              PERMA-FIX ENVIRONMENTAL SERVICES, INC.


        Warrant for the Purchase of Shares of Common Stock


    In January 1995, PERMA-FIX ENVIRONMENTAL SERVICES, INC., a
Delaware corporation (the "Company"), issued Warrant No. 1-PESI-EW
("Blair Warrant") to D. H. BLAIR INVESTMENT BANKING CORP., or any
permitted assignee thereof ("Blair") for the purchase of seventy-
five thousand (75,000) fully paid and nonassessable shares of the
Company's common stock, par value $.001 per share ("Common Stock"). 
Under the terms of the Blair Warrant, on or about March 23, 1995,
Blair assigned various portions of the Blair Warrant  to certain
persons and retained a portion of the Blair Warrant to itself. 
This warrant ("Warrant") is issued pursuant to the partial
assignment by Blair of the Blair Warrant to reflect the unassigned
portion.  The Blair Warrant, and all warrants of like tenor which
may be issued by the Company as a result of the assignment by Blair
of all or any portion of the Blair Warrant or all warrants issued
by the Company in exchange or substitution for, or the assignment
of, or upon partial exercise of the Blair Warrant, this Warrant, or
any other warrants issued by the Company as a result of the
assignment by Blair of all or any portion of the Blair Warrant are
hereafter collectively referred to as the "Warrants."  The
individuals to whom Warrants are issued are hereinafter
collectively referred to as the "Warrant Holders."  The shares of
Common Stock issuable and issued upon exercise of the Warrants are
hereinafter collectively referred to as the "Warrant Shares" and
the price payable for each of the Warrant Shares upon such exercise
is hereinafter referred to as the "Warrant Price."

    FOR VALUE RECEIVED, the Company hereby certifies that Blair,
or any permitted assignee thereof, is entitled to purchase from the
Company, at any time in whole or from time to time in part, during
the period commencing the 1st day of January, 1996, and ending at
5:00 p.m., Atlanta, Georgia time, on December 31, 1999 (the


"Exercise Period"), seven thousand (7,000) shares of the Company's
Common Stock, $.001 par value ("Common Stock"), all of which shall
be fully paid and nonassessable, at a purchase price of Two Dollars
and 37.5 Cents ($2.375) per share, to be issued and delivered by
the Company upon the exercise of this Warrant; pursuant to the
terms hereof; provided, however, that the number of shares of
Common Stock to be issued and delivered by the Company upon the
exercise of this Warrant and the purchase price to be paid for each
such share shall be subject to adjustment from time to time as
hereinafter provided.  This Warrant and all warrants of like tenor
which may be issued by the Company in exchange or substitution for
or upon the transfer or partial exercise of this Warrant are
hereinafter collectively referred to as the "Warrant".  The shares
of Common Stock of the Company issuable and issued upon exercise of
the Warrant is hereinafter collectively referred to as the "Warrant
Shares".  The price payable for each of the Warrant Shares upon
such exercise is hereinafter referred to as the "Warrant Price",
which Warrant Price shall be Two Dollars and 37.5 Cents ($2.375)
for each Warrant Share, subject to adjustment from time to time
pursuant to Section 3 hereof.  The term "Common Stock" as
hereinafter used in this Warrant shall mean the shares of Common
Stock, par value $.001 per share, of the Company.

1.  Exercise of Warrant.  This Warrant may be exercised, as a
whole at any one time or in part from time to time, during the
Exercise Period, by the holder of this Warrant (the "Holder"), by
the surrender of this Warrant (with the subscription form at the
end hereof duly executed) at the address set forth in Section 10
hereof, together with payment in the manner hereinafter set forth
of an amount equal to the Warrant Price in effect at the date of
such exercise multiplied by the total number of Warrant Shares to
be purchased upon such exercise.  Payment for Warrant Shares shall
be made by a cashier's or certified check or money order to the
order of the Company.  If this Warrant is exercised in part, such
exercise shall be for a whole number of Warrant Shares and the
Holder shall be entitled to receive a new Warrant covering the
number of Warrant Shares in respect of which this Warrant has not
been exercised, unless this Warrant has expired pursuant to its
terms.  Upon any exercise and surrender of this Warrant, the
Company (i) will issue and deliver to the Holder a certificate or
certificates in the name of the Holder for the largest whole number
of Warrant Shares to which the Holder shall be entitled and, if
this Warrant is exercised in whole, in lieu of any fractional
Warrant Share to which the Holder otherwise might be entitled, cash
in an amount equal to the fair value of such fractional share
(determined in such reasonable manner as the Board of Directors of
the Company shall determine), and (ii) will deliver to the Holder
such other securities and properties which the Holder may be
entitled to receive upon such exercise, or the proportionate part

                                -2-

thereof if this Warrant is exercised in part, pursuant to the
provisions of this Warrant.  Upon termination of the Exercise
Period, this Warrant shall no longer be exercisable by the Holder.

2.  Reservation of Warrant Shares.  The Company agrees, that at
all times prior to the expiration of the Exercise Period, the
Company will have authorized and in reserve, and will keep
available, solely for issuance or delivery upon the exercise of the
Warrant such number of shares of the Common Stock and such amount
of other securities and properties as from time to time shall be
deliverable upon the exercise of the Warrant, free and clear of all
restrictions on sale or transfer (except as otherwise provided by
this Warrant or as may be imposed under applicable federal and
state securities laws or the applicable exchange upon which the
Common Stock may be listed) and free and clear of all preemptive
rights.

3.  Protection Against Dilution.

    3.1  Except as otherwise provided in this Section 3, if, at
         any time or from time to time after the date of this
         Warrant, the Company shall distribute to one or more of
         the holders of an aggregate of more than 10% of its
         outstanding Common Stock, (i) securities (other than of
         Common Stock or stock options, warrants or rights to
         purchase Common Stock or securities convertible into
         Common Stock granted or sold in accordance with Section
         3.8), without payment therefor, or (ii) property, other
         than cash, without payment therefor, then, and in each
         such case, the Holder, upon the exercise of this
         Warrant, shall be entitled to receive the securities
         and property which the Holder would hold on the date of
         such exercise if, on the date of this Warrant, the
         Holder had been the holder of record of the number of
         shares of the Common Stock subscribed for upon such
         exercise and, during the period from the date of this
         Warrant to and including the date of such exercise, had
         retained such shares and the securities and properties
         receivable by the Holder during such period.  Notice of
         each such distribution shall be forthwith mailed to the
         Holder.

    3.2  If, at any time or from time to time after the date of
         this Warrant, the Company shall (i) pay a dividend or
         make a distribution on its Common Stock in shares of
         Common Stock, (ii) subdivide its outstanding shares of
         Common Stock into a greater number of shares, (iii)
         combine its outstanding shares of Common Stock into a
         smaller number of shares, or (iv) issue by

                                  -3-

         reclassification of its Common Stock any shares of any
         other class of capital stock of the Company, the number
         of Warrant Shares and the Warrant Price in effect
         immediately prior to such event shall be adjusted so
         that, upon exercise of this Warrant, the Holder shall
         be entitled to purchase under this Warrant, without
         additional consideration therefor, the number of shares
         of Common Stock or other capital stock of the Company
         which he would have owned or been entitled to purchase
         immediately following the happening of any of the
         events described above in this subsection 3.2 had this
         Warrant been exercised and the Holder become the holder
         of record of the Warrant Shares purchased upon such
         exercise immediately prior to the record date fixed for
         the determination of stockholders entitled to receive
         such dividend or distribution or the effective date of
         such subdivision, combination or reclassification at a
         Warrant Price equal to the aggregate consideration
         which the Holder would have had to pay for such Warrant
         Shares immediately prior to such event divided by the
         number of Warrant Shares the Holder is entitled to
         receive immediately after such event.  An adjustment
         made pursuant to this subsection 3.2 shall become
         effective immediately after the record date in the case
         of a dividend or distribution and shall become
         effective immediately after the effective date in the
         case of a subdivision, combination or reclassification. 
         If, as a result of an adjustment made pursuant to this
         subsection 3.2, the Holder shall become entitled to
         receive shares of two or more classes of capital stock
         or shares of Common Stock and any other class of
         capital stock of the Company, the Board of Directors
         (whose determination shall be conclusive and shall be
         described in a written notice to the Holder promptly
         after such adjustment) shall determine the allocation
         of the adjusted Warrant Price between or among shares
         of such classes of capital stock or shares of Common
         Stock and such other class of capital stock.

    3.3  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 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

                                -4-

         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 3 with
         respect to the rights and interests of the Holder to
         the end that the provisions of this Section 3
         thereafter shall be correspondingly applicable, as
         nearly as may reasonably be, to such securities and
         other property.  The provisions of this subsection 3.3
         shall similarly apply to successive consolidations,
         mergers, sales or conveyances.  Notice of any such
         consolidation, merger, sale or conveyance, and of said
         provisions so proposed to be made, shall be mailed to
         the Holder not less than twenty (20) days prior to such
         event.  A sale of all or substantially all of the
         assets of the Company for a consideration consisting
         primarily of securities shall be deemed a consolidation
         or merger for the foregoing purposes.

    3.4  Except as provided in subsection 3.8 hereof, if at any
         time or from time to time after the date of this
         Warrant, the Company shall sell any shares of Common
         Stock for a consideration per share less than the
         Warrant Price in effect immediately prior to such sale,
         the Warrant Price shall be adjusted as of the date of
         such sale so that the same shall equal the price
         determined by dividing (i) the sum of (A) the number of
         shares of Common Stock outstanding immediately prior to
         such sale multiplied by the Warrant Price plus (B) the
         consideration received by the Company upon such sale,
         by (ii) the total number of shares of Common Stock
         outstanding after such sale; provided, however, that in
         no event shall the exercise price be adjusted pursuant
         to the computation under this Section 3.4 to an amount
         in excess of the Warrant Price in effect immediately
         prior to such computation.

    3.5  No adjustment of the Warrant Price shall be required
         unless such adjustment would require an increase or
         decrease of at least $0.05; provided, however, that any
         adjustments which by reason of this subsection 3.4 are
         not required to be made shall be carried forward and
         taken into account in any subsequent adjustment, and
         provided further, that adjustments shall be required
         and made in accordance with the provisions of this
         Section 3 (other than this subsection 3.4) not later
         than such time as may be required in order to preserve
         the tax-free nature of a distribution to the Holder. 
         All calculations under this Section 3 shall be made to

                                -5-

         the nearest cent or to the nearest 1/100th of a share,
         as the case may be.  Anything in this Section 3 to the
         contrary notwithstanding, the Company shall be entitled
         to make such reductions in the Warrant Price, in
         addition to those required by this Section 3, as it
         shall deem to be advisable in its discretion in order
         that any stock dividend, subdivision of shares or
         distribution of rights to purchase stock or securities
         convertible or exchangeable for stock hereafter made by
         the Company to its shareholders shall not be taxable.

    3.6  Whenever the Warrant Price is adjusted as provided in
         this Section 3 and upon any modification of the rights
         of the Holder in accordance with this Section 3, the
         Chief Financial Officer of the Company promptly shall 
         certify the Warrant Price and the number of Warrant
         Shares after such adjustment or modification, a brief
         statement of the facts requiring such adjustment or
         modification and the manner of computing the same, and
         shall cause such certificate to be mailed to the
         Holder.

    3.7  For purposes of this Section 3, in case any shares of
         Common Stock, options or securities entitling the
         holders thereof to purchase Common Stock or any
         securities entitling the holders thereof to convert
         such into Common Stock ("Convertible Securities") shall
         be or are to be sold or issued by the Company for cash,
         the net proceeds received by the Company shall be
         deemed to be the consideration received by the Company
         therefor.  If any shares of Common Stock, options or
         securities entitling the holders thereof to purchase
         Common Stock or to convert such securities into Common
         Stock shall be or are to be sold or issued for a
         consideration other than cash, the amount of the
         consideration other than cash received by the Company
         shall be deemed to be the fair value of such
         consideration as determined in good-faith by the Board
         of Directors of the Company, without deduction of any
         expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Company in
         connection therewith.

    3.8  Notwithstanding anything herein to the contrary, no
         adjustment to the Warrant Shares or the Warrant Price
         shall be required under this Section 3 as a result of
         (i) the issuance or sale of Common Stock or Convertible
         Securities by the Company as a result of the exercise
         of any options presently outstanding under the
         Company's 1991 Performance Equity Plan, as amended (the

                                 -6-

         "1991 Plan"), 1992 Outside Directors Stock Option Plan,
         as amended (the "1992 Plan"), and 1993 Nonqualified
         Stock Option Plan, as amended (the "1993 Plan") (the
         1991 Plan, 1992 Plan, and the 1993 Plan are referred to
         collectively as the "Plans"); or (ii) the issuance of
         any options which may hereafter be granted by the
         Company under any of the Plans or under any other
         employee benefit plan of the Company provided such
         options are issued with a conversion or exercise price
         equal to the fair market value of the Common Stock at
         the date of grant or any Common Stock or Convertible
         Securities hereafter issued or sold by the Company as
         a result of the exercise of any options hereafter
         granted by the Company under any Plans or under any
         other employee benefit plan of the Company; or (iii)
         the issuance or sale by the Company of any Common
         Stock, Convertible Securities, warrants or rights in
         connection with or arising out of or relating to the
         private placement described in the Revised Confidential
         Term Sheet, dated June 6, 1994, as supplemented from
         time to time (the "Private Placement"), whether such is
         now or hereafter issued or sold; or (iv) the issuance
         or sale of Common Stock or Convertible Securities after
         the date hereof upon the exercise of any rights or
         warrants outstanding as of the date hereof or the
         issuance or sale of Common Stock or Convertible Secur-
         ities after the date hereof upon the exercise of any
         rights or warrants issued by the Company in connection
         with or arising out of or relating to the Private
         Placement; or (v) the sale of any shares of Common
         Stock, Convertible Securities or warrants in a firm
         commitment underwritten public offering or the issuance
         of any shares of Common Stock or Convertible Securities
         upon the exercise or conversion of such warrants or
         Convertible Securities issued in such firm commitment
         underwritten public offering; or (vi) the issuance by
         the Company of Common Stock or any other securities to
         Quadrex Corporation or Quadrex Environmental Company,
         or their successors or assigns, under or in connection
         with or as a result of that certain Stock Purchase
         Agreement, dated March 23, 1994, as amended, between
         the Company and Quadrex Corporation and that certain
         Purchase Agreement, dated March 23, 1994, as amended,
         between the Company, Perma-Fix of Florida, Inc.,
         Quadrex Corporation and Quadrex Environmental Company.

    3.9  As used in this Section 3, the term "Common Stock"
         shall mean and include the Company's Common Stock
         authorized on the date of the original issue of the
         Warrants and shall also include any capital stock of

                                  -7-

         any class of the Company thereafter authorized which
         shall not be limited to a fixed sum or percentage in
         respect of the rights of the holders thereof to
         participate in dividends and in the distribution of
         assets upon the voluntary liquidation, dissolution or
         winding up of the Company; provided, however, that the
         shares issuable upon exercise of this Warrant shall
         include only shares of such class designated in the
         Company's Certificate of Incorporation as Common Stock
         on the date of the original issue of the Warrants or
         (i), in the case of any reclassification, change,
         consolidation, merger, sale or conveyance of the
         character referred to in Subsection 3.3 hereof, the
         stock, securities or property provided for in such
         section or (ii), in the case of any reclassification or
         change in the outstanding shares of Common Stock
         issuable upon exercise of the Warrants as a result of
         a subdivision or combination or consisting of a change
         in par value, or from par value to no par value, or
         from no par value to par value, such shares of Common
         Stock as so reclassified or changed.

    3.10 For purposes of this Section 3, in case any shares of
         Common Stock shall be or are to be sold or issued by
         the Company for cash, the net proceeds received by the
         Company shall be deemed to be the consideration
         received by the Company therefor.  If any shares of
         Common Stock shall be or are to be sold or issued for
         a consideration other than cash, the amount of the con-
         sideration other than cash received by the Company
         shall be deemed to be the fair value of such
         consideration as determined in good faith by the Board
         of Directors of the Company, without deduction of any
         expenses incurred or any underwriting commissions or
         concessions paid or allowed by the Company in con-
         nection therewith.

4.  Fully Paid Stock; Taxes.  The Company agrees that the shares
of the Common Stock represented by each and every certificate for
Warrant Shares delivered upon the exercise of the Warrant shall, at
the time of such delivery, be validly issued and outstanding, fully
paid and nonassessable, and not subject to preemptive rights, and
the Company will take all such actions as may be necessary to
assure that the par value or stated value, if any, per share of the
Common Stock is at all times equal to or less than the Warrant
Price.  The Company further covenants and agrees that it will pay,
when due and payable, any and all federal and state stamp, original
issue or similar taxes which may be payable in respect of the
issuance of any Warrant Share or certificate therefor.


                                 -8-

5.  Limited Transferability and Investment Representation.  

    5.1  This Warrant shall not be transferable or assignable by
         the Holder, except (i) to any corporation or
         association which is a successor to the Holder, or (ii)
         to one or more directors or officers of Blair, and
         shall be so transferable upon the books of the Company
         which it shall cause to be maintained for that purpose;
         provided that any such assignee shall be bound by the
         terms hereof and prior to such assignment or transfer
         such transferee or assignee shall execute such docu-
         ments as may reasonably be required by the Company to
         evidence that such assignee or transferee is bound by
         the terms hereof.  The Company may treat the registered
         holder of this Warrant as he or it appears on the
         Company's books at any time as the holder of this
         Warrant for all purposes.  The Company shall permit the
         Holder or its duly authorized attorney, upon written
         request during ordinary business hours, to inspect and
         copy or make extracts from its books showing the
         registered holder of this Warrant.  Any Warrant issued
         in substitution of this Warrant will be dated the same
         date as this Warrant.

    5.2  By acceptance hereof, the Holder represents and
         warrants that this Warrant is being acquired, and all
         Warrant Shares to be purchased upon the exercise of
         this Warrant 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 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 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 the following legend:

           The securities represented by this certificate
