 14.1. Subject to the conditions set forth in the proviso in the immediately preceding sentence, nothing in this Section 12.15 shall prejudice the right of the Agent to
make Communications available to the Banks in any other manner specified herein. 
 (b) Each Bank (other than a Declining Bank)
agrees that an e-mail notice to it (at the address provided pursuant to the next sentence and deemed delivered as provided in clause (c) below) specifying that a Communication has been posted to the Platform shall constitute effective
delivery of such Communication to such Bank for purposes of this Agreement. Each Bank (other than a Declining Bank) agrees (i) to notify the Agent in writing (including by electronic communication) from time to time to ensure that the Agent has
on record an effective e-mail address for such Bank to which the foregoing notice may be sent by electronic transmission and (ii) that the foregoing notice may be sent to such e-mail address. 

  
 -51-









 (c) Each party hereto (other than a Declining Bank) agrees that any electronic Communication
referred to in this Section 12.15 shall be deemed delivered upon the posting of a record of such Communication as “sent” in the e-mail system of the sending party or, in the case of any such Communication to the Agent, upon the
posting of a record of such Communication as “received” in the e-mail system of the Agent, provided that if such Communication is not so received by a Person during the normal business hours of such Person, such Communication shall
be deemed delivered at the opening of business on the next business day for such Person. 
 (d) Each party hereto acknowledges
that the distribution of material through an electronic medium is not necessarily secure and there are confidentiality and other risks associated with such distribution. 
 (e) EACH PARTY HERETO FURTHER ACKNOWLEDGES AND AGREES THAT: 
 (i)
NONE OF THE AGENT OR ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (COLLECTIVELY, THE “AGENT PARTIES”) WARRANTS THE ADEQUACY OF THE PLATFORM OR THE ACCURACY OR
COMPLETENESS OF ANY COMMUNICATION, AND EACH AGENT PARTY EXPRESSLY DISCLAIMS LIABILITY FOR ERRORS OR OMISSIONS IN ANY COMMUNICATION; AND 
 (ii) NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR
OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH ANY COMMUNICATION OR THE PLATFORM. 
 12.16 Amendment and
Restatement. The amendment and restatement of the Existing Credit Agreement pursuant to this Agreement shall be effective as of the Amendment Effective Date, subject to the satisfaction of the conditions precedent set forth in
Section 11.1. This Agreement shall amend and restate in its entirety the Existing Credit Agreement and shall have the effect of a substitution of terms of the Existing Credit Agreement, but this Agreement will not have the effect of
causing a novation, refinancing or other repayment of the Original Obligations or a termination or extinguishment of the Liens securing such Original Obligations, which Original Obligations shall remain outstanding and repayable pursuant to the
terms of this Agreement and which Liens shall remain attached, enforceable and perfected securing such Original Obligations and all additional obligations arising under this Agreement. Each reference to the Existing Credit Agreement in any of the
Credit Documents, or any other document, instrument or agreement delivered in connection therewith, shall mean and be a reference to this Agreement. 

  
 -52-









 12.17 Confidentiality. Each of the Agent, the LC Issuers and the Banks agrees to
maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors
(it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority
or self-regulatory body, (c) to the extent required by applicable laws or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to
(i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative
transaction relating to the Company and its obligations or (iii) any actual or prospective credit insurance provider relating to the Company and its obligations, or (g) to the extent such Information (i) becomes publicly available
other than as a result of a breach of this Section or (ii) becomes available to the Agent, any LC Issuer or any Bank on a non-confidential basis from a source other than the Company. For the purposes of this Section, “Information”
means all information received from the Company relating to the Company, its Subsidiaries or their business, other than any such information that is available to the Agent, any LC Issuer or any Bank on a non-confidential basis prior to disclosure by
the Company; provided that, in the case of information received from the Company after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of
Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own
confidential information. 
 ARTICLE XIII 
 THE AGENT 
 13.1 Appointment. Union Bank is hereby appointed Agent
hereunder, and each of the Banks irrevocably authorizes the Agent to act as the contractual representative on behalf of such Bank. The Agent agrees to act as such upon the express conditions contained in this Article XIII. The Agent shall not
have a fiduciary relationship in respect of any Bank by reason of this Agreement nor shall the Agent have any implied duties, regardless of whether a Default or Event of Default has occurred and is continuing. 

13.2 Powers. The Agent shall have and may exercise such powers hereunder as are specifically delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental thereto. The Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until written notice thereof is given to the Agent by the Company or a Bank or any
implied duties to the Banks or any obligation to the Banks to take any action hereunder (whether a Default or Event of Default has occurred and is continuing), except any action specifically provided by this Agreement to be taken by the Agent.

 13.3 General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to
the Banks or any Bank for any action taken or omitted to be taken by it or them hereunder or in connection herewith except for its or their own gross negligence or willful misconduct. 

  
 -53-









 13.4 No Responsibility for Recitals, Etc. The Agent shall not be responsible to the
Banks for any recitals, reports, statements, warranties or representations herein or in any Credit Document or be bound to ascertain or inquire as to the performance or observance of any of the terms of this Agreement. 

13.5 Action on Instructions of Banks. The Agent shall in all cases be fully protected in acting, or in refraining from acting,
hereunder and under any other Credit Document in accordance with written instructions signed by the Majority Banks (or all of the Banks if required by Section 10.1), and such instructions and any action taken or failure to act pursuant
thereto shall be binding on all of the Banks. The Banks hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Credit Document
unless it shall be requested in writing to do so by the Majority Banks. The Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Credit Document unless it shall first be indemnified to its
satisfaction by the Banks pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action. 
 13.6 Employment of Agents and Counsel. The Agent may execute any of its duties as Agent hereunder by or through employees, agents and attorneys-in-fact and shall not be answerable to the Banks,
except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of counsel concerning all
matters pertaining to the agency hereby created and its duties hereunder. 
 13.7 Reliance on Documents; Counsel. The
Agent shall be entitled to rely upon any notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in
respect to legal matters, upon the opinion of counsel selected by the Agent, which counsel may be employees of the Agent. 

13.8 Agent’s Reimbursement and Indemnification. The Banks agree to reimburse and indemnify the Agent (in the Agent’s
capacity as Agent) ratably in accordance with their respective Pro Rata Shares (i) for any amounts not reimbursed by the Company for which the Agent (in the Agent’s capacity as Agent) is entitled to reimbursement by the Company under the
Credit Documents, (ii) for any other expenses reasonably incurred by the Agent on behalf of the Banks, in connection with the preparation, execution, delivery, administration and enforcement of the Credit Documents, and for which the Agent (in
the Agent’s capacity as Agent) is not entitled to reimbursement by the Company under the Credit Documents, and (iii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, reasonable expenses or
disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of this Agreement or any other document delivered in connection with this Agreement or the
transactions contemplated hereby or the enforcement of any of the terms hereof or of any such other documents, and for which the Agent is not entitled to reimbursement by the Company under the Credit Documents; provided that no Bank shall be
liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Agent. 

  
 -54-









 13.9 Rights as a Bank. With respect to its Commitment and any Credit Extension made
by it, the Agent shall have the same rights and powers hereunder as any Bank and may exercise the same as though it were not the Agent, and the term “Bank” or “Banks” shall, unless the context otherwise indicates, include Union
Bank in its individual capacity. The Agent may accept deposits from, lend money to, and generally engage in any kind of banking or trust business with the Company or any Subsidiary as if it were not the Agent. 

13.10 Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon the Agent or any other
Bank and based on the financial statements prepared by the Company and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it
will, independently and without reliance upon the Agent or any other Bank 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. 
 (a) Without limiting clause (a) above, each Bank acknowledges and agrees that neither such Bank nor
any of its Affiliates, participants or assignees may rely on the Agent to carry out such Bank’s or other Person’s customer identification program, or other obligations required or imposed under or pursuant to the USA Patriot Act or the
regulations thereunder, including the regulations contained in 31 C.F.R. 103.121 (as amended or replaced, the “CIP Regulations”), or any other applicable law, rule, regulation or order of any governmental authority, including any
program involving any of the following items relating to or in connection with the Company or any of its Subsidiaries or Affiliates or agents, the Credit Documents or the transactions contemplated hereby: (i) any identity verification
procedure; (ii) any recordkeeping; (iii) any comparison with a government list; (iv) any customer notice or (v) any other procedure required under the CIP Regulations or such other law, rule, regulation or order. 

(b) Within ten (10) days after the date of this Agreement and at such other times as are required under the USA Patriot Act, each
Bank and each assignee and participant that is not incorporated under the laws of the United States of America or a state thereof (and is not excepted from the certification requirement contained in Section 313 of the USA Patriot Act and the
applicable regulations because it is both (i) an Affiliate of a depository institution or foreign bank that maintains a physical presence in the United States or foreign country and (ii) subject to supervision by a banking authority
regulating such affiliated depository institution or foreign bank) shall deliver to the Agent a certification, or, if applicable, recertification, certifying that such Bank is not a “shell” and certifying as to other matters as required by
Section 313 of the USA Patriot Act and the applicable regulations. 
 13.11 Successor Agent. Subject to the
appointment and acceptance of a successor Agent as provided in this paragraph, the Agent may resign at any time by notifying the Banks, the LC Issuers and the Company. Upon any such resignation, the Majority Banks shall have the right, in
consultation with the Company, to appoint a successor. If no successor shall have been so appointed by the Majority Banks and shall have accepted such appointment within thirty (30)

  
 -55-









 
days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Banks and the LC Issuers, appoint a successor Agent which shall be a bank with an
office in the United States, or an Affiliate of any such bank. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Company to a successor Agent shall be in the same amount as those payable to its predecessor (without duplication for
amounts payable to the retiring Agent for the period it was acting as Agent) unless otherwise agreed between the Company and such successor. After the Agent’s resignation hereunder, the provisions of this Article and Section 12.8 shall
continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Agent. 

13.12 Agent and Arranger Fees. The Company agrees to pay to the Agent and the Arranger, for their respective accounts, the fees
agreed to by the Company, the Agent and the Arranger pursuant to the proposal letter agreement, dated as of February 27, 2012 (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Proposal
Letter”), or as otherwise agreed from time to time.

 EXHIBIT A 
 REQUIRED OPINIONS FROM 
 KIMBERLY C. WILSON, ESQ. 

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Michigan.

 2. The execution and delivery of the Credit Documents by the Company and the performance by the Company of the Obligations
have been duly authorized by all necessary corporate action and proceedings on the part of the Company and will not: 
 (a) contravene the Company’s Restated Articles of Incorporation, as amended, or bylaws; 
 (b) contravene any law or any contractual restriction imposed by any indenture or any other agreement or instrument evidencing or governing indebtedness for borrowed money of the Company (including but
not limited to the Company Indentures (as defined below)); or 
 (c) result in or require the creation of any
Lien upon or with respect to any of the Company’s properties except the lien of the Indenture securing the Bonds and any Lien in favor of the Agent on the Facility LC Collateral Account or any funds therein. 

As used in this paragraph 2, “Company Indentures” means collectively, (i) the Indenture dated as of January 1, 1996,
as supplemented and amended from time to time, between the Company (formerly known as Consumers Power Company) and The Bank of New York Mellon (formerly known as The Bank of New York), as Trustee, and (ii) the Indenture dated as of
February 1, 1998, as supplemented and amended from time to time, between the Company and The Bank of New York Mellon (successor trustee to JPMorgan Chase Bank, N.A.), as Trustee. 

3. The Credit Documents have been duly executed and delivered by the Company. 

4. To the best of my knowledge, there is no pending or threatened action or proceeding against the Company or any of its Consolidated
Subsidiaries before any court, governmental agency or arbitrator (except (i) to the extent described in the Company’s annual report on Form 10-K for the year ended December 31, 2011 as filed with the SEC, and (ii) such other
similar actions, suits and proceedings predicated on the occurrence of the same events giving rise to any actions, suits and proceedings described in the reports filed with the SEC set forth in clause (i) of this paragraph 4) which might
reasonably be expected to materially adversely affect the financial condition or results of operations of the Company and its Consolidated Subsidiaries, taken as a whole, or that would materially adversely affect the Company’s ability to
perform its obligations under any Credit Document. To the best of my knowledge, there is no litigation challenging the validity or the enforceability of any of the Credit Documents. 

  
 A-1









 5. No authorization or approval or other action by, and no notice to or filing with, any
governmental authority or regulatory body is required for the due execution, delivery and performance by the Company of any Credit Document, except for the authorization to issue, sell or guarantee secured and/or unsecured long-term debt granted by
the Federal Energy Regulatory Commission in Docket No. ES10-34-000 and in Docket No. ES10-34-001 (hereinafter the “FERC Order”). The FERC Order is in full force and effect as of the date hereof. 

6. The Bonds executed in connection with the Original Credit Agreement (a) are in due and proper form, (b) evidence and secure
the Obligations owing under the Credit Agreement and (c) are valid and enforceable obligations of the Company in accordance with their terms, secured by the lien of the Indenture on an equal and ratable basis with all other bonds issued
thereunder and otherwise entitled to the benefits provided by the Indenture. 
 7. The Indenture has been qualified under the
Trust Indenture Act of 1939, as amended, and the execution and delivery of the Supplemental Indenture will not cause the Indenture to not be so qualified. 
 8. The Company is not an “investment company” or a company “controlled” by an “investment company” as such terms are defined in the Investment Company Act of 1940, as
amended. 
 9. In a properly presented case, a Michigan court or a federal court applying Michigan choice of law rules should
give effect to the choice of law provisions of the Agreement and should hold that the Agreement is to be governed by the laws of the State of New York rather than the laws of the State of Michigan, except in the case of those provisions set forth in
the Agreement the enforcement of which would contravene a fundamental policy of the State of Michigan. In the course of our review of the Agreement, nothing has come to my attention to indicate that any of such provisions would do so.
Notwithstanding the foregoing, even if a Michigan court or a federal court holds that the Agreement is to be governed by the laws of the State of Michigan, the Agreement constitutes a legal, valid and binding obligation of the Company, enforceable
under Michigan law (including usury provisions) against the Company in accordance with its terms, subject to (a) the effect of applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of
creditors’ rights generally and (b) the application of general principles of equity (regardless of whether considered in a proceeding in equity or at law).

a dissolution, winding up, liquidation or reorganization for the purposes of this Section     .3 if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the
conditions stated such in Article     . 
 Section     .4.

trustee in bankruptcy, liquidating trustee or agent or other Person making such payment or distribution to the Trustee or the Holders of Subordinated Securities, for the purposes of ascertaining the Persons entitled to participate in such
distribution, the holders of the Senior Indebtedness and other indebtedness of the Issuer, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article
    . 
 Nothing contained in this Article      or elsewhere in this
Indenture or in any Subordinated Security is intended to or shall affect the obligation of the Issuer to make, or prevent the Issuer from making, at any time except during the pendency of any dissolution, winding up, liquidation or reorganization
proceeding, and, except as provided in subsections (a) and (b) of Section     .2, payments at any time of the principal of, or interest on, Subordinated Securities. 

Section     .6. Trustee Entitled to Assume Payments Not Prohibited in Absence of Notice. The Issuer
shall give prompt written notice to the Trustee of any fact known to the Issuer which would prohibit the making of any payment or distribution to or by the Trustee in respect of the Subordinated Securities. Notwithstanding the provisions of this
Article      or any provision of this Indenture, the Trustee shall not at any time be charged with knowledge of the existence of any facts which would prohibit the making of any payment or distribution to or by the
Trustee, unless at least two Business Days prior to the making of any such payment, the Trustee shall have received written notice thereof from the Issuer or from one or more holders of Senior Indebtedness or from any representative thereof or from
any trustee therefor, together with proof satisfactory to the Trustee of such holding of Senior Indebtedness or of the authority of such representative or trustee; and, prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Sections      and     , shall be entitled to assume conclusively that no such facts exist. The Trustee shall be entitled to rely on the delivery to it of a written notice by a
Person representing himself to be a holder of Senior Indebtedness (or a representative or trustee on behalf of the holder) to establish that such notice has been given by a holder of Senior Indebtedness (or a representative of or trustee on behalf
of any such holder). In the event that the Trustee determines, in good faith, that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payments or distribution pursuant of
this Article     , the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, as to the extent to which such Person is
entitled to participate in such payment or distribution, and as to other facts pertinent to the rights of such Person under this Article     , and if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to receive such payment. The Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and nothing in this Article
     shall apply to claims of, or payments to, the Trustee under or pursuant to Section     . 
 Section     .7. Application by Trustee of Monies or Government Obligations Deposited with It. Money or Government Obligations deposited in trust with the Trustee pursuant
to and in accordance with Section      shall be for the sole benefit of Securityholders and, to the extent allocated for the payment of Subordinated Securities, shall not be subject to the subordination


  
 D-5









 
provisions of this Article     , if the same are deposited in trust prior to the happening of any event specified in Section     .2.
Otherwise, any deposit of monies or Government Obligations by the Issuer with the Trustee or any paying agent (whether or not in trust) for the payment of the principal of, or interest on, any Subordinated Securities shall be subject to the
provisions of Section     .1,     .2 and     .3 except that, if prior to the date on which by the terms of this Indenture any such monies may become payable for any
purposes (including, without limitation, the payment of the principal of, or the interest, if any, on any Subordinated Security) the Trustee shall not have received with respect to such monies the notice provided for in Section
    .6, then the Trustee or the paying agent shall have full power and authority to receive such monies and Government Obligations and to apply the same to the purpose for which they were received, and shall not be
affected by any notice to the contrary which may be received by it on or after such date. This Section     .7 shall be construed solely for the benefit of the Trustee and paying agent and, as to the first sentence hereof,
the Securityholders, and shall not otherwise effect the rights of holders of Senior Indebtedness. 
 Section
    .8. Subordination Rights Not Impaired by Acts or Omissions of Issuer or Holders of Senior Indebtedness. No rights of any present or future holders of any Senior Indebtedness to enforce subordination as provided
herein shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Issuer or by any act or failure to act, in good faith, by any such holders or by any noncompliance by the Issuer with the terms of this
Indenture, regardless of any knowledge thereof which any such holder may have or be otherwise charged with. 
 Without in any
way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness of the Issuer may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Subordinated Securities, without
incurring responsibility to the Holders of the Subordinated Securities and without impairing or releasing the subordination provided in this Article      or the obligations hereunder of the Holders of the Subordinated
Securities to the holders of such Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, such Senior Indebtedness, or otherwise amend or
supplement in any manner such Senior Indebtedness or any instrument evidencing the same or any agreement under which such Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing such Senior Indebtedness; (iii) release any Person liable in any manner for the collection for such Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Issuer, as the case may be, and
any other Person. 
 Section     .9. Securityholders Authorize Trustee to Effectuate Subordination
of Securities. Each Holder of Subordinated Securities by his acceptance thereof authorizes and expressly directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this
Article      and appoints the Trustee his attorney-in-fact for such purpose, including in the event of any dissolution, winding up, liquidation or reorganization of the Issuer (whether in bankruptcy, insolvency or
receivership proceedings or upon an assignment for the benefit of creditors or otherwise) the immediate filing of a claim for the unpaid balance of his Subordinated Securities in the form required in said proceedings and causing said claim to be
approved. If the Trustee does not file a proper claim or proof of debt in the form required in such proceeding prior to 30 days before the expiration of the 

  
 D-6









 
time to file such claim or claims, then the holders of Senior Indebtedness have the right to file and are hereby authorized to file an appropriate claim for and on behalf of the Holders of said
Subordinated Securities. 
 Section     .10. Right of Trustee to Hold Senior Indebtedness. The
Trustee in its individual capacity shall be entitled to all of the rights set forth in this Article      in respect of any Senior Indebtedness at any time held by it to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall be construed to deprive the Trustee of any of its rights as such holder. 

With respect to the holders of Senior Indebtedness of the Issuer, the Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this Article     , and no implied covenants or obligations with respect to the holders of such Senior Indebtedness shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and, subject to the provisions of Sections     .2 and     .3, the Trustee shall not
be liable to any holder of such Senior Indebtedness if it shall pay over or deliver to Holders of Subordinated Securities, the Issuer or any other Person money or assets to which any holder of such Senior Indebtedness shall be entitled by virtue of
this Article      or otherwise. 
 Section     .11. Article
     Not to Prevent Events of Defaults. The failure to make a payment on account of principal or interest by reason of any provision in this Article      shall not be construed as preventing the
occurrence of an Event of Default under Section     .

 SCHEDULE 1 
 PRICING SCHEDULE 
 The Applicable Margin shall be determined pursuant to the table
below. 
  

																					
	 	  	Pricing Level I	 	 	Pricing Level II	 	 	Pricing Level III	 	 	Pricing Level IV	 	 	Pricing Level V	 
	 Commitment Fee Rate
	  	 	0.10	% 	 	 	0.125	% 	 	 	0.175	% 	 	 	0.20	% 	 	 	0.25	% 
	 Applicable Margin for Eurodollar Rate Loans
	  	 	1.00	% 	 	 	1.125	% 	 	 	1.25	% 	 	 	1.50	% 	 	 	1.75	% 
	 Applicable Margin for Floating Rate Loans
	  	 	0.00	% 	 	 	0.125	% 	 	 	0.25	% 	 	 	0.50	% 	 	 	0.75	% 

 For purposes of the foregoing: 
 Changes in the Applicable Margin and the Commitment Fee Rate resulting from a change in the Pricing Level shall become effective on the effective date of any change in the Senior Debt Rating from S&P
or Moody’s. In the event of a split in the Senior Debt Rating from S&P and Moody’s that would otherwise result in the application of more than one Pricing Level (had the provisions regarding the applicability of other Pricing Levels
contained in the definitions thereof not been given effect), then the Applicable Margin and the Commitment Fee Rate shall be determined as follows: (x) if the split in the Senior Debt Rating is one Pricing Level, then the higher Senior Debt
Rating will be the applicable Pricing Level, (y) if the split in the Senior Debt Rating is two Pricing Levels, the midpoint between the two will be the applicable Pricing Level, and (z) if the split in the Senior Debt Rating is more than
two Pricing Levels, the Pricing Level will be the Pricing Level immediately below the higher Pricing Level. If either (but not both) Moody’s or S&P shall cease to be in the business of rating corporate debt obligations, the Pricing Levels
shall be determined on the basis of the Senior Debt Ratings provided by the other rating agency. If at any time both the Secured Debt and the Unsecured Debt of the Company is unrated by Moody’s and S&P, the Pricing Level will be Pricing
Level V; provided that if the reason that there is no such Senior Debt Rating results from Moody’s and S&P ceasing to issue debt ratings generally, then the Company and the Agent may select a Substitute Rating Agency for purposes of
the foregoing Pricing Schedule (and all references in the Credit Agreement to Moody’s and S&P, as applicable, shall refer to such Substitute Rating Agency), and until a Substitute Rating Agency is so selected, the Pricing Level shall be
determined by reference to the Senior Debt Rating most recently in effect prior to cessation. 
 “Pricing
Level” means Pricing Level I, Pricing Level II, Pricing Level III, Pricing Level IV or Pricing Level V, as the context may require. 

  
 Sch.-1









 “Pricing Level I” means any time when (i) no Event of Default has
occurred and is continuing and (ii) the Senior Debt Rating is A or higher by S&P or A2 or higher by Moody’s. 

“Pricing Level II” means any time when (i) no Event of Default has occurred and is continuing, (ii) the Senior
Debt Rating is A- or higher by S&P or A3 or higher by Moody’s and (iii) Pricing Level I does not apply. 

“Pricing Level III” means any time when (i) no Event of Default has occurred and is continuing, (ii) the
Senior Debt Rating is BBB+ or higher by S&P or Baa1 or higher by Moody’s and (iii) none of Pricing Level I or Pricing Level II is applicable. 
 “Pricing Level IV” means any time when (i) no Event of Default has occurred and is continuing, (ii) the Senior Debt Rating is BBB or higher by S&P or Baa2 or higher by
Moody’s and (iii) none of Pricing Level I, Pricing Level II or Pricing Level III is applicable. 
 “Pricing
Level V” means any time when none of Pricing Levels I, II, III or IV is applicable. 
 “Secured Debt”
means senior, secured, long-term indebtedness for borrowed money of the Company that is not guaranteed by any other Person or subject to any other credit enhancement, including, for the avoidance of doubt, the First Mortgage Bonds. 

“Senior Debt Rating” means at any date, the credit rating identified by S&P or Moody’s as the credit rating
which (i) it has assigned to Secured Debt of the Company or (ii) would assign to Secured Debt of the Company were the Company to issue or have outstanding any Secured Debt on such date; provided that if the Secured Debt of the
Company is unrated by both of Moody’s and S&P, “Senior Debt Rating” means the credit rating that is one level higher than the credit rating identified by S&P or Moody’s as the credit rating which (i) it has
assigned to Unsecured Debt of the Company or (ii) would assign to Unsecured Debt of the Company were the Company to issue any Unsecured Debt on such date. 
 “Substitute Rating Agency” means a nationally-recognized rating agency (other than Moody’s and S&P). 
 “Unsecured Debt” means senior, unsecured, long-term indebtedness for borrowed money of the Company that is not guaranteed by any other Person or subject to any other credit enhancement.
