Nabors Industries Announces Exercise of Over-Allotment Option on Notes

Nabors Industries Ltd. (NYSE: NBR) announced that the initial purchasers of senior exchangeable notes due 2011 (the "Notes") of its wholly-owned subsidiary, Nabors Industries, Inc. ("NII") notified Nabors that they were exercising in full their right pursuant to the Purchase Agreement, dated May 18, 2006, among Nabors, NII and the initial purchasers, to purchase an additional $250 million in aggregate principal amount of Notes (the "Additional Notes") to cover over-allotments in the initial private offering. The closing of the offering of Additional Notes is expected to occur on June 8, 2006.

The Additional Notes are being issued on the same terms as the initial closing, including increases to the size of the exchangeable note hedge transactions and the separate warrant transactions, effectively increasing the exchange price of the Notes from approximately $45.83 under the terms of the Notes to $54.64 per share of Nabors' Common Shares from the perspective of Nabors, representing a 55% premium based on the last reported sales price on the New York Stock Exchange of $35.25 per share on May 17, 2006, the date of pricing, and a 66.8% premium over the last reported sales price of $32.75 today, June 7, 2006. On a consolidated basis, Nabors will pay approximately $15 million in connection with the amendment to the note hedge transactions and warrant transactions, providing net proceeds to Nabors on a consolidated basis of approximately $233 million.

NII intends to use the proceeds of the issuance of Additional Notes net of the additional cost of the note hedge transactions for general corporate purposes, which may include capital expenditures, retirement of other indebtedness, repurchases of Nabors' common shares or pursuing acquisition opportunities.
