Period"), seventy-five thousand (75,000) shares of the Company's

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.


         This Warrant is issued in consideration of the
agreement by Blair to extend from October 31, 1994, to January 31,
1995, the due date of the remaining unpaid principal balance owing
under that certain Promissory Note, dated March 31, 1992, issued by
the Company and payable to the order of Blair, in the original
principal amount of Six Hundred Twenty-Five Thousand Dollars
($625,000.00), with interest at the rate of ten percent (10%) per
annum.  

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
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

                                 2

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
         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

                                   3

         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
         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

                                  4

         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
         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

                                  5

         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
         "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

                                -6-

         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
         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

                                    7

         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.

5.  Registration under the Securities Act of 1933.  

    5.1  Subject to the terms of this Section 5, if, at any time
         during the Exercise Period, the Company receives a
         written request from the Holder of this Warrant
         (whether or not the Holder theretofore shall have
         exercised this Warrant in whole or in part), and
         provided that at the time of such request the Holder is
         the owner of, and/or has the right pursuant to this
         Warrant to purchase Warrant Shares representing in the
         aggregate (either alone or together with Warrant Shares
         theretofore purchased and/or purchasable upon the exer-

                                    8

         cise of Warrants by other holders joining in such
         request)  seventy-five thousand (75,000) of the total
         number of Warrant Shares, the Company shall (i)
         promptly prepare and file with the Securities and
         Exchange Commission (the "Commission") a Registration
         Statement under the Securities Act of 1933 (the "Act")
         covering all of the Warrant Shares theretofore issued
         and which thereafter may be issuable upon the exercise
         of this Warrant (provided, that the audited financial
         statements to be included in such Registration
         Statement shall be the year-end financial statements
         customarily included in the Company's Annual Report on
         Form 10-K under the Securities Exchange Act of 1934
         (the "Exchange Act"), and provided further, that, if
         the request for registration is received within three
         (3) months prior to the commencement of a fiscal year
         of the Company, the Company may delay the preparation
         and filing of such Registration Statement for a period
         of not more than ninety (90) days following the
         commencement of such fiscal year in order to prepare
         and include in such Registration Statement audited
         financial statements for the immediately preceding
         fiscal year); (ii) use its reasonable efforts to cause
         such Registration Statement to become effective and to
         remain effective and current with respect to the
         Warrant Shares for an aggregate period of one hundred
         eighty (180) days (exclusive of any period during which
         the prospectus included therein shall not meet the
         requirements of Section 10 of the Act), and (iii) use
         reasonable efforts to cause the prospectus included
         therein to be available for the sale of Warrant Shares
         from time to time during such period by the holders
         thereof in ordinary brokerage transactions in the over-
         the-counter market or on any national securities
         exchange on which the Common Stock is then listed.  The
         right to demand the filing of a Registration Statement
         pursuant to this Section 5.1 shall be exercisable on
         one occasion only; provided, however, that if such
         Registration Statement is withdrawn for any reason
         prior to the earlier of (i) the sale by the Holder of
         all of the Warrant Shares or (ii) its having been
         effective for one hundred eighty (180) days (exclusive
         of any periods during which the prospectus included
         therein does not meet the requirements of Section 10 of
         the Act), then such right shall be exercisable on one
         additional occasion so long as the conditions herein-
         above set forth are satisfied on such additional
         occasion.  The Holder's rights under this Section 5.1
         shall expire and terminate at the earlier of such time
         as (i) the Holder shall have received from counsel to
         the Company an unqualified written opinion of such

                                    -9-

         counsel that the Holder has the right, pursuant to the
         provisions of Rule 144 under the Act, to sell within
         any three (3) month period all Warrant Shares then held
         and purchasable upon the exercise of Warrants by such
         Holder, or (ii) the Company has theretofore included
         the Warrant Shares within the coverage of a
         Registration Statement and such Registration Statement
         has not been withdrawn on or before such becomes
         effective, or (iii) termination of the Exercise Period.

    5.2  Subject to the terms of this Section 5, if, at any time
         during the Exercise Period, the Company proposes to
         register shares of the Company Common Stock for public
         sale in a firm commitment underwriting for its own
         account under a Form S-1, Form S-2 or Form S-3 Regis-
         tration Statement under the Act, the Company shall give
         the Holder notice of such proposed registration at
         least twenty (20) calendar days prior to the filing of
         a Registration Statement with the Commission.  At the
         written request of the Holder delivered to the Company
         within seven (7) calendar days after the receipt of the
         notice from the Company, which request shall state the
         Holder's intent to sell not less than fifty percent
         (50%) of the Warrant Shares, the Company shall use its
         reasonable efforts to register such Warrant Shares
         under the same Registration Statement otherwise being
         filed by the Company, and to use reasonable efforts to
         cause such Registration Statement to become and remain
         effective so long as the Company keeps such Regis-
         tration Statement effective as to such other Company
         Common Stock being sold for the account of the Company. 
         The Company shall not be required to include any of the
         Warrant Shares in any Registration Statement unless the
         Holder accepts the terms of the underwriting as agreed
         upon between the Company and the managing underwriter
         or underwriters, and then only in such quantity as will
         not, in the opinion of the managing underwriters,
         jeopardize the success of the offering by the Company. 
         If the total amount of the Warrant Shares requested to
         be included in the Registration Statement by the Holder
         and other shareholders of the Company that request the
         inclusion of securities of the Company in such Regis-
         tration Statement (the "Other Shareholders") exceeds
         the amount of securities that the managing underwriters
         reasonably believe compatible with the success of the
         offering, the Company shall only be required to include
         in the offering so many of the Warrant Shares held by
         the Holder and other securities of the Company held by
         the Other Shareholders as the managing underwriters
         believe will not jeopardize the success of the offering

                                  -10-

         (the Warrant Shares and other securities of the Company
         held by the Other Shareholders so included to be appor-
         tioned pro rata among the Holder and the Other
         Shareholders according to the amounts of Warrant Shares
         and other securities of the Company held by the Other
         Shareholders so requested to be included in the Regis-
         tration Statement or in such other proportions as have
         been mutually agreed by the Holder and the Other Share-
         holders); provided, however, that no such reduction
         shall be made with respect to any securities offered by
         the Company or any shareholders whose shares are
         included in such Registration Statement other than
         pursuant to piggyback registration rights.  All Warrant
         Shares registered pursuant to this Section 5 must be
         offered for sale in the public offering by the same
         underwriter or underwriters that are offering the other
         shares of the Company Common Stock being registered. 
         The Company may withdraw the Registration Statement at
         any time before it becomes effective or postpone the
         offering without obligation to or the consent of the
         Holder.  The Company will use reasonable efforts to
         obtain appropriate approvals or registrations under
         state "blue sky" securities laws. With respect to any
         such securities, however, Warrants may not be exercised
         by, or shares of Common Stock issued to, the Holder in
         any state in which such exercise would be unlawful. 
         Notwithstanding anything herein to the contrary, the
         rights of the Holder of this Warrant under this Section
         5.2 shall expire and terminate at the earlier of such
         time as: (i) the Holder shall have received from
         counsel for the Company a written opinion of such
         counsel that the Holder has the right, pursuant to the
         provisions of Rule 144 promulgated under the Act, to
         sell within any three (3) month period, all Warrant
         Shares then held or purchasable upon the exercise of
         this Warrant by the Holder or (ii) the Company has
         theretofore included the Warrant Shares within the
         coverage of a Registration Statement and such
         Registration Statement has not been withdrawn on or
         before such becomes effective.  

    5.3  The Company shall bear the expenses of preparing any
         registration statement contemplated by Section 5,
         including, without limitation, costs of complying with
         federal and state securities laws and regulations,
         attorneys' fees of the Company, accounting fees,
         printing expenses and federal and state filing fees;
         provided, however, that the Holder shall bear all
         transfer fees, underwriting commissions and discounts,

                                -11-

         and fees of counsel to the Holder relating to the
         Warrant Shares included in such Registration Statement.

    5.4  In the event any Warrant Shares are included in a
         Registration Statement pursuant to Sections 5.1 and 5.2
         hereof:

         5.4.1     Except as otherwise provided in this Section
                   5.4, to the extent permitted by law, the
                   Company will indemnify and hold harmless the
                   Holder and each other entity or person, if
                   any, controlling the Holder within the meaning
                   of either Section 15 of the Act or Section 20
                   of the Exchange Act (collectively, the
                   "Controlling Party"), against any losses,
                   claims, damages or liabilities to which the
                   Holder or the Controlling Party may become
                   subject under the Act, insofar as such losses,
                   claims, damage or liabilities (or actions in
                   respect thereof) arise out of or are based on
                   any untrue or alleged untrue statement of any
                   material fact contained in such Registration
                   Statement registering the Warrant Shares filed
                   by the Company with the Commission, including
                   any preliminary prospectus or final prospectus
                   contained therein or any amendments or supple-
                   ments thereto, or arise out of or are based
                   upon the omission or alleged omission to state
                   therein a material fact required to be stated
                   therein, or necessary to make the statements
                   therein not misleading or arise out of any

                                    -12-

                   violation by the Company of any rule or
                   regulation promulgated under the Act
                   applicable to the Company and relating to
                   action or inaction required of the Company in
                   connection with any such registration, and
                   will reimburse the Holder and such Controlling
                   Party for any legal or other expenses
                   reasonably incurred by it in connection with
                   investigating or defending any such loss,
                   claim, damage, liability or action, except as
                   otherwise provided in Section 5.4.4 below;
                   provided, however, that the indemnity
                   agreement contained in this Section 5.4.1
                   shall not apply to amounts paid in settlement
                   of any such loss, claim, damage, liability or
                   action if such settlement is effected without
                   the consent of the Company (which consent
                   shall not be unreasonably withheld) nor shall
                   the Company be liable in any such case for any
                   such loss, claim, damage, liability, or action
                   to the extent that it arises out of or is
                   based upon any untrue statement or alleged
                   untrue statement or omission or alleged
                   omission made in connection with such
                   Registration Statement, preliminary
                   prospectus, final prospectus, or amendments or
                   supplements thereto, in reliance upon and in
                   conformity with written information furnished
                   expressly for use in connection with such
                   Registration Statement by the Holder, any
                   underwriter or controlling person thereof.

         5.4.2     Except as otherwise provided in this Section
                   5.4, to the extent permitted by law, the
                   Holder will indemnify and hold harmless the
                   Company, each of its directors, each of its
                   officers who have signed the Registration
                   Statement, each person, if any, who controls
                   the Company within the meaning of the Act or
                   the Exchange Act, and each agent for the
                   Company against any losses, claims, damages,
                   or liabilities to which the Company or any
                   such director, officers, controlling person,
                   agent, or underwriter may become subject under
                   the Act, insofar as such losses, claims,
                   damages or liabilities (or actions in respect
                   thereto) arise out of or are based upon any
                   untrue statement or alleged untrue statement
                   of a material fact contained in such
                   Registration Statement, including any
                   preliminary prospectus or final prospectus
                   contained therein or any amendments or supple-
                   ments thereto, or arise out of or are based
                   upon the omission or alleged omission to state
                   therein a material fact required to be stated
                   therein or necessary to make the statements
                   therein not misleading, in each case to the
                   extent, but only to the extent, that such
                   untrue statement or omission or alleged
                   omission was made in such Registration
                   Statement, preliminary or final prospectus or
                   amendments or supplements thereto, in reliance
                   upon and in conformity with written
                   information furnished by or on behalf of the
                   Holder for use in connection with such Regis-
                   tration Statement, and the Holder will
                   reimburse any legal or other expenses
                   reasonably incurred by the Company or any such
                   director, officer, controlling person or agent

                                    -13-

                   in connection with investigating or defending
                   any such loss, claim, damage, liability or
                   action, except as otherwise provided in
                   Section 5.4.4 below; provided, however, that
                   the indemnity agreement contained in this
                   Section 5.4.2 shall not apply to amounts paid
                   in settlement of any such loss, claim, damage,
                   liability or action if such settlement is
                   effected without the consent of the Holder
                   (which consent shall not be unreasonably
                   withheld), and that the obligation of the
                   Holder hereunder shall be limited to an amount
                   equal to the proceeds to the Holder of Warrant
                   Shares sold pursuant thereto.

         5.4.3     If the indemnification provided for in this
                   Section 5 is unavailable to an indemnified
                   party in respect to any losses, claims,
                   damages or liabilities referred to herein,
                   then the indemnifying party, in lieu of
                   indemnifying such indemnified party hereunder,
                   shall contribute to the amount paid or payable
                   by such indemnified party as a result of such
                   losses, claims, damages or liabilities (i) in
                   such proportion as is appropriate to reflect
                   the relative benefits received by the
                   indemnifying party, on the one hand, and the
                   indemnified party, on the other hand, from the
                   offering of the securities in the Registration
                   Statement or (ii) if the allocation provided
                   by clause (i) above is not permitted by
                   applicable law, in such proportion as is
                   appropriate to reflect not only the relative
                   benefits referred to in clause (i) above but
                   also the relative fault of the indemnifying
                   party and of the indemnified party in
                   connection with the actions, statements or
                   omissions that resulted in such losses,
                   claims, damages or liabilities, as well as any
                   other relevant equitable considerations.  The
                   relative benefits received by the indemnifying
                   party and the indemnified party from the
                   offering of the securities in the Registration
                   Statement shall be deemed to be in the same
                   respective proportion as the total net
                   proceeds from the offering (after deducting
                   therefrom the expenses) received by the
                   indemnifying party and the indemnified party. 
                   The relative fault of the indemnifying party,
                   on the one hand, and the indemnified party, on

                                   -14-

                   the other hand, (i) in the case of any untrue
                   or alleged untrue statement of a material fact
                   or any omission or alleged omission to state a
                   material fact, shall be determined by
                   reference to, among other things, whether such
                   statement or omission relates to information
                   supplied by the indemnifying party or by the
                   indemnified party and the parties' relative
                   intent, knowledge, access to information and
                   opportunity to correct or prevent such
                   statement or omission, and (ii) in the case of
                   any other action or omission, shall be
                   determined by reference to, among other
                   things, whether such action or omission was
                   taken or omitted to be taken by the
                   indemnifying party or by the indemnified party
                   and the parties' relative intent, knowledge,
                   access to information and opportunity to
                   prevent such action or omission.

         5.4.4     Promptly after receipt by a person entitled to
                   indemnification pursuant to this Section 5 (an
                   "indemnified party") under this section of
                   notice of the commencement of any action, the
                   indemnified party will, if a claim in respect
                   thereof is to be made against the indemnifying
                   party under this Section 5.4, notify in
                   writing the indemnifying party of the
                   commencement thereof; but the omission so to
                   notify the indemnifying party will not relieve
                   it from any liability which it may have to the
                   indemnified party otherwise than under this
                   Section.  In case any such action is brought
                   against an indemnified party, and it notifies
                   the indemnifying part of the commencement
                   thereof, the indemnifying party will be
                   entitled to participate in and, to the extent
                   that it may wish, jointly with any other
                   indemnifying party similarly notified, to
                   assume the defense thereof, subject to the
                   provisions herein stated, with counsel reason-
                   ably satisfactory to the indemnified party,
                   and after notice from the indemnifying party
                   to the indemnified party of its election so to
                   assume the defense thereof, the indemnifying
                   party will not be liable to the indemnified
                   party under this Section 5.4 for any legal or
                   other expenses subsequently incurred by the
                   indemnified party in connection with the
                   defense thereof.  The indemnified party shall

                                    -15-

                   have the right to employ separate counsel in
                   any such action and to participate in the
                   defense thereof, but the fees and expenses of
                   such counsel shall be at the sole expense of
                   the indemnified party, except that the indem-
                   nifying party will pay such fees and expenses
                   of such counsel only if (i) the employment of
                   such counsel has been specifically authorized
                   in writing by the indemnifying party or (ii)
                   the named parties to any such action
                   (including any impleaded parties) include both
                   the indemnified party or parties and the
                   indemnifying party and the indemnified party
                   has been advised that there are defenses
                   available to it or them that the indemnifying
                   party or its counsel refuses to accept and in
                   which case the indemnifying party shall not
                   have the right to assume the defense of such
                   action on behalf of the indemnified party or
                   parties, it being understood, however, that
                   the indemnifying party shall not, in
                   connection with any one such action or
                   separate but substantially similar or related
                   actions in the same jurisdiction arising out
                   of the same general allegations or
                   circumstances, be liable for the reasonable
                   fees and expenses of more than one separate
                   firm of attorneys for the indemnified parties.

6.  Limited Transferability and Investment Representation.  

    6.1  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

                                 -16-

         registered holder of this Warrant.  Any Warrant issued
         in substitution of this Warrant will be dated the same
         date as this Warrant.

    6.2  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
           have not been registered under the Securities
           Act of 1933 and are restricted securities
           within the meaning thereof.  Such securities
           may not be sold or transferred except pursuant
           to a registration statement under such Act
           which is effective and current with respect to
           such securities or pursuant to an opinion of
           counsel reasonably satisfactory to the issuer
           of such securities that such sale or transfer
           is exempt from the registration requirements
           of such Act.

7.  Nasdaq; Boston Stock Exchange.  Notwithstanding anything
herein to the contrary, this Warrant may not be exercised by the
Holder until the Company has listed the Warrant Shares with the
National Association of Securities Dealers Automated Quotation
system ("Nasdaq") and the Boston Stock Exchange (the "Exchange"). 
The Company will use reasonable efforts to list the Warrant Shares
with the Nasdaq and the Exchange.

8.  Loss, etc., of Warrant.  Upon receipt of evidence satisfactory
to the Company of the loss, theft, destruction or mutilation of
this Warrant, and of indemnity reasonably satisfactory to the
Company, if lost, stolen or destroyed, and upon surrender and
cancellation of this Warrant, if mutilated, and upon reimbursement

                               -17-

of the Company's reasonable incidental expenses, the Company shall
execute and deliver to the Holder a new Warrant of like date, tenor
and denomination.

9.  Warrant Holder Not Shareholder.  This Warrant 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, in respect of any
matters whatsoever, or any other rights or liabilities as a
shareholder, prior to the exercise hereof.
