(B) when the Borrower has Issuer Ratings from only two of S&P, Moody’s and Fitch: (i) if both of the two Issuer Ratings are in the same Pricing Level, such Pricing Level shall

apply and (ii) if the two Issuer Ratings are split-rated (x) by one Pricing Level, the Pricing Level shall be determined by the higher of the two (e.g., an Issuer Rating of BBB-/Baa2 results in Pricing Level III) or (y) by more than one Pricing Level, the Pricing Level shall be determined by the Pricing Level one below the Pricing Level which corresponds to the higher Issuer Rating (e.g., an Issuer Rating of BBB-/Baa1 results in Pricing Level III and an Issuer Rating of BBB+/Baa3 results in Pricing Level III);

(C) when the Borrower has an Issuer Rating from only one of S&P, Moody’s and Fitch: the Pricing Level shall be determined by reference to the Pricing Level immediately below the Pricing Level which corresponds to the one Issuer Rating in effect (provided that if the one Issuer Rating in effect corresponds to Pricing Level V, then Pricing Level V shall apply); and

Each change in the Applicable Margin shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of S&P, Moody’s or Fitch shall change, or if any such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Administrative Agent (in consultation with the Lenders) shall negotiate in good faith to amend this definition to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Margin shall be determined by reference to the rating most recently in effect prior to such change or cessation.

It is hereby understood and agreed that (a) the Commitment Fee shall be adjusted from time to time based upon the Sustainability Fee Adjustment (to be calculated and applied as set forth in Schedule 1.02) and (b) the Applicable Margin with respect to EurodollarTerm Benchmark Borrowings, RFR Borrowings, ABR Borrowings and Letters of Credit shall be adjusted from time to time based upon the Sustainability Margin Adjustment (to be calculated and applied as set forth in Schedule 1.02); provided that in no event shall any of the Commitment Rate, the EurodollarTerm Benchmark Margin, the RFR Margin or the ABR Margin be less than 0.00%.

“Applicable Percentage” means, with respect to any Lender, the percentage of the total Commitments represented by such Lender’s Commitments; provided that, in the case of Section 2.12 when a Defaulting Lender shall exist, “Applicable Percentage” shall mean the percentage of the total Commitments (disregarding any Defaulting Lender’s Commitments) represented by such Lender’s Commitments. If the Commitments have terminated or expired, the Applicable Percentages shall be determined based upon the Commitments most recently in effect, giving effect to any assignments and to any Lender’s status as a Defaulting Lender at the time of such determination.

“Approved Electronic Platform” has the meaning assigned to such term in Section 9.09(a).

“Approved Fund” means, with respect to any Lender, any Person (other than a natural person) that is (or will be) engaged in making, purchasing, holding or otherwise investing in bank loans and similar extensions of credit in the ordinary course of its business that is administered or managed by (a) such Lender or (b) an Affiliate of such Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

“Assignment and Acceptance” means an assignment and acceptance entered into by a Lender and an assignee (with the consent of each party whose consent is required by Section 10.04), and accepted by the Administrative Agent, substantially in the form of Exhibit A or any other form (including electronic records generated by the use of an electronic platform) approved by the Administrative Agent, including the forms described in the last sentence of Section 3.08(b) and Section 10.02(d) and executed by the parties described therein.

“Availability Period” means the period from and including the Effective Date to (but excluding) the Commitment Termination Date.

The interest rate on Eurodollar Loans is determined by reference to the LIBO Rate, which is derived from the London interbank offered rate (“LIBOR”).

On March 5, 2021, the U.K. Financial Conduct Authority (the “FCA”) publicly announced that: (a) immediately after December 31, 2021, publication of the 1-week and 2-month U.S. Dollar LIBOR settings will permanently cease; (b) immediately after June 30, 2023, publication of the overnight and 12-month U.S. Dollar LIBOR settings will permanently cease; and (c) immediately after June 30, 2023, the 1-month, 3-month and 6-month U.S. Dollar LIBOR settings will cease to be provided or, subject to the FCA’s consideration of the case, be provided on a changed methodology (or “synthetic”) basis and no longer be representative of the underlying market and economic reality they are intended to measure and that representativeness will not be restored. There is no assurance that dates announced by the FCA will not change or that the administrator of LIBOR and/or regulators will not take further action that could impact the availability, composition, or characteristics of LIBOR or the currencies and/or tenors for which LIBOR is published. Each party to this agreement should consult its own advisors to stay informed

of any such developments. Public and private sector industry initiatives are currently underway to identify new or alternative reference rates to be used in place of LIBORa Loan denominated in Dollars may be derived from an interest rate benchmark that may be discontinued or is, or may in the future become, the subject of regulatory reform. Upon the occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, Section 3.04(b) and Section 3.04(c) provide theprovides a mechanism for determining an alternative rate of interest. The Administrative Agent will promptly notify the Borrower, pursuant to Section 3.04(e), of any change to the reference rate upon which the interest rate on Eurodollar Loans is based. However, the Administrative Agent does not warrant or accept any responsibility for, and shall not have any liability with respect to, the administration, submission, performance or any other matter related to LIBOR or other rates in the definition of “LIBO Rate”any interest rate used in this Agreement, or with respect to any alternative or successor rate thereto, or replacement rate thereof (including, without limitation, (i) any such alternative, successor or replacement rate implemented pursuant to Section 3.04(b) or Section 3.04(c), whether upon the occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, and (ii) the implementation of any Benchmark Replacement Conforming Changes pursuant to Section 3.04(d)),, including without limitation, whether the composition or characteristics of any such alternative, successor or replacement reference rate will be similar to, or produce the same value or economic equivalence of, the LIBO Rateexisting interest rate being replaced or have the same volume or liquidity as did LIBORany existing interest rate prior to its discontinuance or unavailability. The Administrative Agent and its affiliates and/or other related entities may engage in transactions that affect the calculation of any interest rate used in this Agreement or any alternative, successor or alternative rate (including any Benchmark Replacement) and/or any relevant adjustments thereto, in each case, in a manner adverse to the Borrower.

Unless otherwise specified herein, the amount of a Letter of Credit at any time shall be deemed to be the amount of such Letter of Credit available to be drawn at such time; provided that, with respect to any Letter of Credit that, by its terms or the terms of any Letter of Credit Agreement related thereto, provides for one or more automatic increases in the available amount thereof, the amount of such Letter of Credit shall be deemed to be the maximum amount of such Letter of Credit after giving effect to all such increases, whether or not such maximum amount is available to be drawn at such time.

For all purposes under the Loan Documents, in connection with any division or plan of division under Delaware law (or any comparable event under a different jurisdiction’s laws): (a) if any asset, right, obligation or liability of any Person becomes the asset, right, obligation or liability of a different Person, then it shall be deemed to have been transferred from the original Person to the subsequent Person, and (b) if any new Person comes into existence, such new Person shall be deemed to have been organized and acquired on the first date of its existence by the holders of its Equity Interests at such time.

ARTICLE 2. THE CREDITS

Section 2.01 Commitments

Prior to the Effective Date, certain loans were previously made to the Borrower under the Existing Credit Agreement which remain outstanding as of the date of this Agreement (such outstanding loans being hereinafter referred to as the “Existing Loans”). Subject to the terms and conditions set forth in this Agreement, the Borrower and each of the Lenders agree that on the Effective Date but subject to the satisfaction of the conditions precedent set forth in Section 5.01 and the reallocation and other transactions described in Section 1.04, the Existing Loans shall, as of the Effective Date, be reevidenced as Revolving Loans under this Agreement and the terms of the Existing Loans shall be restated in their entirety and shall be evidenced by this Agreement. Subject to the terms and conditions set forth herein, each Lender agrees to make Revolving Loans to the Borrower from time to time during the Availability Period in an aggregate principal amount that will not result (after giving effect to any application of proceeds of such Borrowing to any Swingline Loans outstanding pursuant to Section 2.06(a)) in (a) such Lender’s Revolving Credit Exposure exceeding such Lender’s Revolving Commitment or (b) the sum of the total Revolving Credit Exposures exceeding the Aggregate Revolving Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Revolving Loans.

Section 2.02 Loans and Borrowings

(a)Each Revolving Loan shall be made as part of a Borrowing consisting of Revolving Loans made by the Lenders ratably in accordance with their respective Revolving Commitments. The failure of any Lender to make any Revolving Loan required to be made by it shall not relieve any other Lender of its obligations hereunder, provided that the Revolving Commitments of the Lenders are several, and no Lender shall be responsible for any other Lender’s failure to make Revolving Loans as required. Any Swingline Loan shall be made in accordance with the procedures set forth in Section 2.13.

(b)Subject to Section 3.04, each Revolving Loan shall be an ABR Loan or a EurodollarTerm Benchmark Loan, as the Borrower may request in accordance herewith (including Section 3.02). Each Swingline Loan shall be an ABR Loan. Each Lender at its option may make any EurodollarTerm Benchmark Loan (and any ABR Loan, the interest on which is determined pursuant to clause (c) of the definition of Alternate Base Rate) by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan (and in the case of an Affiliate, the provisions of Sections 3.05, 3.06 and 3.07 shall apply to such Affiliate to the same extent as to such Lender), provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement and neither such Lender nor such Affiliate shall be entitled to any amounts payable under Sections 3.05 or 3.07 solely in respect of increased costs or taxes resulting from such exercise and existing at the time of such exercise.

(c)At the commencement of each Interest Period for any EurodollarTerm Benchmark Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $1,000,000. At the time that each ABR Borrowing (other than a Swingline Loan) is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $1,000,000, provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Revolving Commitments. Each Swingline Loan shall be in an amount that is an integral multiple of $500,000 and not less than $1,000,000. Borrowings of more than one Type and Class may be

outstanding at the same time, provided that there shall not at any time be more than a total of fifteen EurodollarTerm Benchmark Borrowings outstanding.

(d)Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Eurodollar Borrowing if the Interest Period requested with respect thereto would end after the Commitment Termination Date.

Section 2.03 Requests for Borrowings

To request a Borrowing (other than a Swingline Loan, requests for which are governed by Section 2.13), the Borrower shall notify the Administrative Agent of such request either (x) by email from (with such email request being confirmed promptly by delivery of a written Borrowing Request signed by) the President of the Borrower, a Financial Officer or the Hawaiian Electric Cash Manager or (y) by delivery of a written Borrowing Request signed by the President of the Borrower, a Financial Officer or the Hawaiian Electric Cash Manager, (a) in the case of a EurodollarTerm Benchmark Borrowing, not later than 3:00 p.m., New York City time, three U.S. Government Securities Business Days before the date of the proposed Borrowing, or (b) in the case of an ABR Borrowing, not later than 2:00 p.m., New York City time on the date of the proposed Borrowing. Each such Borrowing Request shall be irrevocable (except as otherwise provided in Section 3.04). Each such Borrowing Request shall specify the following information in compliance with Section 2.02:

(i)the aggregate amount of the requested Borrowing;

(ii)the date of such Borrowing, which shall be a Business Day;

(iii)whether such Borrowing is to be an ABR Borrowing or a EurodollarTerm Benchmark Borrowing;

(iv)in the case of a EurodollarTerm Benchmark Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and

(v)the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.04.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested EurodollarTerm Benchmark Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Revolving Loan to be made as part of the requested Borrowing.

Section 2.04 Funding of Borrowings

(a)Each Lender shall make each Revolving Loan to be made by it hereunder on the proposed date thereof solely by wire transfer of immediately available funds by 3:00 p.m., New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. Swingline Loans shall be made as provided in Section 2.13. Subject to Section 5.02, the Administrative Agent will make the proceeds of such Loans available to the Borrower by promptly crediting or otherwise transferring the amounts so

received, in like funds, to an account of the Borrower designated by the Borrower in the applicable Borrowing Request.

(b)Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Revolving Loan that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent by 3:00 p.m., New York City time, for a EurodollarTerm Benchmark Borrowing or by 4:00 p.m., New York City time, for an ABR Borrowing on the applicable day, then such Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount was made available by the Administrative Agent to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Rate and a rate per annum determined by the Administrative Agent in accordance with banking industry rules on interbank compensation, or (ii) in the case of the Borrower, the interest rate that would be otherwise applicable to such Borrowing. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Revolving Loan included in such Borrowing. Such payment by the Borrower shall be without prejudice to its rights against each Lender who fails to fund its share of any Borrowing.

Section 2.05 Termination, Reduction and Increase of Commitments

(a)Unless previously terminated, the Revolving Commitments and the Letter of Credit Commitments shall terminate on the Commitment Termination Date; provided however, upon delivery to the Administrative Agent of a copy of an order or approval issued by the PUC, certified by a Financial Officer to be true and complete, which is final and not subject to review or appeal, that approves the extension of the date set forth in clause (a) of the definition of Commitment Termination Date, then the date set forth in clause (a) of the definition of Commitment Termination Date shall be automatically extended to the latest date permitted by such order or approval but in no event later than May 14, 2026..

(b)The Borrower may at any time terminate, or from time to time reduce, the Commitments, provided that (i) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.07 and/or any concurrent cash collateralization of the Letter of Credit Exposure, (w) the amount of any Lender’s Revolving Credit Exposure would exceed its Revolving Commitment, (x) the Aggregate Credit Exposure would exceed the Aggregate Revolving Commitments, (y) the total Revolving Credit Exposures of all of the Lenders would exceed the Aggregate Revolving Commitments or (z) the Aggregate Letter of Credit Exposure would exceed the Aggregate Letter of Credit Commitments, and (ii) each such reduction shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000.

(c)The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under paragraph (b) of this Section at least two Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided, that a notice of termination of the Commitments delivered by the

Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments hereunder shall be permanent but without prejudice to the rights of the Borrower under paragraph (d) below. Each reduction of the Commitments hereunder shall be made ratably among the Lenders in accordance with their respective Commitments.

(d)Provided that immediately before and after giving effect thereto, no Default shall or would exist and be continuing and the conditions set forth in Section 5.02 have been satisfied or waived, the Borrower may at any time and from time to time, on or before the Commitment Termination Date referred to in clause (a) of the definition thereof (including after giving effect to any extension thereof pursuant to Section 2.05(a)), request any one or more of the Lenders to increase (such decision to be within the sole and absolute discretion of such Lender) its Revolving Commitment and Letter of Credit Commitment, and/or any other Eligible Assignee reasonably satisfactory to the Administrative Agent and the Borrower, to provide a new Revolving Commitment and a new Letter of Credit Commitment, by submitting an Increase Request in the form of Exhibit F (an “Increase Request”), duly executed by the Borrower and each such Lender or Eligible Assignee, as the case may be. Thereupon, the Administrative Agent shall execute such Increase Request and deliver a copy thereof to the Borrower and each such Lender or Eligible Assignee, as the case may be.

Upon execution and delivery of such Increase Request, (i) in the case of each such Lender, such Lender’s Revolving Commitment shall be increased to the amount set forth in such Increase Request, (ii) in the case of each such Eligible Assignee, such Eligible Assignee shall become a party hereto and shall for all purposes of the Loan Documents be deemed a “Lender” with a Revolving Commitment in the amount set forth in such Increase Request, and (iii) the Borrower shall contemporaneously therewith execute and deliver to the Administrative Agent a Note or Notes for each such Eligible Assignee providing a new Revolving Commitment and for such existing Lender increasing its Revolving Commitment provided, however, that:

(i)immediately after giving effect thereto, the Aggregate Revolving Commitments shall not have been increased pursuant to this subsection (d) to an amount greater than the sum of (x) $275,000,000 plus (y) the amount of the Revolving Commitment of each Lender that becomes a Defaulting Lender;

(ii)each such increase shall be in an amount not less than $5,000,000 or such amount plus an integral multiple of $1,000,000;

(iii) the Revolving Commitments shall not be increased on more than three occasions;

(iv) the Administrative Agent shall have received documents (including, without limitation, one or more opinions of counsel) consistent with those delivered on the Effective Date as to the corporate power and authority of the Borrower to borrow hereunder after giving effect to such increase;

(v)if Loans shall be outstanding immediately after giving effect to such increase, the Lenders shall, upon the acceptance of the Increase Request by, and at the direction of, the Administrative Agent, make appropriate adjustments among themselves so that the amount of Revolving Credit Exposures from any of the Lenders under this

Agreement are allocated among the Lenders according to their Commitment Percentages after giving effect to the increase in the Aggregate Revolving Commitments

(it being understood and agreed that any reallocation made pursuant to this clause (v) shall require the Borrower to make payment pursuant to Section 3.06 with respect to any affected EurodollarTerm Benchmark Loans);

(vi) each such Eligible Assignee shall have delivered to the Administrative Agent and the Borrower an Administrative Questionnaire and all forms, if any, that are required to be delivered by such Eligible Assignee pursuant to Section 3.07(e); and

(vii)the Administrative Agent shall have received (1) a copy of an order or approval issued by the PUC, certified by a Financial Officer to be true and complete, which is final and not subject to review or appeal, that authorizes the Borrower to obtain any increase in the Commitments requested by the Borrower and (2) a certificate of a Financial Officer attaching thereto resolutions of the Board of Directors of the Borrower authorizing any increase of the Commitments requested by the Borrower.

Section 2.06 Repayment of Loans; Evidence of Debt

(a)The Borrower hereby unconditionally promises to pay (i) to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan on the Commitment Termination Date and (ii) to the Administrative Agent for the account of the Swingline Lender the then unpaid principal amount of each Swingline Loan on the earlier of the Commitment Termination Date and the date that is the 21st Business Day after such Swingline Loan is made; provided that on each date that a Revolving Loan is made, the Borrower shall repay all Swingline Loans then outstanding and the proceeds of any such Borrowing shall be applied by the Administrative Agent to repay any Swingline Loans outstanding.

(b)Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the Indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c)The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type and Class thereof and, if applicable, the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d)The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall, to the extent not inconsistent with any entries made in any Note, be prima facie evidence of the existence and amounts of the obligations recorded therein except for clearly demonstrated error; provided, that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement; provided, further, that in the event of any inconsistency between the accounts maintained by the Administrative Agent pursuant to paragraph (c) and any Lender’s records, the accounts of the Administrative Agent shall govern.

(e)The Loans of each Lender and interest thereon shall at all times (including after assignment pursuant to Section 10.04) be evidenced by one or more Notes payable to such Lender (or its registered assigns).

Section 2.07 Prepayment of Loans

(a)The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to the requirements of this Section.

(b)In the event of any partial reduction or termination of the Commitments, then (i) at or prior to the date of such reduction or termination, the Administrative Agent shall notify the Borrower and the Lenders of the Aggregate Credit Exposures after giving effect thereto, and (ii) if such sum would exceed the Aggregate Revolving Commitments after giving effect to such reduction or termination, then the Borrower shall, on the date of such reduction or termination, prepay Revolving Borrowings, and/or cash collateralize the Letter of Credit Exposure, in an amount sufficient to eliminate such excess.

(c)Mandatory Prepayments.

(i)The Borrower shall immediately prepay the Loans, by an amount equal to the excess, if any, of the aggregate outstanding principal balance of the Loans over the Aggregate Revolving Commitments.

(ii)Simultaneously with each reduction or termination of the Revolving Commitments, (1) in the event that the Aggregate Letter of Credit Commitments shall exceed the Aggregate Revolving Commitments as so reduced or terminated, the Aggregate Letter of Credit Commitments shall be automatically reduced, and/or the Letter of Credit Exposure shall be cash collateralized, by an amount equal to such excess, and (2) the Borrower shall prepay the Loans by an amount equal to the excess, if any, of the aggregate outstanding principal balance of the Loans over the Aggregate Revolving Commitments as so reduced or terminated.

(d)Simultaneously with each prepayment of a Loan, the Borrower shall, if and to the extent required by Section 3.01(de), prepay all accrued interest on the amount prepaid through the date of prepayment.

(e)The Borrower shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by either (x) email notice, which may be given by the President of the Borrower, a Financial Officer or the Hawaiian Electric Cash Manager of any prepayment under Section 2.07(a) (with such email notice being confirmed promptly by delivery of a written notice in a form approved by the Administrative Agent signed by the President of the Borrower, a Financial Officer or the Hawaiian Electric Cash Manager) or (y) written notice in a form approved by the Administrative Agent signed by the President of the Borrower, a Financial Officer or the Hawaiian Electric Cash Manager (i) in the case of prepayment of (x) a EurodollarTerm Benchmark Borrowing, not later than 2:00 p.m., New York City time, three Business Days before the date of prepayment or (y) an RFR Revolving Borrowing, not later than 11:00 a.m., New York City time, five (5) Business Days before the date of prepayment, (ii) in the case of prepayment of an ABR Borrowing (other than a Swingline Loan), not later than 2:00 p.m., New York City time, on the Business Day of the prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than 1:00 p.m., New York City time, on the Business Day of prepayment. Each such notice shall be irrevocable and shall specify the

prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided, that if a notice of prepayment is given in connection with a conditional notice of termination of the Commitments contemplated by Section 2.05(c), then such notice of prepayment may also be conditional and may be revoked if such notice of termination is revoked in accordance with Section 2.05(c). Promptly following receipt of any such notice relating to a prepayment of a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing under Section 2.07(a) shall, be in an integral multiple of $1,000,000 and not less than $1,000,000. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest if and to the extent required by Section 3.01.

Section 2.08 Payments Generally; Pro Rata Treatment; Sharing of Setoffs

(a)The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest or fees, or of amounts payable under Section 3.05, 3.06, 3.07 or 10.03, or otherwise) in Dollars prior to 3:00 p.m., New York City time, on the date when due, in immediately available funds, without setoff or counterclaim.

Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its office at 10 South Dearborn Street, Chicago, Illinois, 60603, or such other office as to which the Administrative Agent may notify the other parties hereto, except payments to be made directly to the Issuing Bank or the Swingline Lender as expressly provided herein and except that payments pursuant to Sections 3.03(b) (with respect to the fronting fee and other amounts payable to the Issuing Bank), 3.03(c), 3.05, 3.06, 3.07, 3.08, 10.03 and 10.04 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. In the event the Administrative Agent has not in fact made available to each Lender its share of the applicable payment within one Business Day of the receipt thereof, then the Administrative Agent agrees to pay to the applicable Lender forthwith on demand its share of such payment with interest thereon for each day, from and including the second Business Day after such payment was received by the Administrative Agent but excluding the date of payment by the Administrative Agent, at the greater of the Federal Funds Rate and a rate per annum determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment of accrued interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b)If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal of Loans, interest, fees and commissions then due hereunder, such funds shall be applied (i) first, towards payment of interest, fees and commissions then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest, fees and commissions then due to such parties, and (ii) second, towards payment of principal of Loans then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal of Loans then due to such parties.

(c)If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of, or interest on, any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender

receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of, and accrued interest on, their respective Loans, provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant. The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d)Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the applicable Credit Parties hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to such Credit Parties the amount due. In such event, if the Borrower has not in fact made such payment, then each such Credit Party severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Credit Party with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate per annum determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e)If any Credit Party shall fail to make any payment required to be made by it pursuant to Section 2.04(b), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Credit Party to satisfy such Credit Party’s obligations under such Section until all such unsatisfied obligations are fully paid.

Section 2.09 Letter of Credit Sub-Facility

(a)Subject to the terms and conditions of this Agreement, the Issuing Bank, in reliance on the agreement of the other Lenders set forth in Section 2.10, may agree, but shall have no obligation, to issue standby or documentary letters of credit (the “Letters of Credit”; each, individually, a “Letter of Credit”) during the Availability Period for the account of the Borrower, provided that immediately after the issuance of each Letter of Credit (i) the Letter of Credit Exposure of each Lender (whether or not the conditions for drawing under any Letter of Credit have or may be satisfied) would not exceed its Letter of Credit Commitment, (ii) the Aggregate Credit Exposure would not exceed the Aggregate Revolving Commitments and (iii) each Lender’s Revolving Credit Exposure would not exceed such Lender’s Commitment. Notwithstanding the foregoing, the letters of credit identified on Schedule 2.09 (the “Existing Letters of Credit”) shall be deemed to be “Letters of Credit” issued on the Effective Date for all purposes of the Loan Documents. Each Letter of Credit issued pursuant to this Section shall have an expiration date which shall be not later than the earlier of (i) three hundred sixty-four days after the date of issuance thereof and (ii) five Business Days before the Commitment Termination Date referred to in clause (a) of the definition thereof, including any extension thereof

contemplated by Section 2.05(a), provided that any Letter of Credit with a three hundred sixty-four day tenor may provide for the periodic and/or successive renewals or extensions thereof for additional periods expiring prior to the earlier to occur of (x) three hundred sixty-four days after the date of such renewal or extension and (y) date referred to in clause (ii) above. No Letter of Credit shall be issued if the Administrative Agent, or the Required Lenders by notice to the Administrative Agent no later than 1:00 p.m. New York City time one Business Day prior to the requested date of issuance of such Letter of Credit, shall have determined that any condition set forth in Section 5.01 or 5.02 has not been satisfied. The Issuing Bank shall not be under any obligation to issue any Letter of Credit if: (i) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the Issuing Bank from issuing such Letter of Credit, or any law applicable to the Issuing Bank shall prohibit, or require that the Issuing Bank refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon the Issuing Bank with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Bank is not otherwise compensated hereunder) not in effect on the Effective Date, or shall impose upon the Issuing Bank any unreimbursed loss, cost or expense that was not applicable on the Effective Date and that the Issuing Bank in good faith deems material to it; or (ii) the issuance of such Letter of Credit would violate one or more policies of the Issuing Bank applicable to letters of credit generally.

(b)Each Letter of Credit shall be issued for the account of the Borrower in support of an obligation of the Borrower or a Subsidiary in favor of a beneficiary who has requested the issuance of such Letter of Credit as a condition to a transaction entered into in connection with the Borrower’s or such Subsidiary’s ordinary course of business. The Borrower shall give the Administrative Agent a Letter of Credit Request for the issuance of each Letter of Credit by 2:00 p.m. New York City time, two (2) Business Days prior to the requested date of issuance. If requested by the Issuing Bank, each Letter of Credit Request shall be accompanied by the Issuing Bank’s standard application and agreement for standby or documentary letters of credit, as applicable (each, a “Reimbursement Agreement”) executed by the President of the Borrower or a Financial Officer, and shall specify (i) the beneficiary of such Letter of Credit and the obligations of the Borrower or such Subsidiary in respect of which such Letter of Credit is to be issued, (ii) the Borrower’s proposal as to the conditions under which a drawing may be made under such Letter of Credit and the documentation to be required in respect thereof, (iii) the maximum amount to be available under such Letter of Credit, and (iv) the requested dates of issuance and expiration. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any Reimbursement Agreement, the terms and conditions of this Agreement shall control. Upon receipt of such Letter of Credit Request from the Borrower, the Administrative Agent shall promptly notify the Issuing Bank and each other Lender thereof. Each Letter of Credit shall be in form and substance reasonably satisfactory to the Issuing Bank, with such provisions with respect to the conditions under which a drawing may be made thereunder and the documentation required in respect of such drawing as the Issuing Bank shall reasonably require. Each Letter of Credit shall be used solely for the purposes described therein. The Issuing Bank shall, on the proposed date of issuance and subject to the terms and conditions of the Reimbursement Agreement, if any, and to the other terms and conditions of this Agreement, issue the requested Letter of Credit.

(c)Each payment by the Issuing Bank of a draft drawn under a Letter of Credit shall give rise to an obligation on the part of the Borrower to reimburse the Issuing Bank by 3:00 p.m. New York City time two Business Days after the date of such payment together with interest on the amount of such payment from the date such payment was made by the Issuing Bank; provided that, if the amount of the draft drawn under such Letter of Credit is not less than $1,000,000, the

(d)Additional Commitment Lenders. The Borrower shall have the right, but shall not be obligated, on or before the applicable Commitment Termination Date for any Non-Extending Lender to replace such Non-Extending Lender with, and add as “Lenders” under this Agreement in place thereof, one or more financial institutions that each qualify as an Eligible Assignee (each, an “Additional Commitment Lender”) approved by the Administrative Agent in accordance with the procedures provided in Section 3.08(b), each of which Additional Commitment Lenders shall have entered into an Assignment and Acceptance (in accordance with and subject to the restrictions contained in Section 10.04, with the Borrower or replacement Lender obligated to pay any applicable processing or recordation fee) with such Non-Extending Lender, pursuant to which such Additional Commitment Lenders shall, effective on or before the applicable Commitment Termination Date for such Non-Extending Lender, assume a Commitment (and, if any such Additional Commitment Lender is already a Lender, its Commitment shall be in addition to such Lender’s Commitment hereunder on such date).

The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications.

Section 10.02 Waivers; Amendments

(a) No failure or delay by any Credit Party in exercising any right or power under any Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Credit Parties under the Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be

construed as a waiver of any Default, regardless of whether any Credit Party may have had notice or knowledge of such Default at the time.

(b) Except as provided in Section 3.04(b), and Section 3.04(c) and Section 3.04(d), neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders, provided that no such agreement shall:

(i) increase the Commitment of any Lender without the written consent of such Lender,

(ii) reduce the principal amount of any Loan or Reimbursement Obligations, or reduce the rate of interest thereon (other than (x) the imposition of additional interest under Section 3.01(cd) and (y) for the avoidance of doubt pursuant to the provisions of the penultimate paragraph of Schedule 1.02), or reduce any fees or other amounts payable under the Loan Documents, without the written consent of each Lender directly affected thereby,

(iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees or other amounts payable under the Loan Documents, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Credit Party directly affected thereby,

(iv) change any provision hereof in a manner that would alter the ratable reduction of Revolving Commitments or the pro rata sharing of payments required by any Loan Document, without the written consent of each Credit Party,

(v) change the payment waterfall provisions of Section 2.12(b) without the written consent of each Credit Party, or

(vi) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender,

and provided, further, that no such agreement shall amend, modify or otherwise affect the rights or duties of (A) the Administrative Agent hereunder without the prior written consent of the Administrative Agent, (B) the Issuing Bank hereunder without the prior written consent of the Issuing Bank and (C) the Swingline Lender hereunder without the prior written consent of the Swingline Lender (it being understood that any change to Section 2.12 shall require the consent of the Administrative Agent, the Issuing Bank and the Swingline Lender); and provided further that no such agreement shall amend or modify the provisions of Section 2.09, Section 2.10 or Section 2.11 without the prior written consent of the Administrative Agent and the Issuing Bank. Notwithstanding the foregoing, no consent with respect to any amendment, waiver or other modification of this Agreement shall be required of any Defaulting Lender, except with respect to any amendment, waiver or other modification referred to in clause (i), (ii) or (iii) of the first proviso of this paragraph and then only in the event such Defaulting Lender shall be directly affected by such amendment, waiver or other modification.
