College Station, Texas, June 2, 2008 - O.I. Corporation (NASDAQ: OICO) today announced that it has entered into a Value Added Resellers ("VAR") agreement with Agilent Technologies, Inc. (NYSE: A), effective June 1, 2008. Under the new VAR agreement, OI will continue building custom analytical solutions by coupling OI's selective detector and sample-introduction technologies to the Agilent 7890 GC and 5975C MS systems.

"We are pleased with this change in the status of our relationship with Agilent, the market leader for gas chromatography solutions," stated Bruce Lancaster, OI's Chief Executive Officer.
