WILMINGTON, MA--(Marketwire - Oct 17, 2011) - Implant Sciences Corporation (OTCQB: [ IMSC ]) (PINKSHEETS: [ IMSC ]), a high technology supplier of systems and sensors for homeland security and defense markets, today announced that it has amended its credit agreements with its senior secured investor, DMRJ Group LLC.

On September 30, 2011, the Company announced that DMRJ agreed to extend the maturity of Implant Sciences indebtedness from September 30, 2011 to March 31, 2012 and increase the amount the Company may borrow under the revolving promissory note from $15 million to $23 million. This was subject to the requirement that the Company would repay sufficient amounts of its outstanding indebtedness and other amounts owing to DMRJ such that, as of December 31, 2011, the Company's outstanding obligations owed to DMRJ would not exceed $15 million.

The amendment announced today removes the requirement that the Company reduce its outstanding indebtedness owed to DMRJ to $15 million or less by December 31, 2011.
