03/05/1998

TETERBORO, N.J., MARCH 5, 1998 – Quest Diagnostics Incorporated (NYSE: DGX) today announced that its Board of Directors has authorized an expenditure of up to $27 million to repurchase shares of its common stock over the next two years. At the current market price, approximately 1.8 million shares, or about 6% of the company's shares outstanding, could be repurchased. The company had 30.1 million shares outstanding as of February 28, 1998.

Kenneth W. Freeman, Chairman and Chief Executive Officer, said, "The repurchase program is intended to offset the shares issued in connection with certain employee benefit programs. In addition, given the price of our stock and our strong cash position, our Board believes a repurchase program at this time represents an excellent way to deliver value to our shareholders."

Under the repurchase authority, Quest Diagnostics can selectively repurchase its stock from time to time in the open market or in privately negotiated transactions, depending on market price and other factors. The repurchase authorization, which is within the limits provided by Quest Diagnostics' lending agreements, provides management with the flexibility to buy stock at its discretion, without a target price or timetable constraints.
