Explanatory Note

On November 20, 2009, Adaptec, Inc. (the "Company") filed a Current Report on Form 8- K for events that occurred on November 17, 2009 (the "Initial Form 8-K") reporting, in part, actions completed under the management approved restructuring plan disclosed in Item 2.05 in the Initial Form 8-K. This Amendment No. 2 to the Initial Form 8- K ("Form 8-K/A") is being filed solely to amend and supplement the information included in Item 2.05 to the Initial Form 8-K. Except as described in this Form 8-K/A, the Company has not modified or updated other disclosures contained in the Initial Form 8-K or Amendment No. 1 to the Initial Form 8-K (the "Amended Form 8-K"), which was filed with the Securities and Exchange Commission on February 10, 2010. Accordingly, this Form 8-K/A should be read in conjunction with the Initial Form 8-K and Amended Form 8-K.

Item 2.05    Costs Associated with Exit or Disposal Activities

On November 17, 2009, the Company notified affected employees in connection with the management approved restructuring plan to better align its operating costs with the continued decline in its net revenues. This resulted in a restructuring charge of $1.0 million during the Company's third quarter of fiscal 2010, of which $0.8 million related to severance and related benefits and $0.2 million related to exiting certain facilities. Further actions to this approved restructuring plan were made in the Company's fourth quarter of fiscal 2010 by notifying additional affected employees, resulting in additional restructuring costs of approximately $0.7 million in severance and related benefits. All of these charges will result in cash expenditures.
