Allen-Vanguard Corporation (the "Company" or "Allen-Vanguard") (TSX: VRS) of Ottawa, Canada confirms that the U.S. Department of Defense ("DoD") has posted an amendment to the pre-solicitation notice of intent to contract on a sole-source basis with Lockheed Martin for Symphony ECM systems for coalition forces operations. This amendment modifies the original announcement dated 19 April 2007 by changing the "up to" quantity of SYMPHONY systems from 600 to 1000. Details of the posting may be found at http://www.fbo.gov/spg/DON/NAVSEA/NAVSEAHQ/N0002407R4215/Modification%2001.html

Allen-Vanguard is the supplier of Symphony ECM component sets to Lockheed Martin under the terms of a seven year Technology License and Supply Agreement between the two companies announced January 18, 2006. The last similar order to Allen-Vanguard from Lockheed Martin was for 196 Symphony component systems at a value of approximately C$8 million.

The Company is confirming this amended intended contract notice to ensure that all investors have equal access to the DoD public posting information. The Company has no further comment pending the receipt of any order, and notes that the present DoD notice is an intent to contract and does not constitute an actual contract or obligation to contract.
