Nabors, Superior Well Report Expiration of HSR Waiting Period

Nabors and Superior Well Services announced that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 relating to Nabors' proposed acquisition of Superior Well Services has expired without a request for additional information from the U.S. Department of Justice or the Federal Trade Commission.

The transaction remains subject to the results of the outstanding Offer to Purchase, dated August 11, 2010, which is currently scheduled to expire on Wednesday, September 8, 2010. As previously announced, holders of approximately 34% of Superior Well Services' outstanding shares of common stock have entered into agreements agreeing to tender their shares. Following completion of the tender offer, Nabors will acquire any remaining shares of Superior Well Services through a second-step merger at the same price paid in the tender offer. Under the terms of the agreement approved by the boards of directors of both companies, the tender offer is conditioned on the tender of at least a majority of Superior Well Services' shares calculated on a fully diluted basis and other customary closing conditions.
