TETERBORO, N.J., June 25 /PRNewswire/ -- Quest Diagnostics Incorporated (NYSE: DGX) announced today the tender offer consideration and the total consideration to be paid for notes validly tendered in its cash tender offer for all of its outstanding $150,000,000 10-3/4% Senior Subordinated Notes due 2006. The tender offer is subject to the terms and conditions set forth in the company's Offer to Purchase and Consent Solicitation Statement dated May 24, 2001, and will expire at 5:00 p.m., New York City time on Wednesday, June 27, 2001.

The total consideration to be paid for each validly tendered note was determined using the yield to December 15, 2001 (the earliest redemption date of the notes) of the applicable reference security (i.e., the 5-7/8% U.S. Treasury Note due November 30, 2001), plus a fixed spread of 50 basis points. The yield on the applicable reference security, as calculated by Merrill Lynch & Co., at 2:00 p.m., New York City time, on Monday, June 25, 2001, was 3.531%. Accordingly, the tender offer yield and the total consideration per $1,000 principal amount of notes, are 4.031% and $1,083.29 respectively. The tender offer consideration, which is payable to holders of notes who tendered after the consent period, is equal to the total consideration less the consent payment of $30.00, or $1,053.29 per $1,000 principal amount of notes. Payment for validly tendered notes is expected to be made on Thursday, June 28, 2001.

As of 2:00 p.m. on June 25, 2001, approximately $146.8 million, or 98% of the outstanding principal amount of the notes, have been tendered.
