FOR IMMEDIATE RELEASE

Roper Industries Updates 2004 Guidance

Duluth, Georgia, February 8, 2005. . .  Roper Industries, Inc. (NYSE: ROP) will provide updated guidance at an investor conference today for its 2004 adjusted diluted earnings per share of $2.67-$2.69, versus previous guidance of $2.58-$2.70. This updated guidance continues to reflect Roper’s core operating results and excludes the acquisition of TransCore and the related $5-6 million estimated non-cash write-off of deferred financing costs, net of tax, as well as the estimated $2 million non-cash inventory revaluation charge in connection with the acquisition of Neptune Technology Group Holdings, Inc., or NTGH. The Company previously announced that it will report its final results on February 23, 2005.

Non-GAAP Financial Information

The Company’s forecasted adjusted diluted earnings per share is a non-GAAP financial measure. The most directly comparable GAAP measure is not currently available because the Company’s results are still being reviewed internally and by its independent registered public accounting firm. The Company expects its diluted earnings per share to differ from its adjusted earnings per share due to the non-cash write-off of deferred financing costs in connection with its acquisition of TransCore and the NTGH inventory revaluation charge. The Company expects TransCore’s operations will not have a material effect on the Company’s 2004 diluted earnings per share.
