ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT. On December 27, 2005, the Board of Directors of Strategic Diagnostics Inc. (the "Corporation") approved the accelerated vesting, effective as of December 31, 2005, of all unvested stock options granted to employees and non-employee directors from 2002 through 2005 under the Corporation's 2000 Stock Incentive Plan, as well as options granted to the Corporation's Chief Executive Officer under his original employment agreement. The acceleration of vesting of these options will reduce non-cash compensation expense that would have been recorded in the Corporation's income statement in future periods as a result of the adoption of Financial Accounting Standards Board Statement No. 123R (Share-Based Payment) in January 2006. As a result of the acceleration, options to purchase approximately 361,000 shares of the Corporation's common stock (which represent 23% of the Corporation's currently outstanding stock options) will become exercisable on December 31, 2005. The accelerated options range in exercise price from $2.51 to $4.12 per share and the weighted average exercise price of the accelerated options is $3.41 per share. Of the 361,000 shares that will become exercisable, approximately 179,000 of these shares are "in the money" as of December 27, 2005, meaning that the exercise price is at or below the price of the Corporation's common stock on that date. The weighted average exercise price of the "in the money" shares at that date is $2.98. The options subject to acceleration included options to purchase approximately 222,000 shares held in the aggregate by executive officers and approximately 48,000 shares held in the aggregate by non-employee directors of the Corporation. Of these 270,000 shares, approximately 147,000 were "in the money" as of December 27, 2005. SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
