OSI Systems Expands Healthcare Group with Acquisition of UK-based Anesthesia Manufacturer and Distributor

OSI Systems Expands Healthcare Group with Acquisition of UK-based Anesthesia Manufacturer and Distributor

OSI Systems, Inc. (Nasdaq:OSIS) today announced that it has completed the acquisition of UK-based Blease Medical Holdings Limited, a privately-owned manufacturer of anesthesia systems, vaporizers and ventilators. Purchase consideration consists of an initial payment of GBP4.5 million cash and potential contingent payments of up to GBP6.25 million, based upon revenue performance targets over the next three years. For its fiscal year ending May 31, 2004 Blease had annual sales of approximately GBP10 million. OSI expects the acquisition to be earnings neutral for the remainder of fiscal 2005 ending June 30th.

Blease will join the OSI Healthcare Group, which is composed of Spacelabs Medical, Dolphin Medical and Osteometer MediTech. Blease will work closely with Spacelabs, a manufacturer and developer of patient monitoring systems, to develop and market a suite of products and applications focused on the perioperative market.

Deepak Chopra, Chairman and CEO of OSI Systems, stated, "We are pleased to welcome the customers, vendors and employees of Blease to the OSI Healthcare Group of companies. This acquisition provides Blease and Spacelabs with the opportunity to further enhance their growing presence in the perioperative market and enables us to be more competitive in the Asian and European marketplace where the bundling of anesthesia and patient monitoring systems is commonplace. Although each company will continue to do business under its own name, and there are no immediate plans to integrate the brands, opportunities for leveraging in manufacturing service and sales wherever possible will be explored. The acquisition of Blease also reaffirms OSI's long-term commitment to the healthcare market, and achieves one of the European Commissions key objectives in the divesture of Spacelabs by GE Medical in March 2004."

Dave Tilley, President of Spacelabs Medical, stated, "This acquisition is very exciting because it significantly strengthens both organizations. Working side-by-side, Spacelabs and Blease will provide reliable, global alternatives for clinicians seeking flexibility, cost-effectiveness and advanced capabilities in anesthesia and patient monitoring. Most importantly, this furthers the growth of an organization genuinely dedicated to providing its customers with more time to care."

Former Spacelabs Vice President of Global Strategic Marketing, Nicholas Ong, has been appointed as President of Blease. He will work closely with Andrew Ferguson during the transition period. Andrew Ferguson has accepted a position on the OSI Healthcare Advisory Committee at the conclusion of the transition period. "In my 16 years experience in the healthcare industry including anesthesia and patient monitoring industries I have always had a high regard for the quality and reputation of Blease and its employees. Blease and Spacelabs are an excellent fit as they operate sales and distribution networks in complementary markets. Spacelabs has relationships in USA, Europe and Asia-Pacific, while Blease has a direct UK sales force and distributors in many other key markets, including the Middle East and Africa."



Andrew Ferguson, Managing Director of Blease, welcomed the acquisition. "We are excited about this opportunity for growth and development as an OSI Healthcare Group company and the ability to work closely with Spacelabs in the perioperative market. Blease has always been a company that is committed to the philosophy of the 'Customer First', an approach that is also shared by our new partners. This will help to ensure that current Blease customers will continue to receive the high-quality attention as their patient care options expand."
