~~CURRENT~~On ~~REPORT~~December 15, 2011, Northern Illinois Gas Company, an Illinois corporation and wholly owned subsidiary of the Company, doing business as Nicor Gas Company (“Nicor Gas”), entered into a Credit Agreement (the “Credit Agreement”) among Nicor Gas, as borrower, SunTrust Bank, as administrative agent and lender, Wells Fargo Bank, National Association and The Bank of 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 ~~Section~~the Credit Agreement, Nicor Gas may borrow up to $700 million from time to time on a revolving basis, which, subject to certain restrictions, can be used to (i) 13repay orindebtedness 15under the 3 Year Credit Agreement dated as of April 23, 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 Nicor Gas, the lenders party thereto, and JPMorgan Chase Bank, N.A., as agent; (dii) support the issuance of commercial paper by Nicor Gas; (iii) fund permitted acquisitions and capital expenditures of Nicor Gas and its subsidiaries; and (iv) provide for ongoing working capital needs and general corporate purposes of Nicor Gas and its subsidiaries. The Credit Agreement includes a $75 million sub-facility for swingline loans, and has an “accordion” provision whereby Nicor Gas 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 Agreement).

~~Securities~~At ~~Exchange~~Nicor ~~Act~~Gas’ 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 ~~1934~~ (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 SunTrust, or (iii) the one-month LIBOR plus 1%. The applicable interest margin varies from time to time based on Nicor Gas’ then-current credit ratings for the long-term, non-credit enhanced senior unsecured debt securities of Nicor Gas (or if there is no such rating, Nicor Gas' issuer rating and/or corporate family rating, as the case may be).

One-month LIBOR-based borrowings would bear interest, ~~2011~~excluding any facility fee, at approximately 1.28%.

~~NICOR~~Under ~~INC~~the Credit Agreement, Nicor Gas 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.

~~(Exact~~Nicor ~~name~~Gas and the Company have had prior business relationships with most of ~~registrant~~the asagents ~~specified~~and inlenders or their affiliates that are parties to the Credit Agreement, for which Nicor Gas and the Company have paid customary fees and expenses.

Item 5.04 Temporary Suspension of Trading Under Registrant’s Employee Benefit Plans.

On December 7, 2011 Nicor Inc. (“Nicor”) sent an updated notice to its directors and executive officers regarding the beginning of a blackout period that is being imposed on the Nicor Companies Savings Investment Plan, the Nicor Gas Thrift Plan and the Birdsall Inc. Retirement Savings Plan (collectively the “401(k) Plans”) pursuant to which participants will be unable to direct or diversify investments, in or out of Nicor common stock held in the 401(k) Plans, (“401(k) Plan blackout period”). In accordance with the Securities and Exchange Commission’s Regulation BTR, Nicor previously provided its directors and executive officers with notice on October 24, 2011 (the “Initial BTR Notice”), regarding the 401(k) Plan blackout period and filed an 8-K regarding such blackout notice on October 25, 2011 (the “Initial BTR 8-K). The Initial BTR Notice and the Initial BTR 8-K are incorporated herein by this reference.

The Initial BTR Notice informed Nicor’s directors and executive officers that the 401(k) Plan blackout period would begin at 12 p.m. central time, on the trading date immediately before the Merger closing date. The updated notice informed Nicor’s directors and executive officers that the Merger closing is subject to the Illinois Commerce Commission’s (“ICC”) review and approval and the receipt and acceptance of the ICC’s written order authorizing the merger that is satisfactory to AGL and Nicor, and that pending approval of the ICC, the parties anticipate that the closing of the Merger could occur during the week of Sunday, December 4, 2011 through Saturday, December 10, 2011. Additionally, the updated notice informed Nicor’s directors and executive officers that the parties expect the 401(k) Plan blackout period to end 8-10 business days after the closing of the Merger, but the exact end date is not currently known. A copy of the updated trading blackout notice to Nicor’s directors and executive officers is attached hereto as Exhibit 99.1 and is incorporated herein by reference. During the trading blackout period and for a period of two years after the ending date of the trading blackout period, security holders, the Securities Exchange Commission and all other interested persons may obtain, without charge, information about the actual beginning and ending date of the 401(k) Plan blackout period by contacting Mr. Neil Maloney, Associate General Counsel, Nicor, Inc. 1844 West Ferry Road Naperville, IL 60563 to whom all inquiries regarding the trading blackout period should be directed.
