HICKSVILLE, NY--(eMediaWorld - May 21, 2009) - American Defense Systems, Inc. ("ADSI") (AMEX: EAG), a leading provider of advanced transparent and opaque armor, architectural hardening and security products for Defense and Homeland Security, was awarded a three-year, $9.9 million, indefinitely delivery/indefinite quantity, sole source contract by the U.S. Marine Corps Systems Command to install Crew Protection Kits (CPKs) on Terex MAC-50 cranes, as well as supply spare parts and field service representatives (FSRs).

The 50-ton all-terrain cranes will be fitted with ADSI CPKs on both the large driver cab and on the smaller side cab for the crane operator. ADSI plans to begin fulfilling an initial $4.5 million delivery order for CPKs in the current calendar quarter and complete it before the end of the year. Approximately $2.5 million of the award will fund FSRs over the term of the contract.

More information about the award (#M67854-09-D-5038) can be found on the DoD DefenseLINK website: www.defenselink.mil/contracts/contract.aspx?contractid=4030.

"This award continues our recent increase in orders from the U.S. military to provide protective technology to construction vehicles in support of our brave military service personnel in Iraq and Afghanistan," said ADSI's chief executive officer, Anthony J. Piscitelli. "This is one of our largest single orders to date and is part of the contract expansion we were anticipating in 2009."

"As these orders continue to come in, we believe ADSI is increasingly becoming the U.S. Military standard for CPKs," continued Piscitelli. "The growing use and installation of our CPKs strongly positions us to secure long-term recurring revenue through ongoing support, maintenance, repair, spare parts and reconditioning opportunities over the life of these vehicles. We are naturally very proud to have this responsibility of protecting our military service personnel with our state-of-the-art CPKs, which have already saved many lives and protected our brave men and women from serious injury."

This U.S. Marines Corps contract builds upon several recent U.S. Military-related awards and orders received by ADSI over the last six months, which combined are valued at more than $54 million. This includes an order representing approximately one-third of a $10 million revenue expectation from JCB Construction Equipment for CPKs through 2010.

About ADSI Crew Protection Kits

ADSI CPKs are custom designed and fitted to offer a maximum amount of security for the operator. They feature windows of fully transparent armor, opaque armor siding (ATC Aberdeen-tested and approved to meet all Operation Iraqi Freedom requirements), a patent-pending combat lock, tool-less emergency egress windows, fortified door hinges and an integrated crew comfort system. The CPKs are modular and can be applied to the vehicle either during its assembly stateside or as a retrofit in theater. ADSI employs field service representatives (FSRs) that are on the ground in Afghanistan, Iraq and Kuwait to train soldiers on the proper installation techniques and offer on-going expertise and assistance. In January 2008, ADSI was awarded the "Best Development in the Field of Armored Vehicle Survivability" prize by Defense IQ, a division of IQPC (http://defenseiq.com/Defence.aspx), an organization comprised of senior decision makers from the defense, aerospace and technology sectors, and partnered with the Institute for Defense and Government Advancement.
