Item 1.01 Entry into a Material Definitive Agreement.

On July 14, 2015, Nabors Industries, Inc. (“NII”) and Nabors Drilling Canada Limited, each a wholly owned subsidiary of Nabors Industries Ltd. (the “Company”), and the Company entered into an amendment (“Amendment No. 1”) to the existing credit agreement dated November 29, 2012 (the “Credit Agreement”).  Amendment No. 1 increases the available borrowing capacity from US$1,500,000,000 to US$2,200,000,000, extends the maturity date to July 14, 2020 and increases the size of the accordion option from $450,000,000 to $500,000,000.  Amendment No. 1 also allows NII to request that the lenders agree to up to two one-year extensions of the maturity date.  The current rate under the revised facility has been reduced to LIBOR plus 125 bps with standby fees of 15 bps applying to the undrawn commitment. NII expects to use the extended facility to provide financial flexibility for strategic investment opportunities, debt refinancing and other corporate uses.

Under the terms of the Credit Agreement, as amended, Citigroup Global Markets Inc., Mizuho Bank, Ltd., HSBC Bank USA, N.A. and Wells Fargo Bank Securities, LLC are joint lead arrangers and bookrunners.  The lenders participating in the facility are Citibank, N.A., Mizuho Bank, Ltd., HSBC Bank USA, N.A., Wells Fargo Bank, N.A., HSBC Bank Canada, Bank of America, N.A., Bank of Tokyo-Mitsubishi UFJ, Ltd., PNC Bank, National Association, Deutsche Bank AG New York Branch, Morgan Stanley Bank, N.A., Compass Bank, U.S. Bank National Association, Goldman Sachs Bank USA, Sumitomo Mitsui Banking Corporation, Australia and New Zealand Banking Group Limited, Arab Banking Corporation, Grand Cayman Branch, and Riyad Bank, Houston Agency.
