~~SECURITIES~~Introductory ~~AND EXCHANGE COMMISSION~~Note

~~Washington~~On December 9, D2011, Nicor Inc.C (“Parent” or “Nicor”), an Illinois corporation and then-current parent company of Northern Illinois Gas Company, d/b/a Nicor Gas Company, an Illinois corporation (the “Company”), completed its previously announced merger with Apollo Acquisition Corp. ~~20549~~(“Merger Sub”), an Illinois corporation and a wholly owned subsidiary of AGL Resources Inc., a Georgia corporation (“AGL”), pursuant to the terms and conditions of the Agreement and Plan of Merger, dated as of December 6, 2010, as amended (the “Merger Agreement”), by and among Parent, AGL, Merger Sub and Ottawa Acquisition LLC, an Illinois limited liability company and a wholly owned subsidiary of AGL (“Merger LLC”). Pursuant to the terms of the Merger Agreement, Merger Sub was merged with and into Parent (the “Merger”), with Parent as the surviving corporation in the Merger (the “Surviving Corporation”), which was immediately followed after the effective time of the Merger (the “Effective Time”) by the merger of the Surviving Corporation with and into Merger LLC (the “Subsequent Merger,” and together with the Merger, the “Transaction”), with Merger LLC as the surviving entity in the Subsequent Merger. As a result of the Transaction, the Company is now a direct wholly owned subsidiary of Merger LLC, which is a direct wholly owned subsidiary of AGL. The following events took place in connection with the consummation of the Transaction.

~~FORM~~Item ~~8-K~~1.01. Entry Into a Material Definitive Agreement.

~~CURRENT~~The ~~REPORT~~disclosure set forth under Item 2.03 below is incorporated into this Item 1.01 by reference.

~~Pursuant~~Item to2.03. Creation ~~Section~~of 13a Direct Financial Obligation or ~~15(d)~~an Obligation under an Off-Balance Sheet Arrangement of ~~the~~a Registrant

~~Securities~~On ~~Exchange~~December ~~Act~~15, 2011, the Company entered into a Credit Agreement (the “Credit Agreement”) among the Company, as borrower, SunTrust Bank, as administrative agent and lender, Wells Fargo Bank, National Association and The Bank of ~~1934~~Tokyo-Mitsubishi UFJ, Ltd., as co-syndication agents and lenders, JPMorgan Chase Bank, N.A. and U.S. Bank National Association, as co-documentation agents and lenders, and the several banks and other financial institutions or entities from time to time parties thereto.

Pursuant to the Credit Agreement, the Company may borrow up to $700 million from time to time on a revolving basis, which, subject to certain restrictions, can be used to (i) repay indebtedness under the 3 Year Credit Agreement dated as of April 1923, ~~2011~~2010, (as amended, among the Borrower, Nicor, the lenders party thereto, and JPMorgan Chase Bank, N.A., as agent, and the 364-Day Credit Agreement dated as of April 19, 2011, as amended, among the Company, the lenders party thereto, and JPMorgan Chase Bank, N.A., as agent; (ii) support the issuance of commercial paper by the Company; (iii) fund permitted acquisitions and capital expenditures of the Company and its subsidiaries; and (iv) provide for ongoing working capital needs and general corporate purposes of the Company and its subsidiaries. The Credit Agreement includes a $75 million sub-facility for swingline loans, and has an “accordion” provision whereby the Company can request that the total amount it can borrow be increased to up to $900 million (subject to the acceptance by existing or new lenders of additional commitments). The Credit Agreement matures on December 15, 2016 (subject to adjustment pursuant to the Credit

~~Date of Report (Date of earliest event reported~~ Agreement).

~~NORTHERN~~At ~~ILLINOIS~~the ~~GAS~~Company’s ~~COMPANY~~option, interest on borrowings under the Credit Agreement will be based on either the alternate base rate or the London Inter-Bank Offered Rate (LIBOR) plus, in either case, an applicable interest margin. The alternate base rate is the highest of (i) the Federal Funds Rate, as published by the Federal Reserve Bank of New York, plus ½ of 1%, (ii) the prime commercial lending rate of Sun Trust, or (iii) the one-month LIBOR plus 1%. The applicable interest margin varies from time to time based on the Company’s then-current credit ratings for the long-term, non-credit enhanced senior unsecured debt securities of the Company (or if there is no such rating, the Company's issuer rating and/or corporate family rating, as the case may be).

~~(Doing~~As ~~Business~~of asthe ~~NICOR~~closing, ~~GAS~~and ~~COMPANY)~~based upon the Company’s current credit ratings, base rate borrowings, based on the prime rate, would bear interest, excluding any facility fee, at approximately 3.25% per annum. One-month LIBOR-based borrowings would bear interest, excluding any facility fee, at approximately 1.28%.

Under the Credit Agreement, the Company must have on a consolidated basis, a total debt to total capitalization ratio of no greater than 0.70:1.00, as of the end of any fiscal month. The Credit Agreement also contains certain other covenants that, among other things, restrict liens and encumbrances, mergers and consolidations, asset dispositions, dividends, and other restricted payments, loans, and investments, and other matters customarily restricted in such agreements. In addition, the Credit Agreement contains customary representations, affirmative covenants, and events of default for facilities of this type. Upon an uncured event of default under the Credit Agreement, all amounts owing under the Credit Agreement, if any, depending on the nature of such event of default will automatically, or may upon notice by the Administrative Agent or the requisite lenders thereunder, become immediately due and payable and the lenders may terminate their commitments.

~~1844~~The ~~Ferry~~Company ~~Road~~has had prior business relationships with most of the agents and lenders or their affiliates that are parties to the Credit Agreement, for which the Company has paid customary fees and expenses. The Company and its affiliates have also entered into hedging arrangements with certain lenders. Affiliates of certain of the lenders under the Credit Agreement have acted as underwriters for issuances of securities of the Company and affiliates of AGL.

~~Naperville~~The foregoing summary of the material terms of the Credit Agreement does not purport to be complete and is subject to, ~~Illinois~~and ~~60563-9600~~qualified in its entirety by, the full text of the Credit Agreement, which is filed herewith as Exhibit 10.1 and incorporated herein by reference.
