respect  to Maker shall constitute an event of default  hereunder

Maker  in an involuntary case, (ii) appoints a trustee, receiver,
assignee,  liquidator  or  similar  official  for  Maker  or  for

The  rights  and  remedies  of Payee under  this  Note  shall  be
cumulative and not alternative. No waiver by Payee of  any  right
or  remedy under this Note shall be effective unless in a writing
signed  by Payee. Neither the failure nor any delay in exercising
any  right, power or privilege under this Note will operate as  a
waiver of such right, power or privilege and no single or partial

privilege or the exercise of any other right, power or privilege.

Payee,  in whole or in part, by a waiver or renunciation  of  the
claim  or  right  unless in a writing, signed by  Payee;  (b)  no
waiver  that may be given by Payee will be applicable  except  in
the specific instance for which it is given; and (c) no notice to
or  demand  on  Maker  will be deemed  to  be  a  waiver  of  any
obligation  of  Maker or of the right of Payee  to  take  further
action  without notice or demand as provided in this Note.  Maker
hereby waives presentment, demand, protest and notice of dishonor
and protest.

                         August 29, 2000

     PERMA-FIX ENVIRONMENTAL SERVICES, INC., a Delaware corporation
(the "Company"), hereby certifies that RBB BANK AKTIENGESELLSCHAFT,
organized under the laws of Austria, and its permissible successors
and assigns (the "Warrant Holder" or "Holder"), for value received,
is entitled to purchase from the Company at any time after August
29, 2000, until 5:00 p.m., Eastern Daylight Savings Time on August
29, 2003, up to an aggregate of one hundred fifty thousand
(150,000) shares (the "Shares" or "Warrant Shares") of the

<PAGE>
Company's common stock, par value $.001 per share (the "Common
Stock") at an exercise price equal to $1.50 per share (the "Per
Share Exercise Price").

1.   Cash Exercise of Warrants.  Upon presentation and surrender of
this Common Stock Purchase Warrant Certificate ("Warrant
Certificate" or "this Certificate"), with the attached Form of
Election to Purchase duly executed and completed, at the principal
office of the Company at 1940 Northwest 67th Place, Gainesville,
Florida 32606-1649, together with cash or a cashier's or certified
check payable to the Company in the amount of the Per Share
Exercise Price multiplied by the number of Warrant Shares being
purchased (the "Aggregate Exercise Price"), the Company, or the
Company's transfer agent, as the case may be, shall deliver to the
Warrant Holder hereof, certificates of Common Stock which, in the
aggregate, represent the number of Warrant Shares being purchased.
The purchase rights represented by each Warrant Certificate are
exercisable at the option of the Holder thereof, in whole or in
part (but not as to fractional shares of the Common Stock
underlying the Warrants).  Warrants may be exercised to purchase
all or part of the shares of Common Stock represented thereby.  In
the case of the purchase of less than all the shares of Common
Stock purchasable under any Warrant Certificate, the Company shall
cancel said Warrant Certificate upon the surrender thereof and
shall execute and deliver a new Warrant Certificate of like tenor
for the balance of the shares of Common Stock purchasable
thereunder.

2.    Exercise by Surrender of Warrants (Cashless Exercise).    In
addition to the method of payment set forth in Section 1 and in
lieu of any cash payment required thereunder, subject to the terms
hereof, the Holder of the Warrants shall have the right at any time
and from time to time to exercise the Warrants held by such Holder
in full or in part by surrendering a Warrant Certificate in the
manner specified in Section 1 in exchange for the number of Warrant
Shares equal to the product of (x) the number of Warrant Shares as
to which the Warrants are being exercised multiplied by (y) a
fraction, the numerator of which is the Market Price (as defined in
Section 3 below) of the Warrant Shares less the Per Share Exercise
Price and the denominator of which is such Market Price.  Solely
for the purposes of this paragraph, Market Price shall be
calculated as the average of the Market Prices for each of the five
trading days preceding the date of exercise.

3.   Definition of Market Price.    As used herein, the phrase
"Market Price" at any date shall be deemed to be the average
closing bid quotation of the Company's Common Stock (i) as reported
on the National Association of Securities Dealers SmallCap
Quotation market ("NASDAQ") for the last five (5) trading days, or
(ii) if the Common Stock is not traded on NASDAQ, the average
closing price as listed on a national securities exchange for the
last five (5) trading days, or (iii) if no longer traded on NASDAQ
or listed on a national securities exchange, as determined in good
faith by resolution of the Board of Directors of the Company, based
on the best information available to it.

4.   Exchange and Transfer.  This Certificate, at any time prior to
the exercise hereof, upon presentation and surrender to the
Company, may be exchanged, alone or with other certificates of like

                               -2-
<PAGE>
tenor registered in the name of the same Warrant Holder, for
another Certificate or Certificates of like tenor in the name of
such Warrant Holder exercisable for the aggregate number of Warrant
Shares as the Certificate or Certificates surrendered.

5.   Rights and Obligations of Warrant Holder of this Certificate.
The Holder of this Certificate shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at
law or in equity; provided, however, that in the event any
certificate representing shares of Common Stock or other securities
is issued to the Holder hereof upon exercise of some or all of the
Warrants evidenced by this Warrant Certificate, such Holder shall,
for all purposes, be deemed to have become the Holder of record of
such Common Stock on the date on which this Certificate, together
with a duly executed Form of Election to Purchase, was surrendered
and payment of the Aggregate Exercise Price was made pursuant to
the terms hereof, irrespective of the date of delivery of such
share certificate.  The rights of the Holder of this Certificate
are limited to those expressed herein and the Holder of this
Certificate, by his acceptance hereof, consents and agrees to be
bound by, and to comply with, all of the provisions of this
Certificate, including, without limitation, all of the obligations
imposed upon the Warrant Holder contained in this Warrant
Certificate.  In addition, the Warrant Holder, by accepting this
Certificate, agrees that the Company may deem and treat the person
in whose name this Certificate is registered on the books of the
Company as the absolute, true and lawful owner of this Certificate
for all purposes whatsoever, and the Company shall not be affected
by any notice to the contrary.

6.   Common Stock.

     6.1  The Company covenants and agrees that all shares of
          Common Stock which may be acquired by the Holder under
          this Warrant Certificate will, when issued and upon
          delivery, be duly and validly authorized and issued,
          fully paid and nonassessable, and free from all stamp
          taxes, liens, and charges with respect to the purchase
          thereof.

     6.2  The Company covenants and agrees that it will, at all
          times, reserve and keep available an authorized number of
          shares of its Common Stock and other applicable
          securities sufficient to permit the exercise in full of
          all outstanding options, warrants and rights, including
          the Warrants; and, if at the time the number of
          authorized but unissued shares of Common Stock shall not
          be sufficient to effect the exercise of all of the
          Warrants covered by this Warrant Certificate, the Company
          will take such corporate action at its next annual
          meeting of stockholders as may be necessary to increase
          its authorized but unissued shares of Common Stock to
          such number of shares as shall be sufficient for such
          purpose, including, without limitation, engaging in
          reasonable efforts to obtain the requisite stockholder
          approval of any necessary amendment to its Certificate of
          Incorporation.

                               -3-
<PAGE>
7.   Issuance of Certificates.  As soon as possible after full or
partial exercise of this Warrant Certificate, the Company, at its
expense, will cause to be issued in the name of, and delivered to,
the Holder of this Warrant Certificate, a certificate or
certificates for the number of fully paid and nonassessable shares
of Common Stock to which that Holder shall be entitled on such
exercise.  No fractional shares will be issued on exercise of this
Warrant.  If on any exercise of this Warrant a fraction of a share
results, the Company will pay the cash value of that fractional
share, calculated on the basis of the Per Share Exercise Price.
All such certificates shall bear a restrictive legend to the effect
that, subject to the provisions of Section 8 below, the Shares
represented by such certificate have not been registered under the
Securities Act of 1933, as amended, or qualified under any state
securities laws and the Shares may not be sold or transferred in
the absence of such registration and qualification or an exemption
thereof, such legend to be substantially in the form set forth in
Section 8.2 of this Warrant Certificate.

8.   Disposition of Warrants or Shares.

     8.1  The Holder of this Warrant Certificate, by its acceptance
          thereof, agrees that (a) no public distribution of
          Warrants or Shares will be made in violation of the
          provisions of the Securities Act of 1933, as amended, and
          the Rules and Regulations promulgated thereunder
          (collectively, the "Act"), and (b) during such period as
          delivery of a prospectus with respect to Warrants or
          Shares may be required by the Act, no public distribution
          of Warrants or Shares will be made in a manner or on
          terms different from those set forth in, or without
          delivery of, a prospectus then meeting the requirements
          of Section 10 of the Act and in compliance with all
          applicable state securities laws.  The holder of this
          Warrant Certificate and each transferee hereof further
          agrees that if any distribution of any of the Warrants or
          Shares is proposed to be made by them otherwise than by
          delivery of a prospectus meeting the requirements of
          Section 10 of the Act, such action shall be taken only
          after receipt by the Company of an opinion of its
          counsel, to the effect that the proposed distribution
          will not be in violation of the Act or of applicable
          state law.  Furthermore, it shall be a condition to the
          transfer of the Warrants that any transferee thereof
          deliver to the Company his or its written agreement to
          accept and be bound by all of the terms and conditions
          contained in this Warrant Certificate.

     8.2  By acceptance hereof, the Holder represents and warrants
          that this Warrant Certificate is being acquired, and all
          Warrant Shares to be purchased upon the exercise of this
          Warrant Certificate will be acquired, by the Holder
          solely for the account of the Holder and not with a view
          to the fractionalization and distribution thereof, and
          will not be sold or transferred except in accordance with
          the applicable provisions of the Act and the rules and
          regulations promulgated thereunder, and the Holder agrees
          that neither this Warrant Certificate nor any of the
          Warrant Shares may be sold or transferred except under
          cover of a registration statement under the Act which is
          effective and current with respect to such Warrant Shares

                                 -4-
<PAGE>
          or pursuant to an opinion of counsel reasonably
          satisfactory to the Company that registration under the
          Act is not required in connection with such sale or
          transfer.  Any Warrant Shares issued upon exercise of
          this Warrant shall bear a legend to the following effect:

               The securities represented by this certificate
               have not been registered under the Securities
               Act of 1933, as amended (the "Act"), or
               qualified under applicable state securities
               laws, and are restricted securities within the
               meaning of the Act.  Such securities may not
               be sold or transferred, except pursuant to a
               registration statement under such Act and
               qualification under applicable state
               securities laws which are effective and
               current with respect to such securities or
               pursuant to an opinion of counsel reasonably
               satisfactory to the issuer of such securities
               that registration and qualification are not
               required under applicable federal or state
               securities laws or an exemption is available
               therefrom.

9.   Warrant Holder Not Shareholder.  This Warrant Certificate
shall not be deemed to confer upon the Holder any right to vote the
Warrant Shares or to consent to or receive notice as a shareholder
of the Company as such, because of this Warrant Certificate, in
respect of any matters whatsoever, or any other rights or
liabilities as a shareholder.

10.  Authorization and Approval.  The issuance of the Warrant
Shares are subject to appropriate corporate, NASDAQ and regulatory
authority approval.

11.  Anti-Dilution.

     11.1 If the Company at any time, or from time to time, while
          this Warrant Certificate is outstanding shall declare or
          pay, without consideration, any dividend on the Common
          Stock payable in Common Stock, or shall effect a
          subdivision of the outstanding shares of Common Stock
          into a greater number of shares of Common Stock (by stock
          split, reclassification or otherwise than by payment of
          a dividend in Common Stock or in any right to acquire
          Common Stock), or if the outstanding shares of Common
          Stock shall be combined or consolidated, by
          reclassification or otherwise, into a lesser number of
          shares of Common Stock, then the number of shares of
          Common Stock issuable upon the exercise of this Warrant
          Certificate or the Exercise Price shall be appropriately
          adjusted such that immediately after the happening of any
          such event, the proportionate number of shares of Common
          Stock issuable immediately prior to the happening of such
          event shall be the number of shares of Common Stock
          issuable subsequent to the happening of such event.

     11.2 In case of any consolidation or merger of the Company in
          which the Company is not the surviving entity, or in case
          of any sale or conveyance by the Company to another

                                -5-
<PAGE>
          entity of all or substantially all of the property of the
          Company as an entirety or substantially as an entirety,
          the Holder shall have the right thereafter, upon exercise
          of this Warrant, to receive the kind and amount of
          securities, cash or other property which the Holder would
          have owned or been entitled to receive immediately after
          such consolidation, merger, sale or conveyance had this
          Warrant been exercised in full immediately prior to the
          effective date of such consolidation, merger, sale or
          conveyance, and in any such case, if necessary,
          appropriate adjustment shall be made in the application
          thereafter of the provisions of this Section 11 with
          respect to the rights and interests of the Holder to the
          end that the provisions of this Section 11 thereafter
