Item 1.01 Entry Into A Material Definitive Agreement.

On August 31, 2009, Strategic Diagnostics Inc. ("we," "us," and "our") and the DuPont Qualicon Division of E. I. du Pont de Nemours and Company ("DuPont Qualicon") entered into an Amended and Restated Distribution Agreement, effective as of such date (the "Amended and Restated Distribution Agreement").

Under the Amended and Restated Distribution Agreement, the parties expanded their existing arrangement to include our proprietary RapidChek® SELECT™ products, which had previously not been covered by the arrangement, along with our RapidChek E. coli O157:H7, Salmonella and Listeria products. DuPont Qualicon markets these products outside the United States as the DuPont™ Lateral Flow System. We will continue to market its RapidChek and RapidChek SELECT line of food pathogen test systems directly in the United States and through selected distributors outside the U.S.

The term of the Agreement commenced as of August 31, 2009 and continues through December 31, 2011 and thereafter for successive one year periods unless we or DuPont Qualicon provides the other party notice of its intent not to renew at least 90 days prior to the end of the initial term or any renewal term or unless the Agreement is otherwise terminated in accordance with its terms.

A copy of this Agreement will be filed as an exhibit to the Company's Quarterly Report on SEC Form 10-Q for the quarter ended September 30, 2009.
