ISC8 SECURES $5 MILLION CREDIT FACILITY

COSTA MESA, CALIFORNIA – December 15, 2011 – ISC8 (Irvine Sensors Corporation) (OTCBB: IRSN.OB), a provider of intelligent Cybersecurity solutions and supporting technologies, announced today that it has secured a two-year, $5 million revolving credit facility, subject to various debt covenants. The firm has drawn down the entire $5 million available under the facility and has used approximately $1.9 million of those funds to pay off the remaining balance of a short-term secured promissory note, which was subject to monthly debt service and was fully due in July 2012. ISC8 expects to use some or all of the additional funds under the facility, as appropriate, for working capital purposes.

In connection with the execution of the new revolving credit facility, the Company issued a warrant to the new lender providing for the purchase of up to 15 million shares of the Company’s common stock at an exercise price of $0.11 per share. The number of shares purchasable through exercise of this warrant will be reduced by 5 million shares if the Company achieves certain operating results and revenue targets in calendar 2012.

Bill Joll, ISC8’s CEO and President, said “This new credit facility improves our current liquidity position and further supports the commercialization of our planned products. We particularly appreciate the assistance of our existing primary investors who were instrumental in the securing and structuring of this financial package.”
