Pediatrix Agrees to Sell Newborn Metabolic Screening Laboratory.

FORT LAUDERDALE, Fla. -- Pediatrix Medical Group, Inc., (NYSE:PDX) has entered into a definitive agreement to sell its newborn metabolic screening laboratory to PerkinElmer, Inc., (NYSE:PKI). Specific terms of the cash transaction were not disclosed.

Pediatrix will focus its resources to support the continued expansion of its clinical and administrative competencies within the physician services sector, including anesthesiology. Pediatrix is the nation's leading provider of neonatal, maternal-fetal, pediatric cardiology and pediatric intensivist physician subspecialties, and recently launched an initiative to develop a national group of anesthesiologists with the acquisition of a northern Virginia practice.

Pediatrix expects to work with PerkinElmer to identify and conduct clinical research into possible applications for tandem mass spectrometry technology in prenatal and neonatal testing and diagnostics to improve patient care.

Pediatrix will continue to operate its separate, internally developed newborn hearing screen program, a hospital-based service that screens for possible hearing loss, usually prior to a newborn's discharge.

The closing on the sale of the laboratory to PerkinElmer is subject to customary closing conditions, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

The transaction is not expected to affect Pediatrix's recently issued earnings per share guidance for 2008.
