Lease property description	ASO presently leases the 60-acre site located on VAFB in California, where we own four buildings totaling over 50,000 square feet of space. The present land lease expires in July 2013, with provisions to extend the lease at the request of the lessee and the concurrence of the lessor. Upon final expiration of the land lease, all improvements on the property revert, at the lessor's option, to the lessor at no cost.
Texas Emerging Technology Fund Description	In March 2010, the Texas Emerging Technology Fund awarded 1st Detect $1.8 million for the development and marketing of the Miniature mass spectrometer, a portable mass spectrometer designed to serve the security, healthcare and industrial markets. As of June 30, 2012, 1st Detect has received $1.8 million in disbursements. The disbursed amount of $1.8 million represents a contingency through March 2020, the date of cancellation. If an event of default should occur, the principal and accrued interest would be reclassified from equity to notes payable in the consolidated financial statements as amounts due to the State of Texas. Management considers the likelihood of an event of default to be remote. As of June 30, 2012, no default events have occurred.
