amount of the Aggregate Available Commitment) or an integral multiple of $1,000,000 in excess thereof and shall consist of Advances of the same Type made on the same day by the Lenders ratably according to their respective Percentages. Within the
limits of each Lender’s Commitment and as hereinabove and hereinafter provided, the Borrower may request Borrowings hereunder, and repay or prepay Revolving Advances pursuant to Section 2.12 and utilize the resulting increase
in the Aggregate Available Commitment for further Extensions of Credit in accordance with the terms hereof. 
 (b) The Swingline Lender
agrees, on the terms and conditions hereinafter set forth, to make advances (each, a “Swingline Advance,” and collectively, the “Swingline Advances”) to the Borrower, during the period from and
including the date hereof, to and up to, but excluding, the Swingline Termination Date (or, if earlier, the Termination Date), in an aggregate principal amount at any time outstanding not exceeding the Swingline Commitment. Swingline Advances may be
made even if the aggregate principal amount of Swingline Advances outstanding at any time, when added to the aggregate principal amount of the Revolving Advances made by the Swingline Lender in its capacity as a Lender outstanding at such time and
its LC Outstandings at such time, would exceed the Swingline Lender’s own Commitment at such time, but provided that no Borrowing of Swingline Advances shall be made if, immediately after giving effect thereto, the Outstanding Credits
would exceed the Aggregate Commitment at such time. Subject to and on the terms and conditions of this Agreement, the Borrower may borrow, repay (including by means of a Borrowing of Revolving Advances pursuant to Section 2.2(d))
and reborrow Swingline Advances. 
 (c) Subject to and upon the terms and conditions set forth herein, the Borrower may, by notice to the
Agent, which shall promptly notify the Lenders, not less than fifteen (15) Business Days prior to the Termination Date, convert all Revolving Advances outstanding as of the close of business on the Termination Date into Term Loans (the
“Term-Out Option”), provided that no Unmatured Default or Event of Default has occurred and is continuing, both immediately before and after giving effect to the conversion of such Revolving Advances. The Term Loans of
each Lender (i) shall, unless otherwise specifically provided herein, consist of Term Loans of the same Type, and (ii) shall not exceed in initial principal amount for such Lender an amount which equals the total principal amount of
Revolving Advances owed to such Lender and outstanding as of the close of business on the Termination Date. Once repaid, Term Loans may not be reborrowed.

 Section 2.2    Making the Advances. 
 (a) The Revolving Advances and the Term Loans (each, together with the Swingline Advances, a “Class” of Loan) shall, at the option
of the Borrower and subject to the terms and conditions of this Agreement, be either a Base Rate Advance or Eurodollar Rate Advance (each, a “Type” of Advance). The Swingline Advances shall be made and maintained as LIBOR
Market Index Rate Advances at all times. 
 (b) In order to make a Borrowing (other than (w) Borrowings of Swingline Advances, which
shall be made pursuant to Section 2.2(c), (x) Borrowings for the purpose of repaying Refunded Swingline Advances, which shall be made pursuant to Section 2.2(d), (y) Borrowings involving conversions of
Revolving Advances upon exercise of the Term-Out Option, which shall be made pursuant to Section 2.1(c) or (z) conversions of outstanding Advances made pursuant to Section 2.11), the Borrower will give the
Agent written notice not later than 11:00 a.m. (i) on the third Business Day prior to the date of the proposed Borrowing, in the case of a Borrowing comprised of Eurodollar Rate Advances and (ii) not later than 10:00 a.m. on the date of
the proposed Borrowing, in the case of a Borrowing comprised of Base Rate Advances. Each such notice of a Borrowing (a “Notice of Borrowing”) shall be by telecopier, telex or email (in accordance with procedures prescribed by
the Agent), in substantially the form of Exhibit 2.2(b) hereto, specifying therein the requested (A) date of such Borrowing, (B) Type of Advances comprising such Borrowing, (C) aggregate amount of such Borrowing and
(D) in the case of a Borrowing comprised of Eurodollar Rate Advances, the initial Interest Period for each such Advance. Each Lender shall, before (x) 12:00 noon on the date of such Borrowing, in the case of a Borrowing comprised of
Eurodollar Rate Advances, and (y) 1:00 p.m. on the date of such Borrowing, in the case of a Borrowing comprised of Base Rate Advances, make available for the account of its Applicable Lending Office to the Agent at its address referred to in
Section 8.2, in same day funds, such Lender’s ratable portion of such Borrowing. After the Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent
will promptly make such funds available to the Borrower by means of a credit or wire transfer to the account specified in writing by the Borrower. 
 (c) In order to make a Borrowing of a Swingline Advance, the Borrower will give the Agent (and the Swingline Lender, if the Swingline Lender is not also the Agent) written notice not later than 2:00 p.m. on the date of such Borrowing. Each
such notice of a Borrowing (a “Notice of Swingline Borrowing”) shall be by telecopier, telex or email (in accordance with procedures prescribed by the Agent), in substantially the form of Exhibit 2.2(c) hereto,
specifying therein the requested (A) date of such Borrowing, and (B) aggregate amount of such Swingline Advance to be made pursuant to such Borrowing (which shall not be less than $1,000,000 and, if greater, shall be in an integral
multiple of $500,000 in excess thereof (or, if less, in the amount of the Unutilized Swingline Commitment)). Not later than 4:00 p.m. on the date of such Borrowing, the Swingline Lender will make available for the account of its Applicable Lending
Office to the Agent at its address referred to in Section 8.2, in same day funds, an amount equal to the amount of the requested Swingline Advance. After the Agent’s receipt of such funds and upon fulfillment of the
applicable conditions set forth in Article III, the Agent will promptly make such funds available to the Borrower by means of a credit or wire transfer to the account specified in writing by the Borrower. 
  

 20 

 (d) With respect to any outstanding Swingline Advances, the Swingline Lender may at any time (whether or
not an Event of Default has occurred and is continuing) in its sole and absolute discretion, and is hereby authorized and empowered by the Borrower to, cause a Revolving Advance to be made for the purpose of repaying such Swingline Advances by
delivering to the Agent (if the Agent is not also the Swingline Lender) and each other Lender (on behalf of, and with a copy to, the Borrower), not later than 11:00 a.m. one (1) Business Day prior to the proposed date of such Borrowing
therefor, a notice (which shall be deemed to be a Notice of Borrowing given by the Borrower) requesting the Lenders to make Revolving Advances (which shall be made initially as Base Rate Advances) on such date of Borrowing in an aggregate amount
equal to the amount of such Swingline Advances (the “Refunded Swingline Advances”) outstanding on the date such notice is given that the Swingline Lender requests to be repaid. Not later than 1:00 p.m. on the requested date
of such Borrowing, each Lender (other than the Swingline Lender) will make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.2, in same day funds, such Lender’s
ratable portion of such Borrowing. To the extent the Lenders have made such amounts available to the Agent as provided hereinabove, the Agent will make the aggregate of such amounts available to the Swingline Lender in like funds as received by the
Agent, which shall apply such amounts in repayment of the Refunded Swingline Advances. Notwithstanding any provision of this Agreement to the contrary, on the relevant date of such Borrowing, the Refunded Swingline Advances (including the Swingline
Lender’s ratable share thereof, in its capacity as a Lender) shall be deemed to be repaid with the proceeds of the Revolving Advances made as provided above (including a Revolving Advance deemed to have been made by the Swingline Lender), and
such Refunded Swingline Advances deemed to be so repaid shall no longer be outstanding as Swingline Advances but shall be outstanding as Revolving Advances. If any portion of any such amount repaid (or deemed to be repaid) to the Swingline Lender
shall be recovered by or on behalf of the Borrower from the Swingline Lender in any bankruptcy, insolvency or similar proceeding or otherwise, the loss of the amount so recovered shall be shared ratably among all the Lenders in the manner
contemplated by Section 2.18. 
 (e) If, as a result of any bankruptcy, insolvency or similar proceeding with respect to
the Borrower, Revolving Advances are not made pursuant to Section 2.2(d) in an amount sufficient to repay any amounts owed to the Swingline Lender in respect of any outstanding Swingline Advances, or if the Swingline Lender is
otherwise precluded for any reason from giving a notice on behalf of the Borrower as provided for hereinabove, the Swingline Lender shall be deemed to have sold without recourse, representation or warranty (except for the absence of Liens thereon
created, incurred or suffered to exist by, through or under the Swingline Lender), and each Lender shall be deemed to have purchased and hereby agrees to purchase, a participation in such outstanding Swingline Advances in an amount equal to its
ratable share (based on the proportion that its Commitment bears to the Aggregate Commitment at such time) of the unpaid amount thereof together with accrued interest thereon. Upon one (1) Business Day’s prior notice from the Swingline
Lender, each Lender (other than the Swingline Lender) will make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 8.2, in same day funds, such Lender’s respective
participation. To the extent the Lenders have made such amounts available to the Agent as provided hereinabove, the 

  

 21 

 
Agent will make the aggregate of such amounts available to the Swingline Lender in like funds as received by the Agent. In the event any such Lender fails to
make available to the Agent the amount of such Lender’s participation as provided in this Section 2.2(e), the Swingline Lender shall be entitled to recover such amount on demand from such Lender, together with interest
thereon for each day from the date such amount is required to be made available for the account of the Swingline Lender until the date such amount is made available to the Swingline Lender at the Federal Funds Rate for the first three
(3) Business Days and thereafter at the Applicable Rate for such Revolving Advances. Promptly following its receipt of any payment by or on behalf of the Borrower in respect of a Swingline Advance, the Swingline Lender will pay to each Lender
that has acquired a participation therein such Lender’s ratable share of such payment. 
 (f) Notwithstanding any provision of this
Agreement to the contrary, the obligation of each Lender (other than the Swingline Lender) to make Revolving Advances for the purpose of repaying any Refunded Swingline Advances pursuant to Section 2.2(d) and each such
Lender’s obligation to purchase a participation in any unpaid Swingline Advances pursuant to Section 2.2(e) shall be absolute and unconditional and shall not be affected by any circumstance or event whatsoever, including,
without limitation, (i) any set-off, counterclaim, recoupment, defense or other right that such Lender may have against the Swingline Lender, the Agent, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or
continuance of any Unmatured Default or Event of Default, (iii) the failure of the amount of such Borrowing of Revolving Advances to meet the minimum Borrowing amount specified in Section 2.1(a), or (iv) the failure of
any conditions set forth in Section 3.2 or elsewhere herein to be satisfied. 
 (g) All Term Loans made pursuant to
Section 2.1(c) shall be made by each Lender on the basis of such Lender’s Percentage as in effect immediately prior to the Termination Date. 
 (h) Each Notice of Borrowing and Notice of Swingline Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing which the related Notice of Borrowing specifies is to be comprised of
Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the
applicable conditions set forth in Article III, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Eurodollar
Rate Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date. 
 Section 2.3    Funding Reliance. 
 (a) Unless the Agent shall have received notice from a
Lender prior to the time of any Borrowing that such Lender will not make available to the Agent such Lender’s Advance as part of such Borrowing, the Agent may assume that such Lender has made such Advance available to the Agent on the time of
such Borrowing in accordance with Section 2.2 and the Agent may, in reliance upon such assumption, make available to the Borrower on such time a corresponding amount. If and to the extent that such Lender shall not have so made
such Advance available to the Agent, such Lender and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the time 

  

 22 

 
such amount is made available to the Borrower until the time such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate
applicable at the time to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such
Lender’s Advance as part of such Borrowing for purposes of this Agreement. 
 (b) The failure of any Lender to make the Advance to be
made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance
to be made by such other Lender on the date of any Borrowing. 
 Section 2.4    Letters of Credit.

 (a) Subject to the terms and conditions hereof, each Letter of Credit shall be issued (or the stated maturity thereof extended or terms
thereof modified or amended) on not less than two Business Days’ prior notice thereof by delivery of a Request for Issuance to the Agent and the LC Issuing Bank substantially in the form attached hereto in Exhibit 2.4. Each
Request for Issuance shall specify a statement of drawing conditions applicable to such Letter of Credit, and if such Request for Issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by the consent of the
beneficiary of the Letter of Credit thereto. The expiry of such Letter of Credit shall be no later than the earlier of (i) five Business Days’ prior to the Maturity Date and (ii) one (1) year after its date of issuance;
provided, however, that a Letter of Credit may, if requested by the Borrower, provide by its terms, and on terms acceptable to the LC Issuing Bank, for renewal for successive periods of one year or less (but not beyond the date five
Business Days prior to the applicable Maturity Date), unless and until the LC Issuing Bank shall have delivered a notice of nonrenewal to the beneficiary of such Letter of Credit. Each Request for Issuance shall be irrevocable unless modified or
rescinded by the Borrower not less than one day prior to the proposed date of issuance (or effectiveness) specified therein. Not later than 12:00 noon on the proposed date of issuance (or effectiveness) specified in such Request for Issuance, and
upon fulfillment of the applicable conditions precedent and the other requirements set forth herein, the LC Issuing Bank shall issue (or extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the Agent, which shall
promptly furnish copies thereof to the Lenders. 
 (b) No Letter of Credit shall be requested or issued hereunder if, after the issuance
thereof, the Outstanding Credits would exceed the total Commitments. 
 (c) The Borrower hereby agrees to pay to the Agent for the account of
the LC Issuing Bank and, if they shall have purchased participations in the reimbursement obligations of the Borrower pursuant to Section 2.4(d), the Lenders, on demand made by the LC Issuing Bank to the Borrower, on and after
each date on which the LC Issuing Bank shall pay any amount under any Letter of Credit issued by the LC Issuing Bank, a sum equal to the amount so paid plus interest on such amount from the date so paid by the LC Issuing Bank until repayment to the
LC Issuing Bank in full at a fluctuating interest rate per annum equal to the interest rate applicable to Base Rate Advances plus, if any amount paid by the LC Issuing Bank under a Letter of Credit is not reimbursed by the Borrower within three
Business Days, 2%. 
  

 23 

 (d) Immediately upon the issuance of any Letter of Credit, the LC Issuing Bank shall be deemed to have
sold and transferred to each Lender, and each Lender shall be deemed irrevocably and unconditionally to have purchased and received from the LC Issuing Bank, without recourse or warranty, an undivided interest and participation, pro rata (based on
such Lender’s Percentage), in such Letter of Credit, each drawing made thereunder and the obligations of the Borrower under this Agreement with respect thereto (other than the fees payable by the Borrower to the LC Issuing Bank). If the LC
Issuing Bank shall not have been reimbursed in full for any payment made by the LC Issuing Bank under a Letter of Credit issued by the LC Issuing Bank on the date of such payment, the LC Issuing Bank shall give the Agent and each Lender prompt
notice thereof (an “LC Payment Notice”) no later than 12:00 noon on the Business Day immediately succeeding the date of such payment by the LC Issuing Bank. Each Lender severally agrees, absolutely and unconditionally, to pay
to the Agent for the account of the LC Issuing Bank an amount equal to such Lender’s Percentage of such unreimbursed amount paid by the LC Issuing Bank, plus interest on such amount at a rate per annum equal to the Federal Funds Rate from the
date of the payment by the LC Issuing Bank to the date of payment to the LC Issuing Bank by such Lender. Each such payment by a Lender shall be made not later than 3:00 p.m. on the later to occur of (i) the Business Day immediately following
the date of such payment by the LC Issuing Bank and (ii) the Business Day on which such Lender shall have received an LC Payment Notice from the LC Issuing Bank. Each Lender’s obligation to make each such payment to the Agent for the
account of the LC Issuing Bank shall be several and shall not be affected by the occurrence or continuance of an Unmatured Default or Event of Default or the failure of any other Lender to make any payment under this Section 2.4(d)
or the failure of the LC Issuing Bank to provide the LC Payment Notice by 12:00 noon on the Business Day immediately succeeding the date of payment under a Letter of Credit by the LC Issuing Bank. Upon any change in the Commitment of any
Lender, with respect to all outstanding Letters of Credit and reimbursement obligations there shall be an automatic adjustment to the participations pursuant to this Section 2.4(d) to reflect the new pro rata shares of the
Lenders. 
 (e) The failure of any Lender to make any payment to the Agent for the account of the LC Issuing Bank in accordance with
Section 2.4(d) shall not relieve any other Lender of its obligation to make payment, but no Lender shall be responsible for the failure of any other Lender. If any Lender (a “Non-Performing Lender”) shall
fail to make any payment to the Agent for the account of the LC Issuing Bank in accordance with Section 2.4(d) within five Business Days after the LC Payment Notice relating thereto, then, for so long as such failure shall
continue, the LC Issuing Bank shall be deemed, for purposes of Section 8.1 and Article VI hereof, to be a Lender owed a Borrowing in an amount equal to the outstanding principal amount due and payable by such
Non-Performing Lender to the Agent for the account of the LC Issuing Bank pursuant to Section 2.4(d). Any Non-Performing Lender and the Borrower (without waiving any claim against such Lender for such Lender’s failure to
purchase a participation in the reimbursement obligations of the Borrower under Section 2.4(d)) severally agree to pay to the Agent for the account of the LC Issuing Bank forthwith on demand such amount, together with interest
thereon for each day from the date such Lender would have purchased its participation had it complied with the requirements of Section 2.4(d) until the date such amount is paid to the Agent at (i) in the case of the Borrower,
the interest rate applicable at the time to Base Rate Advances and (ii) in the case of such Lender, the rate applicable to Base Rate Advances plus 1%. 
  

 24 

 (f) The payment obligations of each Lender under Section 2.4(d) and of the Borrower
under this Agreement in respect of any payment under any Letter of Credit by the LC Issuing Bank shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including,
without limitation, the following circumstances: 
 (i) any lack of validity or enforceability of this Agreement, any other
Loan Document or any other agreement or instrument relating thereto or to such Letter of Credit; 
 (ii) any amendment or
waiver of, or any consent to departure from, the terms of this Agreement, any other Loan Document or such Letter of Credit; 
 (iii) the existence of any claim, set-off, defense or other right which the Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any Persons for whom any such beneficiary or any such
transferee may be acting), the LC Issuing Bank, the Agent, any Lender or any other Person, whether in connection with this Agreement, the transactions contemplated hereby, thereby or by such Letter of Credit, or any unrelated transaction;

 (iv) any statement or any other document presented under such Letter of Credit reasonably proving to be forged, fraudulent,
invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; 
 (v) payment in
good faith by the LC Issuing Bank under the Letter of Credit issued by the LC Issuing Bank against presentation of a draft or certificate that does not comply with the terms of such Letter of Credit; or 
 (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. 
 (g) The Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit. Neither the LC Issuing Bank, the
Lenders nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or responsible for (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof
in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) payment
by the LC Issuing Bank against presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit; or (iv) any other
circumstances whatsoever in making or failing to make payment under such Letter of Credit. Notwithstanding any provision to the contrary contained in any Loan Document, the Borrower and each Lender shall have the right to bring suit against the LC
Issuing Bank, and the LC Issuing Bank shall be liable to the Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender which the Borrower or such Lender proves were caused by
the LC Issuing Bank’s willful misconduct or gross negligence, including, in the case of the Borrower, the LC Issuing Bank’s 

  

 25 

 
willful failure to make timely payment under such Letter of Credit following the presentation to it by the beneficiary thereof of a draft and accompanying
certificate(s) that strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the LC Issuing Bank may accept sight drafts and accompanying certificates presented under the Letter
of Credit issued by the LC Issuing Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and payment against such documents shall not constitute
willful misconduct or gross negligence by the LC Issuing Bank. Notwithstanding the foregoing, no Lender shall be obligated to indemnify the Borrower for damages caused by the LC Issuing Bank’s willful misconduct or gross negligence. 

(h) If any Letter of Credit contains a provision pursuant to which it is deemed to be automatically renewed unless notice of termination of such
Letter of Credit is given by the LC Issuing Bank, the LC Issuing Bank shall timely give notice of termination if (i) as of close of business on the seventeenth day prior to the last day upon which the LC Issuing Bank’s notice of
termination may be given to the beneficiaries of such Letter of Credit, the LC Issuing Bank has received a notice of termination from the Borrower or a notice from the Agent that the conditions to issuance of such Letter of Credit have not been
satisfied, (ii) the renewed Letter of Credit would have a term not permitted by Section 2.4(a) or (iii) such Letter of Credit is the Existing Letter of Credit. 
 (i) If (i) as of the Termination Date, any Letter of Credit may for any reason remain outstanding, or (ii) at any time, the aggregate
Outstanding Credits shall exceed the Aggregate Commitment (after giving effect to any concurrent termination or reduction thereof), the Borrower shall (A) deliver to the Agent as cash collateral an amount in cash equal to the aggregate LC
Outstandings (whether or not any beneficiary under any Letter of Credit shall have drawn or be entitled at such time to draw thereunder) or, in the case of clause (ii) above, an amount in cash equal to such excess or (B) shall make some
other arrangements to provide credit support for such Letters of Credit reasonably satisfactory to the Agent. The Agent shall deposit such cash in a special collateral account of the Borrower pursuant to arrangements satisfactory to the Agent (such
account, the “Cash Collateral Account”) for the benefit of the Agent, the LC Issuing Bank and the Lenders. Such Cash Collateral Account shall at all times be free and clear of all rights or claims of third parties. The Cash
Collateral Account shall be maintained with the Agent in the name of, and under the sole dominion and control of, the Agent, and amounts deposited in the Cash Collateral Account shall bear interest at a rate equal to the rate generally offered by
Wachovia for deposits equal to the amount deposited by the Borrower in the Cash Collateral Account, for a term to be determined by the Agent, in its sole discretion. The Borrower hereby grants to the Agent for the benefit of the LC Issuing Bank and
the Lenders a Lien in and hereby assigns to the Agent for the benefit of LC Issuing Bank and the Lenders all of its right, title and interest in, the Cash Collateral Account and all funds from time to time on deposit therein to secure its
reimbursement obligations in respect of Letters of Credit. If any drawings then outstanding or thereafter made are not reimbursed in full immediately upon demand or, in the case of subsequent drawings, upon being made, then, in any such event, the
Agent may apply the amounts then on deposit in the Cash Collateral Account, toward the payment in full of any of the obligations as and when such obligations shall become due and payable. Any amounts remaining in the Cash Collateral Account
(including interest) after the expiration of all Letters of Credit and reimbursement in full of the LC Issuing Bank for all of its 

  

 26 

 
obligations thereunder shall be held by the Agent, for the benefit of the Borrower, to be applied against the Outstanding Credits, together with expenses
related thereto and accrued interest thereon, in such order and manner as the Agent may direct. If the Borrower is required to provide cash collateral in the case of clause (ii) above, such amount (including interest), to the extent not applied
as aforesaid, shall be returned to the Borrower on demand, provided that after giving effect to such return (i) the aggregate Outstanding Credits would not exceed the Aggregate Commitment at such time and (ii) no Unmatured Default
or Event of Default shall have occurred and be continuing at such time. 
 Section 2.5    Fees.

 (a) The Borrower agrees to pay to the Agent for the account of each Lender the Facility Fee, from the date hereof, in the case of
each Bank, and from the effective date specified in the Lender Assignment pursuant to which it became a Lender, in the case of each other Lender, until the later of the Maturity Date and the date all Advances are paid in full, payable quarterly in
arrears on the last day of each March, June, September and December during the term of such Lender’s Commitment, commencing December 31, 2006, and on the later of the Maturity Date and the date all Advances are paid in full. 
 (b) The Borrower shall pay to the Agent for the account of each Lender a fee (the “LC Fee”) on the average daily amount of the
sum of the undrawn stated amounts of all Letters of Credit outstanding on each such day, from the date hereof until the later to occur of the Maturity Date and the date on which no Letters of Credit are outstanding, payable on the last day of each
March, June, September and December (commencing December 31, 2006) and such later date, at a rate equal at all times to the Applicable Margin in effect from time to time for Eurodollar Rate Advances. In addition, the Borrower shall pay to the
LC Issuing Bank such fees for the issuance and maintenance of Letters of Credit and for drawings thereunder as may be separately agreed between the Borrower and the LC Issuing Bank. 
 (c) In addition to the fees provided for in Section 2.5(a) and Section 2.5(b), the Borrower shall pay (i) to
the Agent and the LC Issuing Bank, for their own accounts, such fees as are provided for in the Wachovia Fee Letter and (ii) to the Joint Lead Arrangers, for their own accounts, such fees as are provided for in the Wachovia Fee Letter and
Barclays Fee Letter. 
 Section 2.6    Changes in the Commitments. 
 (a) The Borrower shall have the right, upon at least three Business Days’ notice to the Agent, to terminate in whole or reduce ratably in part the
unused portions of the Aggregate Commitment; provided that the Aggregate Commitment shall not be reduced to an amount which is less than the aggregate principal amount of the Outstanding Credits; and provided, further, that each
partial reduction shall be in a minimum amount of $10,000,000 or any whole multiple of $1,000,000 in excess thereof. 
 (b) On the
Termination Date, the Aggregate Commitment shall be automatically reduced to zero. 
 (c) Any termination or reduction of the Aggregate
Commitment under this Section 2.6 shall be irrevocable, and the Aggregate Commitment shall not thereafter be reinstated. 
  

 27 

 (d) On any date prior to the Termination Date, the Borrower may on one or more occasions increase the
Aggregate Commitment by an amount not less than $5,000,000; provided that after giving effect to any such increase, the Aggregate Commitment shall not exceed $200,000,000 (any such increase, a “Commitment Increase”) by
designating either one or more of the existing Lenders (each of which, in its sole discretion, may determine whether and to what degree it may participate in such Commitment Increase) or one or more other Eligible Assignees reasonably acceptable to
the Agent that at the time agree, in the case of any such existing Lender, to increase its Commitment (an “Increasing Lender”) and, in the case of any such Eligible Assignee (an “Additional Lender”),
to become a party to this Agreement. 
 (i) The sum of the increases in the Commitments of the Increasing Lenders pursuant to
this Section 2.6(d) plus the Commitments of the Additional Lenders upon giving effect to the Commitment Increase shall not in the aggregate exceed the amount of the Commitment Increase. The Borrower shall provide prompt notice of
any proposed Commitment Increase pursuant to this Section 2.6(d) to the Agent, which shall promptly provide a copy of such notice to the Lenders; 
 (ii) Any Commitment Increase shall become effective upon (A) the receipt by the Agent of (1) an agreement in form and substance
satisfactory to the Agent signed by the Borrower, each Increasing Lender and each Additional Lender, setting forth the new Commitment of each such Lender and setting forth the agreement of each Additional Lender to become a party to this Agreement
and to be bound by all the terms and provisions hereof binding upon each Lender, and (2) certified copies of the Commitment Increase Approvals and such opinions of counsel for the Borrower with respect to the Commitment Increase as the Agent
may reasonably request, (B) the funding by each Lender of the Advance(s) to be made by each such Lender described in paragraph (iii) below and (C) receipt by the Agent of a certificate (the statements contained in which shall be true)
of a duly authorized officer of the Borrower stating that both before and after giving effect to such Commitment Increase (1) no Event of Default has occurred and is continuing, (2) all representations and warranties made by such Borrower
in this Agreement are true and correct in all material respects, and (3) all Commitment Increase Approvals have been obtained and are in full force and effect. 
 (iii) Upon the effective date of any Commitment Increase, to the extent necessary to keep the outstanding Advances ratable in the event of
any non-ratable increase in Aggregate Commitment, (A) all then outstanding Eurodollar Rate Advances (the “Initial Advances”) shall automatically be converted into Base Rate Advances, (B) immediately after the
effectiveness of the Commitment Increase, the Borrower shall, if it so requests, convert such Base Rate Advances into Eurodollar Rate Advances (the “Subsequent Advances”) in an aggregate principal amount equal to the
aggregate principal amount of the Initial Advances and of the Types and for the Interest Periods specified in a Notice of Conversion delivered to the Agent in accordance with Section 2.11, (C) each Lender shall pay to the
Agent in immediately available funds an amount equal to the difference, if positive, between (y) such Lender’s Percentage (calculated after giving effect to the Commitment Increase) of the Subsequent Advances and (z) such
Lender’s Percentage (calculated without giving effect to the Commitment Increase) of the Initial Advances, (D) after the Agent receives the funds specified in clause (C) above, the 

  

 28 

 
Agent shall pay to each Lender the portion of such funds equal to the difference, if positive, between (y) such Lender’s Percentage (calculated
without giving effect to the Commitment Increase) of the Initial Advances and (z) such Lender’s Percentage (calculated after giving effect to the Commitment Increase) of the amount of the Subsequent Advances, (E) the Lenders shall be
deemed to hold the Subsequent Advances ratably in accordance with their respective Commitment (calculated after giving effect to the Commitment Increase), (F) the Borrower shall pay all accrued but unpaid interest on the Initial Advances to the
Lenders entitled thereto, and (G) Schedule I shall automatically be amended to reflect the Commitments of all Lenders after giving effect to the Commitment Increase. The conversion of the Initial Advances pursuant to clause (A) above
shall be subject to indemnification by the Borrower pursuant to the provisions of Section 8.4(b) if the date of any Commitment Increase occurs other than on the last day of the Interest Period relating thereto. 
 (iv) Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase and the making of
any Advances on such date pursuant to this Section 2.6(d), all calculations and payments of the Facility Fee and the LC Fee and of interest on the Advances shall take into account the actual Commitment of each Lender and such
Lender’s Percentage of the Outstanding Credits during the relevant period of time. 
 Section 2.7    Repayment
of Advances. 
 (a) Except to the extent due or paid sooner pursuant to the provisions of this Agreement, the Borrower shall repay to
the Lenders the aggregate outstanding principal amount of each Revolving Advance on the Termination Date and the aggregate outstanding principal amount of the Term Loans, if any, shall be due and payable in full on the Maturity Date. 
 (b) Except to the extent due or paid sooner pursuant to the provisions of this Agreement, the Borrower shall repay to the Swingline Lender the aggregate
outstanding principal amount of each Swingline Advance on the earlier to occur of (i) fourteen (14) days after the date of Borrowing of each such Swingline Advance, and (ii) the Swingline Termination Date. 
 Section 2.8    Interest on Advances. The Borrower shall pay interest on the unpaid principal amount of each Advance
owing to each Lender from the date of such Advance until such principal amount shall be paid in full, at the Applicable Rate for such Advance (except as otherwise provided in this Section 2.8), payable as follows: 
 (a) If such Advance is a Base Rate Advance, interest thereon shall be payable quarterly in arrears on the last day of each March, June, September and
December, on the date of any Conversion of such Base Rate Advance and on the date such Base Rate Advance shall become due and payable or shall otherwise be paid in full; provided that at any time an Event of Default shall have occurred and be
continuing, each Base Rate Advance shall bear interest payable on demand, at a rate per annum equal at all times to the Default Rate. 
  

 29 

 (b) If such Advance is a Eurodollar Rate Advance, interest thereon shall be payable on the last day of
such Interest Period and, if the Interest Period for such Advance has a duration of more than three months, on that day of each third month during such Interest Period that corresponds to the first day of such Interest Period (or, if any such month
does not have a corresponding day, then on the last day of such month); provided that at any time an Event of Default shall have occurred and be continuing, each Eurodollar Rate Advance shall bear interest payable on demand, at a rate per
annum equal at all times to the Default Rate. 
 (c) If such Advance is a LIBOR Market Index Rate Advance, interest thereon shall be
payable in arrears on the last day of each March, June, September and December, and on the date such LIBOR Market Index Rate Advance shall become due and payable or shall otherwise be paid in full; provided that at any time an Event of
Default shall have occurred and be continuing, each LIBOR Market Index Rate Advance shall bear interest payable on demand, at a rate per annum equal at all times to the Default Rate. 
 (d) In respect of any Advance, interest thereon shall be payable at the Applicable Rate at maturity (whether pursuant to acceleration or otherwise) and,
after maturity, on demand. 
 (e) Nothing contained in this Agreement or in any other Loan Document shall be deemed to establish or require
the payment of interest to any Lender at a rate in excess of the maximum rate permitted by applicable law. If the amount of interest payable for the account of any Lender on any interest payment date would exceed the maximum amount permitted by
applicable law to be charged by such Lender, the amount of interest payable for its account on such interest payment date shall be automatically reduced to such maximum permissible amount. In the event of any such reduction affecting any Lender, if
from time to time thereafter the amount of interest payable for the account of such Lender on any interest payment date would be less than the maximum amount permitted by applicable law to be charged by such Lender, then the amount of interest
payable for its account on such subsequent interest payment date shall be automatically increased to such maximum permissible amount, provided that at no time shall the aggregate amount by which interest paid for the account of any Lender has
been increased pursuant to this sentence exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant to the previous sentence. 
 Section 2.9    Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to Agent for the account of each
Lender any costs actually incurred by such Lender with respect to Eurodollar Rate Advances that are attributable to such Lender’s compliance with regulations of the Board of Governors of the Federal Reserve System requiring the maintenance of
reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities. Such costs shall be paid to the Agent for the account of such Lender in the form of additional interest on the unpaid principal amount of each
Eurodollar Rate Advance of such Lender, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the
Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest
is payable on such Advance. Such additional interest shall be determined by such Lender and notified to the Borrower through the Agent. A certificate as to the amount of such additional interest, submitted to the Borrower and the Agent by such
Lender, shall be conclusive and binding for all purposes, absent manifest error, provided that the determination thereof shall have been made by such Lender in good faith. 
  

 30 

 Section 2.10    Interest Rate Determination. 
 (a) Each Reference Bank agrees to furnish to the Agent timely information for the purpose of determining each Eurodollar Rate. If any one or more of the
Reference Banks shall not furnish such timely information to the Agent for the purpose of determining any such interest rate, the Agent shall determine such interest rate on the basis of timely information furnished by the remaining Reference Banks.

 (b) The Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Agent for
purposes of Section 2.8(a), Section 2.8(b) or Section 2.8(c), and the applicable rate, if any, furnished by each Reference Bank for the purpose of determining the applicable interest rate
under Section 2.8(b). 
 (c) If fewer than two Reference Banks furnish timely information to the Agent for determining the
Eurodollar Rate, due to the unavailability of funds to such Reference Banks in the relevant financial markets: 
 (i) the
Agent shall forthwith notify the Borrower and the Lenders that the interest rate cannot be determined for Eurodollar Rate Advances; 
 (ii) each such Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base Rate Advance (or if such Advance is then a Base Rate Advance, will continue as a Base Rate
Advance); and 
 (iii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be
suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist. 
 (d)
If, with respect to any Eurodollar Rate Advances, the Majority Lenders notify the Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect the cost to such Majority Lenders of making, funding or
maintaining their respective Eurodollar Rate Advances for such Interest Period, the Agent shall forthwith so notify the Borrower and the Lenders, whereupon: 
 (i) each Eurodollar Rate Advance will automatically, on the last day of the then existing Interest Period therefor, Convert into a Base
Rate Advance; and 
 (ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall
be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist. 
 (e)
If the Borrower shall fail to (i) select the duration of any Interest Period for any Eurodollar Rate Advance in accordance with the provisions contained in the definition of “Interest Period” in Section 1.1
or (ii) provide a Notice of Conversion with respect to any Eurodollar Rate Advance on or prior to 12:00 noon on the third Business Day prior to the last 

  

 31 

 
day of the Interest Period applicable thereto, the Agent will forthwith so notify the Borrower and the Lenders and such Advance will automatically, on the
last day of the then existing Interest Period therefor, Convert into a Base Rate Advance. 
 (f) On the date on which the aggregate unpaid
principal amount of Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than the product of (i) $1,000,000 and (ii) the number of Lenders on such date, such Advances shall, if they are
Advances of a Type other than Base Rate Advances, automatically Convert into Base Rate Advances, and on and after such date the right of the Borrower to Convert such Advances into Advances of a Type other than Base Rate Advances shall terminate;
provided, however, that if and so long as each such Advance shall be of the same Type and have the same Interest Period as Advances comprising another Borrowing or other Borrowings, and the aggregate unpaid principal amount of all such
Advances shall equal or exceed the product of (i) $1,000,000 and (ii) the number of Lenders on such date, the Borrower shall have the right to continue all such Advances as, or to Convert all such Advances into, Advances of such Type
having such Interest Period. 
 (g) Upon the occurrence and during the continuance of any Event of Default, each outstanding Eurodollar Rate
Advance shall automatically Convert into a Base Rate Advance at the end of the Interest Period then in effect for such Eurodollar Rate Advance. 
 Section 2.11    Voluntary Conversion of Advances. Subject to the conditions set forth below, the Borrower may, on any Business Day, by delivering a notice of Conversion (a “Notice of
Conversion”) to the Agent not later than 12:00 noon (i) on the third Business Day prior to the date of the proposed Conversion, in the case of a Conversion to or in respect of Eurodollar Rate Advances and (ii) on the date of
the proposed Conversion, in the case of a Conversion to or in respect of Base Rate Advances, and subject to the provisions of Section 2.10 and Section 2.15, Convert all Advances of one Type comprising the same
Borrowing into Advances of another Type; provided, however, that, in the case of any Conversion of any Eurodollar Rate Advances into Base Rate Advances on a day other than the last day of an Interest Period for such Eurodollar Rate
Advances, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.4(b). Each such Notice of Conversion shall be in substantially the form of Exhibit 2.11 and shall, within
the restrictions specified above, specify (A) the date of such Conversion, (B) the Advances to be Converted, (C) if such Conversion is into Eurodollar Rate Advances, the duration of the Interest Period for each such Advance, and
(D) the aggregate amount of Advances proposed to be Converted. Notwithstanding the foregoing, the Borrower may not Convert Base Rate Advances into Eurodollar Rate Advances and may not select a new Interest Period for Eurodollar Rate Advances at
any time an Event of Default has occurred and is continuing. 
 Section 2.12    Optional Prepayments of
Advances. The Borrower may, upon at least three Business Days’ notice to the Agent stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given, the Borrower shall prepay for the ratable
account of the Lenders the outstanding principal amounts of the Advances comprising part of the same Borrowing in whole or ratably in part, without premium or penalty, together with accrued interest to the date of such prepayment on the principal
amount prepaid; provided, however, that each partial prepayment shall be in an aggregate principal amount not less than $1,000,000 (or, if 
  

 32 

 
lower, the principal amount outstanding hereunder on the date of such prepayment) or an integral multiple of $1,000,000 in excess thereof. In the case of any
such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.4(b). Except as provided in this Section 2.12, the Borrower shall
have no right to prepay any principal amount of any Advances. 
 Section 2.13    Increased Costs. 

 (a) If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve
requirements, in the case of Eurodollar Rate Advances, included in the Eurodollar Rate Reserve Percentage) in or to the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other
governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding, or maintaining Eurodollar Rate Advances or to increase the cost to the Swingline Lender or
any Lender of participating in, issuing or maintaining any LIBOR Market Index Rate Advance (or of maintaining its obligations to participate in any LIBOR Market Index Rate Advance) or to increase the cost to such Lender or the LC Issuing Bank of
participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligations to participate in or to issue any Letter of Credit), then the Borrower shall from time to time, upon demand by such Lender, Swingline Lender or the LC
Issuing Bank (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender, Swingline Lender or LC Issuing Bank additional amounts sufficient to compensate such Lender, Swingline Lender or LC Issuing Bank for such
increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower and the Agent by such Lender, Swingline Lender or LC Issuing Bank, shall be conclusive and binding for all purposes, absent manifest error,
provided that the determination thereof shall have been made by such Lender, Swingline Lender or LC Issuing Bank in good faith. 
 (b)
If any Lender, the Swingline Lender or LC Issuing Bank determines that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would
affect the amount of capital required or expected to be maintained by such Lender, Swingline Lender or LC Issuing Bank or any corporation controlling such Lender, Swingline Lender or LC Issuing Bank and that the amount of such capital is increased
by or based upon the existence of such Lender’s commitment to lend or participate in LIBOR Market Index Rate Advances or Letters of Credit hereunder or the Swingline Lender’s obligation to issue or maintain any Swingline Advance or the LC
Issuing Bank’s obligation to issue or maintain any Letter of Credit hereunder and other commitments of this type, then, upon demand by such Lender, Swingline Lender or LC Issuing Bank (with a copy of such demand to the Agent), the Borrower
shall immediately pay to the Agent for the account of such Lender, Swingline Lender or LC Issuing Bank, from time to time as specified by such Lender, Swingline Lender or LC Issuing Bank, additional amounts sufficient to compensate such Lender,
Swingline Lender or LC Issuing Bank or such corporation in the light of such circumstances, to the extent that such Lender, Swingline Lender or LC Issuing Bank reasonably determines such increase in capital to be allocable to the existence of such
Lender’s Commitment, Swingline Lender’s obligations hereunder or LC Issuing Bank’s obligations hereunder. A certificate as to such amounts submitted to the Borrower and the Agent by such Lender, Swingline Lender or LC Issuing Bank,
describing in reasonable detail the 

  

 33 

 
manner in which such amounts have been calculated, shall be conclusive and binding for all purposes, absent manifest error, provided that the
determination and allocation thereof shall have been made by such Lender, Swingline Lender or LC Issuing Bank in good faith. 
 (c)
Notwithstanding any provision of Section 2.13(a) or Section 2.13(b) to the contrary, no Lender, Swingline Lender or LC Issuing Bank shall be entitled to demand compensation or be compensated thereunder to the
extent that such compensation relates to any period of time more than 60 days prior to the date upon which such Lender, Swingline Lender or LC Issuing Bank first notified the Borrower of the occurrence of the event entitling such Lender, Swingline
Lender or LC Issuing Bank 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 Borrower). 
 Section 2.14    Illegality. Notwithstanding any other provision of this Agreement to the contrary, if any Lender (the
“Affected Lender”) shall notify the Agent and the Borrower that the introduction of or any change in or to the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority
asserts that it is unlawful, for the Affected Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, all Eurodollar Rate Advances of
the Affected Lender shall, on the fifth Business Day following such notice from the Affected Lender, automatically be Converted into a like number of Base Rate Advances, each in the amount of the corresponding Eurodollar Rate Advance of the Affected
Lender being so Converted (each such Advance, as so Converted, being an “Affected Lender Advance”), and the obligation of the Affected Lender to make, maintain, or Convert Advances into Eurodollar Rate Advances shall
thereupon be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, or the Affected Lender has been replaced pursuant to Section 8.7(g). For purposes of
any prepayment under this Agreement, each Affected Lender Advance shall be deemed to continue to be part of the same Borrowing as the Eurodollar Rate Advances to which it corresponded at the time of the Conversion of such Affected Lender Advance
pursuant to this Section 2.14. 
 Section 2.15    Payments and Computations.

 (a) The Borrower shall make each payment hereunder not later than 1:00 p.m. on the day when due in Dollars to the Agent at its
address referred to in Section 8.2 in same day funds. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or fees ratably (other than amounts payable pursuant to
Section 2.9, Section 2.17, Section 2.19 or Section 8.4(b)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the
payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of a Lender Assignment and recording of
the information contained therein in the Register pursuant to Section 8.7(d), from and after the effective date specified in such Lender Assignment, the Agent shall make all payments hereunder in respect of the interest assigned
thereby to the Lender assignee thereunder, and the parties to such Lender Assignment shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. 
  

 34 

 (b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not
made when due hereunder held by such Lender, to charge from time to time against any or all of the Borrower’s accounts with such Lender any amount so due. 
 (c) All computations of interest based on clause (i) of the definition of “Alternate Base Rate” and of the Facility Fees shall be made by the Agent on the basis of a year of 365 or 366
days, as the case may be, and all computations of interest based on the Eurodollar Rate, LIBOR Market Index Rate and the LC Fee and the Federal Funds Rate shall be made by the Agent, and all computations of interest pursuant to
Section 2.10 shall be made by a Lender, on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees
are payable. Each determination by the Agent (or, in the case of Section 2.10, by a Lender) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error, provided that such
determination shall have been made by the Agent or such Lender, as the case may be, in good faith. 
 (d) Whenever any payment hereunder
shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case
may be; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the immediately preceding
Business Day. 
 (e) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the
Lenders hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to
each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount
distributed to such Lender together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate. 
 Section 2.16    Noteless Agreement; Evidence of Indebtedness. 
 (a) 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 Advance made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. 
 (b) The Agent shall also maintain accounts in which it will record (i) the amount of each Advance made hereunder, the Class and Type thereof and the
Interest Period (if any) with respect 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 Agent
hereunder from the Borrower and each Lender’s share thereof. 
  

 35 

 (c) The entries maintained in the accounts maintained pursuant to Section 2.16(a) and
Section 2.16(b) shall be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay such obligations in accordance with their terms. 
 (d) The
Advances of each Class made by each Lender shall, if requested by the applicable Lender (which request shall be made to the Agent), be evidenced (i) in the case of Term Loans, if the Borrower has exercised its Term-Out Option, by a Term Note,
(ii) in the case of Revolving Advances, by a Revolving Note, and (iii) in the case of the Swingline Advances, by a Swingline Note, in each case appropriately completed and executed by the Borrower and payable to the order of such Lender.
Each Note shall be entitled to all of the benefits of this Agreement and the other Loan Documents and shall be subject to the provisions hereof and thereof. 
 Section 2.17    Taxes. 
 (a) Any and all payments by the Borrower
hereunder and under the other Loan Documents shall be made, in accordance with Section 2.15, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding, in the case of each Lender, the LC Issuing Bank and the Agent, taxes imposed on its overall net income and franchise taxes imposed on it by any jurisdiction, unless such Lender, the LC
Issuing Bank or the Agent (as the case may be) would not have had such taxes imposed on it by such jurisdiction but for such Lender’s, the LC Issuing Bank’s or the Agent’s (as the case may be) having entered into this Agreement,
having consummated the transactions contemplated hereby or having received payments by the Borrower hereunder or under the other Loan Documents (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Lender, the LC Issuing Bank or the
Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.17) such Lender, the LC Issuing
Bank 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 Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to
the relevant taxation authority or other authority in accordance with applicable law. 
 (b) In addition, the Borrower agrees to pay any
present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any other Loan Document or from the execution, delivery or registration of, or
otherwise with respect to, this Agreement or any other Loan Document (hereinafter referred to as “Other Taxes”). 
 (c) The Borrower will indemnify each Lender, the LC Issuing Bank and the Agent for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.17) paid by such Lender, the LC Issuing Bank or the Agent (as the case may be) and any liability (including penalties, 

  

 36 

 
interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This
indemnification shall be made within 30 days from the date such Lender, the LC Issuing Bank or the Agent (as the case may be) makes written demand therefor. Nothing herein shall preclude the right of the Borrower to contest any such Taxes or Other
Taxes so paid, and the Lenders in question, the LC Issuing Bank or the Agent (as the case may be) will, following notice from, and at the expense of, the Borrower, reasonably cooperate with the Borrower to preserve the Borrower’s rights to
contest such Taxes or Other Taxes. 
 (d) Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at
its address referred to in Section 8.2, the original or a certified copy of a receipt evidencing payment thereof. 
 (e)
The LC Issuing Bank and each Lender agrees that, on or prior to the date upon which it shall become a party hereto, and upon the reasonable request from time to time of the Borrower or the Agent, the LC Issuing Bank or such Lender will deliver to
the Borrower and the Agent either (i) a statement that it is organized under the laws of a jurisdiction within the United States or (ii) duly completed copies of such form or forms as may from time to time be prescribed by the United
States Internal Revenue Service indicating that the LC Issuing Bank or such Lender is entitled to receive payments without deduction or withholding of any United States federal income taxes, as permitted by the Internal Revenue Code of 1986, as
amended from time to time. The LC Issuing Bank and each Lender that delivers to the Borrower and the Agent the form or forms referred to in the preceding sentence further undertakes to deliver to the Borrower and the Agent further copies of such
form or forms, or successor applicable form or forms, as the case may be, as and when any previous form filed by it hereunder shall expire or shall become incomplete or inaccurate in any respect. The LC Issuing Bank and each Lender represents and
warrants that each such form supplied by it to the Agent and the Borrower pursuant to this Section 2.17(e), and not superseded by another form supplied by it, is or will be, as the case may be, complete and accurate. 

(f) Any Lender claiming any additional amounts payable pursuant to this Section 2.17 shall use reasonable efforts (consistent with
its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter
accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. 
 (g) Without prejudice to the
survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.17 shall survive the payment in full of principal and interest hereunder. 
 Section 2.18     Sharing of Payments, Etc. All payments from or on behalf of the Borrower on account of
any obligations shall be apportioned ratably among the Lenders based upon their respective share, if any, of the obligations with respect to which such payment was received. If any Lender shall obtain any payment (whether voluntary, involuntary,
through the exercise of any right of set off, or otherwise) on account of the Advances made by it (other than pursuant to Section 2.9, Section 2.13, Section 2.17, Section 2.19
or Section 8.4(b)) or on 

  

 37 

 
account of the Borrower’s reimbursement obligations in respect of LC Outstandings in excess of its ratable share of payments obtained by all the Lenders
on account of the Advances or on account of such reimbursement obligations, such Lender shall forthwith purchase from the other Lenders such participations in the Advances made by them and such reimbursement obligations as shall be necessary to
cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each
Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount
of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees
that any Lender so purchasing a participation from another Lender pursuant to this Section 2.18 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set off) with respect to such participation
as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation. 
 Section 2.19    Extension of Termination Date. 
 (a) So long as no Unmatured Default or Event
of Default has occurred and is continuing and subject to the conditions set forth in Section 2.19(c), the Borrower may, no earlier than 60 days and no later than 30 days prior to each anniversary of the Amendment Effective Date
(such anniversary, an “Extension Date”), but on no more than two occasions, request through written notice to the Agent (the “Extension Notice”), that the Lenders extend the then existing Termination
Date for an additional one-year period. Each Lender, acting in its sole discretion, shall, by notice to the Agent no later than the applicable Extension Date (except in the year in which the then existing Termination Date shall occur, in which case
such written notice shall be delivered by the Lenders no later than 15 days prior to the then existing Termination Date) (such date, the “Consent Date”), advise the Agent in writing of its desire to extend (any such Lender, a
“Consenting Lender”) or not to so extend (any such Lender, a “Non-Consenting Lender”) such date. Any Lender that does not advise the Agent by the Consent Date shall be deemed to be a Non-Consenting
Lender. No Lender shall be under any obligation or commitment to extend the then existing Termination Date. The election of any Lender to agree to such extension shall not obligate any other Lender to agree to such extension. 
 (b) If Lenders holding a Commitment that aggregate more than 50% of the Aggregate Commitment on the Consent Date shall have agreed to such extension,
then the then existing Termination Date applicable to the Consenting Lenders shall be extended to the date that is one year after the then existing Termination Date. All Advances of each Non-Consenting Lender shall be subject to the then existing
Termination Date, without giving effect to such extension (such date, the “Prior Termination Date”). In the event of an extension of the then existing Termination Date pursuant to this Section 2.19, the
Borrower shall have the right, at its own expense, to solicit commitments from existing Lenders and/or Eligible Assignees reasonably acceptable to the Agent and the LC Issuing Bank to replace the Commitment of any Non-Consenting Lenders for the
remaining duration of this Agreement. Any Eligible Assignee (if not already a Lender hereunder) shall become a party to this Agreement as a Lender pursuant to a joinder agreement in form and substance reasonably satisfactory to the Agent and the
Borrower.

The Commitment of each Non-Consenting Lender shall terminate on the Prior Termination Date, all Advances and other amounts payable hereunder to such
Non-Consenting Lenders shall be subject to the Prior Termination Date and, to the extent such Non-Consenting Lender’s Commitment is not replaced as provided above, the Aggregate Commitment hereunder shall be reduced by the amount of the
Commitment of each such Non-Consenting Lender so terminated on the Prior Termination Date. Notwithstanding anything to the contrary in this Section 2.19, the Termination Date shall not be extended unless the aggregate Commitments
of the Consenting Lenders and any Eligible Assignees joining this Agreement pursuant to this Section 2.19(b) are greater than or equal to the Outstanding Credits as of each Prior Termination Date. 
 (c) An extension of the Termination Date pursuant to this Section 2.19 shall only become effective upon the receipt by the Agent of a
certificate (the statements contained in which shall be true) of a duly authorized officer of the Borrower stating that both before and after giving effect to such extension of the Termination Date (i) no Event of Default has occurred and is
continuing and (ii) all representations and warranties contained in Section 4.1 are true and correct in all material respects on and as of the date such extension is made, except for such representations or warranties which
by their terms are made as of a specified date, which shall be true and correct as of such specified date. 
 (d) Effective on and after the
Prior Termination Date, (i) each of the Non-Consenting Lenders shall be automatically released from their respective participations and reimbursement obligations under Section 2.4 with respect to any LC Outstandings and
(ii) the participations and reimbursement obligations of each Lender (other than the Non-Consenting Lenders) shall be automatically adjusted to equal such Lender’s Percentage of such LC Outstandings. 
 Section 2.20    Replacement of Lenders. 
 (a) The Borrower may, at any time at its sole expense and effort, require any Lender that does not approve a consent, waiver or amendment to any Loan
Document requested by the Borrower or the Agent and that requires the approval of all Lenders under Section 8.1 which is otherwise approved by the Majority Lenders, upon notice to such Lender and the Agent, to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 8.7), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an
assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that: 
 (i) no Unmatured Default or Event of Default shall have occurred and be continuing at such time; 
 (ii) the Agent shall have received the assignment fee specified in Section 8.7(a); 
 (iii) such
Lender shall have received payment of an amount equal to the outstanding principal of its Advances and any funded participations in Letters of Credit not refinanced through the Borrowing of Revolving Advances, accrued interest thereon, accrued fees
and all other amounts payable to it hereunder and under the other Loan

Documents (including any amounts under Section 8.4(b)) from the assignee (to the extent of such outstanding principal and accrued interest
and fees) or the Borrower (in the case of all other amounts); 
 (iv) such assignee, if it is not an existing Lender and/or
Eligible Assignee, shall be reasonably satisfactory to the Agent; and 
 (v) such assignment does not conflict with any
applicable laws, rules, regulations and orders of any governmental authority or otherwise require any Governmental Approvals. 
 A Lender shall not be
required to make any assignment or delegation if, prior thereto, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

 ARTICLE VII 
 THE AGENT 
 Section 7.1    Authorization and Action. Each of
the Lenders (for purposes of this Article, references to the Lenders shall also mean the LC Issuing Bank and the Swingline Lender) hereby appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under
this Agreement as are delegated to the Agent by the terms hereof, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement or any other Loan Document (including, without
limitation, enforcement or collection of the Borrowings), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Majority Lenders, and such instructions shall be binding upon all Lenders and all holders of Notes (if any); provided, however, that the
Agent shall not be required to take any action which, in its opinion or the opinion of its counsel, may expose the Agent to personal liability or which is contrary to this Agreement or applicable law. The Agent agrees to give to each Lender prompt
notice of each notice given to it by the Borrower pursuant to the terms of this Agreement. The Agent shall be deemed to have exercised reasonable care in the administration and enforcement of this Agreement and the other Loan Documents if it
undertakes such administration and enforcement in a manner substantially equal to that which Wachovia accords credit facilities similar to the credit facility hereunder for which it is the sole lender. The provisions of this Article are solely for
the benefit of the Agent and the Lenders except as otherwise expressly provided herein, and the Borrower shall have no rights as a third party beneficiary of any of such provisions. 
 Section 7.2     Agent’s Reliance, Etc. Neither the Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement or any other Loan Document, except for its or their own gross negligence or willful misconduct. Without limitation of the generality
of the foregoing, the Agent: (i) may treat the payee of any Note as the holder thereof until the Agent receives and accepts a Lender Assignment entered into by the Lender which is the payee of such Note, as assignor, and an Eligible Assignee,
as assignee, as provided in Section 8.7; (ii) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken
or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties
or representations (whether written or oral) made in or in connection with this Agreement or any other Loan Document; (iv) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or
conditions of this Agreement or any other Loan Document on the part of the Borrower or to inspect the property (including the books and records) of the Borrower; (v) shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto or thereto; and (vi) shall incur no liability under or in respect of this
Agreement or any other Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or
parties. 
  

 56 

 Section 7.3    Wachovia and Affiliates. With respect to its Commitment
and the Advances made by it, Wachovia shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Agent or the LC Issuing Bank; and the term “Bank” or “Banks”
and “Lender” or “Lenders” shall, unless otherwise expressly indicated, include Wachovia in its individual capacity. Wachovia and its Affiliates may accept deposits from, lend money to, act as the financial advisor or the trustee
under indentures of, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof and any Person who may do business with or own securities of the Borrower or any Subsidiary or other Affiliate thereof,
all as if Wachovia were not the Agent and without any duty to account therefor to the Lenders. 
 Section
7.4    Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on the financial statements referred to in Section 4.1(f)
and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or
any other Lender 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. 
 Section 7.5    Indemnification. The Lenders agree to indemnify the Agent and any Related Party of the Agent
participating in the transaction (to the extent not reimbursed by the Borrower), ratably according to (i) on or before the Maturity Date, the respective Percentages of the Lenders, or (ii) after the Maturity Date, the respective
outstanding principal amounts of the Advances, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or 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 action taken or omitted by the Agent under this Agreement, provided that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the
Agent promptly upon demand for its ratable share of any out of pocket expenses (including counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether
through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower. 
 Section 7.6    Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and
the Borrower and may be removed at any time with or without cause by the Majority Lenders, with any such resignation or removal to become effective only upon the appointment of a successor Agent pursuant to this Section 7.6. Upon
any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Agent, which shall be a Lender or shall be another commercial bank or trust company (and reasonably 

  

 57 

 
acceptable to the Borrower so long as no Event of Default exists) organized under the laws of the United States or of any State thereof. If no successor
Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Agent, then
the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a Lender or shall be another commercial bank or trust company organized under the laws of the United States of any State thereof reasonably acceptable to the
Borrower. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon 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 under this Agreement. After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of this Article VII shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Agent under this Agreement. 
 Section 7.7    Delegation of Duties.
The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Agent; provided, however, that the Agent
shall remain responsible for the performance of its duties under this Agreement and the Loan Documents to the extent required under this Article. The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and
powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Affiliates and the partners, directors, officers, employees, agents and advisors of the Agent and any such
sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as the Agent. 
 Section 7.8    No Other Duties, Etc. Anything herein to the contrary notwithstanding, none of the
Joint Lead Arrangers, Syndication Agent, Documentation Agents or other agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as
applicable, as the Agent or a Lender hereunder. 
 Section 7.9    LC Issuing Bank and Swingline
Lender. The provisions of this Article (other than Section 7.3) shall apply to the LC Issuing Bank and Swingline Lender mutatis mutandis to the same extent as such provisions apply to the
Agent. 
 ARTICLE VIII 
 MISCELLANEOUS 
 Section 8.1    Amendments, Etc. No amendment or
waiver of any provision of any Loan Document, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Majority Lenders and, in the case of any amendment, the
Borrower, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by all
the Lenders, do any of the following: (a) waive, modify or eliminate any of the conditions specified in Section 3.1 or 

  

 58 

 
Section 3.2; (b) increase or extend the Commitments of the Lenders (other than pursuant to

Section 2.17), (d) postpone any date fixed for any payment of principal of, or interest on, the Advances (excluding the conversion of Revolving Advances into Term Loans under
Section 2.1(c)), any reimbursement obligation in respect of Letters of Credit or any fees or other amounts payable hereunder, (e) change the percentage of the Commitments or of the aggregate unpaid principal
amount of the Advances, or the number of Lenders, which shall be required for the Lenders or any of them to take any action hereunder, (f) amend this Section 8.1, (g) release any collateral for the
obligations of the Borrower hereunder or (h) change or waive any provision of Section 2.18 or any other provision of this Agreement or any other Loan Document requiring pro rata treatment of the Lenders; and
provided, further, that (i) no amendment, waiver or consent shall affect the rights or duties of the Agent, the Swingline Lender or the LC Issuing Bank under this Agreement or any Note, unless such amendment, waiver or consent is
in writing and signed by the Agent, the Swingline Lender and the LC Issuing Bank, as the case may be, in addition to the Lenders required above to take such action, (ii) that no amendment, waiver or consent shall change or waive any provision
of Section 2.13 or Section 2.17, unless such amendment, waiver or consent is in writing and signed by each Lender directly affected thereby, in addition to the Lenders required above

LC Issuing Bank or the Agent, as the case may be, shall no longer be a party to this Agreement (as so amended and restated) or have any Commitment or other obligation hereunder or under any Letter of Credit and shall have been paid in full all
amounts payable hereunder to such Lender, the Swingline Lender, the LC Issuing Bank or the Agent, as the case may be.

on the part of any Lender, the Swingline Lender, the LC Issuing Bank or the Agent to exercise, and no delay in exercising, any right hereunder or under any Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such

connection with the enforcement of rights under this Section 8.4(a). In addition, the Borrower shall pay any and all stamp and other taxes payable or determined to be payable in connection with the execution and delivery of this
Agreement and the other Loan Documents, and the other documents and instruments to be delivered hereunder and thereunder, and agrees to save the Agent, the LC Issuing Bank and each Lender harmless from and against any and all liabilities with
respect to or resulting from any delay in paying or omission to pay such taxes. 
 (b) If any payment of principal of, or Conversion of, any
Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance as a result of a payment or Conversion pursuant to Section 2.6(d), Section 2.10(f),
Section 2.11, Section 2.12 or Section 2.14 or acceleration of the maturity of the Advances pursuant to Section 6.1 or for any other reason, the Borrower shall, upon demand
by any Lender or the LC Issuing Bank (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender or the LC Issuing Bank, as the case may be, any amounts required to compensate such Lender or the LC Issuing Bank for any
additional losses, costs or expenses which it may reasonably incur as a result of such payment or Conversion, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by any Lender to fund or maintain such Advance. 
 (c) The Borrower hereby agrees to indemnify and hold each Lender, the Agent, the
Swingline Lender, the LC Issuing Bank and their respective officers, directors, employees, professional advisors and affiliates (each, an “Indemnified Person”) harmless from and against 

  

 60 

 
any and all claims, damages, losses, liabilities, costs or expenses (including reasonable attorney’s fees and expenses, whether or not such Indemnified
Person is named as a party to any proceeding or is otherwise subjected to judicial or legal process arising from any such proceeding) which any of them may incur or which may be claimed against any of them by any Person including the Borrower
(except for such claims, damages, losses, liabilities, costs and expenses resulting from such Indemnified Person’s gross negligence or willful misconduct): 
 (i) by reason of or resulting from the execution, delivery or performance of any of the Loan Documents or any transaction contemplated
thereby, or the use by the Borrower of the proceeds of any Advance or the use by the Borrower or any beneficiary of any Letter of Credit of such Letter of Credit; 
 (ii) in connection with any documentary taxes, assessments or charges made by any governmental authority by reason of the execution and
delivery of any of the Loan Documents; 
 (iii) in connection with or resulting from the utilization, storage, disposal,
treatment, generation, transportation, release or ownership of any Hazardous Substance (A) at, upon, or under any property of the Borrower or any of its Affiliates or (B) by or on behalf of the Borrower or any of its Affiliates at any time
and in any place; or 
 (iv) in connection with or resulting from the use by unintended recipients of any information or other
materials distributed by it through the internet, SyndTrak or other similar transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby. 
 In case any action or proceeding is instituted involving any Indemnified Person for which indemnification is to be sought hereunder by
such Indemnified Person, then such Indemnified Person will promptly notify the Borrower of the commencement of any action or proceeding; provided, however, that the failure so to notify the Borrower will not relieve the Borrower from
any liability that the Borrower may have to such Indemnified Person pursuant hereto or from any liability that it may have to such Indemnified Person other than pursuant hereto. Notwithstanding the above, following such notification, the Borrower
may elect in writing to assume the defense of such action or proceeding, and, upon such election, the Borrower will not, as long as it diligently conducts such defense, be liable for any legal costs subsequently incurred by such Indemnified Person
(other than reasonable costs of investigation and providing evidence) in connection therewith, unless (i) the Borrower has failed to provide counsel reasonably satisfactory to such Indemnified Person in a timely manner (it being agreed that
Foley & Lardner LLP shall be deemed to be reasonably satisfactory counsel for such purpose), (ii) the Indemnified Person determines in good faith that joint representation would be inappropriate or (iii) the Indemnified Person
reasonably determines that there may be legal defenses available to it which are different from, or in addition to those available to the Borrower. If the Borrower assumes the defense of any such action or proceeding, (a) it will be
conclusively established for purposes of this Agreement that the claims made with respect thereto are subject to indemnification hereunder; (b) no compromise or settlement of such claims may be effected by the Borrower without the Indemnified

  

 61 

 
Person’s consent and (c) the Indemnified Person will have no liability with respect to any compromise or settlement of such claims effected without
its consent. Notwithstanding the foregoing, if any Indemnified Person determines in good faith that there is a reasonable probability that any action or proceeding may adversely affect it or its affiliates other than as a result of monetary damages
for which it would be entitled to indemnification hereunder, such Indemnified Person many, by notice to the Borrower, assume the exclusive right to defend, compromise, or settle such action or proceeding, but the Borrower will not be bound (but will
retain its indemnification obligations hereunder) by any determination of an action or proceeding so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld). In connection with any one action or
proceeding, the Borrower will not be responsible for the fees and expenses of more than one separate law firm (in addition to local counsel) for all Indemnified Persons. 
 (d) The Borrower’s obligations under this Section 8.4 shall survive the repayment of all amounts owing to the Lenders hereunder and the termination of the Commitments. If and to the extent that
the obligations of the Borrower under this Section 8.4 are unenforceable for any reason, the Borrower agrees to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law.

 Section 8.5    Right of Set-off. 
 (a) Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent
by the Majority Lenders specified by Section 6.1 to authorize the Agent to declare all amounts owing hereunder due and payable pursuant to the provisions of Section 6.1, each Lender is hereby authorized at any
time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender to or
for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under any Loan Document, irrespective of whether or not such Lender shall have made any demand under such Loan Document
and although such obligations may be unmatured. Each Lender agrees promptly to notify the Borrower after any such set-off and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such
set off and application. The rights of each Lender under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which such Lender may have. 
 (b) The Borrower agrees that it shall have no right of set-off, deduction or counterclaim in respect of its obligations hereunder, and that the
obligations of the Lenders hereunder are several and not joint. Nothing contained herein shall constitute a relinquishment or waiver of the Borrower’s rights to any independent claim that the Borrower may have against the Agent, the LC Issuing
Bank or any Lender for the Agent’s, the LC Issuing Bank’s or such Lender’s, as the case may be, gross negligence or willful misconduct; provided that no Lender shall be liable for the conduct of the Agent, the LC Issuing Bank
or any other Lender; provided, further, that the Agent shall not be liable for the conduct of any Lender or the LC Issuing Bank, and the LC Issuing Bank shall not be liable for the conduct of any Lender or the Agent; provided,
however that none of the Agent, any Lender or the LC Issuing Bank shall be liable to the Borrower for any amounts representing indirect, special, consequential or punitive damages suffered by the Borrower. 
  

 62 

 Section 8.6    Binding Effect. This Agreement shall become
effective when it shall have been executed by the Borrower and the Agent and when the Agent shall have been notified in writing by each Bank that such Bank has executed it and thereafter shall be binding upon and inure to the benefit of the
Borrower, the Agent, the LC Issuing Bank and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the
Lenders. 
 Section 8.7    Assignments and Participations. 
 (a) Each Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under the Loan Documents (including, without
limitation, all or a portion of its Commitment, the Advances owing to it, its participations in Letters of Credit and Swingline Advances, and the Note or Notes (if any) held by it); provided, however, that (i) each such assignment
shall be of a constant, and not a varying, percentage of all of the assigning Lender’s rights and obligations under the Loan Documents, (ii) the amount of the Commitment of the assigning Lender being assigned pursuant to each such
assignment (determined as of the date of the Lender Assignment with respect to such assignment) shall in no event be less than the lesser of the amount of such Lender’s then remaining Commitment and $5,000,000 or any whole multiple of
$1,000,000 in excess thereof (except in the case of assignments between Lenders at the time already parties hereto and between a Lender and an Affiliate of such Lender), (iii) the Agent, the LC Issuing Bank and, so long as no Event of Default
shall have occurred and be continuing, the Borrower, shall have consented to such assignment (in each case, which may not be unreasonably withheld or delayed), and (iv) the parties to each such assignment shall execute and deliver to the Agent,
for its acceptance and recording in the Register, a Lender Assignment, together with any Note or Notes (if any) subject to such assignment and a processing and recordation fee of $3,500. Promptly following its receipt of such Lender Assignment, Note
or Notes (if any) and fee, the Agent shall accept and record such Lender Assignment in the Register. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Lender Assignment, (x) the
assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Lender Assignment, have the rights and obligations of a Lender hereunder and (y) the Lender assignor
thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Lender Assignment, relinquish its rights and be released from its obligations under this Agreement (and, in the case of a Lender
Assignment covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto, but shall continue to be entitled to the benefits of
Section 2.13(a), Section 2.13(b), Section 2.17, and Section 8.4 with respect to facts and circumstances occurring prior to the effective date of such assignment).
Notwithstanding anything to the contrary contained in this Agreement, any Lender may at any time, with notice to the Borrower, the Agent and the LC Issuing Bank, assign all or any portion of the Advances owing to it to any other Lender or any
Affiliate of a Lender. No such assignment, other than to an Eligible Assignee, a Lender or an Affiliate of a Lender, shall release the assigning Lender from its obligations hereunder. 
  

 63 

 (b) By executing and delivering a Lender Assignment, the Lender assignor thereunder and the assignee
thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Lender Assignment, such assigning Lender makes no representation or warranty and assumes no responsibility with respect
to any statements, warranties or representations made in or in connection with any Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any other instrument or document
furnished pursuant thereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its
obligations under any Loan Document or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of each Loan Document, together with copies of the financial statements referred to in
Section 4.1(f)) hereof and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Lender Assignment; (iv) such assignee will, independently and
without reliance upon the Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan
Documents; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to
the Agent by the terms thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Loan Documents
are required to be performed by it as a Lender. 
 (c) The Agent shall maintain at its address referred to in Section 8.2
a copy of each Lender Assignment delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Advances owing to, each Lender from time to time (the
“Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a
Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice. 
 (d) Upon its receipt of a Lender Assignment executed by an assigning Lender and an assignee representing that it is an Eligible Assignee, together with
any Note or Notes (if any) subject to such assignment, the Agent shall, if such Lender Assignment has been completed and is in substantially the form of Exhibit 8.7 hereto, (i) accept such Lender Assignment, (ii) record the
information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. 
 (e) Each Lender may sell
participations to one or more banks, financial institutions or other entities in all or a portion of its rights and obligations under the Loan Documents (including, without limitation, all or a portion of its Commitment, the Advances owing to it,
its participations in Letters of Credit or Swingline Advances, and the Note or Notes (if any) held by it); provided, however, that (i) such Lender’s obligations under this Agreement (including, without limitation, its
Commitment to the Borrower hereunder) shall remain unchanged, (ii) such 

  

 64 

 
Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of
any such Note (if any) for all purposes of this Agreement, and (iv) the Borrower, the Agent and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under
this Agreement. 
 (f) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to
this Section 8.7, disclose to the assignee or participant or proposed assignee or participant, any information relating to the Borrower furnished to such Lender by or on behalf of the Borrower; provided that, prior to any
such disclosure, the assignee or participant or proposed assignee or participant shall agree, in accordance with the terms of Section 8.8, to preserve the confidentiality of any Confidential Information relating to the Borrower
received by it from such Lender. 
 (g) If any Lender (or any bank, financial institution, or other entity to which such Lender has sold a
participation) shall (i) make any demand for payment under Section 2.9, Section 2.13 or Section 2.17 or (ii) give notice to the Agent pursuant to Section 2.14,
then within 30 days after any such demand or occurrence (if, but only if, in the case of any demanded payment described in clause (i), such demanded payment has been made by the Borrower), the Borrower may, with the approval of the Agent and the LC
Issuing Bank (which approval shall not be unreasonably withheld), and provided that no Event of Default or Unmatured Default shall then have occurred and be continuing, demand that such Lender assign in accordance with this
Section 8.7 to one or more Eligible Assignees designated by the Borrower all (but not less than all) of such Lender’s Commitment, its participations in Letters of Credit and Swingline Advances and the Advances owing to it
within the period ending on the later to occur of (x) the last day in the 30-day period described above and (y) the last day of the longest of the then-current Interest Periods for such Advances. If any such Eligible Assignee designated by
the Borrower shall fail to consummate such assignment on terms acceptable to such Lender, or if the Borrower shall fail to designate any such Eligible Assignees for all or part of such Lender’s Commitment or Advances, then such demand by the
Borrower shall become ineffective; it being understood for purposes of this Section 8.7(g) that such assignment shall be conclusively deemed to be on terms acceptable to such Lender, and such Lender shall be compelled to
consummate such assignment to an Eligible Assignee designated by the Borrower, if such Eligible Assignee (1) shall agree to such assignment by entering into a Lender Assignment with such Lender and (2) shall offer compensation to such
Lender in an amount equal to all amounts then owing by the Borrower to such Lender hereunder, whether for principal, interest, fees, costs or expenses (other than the demanded payment referred to above and payable by the Borrower as a condition to
the Borrower’s right to demand such assignment), or otherwise. 
 (h) Anything in this Section 8.7 to the contrary
notwithstanding, any Lender may assign and pledge all or any portion of its Commitment and the Advances owing to it to any Federal Reserve Bank (and its transferees) as collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder. 
  

 65 

 (i) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting
Lender”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Lender identified as such in writing from time to time by the Granting Lender to the Agent, the LC Issuing Bank and the
Borrower, the option to provide to the Borrower all or any part of any Advance that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a
commitment by any such SPC to make any Advance, (ii) if such SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms
hereof and (iii) no SPC or Granting Lender shall be entitled to receive any greater amount pursuant to Section 2.13 or Section 8.4 than the Granting Lender would have been entitled to receive had the
Granting Lender not otherwise granted such SPC the option to provide any Advance to the Borrower. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Advance were made
by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would otherwise be liable so long as, and to the extent that, the related
Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day
after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against or join any other person in instituting against such SPC any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceedings under the laws of the United States or any State thereof. Notwithstanding the foregoing, the Granting Lender unconditionally agrees to indemnify the Borrower, the LC Issuing Bank, the Agent and each Lender against all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be incurred by or asserted against the Borrower, the LC Issuing Bank, the Agent or such
Lender, as the case may be, in any way relating to or arising as a consequence of any such forbearance or delay in the initiation of any such proceeding against its SPC. Each party hereto hereby acknowledges and agrees that no SPC shall have the
rights of a Lender hereunder, such rights being retained by the applicable Granting Lender. Accordingly, and without limiting the foregoing, each party hereby further acknowledges and agrees that no SPC shall have any voting rights hereunder and
that the voting rights attributable to any Advance made by an SPC shall be exercised only by the relevant Granting Lender and that each Granting Lender shall serve as the administrative agent and attorney-in-fact for its SPC and shall on behalf of
its SPC receive any and all payments made for the benefit of such SPC and take all actions hereunder to the extent, if any, such SPC shall have any rights hereunder. In addition, notwithstanding anything to the contrary contained in this Agreement
any SPC may (i) with notice to, but without the prior written consent of any other party hereto, assign all or a portion of its interest in any Advances to the Granting Lender and (ii) disclose on a confidential basis any information
relating to its Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section 8.7(i) may not be amended without the prior written consent
of each Granting Lender, all or any part of whose Advance is being funded by an SPC at the time of such amendment. 
 Section 8.8    Confidentiality. In connection with the negotiation and administration of this Agreement and the other Loan Documents, the Borrower has furnished and will from time to time furnish to
the Agent, the LC Issuing Bank and the Lenders (each, a “Recipient”) written 

  

 66 

 
information which is identified to the Recipient in writing, when delivered, as confidential (such information, other than any such information which
(i) as publicly available, or otherwise known to the Recipient, at the time of disclosure, (ii) subsequently becomes publicly available other than through any act or omission by the Recipient or (iii) otherwise subsequently becomes
known to the Recipient other than through a Person whom the Recipient knows to be acting in violation of his or its obligations to the Borrower, being hereinafter referred to as “Confidential Information”). The Recipient will
maintain the confidentiality of any Confidential Information in accordance with such procedures as the Recipient applies generally to information of that nature. It is understood, however, that the foregoing will not restrict the Recipient’s
ability to freely exchange such Confidential Information with its Affiliates or with current or prospective participants in or assignees of, or any current or prospective counterparty (or its advisors) to any swap, securitization or derivative
transaction relating to, the Recipient’s position herein, but the Recipient’s ability to so exchange Confidential Information shall be conditioned upon any such Affiliate’s or prospective participant’s or assignee’s or
counterparty’s entering into an understanding as to confidentiality similar to this provision. It is further understood that the foregoing will not prohibit the disclosure of any or all Confidential Information if and to the extent that such
disclosure may be required (i) by a regulatory agency or otherwise in connection with an examination of the Recipient’s records by appropriate authorities, (ii) pursuant to court order, subpoena or other legal process or in connection
with any pending or threatened litigation, (iii) otherwise as required by law, or (iv) in order to protect its interests or its rights or remedies hereunder or under the other Loan Documents; in the event of any required disclosure under
clause (ii) or (iii) above, the Recipient agrees to use reasonable efforts to inform the Borrower as promptly as practicable to the extent legally permitted to do so. 
 Section 8.9    WAIVER OF JURY TRIAL. THE AGENT, THE LC ISSUING BANK, THE LENDERS AND THE BORROWER HEREBY
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF
CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN), OR ACTIONS OF THE AGENT, THE LC ISSUING BANK, SUCH LENDERS OR THE BORROWER. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE AGENT, THE LC ISSUING BANK AND THE LENDERS ENTERING INTO
THIS AGREEMENT. 
 Section 8.10    Governing Law. This Agreement and the other Loan Documents shall be
governed by, and construed in accordance with, the laws of the State of New York; provided that each Letter of Credit shall be governed by, and construed in accordance with, the laws or rules designated in such Letter of Credit or application
therefor or, if no such laws or rules are designated, the International Standby Practices of the International Chamber of Commerce, as in effect from time to time (the “ISP”), and, as to matters not governed by the ISP, the
laws of the State of New York. The Borrower, each Lender, the LC Issuing Bank and the Agent (i) irrevocably submits to the non-exclusive jurisdiction of any New York State court or Federal court sitting in New York City in any action arising
out of any Loan Document, (ii) agrees that all claims in such action may be decided in such court, (iii) waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum and (iv) consents to the service of
process by mail, provided that a copy shall be promptly sent by overnight courier to Foley & 

  

 67 

 
Lardner LLP, U.S. Bank Center, 777 East Wisconsin Avenue, Milwaukee, Wisconsin 53202-5367, Attention: Emory Ireland, Esq. A final judgment in any such action
shall be conclusive and may be enforced in other jurisdictions. Nothing herein shall affect the right of any party to serve legal process in any manner permitted by law or affect its right to bring any action in any other court. 
 Section 8.11    Relation of the Parties; No Beneficiary. No term, provision or requirement, whether express or
implied, of any Loan Document, or actions taken or to be taken by any party thereunder, shall be construed to create a partnership, association, or joint venture between such parties or any of them. No term or provision of the Loan Documents shall
be construed to confer a benefit upon, or grant a right or privilege to, any Person other than the parties thereto. 
 Section 8.12    Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be
deemed to be an original and all of which taken together shall constitute one and the same agreement. 
 Section 8.13    Severability. To the extent any provision of this Agreement is prohibited by or invalid under the applicable law of any jurisdiction, such provision shall be ineffective only to the
extent of such prohibition or invalidity and only in such jurisdiction, without prohibiting or invalidating such provision in any other jurisdiction or the remaining provisions of this Agreement in any jurisdiction. 
 Section 8.14    Disclosure of Information. The Borrower agrees and consents to the Agent’s and the Joint
Arrangers’ disclosure of information relating to this transaction to Gold Sheets and other similar bank trade publications. Such information will consist of deal terms and other information customarily found in such publications.

 Section 8.15    USA Patriot Act Notice. Each Lender that is subject to the PATRIOT Act and the
Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the PATRIOT Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes
the name and address of the Borrower and other information that will allow such Lender or the Agent, as applicable, to identify the Borrower in accordance with the PATRIOT Act. 
 Section 8.16    Entire Agreement. This Agreement, together with any Note, the Fee Letters and any other
agreements, instruments and other documents required to be executed and delivered in connection herewith, represents the entire agreement of the parties hereto and supersedes all prior agreements and understandings of the parties with respect to the
subject matter covered hereby.

 FORM OF OPINION OF 
 FOLEY & LARDNER LLP 
 [Date of Amendment Effective Date] 
 To each of the Banks
parties to the 
 Credit Agreement referred to below, 
 and to Wachovia Bank, National Association, 
 as Administrative Agent, Swingline Lender and LC Issuing Bank

 Re: Alliant Energy Corporation 
 Ladies and Gentlemen: 
 This opinion is furnished to you pursuant to Section 3.1(a)(viii)(A) of the Second Amended and
Restated Five Year Credit Agreement, dated as of November 7, 2006 (the “Credit Agreement”), among Alliant Energy Corporation (the “Borrower”), the Banks parties thereto and Wachovia Bank, National
Association, as Administrative Agent, Swingline Lender and LC Issuing Bank. Terms defined in the Credit Agreement and not otherwise defined herein are used herein as therein defined. 
 We have acted as counsel for the Borrower in connection with the preparation, execution and delivery of, and the closing on this date (the
“Closing”) under, the Credit Agreement and the other Loan Documents. 
 In that capacity we have examined:

 (i) the Credit Agreement; 
 (ii) the Notes delivered in connection with the Closing, if any (the “Notes”); 
 (iii) the Fee Letters; 
 (iv) the Articles of Incorporation of the Borrower and all
amendments thereto (the “Borrower Charter”); and 
 (v) the by-laws of the Borrower and all amendments
thereto (the “Borrower By-laws”). 
 In addition, we have examined the originals, or copies certified to our
satisfaction, of such other corporate records of the Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments and other documents, as we have deemed necessary as a basis for the opinions expressed
below. As to questions of fact material to such opinions, we have, when relevant facts were not independently established by us, relied upon certificates of the Borrower or its officers, including the officer’s certificate annexed hereto as
Exhibit A (the “Officer’s Certificate”), or of public officials. 

 We have assumed (i) the due execution and delivery, pursuant to due authorization, of the Credit
Agreement by all parties to the Credit Agreement (other than the Borrower), (ii) the authenticity of all such documents submitted to us as originals, (iii) the genuineness of all signatures (other than those of the Borrower), (iv) the
conformity to the originals of all such documents submitted to us as copies and (v) the enforceability of all documents against parties thereto other than the Borrower. 
 Our opinions expressed herein are limited to the laws of the State of New York, the laws of the State of Wisconsin and the Federal laws of the United
States of America in effect on the date hereof as they presently apply and we express no opinion as to the laws of any other jurisdiction. We authorize Robinson, Bradshaw & Hinson, P.A., special counsel to the Agent, to rely on this
opinion. 
 Based upon the foregoing, but subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion
that: 
 1. Based solely upon a certificate issued by the Wisconsin Department of Financial Institutions, the Borrower is a validly existing
corporation, has filed its most recent annual report required by the Wisconsin Statutes and has not filed Articles of Dissolution as of the date of such certificate. 
 2. The execution, delivery and performance by the Borrower of the Credit Agreement, the Notes and the Fee Letters are within the Borrower’s corporate powers, have been duly authorized by all necessary corporate
action, and do not contravene (a) the Borrower Charter or the Borrower By-laws, or (b) any law, rule or regulation, or (c) any order or judgment of which we have knowledge applicable to the Borrower. The Credit Agreement, the Notes
and the Fee Letters have been duly executed and delivered on behalf of the Borrower. It is understood that the Borrower is required to obtain the Commitment Increase Approvals before any Commitment Increase. 
 3. No Governmental Approval is required in connection with the execution, delivery or performance by the Borrower of any Loan Document, or the
enforcement thereof by the Agent and the Lenders. 
 4. The Credit Agreement, the Notes and the Fee Letters are the legal, valid and binding
obligations of the Borrower, enforceable against the Borrower in accordance with their respective terms. 
 5. The Borrower is not an
“investment company” as defined in the Investment Company Act of 1940, as amended. 
 Wherever we indicate that our opinion with
respect to the existence or absence of facts is “to our knowledge” or the like, our opinion is, with your permission, based solely on the Officer’s Certificate and the current conscious awareness of facts or other information of the
attorneys currently with our firm who have represented the Borrower or any Subsidiary in connection with the transactions contemplated by the Credit Agreement, 

 Our opinion set forth in paragraph 4 above is limited by: 
  

	 	(a)	Applicable bankruptcy, receivership, reorganization, insolvency, moratorium, fraudulent conveyance or transfer, and other laws and judicially developed doctrines relating to or
affecting creditors’ rights and remedies generally; 

  

	 	(b)	General principles of equity, regardless of whether such enforcement is considered in a proceeding in equity or at law, and limitations on the availability of specific performance,
injunctive relief and other equitable remedies; 

  

	 	(c)	The possibility that certain rights, remedies, waivers, and other provisions of the Loan Documents may not be enforceable; nevertheless, such unenforceability will not render any of
the Loan Documents invalid as a whole or preclude (i) judicial enforcement of the obligation of Borrower to repay the principal, together with interest thereon (to the extent not deemed a penalty) as provided in the Credit Agreement and/or the
Notes; or (ii) acceleration of the obligation of Borrower to repay such principal, together with such interest, upon a material default in a material provision of the Loan Documents; and 

  

	 	(d)	The requirement and the enforcing party act in a commercially reasonable manner and in good faith in exercising its rights under the Loan Documents. 

 These opinions are given as of the date hereof, they are intended to apply only to those facts and circumstances that exist as of the date hereof, and we
assume no obligation or responsibility to update or supplement these opinions to reflect any facts or circumstances that may hereafter come to our attention or any changes in laws that may hereafter occur, or to inform the addressee of any change in
circumstances occurring after the date hereof that would alter the opinions rendered herein. 
 This opinion is limited to the matters set
forth herein, and no opinion may be inferred or implied beyond the matters expressly contained herein. Except as expressly set forth herein, this opinion, is being provided solely for the purpose of complying with the requirements of the Agent and
the Lenders in connection with the Credit Agreement, and is being rendered solely for the benefit of the addressees hereof, their participants, assignees and transferees. This opinion may not be used or relied upon for any other purpose, relied upon
by any other party, or filed with or disclosed to any governmental authority other than a court in connection with the enforcement or protection of the rights or remedies of the Agent and/or the Lenders under the Credit Agreement or to a banking
examiner or regulator in connection with an examination of the Agent and/or the Lenders by such governmental authority, without our prior written consent. 
 Very truly yours,

 FORM OF OPINION OF GENERAL COUNSEL OF THE 
 BORROWER 
 [Date of Amendment Effective Date] 
 To each of the Banks
parties to the 
 Credit Agreement referred to below, and to 
 Wachovia Bank, National Association, as Agent 
 Re: Alliant Energy Corporation 
 Ladies and Gentlemen: 
 This opinion is furnished to you
pursuant to Section 3.1(a)(viii)(B) of the Second Amended and Restated Five Year Credit Agreement, dated as of November 7, 2006 (the “Credit Agreement”), among Alliant Energy Corporation (the
“Borrower”), the Banks parties thereto and Wachovia Bank, National Association, as Agent, Swingline Lender and as LC Issuing Bank. Terms defined in the Credit Agreement and not otherwise defined herein are used herein as
therein defined. 
 I am the Executive Vice President and General Counsel of the Borrower and have acted as such in connection with the
preparation, execution and delivery of, and the closing on this date of, the Credit Agreement and the other Loan Documents. 
 In that
capacity I have examined, or have arranged for the examination by an attorney or attorneys under my general supervision of: 
 (i) the Credit Agreement; 
 (ii) the Notes delivered in connection with the closing of the Credit Agreement;

 (iii) the Fee Letters; 
 (iv) the Articles of Incorporation of the Borrower and all amendments thereto (the “Borrower Charter”); and 
 (v) the by-laws of the Borrower and all amendments thereto (the “Borrower By-laws”). 
 In addition, I, or an attorney or attorneys under my general supervision, have examined the originals, or copies certified to my or their satisfaction,
of such other corporate records of the Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments and other documents, as I or such attorneys have deemed necessary as a basis for the opinions expressed
below. As to questions of fact material to such opinions, I or such attorneys 

 
have, when relevant facts were not independently established by me or by them, relied upon certificates of the Borrower or its officers or of public
officials. 
 I have assumed (i) the due execution and delivery, pursuant to due authorization, of the Credit Agreement by all parties
to such document (other than the Borrower), (ii) the authenticity of all such documents submitted to me as originals, (iii) the genuineness of all signatures (other than those of the Borrower) and (iv) the conformity to the originals
of all such documents submitted to me as copies. 
 I, or an attorney or attorneys under my general supervision, have made such examination
of law as in my or their judgment is necessary or appropriate for purposes of this opinion. I and such attorneys do not, however, purport to be qualified to pass upon, and express no opinion as to, the laws of any jurisdiction other than the laws of
the State of Wisconsin. 
 Based upon and subject to the foregoing, I am of the opinion that: 
 1. The Borrower is a corporation duly organized, validly existing and in good standing under the laws of the State of Wisconsin and is duly qualified to
do business in, and is in good standing in, all other jurisdictions where the nature of its business or the nature of the property owned or leased by it makes such qualification necessary, except where the failure to so qualify would not have a
material adverse affect on the business, financial condition, results of operations or prospects of the Borrower and its Subsidiaries, taken as a whole. 
 2. The execution, delivery and performance by the Borrower of the Credit Agreement, the Notes and the Fee Letters are within the Borrower’s corporate powers, have been duly authorized by all necessary corporate
action, and do not contravene (a) the Borrower Charter or the Borrower By-laws; (b) any law, rule, regulation, order or judgment applicable to the Borrower, (c) any contractual restriction arising under any agreement or instrument
evidencing indebtedness described in Schedule III of the Credit Agreement; or (d) to my knowledge, any other legal or contractual restriction binding on, or affecting the Borrower or its properties; and such execution, delivery and performance
do not result in or require the creation or imposition of any Lien upon or with respect to any of its properties under any agreement or instrument evidencing indebtedness described in Schedule III of the Credit Agreement or, to my knowledge, under
any other agreement or instrument. The Credit Agreement, the Notes and the Fee Letters have been duly executed and delivered on behalf of the Borrower. 
 3. No Governmental Approval is required in connection with the execution, delivery or performance by the Borrower of any Loan Document, other than
            , which release[s] are final and in full force and effect and not subject to appeal, rehearing, review or reconsideration. 
 4. There is no pending or, to my knowledge, threatened action or proceeding affecting the Borrower or its properties before any court, governmental
agency or arbitrator, that could reasonably be expected, if adversely determined, to materially and adversely affect the business; financial condition, operations, results of operations or prospects of the Borrower, or affect the legality, validity
or enforceability of the Credit Agreement or any other Loan Document. 

 I authorize Foley & Lardner LLP, special counsel to the Borrower, to rely on this opinion
respecting matters covered by or relating to the laws of the State of Wisconsin. 
 Very truly yours, 

 EXHIBIT 8.7 
 FORM OF LENDER ASSIGNMENT 
 Dated
                    ,              
 Reference is made to the Second Amended and Restated Five Year Credit Agreement, dated as of November 7, 2006 (as amended, modified or supplemented
from time to time, the “Credit Agreement”, the terms defined therein being used herein as therein defined), among Alliant Energy Corporation, a Wisconsin corporation (the “Borrower”), the
Lenders named therein and Wachovia Bank, National Association, as Agent, Swingline Lender and LC Issuing Bank. Pursuant to the Credit Agreement, (the “Assignor”) has committed to make Advances (the
“Advances”) to the Borrower, which Advances are evidenced by one or more Notes (the “Notes”) issued by the Borrower to the Assignor. 
 The Assignor and                      (the
“Assignee”) agree as follows: 
 1. The Assignor hereby sells and assigns to the Assignee, and the Assignee hereby
purchases and assumes from the Assignor, that interest in and to all of the Assignor’s rights and obligations under the Credit Agreement as of the Effective Date (as defined below) which represents the percentage interest specified on Schedule
1 of all outstanding rights and obligations under the Credit Agreement (the “Assigned Interest”), including, without limitation, such interest in the Assignor’s Commitment, the Advances owing to the Assignor, the
Assignor’s participations in Letters of Credit and any Swingline Advances, and the Note or Notes (if any) held by the Assignor. After giving effect to such sale and assignment, the Assignee’s Commitment, the amount of the Advances owing to
the Assignee, and the Assignee’s participations in Letters of Credit and any Swingline Advances will be as set forth in Section 2 of Schedule 1. The effective date of this sale and assignment shall be the date specified on Schedule 1
hereto (the “Effective Date”). 
 2. On the Effective Date, the Assignee will pay to the Assignor, in same day funds,
at such address and account as the Assignor shall advise the Assignee, $            , and the sale and assignment contemplated hereby shall thereupon become effective. From and after
the Effective Date, the Assignor agrees that the Assignee shall be entitled to all rights, powers and privileges of the Assignor under the Credit Agreement and the Note or Notes (if any) to the extent of the Assigned Interest, including without
limitation (1) the right to receive all payments in respect of the Assigned Interest for the period from and after the Effective Date, whether on account of principal, interest, fees, indemnities in respect of claims arising after the Effective
Date, increased costs, additional amounts or otherwise, (2) the right to vote and to instruct the Agent under the Credit Agreement according to its Percentage based on the Assigned Interest, (3) the right to set-off and to appropriate and
apply deposits of the Borrower as set forth in the Credit Agreement and (4) the right to receive notices, requests, demands and other communications. The Assignor agrees that it will promptly remit to the Assignee any amount received by it in
respect of the Assigned Interest (whether from the Borrower, the Agent or otherwise) in the same funds in which such amount is received by the Assignor. 

 3. The Assignor (i) represents and warrants that it is the legal and beneficial owner of the
interest being assigned by it hereunder and that such interest is free and clear of any adverse claim; (ii) makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in
or in connection with the Credit Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency or value of the Credit Agreement or any other instrument or document furnished pursuant thereto; (iii) makes no
representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or the performance or observance by the Borrower of any of its obligations under the Credit Agreement or any other instrument or
document furnished pursuant thereto; and (iv) attaches the Note or Notes (if any) referred to in paragraph 1 above and requests that the Agent exchange such Notes (if any) for new Notes payable to the order of the Assignee in an amount equal to
the Commitment assumed by the Assignee pursuant hereto or new Notes payable to the order of the Assignee in an amount equal to the Commitment assumed by the Assignee pursuant hereto and the Assignor in an amount equal to the Commitment retained by
the Assignor under the Credit Agreement, respectively, as specified on Schedule 1 hereto. Except as specified in this Section 3, the assignment of the Assigned Interest shall be without recourse to the Assignor. 
 4. The Assignee (i) confirms that it has received a copy of the Credit Agreement and such other documents and information as it
has deemed appropriate to make its own credit analysis and decision to enter into this Lender Assignment; (ii) agrees that it will, independently and without reliance upon the Agent, the Assignor or any other Lender and based on such documents
and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Credit Agreement; (iii) confirms that it is an Eligible Assignee; (iv) appoints and authorizes the
Agent to take such action as agent on its behalf and to exercise such powers under the Credit Agreement as are delegated to the Agent by the terms thereof, together with such powers as are reasonably incidental thereto; (v) agrees that it will
perform in accordance with their terms all of the obligations which by the terms of the Credit Agreement are required to be performed by it as a Lender; [and] (vi) specifies as its Eurodollar Lending Office the office set forth beneath its name
on the signature pages hereof [and (vii) attaches the forms prescribed by the Internal Revenue Service of the United States certifying as to the Assignee’s status for purposes of determining exemption from United States withholding taxes
with respect to all payments to be made to the Assignee under the Credit Agreement and the Notes or such other documents as are necessary to indicate that all such payments are subject to such rates at a rate reduced by an applicable tax treaty].
1 
 5. Following the
execution of this Lender Assignment by the Assignor and the Assignee, it will be delivered to the Agent for acceptance and recording by the Agent. Upon such acceptance and recording by the Agent, as of the Effective Date, (i) the Assignee shall
be a party to the Credit Agreement and, to the extent provided in this Lender Assignment, have the rights and obligations of a Lender thereunder and under the other Loan Documents and (ii) the Assignor shall, to the extent provided in this
Lender Assignment, relinquish its rights and be released from its obligations under the Credit Agreement and the other Loan Documents. 
  

	1
	If the Assignee is organized under the laws of a jurisdiction outside the United States. 

 6. Upon such acceptance and recording by the Agent, from and after the Effective Date, the Agent shall
make all payments under the Credit Agreement and the Notes in respect of the interest assigned hereby (including, without limitation, all payments of principal, interest and commitment fees with respect thereto) to the Assignee. The Assignor and
Assignee shall make all appropriate adjustments in payments under the Credit Agreement and the Notes for periods prior to the Effective Date directly between themselves. 
 7. This Lender Assignment may be executed in any number of counterparts and by different parties in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken
together shall constitute but one and the same instrument. 
 8. This Lender Assignment shall be governed by, and construed in accordance
with, the laws of the State of New York. 
 IN WITNESS WHEREOF, the parties hereto have caused this Lender Assignment to be executed by their
respective officers thereunto duly authorized, as of the date first above written, such execution being made on Schedule 1 hereto.

to the Borrower (each, a “Term Loan” and collectively, the “Term Loans”) (i) on the Early Payment Date in accordance with Section 3.2 and (ii) on the Final Payment Date in accordance
with Section 3.3, in each case in an aggregate principal amount that will not result in (a) such Lender’s Credit Exposure exceeding such Lender’s Commitment or (b) the total Credit Exposures exceeding the Aggregate
Commitment. Once repaid or prepaid, Term Loans may not be reborrowed. 
 Section 2.2 Loans and Borrowings. 
 (a) Each Term Loan shall be made as part of a Borrowing on the Early Payment Date or the Final Payment Date, as applicable, and prior to the Commitment
Termination Date, with each such Borrowing consisting of Term Loans made by the Lenders ratably in accordance with their respective Commitments. The Term Loans shall, at the option of the Borrower as the Borrower may request in accordance herewith
and subject to the terms and conditions of this Agreement, be made as Borrowings of either Base Rate Advances or Eurodollar Rate Advances (each, a “Type” of Advance). Each Lender at its option may make any Eurodollar Rate
Advance by causing any Domestic Lending Office or Foreign Lending Office to make such Advance; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Term Loan in accordance with the terms of
this Agreement or result in any obligations of the Borrower to pay additional amounts under Section 2.13 or 2.17. Borrowings of more than one Type may be outstanding at the same time; provided that there shall not be
more than a total of three (3) Borrowings of Eurodollar Rate Advances outstanding at the same time. 
 (b) To request a Borrowing, the
Borrower shall notify the Agent of such request by telephone, facsimile or electronic mail (i) in the case of a Borrowing of Eurodollar Rate Advances, not later than 11:00 a.m., New York City time, three Business Days before the date of the
proposed Borrowing or (ii) in the case of a Borrowing of Base Rate Advances, not later than 11:00 a.m., New York City time, on the date of the proposed Borrowing. Such notice of a Borrowing (a “Notice of Borrowing”)
shall be in the form of Exhibit 2.2(b) hereto, delivered by hand, facsimile or electronic mail, and shall be executed by a Senior Financial Officer of the Borrower. The Notice of Borrowing shall specify the information contained in
clauses (i) through (v) below, in each case, in compliance with this Section 2.2: 
 (i) the aggregate amount of
the requested Borrowing; 
 (ii) the date of such Borrowing, which shall be the Early Payment Date or the Final Payment Date (and which in
any event shall also be a Business Day); 
 (iii) whether such Borrowing is to be of Base Rate Advances or Eurodollar Rate Advances;

  

 16 

 (iv) in the case of a Borrowing of Eurodollar Rate Advances, 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 account or accounts to which funds are to be disbursed. 
 (c) Each Lender shall, before (x) 12:00 noon on the
date of such Borrowing, in the case of a Borrowing comprised of Eurodollar Rate Advances, and (y) 1:00 p.m. on the date of such Borrowing, in the case of a Borrowing comprised of Base Rate Advances, make available for the account of its Applicable
Lending Office to the Agent at its address referred to in Section 8.2, in same day funds, such Lender’s ratable portion of such Borrowing. After the Agent’s receipt of such funds and upon fulfillment of the applicable
conditions set forth in Article III, the Agent will promptly make such funds available to the Borrower by means of a credit or wire transfer to the account specified in writing by the Borrower. 
 (d) The Notice of Borrowing shall be irrevocable and binding on the Borrower. If the Notice of Borrowing specifies that the Borrowing is to be comprised
of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the
applicable conditions set forth in Article III, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Eurodollar
Rate Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date. 
 (e) Upon the earlier of (1) the making of the Term Loans on the Final Payment Date and (2) 5:00 p.m. New York City time on the Final Payment Date (such earlier date, the “Commitment Termination Date”), all
Commitments (regardless of utilization) shall immediately, automatically and irrevocably terminate. 
 Section 2.3 Funding
Reliance. 
 (a) Unless the Agent shall have received notice from a Lender prior to the time of the Borrowing that such Lender will
not make available to the Agent such Lender’s Advance as part of such Borrowing, the Agent may assume that such Lender has made such Advance available to the Agent on the time of such Borrowing in accordance with Section
2.2 and the Agent may, in reliance upon such assumption, make available to the Borrower on such time a corresponding amount. If and to the extent that such Lender shall not have so made such Advance available to the Agent, such Lender and
the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the time such amount is made available to the Borrower until the time such amount is repaid to the
Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall repay to the Agent such
corresponding amount, such amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement. 
  

 17 

 (b) The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not
relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date
of any Borrowing. 
 Section 2.4 [Intentionally Omitted]. 
 Section 2.5 Fees. 
 (a) The
Borrower agrees to pay to the Agent for the account of each Lender the Facility Fee, from the date hereof, in the case of each Bank, and from the effective date specified in the Lender Assignment pursuant to which it became a Lender, in the case of
each other Lender, until the earlier of the Commitment Termination Date and the Maturity Date, payable monthly in arrears on the last day of each calendar month during the term of such Lender’s Commitment, commencing September 30, 2009,
and ending on the earlier of the Commitment Termination Date and the Maturity Date. 
 (b) Anything herein to the contrary notwithstanding,
during such period as a Lender is a Defaulting Lender, such Defaulting Lender will not be entitled to any fees accruing during such period pursuant to Section 2.5(a) above (without prejudice to the rights of the Lenders other than
Defaulting Lenders in respect of such fees). 
 Section 2.6 [Intentionally Omitted]. 
 Section 2.7 Repayment of Advances. Except to the extent due or paid sooner pursuant to the provisions of this Agreement, the
aggregate outstanding principal amount of the Term Loans, if any, shall be due and payable in full on the Maturity Date. 
 Section 2.8 Interest on Advances. The Borrower shall pay interest on the unpaid principal amount of each Advance owing to each Lender from the date of such Advance until such principal amount shall be paid in
full, at the Applicable Rate for such Advance (except as otherwise provided in this Section 2.8), payable as follows: 
 (a) If such Advance is a Base Rate Advance, interest thereon shall be payable quarterly in arrears on the last day of each March, June, September and December, on the date of any Conversion of such Base Rate Advance and on the date such
Base Rate Advance shall become due and payable or shall otherwise be paid in full; provided that at any time an Event of Default shall have occurred and be continuing, each Base Rate Advance shall bear interest payable on demand, at a rate
per annum equal at all times to the Default Rate. 
 (b) If such Advance is a Eurodollar Rate Advance, interest thereon shall be payable on
the last day of such Interest Period; provided that at any time an Event of Default shall have occurred and be continuing, each Eurodollar Rate Advance shall bear interest payable on demand, at a rate per annum equal at all times to
the Default Rate. 
  

 18 

 (c) In respect of any Advance, interest thereon shall be payable at the Applicable Rate at maturity
(whether pursuant to acceleration or otherwise) and, after maturity, on demand. 
 (d) Nothing contained in this Agreement or in any other
Loan Document shall be deemed to establish or require the payment of interest to any Lender at a rate in excess of the maximum rate permitted by applicable law. If the amount of interest payable for the account of any Lender on any interest payment
date would exceed the maximum amount permitted by applicable law to be charged by such Lender, the amount of interest payable for its account on such interest payment date shall be automatically reduced to such maximum permissible amount. In the
event of any such reduction affecting any Lender, if from time to time thereafter the amount of interest payable for the account of such Lender on any interest payment date would be less than the maximum amount permitted by applicable law to be
charged by such Lender, then the amount of interest payable for its account on such subsequent interest payment date shall be automatically increased to such maximum permissible amount, provided that at no time shall the aggregate amount by
which interest paid for the account of any Lender has been increased pursuant to this sentence exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant to the previous sentence. 
 Section 2.9 Additional Interest on Eurodollar Rate Advances. The Borrower shall pay to Agent for the account of each Lender
any costs actually incurred by such Lender with respect to Eurodollar Rate Advances that are attributable to such Lender’s compliance with regulations of the Board of Governors of the Federal Reserve System requiring the maintenance of reserves
with respect to liabilities or assets consisting of or including Eurocurrency Liabilities. Such costs shall be paid to the Agent for the account of such Lender in the form of additional interest on the unpaid principal amount of each Eurodollar Rate
Advance of such Lender, from the date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for
such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such
Advance. Such additional interest shall be determined by such Lender and notified to the Borrower through the Agent. A certificate as to the amount of such additional interest, submitted to the Borrower and the Agent by such Lender, shall be
conclusive and binding for all purposes, absent manifest error, provided that the determination thereof shall have been made by such Lender in good faith. 
 Section 2.10 Interest Rate Determination.

Rate Advance on or prior to 12:00 noon on the third Business Day prior to the last day of the Interest Period applicable thereto, the Agent will forthwith so notify the Borrower and the Lenders and such Advance will automatically, on the last day of
the then existing Interest Period therefor, Convert into a Base Rate Advance. 
 (f) On the date on which the aggregate unpaid principal
amount of Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than the product of (i) $1,000,000 and (ii) the number of Lenders on such date, such Advances shall, if they are Advances of a
Type other than Base Rate Advances, automatically Convert into Base Rate Advances, and on and after such date the right of the Borrower to Convert such Advances into Advances of a Type other than Base Rate Advances shall terminate; provided,
however, that if and so long as each such Advance shall be of the same Type and have the same Interest Period as Advances comprising another Borrowing or other Borrowings, and the aggregate unpaid principal amount of all such Advances shall
equal or exceed the product of (i) $1,000,000 and (ii) the number of Lenders on such date, the Borrower shall have the right to continue all such Advances as, or to Convert all such Advances into, Advances of such Type having such Interest
Period. 
 (g) Upon the occurrence and during the continuance of any Event of Default, each outstanding Eurodollar Rate Advance shall
automatically Convert into a Base Rate Advance at the end of the Interest Period then in effect for such Eurodollar Rate Advance. 
 Section 2.11 Voluntary Conversion of Advances. Subject to the conditions set forth below, the Borrower may, on any Business Day, by delivering a notice of Conversion (a
“Notice of Conversion”) to the Agent not later than 12:00 noon (i) on the third Business Day prior to the date of the proposed Conversion, in the case of a Conversion to or in respect of Eurodollar Rate Advances and (ii) on
the date of the proposed Conversion, in the case of a Conversion to or in respect of Base Rate Advances, and subject to the provisions of Section 2.10 and Section 2.15, Convert all Advances of one Type
comprising the same Borrowing into Advances of another Type; provided, however, that, in the case of any Conversion of any Eurodollar Rate Advances into Base Rate Advances on a day other than the last day of an Interest Period for such
Eurodollar Rate Advances, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.4(b). Each such Notice of Conversion shall be in substantially the form of Exhibit
2.11 and shall, within the restrictions specified above, specify (A) the date of such Conversion, (B) the Advances to be Converted, (C) if such Conversion is into Eurodollar Rate Advances, the duration of the Interest Period
for each such Advance, and (D) the aggregate amount of Advances proposed to be Converted. Notwithstanding the foregoing, the Borrower may not Convert Base Rate Advances into Eurodollar Rate Advances and may not select a new Interest Period for
Eurodollar Rate Advances at any time an Event of Default has occurred and is continuing.

Prepayments of Advances. 
  

 20 

 (a) The Borrower may, upon at least three Business Days’ notice to the Agent stating the proposed
date and aggregate principal amount of the prepayment, and if such notice is given, the Borrower shall, prepay for the ratable account of the Lenders the outstanding principal amounts of the Advances comprising part of the same Borrowing in whole or
ratably in part, without premium or penalty, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, that each partial prepayment shall be in an aggregate principal amount not
less than $1,000,000 (or, if lower, the principal amount outstanding hereunder on the date of such prepayment) or an integral multiple of $1,000,000 in excess thereof. In the case of any such prepayment of a Eurodollar Rate Advance, the Borrower
shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.4(b). Except as provided in this Section 2.12(a), the Borrower shall have no right to prepay any principal amount of any Advances.

 (b) In the event that at any time, or from time to time, on or after the Effective Date and prior to the Commitment Termination Date, the
Borrower or any of its Subsidiaries shall receive any Net Cash Proceeds of any Reduction Event, then the Commitments, if any, shall automatically be reduced, to the extent thereof (but not below zero), by an aggregate amount equal to such Net Cash
Proceeds (with each Lender’s Commitment being reduced ratably according to its respective Percentage). The reductions in the Commitments required by this subsection (b) shall be effective on the date of receipt by the Borrower or any of
its Subsidiaries of such Net Cash Proceeds. 
 (c) In the event that at any time, or from time to time, on or after the Funding Date, the
Borrower or any of its Subsidiaries shall receive any Net Cash Proceeds of any Reduction Event and the Commitments shall have been reduced to zero (whether through the operation of clause (b) above or because the Commitment Termination Date
shall have occurred), the Term Loans shall be prepaid to the extent necessary for the ratable account of the Lenders in an aggregate principal amount equal to such Net Cash Proceeds less any amount applied to reduce Commitments in accordance with
clause (b) above. Each such prepayment shall be made together with accrued interest on the amount prepaid and shall be made not later than the third Business Day following the date of such receipt. 
 (d) The Borrower shall notify the Agent not later than the date of receipt by the Borrower or any of its Subsidiaries of the Net Cash Proceeds of a
Reduction Event, specifying the date and amount thereof. The Agent shall promptly notify each Lender of the contents of each such notice received by it. 
 Section 2.13 Increased Costs. 
 (a) If, due to either (i) the introduction of or any
change (other than any change by way of imposition or increase of reserve requirements, in the case of Eurodollar Rate Advances, included in the Eurodollar Rate Reserve Percentage) in or to the interpretation of any law or regulation or
(ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding, or
maintaining Eurodollar Rate Advances, then the Borrower shall from time to time, upon demand by such Lender, pay to the Agent for the account of such Lender additional amounts sufficient to compensate such 
  

 21 

 Lender for such increased cost. A certificate as to the amount of such increased cost, submitted to the
Borrower and the Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error, provided that the determination thereof shall have been made by such Lender in good faith. 
 (b) If any Lender determines that compliance with any law or regulation or any guideline or request from any central bank or other
governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital is
increased by or based upon the existence of such Lender’s commitment to lend hereunder, then, upon demand by such Lender, the Borrower shall immediately pay to the Agent for the account of such Lender, from time to time as specified by such
Lender, additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such
Lender’s Commitment or other obligations hereunder. A certificate as to such amounts submitted to the Borrower and the Agent by such Lender, describing in reasonable detail the manner in which such amounts have been calculated, shall be
conclusive and binding for all purposes, absent manifest error, provided that the determination and allocation thereof shall have been made by such Lender in good faith. 
 (c) Notwithstanding any provision of Section 2.13(a) or Section 2.13(b) to the contrary, no Lender
shall be entitled to demand compensation or be compensated thereunder to the extent that such compensation relates to any period of time more than 60 days prior to the date upon which such Lender first notified the Borrower of the occurrence of the
event entitling such Lender 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 Borrower). 
 Section 2.14 Illegality. Notwithstanding any other provision of this Agreement to the contrary, if any Lender
(the “Affected Lender”) shall notify the Agent and the Borrower that the introduction of or any change in or to the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental
authority asserts that it is unlawful, for the Affected Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, all Eurodollar Rate
Advances of the Affected Lender shall, on the fifth Business Day following such notice from the Affected Lender, automatically be Converted into a like number of Base Rate Advances, each in the amount of the corresponding Eurodollar Rate Advance of
the Affected Lender being so Converted (each such Advance, as so Converted, being an “Affected Lender Advance”), and the obligation of the Affected Lender to make, maintain, or Convert Advances into Eurodollar Rate Advances
shall thereupon be suspended until the Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, or the Affected Lender has been replaced pursuant to Section 8.7. For purposes
of any prepayment under this Agreement, each Affected Lender Advance shall be deemed to continue to be part of the same Borrowing as the Eurodollar Rate Advances to which it corresponded at the time of the Conversion of such Affected Lender Advance
pursuant to this Section 2.14. 
 Section 2.15 Payments and Computations. 
  

 22 

 (a) The Borrower shall make each payment hereunder not later than 1:00 p.m. on the day when
due in Dollars to the Agent at its address referred to in Section 8.2 in same day funds. The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or fees ratably
(other than amounts payable pursuant to Section 2.9, Section 2.17 or Section 8.4(b)) to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any
other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of a Lender Assignment and recording of the
information contained therein in the Register pursuant to Section 8.7, from and after the effective date specified in such Lender Assignment, the Agent shall make all payments hereunder in respect of the interest assigned thereby
to the Lender assignee thereunder, and the parties to such Lender Assignment shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. 
 (b) The Borrower hereby authorizes each Lender, if and to the extent payment owed to such Lender is not made when due hereunder, to charge
from time to time against any or all of the Borrower’s accounts with such Lender any amount so due. 
 (c) All computations
of interest based on clause (i) of the definition of “Alternate Base Rate” and of the Facility Fee shall be made by the Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of
interest based on the Eurodollar Rate and the Federal Funds Rate shall be made by the Agent, and all computations of interest pursuant to Section 2.10 shall be made by a Lender, on the basis of a year of 360 days, in each case for the
actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Agent (or, in the case of Section 2.10, by a Lender) of an
interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error, provided that such determination shall have been made by the Agent or such Lender, as the case may be, in good faith. 
 (d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided, however, that if such extension would cause payment of interest on or
principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the immediately preceding Business Day. 
 (e) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders hereunder that the Borrower will not make such payment in full, the Agent may
assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and
to the extent that the Borrower shall not have so made such payment in full to the Agent, each Lender shall repay to the Agent forthwith on demand such amount distributed to such Lender together with interest thereon, for each day from the date such
amount is distributed to such Lender until the date such Lender repays such amount to the Agent, at the Federal Funds Rate.

 Section 2.16 Noteless Agreement; Evidence of Indebtedness. 
 (a) 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 Advance made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. 
 (b) The Agent shall also maintain accounts in which it will record (i) the amount of each Advance made hereunder, the Type thereof and the Interest
Period (if any) with respect 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 Agent hereunder
from the Borrower and each Lender’s share thereof. 
 (c) The entries maintained in the accounts maintained pursuant to Section
2.16(a) and Section 2.16(b) shall be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts
or any error therein shall not in any manner affect the obligation of the Borrower to repay such obligations in accordance with their terms. 
 (d) The Advances made by each Lender shall, if requested by the applicable Lender (which request shall be made to the Agent), be evidenced by a Term Note, appropriately completed and executed by the Borrower and payable to the order of such
Lender. Each Term Note shall be entitled to all of the benefits of this Agreement and the other Loan Documents and shall be subject to the provisions hereof and thereof. 
 Section 2.17 Taxes. 
 (a) Any and all payments by the Borrower hereunder and under the other
Loan Documents shall be made, in accordance with Section 2.15, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, excluding, in the case of each Lender and the Agent, taxes imposed on its overall net income and franchise taxes imposed on it by any jurisdiction, unless such Lender or the Agent (as the case may be) would not have had such
taxes imposed on it by such jurisdiction but for such Lender’s or the Agent’s (as the case may be) having entered into this Agreement, having consummated the transactions contemplated hereby or having received payments by the Borrower
hereunder or under the other Loan Documents (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by law
to deduct any Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Lender or the Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 2.17) such Lender 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 Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. 
  

 24 

 (b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other
excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any other Loan Document or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or any other Loan
Document (hereinafter referred to as “Other Taxes”). 
 (c) The Borrower will indemnify each Lender and the Agent for
the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.17) paid by such Lender or the Agent (as the case may be) and
any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such
Lender or the Agent (as the case may be) makes written demand therefor. Nothing herein shall preclude the right of the Borrower to contest any such Taxes or Other Taxes so paid, and the Lenders in question or the Agent (as the case may be) will,
following notice from, and at the expense of, the Borrower, reasonably cooperate with the Borrower to preserve the Borrower’s rights to contest such Taxes or Other Taxes. 
 (d) Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at its address referred to in Section
8.2, the original or a certified copy of a receipt evidencing payment thereof. 
 (e) Each Lender agrees that, on or prior to the
date upon which it shall become a party hereto, and upon the reasonable request from time to time of the Borrower or the Agent, such Lender will deliver to the Borrower and the Agent either (i) a statement that it is organized under the laws of
a jurisdiction within the United States or (ii) duly completed copies of such form or forms as may from time to time be prescribed by the United States Internal Revenue Service indicating that such Lender is entitled to receive payments without
deduction or withholding of any United States federal income taxes, as permitted by the Internal Revenue Code of 1986, as amended from time to time. Each Lender that delivers to the Borrower and the Agent the form or forms referred to in the
preceding sentence further undertakes to deliver to the Borrower and the Agent further copies of such form or forms, or successor applicable form or forms, as the case may be, as and when any previous form filed by it hereunder shall expire or shall
become incomplete or inaccurate in any respect. Each Lender represents and warrants that each such form supplied by it to the Agent and the Borrower pursuant to this Section 2.17(e), and not superseded by another form supplied
by it, is or will be, as the case may be, complete and accurate. 
 (f) Any Lender claiming any additional amounts payable pursuant to this
Section 2.17 shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the
need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender. 
  

 25 

 (g) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements
and obligations of the Borrower contained in this Section 2.17 shall survive the payment in full of principal and interest hereunder. 
 Section 2.18 Sharing of Payments, Etc. All payments from or on behalf of the Borrower on account of any obligations shall be apportioned ratably among the Lenders based upon their respective share, if
any, of the obligations with respect to which such payment was received. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set off, or otherwise) on account of the Advances made by it (other
than pursuant to Section 2.9, Section 2.13, Section 2.17 or Section 8.4(b)) in excess of its ratable share of payments obtained by all the Lenders on account of the Advances, such Lender shall forthwith purchase from
the other Lenders such participations in the Advances made by them and such reimbursement obligations as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that
if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such
recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any
interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.18
may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such
participation. 
 Section 2.19 Termination of Defaulting Lender Commitment. 
 The Borrower may terminate the unused amount of the Commitment of a Defaulting Lender upon not less than 3 Business Days’ prior notice to the Agent (which will
promptly notify the Lenders thereof), and in such event the provisions of Section 2.18 will apply to all amounts thereafter paid by the Borrower for the account of such Defaulting Lender under this Agreement (whether on account of principal,
interest, fees, indemnity or other amounts), provided that such termination will not be deemed to be a waiver or release of any claim the Borrower, the Agent or any Lender may have against such Defaulting Lender. 
 Section 2.20 Replacement of Lenders. 
 The
Borrower may, at any time at its sole expense and effort, require any Lender (i) that does not approve a consent, waiver or amendment to any Loan Document requested by the Borrower or the Agent and that requires the approval of all Lenders
under Section 8.1 which is otherwise approved by the Majority Lenders, or (ii) that requests compensation under Section 2.13, or to which the Borrower is required to pay any additional amount (or for the account of
which the Borrower is required to pay any additional amount to any Governmental Authority) pursuant to Section 2.17, or (iii) that is a Defaulting Lender, in each case upon notice to such Lender and the Agent, to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 8.7), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an
assignee that shall 
  

 26 

 assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided
that: 
 (i) no Unmatured Default or Event of Default shall have occurred and be continuing at such time; 
 (ii) the Agent shall have received the assignment fee specified in Section 8.7(a) (which fee shall, notwithstanding
the terms of Section 8.7(a), be paid by the Borrower in respect of an assignment pursuant to this Section 2.20); 
 (iii) such Lender shall have received payment of an amount equal to the outstanding principal of its Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents
(including any amounts under Section 8.4(b)) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts); 
 (iv) such assignee, if it is not an existing Lender and/or Eligible Assignee, shall be reasonably satisfactory to the Agent; and

 (v) such assignment does not conflict with any applicable laws, rules, regulations and orders of any governmental authority
or otherwise require any Governmental Approvals. 
 A Lender shall not be required to make any assignment or delegation if, prior thereto, the circumstances
entitling the Borrower to require such assignment and delegation cease to apply.

reasonably expected to result in a liability to the Borrower and neither the Borrower nor any of its ERISA Affiliates has incurred nor reasonably expects to incur any withdrawal liability under ERISA to any Multiemployer Plan, in each case that

governmental authority in respect of the conduct of its business and the ownership and operation of its properties, except in each case to the extent that the failure to comply therewith, individually or in the aggregate, could not reasonably be
expected to constitute a Material Adverse Change. 
 ARTICLE V 
 COVENANTS OF THE BORROWER 
 Section 5.1 Affirmative Covenants. So
long as any amount in respect of this Agreement shall remain unpaid, or any Lender shall have any Commitment or Credit Exposure, the Borrower will, unless the Majority Lenders shall otherwise consent in writing: 
 (a) Payment of Taxes, Etc. Pay and discharge, and cause each of its Domestic Subsidiaries to pay and discharge, before the same shall become
delinquent, all taxes, assessments and governmental charges, royalties or levies imposed upon it or upon its property 

  

 33 

 except, in the case of taxes, to the extent the Borrower or such Domestic Subsidiary is contesting the same in good faith
and by appropriate proceedings and has set aside adequate reserves for the payment thereof in accordance with GAAP, unless the failure to do so would not constitute a Material Adverse Change. 
 (b) Maintenance of Insurance. Maintain, or cause to be maintained, insurance or other risk management programs covering the Borrower and each of
its Subsidiaries and their respective properties in effect at all times in such amounts and covering such risks and using such means as are usual and customary for companies of a similar size (based on the aggregate book value of the Borrower’s
assets, as determined on a consolidated basis in accordance with GAAP), engaged in similar businesses and owning similar properties, either with reputable insurance companies or, in whole or in part, by establishing reserves of one or more insurance
funds or other risk management mechanisms, either alone or with other corporations or associations, unless the failure to do so would not constitute a Material Adverse Change. 
 (c) Preservation of Existence, Etc. Preserve and maintain, and cause each of the Utilities to preserve and maintain, its corporate existence
(except in a transaction permitted by Section 5.2(c)), material rights (statutory and otherwise) and franchises; provided, however, that neither the Borrower nor any of the Utilities shall be required to preserve and maintain any
such right or franchise, unless the failure to do so would constitute a Material Adverse Change. 
 (d) Compliance with Laws, Etc.

 THE AGENT

 Section 7.1 Authorization and Action. Each of the Lenders hereby irrevocably appoints Citi to act on its behalf as the
Agent hereunder and under the other Loan Documents and authorizes the Agent to take such action as agent on its behalf and to exercise such powers under this Agreement or the other Loan Documents as are delegated to the Agent by the terms hereof or
thereof, together with such actions and powers as are reasonably incidental thereto. 
  

 43 

 The Agent’s duties hereunder and under the other Loan Documents are solely ministerial and administrative in nature
and the Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Agent shall not be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders (or such other number or percentage of the Lenders as shall be
expressly provided for herein or in the other Loan Documents), and such instructions shall be binding upon all Lenders and all holders of Term Notes (if any); provided, however, that the Agent shall not be required to take any action
which, in its opinion or the opinion of its counsel, may expose the Agent to liability or which is contrary to this Agreement, any other Loan Document or applicable law. The Agent agrees to give to each Lender prompt notice of each notice given to
it by the Borrower pursuant to the terms of this Agreement. The Agent shall be deemed to have exercised reasonable care in the administration and enforcement of this Agreement and the other Loan Documents if it undertakes such administration and
enforcement in a manner substantially equal to that which Wachovia accords credit facilities similar to the credit facility hereunder for which it is the sole lender. The provisions of this Article are solely for the benefit of the Agent and the
Lenders except as otherwise expressly provided herein, and the Borrower shall have no rights as a third party beneficiary of any of such provisions.

them (i) with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in this
Agreement) or (ii) in the absence of its or their own gross negligence or willful misconduct. The Agent shall be deemed not to have knowledge of any Unmatured Default or the event or events that give or may give rise to any Unmatured Default unless
and until the Borrower or any Lender shall have given notice to the Agent describing such Unmatured Default and such event or events. Without limitation of the generality of the foregoing, the Agent and each member of the Agent’s Group: (i) may
treat the payee of any Term Note as the holder thereof until the Agent receives and accepts a Lender Assignment entered into by the Lender which is the payee of such Term Note, as assignor, and an Eligible Assignee, as assignee, as provided in
Section 8.7; (ii) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by

this Agreement or any other Loan Document, (2) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith or the adequacy, accuracy and/or completeness of the information
contained therein, (3) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Unmatured Default or Event of Default, (4) the validity, enforceability,
effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or the perfection or 
  

 44 

 priority of any lien or security interest created or purported to be created by the Loan Documents or (5) the
satisfaction of any condition set forth in Article III or elsewhere herein, other than (but subject to the foregoing clause (2)) to confirm receipt of items expressly required to be delivered to the Agent (and in
determining compliance with any condition hereunder to the making of an Advance that by its terms must be fulfilled to the satisfaction of a Lender, the Agent may presume that such condition is satisfactory to such Lender unless an officer of the
Agent responsible for the transactions contemplated hereby shall have received notice to the contrary from such Lender prior to the making of such Advance, and in the case of a Borrowing, such Lender shall not have made available to the Agent such
Lender’s ratable portion of such Borrowing), or (y) to inspect the property (including the books and records) of the Borrower; (v) shall not be responsible to any Lender for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto or thereto; (vi) may rely on, and shall incur no liability under or in respect of this Agreement or any
other Loan Document by relying or acting upon, (x) any notice, consent, certificate or other instrument or writing (which may be by telecopier, telegram, cable or telex, and including any electronic message, Internet or intranet website posting
or other distribution) believed by it to be genuine and signed, otherwise authenticated or sent by the proper party or parties, and (y) any statement made to it orally or by telephone and believed by it to have been made by the proper party or
parties; and (vii) shall not be required to carry out any “know your customer” or other checks in relation to any person on behalf of any Lender and each Lender confirms to the Agent that it is solely responsible for any such checks
it is required to carry out and that it may not rely on any statement in relation to such checks made by the Agent or any members of the Agent’s Group. 
 Section 7.3 Citi and Affiliates. With respect to the Advances made by it, the Person serving as Agent hereunder shall have the same rights and powers in its capacity as a Lender under this Agreement as
any other Lender and may exercise the same as though it were not the Agent; and the term “Bank” or “Banks” and “Lender” or “Lenders” shall, unless otherwise expressly indicated, include the Person serving as
Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or the trustee under indentures of, and generally engage in any kind of business with, the Borrower or
any Subsidiary or other Affiliate thereof and any Person who may do business with or own securities of the Borrower or any Subsidiary or other Affiliate thereof, all as if such Person were not the Agent and without any duty to account therefor to
the Lenders. 
 Each Lender understands that the Person serving as Agent, acting in its individual capacity, and its Affiliates
(collectively, the “Agent’s Group”) are engaged in a wide range of financial services and businesses (including investment management, financing, securities trading, corporate and investment banking and research) (such
services and businesses are collectively referred to in this Section 7.3 as “Activities”) and may engage in the Activities with or on behalf of the Borrower or its Affiliates. Furthermore, the Agent’s Group
may, in undertaking the Activities, engage in trading in financial products or undertake other investment businesses for its own account or on behalf of others (including the Borrower or its Affiliates and including holding, for its own account or
on behalf of others, equity, debt and similar positions in the Borrower or its Affiliates), including trading in or holding long, short or derivative positions in securities, loans or other financial products of the Borrower or its Affiliates. Each
Lender understands and agrees that in engaging in the Activities, the Agent’s Group may receive or 

  

 45 

 otherwise obtain information concerning the Borrower or its Affiliates (including information concerning the ability of
the Borrower to perform its obligations hereunder and under the other Loan Documents) which information may not be available to any of the Lenders that are not members of the Agent’s Group. None of the Agent nor any member of the Agent’s
Group shall have any duty to disclose to any Lender or use on behalf of the Lenders, and shall not be liable for the failure to so disclose or use, any information whatsoever about or derived from the Activities or otherwise (including any
information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of the Borrower or its Affiliates) or to account for any revenue or profits obtained in connection with the Activities, except
that the Agent shall deliver or otherwise make available to each Lender such documents as are expressly required by any Loan Document to be transmitted by the Agent to the Lenders. 
 Each Lender further understands that there may be situations where members of the Agent’s Group or their respective customers (including the
Borrower and its Affiliates) either now have or may in the future have interests or take actions that may conflict with the interests of any one or more of the Lenders (including the interests of the Lenders hereunder and under the other Loan
Documents). Each Lender agrees that no member of the Agent’s Group is or shall be required to restrict its activities as a result of the Person serving as Agent being a member of the Agent’s Group, and that each member of the Agent’s
Group may undertake any Activities without further consultation with or notification to any Lender. None of (i) this Agreement nor any other Loan Document, (ii) the receipt by the Agent’s Group of information (including Confidential
Information) concerning the Borrower or its Affiliates (including information concerning the ability of the Borrower to perform its obligations hereunder and under the other Loan Documents) nor (iii) any other matter shall give rise to any
fiduciary, equitable or contractual duties (including without limitation any duty of trust or confidence) owing by the Agent or any member of the Agent’s Group to any Lender including any such duty that would prevent or restrict the
Agent’s Group from acting on behalf of customers (including the Borrower or its Affiliates) or for its own account. 
 Section 7.4
Lender Credit Decision. Each Lender acknowledges and confirms to the Agent, each other Lender and each of their respective Related Parties that it (i) is solely responsible for making its own independent appraisal and investigation of
all risks arising under or in connection with this Agreement and the other Loan Documents, and (ii) has, independently and without reliance upon the Agent or any other Lender or any of their respective Related Parties and based on the financial
statements referred to in Section 4.1(f) and such other documents and information as it has deemed appropriate, made its own appraisal and investigation of all risks associated with, and made its own credit analysis and decision
to enter into, this Agreement. Each Lender acknowledges and confirms to the Agent, each other Lender and each of their respective Related Parties that it (i) possesses (individually or through its Related Parties) such knowledge and experience
in financial and business matters that it is capable, without reliance on the Agent, any other Lender or any of their respective Related Parties, of evaluating the merits and risks (including tax, legal, regulatory, credit, accounting and other
financial matters) of (x) entering into this Agreement, (y) making Advances and other extensions of credit hereunder and under the other Loan Documents and (z) in taking or not taking actions hereunder and thereunder, (ii) is
financially able to bear such risks and (iii) has determined that entering into this Agreement and making Advances and other extensions of credit hereunder and under the other Loan Documents is suitable and appropriate for it. Each 

 

 46 

 Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender 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. Each Lender represents and acknowledges that it has not relied, and is not
relying, on Margin Stock as collateral for the Advances or for any other extensions of credit hereunder. 
 Section 7.5
Indemnification. The Lenders agree to indemnify the Agent and any Related Party of the Agent participating in the transaction (to the extent not reimbursed by the Borrower), ratably according to the respective outstanding principal amounts
of the Advances, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or 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 action taken or omitted by the Agent under this Agreement, provided that no Lender shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Agent promptly upon
demand for its ratable share of any out of pocket expenses (including counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations,
legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Agent is not reimbursed for such expenses by the Borrower. 
 Section 7.6 Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower and may be
removed at any time with or without cause by the Majority Lenders, with any such resignation or removal to become effective only upon the appointment of a successor Agent pursuant to this Section 7.6. Upon any such resignation or
removal, the Majority Lenders shall have the right to appoint a successor Agent, which shall be a Lender or shall be another commercial bank or trust company (and reasonably acceptable to the Borrower so long as no Event of Default exists) organized
under the laws of the United States or of any State thereof. If no successor Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring Agent’s giving of notice of
resignation or the Majority Lenders’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a Lender or shall be another commercial bank or trust company organized under
the laws of the United States of any State thereof reasonably acceptable to the Borrower. In addition and without any obligation on the part of the retiring Agent to appoint, on behalf of the Lenders, a successor Agent, the retiring Agent may at any
time upon or after the end of such 30 day period notify the Borrower and the Lenders that no qualifying Person has accepted appointment as successor Agent and the effective date of such retiring Agent’s resignation which effective date shall be
no earlier than three business days after the date of such notice. Upon the resignation effective date established in such notice and regardless of whether a successor Agent has been appointed and accepted such appointment, the retiring Agent’s
resignation shall nonetheless become effective and (i) the retiring Agent shall be discharged from its duties and obligations as Agent hereunder and under the other Loan Documents and (ii) all payments, communications and determinations
provided to be made by, to or through the Agent shall instead be made by or to each Lender directly, until such time as the Majority Lenders appoint a successor Agent as 
  

 47 

 provided for above in this paragraph. Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement
or under the other Loan Documents (if not already discharged therefrom as provided above in this paragraph). After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of this Article VII 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 the retiring Agent was acting as Agent. 
 Section 7.7 Delegation of Duties. The Agent may perform any and all of its duties and exercise its rights and powers
hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Agent; provided, however, that the Agent shall remain responsible for the performance of its duties under this Agreement and the Loan
Documents to the extent required under this Article. The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The indemnification, reimbursement and
exculpatory provisions of this Article shall apply to any such sub-agent and to the Affiliates and the partners, directors, officers, employees, agents and advisors of the Agent and any such sub-agent, and shall apply to their respective activities
in connection with the syndication of the credit facilities provided for herein as well as activities as the Agent. 
 Section
7.8 Exemption of Payments From Trust Indenture Act. In the event that Citi or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the
“Trust Indenture Act”) in respect of any securities issued or guaranteed by the Borrower, the parties hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of the Advances, all
interest thereon and all other amounts payable hereunder or under any other Loan Document by or on behalf of Citi in its capacity as the Agent for the benefit of any Lender under any Loan Document (other than Citi or an Affiliate of Citi) and which
is applied in accordance with the Loan Documents shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act. 
 ARTICLE VIII 
 MISCELLANEOUS 

 Section 8.1 Amendments, Etc. No amendment or waiver of any provision of any Loan Document, nor consent to any
departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Majority Lenders and, in the case of any amendment, the Borrower, and then such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given; provided, however, that no amendment, waiver or consent shall, unless in writing and signed by all the Lenders, do any of the following: (a) waive, modify or
eliminate any of the conditions specified in Article III; (b) increase or extend the Commitments of the Lenders or subject the Lenders to any additional obligations, (c) reduce the principal of, or interest on, the Advances, any Applicable
Margin or any fees or other amounts payable hereunder (other than fees payable to the Agent for its own 
  

 48 

 account, or to any Lender pursuant to Section 2.13 or Section
2.17), (d) postpone any date fixed for any payment of principal of, or interest on, the Advances, or any fees or other amounts payable hereunder, (e) change the percentage of the Commitments or of the aggregate unpaid
principal amount of the Advances, or the number of Lenders, which shall be required for the Lenders or any of them to take any action hereunder, (f) amend this Section 8.1, (g) release any
collateral for the obligations of the Borrower hereunder or (h) change or waive any provision of Section 2.18 or any other provision of this Agreement or any other Loan Document requiring pro rata
treatment of the Lenders; and provided, further, that (i) no amendment, waiver or consent shall affect the rights or duties of the Agent under this Agreement or any Term Note, unless such amendment, waiver or consent is in writing
and signed by the Agent, in addition to the Lenders required above to take such action, (ii) that no amendment, waiver or consent shall change or waive any provision of Section 2.13 or Section
2.17, unless such amendment, waiver or consent is in writing and signed by each Lender directly affected thereby, in addition to the Lenders required above to take such action and (iii) that this Agreement may be amended and
restated without the consent of any Lender or the Agent if, upon giving effect to such amendment and restatement, such Lender or the Agent, as the case may be, shall no longer be a party to this Agreement (as so amended and restated) or have any
Commitment or other obligation hereunder and shall have been paid in full all amounts payable hereunder to such Lender or the Agent, as the case may be. Anything herein to the contrary notwithstanding, no Defaulting Lender shall have any right to
approve or disapprove any amendment, waiver or consent hereunder, except that in no event shall any amendment, waiver or consent purport to (A) reduce the principal of, or interest on, the Advances made by such Defaulting Lender, or any
Applicable Margin or any fees or other amounts payable to such Defaulting Lender, (B) postpone any date fixed for any payment of principal of, or interest on, the Advances made by such Defaulting Lender, or (C) amend this
Section 8.1 in a manner that affects such Defaulting Lender adversely, in each case without the affirmative consent of such Defaulting Lender, provided that if any such amendment, waiver or consent has been approved by
all Lenders which are not Defaulting Lenders, and such Defaulting Lender shall have failed to have furnished either its approval or disapproval of such amendment, waiver or consent within the period of ten Business Days after its receipt of a
written request to do so, then such Defaulting Lender shall be deemed to have given its affirmative consent. 
 If the Borrower and the Agent
agree in writing in their discretion that a Lender that is a Defaulting Lender or a Potential Defaulting Lender should no longer be deemed to be a Defaulting Lender or Potential Defaulting Lender, as the case may be, the Agent will so notify the
parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein, such Lender will, to the extent applicable, purchase such portion of outstanding Advances of the other Lenders and/or make
such other adjustments as the Agent may determine to be necessary to cause the Credit Exposure of the such Lender to be in accordance with its Percentage immediately prior to its becoming a Defaulting Lender or a Potential Defaulting Lender,
whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender and will be a Non-Defaulting Lender (and such Percentage of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing);
provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise
expressly agreed by the affected parties, no change hereunder from Defaulting Lender or Potential Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s
having been a Defaulting Lender or Potential Defaulting Lender. 
  

 49 

 Section 8.2 Notices, Etc. (a) All notices and other communications provided for
hereunder and under the other Loan Documents shall be in writing, or by any telecommunication device capable of creating a written record (including electronic mail), and and addressed to the party to be notified as follows:

 (b) All notices, demands, requests, consents and other communications described in clause (a) shall be effective (i) if delivered by hand,
including any overnight courier service, upon personal delivery, and (ii) if delivered by electronic mail or any other telecommunications device, when transmitted to an electronic mail address (or by another means of electronic delivery) as

 (c) Notwithstanding clauses (a) and (b) (unless the Agent requests that the provisions of clause (a) and (b) be followed) and any
other provision in this Agreement or any other Loan Document providing for the delivery of any Approved Electronic Communication by any other means, the Borrower shall deliver all Approved Electronic Communications to the Agent by properly
transmitting such Approved Electronic Communications in an electronic/soft medium in a format acceptable to the Agent to oploanswebadmin@citigroup.com or such other electronic mail address (or similar means of electronic delivery) as the Agent may
notify to the Borrower. Nothing in this clause (c) shall prejudice the right of the Agent or any Lender to deliver any Approved Electronic Communication to the Borrower in any manner authorized in this Agreement or to request that the Borrower
effect delivery in such manner. 
 Section 8.3 No Waiver; Remedies. No failure on the part of any Lender or the Agent to
exercise, and no delay in exercising, any right hereunder or under any Term Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other 
  

 50 

 or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law. 
 Section 8.4 Costs, Expenses, Taxes and Indemnification. 
 (a) The Borrower agrees to pay on demand all costs and expenses of the Agent in connection with the preparation (including, without
limitation, printing costs), negotiation, execution, delivery, modification and amendment of this Agreement and the other Loan Documents, and the other documents and instruments to be delivered hereunder and thereunder, including, without
limitation, the reasonable fees and out of pocket expenses of counsel for the Agent with respect thereto and with respect to the administration of, and advising the Agent as to its rights and responsibilities under, this Agreement and the other Loan
Documents. The Borrower further agrees to pay on demand all costs and expenses, if any (including, without limitation, reasonable counsel fees and expenses of the Agent and each Lender), in connection with the enforcement and workout (whether
through negotiations, legal proceedings or otherwise) of this Agreement and the other Loan Documents and the other documents and instruments to be delivered hereunder and thereunder, including, without limitation, reasonable counsel fees and
expenses in connection with the enforcement of rights under this Section 8.4(a). In addition, the Borrower shall pay any and all stamp and other taxes payable or determined to be payable in connection with the execution and delivery of
this Agreement and the other Loan Documents, and the other documents and instruments to be delivered hereunder and thereunder, and agrees to save the Agent and each Lender harmless from and against any and all liabilities with respect to or
resulting from any delay in paying or omission to pay such taxes. 
 (b) If any payment of principal of, or Conversion of, any Eurodollar
Rate Advance is made other than on the last day of the Interest Period for such Advance as a result of a payment or Conversion pursuant to Section 2.10(f), Section 2.11, Section 2.12 or
Section 2.14 or acceleration of the maturity of the Advances pursuant to Section 6.1 or for any other reason, or if any assignment of any Eurodollar Rate Advance is made other than on the last
day of the Interest Period for such Advance as a result of an assignment pursuant to Section 2.20, the Borrower shall, upon demand by any Lender (with a copy of such demand to the Agent), pay to the Agent for the account of such Lender any amounts
required to compensate such Lender for any additional losses, costs or expenses which it may reasonably incur as a result of such payment or Conversion or assignment, including, without limitation, any loss, cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance. 
 (c) The Borrower hereby
agrees to indemnify and hold each Lender, the Agent and their respective officers, directors, employees, professional advisors and affiliates (each, an “Indemnified Person”) harmless from and against any and all claims,
damages, losses, liabilities, costs or expenses (including reasonable attorney’s fees and expenses, whether or not such Indemnified Person is named as a party to any proceeding or is otherwise subjected to judicial or legal process arising from
any such proceeding) which any of them may incur or which may be claimed against any of them by any Person including the Borrower (except for such claims, damages, losses, liabilities, costs and expenses resulting from such Indemnified Person’s
gross negligence or willful misconduct): 
 (i) by reason of or resulting from the execution, delivery or performance of any
of the Loan Documents or any transaction contemplated thereby, or the use by the Borrower of the proceeds of any Advance; 
  

 51 

 (ii) in connection with any documentary taxes, assessments or charges made by any
governmental authority by reason of the execution and delivery of any of the Loan Documents; 
 (iii) in connection with or
resulting from the utilization, storage, disposal, treatment, generation, transportation, release or ownership of any Hazardous Substance (A) at, upon, or under any property of the Borrower or any of its Affiliates or (B) by or on behalf
of the Borrower or any of its Affiliates at any time and in any place; or 
 (iv) in connection with or resulting from the use
by unintended recipients of any information or other materials distributed by it through the internet, SyndTrak or other similar transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated
hereby or thereby. 
 In case any action or proceeding is instituted involving any Indemnified Person for which indemnification is to be
sought hereunder by such Indemnified Person, then such Indemnified Person will promptly notify the Borrower of the commencement of any action or proceeding; provided, however, that the failure so to notify the Borrower will not relieve
the Borrower from any liability that the Borrower may have to such Indemnified Person pursuant hereto or from any liability that it may have to such Indemnified Person other than pursuant hereto. Notwithstanding the above, following such
notification, the Borrower may elect in writing to assume the defense of such action or proceeding, and, upon such election, the Borrower will not, as long as it diligently conducts such defense, be liable for any legal costs subsequently incurred
by such Indemnified Person (other than reasonable costs of investigation and providing evidence) in connection therewith, unless (i) the Borrower has failed to provide counsel reasonably satisfactory to such Indemnified Person in a timely
manner (it being agreed that Foley & Lardner LLP shall be deemed to be reasonably satisfactory counsel for such purpose), (ii) the Indemnified Person determines in good faith that joint representation would be inappropriate or
(iii) the Indemnified Person reasonably determines that there may be legal defenses available to it which are different from, or in addition to those available to the Borrower. If the Borrower assumes the defense of any such action or
proceeding, (a) it will be conclusively established for purposes of this Agreement that the claims made with respect thereto are subject to indemnification hereunder; (b) no compromise or settlement of such claims may be effected by the
Borrower without the Indemnified Person’s consent and (c) the Indemnified Person will have no liability with respect to any compromise or settlement of such claims effected without its consent. Notwithstanding the foregoing, if any
Indemnified Person determines in good faith that there is a reasonable probability that any action or proceeding may adversely affect it or its affiliates other than as a result of monetary damages for which it would be entitled to indemnification
hereunder, such Indemnified Person many, by notice to the Borrower, assume the exclusive right to defend, compromise, or settle such action or proceeding, but the Borrower will not be bound (but will retain its indemnification obligations hereunder)
by any 
  

 52 

 determination of an action or proceeding so defended or any compromise or settlement effected without its
consent (which may not be unreasonably withheld). In connection with any one action or proceeding, the Borrower will not be responsible for the fees and expenses of more than one separate law firm (in addition to local counsel) for all Indemnified
Persons. 
 (d) The Borrower’s obligations under this Section 8.4 shall survive the repayment
of all amounts owing to the Lenders hereunder and the termination of the Commitments. If and to the extent that the obligations of the Borrower under this Section 8.4 are unenforceable for any reason, the Borrower agrees
to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law. 
 Section 8.5 Right of Set-off. 
 (a) Upon (i) the occurrence and during the continuance of any Event of
Default and (ii) the making of the request or the granting of the consent by the Majority Lenders specified by Section 6.1 to authorize the Agent to declare all amounts owing hereunder due and payable pursuant to the
provisions of Section 6.1, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final)
at any time held and other indebtedness at any time owing by such Lender to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under any Loan Document, irrespective of
whether or not such Lender shall have made any demand under such Loan Document and although such obligations may be unmatured. Each Lender agrees promptly to notify the Borrower after any such set-off and application made by such Lender,
provided that the failure to give such notice shall not affect the validity of such set off and application. The rights of each Lender under this Section are in addition to other rights and remedies (including, without limitation, other
rights of set-off) which such Lender may have. 
 (b) The Borrower agrees that it shall have no right of set-off, deduction or
counterclaim in respect of its obligations hereunder, and that the obligations of the Lenders hereunder are several and not joint. Nothing contained herein shall constitute a relinquishment or waiver of the Borrower’s rights to any independent
claim that the Borrower may have against the Agent or any Lender for the Agent’s or such Lender’s, as the case may be, gross negligence or willful misconduct; provided that no Lender shall be liable for the conduct of the Agent or
any other Lender; provided, further, that the Agent shall not be liable for the conduct of any Lender; provided, however that none of the Agent or any Lender shall be liable to the Borrower for any amounts representing indirect,
special, consequential or punitive damages suffered by the Borrower. 
 Section 8.6 Binding Effect.
This Agreement shall become effective when it shall have been executed by the Borrower and the Agent and when the Agent shall have been notified in writing by each Bank that such Bank has executed it and thereafter shall be binding upon and inure to
the benefit of the Borrower, the Agent and each Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the
Lenders. 
 Section 8.7 Assignments and Participations. 
  

 53 

 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Agent and each Lender and
no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the
provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party
hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent
provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

 (b) Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment and the Term Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions: 
 (i) Minimum Amounts. 
 (A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Term Loans at the time owing to it or in the case of an assignment to a Lender, an
Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and 
 (B) in any case not
described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Term Loans of the assigning Lender subject to each such
assignment (determined as of the date the Lender Assignment with respect to such assignment is delivered to the Agent or, if “Trade Date” is specified in the Lender Assignment, as of the Trade Date) shall not be less than $1,000,000,
unless each of the Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed). 
 (ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the
assigning Lender’s rights and obligations under this Agreement with respect to the Term Loan or the Commitment assigned. 
  

 54 

 (iii) Required Consents. No consent shall be required for any assignment except to
the extent required by paragraph (b)(i)(B) of this Section and, in addition: 
 (A) the consent of the Borrower (such consent
not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;
and 
 (B) the consent of the Agent (such consent not to be unreasonably withheld or delayed) shall be required for
assignments in respect of (i) a Commitment if such assignment is to a Person that is not a Lender with a Commitment hereunder, an Affiliate of such Lender or an Approved Fund with respect to such Lender or (ii) a Term Loan to a Person who
is not a Lender, an Affiliate of a Lender or an Approved Fund; 
 (iv) Lender Assignment. The parties to each
assignment shall execute and deliver to the Agent a Lender Assignment, together with a processing and recordation fee of $3500 (which, for the avoidance of doubt, shall not be paid by the Borrower), and the assignee, if it is not a Lender, shall
deliver to the Agent an Administrative Questionnaire. 
 (v) No Assignment to Borrower. No such assignment shall be
made to the Borrower or any of the Borrower’s Affiliates or Subsidiaries. 
 (vi) No Assignment to Natural
Persons. No such assignment shall be made to a natural person. 
 Subject to acceptance and recording thereof by the Agent pursuant to
paragraph (c) of this Section, from and after the effective date specified in each Lender Assignment, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Lender Assignment, have the
rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Lender Assignment, be released from its obligations under this Agreement (and, in the case of a Lender
Assignment covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.13, 2.17
and 8.4 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph
shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section. 
 (c) The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in the United States a copy of each
Lender Assignment delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Term Loans owing to, each Lender pursuant to the terms hereof from time to time (the
“Register”). The entries in the Register shall be conclusive, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all
purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. 
  

 55 

 (d) Any Lender may at any time, without the consent of, or notice to, the Borrower or the Agent, sell
participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations
under this Agreement (including all or a portion of its Commitment and/or the Term Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and
obligations under this Agreement. 
 Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that
such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver to any provision, governing or affecting any principal amount, interest rate or maturity of any obligations, that affects such Participant. Subject to paragraph (e) of
this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.13 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this
Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.5 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18 as
though it were a Lender. 
 (e) A Participant shall not be entitled to receive any greater payment under Section 2.13 than
the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that
would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 2.17(e) as though it were a Lender. 
 (f) Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall
release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 Section 8.8 Confidentiality. Each of the Agent and the Lenders agrees to maintain the confidentiality of the Confidential Information (as defined below), except that Confidential Information may be
disclosed (a) to its Affiliates as needed in connection with this Agreement and to its and such of its Affiliates’ respective managers, administrators, trustees, partners, directors, officers, employees, agents, advisors and other
representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Confidential Information and instructed to keep such Confidential Information 
  

 56 

 confidential), (b) to the extent requested by any regulatory authority purporting to have jurisdiction over it
(including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party
hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan 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 or (ii) any actual or prospective party (or its managers, administrators, trustees, partners, directors, officers, employees, agents, advisors and other representatives) to any swap, derivative or other transaction under which
payments are to be made by reference to the Borrower and its obligations, this Agreement or payments hereunder, (iii) any rating agency, or (iv) the CUSIP Service Bureau or any similar organization, (g) with the consent of the
Borrower or (h) to the extent such Confidential Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Agent, any Lender, or any of their respective Affiliates on
a nonconfidential basis from a source other than the Borrower. 
 For purposes of this Section, “Confidential Information” means
all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Subsidiaries or any of their respective businesses, other than any such information that is available to the Agent or any Lender on a
nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries. Any Person required to maintain the confidentiality of Confidential 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 Confidential Information as such Person would accord to its own confidential information. 
 Section 8.9 WAIVER OF JURY TRIAL. THE AGENT, THE LENDERS AND THE BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
VERBAL OR WRITTEN), OR ACTIONS OF THE AGENT, THE LC ISSUING BANK, SUCH LENDERS OR THE BORROWER. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE AGENT AND THE LENDERS ENTERING INTO THIS AGREEMENT. 
 Section 8.10 Governing Law. This Agreement and the other Loan Documents shall be governed by, and construed in accordance
with, the laws of the State of New York. The Borrower, each Lender and the Agent (i) irrevocably submits to the non-exclusive jurisdiction of any New York State court or Federal court sitting in New York City in any action arising out of any
Loan Document, (ii) agrees that all claims in such action may be decided in such court, (iii) waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum and (iv) consents to the service of process by
mail, provided that a copy shall be promptly sent by overnight courier to Foley & Lardner LLP, U.S. Bank Center, 777 East Wisconsin Avenue, Milwaukee, Wisconsin 53202-5367, Attention: Emory Ireland, Esq. A final judgment in any such
action shall be conclusive and may be enforced in other jurisdictions. Nothing herein shall affect the right of any party to serve legal process in any manner permitted by law or affect its right to bring any action in any other court. 

 

 57 

 Section 8.11 Relation of the Parties; No Beneficiary. No term, provision or
requirement, whether express or implied, of any Loan Document, or actions taken or to be taken by any party thereunder, shall be construed to create a partnership, association, or joint venture between such parties or any of them. No term or
provision of the Loan Documents shall be construed to confer a benefit upon, or grant a right or privilege to, any Person other than the parties thereto. 
 Section 8.12 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be
deemed to be an original and all of which taken together shall constitute one and the same agreement. 
 Section 8.13
Severability. To the extent any provision of this Agreement is prohibited by or invalid under the applicable law of any jurisdiction, such provision shall be ineffective only to the extent of such prohibition or invalidity and only in
such jurisdiction, without prohibiting or invalidating such provision in any other jurisdiction or the remaining provisions of this Agreement in any jurisdiction. 
 Section 8.14 Disclosure of Information. The Borrower agrees and consents to the Agent’s disclosure of information relating to this transaction to Gold Sheets and other similar
bank trade publications. Such information will consist of deal terms and other information customarily found in such publications. 
 Section 8.15 USA Patriot Act Notice. Each Lender that is subject to the PATRIOT Act and the Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the
PATRIOT Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Agent, as applicable, to
identify the Borrower in accordance with the PATRIOT Act. 
 Section 8.16 Entire Agreement. This Agreement,
together with any Term Note and any other agreements, instruments and other documents required to be executed and delivered in connection herewith, represents the entire agreement of the parties hereto and supersedes all prior agreements and
understandings of the parties with respect to the subject matter covered hereby. 
 Section 8.17 Treatment of
Information. (a) Certain of the Lenders may enter into this Agreement and take or not take action hereunder or under the other Loan Documents on the basis of information that does not contain material non-public information with
respect to the Borrower or its securities (“Restricting Information”). Other Lenders may enter into this Agreement and take or not take action hereunder or under the other Loan Documents on the basis of information that may
contain Restricting Information. Each Lender acknowledges that United States federal and state securities laws prohibit any person from purchasing or selling securities on the basis of material, non-public information concerning the such issuer of
such securities or, 
  

 58 

 subject to certain limited exceptions, from communicating such information to any other Person. Neither the Agent nor any
of its Related Parties shall, by making any Communications (including Restricting Information) available to a Lender, by participating in any conversations or other interactions with a Lender or otherwise, make or be deemed to make any statement
with regard to or otherwise warrant that any such information or Communication does or does not contain Restricting Information nor shall the Agent or any of its Related Parties be responsible or liable in any way for any decision a Lender may make
to limit or to not limit its access to Restricting Information. In particular, none of the Agent nor any of its Related Parties (i) shall have, and the Agent, on behalf of itself and each of its Related Parties, hereby disclaims, any duty to
ascertain or inquire as to whether or not a Lender has or has not limited its access to Restricting Information, such Lender’s policies or procedures regarding the safeguarding of material, nonpublic information or such Lender’s compliance
with applicable laws related thereto or (ii) shall have, or incur, any liability to the Borrower or any Lender or any of their respective Related Parties arising out of or relating to the Agent or any of its Related Parties providing or not
providing Restricting Information to any Lender. 
 (b) The Borrower agrees that (i) all Communications it provides to the Agent
intended for delivery to the Lenders shall be clearly and conspicuously marked “PUBLIC” if such Communications do not contain Restricting Information which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently
on the first page thereof, and (ii) by marking Communications “PUBLIC,” the Borrower shall be deemed to have authorized the Agent and the Lenders to treat such Communications as either publicly available information or not material
information (although, in this latter case, such Communications may contain sensitive business information and, therefore, remain subject to the confidentiality undertakings of Section 8.8) with respect to the Borrower or
its securities for purposes of United States Federal and state securities laws. Neither the Agent nor any of its Affiliates shall be responsible for any statement or other designation by the Borrower regarding whether a Communication contains or
does not contain material non-public information with respect to the Borrower or its securities nor shall the Agent or any of its Affiliates incur any liability to the Borrower, any Lender or any other Person for any action taken by the Agent or any
of its Affiliates based upon such statement or designation, including any action as a result of which Restricting Information is provided to a Lender that may decide not to take access to Restricting Information. Nothing in this Section
8.17 shall modify or limit a Lender’s obligations under Section 8.8 with regard to Communications and the maintenance of the confidentiality of or other treatment of Information. 
 (c) Each Lender acknowledges that circumstances may arise that require it to refer to Communications that might contain Restricting Information.
Accordingly, each Lender agrees that it will nominate at least one designee to receive Communications (including Restricting Information) on its behalf and identify such designee (including such designee’s contact information) on such
Lender’s Administrative Questionnaire. Each Lender agrees to notify the Agent from time to time of such Lender’s designee’s e-mail address to which notice of the availability of Restricting Information may be sent by electronic
transmission. 
 (d) Each Lender acknowledges that Communications delivered hereunder and under the other Loan Documents may contain
Restricting Information and that such Communications are available to all Lenders generally. Each Lender that elects not to take access to Restricting Information does so voluntarily and, by such election, acknowledges and 
  

 59 

 agrees that the Agent and other Lenders may have access to Restricting Information that is not available to such electing
Lender. None of the Agent nor any Lender with access to Restricting Information shall have any duty to disclose such Restricting Information to such electing Lender or to use such Restricting Information on behalf of such electing Lender, and shall
not be liable for the failure to so disclose or use, such Restricting Information. 
 (e) The provisions of the foregoing clauses of this
Section 8.17 are designed to assist the Agent, the Lenders and the Borrower, in complying with their respective contractual obligations and applicable law in circumstances where certain Lenders express a desire not to
receive Restricting Information notwithstanding that certain Communications hereunder or under the other Loan Documents or other information provided to the Lenders hereunder or thereunder may contain Restricting Information. Neither the Agent nor
any of its Related Parties warrants or makes any other statement with respect to the adequacy of such provisions to achieve such purpose nor does the Agent or any of its Related Parties warrant or make any other statement to the effect that the
Borrower’s or a Lender’s adherence to such provisions will be sufficient to ensure compliance by the Borrower or such Lender with its contractual obligations or its duties under applicable law in respect of Restricting Information and each
of the Lenders and the Borrower assumes the risks associated therewith.

 FOR VALUE RECEIVED, the undersigned (the
“Borrower”), hereby promises to pay to

as therein defined), among the Borrower, the Lenders parties thereto, and Citibank, N.A., as Agent. 
 The Borrower promises to pay interest
on the unpaid principal amount of each Term Loan owing to the Lender from the date of such Term Loan until such principal amount is paid in full, at such interest rates and at such times as provided in the Credit Agreement. All payments of principal
and interest shall be made to the Agent for the account of the Lender in Dollars in same day funds at the Agent’s address referred to in Section 8.2 of the Credit Agreement. If any amount is not paid in full when due hereunder, such unpaid

 This Term Note is one of the Term Notes referred to in the Credit Agreement, is entitled to the benefits thereof and may be prepaid in whole or in part
subject to the terms and conditions provided therein. Upon the occurrence and continuation of one or more of the Events of Default specified in the Credit Agreement, all amounts then remaining unpaid on this Term Note shall become, or may be
declared to be, immediately due and payable all as provided in the Credit Agreement. Term Loans made by the Lender shall be evidenced by one or more accounts maintained by the Lender in accordance with its usual practice. The Lender may also attach
schedules to this Term Note and endorse thereon the date, amount and maturity of its Advances and payments with respect thereto. 
 Except as
otherwise provided in the Credit Agreement, the Borrower, for itself, its successors and assigns, hereby waives diligence, presentment, protest and demand and notice of protest, demand, dishonor and non-payment of this Term Note.

 EXHIBIT 3.1(A)(VIII)(A) 
 FORM OF OPINION OF 
 FOLEY & LARDNER LLP 

 September 16, 2009 
 To each of the Banks parties to the 
     Credit Agreement referred to below, 
     and to Citibank, N.A., as Administrative Agent 
 Re: Alliant Energy Corporation 
 Ladies and Gentlemen: 
 This opinion is furnished to you pursuant to Section 3.1(a)(viii)(A) of the Credit Agreement, dated as of September 16, 2009 (the
“Credit Agreement”), among Alliant Energy Corporation (the “Borrower”), the Banks parties thereto and Citibank, N.A., as Administrative Agent (the “Agent”). Terms defined in the
Credit Agreement and not otherwise defined herein are used herein as therein defined. 
 We have acted as counsel for the
Borrower in connection with the preparation, execution and delivery of, and the closing on this date (the “Closing”) under, the Credit Agreement and the other Loan Documents. 
 In that capacity we have examined: 
 (i) the Credit Agreement; 
 (ii) the Fee Letter, dated as of the
date hereof, by and between the Borrower and the Agent (the “Agent Fee Letter”); 
 (iii)
the Fee Letter, dated as of the date hereof, by and between the Borrower and JPMorgan Chase Bank, N.A. (the “JPM Fee Letter” and collectively with the Agent Fee Letter the “Fee Letters”); 

(iv) the Articles of Incorporation of the Borrower and all amendments thereto (the “Borrower
Charter”); and 
 (v) the by-laws of the Borrower and all amendments thereto (the
“Borrower By-laws”). 
 In addition, we have examined the originals, or copies certified to our
satisfaction, of such other corporate records of the Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments and other documents, as we have deemed necessary as a basis for the opinions expressed
below. As to questions of fact material to such opinions, we have, when relevant facts were not independently established by us, relied upon certificates of the Borrower or its officers, including the officer’s certificate annexed hereto as
Exhibit A (the “Officer’s Certificate”), or of public officials. 
  

 September 16, 2009 
 Page 2 
 We have assumed (i) the due execution and delivery, pursuant to due
authorization, of the Credit Agreement by all parties to the Credit Agreement (other than the Borrower), (ii) the authenticity of all such documents submitted to us as originals, (iii) the genuineness of all signatures (other than those of
the Borrower), (iv) the conformity to the originals of all such documents submitted to us as copies and (v) the enforceability of all documents against parties thereto other than the Borrower. 
 Our opinions expressed herein are limited to the laws of the State of New York, the laws of the State of Wisconsin and the Federal laws of
the United States of America in effect on the date hereof as they presently apply and we express no opinion as to the laws of any other jurisdiction. 
 Based upon the foregoing, but subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that: 
 1. Based solely upon a certificate issued by the Wisconsin Department of Financial Institutions, the Borrower is a validly existing
corporation, has filed its most recent annual report required by the Wisconsin Statutes and has not filed Articles of Dissolution as of the date of such certificate. 
 2. The execution, delivery and performance by the Borrower of the Credit Agreement and the Fee Letters are within the Borrower’s corporate powers, have been duly authorized by all necessary corporate
action, and do not contravene (a) the Borrower Charter or the Borrower By-laws, or (b) any law, rule or regulation, or (c) any order or judgment of which we have knowledge applicable to the Borrower. The Credit Agreement and the Fee
Letters have been duly executed and delivered on behalf of the Borrower. 
 3. No Governmental Approval is required in
connection with the execution, delivery or performance by the Borrower of any Loan Document, or the enforcement thereof by the Agent and the Lenders. 
 4. The Credit Agreement and the Fee Letters are the legal, valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with their respective terms. 
 5. The Borrower is not an “investment company” as defined in the Investment Company Act of 1940, as amended. 
 6. Neither the execution and delivery of the Loan Documents by the Borrower, nor the Borrower’s performance of its obligations
thereunder, will result in any violation of Regulation U, T or X of the Board of Governors of the Federal Reserve System.

 Wherever we indicate that our opinion with respect to the existence or
absence of facts is “to our knowledge” or the like, our opinion is, with your permission, based solely on the Officer’s Certificate and the current conscious awareness of facts or other information of the attorneys currently with our
firm who have represented the Borrower or any Subsidiary in connection with the transactions contemplated by the Credit Agreement. 
 Our opinion set forth in paragraph 4 above is limited by: 
  

	 	(a)	Applicable bankruptcy, receivership, reorganization, insolvency, moratorium, fraudulent conveyance or transfer, and other laws and judicially developed doctrines
relating to or affecting creditors’ rights and remedies generally; 

  

	 	(b)	General principles of equity, regardless of whether such enforcement is considered in a proceeding in equity or at law, and limitations on the availability of specific
performance, injunctive relief and other equitable remedies; 

  

	 	(c)	The possibility that certain rights, remedies and waivers in the Loan Documents may not be enforceable; nevertheless, such unenforceability will not render any of the
Loan Documents invalid as a whole or preclude (i) judicial enforcement of the obligation of Borrower to repay the principal, together with interest thereon (to the extent not deemed a penalty) as provided in the Credit Agreement; or
(ii) acceleration of the obligation of Borrower to repay such principal, together with such interest, upon a material default in a material provision of the Loan Documents, and each Loan Document contains legally adequate provisions for the
practical realization of the principal legal rights and benefits afforded by it; and 

  

	 	(d)	The requirement that the enforcing party act in good faith in exercising its rights under the Loan Documents. 

 These opinions are given as of the date hereof, they are intended to apply only to those facts and circumstances that exist as of the date
hereof, and we assume no obligation or responsibility to update or supplement these opinions to reflect any facts or circumstances that may hereafter come to our attention or any changes in laws that may hereafter occur, or to inform the addressee
of any change in circumstances occurring after the date hereof that would alter the opinions rendered herein.

 EXHIBIT 3.1(a)(viii)(B) 
 September 16, 2009 
 To each of the Banks parties to the 
     Credit Agreement referred to below, 
     and to Citibank, N.A., as Administrative Agent 
 Re: Alliant Energy Corporation 
 Ladies and Gentlemen: 
 This opinion is furnished to you
pursuant to Section 3.1(a)(viii)(B) of the Credit Agreement, dated as of September 16, 2009 (the “Credit Agreement”), among Alliant Energy Corporation (the “Borrower”), the Banks parties
thereto and Citibank, N.A., as Administrative Agent. Terms defined in the Credit Agreement and not otherwise defined herein are used herein as therein defined. 
 I am Senior Attorney of the Borrower and have acted as such in connection with the preparation, execution and delivery of, and the closing on this date under (the “Closing”), the Credit
Agreement and the other Loan Documents. 
 In that capacity I have examined, or have arranged for the examination by an attorney or attorneys
under my general supervision of: 
 (i) the Credit Agreement; 
 (ii) the Fee Letter, dated as of the date hereof, by and between the Borrower and the Agent (the “Agent Fee
Letter”); 
 (iii) the Fee Letter, dated as of the date hereof, by and between the Borrower and JPMorgan Chase
Bank, N.A. (the “JPM Fee Letter” and collectively with the Agent Fee Letter the “Fee Letters”); 
 (iv) the Articles of Incorporation of the Borrower and all amendments thereto (the “Borrower Charter”); and 
 (v) the by-laws of the Borrower and all amendments thereto (the “Borrower By-laws”). 
 In addition, I, or an attorney or attorneys under my general supervision, have examined the originals, or copies certified to my or their satisfaction,
of such other corporate records of the 

 Borrower, certificates of public officials and of officers of the Borrower, and agreements, instruments and other
documents, as I or such attorneys have deemed necessary as a basis for the opinions expressed below. As to questions of fact material to such opinions, I or such attorneys have, when relevant facts were not independently established by me or by
them, relied upon certificates of the Borrower or its officers or of public officials. 
 I have assumed (i) the due execution and
delivery, pursuant to due authorization, of the Credit Agreement by all parties to such document (other than the Borrower), (ii) the authenticity of all such documents submitted to me as originals, (iii) the genuineness of all signatures
(other than those of the Borrower) and (iv) the conformity to the originals of all such documents submitted to me as copies. 
 I, or an
attorney or attorneys under my general supervision, have made such examination of law as in my or their judgment is necessary or appropriate for purposes of this opinion. I and such attorneys do not, however, purport to be qualified to pass upon,
and express no opinion as to, the laws of any jurisdiction other than the laws of the State of Wisconsin. 
 Based upon and subject to the
foregoing, I am of the opinion that: 
 1. The Borrower is a corporation duly organized, validly existing and in good standing under the laws
of the State of Wisconsin and is duly qualified to do business in, and is in good standing in, all other jurisdictions where the nature of its business or the nature of the property owned or leased by it makes such qualification necessary, except
where the failure to so qualify would not have a material adverse effect on the business, financial condition, results of operations or prospects of the Borrower and its Subsidiaries, taken as a whole. 
 2. The execution, delivery and performance by the Borrower of the Credit Agreement and Fee Letters are within the Borrower’s corporate powers, have
been duly authorized by all necessary corporate action, and do not contravene (a) the Borrower Charter or the Borrower By-laws; (b) any law, rule, regulation, order or judgment applicable to the Borrower; (c) any contractual
restriction arising under any indenture or other agreement or instrument evidencing indebtedness of the Borrower; or (d) to my knowledge, any other legal or contractual restriction binding on or affecting the Borrower or its properties; and
such execution, delivery and performance do not result in or require the creation or imposition of any Lien upon or with respect to any of its properties under any indenture or other agreement or instrument evidencing indebtedness of the Borrower.
The Credit Agreement and Fee Letters has been duly executed and delivered on behalf of the Borrower. 
 3. No Governmental Approval is
required in connection with the execution, delivery or performance by the Borrower of any Loan Document, or the enforcement thereof by the Agent and the Lenders. 
 4. There is no pending or, to my knowledge, threatened action or proceeding affecting the Borrower or its properties before any court, governmental agency or arbitrator, that could reasonably be expected, if adversely
determined, to materially and adversely affect the business, financial condition, operations, results of operations or prospects of the Borrower, or 
  

 2 

 affect the legality, validity or enforceability of the Credit Agreement or any other Loan Document. 
 My opinions herein are limited to the matters expressed herein, and no other opinions are or may be implied or inferred beyond the matters expressly
stated. Except as expressly set forth herein, this opinion is being provided solely for the purpose of complying with the requirements of the Agent and the Lenders in connection with the Credit Agreement, and is being rendered solely for the benefit
of the addressees hereof, their participants, assignees and transferees. This opinion may not be used or relied upon for any other purpose, relied upon by any other party, or filed with or disclosed to any governmental authority other than a court
in connection with the enforcement or protection of the rights or remedies of the Agent and/or the Lenders under the Credit Agreement or to a banking examiner or regulator in connection with an examination of the Agent and/or the Lenders by such
governmental authority, without my prior written consent. I authorize Foley & Lardner LLP, counsel to the Borrower, to rely on this opinion respecting matters covered by or relating to the laws of the State of Wisconsin. 
 The opinions expressed herein are given as of the date hereof, and I make no undertaking to supplement such opinions if, after the date hereof, facts or
circumstances come to my attention or changes in law occur which could affect such opinions. 
 Very truly yours,
