Introduction and Background

As previously reported, on May 16, 2011, Orthovita, Inc., a Pennsylvania corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Stryker Corporation, a Michigan corporation (“Parent”), and Owl Acquisition Corporation, a Delaware corporation and an indirect wholly-owned subsidiary of Parent (“Purchaser”). Pursuant to the Merger Agreement, upon the terms and subject to the conditions thereof, Purchaser commenced a tender offer (the “Offer”) on May 27, 2011, to acquire all of the outstanding shares of common stock of the Company, $0.01 par value per share (the “Shares”), at a purchase price of $3.85 per Share, net to the seller in cash, without interest thereon and less any applicable withholding taxes (the “Offer Price”).

On June 27, 2011, Parent announced the expiration of the offering period, which expired at 12:00 midnight, New York City time, at the end of Friday, June 24, 2011 (the “Offering Period”).

On June 27, 2011, at 11:59 p.m., Eastern Daylight Time, Purchaser was merged with and into the Company (the “Merger”) pursuant to the terms of the Merger Agreement, with the Company surviving as an indirect wholly-owned subsidiary of Parent. The time of the Merger is referred to in this report as the “Effective Time.”

On June 28, 2011, in connection with the closing of the Merger, the Company received a payoff letter (the “Payoff Letter”) from LB I Group Inc., a Delaware corporation (“LB I”), pertaining to the Company’s outstanding loans and related obligations evidenced by the Senior Secured Note and Warrant Purchase Agreement, dated July 30, 2007 (the “Note Purchase Agreement”), by and between the Company and LB I and the related agreements, instruments and other documents entered into by the Company or its affiliates with or for the benefit of LB I (together with the Note Purchase Agreement, the “Loan Agreements”), including, without limitation, the 10% Senior Secured Note due July 30, 2012, dated July 30, 2007, made by the Company in favor of LB I. Pursuant to the Payoff Letter, all amounts outstanding under the Loan Agreements (totaling an aggregate of $37,498,611 (including approximately $1,633,333 in early termination fees)) were repaid, the Loan Agreements were terminated and LB I released and terminated all security interests and pledges securing the Company’s and its affiliates’ obligations under the Loan Agreements.

As a result of the consummation of the Merger and related transactions, the Company no longer fulfills the requirements for continued listing on the NASDAQ Global Market (“NASDAQ”) pursuant to NASDAQ Marketplace Rule 5450. Accordingly, on June 27, 2011, the Company requested that NASDAQ file with the Securities and Exchange Commission (“SEC”) a Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities Exchange Act of 1934, as amended, on Form 25, thereby effecting the delisting of the Shares from NASDAQ. On June 27, 2011, NASDAQ filed the Form 25 with the SEC.

On June 27, 2011, at the Effective Time, each Share issued and outstanding as of immediately prior to the Effective Time (excluding Shares held by the Company, any wholly owned subsidiary of the Company, Parent or Purchaser and Shares held by any shareholder who properly demands appraisal of his, her or its Shares) was cancelled and converted into the right to receive the Offer Price.

Section 5—Corporate Governance and Management

Parent and Purchaser have advised the Company that, based on information from American Stock Transfer and Trust Company, LLC, the depositary for the Offer, as of the expiration of the Offering Period at 12:00 Midnight, New York City time, at the end of Friday, June 24, 2011, an aggregate of 67,512,965 Shares (including approximately 1,312,608 Shares subject to guarantees of delivery) were validly tendered by Orthovita’s shareholders and not withdrawn, representing approximately 87.6% of the total outstanding Shares. All Shares that were validly tendered and not validly withdrawn have been accepted for purchase by Purchaser in accordance with the terms of the Offer and payment for such Shares has been or will be promptly made at the Offer Price. Accordingly, a change of control of Orthovita has occurred and Purchaser has acquired control.

Including payments made in connection with Shares validly tendered and not withdrawn in the Offer (which includes Shares subject to guarantees of delivery) and the Merger, the total amount of consideration payable in connection with the change of control transaction was $304,546,475. All amounts paid by Purchaser in connection with the Offer and the Merger were from Parent’s cash on hand.

Pursuant to the terms and conditions of the Merger Agreement, the directors of Purchaser immediately prior to the Effective Time shall be the directors of the Company until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. A description of the changes to the membership of the Company’s board of directors is set forth in Item 5.02 below.

In accordance with the Merger Agreement, on June 27, 2011, each of Scott Barry, Morris Cheston, Jr., Antony Koblish, Mary Paetzold, Paul Thomas, William E. Tidmore, Jr. and Paul T. Touhey, Jr. resigned as directors of the Company as of the Effective Time. Pursuant to the Merger Agreement, as of the Effective Time, Mary Anne McDonald and Tony M. McKinney (collectively, the “New Directors”), the directors of Purchaser immediately prior to the Effective Time, became directors of the Company.

In accordance with the Merger Agreement, on June 27, 2011, each of Antony Koblish, Nancy C. Broadbent, Maarten Persenaire, M.D. and Christopher H. Smith ceased to serve as officers of the Company. As of the Effective Time, Kevin A. Lobo and Wayne D. Dahlberg (collectively, the “New Officers”), officers of Purchaser immediately prior to the Effective Time, became the Company’s President and Vice President, Finance, respectively.
