<P>	<FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As originally provided in the Prospectus, Perma-Fix Environmental Services, Inc. (the "Company") issued to </FONT><FONT FACE="Times New Roman" SIZE="-1">Karl H.
Ehlert </FONT><FONT SIZE="-1">("</FONT><FONT FACE="Times New Roman" SIZE="-1">Ehlert</FONT><FONT SIZE="-1">") two warrants, both dated July 24, 1997, each to purchase 175,000 shares of the Company's Common Stock for
five years, with the first having an exercise price of $2.00 per share, and the second having an exercise price of $3.00 per share
(together, the "Ehlert Warrants").  On March 12, 2002, the Board of Directors of the Company amended the second warrant by
reducing the exercise price of the second warrant from $3.00 to $2.90 per share.  The Ehlert Warrants are described under
"Summary of Securities Being Offered" in the Prospectus, are referred to in other portions of the Prospectus, and are covered by
the Prospectus.  The Company has been advised that, as security for certain loans, Ehlert pledged the Ehlert Warrants to
Landesbank Rheinland-Pfalz ("Landesbank") before his death on September 28, 2001.  Capitalized terms used herein have the same
definition as those used in the Prospectus dated January 31, 2000.</FONT></P>
