NuVasive Signs Definitive Agreement to Acquire Osteocel Biologics Business from Osiris Therapeutics

Expands biologics platform for robust growth

Includes proprietary adult stem cell bone graft product and processing facility

Expects Osteocel(R) revenues of $15 million in 2008 and $25 million in 2009; no dilution to earnings per share in 2008 or 2009, excluding in-process R&D charge

SAN DIEGO, May 8 (HSMN NewsFeed) -- NuVasive, Inc. (Nasdaq: NUVA ), a medical device company focused on developing products for minimally disruptive surgical treatments for the spine, announced today that it has signed a definitive agreement to acquire the Osteocel biologics business from Osiris Therapeutics, Inc. (Nasdaq: OSIR ). The Osteocel business includes a proprietary adult stem cell bone graft product containing beneficial properties similar to autograft, as well as a processing facility with significant supply stream capacity.

Under the terms of the agreement, NuVasive will acquire the Osteocel biologics business from Osiris for $35 million in cash at closing, plus additional milestone-based contingent payments not to exceed $50 million in either cash or a combination of cash and stock, at the Company's election. The purchase price will be funded out of available cash and the transaction is not subject to financing conditions. The Company presently anticipates that the closing will occur in the third quarter of 2008, subject to Osiris stockholder approval and customary regulatory approvals.

Strategic benefits of the transaction to NuVasive:

-- Provides comprehensive stem cell biologic platform with benefits similar to autograft; -- Proprietary production process with significant capacity; -- Strengthens biologics platform for robust growth; -- Provides opportunity for additional revenue per procedure of $2,000 to $3,000; -- Complements current Formagraft® biologic product line; -- Allows for participation in all segments of the $1.5 billion U.S. biologics market; -- Leverages current market adoption of an established biologic used in over 15,000 procedures to date; and -- Includes rights to acquire next generation cultured version of product.

Osteocel is the only viable bone matrix product on the market that provides the three beneficial properties similar to autograft: osteoconduction (provides a scaffold for bone growth), osteoinduction (bone formation stimulation) and osteogenesis (production bone). Osteocel allows surgeons to offer the benefits of these properties to patients without the discomfort and potential complications of autograft harvesting, in addition to eliminating the time spent on a secondary surgical procedure. Osteocel is produced for use in spinal applications through a proprietary processing method that preserves the native stem cell population that resides in marrow rich bone.

The three main components that comprise Osteocel are cancellous bone, demineralized bone matrix (DBM) and viable MSCs native to the marrow rich bone. Found in human bone marrow, MSCs are fundamental regenerative cells in the body and promote tissue repair by modulating immune responses and protecting damaged tissue. MSCs are believed to help regulate the behavior of other bone marrow cells.

Alex Lukianov, Chairman and Chief Executive Officer, said, "This acquisition directly supports our strategy of complementing our product suite with innovative technologies. Osteocel provides our exclusive sales force with a unique stem cell-based bone graft that is synergistic with our Formagraft product and significantly enhances our biologics offering. This allows us to participate in the $1.5 billion U.S. Biologics market dominated by BMP and provides a powerful platform for future biologic product development."

Mr. Lukianov continued, "Our diligence on processing capacity indicates an established and growing supply stream for the product. The transaction is structured to encourage further capacity expansion as we transition this process. Once we have integrated the processing operations, we believe Osteocel will make strong contributions to our revenue growth."

C. Randal Mills, Ph.D., President and Chief Executive Officer of Osiris Therapeutics, said, "We are pleased to be working with NuVasive. This transaction allows Osiris to focus on the near-term commercial launch efforts of our stem cell drug products, knowing Osteocel is in the hands of a capable team with a track record of rapid growth in the spine market."

Financial Impact

NuVasive expects that the transaction will add revenues of $15 million in 2008 based on the contractual terms of existing distribution agreements, and $25 million of revenue in 2009. The Company expects the transaction to be dilutive to GAAP earnings per share in 2008, however, excluding in-process R&D charge expects no dilution in either 2008 or 2009. The Company expects to honor the current 2008 distribution agreements held by Osiris. The Company plans to provide additional guidance subsequent to the acquisition closing which is expected to occur in the third quarter of 2008. At that time, the Company will have worked through the transition plans for distribution and prepared the purchase price allocation and related intangible amortization expense.
