Hologic, Inc. (Hologic)

and Gen-Probe Incorporated (Gen-Probe)

today announced that they have received written notification from Germany's Federal Cartel Office that the proposed acquisition of Gen-Probe by Hologic is cleared to proceed. As previously announced on June 19, 2012, the initial 30-day waiting period required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, expired without a request for additional information from the United States Federal Trade Commission. With the recent clearance from Germany, a required condition to close the proposed acquisition, the receipt of required anti-trust clearances has been satisfied. The acquisition remains subject to customary closing conditions, including the receipt of Gen-Probe stockholder approval. As previously announced, on April 30, 2012, Hologic agreed to acquire all of the outstanding shares of Gen-Probe for $82.75 per share in cash. A Special Meeting of Gen-Probe stockholders has been scheduled for July 31, 2012 to vote on the pending transaction with Hologic. Gen-Probe stockholders of record as of June 29, 2012 are entitled to vote at the Special Meeting. The transaction is expected to close on or about August 1, 2012. Additional
