Item 2.   Acquisition or Disposition of Assets.
          _____________________________________

     On May 27, 1999, (i) Perma-Fix Environmental Services, Inc.
(the "Company"), Chemical Conservation Corporation; a Florida
corporation ("Chemical Florida"); Chemical Conservation of Georgia,
Inc., a Georgia corporation  ("Chemical Georgia"); The Thomas P.
Sullivan Living Trust, dated September 6, 1978 ("TPS Trust"); The
Ann L. Sullivan Living Trust, dated September 6, 1978 ("ALS
Trust"); Thomas P. Sullivan, an individual ("TPS"); and Ann L.
Sullivan, an individual, entered into a Stock Purchase Agreement
("Chem-Con Stock Purchase Agreement"), wherein the Company agreed
to purchase all of the outstanding capital stock of Chemical
Florida and Chemical Georgia from the ALS Trust pursuant to the
terms of the Chem-Con Stock Purchase Agreement, and (ii) the
Company, Chem-Met Services, Inc., a Michigan corporation ("Chem-
Met"), the TPS Trust, the ALS Trust, TPS and ALS entered into a
Stock Purchase Agreement ("Chem-Met Stock Purchase Agreement"),
whereby the Company agreed to purchase all of the outstanding
capital stock of Chem-Met from the TPS Trust pursuant to the terms
of the Chem-Met Stock Purchase Agreement.  The Chem-Con Stock
Purchase Agreement and the Chem-Met Stock Purchase Agreement are
collectively referred to as the "Stock Purchase Agreements."
Chemical Florida and Chemical Georgia are collectively referred to
as "Chem-Con."  TPS and ALS are husband and wife.

     On May 27, 1999, the Stock Purchase Agreements and related
transaction documents ("Documents") were executed and placed into
escrow pending satisfaction of certain conditions precedent to
closing.  On June 1, 1999, the conditions precedent to closing of
the Stock Purchase Agreement were completed, the Stock Purchase
Agreements were consummated and the Documents were released from
escrow.

     Under the terms of the Stock Purchase Agreements, the purchase
price paid by the Company in connection with the Chem-Con/Chem-Met
acquisition was $8,700,000, consisting of (i) $1,000,000 in cash
paid at closing, (ii) three promissory notes ("Promissory Notes"),
in the aggregate amount of $4,700,000, to be paid in equal monthly
installments of principal and interest of approximately $90,276.96
over five years and having an interest rate of 5.5% for the first
three years and 7% for the remaining two years, with payment of
such Promissory Notes being guaranteed by Chem-Met under a non-
recourse guaranty, which non-recourse guaranty is secured by
certain real estate owned by Chem-Met, and (iii) $3,000,000 paid in
the form of 1,500,000 shares of Perma-Fix Common Stock, par value
$.001 per share ("Common Stock"), paid to the ALS Trust at closing;
however, if the ALS Trust owns any of such shares of Common Stock
at the end of eighteen (18) months from the June 1, 1999, closing
date (the "Guarantee Period") and the market value (as determined
below) per share of Common Stock at the end of the Guarantee Period
is less than $2.00 per share, the Company shall pay the ALS Trust,
within ten (10) business days after the end of the Guarantee
Period, an amount equal to the sum determined by multiplying the
number of shares of Common Stock issued to the ALS Trust under the
Stock Purchase Agreements that are still owned by the ALS Trust at
the end of the Guarantee Period by $2.00 less the market value (as
determined below) of such shares of Common Stock owned by the ALS
Trust at the end of the Guarantee Period, with such amount, if any,

                                 -2-
<PAGE>

payable by the Company to the ALS Trust, at the Company's option,
in cash or in Common Stock or a combination thereof. Notwithstanding
anything to the contrary, the aggregate number of shares of Common Stock
issued or issuable under the Stock Purchase Agreements for any reason
whatsoever shall not exceed eighteen percent  (18%) of the number of issued
and outstanding shares of Common Stock on the date immediately preceding the
June 1, 1999, closing date.  The market value of each share of Common
Stock at the end of the Guarantee Period shall be determined based on the
average of the closing sale price per share of Common Stock as
reported on the NASDAQ SmallCap Market ("NASDAQ") for the five (5)
consecutive trading days ending with the trading day immediately
prior to the end of the Guarantee Period.  Under the Company's loan
agreement, the Company may only pay any such amount due the ALS
Trust at the end of the Guarantee Period in Common Stock unless the
lender agrees that the Company may satisfy all or part of such in
cash.

     For a period of thirty (30) calendar days prior to the end of
the Guarantee Period, (i) the TPS Trust, ALS Trust, TPS and ALS
shall not, directly or indirectly, or in conjunction with or
through any other person, firm, corporation, entity, partnership,
company or association, sell or dispose of or otherwise transfer
any shares of Common Stock, or other securities of the Company, and
(ii) the Company shall not, and shall cause its directors to not,
buy or otherwise acquire any shares of Common Stock over the NASDAQ
(other than in connection with the exercise of any outstanding
warrants or the conversion of any outstanding options or
convertible securities of the Company, or in connection with an
underwritten public offering of Common Stock).

     The Company has listed the shares of Common Stock issued to
the ALS Trust on the NASDAQ and the Boston Stock Exchange, however,
such shares of Common Stock have not been registered with the
Securities and Exchange Commission (the "Commission") and the ALS
Trust agreed that such shares of Common Stock may be transferred
only pursuant to an effective registration statement under the
Securities Act of 1933, as amended, and any applicable state
securities laws unless there is furnished to the Company an opinion
of counsel or other evidence satisfactory to the Company's counsel,
to the effect that such registration is not required.  In addition,
such shares of Common Stock may only be transferred in accordance
with the terms of the Chem-Con Stock Purchase Agreement.  The
Company intends to File a Form D with the Commission and with
certain state agencies to describe the delivery of the 1,500,000
shares of Common Stock to the ALS Trust.

     In connection with the Stock Purchase Agreements, the ALS
Trust, the TPS Trust, ALS and TPS agreed that for a period of two
(2) years from the date of Closing, none of them shall  without the
prior consent of the Board of Directors of the Company (i)  acquire
or permit any of their affiliates to acquire beneficial ownership
of any voting securities of the Company or any rights or option to
acquire voting securities of the Company or any securities
convertible into any voting securities of the Company, with the
exception that Michael F. Sullivan and Patrick Sullivan, sons of
TPS and ALS, may acquire shares of Common Stock; (ii)  solicit, or
encourage any solicitation of, or permit any of their affiliates to
solicit, or encourage any solicitation of, (a) proxies with respect
to voting securities of the Company, or (b) tender or exchange
offers for voting securities of the Company or (c) any election
contest relating to the election of directors of the Company; or
(iii) take any action to acquire or affect the control of the

                                -3-
<PAGE>

Company, except that under the Stock Purchase Agreements, it is
recognized that the Sullivan Trusts have the right to select one
nominee to the Board of Directors of the Company under certain
limited conditions.  In connection with the closing of the Stock
Purchase Agreements, a new seat was created on the Board of Directors
of the Company and TPS was appointed to fill such vacant seat.

     The cash portion of the purchase price for Chem-Con and Chem-
Met were obtained through borrowing from the Company's primary
lender, Congress Financial Corporation (Florida) ("Congress"), as
described below.  The Company anticipates that the Promissory Notes
will be paid with working capital generated from operations and/or
borrowing under the Company's revolving credit facility with
Congress. In connection with the closing, using funds borrowed from
Congress, the Company paid an aggregate of approximately $3,842,560
to satisfy certain obligations of Chem-Met.

     The principal businesses of Chem-Con and Chem-Met are the
collection, treatment, and recycling of industrial and hazardous
waste, including waste oils, water and miscellaneous solid waste.
Chemical Florida operates a permitted treatment and storage
facility and transfer station that also serves as the base for a
private trucking fleet; Chemical Georgia treats hazardous waste and
recycles solvents and Chem-Met treats and stabilizes inorganic
wastes and maintains a government services division that is focused
principally on the Defense Revitalization and Marketing Services
market.  The Company intends to continue using the Chem-Con and
Chem-Met facilities for substantially the same purposes as such
were being used prior to the acquisition by the Company.

Item 5.  Other Events.
         ____________

     (a)  Amendment to Loan Agreement with Congress.  In connection
with the acquisition of Chem-Con and Chem-Met, on May 27, 1999, Congress,
the Company, and the Company's subsidiaries, including Chem-Con and Chem-Met
(which, when acquired by the Company, would be wholly owned subsidiaries of
the Company) entered into an Amendment and Joinder to Loan and Security
Agreement (the "Loan Amendment") dated May 27, 1999, pursuant to
which the Loan and Security Agreement ("Original Loan Agreement")
among Congress, the Company and the Company's subsidiaries was
amended to provide, among other things, (i) the credit line
being increased from $7,000,000 to $11,000,000, with the revolving line
of credit portion being determined as the maximum credit of $11,000,000,
less the term loan balance, with the exact amount that can be
borrowed under the revolving line of credit not to exceed eighty
percent (80%) of the Net Amount of Eligible Accounts (as defined in
the Original Loan Agreement) less certain reserves; (ii) the term loan
portion of the Original Loan Agreement being increased from its
current balance of approximately $1,600,000 to $3,750,000 and it shall
be subject to a four year amortization schedule payable over three
years at an interest rate of 1.75% over prime; (iii) the term of the
Original Loan Agreement, as amended, will be extended for three years
from the date of the acquisition, subject to earlier termination pursuant
to the terms of the Original Loan Agreement, as amended; (iv) Chemical
Florida, Chemical Georgia and Chem-Met being added as co-borrowers under
the Original Loan Agreement, as amended; (v) the interest rate on the
revolving line of credit will continue at 1.75% over prime, with a rate

                                -4-
<PAGE>
adjustment to 1.5% if 1999 net income applicable to Common Stock of the
Company is equal to or greater than $1,500,000 for either fiscal year ended
December 31, 1999 or 2000; (vi) the monthly service fee shall increase
from $1,700 to $2,000; (vii) government receivables will be limited to
20% of eligible accounts receivable; and (viii) certain obligations of
Chem-Met shall be paid at closing of the acquisition of Chem-Con and Chem-
Met.  The Loan Amendment became effective on June 1, 1999, when the
Stock Purchase Agreements were consummated.

     Under the terms of the Original Loan Agreement, as amended,
the Company has agreed to maintain an Adjusted Net Worth (as
defined in the Original Loan Agreement) of not less than $3,000,000
throughout the term of the Original Loan Agreement, as amended.
The Company has agreed that it will not pay any dividends on any
shares of capital stock of the Company, except that dividends may
be paid on the Company's shares of preferred stock outstanding as
of the date of the Loan Amendment (collectively, "Excepted
Preferred Stock") under the terms of the applicable Excepted
Preferred Stock and if and when declared by the Board of Directors
of the Company pursuant to Delaware General Corporation Law.
Immediately after the closing of the Stock Purchase Agreements, the
Company's availability under the revolving line of credit of the
Original Loan Agreement, as amended, was approximately
$2.0 million.  As security for the payment and performance of the
Original Loan Agreement, as amended, the Company and its subsidiaries
(including Chem-Con and Chem-Met) have granted a first security
interest in all accounts receivable, inventory, general intangibles,
equipment and certain of their other assets, as well as the mortgage
on two facilities owned by subsidiaries of the Company, and except
for certain real property owned by Chem-Met, for which a first security
interest is held by the TPS Trust and the ALS Trust as security for
Chem-Met's non-recourse guaranty of the payment of the Promissory Notes.

     (b) Election of Thomas P. Sullivan to the Board of Directors of
the Company.  Under the terms of the Stock Purchase Agreements, the
Company's Board of Directors elected Thomas P. Sullivan ("TPS") to the
Board of Directors of the Company to fill a newly created directorship.
TPS is to hold such office until the next annual meeting of shareholders
of the Company and until his successor has been elected and qualified
or until his earlier resignation or removal.  Under the Stock Purchase
Agreements, the Sullivan Trusts are entitled to have one (1) nominee
elected to the Company's Board of Directors as long as the Sullivan
Trusts own, in the aggregate, not less than 1.5 million shares of the
Company's Common Stock that the Sullivans acquired under the Stock
Purchase Agreements and the nominee is satisfactory to the Board of
Directors of the Company.  TPS is the sole trustee and primary beneficiary
of the TPS Trust, which trust owned all of the capital stock of Chem-Met
prior to the consummation of the Stock Purchase Agreements.  Ann L. Sullivan
("ALS"), wife of TPS, is the sole trustee and primary beneficiary of the
ALS Trust, which owned all of the capital stock of Chem-Con prior to the
consummation of the Stock Purchase Agreements.  TPS was the President
of Chem-Met and Chem-Con for a period in excess of five (5) years prior
to the consummation of the Stock Purchase Agreements.  TPS resides at
1021 Harvard Road, Grosse Point Park, Michigan 48320.  TPS is currently
serving as a director of Charter National Bank Corp., located in Detroit,
Michigan, and has served as a director of such bank since 1982.  TPS has

                                    -5-

           Con or its Subsidiaries as currently conducted, or

           Agreement or otherwise be, in breach of any license,
           sublicense or other agreement relating to the Chem-Con
           Intellectual Property Rights, or any material licenses,
           sublicenses and other agreements as to which Chem-Con
           or its Subsidiaries is a party and pursuant to which
           Chem-Con or its Subsidiaries is authorized to use any
           third party patents, trademarks or copyrights ("Chem-
           Con Third Party Intellectual Property Rights"),

           services rendered by or expected to be sold or services
           rendered by Chem-Con or its Subsidiaries, the breach of
           which would be reasonably likely to have a material
           adverse effect upon Chem-Con or its Subsidiaries,

           Subsidiaries with respect to their business and
           operations, and Chem-Con has provided to Perma-Fix true
           and correct copies of all such audits, reports or
           investigations. Except as set forth in such audits,
           reports and investigations, neither the Sullivans, the
           Sullivan Trusts nor Chem-Con or its Subsidiaries are
           aware of any failure to be Year 2000 Compliant of (i)
           any software products sold or licensed by Chem-Con or
           its Subsidiaries to third parties or (ii) any computer
           software products used by or licensed to Chem-Con or
           its Subsidiaries from third parties for internal use by
           Chem-Con or its Subsidiaries. For purposes of this
           Agreement, "Year 2000 Compliant" means, with respect to
           each software product referred to in the prior
           sentence, that such system (i) will accurately receive,
           record, store, provide, recognize and process all date

                                -15-

           and time data from, during, into and between the
           twentieth and twenty-first centuries; (ii) will
           accurately perform all date-dependent calculations and
           operations (including, without limitation, mathematical
           operations, sorting, comparing and reporting) from,
           during, into and between the twentieth and twenty-first
           centuries; and (iii) will not malfunction, cease to
           function or provide invalid or incorrect results as a
           result of (x) the change of century, (y) date data,
           including date data which represents or references
           different centuries or more than one century or (z) the
           occurrence of any particular date; in each case without
           human intervention, other than original data entry;
           provided, in each case, that all applications, hardware
           and other systems used in conjunction with such system
           which are not owned or licensed by Chem-Con or its
           Subsidiaries correctly exchange date data with or
           provide data to such system.  Neither Chem-Con nor its
           Subsidiaries has  provided any guarantee or warranty
           for any product sold or licensed, or services provided,
           by Chem-Con or its Subsidiaries to the effect that such
           product or service (i) complies with or accounts for
           the fact of the arrival of the year 2000 or (ii) will
           not be adversely affected with respect to
           functionality, operability, performance or volume
           capacity (including without limitation the processing
           and reporting of data) by virtue of the arrival of the
           year 2000.  Chem-Con and its Subsidiaries have
           performed audits regarding their primary suppliers,
           customers, creditors and financial service
           organizations with which they have substantial
           interaction ("Outside Persons") and have determined
           that all of these Outside Persons are substantially
           Year 2000 Compliant to the extent that there will be no
           material adverse effects to Chem-Con or its
           Subsidiaries resulting from a failure of such Outside
           Persons to be Year 2000 Compliant.  In addition,
           Schedule "S" shall set forth in detail the status of
           Chem-Con and its Subsidiaries' efforts to address the
           Year 2000 issues involving Chem-Con and its
           Subsidiaries and such Outside Persons.

             otherwise form the basis of any claim, action, demand,
             suit, proceeding, hearing, study, or investigation
             related to the manufacture, processing, recycling,
             reclamation, distribution, use, treatment, storage,

         and effect policies of insurance of the types, including

         Schedule "L" attached hereto, and will continue all of such
         insurance in full force and effect up to and until the
         Closing.  The amounts and types of such insurance policies and
         the insurance carriers issuing such policies fully meet Chem-
         Con's and its Subsidiaries' contractual, legal or regulatory
         commitments and are fully adequate to insure against risks to

         Authority and the Environmental Laws.

         Fix pursuant to the terms of this Agreement or in connection

         contemplated hereby, are, or if not now delivered, will when

4.19     Disposition of Assets.  Since September 30, 1998, neither
         Chem-Con nor its Subsidiaries have made any sale or other
         disposition of any of their properties or assets or
         surrendered any of their rights with respect thereto, or made
         any additions to their properties or assets, or entered into
         any agreements, or entered into any other transaction, except
         in each instance in the ordinary course of business or as set
         forth in Schedule "M" attached hereto, and no such sale,
         disposition, surrender, addition, agreement or transaction set
         forth in such Schedule "M" has any material adverse effect
         upon the results of operations or financial condition of Chem-
         Con or its Subsidiaries or Chem-Con's or its Subsidiaries'
         ability to conduct Chem-Con's and its Subsidiaries' business
         as currently conducted.

4.20     Obligations to Employees.  All obligations of  Chem-Con and/or
         any of its Affiliates, whether arising by operation of law,
         contract, agreement, or otherwise, for payments to trusts or
         other funds or to any governmental agency or to any employees,
         directors, officers, agents, or any other individual (or any
         of their respective heirs, legatees, beneficiaries, or legal
         representatives) with respect to profit-sharing, pension or
         retirement benefits, or any other employee benefit of any kind
         whatsoever relating to Chem-Con, its Subsidiaries or any of
         their employees, have been paid.  All legally enforceable
         obligations of Chem-Con or its Subsidiaries, whether arising
         by operation of law, contract, agreement, or otherwise, for
         bonuses or other forms of compensation or benefits which are,
         or may become, payable to its employees, directors, officers,
         agents, or any other individual (or their respective heirs,
         legatees, beneficiaries or legal representative) relating to
         Chem-Con or its Subsidiaries or any of the employees of Chem-
         Con or its Subsidiaries with respect to periods ending on or
         before the Closing have been paid, or adequate accruals for

                                  -23-
<PAGE>

         Statements.  Neither Chem-Con nor any of its Affiliates has
         any accumulated funding deficiencies, as such term is defined
         in the Employee Retirement Income Security Act of 1974
         ("ERISA") and in the Code with respect to any employee benefit
         plan as defined in ERISA maintained or established for
         employees of Chem-Con or its Subsidiaries.  Neither Chem-Con
         nor its Subsidiaries has incurred any liability to the Pension
         Benefit Guaranty Corporation ("PBGC") other than for the
         payment of insurance premiums all of which have been paid when
         due, the IRS or the Department of Labor ("DOL") with respect
         to any such employee benefit plan that affects, or might
         affect Chem-Con, and does not have any withdrawal liability
         with respect to any multiemployer pension plan ("Multiemployer
         Plan") which is subject to the Multiemployer Pension Plan
         Amendments Act of 1980.  The consummation of this Agreement
         will not result in either a complete or partial withdrawal
         from any of the Multiemployer Plans.  All of the employee
         benefit plans of which Chem-Con or any Affiliate of Chem-Con
         is the plan sponsor relating to Chem-Con and its Subsidiaries
         or any of their employees have been amended as, when and to
         the extent necessary to comply with and qualify under the
         applicable provisions of the Code; and all such employee
         benefit plans have been administered in accordance with the
         applicable provisions of the Code and ERISA.  Except as
         indicated on Schedule "N", any employee benefit plans relating
         to Chem-Con or its Subsidiaries or any of their employees
         which are pension benefit plans have received, or have applied
         for and expect to receive, determination letters from the IRS
         to the effect that such plans are qualified and exempt from
         federal income taxes under Sections 401(a) and 501(a), respectively,
         of the Code, and, no amendments have been made to any such
         employee benefit plans other than those covered by such
         determination letters or applications for such determination
         letters with respect to such amendments which have been timely
         filed with the IRS.  No determination letter received with
         respect to any employee benefit plan relating to Chem-Con or
         its Subsidiaries or any of their employees has been revoked
         nor has revocation been threatened.  Each of the employee
         benefit plans have been administered at all times and in all
         respects in accordance with their respective terms.  There are
         no pending investigations by any Governmental Authority
         involving any employee benefit plans relating to Chem-Con or
         its Subsidiaries or any of their employees, no deficiency or
         termination proceedings involving such employee benefit plans,
         and no threatened or pending claims (except for claims for
         benefits payable in the normal operation of the employee
         benefit plans), suits or proceedings against any  such
         employee benefit plan or asserting any rights or claims to
         benefits under any such employee benefit plan nor are there
         any facts which could give rise to any liability in the event
         of any such investigation, claim, suit or proceeding.  Neither
         the employee benefit plans nor any trusts created thereunder
         relating to Chem-Con or its Subsidiaries or to any of their
         employees, nor any trustee, administrator or other fiduciary
         thereof, has engaged in a "prohibited transaction" (as such
         term is defined in Section 4975 of the Code or Section 406 of the
         ERISA); and has not experienced any reportable event within the
         meaning of ERISA or other event or condition which presents a
         material risk of termination of any such employee benefit plan
         by the PBGC, has had any tax imposed upon it by the IRS for
         any alleged violation under Section 4975 of the Code, or has engaged
         in any transaction which might subject Chem-Con or its
         Subsidiaries or any such employee benefit plan to any
         liability for such tax.  The terms of any such employee

                                 -24-
<PAGE>

<PAGE>
         benefit plans comply with ERISA and the Code in all respects,
         and, any and all reporting and disclosure requirements of
         ERISA or the Code and the DOL with respect to any such
         employee benefit plan have been timely met.  The information
         supplied to the actuary by Chem-Con or its Subsidiaries, the
         Sullivans or the Sullivan Trusts for use in preparing those
         reports was complete and accurate and none of Chem-Con, the
         Sullivans nor the Sullivan Trusts has reason to believe that
         the conclusions expressed in such reports are incorrect.  In
         the event of termination of any employee benefit plan of Chem-
         Con or any of its Affiliates relating to Chem-Con or its
         Subsidiaries or to any of their employees, there will be no
         liability of Chem-Con or its Subsidiaries or the plan with
         respect to the providing of benefits accrued thereunder
         subject to future variations in levels of compensation
         assuming continued investment returns at rates actuarially
         predicted.  Further, if termination (whether complete or
         partial) of any plan has occurred, then, all liabilities with
         respect thereto have been satisfied in full and no present
         liability exists with respect to any such prior termination.
         Schedule "N" also includes a list of any and all pension or
         benefit obligations of Chem-Con and/or its Affiliates which
         have not been fully funded.

4.21     Condition of Plant, Machinery and Equipment.  Except as set
         forth on Schedule "O", all of the items of the property, plant
         and equipment owned, operated or leased by Chem-Con or its
         Subsidiaries are, in all material respects, in good condition
         and repair, reasonable wear and tear excepted, and Chem-Con
         and its Subsidiaries agree to maintain such items in good
         operating condition until the Closing.  Casualty losses to
         such property, plant and equipment are covered by insurance
         with normal industry deductibles being applicable.

4.22     Books of Account.  Chem-Con has maintained its books of
         account in accordance with GAAP, applied on a consistent basis
         with prior periods.

4.23     Stock Redemptions.  There are no shares of Chem-Con Common
         Stock which are subject to redemption or purchase in lieu of
         redemption, which prior to September 30, 1998, were not paid
         for in full.  From September 30, 1998, through the date of
         this Agreement, Chem-Con has not purchased or redeemed or
         entered into any agreement to purchase or redeem any Chem-Con
         Common Stock.

4.24     Minute Books. Chem-Con and its Subsidiaries have maintained
         their corporate minute books and all such books are current.

4.25     Indebtedness of Shareholders, etc.  Except as set forth on
         Schedule "P", none of the shareholders, Affiliates, officers,
         directors or employees of Chem-Con is (i) indebted to Chem-Con
         or its Subsidiaries, and neither Chem-Con nor its Subsidiaries
         is indebted to their Affiliates, shareholders or any of their
         officers, directors or employees, (ii) a party to or has any
         interest in a material contract, agreement or lease with Chem-
         Con or its Subsidiaries or in which Chem-Con or its
         Subsidiaries is a party to or bound by, or (iii) a customer or
         supplier of Chem-Con or its Subsidiaries, which during any one

                                -25-
<PAGE>
         of the preceding three (3) years supplied to or purchased from
         Chem-Con or its Subsidiaries a amount of property or services
         exceeding Ten Thousand Dollars ($10,000.00) in any one (1)
         year.

4.26     Business Prospects.  Since September 30, 1998, there has not
         occurred any event or other occurrence which might have a
         material adverse effect on the business or business prospects
         of Chem-Con or its Subsidiaries.

4.27     Bank Accounts; Powers of Attorney.  Schedule "Q" attached
         hereto sets forth each bank account and borrowing resolution
         authorizing officers or agents of Chem-Con or its Subsidiaries

         business on behalf of Chem-Con or its Subsidiaries with
         respect to each such account or borrowing resolution.
         Schedule "Q" also lists all powers of attorney granted by
         Chem-Con or its Subsidiaries to any other person.

4.28     Sensitive Payments.  Neither Chem-Con nor its Subsidiaries has
         made or received, and to their best  knowledge, after
         reasonable due inquiry, none of their officers, directors,

         Chem-Con or its Subsidiaries or any person acting on behalf of
         Chem-Con or its Subsidiaries, has made or received, directly
         or indirectly, any bribes, kickbacks, illegal political

             ADDITIONAL REPRESENTATIONS, WARRANTIES
      AND COVENANTS OF THE SULLIVANS AND THE SULLIVAN TRUSTS
      ______________________________________________________

    The Sullivans and the Sullivan Trusts, jointly and severally,
provide to Perma-Fix the following additional representations,
warranties and covenants:

5.1 Purchase for Investment.  The ALS Trust is acquiring the
    Perma-Fix Common Stock to be issued by Perma-Fix pursuant to
    the terms of this Agreement for the ALS Trust's own account,
    to hold for investment, with no present intention of dividing
    the ALS Trust's participation with others or reselling or
    otherwise participating, directly or indirectly, in a
    distribution thereof, and not with a view to or for sale in
    connection with any distribution thereof, except pursuant to
    a registration statement under the Securities Act and any
    applicable state securities laws, or a transaction exempt from
    registration thereunder, and shall not make any sale, transfer
    or other disposition of such shares of Perma-Fix Common Stock
    in violation of any applicable state securities laws,
    including in each instance any applicable rules and
    regulations promulgated thereunder, or in violation of the
    Securities Act and the rules and regulations promulgated

<PAGE>
    further represent and warrant that the ALS Trust is not
    acquiring the shares of Perma-Fix Common Stock issuable under
    this Agreement with a view to exercising control over
    Perma-Fix, or merging or otherwise combining Perma-Fix with
    any other person.

5.2 No Registration of Perma-Fix Common Stock.  The Sullivans and
    the Sullivan Trusts have been advised that the shares of
    Perma-Fix Common Stock issued or issuable hereunder are not
    being registered under any state securities laws on the ground
    that the issuance thereof is exempt from registration, and are
    not being registered under the Securities Act on the ground
    that this transaction is exempt from registration under
    Section 4(2) of the Securities Act and/or Regulation D
    promulgated under the Securities Act ("Regulation D") and that
    reliance by Perma-Fix on such exemptions is predicated in part
    on the Sullivans' and the Sullivans Trusts' representations as
    set forth herein.

    that Perma-Fix may refuse to permit the sale, transfer or
    disposition of the shares of Perma-Fix Common Stock to be
    issued to the ALS Trust under this Agreement unless there is
    in effect a registration statement under the Securities Act
    and any applicable state securities law covering such transfer
    or the Sullivans and/or the Sullivan Trusts furnish an opinion
    of counsel or other evidence, reasonably satisfactory to
    counsel for Perma-Fix, to the effect that such registration is
    not required.

5.4 Legend.  The Sullivans and the Sullivan Trusts understand and
    agree that stop transfer instructions will be given to Perma-
    Fix's transfer agent and that there will be placed on the
    certificate or certificates representing the Perma-Fix Common
    Stock issuable under this Agreement, any substitutions
    therefor and any certificates for additional shares which
    might be distributed with respect to such Perma-Fix Common
    Stock, a legend stating in substance:

         respects with the applicable accounting requirements of the
         Securities Act and of the published Rules and Regulations
         thereunder and (ii) on the basis of a reading of the latest
         available unaudited consolidated financial statements,
         inquiries of officers of Chem-Con and Chem-Met responsible for
         financial and accounting matters and a reading of the minutes,
         nothing has come to their attention which caused them to
         believe that (a) as of the date of the latest available
         unaudited interim financial statements prepared by Chem-Con
         and Chem-Met there was any change in the capital stock or
         long-term debt of Chem-Con, Chem-Met and their subsidiaries

         all instances for changes or decreases which the Audited

         of officers of Chem-Con and Chem-Met responsible for financial
         and accounting matters and a reading of the minutes, nothing
         has come to their attention which caused them to believe that
         (1) at a specified date within five (5) days of the Closing
         Date there was any change in the capital stock or long-term
         debt of Chem-Con and Chem-Met and their subsidiaries
         consolidated or any decreases in consolidated net current
         assets or in consolidated net assets, as compared with amounts
         shown on the September 30, 1998, consolidated Balance Sheet or
         (2) for the period from the date of the Audited Financial
         Statements prepared by Chem-Con and Chem-Met for year ended
         September 30, 1998, to a specified date within five (5) days
         of the Closing Date there were any decreases as compared with
         the corresponding period in the preceding year, in
         consolidated net revenues or in the total or per-share amounts
         of consolidated income before extraordinary items or of
         consolidated net income, except in all instances for changes

         approval of the Agreed Order (as defined below) between
         Chem-Met, IDEM, Office of the Indiana Attorney General, Four
         County Landfill Group and their respective members and the
         Four County Landfill Operable Unit #1 RD/RA Group and their

         Order during February 1999, relating to Chem-Met's settlement
         of any and all claims, liabilities or obligations of Chem-Met
         relating to or in connection with the Four County Landfill
         (the "Agreed Order") as a result of timely comments and
         objections filed during the notice and thirty (30) day comment
         period contemplated by the Agreed Order.  The Sullivans, the
         Sullivan Trusts, Perma-Fix and Chem-Met further agree that if
         the prior approval by IDEM of the Agreed Order is not
         withdrawn within a reasonable period following the expiration
         of the notice and thirty (30) day comment period contemplated
         by the Agreed Order and the final resolution of any timely
         comments or objections submitted or asserted with respect
         thereto, the obligation of the Sullivans and the Sullivan
         Trusts under this Section 11.2 shall terminate.

11.3     Notice of Claim.  Perma-Fix shall give the Sullivans and the
         Sullivan Trusts a written notice (the "Notice of Claim")
         within ninety (90) days of the discovery of any matter in
         respect of which the right to indemnification contained in
         Section 11 can be claimed.  Notwithstanding the foregoing,
         failure to give such notice will not terminate any obligation
         of the Sullivans and the Sullivan Trusts hereunder.

           works, any applications for and registrations of such
           patents, trademarks, trade names, service marks,
           copyrights, mask works, web domain addresses, and all
           processes, formulae, methods, schematics, technology,
           know-how, computer software programs or applications
           and tangible or intangible proprietary information or
           material that Chem-Met is licensed or otherwise
           possesses legally enforceable rights to use and are
           necessary to conduct the business of Chem-Met as currently
           conducted, or planned to be conducted, the absence of which would
           be reasonably likely to have a material adverse effect upon Chem-Met
           (the "Chem-Met Intellectual Property Rights").  None of the
           Chem-Met Intellectual Property Rights is subject to any outstand-
           ing order, judgment, decree, stipulation, or agreement restricting
           the use of such Chem-Met Intellectual Property Rights, and to the
           best of their knowledge none infringes on, or is being infringed
           by, other intellectual property rights of any other person or
           entity.  Chem-Met has promulgated and used commercially
           reasonable efforts to enforce and maintain any
           reasonably necessary trade secret or confidentiality
           measures regarding the Chem-Met Intellectual Property
           Rights. Chem-Met has not given and is not bound by an
           agreement or indemnification regarding Chem-Met

           Intellectual Property Rights in connection with any
           property or service produced, used or sold by Chem-Met.

    4.8.2  No Breach of License.  Neither the TPS Trust nor Chem-
           Met is, or will as a result of the execution and
           delivery of this Agreement or the performance of their
           respective obligations under this Agreement or
           otherwise be, in breach of any license, sublicense or
           other agreement relating to the Chem-Met Intellectual
           Property Rights, or any material licenses, sublicenses
           and other agreements as to which Chem-Met is a party
           and pursuant to which Chem-Met is authorized to use any
           third party patents, trademarks or copyrights ("Chem-
           Met Third Party Intellectual Property Rights"),
           including software which is used in the manufacture of,
           incorporated in, or forms a part of any product sold or
           services rendered by or expected to be sold or services
           rendered by Chem-Met, the breach of which would be
           reasonably likely to have a material adverse effect
           upon Chem-Met, except as disclosed in Schedule "K"
           hereof.

    4.8.3  Year 2000 Issues.  Schedule "S" hereof identifies each
           "Year 2000" audit, report or investigation that has
           been performed by or on behalf of Chem-Met with respect
           to its business and operations, and Chem-Met has
           provided to Perma-Fix true and correct copies of all
           such audits, reports or investigations. Except as set
           forth in such audits, reports and investigations,
           neither the Sullivans, the Sullivan Trusts nor Chem-Met
           are aware of any failure to be Year 2000 Compliant of
           (i) any software products sold or licensed by Chem-Met
           to third parties or (ii) any computer software products
           used by or licensed to Chem-Met from third parties for
           internal use by Chem-Met. For purposes of this
           Agreement, "Year 2000 Compliant" means, with respect to
           each software product referred to in the prior
           sentence, that such system (i) will accurately receive,
           record, store, provide, recognize and process all date
           and time data from, during, into and between the
           twentieth and twenty-first centuries; (ii) will
           accurately perform all date-dependent calculations and
           operations (including, without limitation, mathematical
           operations, sorting, comparing and reporting) from,
           during, into and between the twentieth and twenty-first
           centuries; and (iii) will not malfunction, cease to
           function or provide invalid or incorrect results as a
           result of (x) the change of century, (y) date data,
           including date data which represents or references
           different centuries or more than one century or (z) the
           occurrence of any particular date; in each case without
           human intervention, other than original data entry;
           provided, in each case, that all applications, hardware
           and other systems used in conjunction with such system
           which are not owned or licensed by Chem-Met correctly
           exchange date data with or provide data to such system.
           Chem-Met has not provided any guarantee or warranty for
           any product sold or licensed, or services provided, by
           Chem-Met to the effect that such product or service (i)
           complies with or accounts for the fact of the arrival
           of the year 2000 or (ii) will not be adversely affected
           with respect to functionality, operability, performance

                                12

           or volume capacity (including without limitation the
           processing and reporting of data) by virtue of the
           arrival of the year 2000.  Chem-Met has performed
           audits regarding its primary suppliers, customers,
           creditors and financial service organizations with
           which they have substantial interaction ("Outside
           Persons") and has determined that all of these Outside
           Persons are substantially Year 2000 Compliant to the
           extent that there will be no material adverse effects
           to Chem-Met resulting from a failure of such Outside
           Persons to be Year 2000 Compliant.  In addition,
           Schedule "S" shall set forth in detail the status of
           Chem-Met's efforts to address the Year 2000  issues
           relating to Chem-Met and such Outside Persons.

         or used by Chem-Met, or the conduct of Chem-Met's business, as
         presently conducted by Chem-Met, in accordance with present
         practices, after the Closing.  None of Chem-Met, the Sullivans
         nor the Sullivan Trusts is a party to, bound by, or a bene-
         ficiary of, any agreement which could prevent the use of
         assets material to Chem-Met or the conduct of business as
         currently conducted by Chem-Met in each case after the
         Closing.

         any commission or broker's or finder's fee from any of the
         parties hereto in connection with this Agreement or any of the

         the Sullivans and the Sullivan Trusts in connection with this
         Agreement and the transactions contemplated herein.  The
         Sullivans and the Sullivan Trusts shall pay to WHCA Partners

         adequate to insure against risks to which Chem-Met is normally

                                 19

4.20     Obligations to Employees.  All obligations of  Chem-Met and/or
         any of its Affiliates, whether arising by operation of law,
         contract, agreement, or otherwise, for payments to trusts or
         other funds or to any governmental agency or to any employees,
         directors, officers, agents, or any other individual (or any
         of their respective heirs, legatees, beneficiaries, or legal
         representatives) with respect to profit-sharing, pension or
         retirement benefits, or any other employee benefit of any kind
         whatsoever relating to Chem-Met or any of its employees, have
         been paid.  All legally enforceable obligations of Chem-Met,
         whether arising by operation of law, contract, agreement, or
         otherwise, for bonuses or other forms of compensation or
         benefits which are, or may become, payable to its employees,
         directors, officers, agents, or any other individual (or their
         respective heirs, legatees, beneficiaries or legal
         representative) relating to Chem-Met or any of the employees
         of Chem-Met with respect to periods ending on or before the
         Closing have been paid, or adequate accruals for payment
         thereof are reflected on the Audited Financial Statements.
         Neither Chem-Met nor any of its Affiliates has any accumulated
         funding deficiencies, as such term is defined in the Employee
         Retirement Income Security Act of 1974 ("ERISA") and in the
         Code with respect to any employee benefit plan as defined in
         ERISA maintained or established for employees of Chem-Met.
         Chem-Met has not incurred any liability to the Pension Benefit
         Guaranty Corporation ("PBGC") other than for the payment of
         insurance premiums all of which have been paid when due, the
         IRS or the Department of Labor ("DOL") with respect to any
         such employee benefit plan that affects, or might affect Chem-
         Met, and does not have any withdrawal liability with respect
         to any multiemployer pension plan ("Multiemployer Plan") which
         is subject to the Multiemployer Pension Plan Amendments Act of
         1980.  The consummation of this Agreement will not result in
         either a complete or partial withdrawal from any of the
         Multiemployer Plans.  All of the employee benefit plans of
         which Chem-Met or any Affiliate of Chem-Met is the plan
         sponsor relating to Chem-Met or any of their employees have
         been amended as, when and to the extent necessary to comply
         with and qualify under the applicable provisions of the Code;
         and all such employee benefit plans have been administered in
         accordance with the applicable provisions of the Code and
         ERISA.  Except as indicated on Schedule "N", any employee
         benefit plans relating to Chem-Met or any of their employees
         which are pension benefit plans have received, or have applied
         for and expect to receive, determination letters from the IRS
         to the effect that such plans are qualified and exempt from
         federal income taxes under Sections 401(a) and 501(a), respectively,
         of the Code, and, no amendments have been made to any such
         employee benefit plans other than those covered by such
         determination letters or applications for such determination
         letters with respect to such amendments which have been timely
         filed with the IRS.  No determination letter received with
         respect to any employee benefit plan relating to Chem-Met or
         any of its employees has been revoked nor has revocation been
         threatened.  Each of the employee benefit plans have been
         administered at all times and in all respects in accordance
         with their respective terms.  There are no pending
         investigations by any Governmental Authority involving any
         employee benefit plans relating to Chem-Met or any of its
         employees, no deficiency or termination proceedings involving
         such employee benefit plans, and no threatened or pending
         claims (except for claims for benefits payable in the normal
         operation of the employee benefit plans), suits or proceedings

                                     20
<PAGE>

         against any such employee benefit plan or asserting any
         rights or claims to benefits under any such employee benefit
         plan nor are there any facts which could give rise to any
         liability in the event of any such investigation, claim, suit
         or proceeding.  Neither the employee benefit plans nor any
         trusts created thereunder relating to Chem-Met or to any of
         their employees, nor any trustee, administrator or other
         fiduciary thereof, has engaged in a "prohibited transaction"
         (as such term is defined in Section 4975 of the Code or Section 406 of
         the ERISA); and has not experienced any reportable event within
         the meaning of ERISA or other event or condition which
         presents a material risk of termination of any such employee
         benefit plan by the PBGC, has had any tax imposed upon it by
         the IRS for any alleged violation under Section 4975 of the Code, or
         has engaged in any transaction which might subject Chem-Met or
         any such employee benefit plan to any liability for such tax.
         The terms of any such employee benefit plans comply with ERISA
         and the Code in all respects, and, any and all reporting and
         disclosure requirements of ERISA or the Code and the DOL with
         respect to any such employee benefit plan have been timely
         met.  The information supplied to the actuary by Chem-Met, the
         Sullivans or the Sullivan Trusts for use in preparing those
         reports was complete and accurate and none of Chem-Met, the
         Sullivans nor the Sullivan Trusts has reason to believe that
         the conclusions expressed in such reports are incorrect.  In
         the event of termination of any employee benefit plan of Chem-
         Met or any of its Affiliates relating to Chem-Met or to any of
         their employees, there will be no liability of Chem-Met or the
         plan with respect to the providing of benefits accrued
         thereunder subject to future variations in levels of
         compensation assuming continued investment returns at rates
         actuarially predicted.  Further, if termination (whether
         complete or partial) of any plan has occurred, then, all
         liabilities with respect thereto have been satisfied in full
         and no present liability exists with respect to any such prior
         termination.  Schedule "N" also includes a list of any and all
         pension or benefit obligations of Chem-Met and/or its
         Affiliates which have not been fully funded.

4.21     Condition of Plant, Machinery and Equipment.  Except as set
         forth on Schedule "O", all of the items of the property, plant
         and equipment owned, operated or leased by Chem-Met is, in all
         material respects, in good condition and repair, reasonable
         wear and tear excepted, and Chem-Met agrees to maintain such
         items in good operating condition until the Closing.  Casualty
         losses to such property, plant and equipment are covered by
         insurance with normal industry deductibles being applicable.

4.22     Books of Account.  Chem-Met has maintained its books of
         account in accordance with GAAP, applied on a consistent basis
         with prior periods.

4.23     Stock Redemptions.  There are no shares of Chem-Met Common
         Stock which are subject to redemption or purchase in lieu of
         redemption, which prior to September 30, 1998, were not paid
         for in full.  From September 30, 1998, through the date of
         this Agreement, Chem-Met has not purchased or redeemed or

         Agreement referencing such Exhibits and Schedules. The Exhibits and

         heretofore delivered to Lender in connection with the Original Loan
         Agreement.

construed in connection with, the Original Loan Agreement, and all
terms, covenants, conditions, representations and warranties shall
remain in full force in effect and are incorporated herein by

   may hereafter arise, so long as copies of such contracts have
   heretofore been delivered to Lender, Lender agrees that Accounts

   Accounts would otherwise be deemed to be Eligible Accounts but for

   after the date of this Amendment as to such existing contracts and
   ninety (90) days from the date of delivery of any hereafter arising

   compliance with the applicable Claims Act at all times after the
   applicable ninety (90) or one hundred and eighty (180) day period,
   as applicable, provided above for compliance with the Claims Act .
   3. Each Borrower certifies to Lender that (after giving

   effect to this Amendment) no Event of Default under the Loan
   Agreement, or event which with the passage of time or the giving of
   notice, or both, would constitute an event of default under the
   Loan Agreement, has occurred and is continuing.
   5. (a)   In no way in limitation of the provisions of Section
   9.15 of the Loan Agreement, Borrower will pay all out-of-pocket
   expenses incurred by Lender in connection with the preparation of
   this Amendment and of the other Financing Agreements, including,
   all amendments, supplements or modifications hereafter made to any
   of the foregoing after the date of this Amendment, and the closing
   of the transactions contemplated herein and therein, including,
   without limitation, the reasonable fees and expenses of counsel for
   Lender.  In addition, Borrower agrees to pay all documentary stamp
   taxes, intangible taxes, filing or recording fees required in
   connection with the borrowings hereunder and creating, perfecting
   and preserving Lender's security interest in the Collateral.

3. MISCELLANEOUS

3.1 WAIVER

The rights and remedies of Payee under this Note shall be
cumulative and not alternative. No waiver by Payee of any right or

any right, power or privilege under this Note will operate as a
waiver of such right, power or privilege and no single or partial
exercise of any such right, power or privilege by Payee will
preclude any other or further exercise of such right, power or
privilege or the exercise of any other right, power or privilege.
To the maximum extent permitted by applicable law, (a) no claim or
right of Payee arising out of this Note can be discharged by 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

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.

                   surety agreement (in addition to this Non-
                   Recourse Guaranty), pledge, assignment, or
                   other security for any of the obligations of
                   Payor under the Promissory Notes.

    The Guarantor waives notice of presentment, demand, protest

5.  The liability of the Guarantor under this Non-Recourse
Guaranty is absolute but is limited to its non-recourse nature as
provided in Section 3 hereof, without regard to the liability of
any other person, and shall not in any manner be affected by reason
of any action taken by the Payee, which action or inaction is
herein consented and agreed to, nor by the partial or complete
unenforceability or invalidity of any other guaranty or surety
agreement, pledge, assignment or other security of any of the
obligations of Payor to Payee under the Promissory Notes.  No delay
in making demand on the Guarantor for satisfaction of its liability
hereunder shall prejudice the Payee's right to enforce such
satisfaction.  All of the Payee's rights and remedies hereunder
shall be cumulative and any failure of the Payee to exercise any
right hereunder shall not be construed as a waiver of the right to
exercise the same or any other right at any time, and from time to
time, thereafter.

     To secure the payment of all obligations owing pursuant to a
Non-Recourse Guaranty dated as of May 27, 1999 executed by the
Mortgagor in favor of the Mortgagee (the "Guaranty"), the Mortgagor
does MORTGAGE and WARRANT to Mortgagee, its successors and assigns,
the land situated in the Township of Brownstown, County of Wayne
and State of Michigan, described on Exhibit A attached hereto and
incorporated herein by reference, together with all buildings and
improvements now or hereafter upon said land or any part thereof,
and all heretofore or hereafter vacated alleys and streets abutting
said land; and together with all licenses and permits to operate
the building thereon, all fixtures now or hereafter installed for
use in the operation of the building or buildings now or hereafter
on said land, including, but not limited to, all lighting, heating,
cooling, ventilating, air conditioning, plumbing, sprinkling,
electrical systems, and the fixtures pertaining thereto owned by
Mortgagor, all of which fixtures shall be deemed to be part of the
land (except for all tangible and intangible assets used in
connection with the business of the Mortgagor and its affiliates,
or any of them, including, without limitation, all permits and
licenses to operate such business, and all trade fixtures of
Mortgagor or its affiliates); and together with all the rents and

tenements, hereditaments, easements, and appurtenances (herein
called the "Mortgaged Premises").  The Mortgagee hereby disclaims
any interest in any other collateral or property of Mortgagor or
any of its affiliates.

     Mortgagor does hereby covenant and warrant as follows:

     FIRST:  Mortgagor shall pay all amounts due and owing
under the Guaranty and shall pay all other amounts provided herein
according to the terms of the Guaranty and this Mortgage.


<PAGE>
     SECOND: At the time of the execution and delivery of this
Mortgage, Mortgagor is well and truly seized of the Mortgaged
Premises in fee simple, free of all liens and encumbrances
whatsoever except for (i) real estate taxes and assessments not yet
due and payable, (ii) covenants, restrictions, easements,
reservations and agreements of record, (iii) rights of the public
to streets, roads and alleys lying within the boundaries of the
Mortgaged Premises, (iv) the state of facts an accurate survey may
disclose, and (v) such minor encroachments or encumbrances as do
not materially interfere with the development of the Mortgaged
Premises for its contemplated uses, and Mortgagor will forever
warrant and defend the same against any and all claims whatever,
and the lien created hereby is and will be kept a first lien upon
the Mortgaged Premises and every part thereof.

     THIRD:   Mortgagor shall pay before the same becomes
delinquent all taxes, assessments and other charges which might
become a lien upon the Mortgaged Premises prior to this Mortgage.

<PAGE>
Should default be made in the payment of any such taxes,
assessments or other charges, Mortgagee may, at its option, but
without any obligation on its part to do so, obtain pay such taxes,
assessments or other charges, and all amounts so expended by
Mortgagee shall be secured hereby and shall bear interest from the
date of expenditure at the rate of five percent (5%) per annum
until repaid by Mortgagor.

     FOURTH:   The occurrence of any of the following events shall
be deemed an "Event of Default" hereunder:  (i) default in making
payment when due of any amount owing under the Guaranty, or (ii)
default in making payment when due of any other sums provided
herein, or (iii) default in the performance of any covenant or
condition provided herein and the continuance thereof for 30 days
after notice of such default has been given by Mortgagee.  Upon the
occurrence of an Event of Default, Mortgagee may at any time
thereafter, declare the principal balance of the indebtedness
secured hereby, together with interest thereon, to be due and
payable immediately.

     FIFTH:   Upon any foreclosure sale of the Mortgaged
Premises, the same may be sold either as a whole or in parcels, as
Mortgagee may elect, and if in parcels, the same may be divided as
Mortgagee may elect and, at the election of Mortgagee may be
offered first in parcels and then as a whole, that offer producing
the highest price for the entire property to prevail, any law,
statutory or otherwise, to the contrary notwithstanding, and
Mortgagor hereby waives the right to require any such sale to be
made in parcels or the right to select such parcels.

     SIXTH:   Each and every of the rights, remedies and benefits
provided to Mortgagee herein shall be cumulative and shall not be
exclusive of any other of said rights, remedies or benefits, or of
any other rights, remedies or benefits allowed by law.  Any waiver
by Mortgagee of any default shall not constitute a waiver of any
similar or other default.


<PAGE>
     SEVENTH:  All of the covenants and conditions hereof shall run
with the land and shall be binding upon the successors and assigns
of Mortgagor, and shall inure to the benefit of the successors and
assigns of Mortgagee.  Any reference herein to "Mortgagee" shall
include the successors and assigns of Mortgagee.

     EIGHTH:   All notices given hereunder shall be in writing,
shall be effective when received and shall be sent to Mortgagor or
Mortgagee at their respective addresses first above written unless
another address is designated by notice to the other party in
writing.

     NINTH:    The rights and remedies under this Mortgage are

     upon the Collateral (as defined in the Loan Agreement), or any

<PAGE>

<PAGE>
     therein or thereto.  Each of the undersigned hereby disclaims any
     interest in any other Collateral or property of Borrower or any
     affiliate.
     2.   Each of the undersigned represents and warrants that the
     amount of the Notes outstanding on the date hereof is as follows:

          (iii)  $1,500,000 Note payable to Thomas P.
                 Sullivan Living Trust (Exhibit C);
     and that none of the undersigned shall, directly or indirectly, (A)

     create additional indebtedness or obligations of Borrower to the
     undersigned at any time hereafter, (B) amend, modify, alter or

     guarantee described in Section 3.2 of the Stock Purchase Agreement
     in respect of Chemical Conservation of Georgia, Inc. and Chemical
     Conservation Corporation, without the prior consent of Lender in
     its discretion.
     3.   So long as no Event of Default  or event which with the
     passage of time, giving of notice, or both, would constitute an
     Event of Default, shall have occurred and be continuing under the
     Loan Agreement, or in Lender's sole determination, if the payment
     to the undersigned of amounts permitted below would result in an
     Event of Default (notice of any of the foregoing is referred to as
     a Default Notice), Borrower may pay and, until Lender gives the
     undersigned written notice of the occurrence of an Event of
     Default, the undersigned may accept from the Borrower, the
     regularly scheduled payments of principal, together with accrued
     interest thereon, on the Notes when, and in the amounts, set forth
     in each respective Note.  Such payments shall exclude, without
     limitation, (a) prepayments (unless Lender has given its prior
     written consent in its sole discretion), (b) non-mandatory
     payments, (c) any payments pursuant to acceleration or pursuant to
     claims of breach or pursuant to claims to acquire any of the Notes
     or otherwise, or (d) any payments by virtue of setoff against any
     obligation of the undersigned, any of them, or their affiliates to
     indemnify or make payments to the Borrower or its affiliates,
     including, without limitation, obligations due the Borrower under
     those certain Stock Purchase Agreements among the undersigned, the
     Borrower, and Chem-Met Services, Inc., and Chemical Conservation of
     Georgia, Inc., and Chemical Conservation Corporation, respectively
     (the "Stock Purchase Agreements").  From and after the giving of
     Default Notice to an undersigned, unless and until the Event of
     Default or other event giving rise to a Default Notice in question
     is cured or waived by Lender (without implying any obligation on
     the part of Lender to permit a cure of or to waive any such Event
     of Default or other event), no further payments of principal or
     interest shall be made to any of the undersigned unless and until
     all Obligations have been paid in full and all Financing Agreements
     have been terminated, and unless Lender, in its sole discretion,
     gives its prior written consent, payments on the Subordinated Debt
     which accrued but were unpaid during any period commencing upon the
     giving of a Default Notice will not be permitted to be paid
     notwithstanding that a cure or waiver occurs (subject as
     aforesaid).  Notwithstanding any rights or remedies available to
     any of the undersigned under any of the respective Notes, the Stock
     Purchase Agreements, applicable law or otherwise, unless and until
     the indefeasible satisfaction in full of all the Obligations, none
     of the undersigned shall, directly or indirectly, seek to collect

<PAGE>

<PAGE>
     from Borrower, or exercise rights or remedies upon an event of
     default under the Notes, or any other payment in respect of
     Subordinated Debt, including, without limitation, filing an action
     to foreclose upon the Michigan Real Estate, filing a lis pendens
     against the Real Property, or any other judicial or non-judicial
     remedy, except that: (a) upon an event of default under the Notes,
     or any of them, or any other document evidencing the Subordinated
     Debt, the undersigned, as applicable, may declare Borrower to be in
     default under the respective Note(s) and accelerate the respective
     portion thereof, (b) any of the undersigned may defend the validity
     of its claims against the Borrower, and (c) any of the undersigned
     may file a proof of claim with respect to its claims against the
     Borrower, in a manner consistent with the terms of this Agreement.
     4.   Should any payment, distribution or security or proceeds
     thereof be received by any of the undersigned upon or with respect
     to the Subordinated Debt prior to the satisfaction of the
     Obligations, the applicable person or entity shall, except as
     provided in paragraph 3, forthwith deliver the same to the Lender
     in the form received (except for indorsement or assignment by the
     undersigned where required by the Lender), for application in
     accordance with the Loan Agreement, and, until so delivered, the
     same shall be held in trust by the undersigned as the property of
     the Lender.
     5.   In the event of any receivership, insolvency, bankruptcy,
     assignment for the benefit of creditors, readjustment of
     indebtedness, composition, reorganization, whether or not pursuant
     to bankruptcy laws, sale of all or substantially all of the assets,
     dissolution, winding up, liquidation, or any other marshalling of
     the assets and liabilities of the Borrower, regardless of whether
     Lender has given any of the undersigned a Default Notice, any
     payment or distribution of assets of the Borrower of any kind of
     character, whether in cash, securities or other property, which
     would otherwise be payable to or deliverable upon or with respect
     to the Subordinated Debt shall be paid or delivered directly to the
     Lender for application in accordance with the Loan Agreement until
     all Obligations shall have been fully paid and satisfied.  The
     Lender shall have the right to enforce, collect and receive every
     such payment or distribution and give acquittance therefor, and the
     Lender is hereby authorized, as attorney in fact for the
     undersigned, to vote and prove the respective indebtedness of the
     Borrower to the undersigned in any of the above described
     proceedings or in any meeting of creditors of the Borrower.
     6.   None of the undersigned shall assign, transfer,
     hypothecate or dispose of the Subordinated Debt or any claim it has
     or may have against the Borrower, while any of the Obligations
     remains unpaid, without the prior consent of the Lender.  The
     Notes, and any other instrument at any time evidencing the
     Subordinated Debt, or any portion thereof, shall be permanently
     marked on its face with a legend conspicuously indicating that
     payment thereof is subordinate in right of payment to the
     Obligations to the extent provided for herein and subject to the
     terms and conditions of this Agreement, and after being so marked
     certified copies thereof shall be delivered to Lender.  In the
     event any legend or endorsement is omitted, Lender or any of its
     officers or employees, are hereby irrevocably authorized on behalf
     of the undersigned to make the same.  No specific legend, further
     assignment or endorsement or delivery of notes, guarantees or
     instruments shall be necessary to subject any Subordinated Debt to
     the subordination thereof contained in this Agreement.
     7.   THIS AGREEMENT SHALL BE CONTINUING AND IRREVOCABLE SO LONG
     AS THE OBLIGATIONS HAVE NOT BEEN PAID IN FULL.  LENDER, AT ANY TIME
     AND FROM TIME TO TIME, MAY AMEND, MODIFY OR SUPPLEMENT THE FINANCING
     AGREEMENTS, INCREASE, RENEW OR EXTEND THE OBLIGATIONS, OR ANY OF
     THEM, OR OTHERWISE ENTER INTO SUCH AGREEMENTS WITH THE BORROWER AS

     OTHERWISE DEAL WITH ANY SECURITY, OR MAY RELEASE ANY BALANCE OF FUNDS
     OF THE BORROWER, WITH LENDER, WITHOUT NOTICE TO THE UNDERSIGNED AND
     WITHOUT IN ANY WAY IMPAIRING OR AFFECTING THIS AGREEMENT.
     8.   The Lender's delay in or failure to exercise any right or
     remedy shall not be deemed a waiver of any obligation of any of the
     undersigned or right of the Lender.  This Agreement may be
     modified, and any of the Lender's rights hereunder waived, only by
     agreement in writing signed by the Lender.
     9.   This Agreement shall inure to the benefit of the Lender,
     its successors and assigns and bind the respective heirs, legatees,
     personal representatives, successors and assigns of the
     undersigned.

           PERMA-FIX ENVIRONMENTAL COMPLETES ACQUISITION OF
          INDUSTRIAL WASTE TREATMENT COMPANIES WITH COMBINED
                   REVENUES OF MORE THAN $22 MILLION
               * Acquisition Is Accretive To Earnings
               * Pro-forma Annualized Revenues To Exceed $55 Million

Atlanta, GA  June 3, 1999   Perma-Fix Environmental Services, Inc.
(NASDAQ: PESI) (GERMANY: PES.BE) and its CEO, Dr. Louis F. Centofanti
announced today that it has completed the previously announced
acquisition of Chemical Conservation Corporation, Chemical Conservation
of Georgia, Inc. and Chem-Met Services, Inc. collectively referred to as
"Chem-Con." The combined purchase price of this acquisition totaled $8.7
million, with the consideration paid in the form of cash, notes and
common stock.

Chem-Con has more than 30 years of experience and proven expertise
in the waste industry and operates waste treatment facilities in Orlando,
Florida; Valdosta, Georgia; and Detroit, Michigan. For the year ended
September 30, 1998, Chem-Con had combined revenues of approximately $22
million and net income of $480,000.  The acquisition of Chem-Con is of
strategic importance to the continued growth of Perma-Fix and, including
Chem-Con revenues for a full twelve months, will result in revenue growth
to an annualized run-rate of more than approximately $55 million.  In
addition, the acquisition significantly expands the Company's presence
into several new major markets and geographic locations.   Perma-Fix
currently operates waste treatment facilities in Gainesville, Florida;
Ft. Lauderdale, Florida; Dayton, Ohio; and Tulsa, Oklahoma.

Chem-Con's revenues are principally generated from the collection,
treatment, and recycling of industrial and hazardous waste, including
waste oils, water and miscellaneous solid waste. Chemical Conservation
Corporation operates a permitted treatment and storage facility and
transfer station that also serves as the base for a private trucking
fleet; Chemical Conservation of Georgia, Inc. treats hazardous waste
and recycles solvents; and Chem-Met Services, Inc. treats and stabilizes
inorganic wastes and maintains a government services division that is
focused principally on the Defense Revitalization and Marketing Services
(DRMS) market.  Perma-Fix will utilize this established government
services division as a platform to further enhance its current and future
governmental initiatives. Perma-Fix will immediately capitalize on new
growth opportunities by incorporating the use of its proprietary Perma-
Fix I and patent-pending Perma-Fix II processes at these facilities.

Commenting on the acquisition, Dr. Louis Centofanti, Chairman and
Chief Executive Officer commented, "The acquisition significantly expands
the size of our market, increases our geographic presence and represents
a strategic milestone in the growth of our Company.  In addition, the
acquisition of Chem-Con is accretive to our earnings and will positively
impact our earnings per share.  We will immediately capitalize on the use
of our proprietary technologies at these new locations, towards
establishing a dominant position in the waste treatment industry. Chem-
Con is excellently managed, and experiencing growth, particularly within
its government services division, which focuses on the Department of
Defense (DOD). Their established presence as a provider of waste
treatment services to the government significantly expands our own
capabilities in this area, and will compliment our efforts to provide
hazardous waste treatment services to the U.S. Departments of Defense and
Energy."

Tom Sullivan, principal owner and President of Chem-Con, who will
join the Perma-Fix Board, commented that, "I am excited to be joining
forces with Perma-Fix. The combination of Perma-Fix and Chem-Con, as a
larger entity, will create a new powerful, and highly competitive force
in the environmental industry."

Perma-Fix Environmental Services, Inc. provides unique hazardous,
mixed and industrial waste management services, along with environmental
engineering and consulting services.   The Perma-Fix Process is a
proprietary mobile treatment technology that converts hazardous waste
into a non-hazardous material. The process is simple, safe, create little
or no volume increase and is the most cost-effective option on the market
today for the cleanup of mixed radioactive waste.  Perma-Fix is widely
recognized for meeting customer needs with technologically advanced
