      Agent"),
      and
      certain of the lenders constituting the Required Lenders (as defined in the
      5-Year Credit Agreement, defined below).

     

    The
      Borrowers, the Administrative Agent and, among others, the financial
      institutions party thereto (the "Lenders"),
      are
      parties to the 5 year credit agreement dated as of September 13, 2005 (as
      modified and supplemented and in effect from time to time, the "5-Year
      Credit Agreement"),
      providing, subject to the terms and conditions thereof, several commitments
      of
      the Lenders to make available a revolving letter of credit facility for loans
      to
      the Borrowers in an aggregate principal or face amount of
      $600,000,000.

     

    The
      Borrowers, the Administrative Agent and the Lenders party to the 5-Year Credit

      Agreement are used herein (and in the introductions and recitals hereto) as
      defined therein.

     

    Section
      2.  Amendments.
      Subject
      to the satisfaction of the conditions precedent specified in Section
      4

      classification of any item in such financial statement and which would require
      an adjustment to such item the effect of which would be to cause the Borrowers

      interest or an easement, right-of-way, license or similar right of use or
      occupancy with respect to such Property or asset and (B) such Person has not
      assumed or become liable for the payment of such indebtedness; (v) all
      Guarantees issued by such Person of Indebtedness of another Person; (vi) all

      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); 

     

    (iii)
       the
      Borrowers shall deliver a certified copy of their respective Board of Directors'
      resolutions authorizing such extension; 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."

      warranties set forth in Section
      5
      of the
      5-Year Credit Agreement are true and complete on the date hereof as if made
      on
      and as of the date hereof (or, if any such representation or warranty is
      expressly stated to have been made as of a specific date, such representation
      or
      warranty shall be true and correct as of such specific date), and as if each
      reference in said Section

      of
      Default has occurred and is continuing.

     

    Section
      4.  Conditions
      Precedent.
      The
      amendments set forth in Section

      addressed to the Administrative Agent and the Lenders and (ii) counterparts
      of
      this Amendment executed by each Borrower, the Required Lenders and the
      Administrative Agent.

     

    Section
      5.  Waiver.
      The
      Required Lenders hereby waive all Defaults and Events of Default, if any, which
      may have occurred prior to the date of this Amendment resulting from (i) a
      failure by either Borrower to deliver documents to the Administrative Agent
      or
      the Lenders in accordance with Section 7.6 of the 5-Year Credit Agreement as
      in
      effect prior to this Amendment, (ii) any condition that existed or action or
      inaction by either Borrower that was not or may not have been in compliance
      with
      Sections 7.9, 7.13(e), 7.14(b), 7.17(b) or 7.18 of the 5-Year Credit Agreement
      as in effect prior to this Amendment, but would have been in compliance with
      the
      5-Year Credit Agreement as in effect on or after the date hereof, (iii) any
      inaccuracy in any representation or warranty made by either Borrower prior
      to
      this Amendment as to its compliance with Sections 7.6, 7.9, 7.13(e), 7.14(b),
      7.17(b) or 7.18 of the 5-Year Credit Agreement as in effect prior to this
      Amendment, (iv) any inaccuracy in the representation and warranty set forth
      in
      Section 5.12 of the 5-Year Credit Agreement as in effect prior to this Amendment
      or (v) a failure by either Borrower to provide notice of any such failure,
      condition, action, inaction or inaccuracy referred to in clauses (i) - (iv)
      above.

     

    Section
      6.  Miscellaneous.
      Except
      as herein provided, the 5-Year Credit Agreement shall remain unchanged and
      in
      full force and effect. This Amendment may be executed in any number of
      counterparts, all of which taken together shall constitute one and the same
      amendatory instrument and any of the parties hereto may execute this Amendment
      by signing any such counterpart. Delivery of an executed counterpart of a
      signature page of this Amendment by facsimile (or other electronic transmission)
      shall be effective as delivery of a manually executed counterparty hereof.
      This
      Amendment shall be governed by, and construed in accordance with, the law of
      the
      State of New York, United States of America, without giving effect to principles
      of conflicts of laws (other than Section 5-1401 of the New York General
      Obligations Law).

    COMPLIANCE
      CERTIFICATE

     

    COMPLIANCE
      CERTIFICATE

     

    This
      Compliance Certificate is furnished to JPMorgan Chase Bank, N.A., as
      Administrative Agent pursuant to the Credit Agreement dated as of September
      13,
      2005, among Northern Illinois Gas Company, an Illinois corporation
      (“Nicor
      Gas”),
      and
      Nicor Inc., an Illinois corporation (“Nicor”;
      Nicor
      Gas and Nicor are each referred to herein as a "Borrower"
      and
      collectively as "Borrowers")
      JPMorgan Chase Bank, N.A., as Administrative Agent and the financial
      institutions party thereto (as amended, supplemented or otherwise modified
      from
      time to time, the “Credit
      Agreement”).
      Unless otherwise defined herein, the terms used in this Compliance Certificate
      have the meanings ascribed thereto in the Credit Agreement.

     

    THE
      UNDERSIGNED HEREBY CERTIFIES THAT:

     

    1. I
      am the
      duly elected or appointed ___________________of Nicor;

     

    2. I
      have
      reviewed the terms of the Credit Agreement and I have made, or have caused
      to be
      made under my supervision, a detailed review of the transactions and conditions
      of Nicor and its Subsidiaries during the accounting period covered by the
      financial statements (which financial statements have been posted on Nicor's
      website on the Internet at www.nicor.com);

     

    3. The
      examinations described in paragraph 2 did not disclose, and I have no knowledge
      of, the existence of any condition or event which constitutes a Default or
      an
      Event of Default during or at the end of the accounting period covered by the
      Borrowers' financial statements for the year/quarter end (which financial
      statements have been posted on Nicor's website on the Internet at www.nicor.com)
      or as of the date of this Certificate, except as set forth below;
      and

     

    4. Schedule
      1 attached hereto sets forth financial data and computations evidencing
      compliance with certain covenants of the Credit Agreement, all of which data
      and
      computations are true, complete and correct. All computations are made in
      accordance with the terms of the Credit Agreement.

     

    Described
      below are the exceptions, if any, to paragraph 3 listing, in detail, the nature
