State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q,10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Ultralife Corporation (the “Company”) is unable to file its Quarterly Report on Form 10-Q for the fiscal quarter ended June 28, 2009 (the “Form 10-Q”) by the August 7, 2009 prescribed due date without unreasonable effort or expense because the Company and the banks that form the lending group for the Company’s credit facility had to finalize the terms and conditions of a waiver and amendment number one to the Company’s amended and restated credit agreement. The Company believes that this information should be included in the Form 10-Q and required additional time to obtain requisite board of directors approval and to revise the Form 10-Q to reflect this event. The Company intends to file the Form 10-Q on or prior to the fifth calendar day following the prescribed due date.
