The Borrowers shall give all such notices requesting, the advance, continuation, or conversion of a Borrowing to the Administrative Agent by telephone, facsimile or electronic means (which notice shall be irrevocable once given and, if by telephone, shall be promptly confirmed in writing). Notwithstanding the foregoing, the Borrowers shall not be permitted to request a Eurodollar Loan, convert a Base Rate Loan to a Eurodollar Loan or continue a Eurodollar Loan for new Interest Period if an Event of Default shall have occurred and be continuing. Notices of the continuation of a Borrowing of Eurodollar Loans for an additional Interest Period or of the conversion of part or all of a Borrowing of Base Rate Loans into Eurodollar Loans must be given by no later than 12:00 noon (Chicago time) at least three (3) Business Days before the date of the requested continuation or conversion. Notices of the conversion of part or all of a Borrowing of Eurodollar Loans into Base Rate Loans must be given no later than 11:00 a.m. (Chicago time) on the date of the requested conversion. All such notices concerning the advance, continuation, or conversion of a Borrowing shall be irrevocable once given and shall specify the Borrower who is requesting the advance, continuation, or conversion of the applicable Borrowing, the date of the requested advance, continuation or conversion of a Borrowing (which shall be a Business Day), the amount of the requested Borrowing to be

advanced, continued, or converted, the type of Loans to comprise such new, continued or converted Borrowing and, if such Borrowing is to be comprised of Eurodollar Loans, the Interest Period applicable thereto. All such notices shall be in the form of a Notice of Borrowing, unless otherwise consented to by the Administrative Agent; provided that the Borrowers agree that the Administrative Agent may rely on any telephonic, facsimile or electronic notice given by any person it in good faith believes is an Authorized Representative without the necessity of independent investigation, and in the event any such notice by telephone conflicts with any written confirmation, such telephonic notice shall govern if the Administrative Agent has acted in reliance thereon. There may be no more than six different Interest Periods in effect at any one time.

(b) Notice to the Lenders. The Administrative Agent shall give prompt telephonic, facsimile or electronic notice to each Lender of any notice from a Borrower received pursuant to Section 2.4(a) above. The Administrative Agent shall give notice to such Borrower and each Lender by like means of the interest rate applicable to each Borrowing of Eurodollar Loans.

(c) Borrower’s Failure to Notify. If a Borrower fails to give notice pursuant to Section 2.4(a) above of the continuation or conversion of any outstanding principal amount of a Borrowing of Eurodollar Loans before the last day of its then current Interest Period within the period required by Section 2.4(a) and has not notified the Administrative Agent within the period required by Section 2.7(a) that it intends to prepay such Borrowing, such Borrowing shall automatically be converted into a Borrowing of Base Rate Loans, subject to Section 6.2 hereof. The Administrative Agent shall promptly notify the Lenders of a Borrower’s failure to so give a notice under Section 2.4(a).

(d) Disbursement of Loans. Not later than 12:00 noon (New York time) on the date of any requested advance of a new Borrowing of Eurodollar Loans, and not later than 2:00 p.m. (New York time) on the date of any requested advance of a new Borrowing of Base Rate Loans, subject to Section 6 hereof, each Lender shall make available its Loan comprising part of such Borrowing in funds immediately available at the principal office of the Administrative Agent in New York, New York.

(e) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.4(d) and may, in reliance upon such assumption, make available to the applicable Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and applicable Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to such Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined

by the Administrative Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by a Borrower, the interest rate applicable to such Loans. If such Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to such Borrower the amount of such interest paid by such Borrower for such period. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing. Any payment by such Borrower shall be without prejudice to any claim such Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

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

Section 2.5 Interest Periods. As provided in Section 2.4(a) hereof, at the time of each request of a Borrowing of Eurodollar Loans, a Borrower shall select an Interest Period applicable to such Loans from among the available options. The term “Interest Period” means the period commencing on the date a Borrowing of Eurodollar Loans is advanced, continued, or created by conversion and ending 1, 2, 3, or 6 months thereafter; provided, however, that:

(a) a Borrower may not select an Interest Period for a Loan that extends beyond the Applicable Repayment Date for such Loan;

(b) whenever the last day of any Interest Period would otherwise be a day that is not a Business Day, the last day of such Interest Period shall be extended to the next succeeding Business Day; provided that, if such extension would cause the last day of an Interest Period to occur in the following calendar month, the last day of such Interest Period shall be the immediately preceding Business Day; and

(c) for purposes of determining an Interest Period, a month means a period starting on one day in a calendar month and ending on the numerically corresponding day in the next calendar month; provided, however, that if there is no numerically corresponding day in the month in which such an Interest Period is to end or if such an Interest Period begins on the last Business Day of a calendar month, then such Interest Period shall end on the last Business Day of the calendar month in which such Interest Period is to end.

Section 2.6 Maturity of Loans. Unless an earlier maturity is provided for hereunder (whether by acceleration or otherwise), all Obligations (including principal and interest on all outstanding Loans) shall mature and become due and payable on (i) in the case of Loans, the Applicable Repayment Date for such Loan, and (ii) in the case of all other Obligations, the Termination Date. Each Borrower hereby promises to pay as and when due each Obligation owing by it. Each Borrower hereby waives demand, presentment, protest or notice of any kind with respect to each such Obligation.

Section 2.7 Prepayments. (a) Borrowers may prepay without premium or penalty and in whole or in part (but, if in part, then (i) in an amount not less than $5,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii) in an amount such that the minimum amount required for a Borrowing pursuant to Section 2.3 hereof remains outstanding) any Borrowing of Eurodollar Loans upon three (3) Business Days’ prior irrevocable notice to the Administrative Agent or, in the case of a Borrowing of Base Rate Loans, irrevocable notice delivered to the Administrative Agent no later than 12:00 noon (Chicago time) on the date of prepayment, such prepayment to be made by the payment of the principal amount to be prepaid and accrued interest thereon to the date fixed for prepayment. In the case of Eurodollar Loans, any amounts owing under Section 2.10 hereof as a result of such prepayment shall be paid contemporaneously with such prepayment. The Administrative Agent will promptly advise each Lender of any such prepayment notice it receives from a Borrower. Any amount paid or prepaid before the Termination Date may, subject to the terms and conditions of this Agreement, be borrowed, repaid and borrowed again.

(b) If the aggregate amount of outstanding Loans shall at any time for any reason exceed the Commitments then in effect, the Borrowers shall, immediately and without notice or demand, pay the amount of such excess to the Administrative Agent for the ratable benefit of the Lenders as a prepayment of the Loans and such prepayments shall not be subject to the provisions of Section 2.7(a). Immediately upon determining the need to make any such prepayment Borrowers shall notify the Administrative Agent of such required prepayment. Each such prepayment shall be accompanied by a payment of all accrued and unpaid interest on the Loans prepaid and shall be subject to Section 2.10.

Section 2.8 Default Rate. If any Obligation is not paid when due (whether by acceleration or otherwise), or upon the occurrence of any Event of Default and notice from the Administrative Agent to the Borrowers referencing such Event of Default and stating that the additional interest ("Default Interest") specified in this Section 2.8 shall commence accruing, all Obligations shall, to the extent permitted by applicable law, bear interest (computed on the basis of a year of 360 days and actual days elapsed or, if based on the rate described in clause (i) of the definition of Base Rate, on the basis of a year of 365 or 366 days, as applicable, and the actual number of days elapsed) from the date such payment on such Obligations was due or such notice was delivered, until paid in full or such Event of Default is waived in accordance with the provisions of this Agreement, payable on demand, at a rate per annum equal to:

(a) for any Obligation other than a Eurodollar Loan (including principal and interest relating to Base Rate Loans and interest on Eurodollar Loans), the sum of two percent (2%) plus the Applicable Margin applicable to Base Rate Loans plus the Base Rate from time to time in effect; and

(b) for the principal of any Eurodollar Loan, the sum of two percent (2%) plus the rate of interest in effect thereon at the time of such default until the end of the Interest Period applicable thereto and, thereafter, at a rate per annum equal to the sum of two percent (2%) plus the Applicable Margin applicable to Base Rate Loans plus the Base Rate from time to time in effect;

provided, however, that following acceleration of the Loans pursuant to Section 8.3, Default Interest shall accrue and be payable hereunder whether or not previously required by the Administrative Agent.

Section 2.9 Evidence of Debt. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of each Borrower to such Lender resulting from each Loan owing to such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder in respect of Loans. Each Borrower agrees that upon notice by any Lender to such Borrower (with a copy of such notice to the Administrative Agent) to the effect that a Note is required or appropriate in order for such Lender to evidence (whether for purposes of pledge, enforcement or otherwise) the Loans owing to, or to be made by, such Lender under the Credit Documents, such Borrower shall promptly execute and deliver to such Lender a promissory note in the form of Exhibit A hereto (each such promissory note is hereinafter referred to as a “Note” and collectively such promissory notes are referred to as the “Notes”).

(b) The Register maintained by the Administrative Agent pursuant to Section 11.8(c) shall include a control account, and a subsidiary account for each Lender, in which accounts (taken together) shall be recorded (i) the date and amount of each Borrowing made hereunder, the applicable Borrower for such Borrowing, the type of Loan comprising such Borrowing and, if appropriate, the Interest Period applicable thereto, (ii) the terms of each Assignment and Assumption delivered to and accepted by it, (iii) the amount of any principal or interest due and payable or to become due and payable from each Borrower to each Lender hereunder and (iv) the amount of any sum received by the Administrative Agent from a Borrower hereunder and each Lender’s share thereof.

(c) Entries made in good faith by the Administrative Agent in the Register pursuant to subsection (b) above, and by each Lender in its account or accounts pursuant to subsection (a) above, shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from a Borrower to, in the case of the Register, each Lender and, in the case of such account or accounts, such Lender, under this Agreement, absent manifest error; provided, however, that the failure of the Administrative Agent or such Lender to make an entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of a Borrower under this Agreement.

Section 2.10 Funding Indemnity. If any Lender shall incur any loss, cost or expense (including, without limitation, any loss, cost or expense (excluding loss of margin) incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Lender to fund or maintain any Eurodollar Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to such Lender) as a result of:

(a) any payment (whether by acceleration, pursuant to Section 9.5 or otherwise), prepayment or conversion of a Eurodollar Loan on a date other than the last day of its Interest Period,

(b) any failure (because of a failure to meet the conditions of Section 6 or otherwise) by a Borrower to borrow or continue a Eurodollar Loan, or to convert a Base Rate Loan into a Eurodollar Loan, on the date specified in a notice given pursuant to Section 2.4(a) or established pursuant to Section 2.4(c) hereof,

(c) any failure by a Borrower to make any payment or prepayment of principal on any Eurodollar Loan when due (whether by acceleration or otherwise),

(d) any acceleration of the maturity of a Eurodollar Loan as a result of the occurrence of any Event of Default hereunder, or

(e) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 9.5(b),

then, upon the demand of such Lender, the applicable Borrower shall pay to such Lender such amount as will reimburse such Lender for such loss, cost or expense. If any Lender makes such a claim for compensation, it shall provide to such Borrower, with a copy to the Administrative Agent, a certificate executed by an officer of such Lender setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) and the amounts shown on such certificate if reasonably calculated shall be prima facie evidence of the amount of such loss, cost or expense.

Section 2.11 Commitments. (a) Borrowers shall have the right at any time and from time to time, upon five (5) Business Days’ prior written notice to the Administrative Agent, to reduce or terminate the Commitments without premium or penalty, in whole or in part, any partial termination or reduction to be (i) in an amount not less than $5,000,000 and integral multiples of $1,000,000 in excess thereof, and (ii) allocated ratably among the Lenders in proportion to their respective Percentages; provided that the Commitments may not be reduced to an amount less than the amount of the Loans then outstanding. The Administrative Agent shall give prompt notice to each Lender of any reduction or termination of Commitments. Any reduction or termination of Commitments pursuant to this Section 2.11 may not be reinstated.

(b) The Borrowers and the Administrative Agent may from time to time add additional financial institutions as parties to this Agreement or, with the written consent of an existing Lender, increase the Commitment of such existing Lender (any such financial institution or existing Lender which is increasing its commitment being referred to as an “Added Lender”) pursuant to documentation satisfactory to the Borrowers and the Administrative Agent and any such Added Lender shall for all purposes be considered a Lender for purposes of this Agreement and the other Credit Documents with a Commitment as set forth in such documentation. Any such Added Lender shall on the date it is deemed a party to this Agreement purchase from the other Lenders its Percentage (or the increase in its Percentage, in the case of an Added Lender which is an existing Lender) of the Loans outstanding. Notwithstanding anything contained in

this Section 2.11(b) to the contrary but subject to Section 2.12, the aggregate amount of Commitments may not at any time exceed $600,000,000 without the consent of the Required Lenders.

Section 2.12 Increase in the Aggregate Commitments (a) The Borrowers may, at any time prior to the Termination Date but in any event not more than twice in any twelve month period, by notice to the Administrative Agent and in accordance with Section 2.12(b), request that the aggregate amount of the Commitments be increased by an amount of $25,000,000 or an integral multiple thereof (each a "Commitment Increase") to be effective as of a date that is at least 90 days prior to the scheduled Termination Date then in effect (the "Increase Date") as specified in the related notice to the Administrative Agent; provided, however that (i) in no event shall the aggregate amount of the Commitments at any time exceed $800,000,000, (ii) on the date of any request by the Borrowers for a Commitment Increase and on the related Increase Date the applicable conditions set forth in Sections 3.2(f) and 6.2 shall be satisfied and (iii) prior to the effectiveness of any such increase, the Borrowers shall deliver a certified copy of their Board of Directors' resolutions authorizing such increase.

(b) The Administrative Agent shall promptly notify the Lenders of a request by the Borrowers for a Commitment Increase, which notice shall include (i) the proposed amount of such requested Commitment Increase, (ii) the proposed Increase Date and (iii) the date by which Lenders wishing to participate in the Commitment Increase must commit to an increase in the amount of their respective Commitments (the "Commitment Date"). Each Lender that is willing to participate in such requested Commitment Increase (each an "Increasing Lender") shall, in its sole discretion, give written notice to the Administrative Agent on or prior to the Commitment Date of the amount by which it is willing to increase its Commitment. Failure of a Lender to provide any such notice shall be considered a rejection of an offer to increase its commitment. If the Lenders notify the Administrative Agent that they are willing to increase the amount of their respective Commitments by an aggregate amount that exceeds the amount of the requested Commitment Increase, the requested Commitment Increase shall be allocated among the Lenders willing to participate therein in such amounts as are agreed between the Borrowers and the Administrative Agent.

(c) Promptly following each Commitment Date, the Administrative Agent shall notify the Borrowers as to the amount, if any, by which the Lenders are willing to participate in the requested Commitment Increase. If the aggregate amount by which the Lenders are willing to participate in any requested Commitment Increase on any such Commitment Date is less than the requested Commitment Increase, then the Borrowers may extend offers to one or more Eligible Assignees to participate in any portion of the requested Commitment Increase that has not been committed to by the Lenders as of the applicable Commitment Date; provided, however, that the Commitment of each such Eligible Assignee shall be in an amount not less than $5,000,000.

(d) On each Increase Date, each Eligible Assignee that accepts an offer to participate in a Commitment Increase requested in accordance with Section 2.12(a) (each such Eligible Assignee, an "Assuming Lender") shall become a Lender party to this Agreement as of such Increase Date and the Commitment of each Increasing Lender for such requested Commitment Increase shall be increased by the amount of the Commitment Increase so requested (or by the

amount allocated to such Lender pursuant to the last sentence of Section 2.12(b)) as of such Increase Date. On each Increase Date, the Administrative Agent shall notify the Lenders (including, without limitation, each Assuming Lender) and the Borrowers, on or before 11:00 A.M. (Chicago time), by telecopier, of the occurrence of the Commitment Increase to be effected on such Increase Date and shall record in the Register the relevant information with respect to each Increasing Lender and each Assuming Lender on such date. Each Increasing Lender and each Assuming Lender shall, before 2:00 P.M. (Chicago time) on the Increase Date, make available for the account of its applicable lending office to the account of the Administrative Agent, in same day funds, in the case of such Assuming Lender, an amount equal to such Assuming Lender's ratable portion of the Borrowings then outstanding (calculated based on its Commitment as a percentage of the aggregate Commitments outstanding after giving effect to the relevant Commitment Increase) and, in the case of such Increasing Lender, an amount equal to the excess of (i) such Increasing Lender's ratable portion of the Borrowings then outstanding (calculated based on its Commitment as a percentage of the aggregate Commitments outstanding after giving effect to the relevant Commitment Increase) over (ii) such Increasing Lender's ratable portion of the Borrowings then outstanding (calculated based on its Commitment (without giving effect to the relevant Commitment Increase) as a percentage of the aggregate Commitments (without giving effect to the relevant Commitment Increase). After the Administrative Agent's receipt of such funds from each such Increasing Lender and each such Assuming Lender, the Administrative Agent will promptly thereafter cause to be distributed like funds to the other Lenders for the account of their respective applicable lending offices in an amount to each other Lender such that the aggregate amount of the outstanding Loans owing to each Lender after giving effect to such distribution equals such Lender's ratable portion of the Borrowings then outstanding (calculated based on its Commitment as a percentage of the aggregate Commitments outstanding after giving effect to the relevant Commitment Increase).

Section 2.13 Defaulting Lenders.

Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a) fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 3.1(a);

(b) the Commitment and Loans of such Defaulting Lender shall not be included in determining whether the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 11.9 other than those which require the consent of all Lenders or of each affected Lender);

(c) to the extent the Administrative Agent receives any payments or other amounts for the account of a Defaulting Lender under this Agreement such Defaulting Lender shall be deemed to have requested that the Administrative Agent use such payment or other amount to fulfill such Defaulting Lender's previously unsatisfied obligations to fund a Loan or Loans, unless such payment or other amounts is subject to a good faith dispute;

(d) no Lender shall be deemed to have consented to increase its Commitment pursuant to Section 2.12 unless that Lender shall have affirmatively given such consent in accordance with that Section, and no Lender shall be deemed to have agreed to an extension pursuant to Section 3.2 unless that Lender shall have affirmatively given its agreement in accordance with that Section; and

(e) for the avoidance of doubt, the Borrowers shall retain and reserve their other rights and remedies respecting each Defaulting Lender.

SECTION 3. FEES AND EXTENSIONS.

Section 3.1 Fees.

(a) Commitment Fee and other Fees. From and after the Closing Date, the Borrowers shall pay to the Administrative Agent for the ratable account of the Lenders in accordance with their Percentages a commitment fee accruing at a rate per annum equal to the Commitment Fee Rate on the average daily amount of the difference between the total Commitments (whether used or unused) and the principal balance of all Loans then outstanding. Such commitment fee is payable in arrears on the last Business Day of each calendar quarter and on the Termination Date, and if the Commitments are terminated in whole prior to the Termination Date, the fee for the period to but not including the date of such termination shall be paid in whole on the date of such termination. On the Closing Date, the Borrower shall pay to the Administrative Agent for the ratable account of the Lenders in accordance with their Percentages all other fees payable to the Lenders pursuant to the Fee Letters.

(b) Administrative Agent Fees. Nicor shall pay to the Joint Lead-Arrangers and the Administrative Agent for their sole account the fees agreed to by Nicor in the Fee Letters or as otherwise agreed among them in writing.

(c) Fee Calculations. All fees payable under this Agreement shall be payable in U.S. Dollars and shall be computed on the basis of a year of 360 days, for the actual number of days elapsed. All determinations of the amount of fees owing hereunder (and the components thereof) shall be made by the Administrative Agent and shall be prima facie evidence of the amount of such fee.

Section 3.2 Extensions.

(a) Requests for Extension. The Borrowers may, by notice to the Administrative Agent (which shall promptly notify the Lenders) not earlier than 45 days and not later than 35 days prior to each anniversary of the Closing Date (the “Annual Anniversary”), request that each Lender extend such Lender’s Termination Date for an additional year from the Termination Date then in effect hereunder (the “Existing Termination Date”).

(b) Lender Elections to Extend. Each Lender, acting in its sole and individual discretion, shall, by notice to the Administrative Agent given not earlier than 30 days prior to the Annual Anniversary and not later than the date (the “Notice Date”) that is 20 days prior to the Annual Anniversary, advise the Administrative Agent whether or not such Lender agrees to such extension and each Lender that determines not to so extend its Commitment Termination Date (a

“Non-Extending Lender”) shall notify the Administrative Agent of such fact promptly after such determination (but in any event no later than the Notice Date) and any Lender that does not so advise the Administrative Agent on or before the Notice Date shall be deemed to be a Non-Extending Lender. The election of any Lender to agree to such extension shall not obligate any other Lender to so agree.

(c) Notification by Administrative Agent. The Administrative Agent shall notify the Borrowers of each Lender’s determination under this Section no later than the date 15 days prior to the Annual Anniversary (or, if such date is not a Business Day, on the next preceding Business Day).

(d) Additional Commitment Lenders. The Borrowers shall have the right on or before the Annual Anniversary to replace each Non-Extending Lender with, and add as “Lenders” under this Agreement in place thereof, one or more Eligible Assignees (each, an “Additional Commitment Lender”) with the approval of the Administrative Agent (which approval shall not be unreasonably withheld). Each Additional Commitment Lender shall enter into an agreement in form and substance satisfactory to the Borrowers and the Administrative Agent pursuant to which such Additional Commitment Lender shall, effective as of the Existing Termination Date, undertake a Commitment (and, if any such Additional Commitment Lender is already a Lender, its Commitment shall be in addition to such Lender’s Commitment hereunder on such date).

(e) Minimum Extension Requirement. If (and only if) the Required Lenders have agreed to extend their Termination Date, then, effective as of the Annual Anniversary, the Termination Date of each Extending Lender and of each Additional Commitment Lender shall be extended to the date falling one year after the Existing Termination Date (except that, if such date is not a Business Day, such Commitment Date as so extended shall be the next preceding Business Day) and each Additional Commitment Lender shall thereupon become a “Lender” for all purposes of this Agreement.

(f) Conditions to Effectiveness of Extensions. Notwithstanding the foregoing, the extension of the Termination Date pursuant to this Section shall not be effective with respect to any Lender unless:

(i) no Default or Event of Default shall have occurred and be continuing on the date of such extension and after giving effect thereto;

(ii) the representations and warranties contained in this Agreement are true and correct on and as of the date of such extension and after giving effect thereto, as though made on and as of such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date); and

(iv) on or before the Termination Date of each Non-Extending Lender, (1) the Borrowers shall have paid in full the principal of and interest on all of the Loans made by such Non-Extending Lender to the Borrowers hereunder and (2) the Borrowers shall have paid in full all other Obligations owing to such Lender hereunder.

SECTION 4. PLACE AND APPLICATION OF PAYMENTS.

All payments of principal of and interest on the Loan, and all other Obligations payable by the Borrowers under the Credit Documents shall be made by Borrowers in U.S. Dollars to the Administrative Agent by no later than 1:00 p.m. (Chicago time) on the due date thereof at the principal office of the Administrative Agent in New York, New York pursuant to the payment instructions set forth on Part A of Schedule 4 hereof (or such other location in the United States as the Administrative Agent may designate to Borrowers) for the benefit of the Person or Persons entitled thereto. Any payments received after such time shall be deemed to have been received by the Administrative Agent on the next Business Day. All such payments shall be made free and clear of, and without deduction for, any set-off, defense, counterclaim, levy, or any other deduction of any kind in immediately available funds at the place of payment. The Administrative Agent, will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest on Loans or applicable fees ratably to the Lenders and like funds relating to the payment of any other amount payable to any Person to such Person, in each case to be applied in accordance with the terms of this Agreement.

Such Borrower is (i) duly organized and existing in good standing under the laws of the State of Illinois; (ii) has all necessary corporate power to carry on its present business; and (iii) is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the Property owned or leased by it makes such licensing, qualification or good standing necessary and in which the failure to be so licensed, qualified or in good standing would have a Material Adverse Effect.

Section 5.2 Subsidiaries. Schedule 5.2 (as updated from time to time pursuant to Section 7.1) hereto identifies each Material Subsidiary which is not also a Borrower, such Material Subsidiary’s jurisdiction of incorporation or formation, the percentage of issued and outstanding shares of each class of such Material Subsidiary’s capital stock or other equity interests owned by a Borrower and/or such Borrower’s Subsidiaries and, if such percentage is not one hundred percent (100%) (excluding directors’ qualifying shares as required by law), a description of each class of its authorized capital stock and the number of shares or equity interests of each class issued and outstanding. Each Material Subsidiary is duly organized and existing in good standing under the laws of the jurisdiction of its organization, has all necessary organizational power to carry on its present business, and is duly licensed or qualified and in good standing in each jurisdiction in which the nature of the business transacted by it or the nature of the Property owned or leased by it makes such licensing or qualification necessary and in which the failure to be so licensed or qualified would have a Material Adverse Effect. All of the issued and outstanding shares of capital stock or other equity interests, as applicable, of each Material Subsidiary owned directly or indirectly by the Borrowers are validly issued and outstanding and fully paid and nonassessable. All such shares and other equity interests owned by a Borrower are owned beneficially, and of record, free of any Lien, except as permitted in Section 7.9.

(b) There are no labor controversies pending or, to the best knowledge of Borrowers, threatened against a Borrower or any Subsidiary of a Borrower which could (individually or in the aggregate) have a Material Adverse Effect.

Section 5.7 Approvals. No material authorization, consent, approval, license, exemption, filing or registration with any court or Governmental Authority, nor any approval or consent of the stockholders of a Borrower or any Subsidiary of a Borrower or any material

approval, consent or authorization from any other Person, is necessary to the valid execution, delivery or performance by a Borrower or any Subsidiary of a Borrower of any Credit Document to which it is a party, except for such authorizations, consents, approvals, licenses, exemptions, filings or registrations which have been made or obtained.

Section 5.8 ERISA. During the twelve consecutive-month period prior to the date of the execution and delivery of this Agreement and prior to the date of any Borrowing, no steps have been taken to terminate or completely or partially withdraw from any Pension Plan, and no contribution failure has occurred with respect to any Pension Plan sufficient to give rise to a Lien under section 302 (f) of ERISA.

Board Regulation U or X or any regulations substituted therefor, as from time to time in effect, are used in this Section 5.10 with such meanings. The proceeds of the Loans are to be used solely to provide back-up for commercial paper, the proceeds of which will be used or have been used to purchase natural gas, and other general corporate purposes of a Borrower.

Section 5.12 Ownership of Property; Liens. Each Borrower and each Subsidiary of such Borrower owns good title to, or a valid leasehold interest in, or other enforceable interest in, its Property to the extent owned or leased by it (except where the failure to have such title, a valid leasehold interest or other enforceable interest is not reasonably likely to have a Material Adverse Effect) free and clear of all Liens, except as permitted in Section 7.9.

Section 5.13 Compliance with Agreements.

shall be limited to the Property of the Borrowers or any of their Material Subsidiaries which was subject to the Lien so extended, renewed or replaced;

(f) Liens securing Indebtedness and other obligations; provided that such Liens permitted by this paragraph (f) shall only be permitted to the extent the aggregate amount of Indebtedness and other obligations secured by all such Liens does not exceed ten percent (10%) of the difference between (A) Consolidated Assets as reflected on the most recent balance sheet delivered by Nicor pursuant to Section 7.6, minus (B) the amount of Indebtedness then outstanding under the Nicor Gas Indenture;

(i) (i) a Borrower or any other member of the Controlled Group shall fail to pay to the PBGC or any Pension Plan any amount or amounts aggregating in excess of $20,000,000 when due, which if remain unpaid could reasonably result in a Lien against Borrowers, (ii) a notice of intent to terminate a Pension Plan or Pension Plans at a single time having aggregate Unfunded Vested Liabilities in excess of $20,000,000 (collectively, a “Material Plan”) shall be filed by the sponsor of such Pension Plan and it could reasonably be expected that a Borrower shall have liability for any Unfunded Vested Liabilities in excess of $20,000,000 or (iii) the PBGC shall institute proceedings

to terminate or cause a trustee to be appointed to administer any Material Plan and it reasonably could be expected to result in liability to the Borrowers in excess of $20,000,000;

(j) a Borrower or any Subsidiary of a Borrower or any Person acting on behalf of a Borrower, a Subsidiary or any governmental authority challenges the validity of this Agreement, the Fee Letters or the Notes or a Borrower’s or one of its Subsidiary’s obligations thereunder;

(k) a Change of Control Event shall have occurred; or

(l) a Borrower shall for any reason cease to be wholly liable for the full amount of the Obligations owing by it.

Section 8.2 Non-Bankruptcy Defaults. When any Event of Default other than those described in subsections (f) or (g) of Section 8.1 hereof has occurred and is continuing, the Administrative Agent shall, if so directed by the Required Lenders, by written notice to Borrowers: (a) terminate the remaining Commitments and all other obligations of the Lenders hereunder on the date stated in such notice (which may be the date thereof); and (b) declare the principal of and the accrued interest on all outstanding Loans to be forthwith due and payable and thereupon all outstanding Loans, including both principal and interest thereon, and all other Obligations, shall be and become immediately due and payable together with all other amounts payable under the Credit Documents without further demand, presentment, protest or notice of any kind, all of which are hereby waived by each Borrower. The Administrative Agent, after giving notice to Borrowers pursuant to Section 8.1(c) or this Section 8.2, shall also promptly send a copy of such notice to the other Lenders, but the failure to do so shall not impair or annul the effect of such notice.

Section 8.3 Bankruptcy Defaults. When any Event of Default described in subsections (f) or (g) of Section 8.1 hereof has occurred and is continuing, then all outstanding Loans, including both interest and principal thereon, and all other Obligations shall immediately become due and payable together with all other amounts payable under the Credit Documents without presentment, demand, protest or notice of any kind, the obligation of the Lenders to extend further credit pursuant to any of the terms hereof shall immediately terminate.

SECTION 9. CHANGE IN CIRCUMSTANCES; TAXES.

Section 9.1 Change of Law. Notwithstanding any other provisions of this Agreement or any Note, if at any time after the date hereof any change in applicable law or regulation or in the interpretation thereof makes it unlawful for any Lender to make or continue to maintain Eurodollar Loans or to perform its obligations as contemplated hereby, such Lender shall promptly give notice thereof to the Borrowers and such Lender’s obligations to make or maintain Eurodollar Loans under this Agreement shall terminate until it is no longer unlawful for such Lender to make or maintain Eurodollar Loans. The applicable Borrower shall convert the outstanding principal amount of any such affected Eurodollar Loans of such Lender into a Base Rate Loan and on the date of such conversion pay to such Lender all interest accrued thereon at a rate per annum equal to the interest rate applicable to such Eurodollar Loan. Thereafter, subject

to all of the terms and conditions of this Agreement, such Borrower may then elect to borrow the principal amount of any Eurodollar Loans from such Lender by means of Base Rate Loans from such Lender, which Base Rate Loans shall not be made ratably by the Lenders but only from such affected Lender.

Section 9.2 Unavailability of Deposits or Inability to Ascertain, or Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for any Borrowing of Eurodollar Loans:

(a) the Administrative Agent determines that deposits in U.S. Dollars (in the applicable amounts) are not being offered to major banks in the eurodollar interbank market for such Interest Period, or that by reason of circumstances affecting the interbank eurodollar market adequate and reasonable means do not exist for ascertaining the applicable LIBOR, or

(b) Lenders having more than 33% percent of the aggregate amount of the Commitments reasonably determine and so advise the Administrative Agent that LIBOR as reasonably determined by the Administrative Agent will not adequately and fairly reflect the cost to such Lenders or Lender of funding their or its Eurodollar Loans or Loan for such Interest Period,

then the Administrative Agent shall forthwith give notice thereof to the Borrowers and the Lenders, whereupon until the Administrative Agent notifies the Borrowers that the circumstances giving rise to such suspension no longer exist, the obligations of the Lenders or of the relevant Lender to make Eurodollar Loans shall be suspended.

Section 9.3 Increased Costs.

(a) Increased Costs Generally. If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any reserve requirement reflected in Adjusted LIBOR);

(ii) subject any Lender to any tax of any kind whatsoever with respect to this Agreement or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 9.4 and any changes relating to any Excluded Tax payable by such Lender); or

(iii) impose on any Lender any other condition, cost or expense affecting this Agreement or Eurodollar Loans made by such Lender hereunder;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan), or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or any other amount), then upon request of such Lender the Borrowers will pay

to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender determines that any Change in Law affecting such Lender or any lending office of such Lender or such Lender’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, such Lender to a level below that which such Lender or such Lender’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time the Borrowers will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its holding company as specified in paragraph (a) or (b) of this Section and delivered to the Borrowers shall be prima facie evidence of such costs absent manifest error. The Borrowers shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section 9.3 shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrowers shall not be required to compensate a Lender pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof).

Section 9.4 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrowers hereunder or under any other Credit Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes or Other Taxes; provided that if a Borrower shall be required by applicable law to deduct any Indemnified Taxes (including any Other Taxes) from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions and (iii) such Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) Payment of Other Taxes by the Borrowers. Without limiting the provisions of paragraph (a) above, the applicable Borrower shall timely pay any Other Taxes to the relevant Governmental Authority related to its obligations under this Agreement in accordance with applicable law.

(c) Indemnification by the Borrowers. Each Borrower severally shall indemnify the Administrative Agent and each Lender within 10 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) arising in connection with payments made by such Borrower hereunder or under any other Credit Document paid by the Administrative Agent or such Lender and any penalties, interest and reasonable expenses arising therefrom or with respect thereto except to the extent that such penalties, interest and expenses are attributable to the gross negligence or willful misconduct of the Administrative Agent or such Lender. A certificate as to the amount of such payment or liability delivered to the applicable Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) Evidence of Payments. Upon the request of the Administrative Agent and as soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Borrower to a Governmental Authority, such Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under any Credit Document under the law of the jurisdiction in which a Borrower is incorporated or otherwise organized or any treaty to which such jurisdiction is a party (in each case such jurisdiction will include the United States if a Borrower is incorporated or organized in any state thereof or the District of Columbia), shall deliver to the Borrowers (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by a Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate of withholding.

Each Lender and Administrative Agent that is a United States person as defined in Section 7701(a)(30) of the Code (each a “U.S. Lender”) shall provide prior to or on the Closing Date (or on or prior to the date it becomes a party to this Agreement) to Borrower and, if applicable, the Administrative Agent, a properly completed and executed IRS Form W-9 (certifying that such U.S. Lender is entitled to an exemption from United States backup withholding tax) or any successor form. Solely for purposes of this Section 9.4(e), a U.S. Lender shall not include a Lender or Administrative Agent that may be treated as an exempt recipient based on the indicators described in Treasury Regulation Section 1.6049-4(c)(1)(ii). In addition, any Lender, if requested by a Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by a Borrower or the Administrative Agent as will enable such Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements.

Without limiting the generality of the foregoing, in the event that a Borrower is incorporated or otherwise organized in the United States of America or any state thereof or the District of Columbia, any Foreign Lender shall deliver to such Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on

which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of a Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so) the following documents, as applicable:

(i) Duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States of America is a party,

(ii) duly completed copies of Internal Revenue Service Form W-8ECI,

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of any Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

(iv) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit the Borrowers to determine the withholding or deduction required to be made.

(f) Treatment of Certain Refunds. If the Administrative Agent or a Lender determines, in its reasonable discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by a Borrower or with respect to which a Borrower has paid additional amounts pursuant to this Section 9.4(f), it shall pay to such Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by a Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that a Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to a Borrower or any other Person.

(g) Tax Benefit. If and to the extent that any Lender is able, in its sole opinion, to apply or otherwise take advantage of any offsetting tax credit or other similar tax benefit arising out of or in conjunction with any deduction or withholding which gives rise to an obligation on the Borrower to pay any Indemnified Taxes or Other Taxes pursuant to this Section 9.4, then such Lender shall, to the extent that in its sole opinion it can do so without prejudice to the retention of the amount of such credit or benefit and without any other adverse tax consequences for such Lender, reimburse to the Borrower at such time as such tax credit or benefit shall have

actually been received by such Lender such amount as such Lender shall, in its sole opinion, have determined to be attributable to the relevant deduction or withholding and as will leave such Lender in no better or worse position than it would have been in if the payment of such Indemnified Taxes or Other Taxes had not been required. Nothing in this Section 9.4 shall oblige any Lender to disclose to the Borrower or any other person any information regarding its tax affairs or tax computations.

Section 9.5 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 9.3, or requires a Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 9.4, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 9.3 or 9.4, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be materially disadvantageous to such Lender.

(b) Replacement of Lenders. If (i) any Lender requests compensation under Section 9.3, (ii) or if a Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 9.4, or (iii) if any Lender becomes a Defaulting Lender, then the Borrowers may, at their expense and effort or, in the case of an assignment from a Defaulting Lender, at the expense of such Defaulting Lender, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.8), all of its interests, rights and obligations under this Agreement and the related Credit Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(i) the Borrowers shall have paid to the Administrative Agent the assignment fee specified in Section 11.8,

(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents (including any amounts under Section 2.10) 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),

(iii) in the case of any such assignment resulting from a claim for compensation under Section 9.3 or payments required to be made pursuant to Section 9.4, such assignment will result in a reduction in such compensation or payments thereafter, and

(iv) such assignment does not conflict with applicable law.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrowers to require such assignment and delegation cease to apply.

In the event that a replaced Lender does not execute an Assignment and Assumption pursuant to Section 11.8 within five (5) Business Days after receipt by such replaced Lender of notice of replacement pursuant to this Section 9.5(b) and presentation to such replaced Lender of an Assignment and Assumption evidencing an assignment pursuant to this Section 9.5(b), the Borrowers shall be entitled (but not obligated) to execute such an Assignment and Assumption on behalf of such replaced Lender, and any such Assignment and Assumption so executed by the Borrowers, the assignee and the Agent shall be effective for purposes of this Section 9.5(b) and Section 11.8.

Section 9.6 Discretion of Lender as to Manner of Funding. Notwithstanding any other provision of this Agreement, each Lender shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit; it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Lender had actually funded and maintained each Eurodollar Loan through the purchase of deposits in the eurodollar interbank market having a maturity corresponding to such Loan’s Interest Period and bearing an interest rate equal to LIBOR for such Interest Period.

SECTION 10. THE AGENT.

Section 10.1 Appointment and Authority. Each of the Lenders hereby irrevocably appoints JPMorgan Chase Bank, N.A. as its agent hereunder and under the other Credit Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Section 10 are solely for the benefit of the Administrative Agent and the Lenders, and neither Borrower shall have rights as a third party beneficiary of any of such provisions.

Section 10.2 Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrowers or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 10.3 Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Credit Documents. Without limiting the generality of the foregoing, the Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has occurred and is continuing,

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Credit Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the relevant Lenders as shall be expressly provided for under the circumstances as provided in this Agreement); provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Credit Document or applicable law. In all cases in which this Agreement and the other Credit Documents do not require the Administrative Agent to take certain actions, the Administrative Agent shall be fully justified in using its reasonable discretion in failing to take or in taking any action hereunder and thereunder, and

(c) shall not, except as expressly set forth herein and in the other Credit Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to either Borrower or any of its Affiliates that is communicated to or obtained by the person serving as the Administrative Agent or any of its Affiliates in any capacity.

The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for under the circumstances as provided in this Agreement) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice thereof is given in writing to the Administrative Agent by a Borrower or a Lender.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Credit Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) 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 Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Credit Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in this Agreement, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

Section 10.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Administrative Agent may presume that such condition is

satisfactory to such Lender unless the Administrative Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrowers), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 10.5 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative 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 Related Parties of the Administrative 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 Administrative Agent.

Section 10.6 Resignation of Administrative Agent. The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrowers. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrowers (and so long as no Event of Default shall have occurred and be continuing, with the consent of the Borrower), to appoint a successor, which shall be a bank with an office in Chicago, Illinois or New York, New York, or an Affiliate of any such bank with an office in Chicago, Illinois, or New York, New York. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders appoint a successor Administrative Agent meeting the qualifications set forth above; provided that if the Administrative Agent shall notify the Borrowers and the Lenders that no such successor is willing to accept such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Credit Documents and (2) all payments, communications and determinations to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder and under the other Credit Documents (if not already discharged therefrom as provided above in this paragraph). The fees payable by the Borrowers to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed among the Borrowers and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Credit Documents, the provisions of this Section 10.6 and Section 11.11 shall continue in effect for the benefit of such retiring Administrative 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 Administrative Agent was acting as Administrative Agent.

Section 10.7 Non-Reliance on Administrative Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such 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 Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Credit Document or any related agreement or any document furnished hereunder or thereunder.

Section 10.8 No Other Duties, etc. Anything herein to the contrary notwithstanding, no Syndication Agent, Documentation Agent, Bookrunner nor Joint Lead-Arranger listed on the cover page hereof shall have any powers, duties or responsibilities in such capacity under this Agreement or any of the other Credit Documents.

SECTION 11. MISCELLANEOUS.

Section 11.1 No Waiver of Rights. No delay or failure on the part of the Administrative Agent or any Lender or on the part of the holder or holders of any Note in the exercise of any power or right under any Credit Document shall operate as a waiver thereof, nor as an acquiescence in any default, nor shall any single or partial exercise thereof preclude any other or further exercise of any other power or right. The rights and remedies hereunder of the Administrative Agent, the Lenders and the holder or holders of any Notes are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise have.

Section 11.2 Non-Business Day. Except as otherwise expressly provided in this Agreement, if any payment of principal or interest on any Loan or of any other Obligation shall fall due on a day which is not a Business Day, interest or fees (as applicable) at the rate, if any, such Loan or other Obligation bears for the period prior to maturity shall continue to accrue on such Obligation from the stated due date thereof to and including the next succeeding Business Day, on which the same shall be payable.

Section 11.3 Survival of Representations. All representations and warranties made herein or in certificates given pursuant hereto shall survive the execution and delivery of this Agreement and the other Credit Documents, and shall continue in full force and effect with respect to the date as of which they were made as long as any credit is in use or available hereunder.

Section 11.4 Survival of Indemnities. All indemnities and all other provisions relating to reimbursement of the Lenders of amounts sufficient to protect the yield of the Lenders with respect to the Loans, including, but not limited to, Section 2.10, Section 9.3, Section 9.4 and Section 11.11 hereof, shall survive the termination of this Agreement and the other Credit Documents and the payment of the Loans and all other Obligations.

Section 11.5 Set-Off; Sharing of Payments. (a) Without limitation of any other rights of the Lenders, if an Event of Default shall have occurred and be continuing, each Lender and each of their respective Affiliates is hereby authorized at any time and from time to time, to the

fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender or any such Affiliate to or for the credit or the account of a Borrower against any and all of the obligations of the Borrowers now or hereafter existing under this Agreement or any other Credit Document to such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Credit Document and although such obligations of a Borrower may be contingent or unmatured or are owed to a branch or office of such Lender different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender or their respective Affiliates may have. Each Lender agrees promptly to notify the Borrowers and the Administrative Agent after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such setoff and application.

(b) If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its Percentage thereof as provided herein, then the Lender receiving such greater proportion shall notify the Administrative Agent of such fact and purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that all such payments shall be shared by the Lenders ratably in accordance with their Percentages and other amounts owing them; provided that:

(i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and

(ii) the provisions of this paragraph shall not be construed to apply to (x) any payment made by a Borrower pursuant to and in accordance with the express terms of this Agreement or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to a Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).

Each Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against such Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

Section 11.6 Notices.

(a) Notices Generally. Except in the case of notices and other communications expressly permitted to be given by telephone or email (and except as provided in paragraph (b) below), all notices and other communications provided for herein shall be in writing and shall be

Section 11.7 Counterparts; Integration; Effectiveness; Electronic Execution.

(a) Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 6.1, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic means shall be effective as delivery of a manually executed counterpart of this Agreement.

(b) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based record keeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

Section 11.8 Successors and Assigns.

(a) Successors and Assigns Generally. 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 neither Borrower may assign or otherwise transfer any of its rights or obligations hereunder (Except as permitted under Section 7.11 hereof), without the prior written consent of each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible 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 Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that

(i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loan of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000 (and the remaining aggregate amount of the Commitment of such assigning Lender shall not be less than $5,000,000 after giving effect to such assignment), unless each of the Administrative Agent and, so long as no Default or Event of Default has occurred and is continuing, the Borrowers otherwise consent (each such consent not to be unreasonably withheld or delayed);

(ii) 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 Loan or the Commitment assigned; and

(iii) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

Notwithstanding anything to the contrary in this Section 11.8(b), a Lender may not assign its Commitment and/or the Loans owing to it to any Competitor except during the occurrence and continuation of an Event of Default.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, 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 Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption 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 9.3 and 9.4 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) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrowers, shall maintain at one of its offices in Chicago, Illinois a copy of each Assignment and Assumption 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 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 Borrowers, the Administrative 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 Borrowers and any Lender at any reasonable time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrowers or the Administrative Agent, sell participations to any Person (other than a natural person or a Borrower or any of the Borrowers’ 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 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 Borrowers, the Administrative 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. Notwithstanding anything to the contrary in this Section 11.8(d), a Lender may not sell participations in its Commitment and/or the Loans owing to it to any Competitor except during the occurrence and continuation of an Event of Default.

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 of the type described in Section 11.9(i) that affects such Participant. Subject to paragraph (e) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Sections 9.3 and 9.4 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. Each Lender granting a participation under this Section 11.8(d) shall keep a register, meeting the requirements of Treasury Regulation Section 5f.103-1(c), of each participant, specifying such participant’s entitlement to payments of principal and interest with respect to such participation.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 9.3 and 9.4 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 Borrowers’ 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 9.4 unless the Borrowers are notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 9.4 as though it were a Lender.

(f) Certain Pledges. 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 without limitation 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.

(g) Certain Funding Arrangements. Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Bank”) may grant to a special purpose funding vehicle which is an Affiliate of such Bank (a “SPC”) and identified as such in writing by the Granting Bank to the Administrative Agent and the Borrowers, the option to provide to the Borrowers all or any part of any Loan that such Granting Bank would otherwise be obligated to make to the Borrowers pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Bank shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Bank to the same extent, and as if, such Loan were made by such Granting Bank. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Bank). 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. In addition, notwithstanding anything to the contrary contained in this Section 11.8(g), any SPC may (i) with notice to, but without the prior written consent of, the Borrowers and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Bank or to any financial institutions (consented to by the Borrowers and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This section may not be amended without the written consent of the SPC.

Section 11.9 Amendments. Any provision of the Credit Documents may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by (a) the Borrowers, (b) the Required Lenders, and (c) if the rights or duties of the Administrative Agent are affected thereby, the Administrative Agent; provided that:

(i) no amendment or waiver pursuant to this Section 11.9 shall (A) increase, decrease or extend any Commitment of any Lender without the consent of such Lender or (B) require payments of principal or interest on the Loan received by the Administrative

Agent to be made to the Lenders in a manner other than pro-rata in accordance with each Lender’s then outstanding Loans without the consent of each Lender or (C) reduce the amount of or postpone any fixed date for payment of any principal of or interest on any Loan or of any fee or other Obligation payable hereunder without the consent of each Lender; provided that the Required Lenders may waive any default interest accruing pursuant to Section 2.8 hereof; and

(ii) no amendment or waiver pursuant to this Section 11.9 shall, unless signed by each Lender, change this Section 11.9, or the definition of Required Lenders, or affect the number of Lenders required to take any action under the Credit Documents.

(b) Indemnification by Nicor. Nicor shall indemnify the Administrative Agent (and any sub-agent thereof) and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and expenses, including the fees, charges and disbursements of any counsel for any Indemnitee incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Credit Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the transactions contemplated hereby or thereby (including any relating to a misrepresentation by a Borrower under any Credit Document), (ii) any Loan or the use of the proceeds therefrom, (iii) any actual or alleged presence or Release of Hazardous Materials on or from any Property owned or operated by Nicor or any of its Subsidiaries, or any Environmental Liability related in any way to Nicor or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on

(c) Reimbursement by Lenders. To the extent that the Borrowers fail for any reason to pay within the time set forth in paragraph (e) below any amount required under paragraph (a) or (b) of this Section 11.11 to be paid to the Administrative Agent (or any sub-agent thereof) or any Related Party of the Administrative Agent, each Lender severally agrees to pay to the Administrative Agent (or any such sub-agent) or such Related Party, as the case may be, upon demand such Lender’s Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent (or any such sub-agent) or against any Related Party of the Administrative Agent acting for the Administrative Agent (or any such sub-agent) in connection with such capacity.

Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

Any Person required to maintain the confidentiality of Information as provided in this Section 11.15 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Notwithstanding anything herein to the contrary, “Information” shall not include, and the Administrative Agent and each Lender may disclose to any and all persons any information with respect to the U.S. federal income tax treatment and U.S. federal income tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or such Lender relating to such tax treatment and tax structure.

Each change in a rating shall be effective as of the date it is announced by the applicable rating agency.

With respect to either Borrower, if only two of (i) the Fitch Ratings, (ii) the S&P Rating and (iii) the Moody’s Rating (each, a “Debt Rating”) are assigned to either Borrower, and the Debt Ratings differ by one level, the applicable rating will be the higher of the Debt Ratings for such Borrower. If there are only two Debt Ratings for a Borrower, and a Borrower is split-rated and the ratings differential is two levels or more, the Debt Rating one level below the highest level will apply for such Borrower. If there are two Debt Ratings on the same level and the third Debt Rating differs, then the third Debt Rating will be disregarded and the level with two Debt Ratings will apply. If all three Debt Ratings differ, then the Debt Rating one level below the highest Debt Rating will apply. If at any time either Borrower does not have any Debt Rating, the “Equal to or lower than BBB/Baa2/BBB” level will apply for such Borrower; provided, however, that in such event such Borrower may propose an alternative rating agency or mechanism in replacement thereof, subject to the written consent of the Required Lenders.
