2/21/2011 --- Royal DSM N.V. has announced that its tender offer to purchase all of the outstanding shares of common stock of Martek Biosciences Corporation, at a price of $31.50 per share, was successful.

The initial offering period of the tender offer expired at 5:00 p.m., New York City time, on February 18, 2011. The depositary for the tender offer has advised that, as of such time, a total of approximately 30,410,223 Martek shares of common stock were validly tendered and not withdrawn in the offer (including 2,359,558 shares tendered by notices of guaranteed delivery), representing approximately 90.6% of Martek’s currently outstanding shares, and approximately 83.6% excluding the shares tendered by notices of guaranteed delivery (or approximately 83.5% and 77.1%, respectively, calculated on a fully diluted basis). DSM has accepted for payment all validly tendered shares.

DSM further announced that it is commencing a subsequent offering period for three business days, which will expire at 12:00 midnight, New York City time, on Thursday, February 24, 2011 unless further extended. The purpose of this subsequent offering period is to enable Martek stockholders who have not previously tendered their shares of common stock in the offer to do so and promptly receive the same $31.50 per share that was paid during the initial offering period. During the subsequent offering period, tendering stockholders will not have withdrawal rights.

The subsequent offering period of the tender offer is being made pursuant to the previously announced merger agreement among DSM, Greenback Acquisition Corporation and Martek dated as of December 20, 2010.

Following completion of the subsequent offering period, DSM intends to complete a short-form merger in accordance with the merger agreement. In the short-form merger, Greenback Acquisition Corporation will merge with and into Martek and each share of Martek common stock not tendered in the tender offer, other than those as to which holders exercise appraisal rights under Delaware law and those held by DSM or Martek or their respective subsidiaries, will be converted in the merger into the right to receive $31.50 per share in cash, without interest and less any required withholding taxes. This is the same price per share paid in the tender offer.
