PALM BEACH GARDENS, FLORIDA – September 30, 2005 – AmeriPath, Inc., (“AmeriPath”) a leading provider of cancer diagnostics, genomics and related services, today announced it has signed a merger agreement with Specialty Laboratories, Inc. NYSE:SP (“Specialty”), a leading hospital-focused clinical reference laboratory.

Under the terms of the merger agreement, AmeriPath will acquire all common shares of Specialty that are outstanding at closing for $13.25 per share. Immediately prior to the merger, Specialty Family Limited Partnership, Specialty’s majority shareholder, and related parties, will contribute shares of Specialty for shares representing approximately 20% of the fully-diluted share capital of the resulting company, which will be privately held. The merger agreement was unanimously approved by AmeriPath’s Board of Directors.

“We are very excited to have the opportunity to combine forces with Specialty,” said Donald E. Steen, Chairman and Chief Executive Officer of AmeriPath. “We believe the two companies have complementary skill sets and service offerings. The merger will offer the opportunity to build on both companies’ leadership positions, provide access to each other’s medical and scientific expertise, expand our geographic presence and allow our companies to better support community-based medicine for enhanced patient care.”

Mr. Steen continued, “The bi-coastal lab locations that exist in the combined companies will be maintained to enhance client service levels rather than integrated, which often occurs at the clients’ expense. We believe this transaction represents a rare opportunity to strengthen both companies by leveraging and protecting their individual strengths and identities.”

Jeffrey A. Mossler, M.D., Vice Chairman of AmeriPath added, “Significant scientific discoveries in areas such as genomics and molecular diagnostics are providing pathways to personalized patient care. This is an exciting time in medicine, particularly laboratory medicine and pathology, and we believe this merger has the ability to position the new organization to offer a greater breadth of services.”

“We are pleased to announce this combination with AmeriPath, one of the leading anatomic pathology practices in the country,” said Richard K. Whitney, Chairman of the Board of Directors of Specialty. Mr. Whitney continued “We believe that customers will benefit from an expanded breadth of services and the service enhancements that will come from bi-coastal testing facilities.”

AmeriPath expects to complete the transaction by the first quarter of 2006, with the exact timing being dependent on the completion and review of necessary SEC and other filings. The transaction is subject to the satisfaction of customary closing conditions, including the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and approval by Specialty’s shareholders. AmeriPath will finance the transaction through a combination of cash on hand and committed private financing arrangements. Ropes & Gray LLP served as outside legal counsel to AmeriPath.

AmeriPath will conduct a conference call to discuss the transaction today, September 30, 2005, at 11:00 a.m. Eastern Time. The dial-in number is (888) 810-4930; participant passcode 4995712. All bondholders are encouraged to participate. There is no charge to access the event.
