MADISON, N.J., May 9, 2011 /PRNewswire/ -- Quest Diagnostics Incorporated (NYSE: DGX), the world's leading provider of diagnostic testing, information and services, announced today that Spark Acquisition Corporation, its wholly owned subsidiary ("Spark"), has extended the cash tender offer for all outstanding shares of common stock of Celera Corporation (NASDAQ: CRA).  The expiration date of the subsequent offering period has been extended to 5:00 p.m., New York City time, tomorrow, Tuesday, May 10, 2011.  The subsequent offering period will not be further extended.

Computershare Trust Company, N.A., the depositary for the tender offer, has indicated that, as of 5:00 p.m., New York City time, on May 6, 2011, approximately 880,139 shares of common stock of Celera had been tendered during the subsequent offering period and Spark has accepted for payment all tendered shares.  Spark now owns approximately 51,722,734 shares of common stock of Celera, representing approximately 62.33% of Celera's outstanding shares of common stock and 59.30% of Celera's outstanding shares of common stock on a fully diluted basis (as determined pursuant to the merger agreement).  The same $8.00 per share cash consideration offered during the initial offering period will be paid to holders of Celera's common stock who tender their shares during the subsequent offering period.  The procedures for tendering shares during the subsequent offering period are the same as during the initial offering period, except that (i) the guaranteed delivery procedures may not be used during the subsequent offering period and (ii) shares tendered during the subsequent offering period may not be withdrawn.

Following the completion of the subsequent offering period, if Spark obtains at least 90% of the outstanding shares of Celera through the tender offer or otherwise, Quest Diagnostics intends to effect a short-form merger under Delaware law as promptly as practicable, without the need for a meeting of Celera stockholders.  As a result of the merger, the remaining Celera stockholders (other than Celera, Quest Diagnostics, Spark and any of their respective direct or indirect wholly owned subsidiaries, or those stockholders who properly exercise appraisal rights under Delaware law) will receive the same $8.00 per share price, in cash, without interest and subject to any required withholding of taxes, that was paid in the tender offer.  After the merger, Celera will be a wholly owned subsidiary of Quest Diagnostics, Celera shares will cease to be traded on the NASDAQ Global Select Market and Celera will no longer have reporting obligations under the Securities Exchange Act of 1934, as amended.
