  On June 28, 2007, Martek Biosciences Corporation (the "Company") issued a press release announcing that the Company&#x2019;s Board had approved the sale of the Company&#x2019;s Fluorescent Detection Products business for $900,000 in cash and a common stock warrant for 7.5% of the acquiring entity.  The transaction is expected to close on June 29, 2007. The buyer, Columbia Biosciences Corporation, is a newly formed company headquartered in Columbia, Maryland that was founded and is owned by Martek Chairman Henry "Pete" Linsert, Jr., and six additional Martek employees working in the fluorescent detection area.  Upon closing, Mr. Linsert will retire from his current positions as Director and Chairman of the Board of Martek and will no longer be a part-time employee of Martek. The Martek employees working in the fluorescent detection area will join the new company. The Company had previously determined to divest itself of its Fluorescent Detection Products business in order to concentrate on its core business, and the sale was the result of a process undertaken by the Nominating and Corporate Governance Committee of the Board to consider offers for the business.  <br><br>As a result of Mr. Linsert&#x2019;s retirement, the Board will be reduced by one director and accordingly set at eight members.  The Board has elected current independent Board member Robert J. Flanagan as Chairman of the Board.  Mr. Linsert&#x2019;s retirement and the changes to the size of the Board will take effect upon the completion of the sale described above, scheduled for June 29, 2007.<br><br>A copy of the press release is attached as Exhibit 99.1 and incorporated by reference herein. <br>
