Explanatory Note.

This Amendment No. 4 relates to and amends the Schedule 13D initially filed jointly by John F. White, James F. Rice, Kenneth L. Wolfe, Foster L. Aborn and Kairos Partners III Limited Partnership with the Securities and Exchange Commission on November 24, 2009, as amended by Amendment No. 1 to Schedule 13D filed on December 1, 2010, by Amendment No. 2 to Schedule 13D filed on February 4, 2010 and by Amendment No. 3 to Schedule 13D filed on August 11, 2010 (collectively, the “Schedule 13D Statement”) , with respect to the Common Stock, $0.01 par value, of Osteotech, Inc. (the “Issuer”).

As used herein, the term “Partnership” refers to “Kairos Partners III Limited Partnership;” the term “Managers” refers to John F. White, James F. Rice, Kenneth L. Wolfe and Foster L. Aborn collectively; and the term “Reporting Persons” refers to the Partnership and the Managers collectively. All capitalized terms used and not expressly defined herein have the respective meanings ascribed to such terms in the Schedule 13 D Statement.

Item 4.

Purpose of Transaction

The Reporting Persons, as long-time and concerned stockholders of the Issuer, continually evaluate their alternatives with respect to their investment in the Issuer and possible means to maximize stockholder value. The Reporting Persons are considering various strategies to increase the value of the Reporting Persons’ investment in the Issuer.

Previously, on November 24, 2009, John White, one of the Reporting Persons, submitted a letter to Mr. Kenneth P. Fallon, III, Chairman of the Issuer’s board of directors. In the letter, Mr. White recommended to the Issuer’s Board of Directors that they hire a strategic advisor to explore all possibilities, including the sale of the company, in order to realize value for the Issuer’s stockholders. On February 4, 2010, Mr. White submitted another letter to Mr. Kenneth P. Fallon, III, Chairman of the Issuer’s board of directors. In the letter, Mr. White requested that the Issuer respond to his previous letter of November 24, 2009 and confirm whether the Issuer had considered hiring a strategic advisor and to inform him as to why the Issuer had adopted a stockholder rights plan on January 22, 2010. On August 11, 2010, the Reporting Persons issued a press release regarding their intent to vote for the dissident slate of directors for the board of the Issuer as proposed by the Spencer Capital Opportunity Fund, L.P., Boston Avenue Capital LLC and Heartland Advisors, Inc. at the annual meeting of shareholders to be held on August 23, 2010.

The Reporting Persons disclaim any admission that they constitute a “group”, as such term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, with any entity associated with the Issuer as a result of the issuance of the press release or by any other actions.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position and strategic direction, price levels of the Issuer’s stock, conditions in the securities market and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate by selling some or all of their shares of common stock.
