EnviroMetal Technologies Announces Settlement of Legal Action Against ARS Technologies.

FREEPORT, Ill. -- EnviroMetal Technologies Inc. (ETI) is pleased to announce a settlement in legal proceedings initiated in October 2004 against ARS Technologies Inc. (ARS). As a result of this settlement, the parties have reached an agreement that will result in a profitable relationship in applying ETI's core technology using ARS' patented placement methods.

John Vogan, President of ETI, stated, "ARS is one of the leading practitioners of 'source zone' clean-up using iron (via their Ferox(SM) process), so reaching this agreement will allow both firms to focus on delivering cost-effective environmental solutions to their clients. The agreement should also clarify ETI's intellectual property position for others in the industry. We plan to move forward quite quickly to evaluate ARS's proprietary iron materials to determine whether they represent a cost-effective alternative to our current commercial iron sources."

Dr. Alan Seech of Adventus added, "We will also be working with ARS to adapt their installation technologies for delivery of our EHC materials, which should represent a 'win-win' situation for all involved."

Under the agreement, all projects utilizing ARS' Ferox injection method will require the site owner to obtain a site-specific license directly from ETI. This settlement does not affect ARS' patented pneumatic fracturing and gas based atomized injection technology.

The scope of the agreement between ETI and ARS by no means grants other third party installation contractors the right to use the intellectual property of ARS without a separate licensing agreement with ARS directly.
