Numerous products contributed to the strong first quarter growth in hip sales, including the conventional and Microplasty™ versions of the Taperloc^® Hip Stem, the M²a-Magnum™ Acetabular System, E-Poly™ Acetabular Liners, and the Regenerex^® Ringloc^®+ Modular Acetabular System, in addition to European sales of the Aura^® Hip Stem and the Exceed ABT™ (Advanced Bearing Technologies) Acetabular System.

The craniomaxillofacial fixation and internal fixation product categories reported double-digit growth during the first quarter, while electrical stimulation and external fixation sales decreased. U.S. spine sales growth was assisted by mid single-digit growth in domestic sales of spinal implants and orthobiologics for the spine. In the other products category, sales of softgoods and bracing products decreased during the first quarter of fiscal year 2009, while sports medicine devices experienced strong demand.

Financial Schedule Presentation

The Company’s unaudited condensed consolidated financial statements as of and for the three months ended August 31, 2008 and for the periods June 1 to July 11, 2007 (Predecessor) and July 12 to August 31, 2007 (Successor) and other financial data included in this prospectus supplement have been prepared in a manner that complies, in all material respects, with generally accepted accounting principles in the United States and reflects certain purchase accounting adjustments related to the Merger.

In this prospectus supplement, the June 1 to July 11, 2007 (Predecessor) and July 12 to August 31, 2007 (Successor) periods have been combined and are referred to as “combined”. The combined presentation does not comply with U.S. GAAP, but is presented because we believe it provides the most meaningful comparison of our results. The results of the Successor are not comparable to the results of the Predecessor due to the difference in basis of presentation of purchase accounting as compared to historical cost.

The Transaction

Biomet Inc. finalized the merger with LVB Acquisition Merger Sub, Inc., a wholly-owned subsidiary of LVB Acquisition, Inc. on September 25, 2007. LVB Acquisition, Inc. is indirectly owned by investment partnerships directly or indirectly advised or managed by The Blackstone Group L.P., Goldman Sachs & Co., Kohlberg Kravis Roberts & Co. L.P. and TPG Capital.

Forward-Looking Statements
