Note 11. Subsequent Event

In October 2011, the FDA issued communications advising health care professionals not to use jet injector devices to administer influenza and all other vaccines, which essentially eliminated vaccine sales for retail pharmacy, public health and the military. In addition, Merial reduced its forecasted orders for our products, which we expect will have a material adverse impact our revenues and results of operations beginning in the fourth quarter of 2011.

On November 8, 2011, we announced a reduction in force, which eliminated 12 positions, and implemented a shortened work week for our remaining 20 employees. We do not anticipate significant severance or other charges related to these actions.

On November 9, 2011, based on a recommendation from our Board of Directors, Mr. Ralph Makar, our President and Chief Executive Officer, was terminated without cause for cost-cutting reasons effective November 11, 2011. In accordance with his employment agreement, Mr. Makar resigned from his position as Director effective November 9, 2011. We estimate we will incur severance charges and a liability totaling approximately $0.4 million in the fourth quarter of 2011 related to compensation due to Mr. Makar pursuant to his employment agreement. We are uncertain whether we will be able to satisfy this obligation.
