Item 5.   Other Events.

Sale of Series 5 Class E Convertible Preferred Stock.

     On or about July 14, 1997, Perma-Fix Environmental Services,
Inc. (the "Company") issued to the Infinity Fund, L.P. ("Infinity"),
350 shares of newly-created Series 5 Class E Convertible Preferred
Stock, par value $.001 per share ("Series 5 Preferred"), at a price
of $1,000 per share, for an aggregate sales price of $350,000.  The
sale to Infinity was made in a private placement under Rule 506 of
Regulation D under the Securities Acts of 1933, as amended, pursuant
to the terms of a Subscription and Purchase Agreement, dated July 7,
1997, between the Company and Infinity ("Subscription Agreement").
The Company intends to utilize the proceeds received on the sale of
Series 5 Preferred for the payment of debt and general working
capital.
 
     The Series 5 Preferred has a liquidation preference over the
Company's common stock, par value $.001 per share ("Common Stock"),
equal to $1,000 consideration per outstanding share of Series 5
Preferred (the "Liquidation Value"), plus an amount equal to all
unpaid dividends accrued thereon.  The Series 5 Preferred accrues
dividends on a cumulative basis at a rate of four percent (4%) per
annum of the Liquidation Value ("Dividend Rate"), and is payable
semi-annually when and as declared by the Board of Directors.  No
dividends or other distributions may be paid or declared or set
aside for payment on the Company's Common Stock until all accrued
and unpaid dividends on all outstanding shares of Series 5 Preferred
have been paid or set aside for payment.  Dividends may be paid, at
the option of the Company, in the form of cash or Common Stock of
the Company.  If the Company pays dividends in Common Stock, such
is payable in the number of shares of Common Stock equal to the
product of (a) the quotient of (i) the Dividend Rate divided by (ii)
the average of the closing bid quotation of the Common Stock as
reported on the NASDAQ for the five trading days immediately prior to
the date the dividend is declared, multiplied by (b) a fraction,
the numerator of which is the number of days elapsed during the
period for which the dividend is to be paid and the denominator of
which is 365.  

     The holder of the Series 5 Preferred may convert into Common
Stock up to 175 shares of the Series 5 Preferred on and after
November 3, 1997, and the remaining 175 shares of the Series 5
Preferred on and after December 3, 1997.  The conversion price per
share is the lesser of (a) the product of the average closing bid
quotation for the five (5) trading days immediately preceding the
conversion date multiplied by 80% or (b) $1.6875. The minimum 
conversion price is $.75, which minimum will be eliminated from and 
after September 6, 1998.  If the average closing bid quotation for the 
five trading days immediately preceding the conversion of the Series 5 
Preferred equals or exceeds $2.11, the holder will have the right to 
convert the Series 5 Preferred into approximately 207,400 shares of 
Common Stock.  The Company will have the option to redeem the shares 
of Series 5 Preferred (a) between July 14, 1998, and July 13, 2001, 
at a redemption price of $1,300 per share if at any time the average 
closing bid price of the Common Stock for ten consecutive trading days 
is in excess of $4.00, and (b) after July 13, 2001, at a redemption 
price of $1,000 per share. The holder of the Series 5 Preferred will 
have the option to convert the Series 5 Preferred prior to redemption 
by the Company.

     On June 30, 1997, the Company entered into a Stock Purchase

currently the President, Chief Executive Officer, Chairman of the
Board, and Director of the Company, whereby the Company sold, and
Dr. Centofanti purchased, 24,381 shares of the Company's Common
Stock.  The sale to Dr. Centofanti was made in a private placement
under Rule 506 of Regulation D under the Securities Act of 1933,
as amended.  The purchase price was $1.6406 per share representing
75% of the $2.1875 closing bid price of the Common Stock as quoted
on the NASDAQ on the date that Dr. Centofanti notified the Company
of his desire to purchase such shares.  Pursuant to the terms of the
Centofanti Agreement, Dr. Centofanti paid the Company the aggregate 
purchase price of $40,000 for the 24,381 shares of Common Stock.  The

3.   Representations, Warranties and Covenants of Subscriber.  The
Subscriber hereby represents, warrants and covenants to the Company
as follows:


                               -3-
<PAGE>
     3.1  Investment Intent.  The Subscriber represents and
          warrants that the Series 5 Preferred Stock is being, and
          any underlying Conversion Shares will be,  purchased or
          acquired solely for the Subscriber's own account, for
          investment purposes only and not with a view toward the
          distribution or resale to others.  The Subscriber
          acknowledges, understands and appreciates that the Series
          5 Preferred Stock has not been registered under the
          Securities Act by reason of a claimed exemption under the
          provisions of the Securities Act which depends, in large
          part, upon the Subscriber's representations as to
          investment invention, investor status, and related and
          other matters set forth herein.  Subscriber understands
          that, in the view of the United States Securities and
          Exchange Commission (the "SEC"), among other things, a
          purchase now with an intent to distribute or resell would
          represent a purchase and acquisition with an intent
          inconsistent with its representation to the Company, and
          the SEC might regard such a transfer as a deferred sale
          for which the registration exemption is not available.

     3.2  Certain Risk.  The Subscriber recognizes that the
          purchase of the Series 5 Preferred Stock involves a high
          degree of risk in that (a) the Company has sustained
          losses through March 31, 1997, from its operations, and
          may require substantial funds in addition to the proceeds
          of this private placement; (b) that the Company has a
          substantial accumulated deficit; (c) an investment in the
          Company is highly speculative and only investors who can
          afford the loss of their entire investment should
          consider investing in the Company and the Series 5
          Preferred Stock; (d) an investor may not be able to
          liquidate his investment; (e) transferability of the
          Series 5 Preferred Stock is extremely limited; (f) in the
          event of a disposition an investor could sustain the loss
          of his entire investment; (g) the Series 5 Preferred
          Stock represents non-voting equity securities, and the
          right to convert into and purchase shares of voting
          equity securities in a corporate entity that has an
          accumulated deficit; (h) no return on investment, whether
          through distributions, appreciation, transferability or
          otherwise, and no performance by, through or of the
          Company, has been promised, assured, represented or
          warranted by the Company, or by any director, officer,
          employee, agent or representative thereof; and, (i) while
          the Common Stock is presently quoted and traded on the
          Boston Stock Exchange and the Nasdaq SmallCap Market and
          while the Subscriber is a beneficiary of certain
          registration rights provided herein, the Series 5
          Preferred Stock subscribed for and that is purchased
          under this Agreement  and the Conversion Shares (i) are
          not registered under applicable federal or state
          securities laws, and thus may not be sold, conveyed,
          assigned or transferred unless registered under such laws
          or unless an exemption from registration is available
          under such laws, as more fully described herein, and (ii)
          the Series 5 Preferred Stock subscribed for and that is
          to be purchased under this Agreement is not quoted,

                                -4-
<PAGE>
          traded or listed for trading or quotation on the NASDAQ,
          or any other organized market or quotation system, and
          there is therefore no present public or other market for
          the Series 5 Preferred Stock, nor can there be any
          assurance that the Common Stock of the Company will
          continue to be quoted, traded or listed for trading or
          quotation on the Boston Stock Exchange or the Nasdaq
          SmallCap Market or on any other organized market or
          quotation system.

     3.3  Prior Investment Experience.  The Subscriber acknowledges
          that it has prior investment experience, including
          investment in non-listed and non-registered securities,
          or has employed the services of an investment advisor,
          attorney or accountant to read all of the documents
          furnished or made available by the Company to it and to
          evaluate the merits and risks of such an investment on
          its behalf, and that it recognizes the highly speculative
          nature of this investment.

     3.4  No Review by the SEC.  The Subscriber hereby acknowledges
          that this offering of the Series 5 Preferred Stock has
          not been reviewed by the SEC because this private
          placement is intended to be a nonpublic offering pursuant
          to Sections 4(2) and/or 3(b) of the Securities Act and/or
          Regulation D promulgated under the Securities Act.

     3.5  Not Registered.  The Subscriber understands that the
          Series 5 Preferred Stock and the Conversion Shares have
          not been registered under the Securities Act by reason of
          a claimed exemption under the provisions of the
          Securities Act which depends, in part, upon the
          Subscriber's investment intention.  In this connection,
          the Subscriber understands that it is the position of the
          SEC that the statutory basis for such exemption would not
          be present if its representation merely meant that its
          present intention was to hold such securities for a short
          period, such as the capital gains period of tax statutes,
          for a deferred sale, for a market rise (assuming that a
          market develops), or for any other fixed period.

     3.6  No Public Market.  The Subscriber understands that there
          is no public market for the Series 5 Preferred Stock. 
          The Subscriber understands that although there is
          presently a public market for the Common Stock, including
          the Common Stock issuable upon conversion of the Series
          5 Preferred Stock, Rule 144 (the "Rule") promulgated
          under the Securities Act requires, among other
          conditions, a one-year holding period following full
          payment of the consideration therefor prior to the resale
          (in limited amounts) of securities acquired in a
          nonpublic offering without having to satisfy the
          registration requirements under the Securities Act.  The
          Subscriber understands that the Company makes no
          representation or warranty regarding its fulfillment in
          the future of any reporting requirements under the
          Exchange Act, or its dissemination to the public of any
          current financial or other information concerning the
          Company, as is required by the Rule as one of the
          conditions of its availability.  The Subscriber

                              -5-
<PAGE>
          understands and hereby acknowledges that the Company is
          under no obligation to register the Series 5 Preferred
          Stock or the Conversion Shares under the Securities Act,
          except as set forth in Section 5 hereof.  The Subscriber
          agrees to hold the Company and its directors, officers
          and controlling persons and their respective heirs,
          representatives, successors and assigns harmless and to
          indemnify them against all liabilities, costs and
          expenses incurred by them as a result of any
          misrepresentation made by the Subscriber contained herein
          or any sale or distribution by the Subscriber in
          violation of the Securities Act or any applicable state
          securities or "blue sky" laws (collectively, "Securities
          Laws").

     3.7  Sophisticated Investor.  That (a) the Subscriber is an
          "accredited investor," as such term is defined in Rule
          501 of Regulation D promulgated under the Securities Act,
          and has total assets in excess of $5,000,000; (b) the
          Subscriber has adequate means of providing for the
          Subscriber's current financial needs and possible
          contingencies and has no need for liquidity of the
          Subscriber's investment in the Series 5 Preferred Stock;
          (c) the Subscriber is able to bear the economic risks
          inherent in an investment in the Series 5 Preferred Stock
          and that an important consideration bearing on its
          ability to bear the economic risk of the purchase of
          Series 5 Preferred Stock is whether the Subscriber can
          afford a complete loss of the Subscriber's investment in
          the Series 5 Preferred Stock and the Subscriber
          represents and warrants that the Subscriber can afford
          such a complete loss; and (d) the Subscriber has such
          knowledge and experience in business, financial,
          investment and banking matters (including, but not
          limited to, investments in restricted, non-listed and
          non-registered securities) that the Subscriber is capable
          of evaluating the merits, risks and advisability of an
          investment in the Series 5 Preferred Stock.

     3.8  SEC Filing.  The Subscriber acknowledges that it has been
          previously furnished with true and complete copies of the
          following documents which have been filed with the SEC
          pursuant to Sections 13(a), 14(a), 14(c) or 15(d) of the
          Exchange Act since January 1, 1997, and that such have
          been furnished to the Subscriber a reasonable time prior
          to the date hereof: (a) the Company's Form 10-K for the
          year ended December 31, 1996; (b) the Company's Form 10-Q
          for the quarter ended March 31, 1997, and (c) the
          Company's Form 8-K, date of event reported: June 11,
          1997, as amended by the Company's Form 8-K/A, dated
          June 25, 1997.

     3.9  Documents, Information and Access.  The Subscriber's
          decision to purchase the Series 5 Preferred Stock is not
          based on any promotional, marketing or sales materials,
          and the Subscriber and its representatives have been
          afforded, prior to purchase thereof, the opportunity to
          ask questions of, and to receive answers from, the
          Company and its management, and has had access to all

                              -6-
<PAGE>
          documents and information which Subscriber deems material
          to an investment decision with respect to the purchase of
          Series 5 Preferred Stock hereunder.

     3.10 No Registration, Review or Approval.  The Subscriber
          acknowledges and understands that the private offering
          and sale of Series 5 Preferred Stock pursuant to this
          Agreement has not been reviewed or approved by the SEC or
          by any state securities commission, authority or agency,
          and is not registered under the Securities Laws.  The
          Subscriber acknowledges, understands and agrees that the
          Series 5 Preferred Stock is being offered and sold
          hereunder pursuant to (i) a private placement exemption
          to the registration provisions of the Securities Act
          pursuant to Section 3(b) and/or Section 4(2) of such
          Securities Act and/or Regulation D promulgated under the
          Securities Act) and (ii) a similar exemption to the
          registration provisions of applicable state securities
          laws.

     3.11 Transfer Restrictions.  That Subscriber will not transfer
          any Series 5 Preferred Stock purchased under this
          Agreement or any Conversion Shares acquired upon
          conversion of the Series 5 Preferred Stock unless such
          Series 5 Preferred Stock or the Conversion Shares,
          whichever is applicable, is registered under the
          Securities Laws, or unless an exemption is available
          under such Securities Laws, and the Company may, if it
          chooses, where an exemption from registration is claimed
          by such Subscriber, condition any transfer of Series 5
          Preferred Stock or Conversion Shares out of the
          Subscriber's name on an opinion of the Company's counsel,
          to the effect that the proposed transfer is being
          effected in accordance with, and does not violate, an
          applicable exemption from registration under the
          Securities Laws, or an opinion of counsel to the
          Subscriber, which opinion is satisfactory to the Company,
          to the effect that registration under the Securities Act
          is not required in connection with such sale or transfer
          and the reasons therefor.

     3.12 Trading Activity.  The Subscriber expressly agrees that
          until such time that it has sold all of the Series 5
          Preferred Stock and/or all of the Conversion Shares that
          it shall not, directly or indirectly, through an
          affiliate (as that term is defined under Rule 405
          promulgated under the Securities Act) or by, with or
          through an unrelated third party or entity, whether or
          not pursuant to a written or oral understanding,
          agreement, arrangement, scheme, or artifice of nature
          whatsoever, engage in the short selling of the Company's

                              -7-
<PAGE>
          Common Stock or any other equity securities of the
          Company, whether now existing or hereafter issued, or
          engage in any other activity of any nature whatsoever
          that has the same effect as a short sale, or is a de
          facto or de jure short sale, of the Company's Common
          Stock or any other equity security of the Company,
          whether now existing or hereafter issued, including, but
          not limited to, the sale of any rights pursuant to any
          understanding, agreement, arrangement, scheme or artifice
          of any nature whatsoever, whether oral or in writing,
          relative to the Company's Common Stock or any other
          equity securities of the Company whether now existing or
          hereafter created.  The Subscriber agrees that it will
          not engage, and will cause its affiliates not to engage,
          in any activity designed to reduce the price of the
          Company's Common Stock, as quoted on the Boston Stock
          Exchange or the NASDAQ, in connection with the
          Subscriber's conversion of any of the Series 5 Preferred
          Stock.  The Subscriber agrees to refrain, and cause its
          affiliates to refrain, from engaging in, or inducing
          others to engage in, any activity relating to the Company
          or Common Stock of the Company that is proscribed under
          Regulation M promulgated under the Exchange Act.

     3.13 Reliance.  The Subscriber understands and acknowledges
          that the Company is relying upon all of the
          representations, warranties, covenants, understandings,
          acknowledgements and agreements contained in this
          Agreement in determining whether to accept this
          subscription and to sell and issue the Series 5 Preferred
          Stock to the Subscriber.

     3.14 Accuracy or Representations and Warranties.  All of the
          representations, warranties, understandings and
          acknowledgments that Subscriber has made herein are true
          and correct in all material respects as of the date of
          execution hereof.  The Subscriber will perform and comply
          fully in all material respects with all covenants and
          agreements set forth herein, and the Subscriber covenants
          and agrees that until the acceptance of this Agreement by
          the Company, the Subscriber shall inform the Company
          immediately in writing of any changes in any of the
          representations or warranties provided or contained
          herein.

     3.15 Indemnity.  The Subscriber hereby agrees to indemnify and
          hold harmless the Company, and the Company's successors
          and assigns, from, against and in all respects of any
          demands, claims, actions or causes of action,
          assessments, liabilities, losses, costs, damages,
          penalties, charges, fines or expenses (including, without
          limitation, interest, penalties, and attorney and
          accountants' fees, disbursements and expenses), arising
          out of or relating to any breach by Subscriber of any
          representations, warranty, covenant or agreement made by
          Subscriber in this Agreement.  Such right to
          indemnification shall be in addition to any and all other
          rights of the Company under this Agreement or otherwise,
          at law or in equity.

     3.16 Survival.  The Subscriber expressly acknowledges and
          agrees that all of its representations, warranties,
          agreements and covenants set forth in this Agreement
          shall be of the essence hereof and shall survive the
          execution, delivery and Closing of this Agreement, the
          sale and purchase of the Series 5 Preferred Stock, the
          conversion of the Series 5 Preferred Stock, and the sale
          of the Conversion Shares.

4.   Representations, Warranties and Covenants of the Company.  In
order to induce Subscriber to enter into this Agreement and to
purchase the Series 5 Preferred Stock, the Company hereby
represents, warrants and covenants to Subscriber as follows:

     4.1  Organization, Authority, Qualification.  The Company is
          a corporation duly incorporated, validly existing and in
          good standing under the laws of the State of Delaware. 
          The Company has full corporate power and authority to own
          and operate its properties and assets and to conduct and
          carry on its business as it is now being conducted and
          operated.

     4.2  Authorization.  The Company has full power and authority
          to execute and deliver this Agreement and to perform its
          obligations under and consummate the transactions
          contemplated by this Agreement.  Upon the execution of
          this Agreement by the Company and delivery of the Series
          5 Preferred Stock, this Agreement shall have been duly
          and validly executed and delivered by the Company and
          shall constitute the legal, valid and binding obligation
          of the Company, enforceable against the Company in
          accordance with its terms.

     4.3  Ownership of, and Title to, Securities.  The Series 5
          Preferred Stock to be purchased by the Subscriber is, and
          all Conversion Shares, when issued, will be, duly
          authorized, validly issued, fully paid and nonassessable
          shares of the capital stock of the Company, free of
          personal liability.  Upon consummation of the purchase of
          the Series 5 Preferred Stock (and upon the conversion of
          the Series 5 Preferred Stock, in whole or in part)
          pursuant to this Agreement, the Subscriber will own and
          acquire title to the Series 5 Preferred Stock (and the
          Conversion Shares) free and clear of any and all proxies,
          voting trusts, pledges, options, restrictions, or other
          legal or equitable encumbrance of any nature whatsoever
          (other than the restrictions on transfer due to
          Securities Laws or as otherwise provided for in this
          Agreement or the Certificate of Designation).

     4.4  Exemption from Registration.  The offer and sale of
          Series 5 Preferred Stock to the Subscriber in accordance
          with the terms and provisions of this Agreement is being
          effected in accordance with the Securities Act, pursuant
          to a private placement exemption to the registration
          provisions of the Act pursuant to Section 3(b) and/or
          4(2) of such Act and/or Regulation D promulgated under
          such Act, based on the representations, warranties and
          covenants made by the Subscriber contained in this
          Agreement.

     4.5  Use of Proceeds from this Offering.  The net proceeds
          from the sale of the Series 5 Preferred Stock are
          estimated to be approximately $345,000 after payment of
          legal fees and expenses of approximately $5,000, but
          prior to any fees and expenses relating to the
          registration of the Conversion Shares pursuant to the


                              -9-
<PAGE>
          terms of Section 5 hereof.  The Company intends to
          utilize the net proceeds to reduce outstanding debt and
          for general working capital.

5.   Registration Rights.  In order to induce the Subscriber to
enter into this Agreement and purchase the Series 5 Preferred Stock,
the Company hereby covenants and agrees to grant to the Subscriber
the rights set forth in this Section 5 with respect to the
registration of the Conversion Shares.

     5.1  Registration.  Subject to the terms of Section 5 hereof,
          the Company agrees that within thirty (30) days after the
          Closing Date, it shall prepare and file with the SEC, a
          registration statement on Form S-3 or equivalent form
          (the "Registration Statement") and such other documents,
          including a prospectus, as may be necessary in the
          opinion of counsel for the Company in order to comply
          with the provisions of the Securities Act, so as to
          permit a public offering and sale by the Subscriber of up
          to 200,000 shares of Common Stock issuable upon
          conversion of the Series 5 Preferred Stock, plus up to
          36,000 shares of Common Stock, if any, issuable as
          payment of dividends on the Series 5 Preferred Stock
          pursuant to the terms of the Series 5 Preferred Stock. 
          The Company shall use its reasonable efforts to cause
          such Registration Statement to become effective at the
          earliest possible date after filing.  In connection with
          the offering of such Common Stock registered pursuant to
          this Section 5, the Company shall take such reasonable
          actions, as it deems necessary, to qualify the Common
          Stock issuable upon conversion of the Series 5 Preferred
          Stock, plus the Common Stock issuable as payment of
          dividends on the Series 5 Preferred Stock, covered by
          such Registration Statement under such "blue sky" or
          other state securities laws for offer and sale as shall
          be reasonably necessary to permit the public offering and
          sale of such shares of Common Stock covered by such
          Registration Statement; provided, however, that the
          Company shall not be required (a) to qualify generally to
          do business in any jurisdiction where it would not
          otherwise be required to qualify but for this
          subparagraph, (b) to subject itself to taxation in any
          such jurisdiction, or (c) to consent to general service
          of process in any such jurisdiction.  It is expressly
          agreed that in no event are any registration rights being
          granted to the Series 5 Preferred Stock itself, but only
          with respect to up to 200,000 shares of the underlying
          Conversion Shares issuable upon exercise of the Series 5
          Preferred Stock, plus up to 36,000 shares of Common Stock
          that the Company may issue in payment of dividends on the
          Series 5 Preferred Stock.

     5.2  Current Registration Statement.  Once effective, the
          Company shall use its reasonable efforts to cause such
          Registration Statement filed hereunder to remain current
          and effective for a period of two (2) years or until the
          Conversion Shares covered by such Registration Statement
          are sold by the Subscriber, whichever is sooner.  The

                              -10-
<PAGE>
          Subscriber shall promptly provide all such information
          and materials and take all such action as may be required
          in order to permit the Company to comply with all
          applicable requirements of the SEC and to obtain any
          desired acceleration of the effective date of such
          registration statement.

     5.3  Other Provisions.  In connection with the offering of any
          Conversion Shares registered pursuant to this Section 5,
          the Company shall furnish to the Subscriber such number

          request in order to effect the offering and sale of the
          Conversion Shares to be offered and sold under such
          Registration Statement.  In connection with any offering
          of Conversion Shares registered pursuant to this Section
          5, the Company shall (a) furnish to the underwriters (if
          any), at the Company's expense, unlegended certificates
          representing ownership of the Conversion Shares sold
          under such Registration Statement in such denominations
          as requested and (b) instruct any transfer agent and
          registrar of the Conversion Shares sold under such
          Registration Statement to release immediately any stop
          transfer order, and to remove any restrictive legend,
          with respect to such Conversion Shares included in any
          registration becoming effective pursuant to this
          Agreement upon the sale of such shares by the Subscriber.

     5.4  Costs.  Subject to the immediately following sentence,
          the Company shall in all events pay and be responsible
          for all fees, expenses, costs and disbursements
          associated with the Registration Statement relating to
          the Conversion Shares under this Section 5, including
          filing fees, fees, costs and disbursements of any
          counsel, accountants and other consultants representing
          the Company in connection therewith.  Notwithstanding
          anything set forth herein to the contrary, Subscriber
          shall be responsible for and pay any and all underwriting
          discounts and commissions in connection with the sale of
          the Conversion Shares pursuant hereto or the Registration
          Statement and all fees of its legal counsel and other
          advisors retained in connection with reviewing such
          Registration Statement.

     5.5  Successors.  The Company will require any successor
          (whether direct or indirect, by purchase, merger,
          consolidation or otherwise) to all or substantially all
          of the business, properties, stock or assets of the
          Company, to expressly assume and agree to perform this
          Agreement in the same manner and to the same extent that
          the Company would be required to perform it if no such
          succession had taken place.

6.   Indemnification.

     6.1  By the Company.  Subject to the terms of this Section 6,
          the Company will indemnify and hold harmless the
          Subscriber, its directors and officers, and any
          underwriter (as defined in the Securities Act) for the


                             -11-
<PAGE>
          Subscriber and each person, if any, who controls the
          Subscriber or such underwriter within the meaning of the
          Act, from and against, and will reimburse the Subscriber
          and each such underwriter and controlling person with
          respect to, any and all loss, damage, liability, cost and
          expense to which such holder or any such underwriter or
          controlling person may become subject under the Act or
          otherwise, insofar as such losses, damages, liabilities,
          costs or expenses are caused by any untrue statement or
          alleged untrue statement of any material fact contained
          in the Registration Statement filed with the SEC pursuant
          to Section 5, any prospectus contained therein or any
          amendment or supplement 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, in light of the
          circumstances in which they were made not misleading;
          provided, however, that the Company will not be liable in
          any such case to the extent that any such loss, damage,
          liability, cost or expense arises out of, or is based
          upon, an untrue statement or alleged untrue statement or
          omission or alleged omission so made in conformity with
          information furnished by the Subscriber, such underwriter
          or such controlling person in writing specifically for
          use in the preparation thereof.

     6.2  By the Subscriber.  Subject to the terms of this Section
          6, the Subscriber will indemnify and hold harmless the
          Company, its directors and officers, any controlling
          person and any underwriter from and against, and will
          reimburse the Company, its directors and officers, any
          controlling person and any underwriter with respect to,
          any and all loss, damage, liability, cost or expense to
          which the Company or any controlling person and/or any
          underwriter may become subject under the Securities Act
          or otherwise, insofar as such losses, damages,
          liabilities, costs or expenses are caused by any untrue
          statement or alleged untrue statement of any material
          fact contained in such Registration Statement filed with
          the SEC pursuant to Section 5, any prospectus contained
          therein or any amendment or supplement 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, in light of the circumstances in which they were
          made, not misleading, in each case to the extent, but
          only to the extent, that such untrue statement or alleged
          untrue statement or omission or alleged omission was so
          made in reliance upon, and in strict conformity with,
          written information furnished by, or on behalf of, the
          Subscriber specifically for use in the preparation
          thereof.

     6.3  Procedure.  Promptly after receipt by an indemnified
          party pursuant to the provisions of Section 6.1 or 6.2 of
          notice of the commencement of any action involving the
          subject matter of the foregoing indemnity provisions,
          such indemnified party will, if a claim thereof is to be
          made against the indemnifying party pursuant to the
          provisions of Section 6.1 or 6.2, promptly notify the


                              -12-
<PAGE>
          indemnifying party of the commencement thereof; but the
          omission to so notify the indemnifying party will not
          relieve the indemnifying party from any liability which
          it may have to any indemnified party otherwise than
          hereunder.  In case such action is brought against any
          indemnified party and the indemnified party notifies the
          indemnifying party of the commencement thereof, the
          indemnifying party shall have the right to participate
          in, and, to the extent that it may wish, assume the
          defense thereof; or, if there is a conflict of interest
          which would prevent counsel for the indemnifying party
          from also representing the indemnified party, the
          indemnified parties have the right to select only one (1)
          separate counsel to participate in the defense of such
          action on behalf of all such indemnified parties.  After
          notice from the indemnifying parties to such indemnified
          party of the indemnifying parties' election so to assume
          the defense thereof, the indemnifying parties will not be
          liable to such indemnified parties pursuant to the
          provisions of said Section 6.1 or 6.2 for any legal or
          other expense subsequently incurred by such indemnified
          parties in connection with the defense thereof, other
          than reasonable costs of investigation, unless (a) the
          indemnified parties shall have employed counsel in
          accordance with the provisions of the preceding sentence;
          (b) the indemnifying parties shall not have employed
          counsel satisfactory to the indemnified parties to
          represent the indemnified parties within a reasonable
          time after the notice of the commencement of the action
          or (c) the indemnifying party has authorized the
          employment of counsel for the indemnified party at the
          expense of the indemnifying parties.

                   RESOLUTION OF THE BOARD OF DIRECTORS

         FIXING THE NUMBER AND DESIGNATING THE RIGHTS, PRIVILEGES,
               RESTRICTIONS AND CONDITIONS ATTACHING TO THE 
               SERIES 5 CLASS E CONVERTIBLE PREFERRED STOCK


     WHEREAS, the Corporation's capital includes preferred stock,
par value $.001 per share ("Preferred Stock"), which Preferred
Stock may be issued in one or more series by resolutions adopted by
the directors, and with the directors being entitled by resolution
to fix the number of shares in each series and to designate the
rights, designations, preferences and relative, participating,
optional or other special rights and privileges, and
qualifications, limitations or restrictions attaching to the shares
of each such series;

     WHEREAS, it is in the best interests of the Corporation for
the Board to create a new series from the Preferred Stock
designated as the Series 5 Class E Convertible Preferred Stock, par
value $.001 per share ("Series 5 Class E Preferred Stock");

     NOW, THEREFORE, BE IT RESOLVED, that the Series 5 Class E
Convertible Preferred Stock, par value $.001 (the "Series 5 Class
E Preferred Stock") of the Corporation shall consist of three
hundred fifty (350) shares and no more and shall be designated as
the Series 5 Class E Convertible Preferred Stock, and the
preferences, rights, privileges, restrictions and conditions
attaching to the Series 5 Class E Preferred Stock shall be as
follows:

Part 1 - Voting and Preemptive Rights.

1.1  Voting Rights.  Except as otherwise provided in Section
242(b)(2) of the General Corporation Law of the State of Delaware
(the "GCL"), the holders of the Series 5 Class E Preferred Stock
shall have no voting rights whatsoever.  To the extent that under
Section 242(b)(2) of the GCL the vote of the holders of the Series
5 Class E Preferred Stock, voting separately as a class or series
as applicable, is required to authorize a given action of the
Corporation, the affirmative vote or consent of the holders of at
least a majority of the shares of the Series 5 Class E Preferred
Stock represented at a duly held meeting at which a quorum is
present or by written consent of a majority of the shares of Series
5 Class E Preferred Stock (except as otherwise may be required
under the GCL) shall constitute the approval of such action by the
series.  To the extent that under Section 242(b)(2) of the GCL the
holders of the Series 5 Class E Preferred Stock are entitled to
vote on a matter, each share of the Series 5 Class E Preferred
Stock shall be entitled one (1) vote for each outstanding share of
Series 5 Class E Preferred Stock.  Holders of the Series 5 Class E


                               -2-
<PAGE>
Preferred Stock shall be entitled to notice of (and copies of proxy
materials and other information sent to stockholders) for all
shareholder meetings or written consents with respect to which they
would be entitled to vote, which notice would be provided pursuant
to the Corporation's bylaws and applicable statutes.  If the
holders of the Series 5 Class E Preferred Stock are required to
vote under Section 242(b)(2) of the GCL as a result of the number
of authorized shares of any such class or classes of stock being
increased or decreased, the number of authorized shares of any of
such class or classes of stock may be increased or decreased (but
not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of the
Corporation entitled to vote thereon, irrespective of the
provisions of Section 242(b)(2) of the GCL.

1.2  No Preemptive Rights.  The Series 5 Class E Preferred Stock
shall not give its holders any preemptive rights to acquire any
other securities issued by the Corporation at any time in the
future.

Part 2 - Liquidation Rights.

2.1  Liquidation.  If the Corporation shall be voluntarily or
involuntarily liquidated, dissolved or wound up at any time when
any shares of the Series 5 Class E Preferred Stock shall be
outstanding, the holders of the then outstanding Series 5 Class E
Preferred Stock shall be entitled to receive out of the assets of
the Corporation available for distribution to shareholders an
amount equal to $1,000 consideration per outstanding share of
Series 5 Class E Preferred Stock, and no more, plus an amount equal
to all unpaid dividends accrued thereon to the date of payment of
such distribution ("Liquidation Preference"), whether or not
declared by the Board of Directors, before any payment shall be
made or any assets distributed to the holders of the Corporation's
Common Stock.

2.2  Payment of Liquidation Preferences.  Subject to the provisions
of Part 6 hereof, all amounts to be paid as Liquidation Preference
to the holders of Series 5 Class E Preferred Stock, as provided in
this Part 2, shall be paid or set apart for payment before the
payment or setting apart for payment of any amount for, or the
distribution of any of the Corporation's property to the holders of
the Corporation's Common Stock, whether now or hereafter
authorized, in connection with such liquidation, dissolution or
winding up.

2.3  No Rights After Payment.  After the payment to the holders of
the shares of the Series 5 Class E Preferred Stock of the full
Liquidation Preference amounts provided for in this Part 2, the
holders of the Series 5 Class E Preferred Stock as such shall have
no right or claim to any of the remaining assets of the
Corporation.

2.4  Assets Insufficient to Pay Full Liquidation Preference.  In
the event that the assets of the Corporation available for
distribution to the holders of shares of the Series 5 Class E
Preferred Stock upon any dissolution, liquidation or winding up of
the Corporation, whether voluntary or involuntary, shall be

                              -3-
<PAGE>
insufficient to pay in full all amounts to which such holders are
entitled pursuant to this Part 2, no such distribution shall be
made on account of any shares of any other class or series of
Preferred Stock ranking on a parity with the shares of this Series
5 Class E Preferred Stock upon such dissolution, liquidation or
winding up unless proportionate distributive amounts shall be paid
on account of the shares of this Series 5 Class E Preferred Stock
and shares of such other class or series ranking on a parity with
the shares of this Series 5 Class E Preferred Stock, ratably, in
proportion to the full distributable amounts for which holders of
all such parity shares are respectively entitled upon such
dissolution, liquidation or winding up.

Part 3 - Dividends.

3.1  The holders of the Series 5 Class E Preferred Stock are
entitled to receive if, when and as declared by the Board of
Directors of the Corporation (the "Board") out of funds legally
available therefor, cumulative annual dividends, payable in cash or
Common Stock of the Corporation, par value $.001 per share (the
"Common Stock"),  or any combination thereof, at the Corporation's
election, at the rate of four percent (4%) per annum of the
Liquidation Value (as defined below) of each issued and outstanding
share of Series 5 Class E Preferred Stock (the "Dividend Rate"). 
The Liquidation Value of the Series 5 Class E Preferred Stock shall
be $1,000 per outstanding share of the Series 5 Class E Preferred
Stock (the "Liquidation Value").  The dividend is payable semi-
annually within seven (7) business days after each of December 31
and June 30 of each year, commencing December 31, 1997 (each, a
"Dividend Declaration Date").  Dividends shall be paid only with
respect to shares of Series 5 Class E Preferred Stock actually
issued and outstanding on a Dividend Declaration Date and to
holders of record of the Series 5 Class E Preferred Stock as of the
Dividend Declaration Date.  Dividends shall accrue from the first
day of the semi-annual period in which such dividend may be
payable, except with respect to the first semi-annual dividend
which shall accrue from the date of issuance of the Series 5 Class
E Preferred Stock.  In the event that the Corporation elects to pay
the accrued dividends due as of a Dividend Declaration Date on an
outstanding share of the Series 5 Class E Preferred Stock in Common
Stock of the Corporation, the holder of such share shall receive
that number of shares of Common Stock of the Corporation equal to
the product of (a) the quotient of (i) the Dividend Rate divided by
(ii) the average of the closing bid quotation of the Corporation's
Common Stock as reported on the National Association of Securities
Dealers Automated Quotation system ("NASDAQ"), or the average
closing sale price if listed on a national securities exchange, for
the five (5) trading days immediately prior to the Dividend
Declaration Date (the "Stock Dividend Price"), times (b) a
fraction, the numerator of which is the number of days elapsed
during the period for which the dividend is to be paid, and the
denominator of which is 365.  Dividends on the Series 5 Class E
Preferred Stock shall be cumulative, and no dividends or other
distributions shall be paid or declared or set aside for payment on
the Corporation's Common Stock until all accrued and unpaid
dividends on all outstanding shares of Series 5 Class E Preferred
Stock shall have been paid or declared and set aside for payment.


                              -4-
<PAGE>
Part 4 - Conversion.  The holders of the Series 5 Class E Preferred
Stock shall have rights to convert the shares of Series 5 Class E
Preferred Stock into shares of the Corporation's Common Stock, as
follows (the "Conversion Rights"):

4.1  Right to Convert.  The Series 5 Class E Preferred Stock shall
     be convertible into shares of Common Stock, as follows:

     4.1.1     Up to one hundred seventy-five (175) shares of
               Series 5 Class E Preferred Stock may be converted
               at the Conversion Price (as that term is defined in
               Section 4.2 below) at any time on or after November
               3, 1997; and,

     4.1.2     Up to an additional one hundred seventy-five (175)
               shares of Series 5 Class E Preferred Stock may be
               converted at the Conversion Price at any time on or
               after December 3, 1997.

4.2  Conversion Price.  Subject to the terms hereof, as used
     herein, the term Conversion Price per outstanding share of
     Series 5 Class E Preferred Stock shall be the product of the
     lesser of (i) the average closing bid quotation of the Common
     Stock as reported on the over-the-counter market, or the
     closing sale price if listed on a national securities
     exchange, for the five (5) trading days immediately preceding
     the date of the Conversion Notice referred to in Section 4.3
     below multiplied by eighty percent (80%) or (ii) U.S. $1.6875. 
     Notwithstanding the foregoing, the Conversion Price shall not
     be less than a minimum of $.75 per share ("Minimum Conversion
     Price"), which Minimum Conversion Price shall be eliminated
     from and after September 6, 1998.  If any of the outstanding
     shares of Series 5 Class E Preferred Stock are converted, in
     whole or in part, into Common Stock pursuant to the terms of
     this Part 4, the number of shares of whole Common Stock to be
     issued to the holder as a result of such conversion shall be
     determined by dividing (a) the aggregate Liquidation Value of
     the Series 5 Class E Preferred Stock so surrendered for
     conversion by (b) the Conversion Price in effect at the date
     of the conversion.  At the time of conversion of shares of the
     Series 5 Class E Preferred Stock, the Corporation shall pay in
     cash to the holder thereof an amount equal to all unpaid and
     accrued dividends, if any, accrued thereon to the date of
     conversion, or, at the Corporation's option, in lieu of paying
     cash for the accrued and unpaid dividends, issue that number
     of shares of whole Common Stock which is equal to the quotient
     of the amount of such unpaid and accrued dividends to the date
     of conversion on the shares of Series 5 Class E Preferred
     Stock so converted divided by the Stock Dividend Price, as
     defined in Section 3.1 hereof, in effect at the date of
     conversion.

4.3  Mechanics of Conversion.  Any holder of the Series 5 Class E
     Preferred Stock who wishes to exercise its Conversion Rights
     pursuant to Section 4.1 of this Part 4 must surrender the
     certificate therefor at the principal executive office of the
     Corporation, and give written notice, which may be via

                             -5-
<PAGE>
     facsimile transmission, to the Corporation at such office that
     it elects to convert the same (the "Conversion Notice").  No
     Conversion Notice with respect to any shares of Series 5 Class
     E Preferred Stock can be given prior to the time such shares
     of Series 5 Class E Preferred Stock are eligible for
     conversion in accordance with the provision of Section 4.1
     above, except as provided in Section 4.4.  Any such premature
     Conversion Notice shall automatically be null and void.  The
     Corporation shall, within seven (7) business days after
     receipt of an appropriate and timely Conversion Notice (and
     certificate, if necessary), issue to such holder of Series 5
     Class E Preferred Stock or its agent a certificate for the
     number of shares of Common Stock to which he shall be
     entitled; it being expressly agreed that until and unless the
     holder delivers written notice to the Corporation to the
     contrary, all shares of Common Stock issuable upon conversion
     of the Series 5 Class E Preferred Stock hereunder are to be
     delivered by the Corporation to a party designated in writing
     by the holder in the Conversion Notice for the account of the
     holder and such shall be deemed valid delivery to the holder
     of such shares of Common Stock.  Such conversion shall be
     deemed to have been made only after both the certificate for
     the shares of Series 5 Class E Preferred Stock to be converted
     have been surrendered and the Conversion Notice is received by
     the Corporation (the "Conversion Documents"), and the person
     or entity whose name is noted on the certificate evidencing
     such shares of Common Stock issuable upon such conversion
     shall be treated for all purposes as the record holder of such
     shares of Common Stock at and after such time.  In the event
     that the Conversion Notice is sent via facsimile transmission,
     the Corporation shall be deemed to have received such
     Conversion Notice on the first business day on which such
     facsimile Conversion Notice is actually received.  

4.4  Merger or Consolidation.  In case of either (a) any merger or
     consolidation to which the Corporation is a party
     (collectively, the "Merger"), other than a Merger in which the
     Corporation is the surviving or continuing corporation, or (b)
     any sale or conveyance to another corporation of all, or
     substantially all, of the assets of the Corporation
     (collectively, the "Sale"), and such Merger or Sale becomes
     effective (x) while any shares of Series 5 Class E Preferred
     Stock are outstanding and prior to the date that the
     Corporation's Registration Statement covering up to 200,000
     shares of Common Stock issuable upon the conversion of the
     Series 5 Class E Preferred Stock is declared effective by the
     U. S. Securities and Exchange Commission or (y) prior to the
     end of the restriction periods in Section 4.1, then, in such
     event, the Corporation or such successor corporation, as the
     case may be, shall make appropriate provision so that the
     holder of each share of Series 5 Class E Preferred Stock then
     outstanding shall have the right to convert such share of
     Series 5 Class E Preferred Stock into the kind and amount of
     shares of stock or other securities and property receivable
     upon such Merger or Sale by a holder of the number of shares
     of Common Stock into which such shares of Series 5 Class E
     Preferred Stock could have been converted into immediately
     prior to such Merger or Sale, subject to adjustments which
     shall be as nearly equivalent as may be practicable to the
     adjustments provided for in this Part 4.


                              -6-
<PAGE>
4.4  Adjustments to Conversion Price for Stock Dividends and for
     Combinations or Subdivisions of Common Stock.  If the
     Corporation at any time or from time to time while shares of
     Series 5 Class E Preferred Stock are issued and outstanding
     shall declare or pay, without consideration, any dividend on
     the Common Stock payable in Common Stock, or shall effect a
     subdivision of the outstanding shares of Common Stock into a
     greater number of shares of Common Stock (by stock split,
     reclassification or otherwise than by payment of a dividend in
     Common Stock or in any right to acquire Common Stock), or if
     the outstanding shares of Common Stock shall be combined or
     consolidated, by reclassification or otherwise, into a lesser
     number of shares of Common Stock, then the Conversion Price in
     effect immediately before such event shall, concurrently with
     the effectiveness of such event, be proportionately decreased
     or increased, as appropriate.

4.5. Adjustments for Reclassification and Reorganization.  If the
     Common Stock issuable upon conversion of the Series 5 Class E
     Preferred Stock shall be changed into the same or a different
     number of shares of any other class or classes of stock,
     whether by capital reorganization, reclassification or
     otherwise (other than a subdivision or combination of shares
     provided for in Section 4.4 hereof), the Conversion Price then
     in effect shall, concurrently with the effectiveness of such
     reorganization or reclassification, be proportionately
     adjusted so that the Series 5 Class E Preferred Stock shall be
     convertible into, in lieu of the number of shares of Common
     Stock which the holders of Series 5 Class E Preferred Stock
     would otherwise have been entitled to receive, a number of
     shares of such other class or classes of stock equivalent to
     the number of shares of Common Stock that would have been
     subject to receipt by the holders upon conversion of the
     Series 5 Class E Preferred Stock immediately before that
     change.

4.6  Common Stock Duly Issued.  All Common Stock which may be
     issued upon conversion of Series 5 Class E Preferred Stock
     will, upon issuance, be duly issued, fully paid and
     nonassessable and free from all taxes, liens, and charges with
     respect to the issue thereof.

4.7  Notice of Adjustments.  Upon the occurrence of each adjustment
     or readjustment of any Conversion Price pursuant to this Part
     4, the Corporation, at its expense, within a reasonable period
     of time, shall compute such adjustment or readjustment in
     accordance with the terms hereof and prepare and furnish to
     each holder of Series 5 Class E Preferred Stock a notice
     setting forth such adjustment or readjustment and showing in
     detail the facts upon which such adjustment is based.

4.8  Issue Taxes.  The Corporation shall pay any and all issue and
     other taxes that may be payable in respect of any issue or
     delivery of shares of Common Stock on conversion of the Series
     5 Class E Preferred Stock pursuant thereto; provided, however,
     that the Corporation shall not be obligated to pay any
     transfer taxes resulting from any transfer requested by any
     holder of Series 5 Class E Preferred Stock in connection with
     such conversion.


                             -7-
<PAGE>
4.9  Reservation of Stock Issuable Upon Conversion.  The
     Corporation shall at all times reserve and keep available out
     of its authorized but unissued shares of Common Stock, solely
     for the purpose of effecting the conversion of the shares of
     the Series 5 Class E Preferred Stock, such number of its
     shares of Common Stock as shall, from time to time, be
     sufficient to effect the conversion of all outstanding shares
     of the Series 5 Class E Preferred stock, and, if at any time,
     the number of authorized but unissued shares of Common Stock
     shall not be sufficient to effect the conversion of all then
     outstanding shares of the Series 5 Class E Preferred Stock,
     the Corporation will take such corporate action as may be
     necessary to increase its authorized but unissued shares of
     Common Stock to such number of shares as shall be sufficient
     for such purposes, including, without limitation, engaging in
     reasonable efforts to obtain the requisite stockholder
     approval of any necessary amendment to its Certificate of
     Incorporation.

4.10 Fractional Shares.  No fractional shares shall be issued upon
     the conversion of any share or shares of Series 5 Class E
     Preferred Stock.  All shares of Common Stock (including
     fractions thereof) issuable upon conversion of more than one
     share of Series 5 Class E Preferred Stock by a holder thereof
     shall be aggregated for purposes of determining whether the
     conversion would result in the issuance of any fractional
     share.  If, after the aforementioned aggregation, the
     conversion would result in the issuance of a fractional share
     of Common Stock, such fractional share shall be rounded up to
     the nearest whole share.

4.11 Notices.  Any notices required by the provisions of this Part
     4 to be given to the holders of shares of Series 5 Class E
     Preferred Stock shall be deemed given if deposited in the
     United States mail, postage prepaid, and addressed to each
     holder of record at his address appearing on the books of the
     Corporation.

4.12 Business Day.  As used herein, the term "business day" shall
     mean any day other than a Saturday, Sunday or a day when the
     federal and state banks located in the State of New York are
     required or is permitted to close.

Part 5 - Redemption.

5.1  Redemption at Corporation's Option.  Except as otherwise
     provided in this Section 5.1, at any time, and from time to
     time, after the expiration of one (1) year from the date of
     the first issuance of the Series 5 Class E Preferred Stock,
     the Corporation may, at its sole option, but shall not be
     obligated to, redeem, in whole or in part, at any time, and
     from time to time, the then outstanding Series 5 Class E
     Preferred Stock at the following cash redemption prices per
     share (the "Redemption Price") if redeemed during the
     following periods: (a) within four (4) years from the date of
     the first issuance of Series 5 Class E Preferred Stock -
     $1,300 per share, if at any time during such four (4) year
     period the average of the closing bid price of the Common
     Stock for ten (10) consecutive trading days shall be in excess

                            -8-
<PAGE>
     of Four U.S. Dollars ($4.00) per share, and (b) after four (4)
     years from the date of the first issuance of Series 5 Class E
     Preferred Stock - $1,000 per share.

5.3  Mechanics of Redemption.  Thirty (30) days prior to any date
     stipulated by the Corporation for the redemption of Series 5
     Class E Preferred Stock (the "Redemption Date"), written
     notice (the "Redemption Notice") shall be mailed to each
     holder of record on such notice date of the Series 5 Class E
     Preferred Stock.  The Redemption Notice shall state: (i) the
     Redemption Date of such shares, (ii) the number of Series 5
     Class E Preferred Stock to be redeemed from the holder to whom
     the Redemption Notice is addressed, (iii) instructions for
     surrender to the Corporation, in the manner and at the place
     designated, of a share certificate or share certificates
     representing the number of Series 5 Class E Preferred Stock to
     be redeemed from such holder, and (iv) instructions as to how
     to specify to the Corporation the number of Series 5 Class E
     Preferred Stock to be redeemed as provided in this Part 5.

5.4  Rights of Conversion Upon Redemption.  If the redemption
     occurs after the first one hundred eighty (180) days after the
     first issuance of Series 5 Class E Preferred Stock, then, upon
     receipt of the Redemption Notice, any holder of Series 5 Class
     E Preferred Stock shall have the option, at its sole election,
     to specify what portion of its Series 5 Class E Preferred
     Stock called for redemption in the Redemption Notice shall be
     redeemed as provided in this Part 5 or converted into Common
     Stock in the manner provided in Part 4 hereof.

5.5  Surrender of Certificates.  On or before the Redemption Date
     in respect of any Series 5 Class E Preferred Stock, each
     holder of such shares shall surrender the required certificate
     or certificates representing such shares to the Corporation in
     the manner and at the place designated in the Redemption
     Notice, and upon the Redemption Date, the Redemption Price for
     such shares shall be made payable, in the manner provided in
     Section 5.6 hereof, to the order of the person whose name
     appears on such certificate or certificates as the owner
     thereof.  If a share certificate is surrendered and all the
     shares evidenced thereby are not being redeemed (as described
     below), the Corporation shall cause the Series 5 Class E
     Preferred Stock which are not being redeemed to be registered
     in the names of the persons or entity whose names appear as
     the owners on the respective surrendered share certificates
     and deliver such certificate to such person.

5.6  Payment.  On the Redemption Date in respect of any Series 5

    WHEREAS, Centofanti is the Chairman of the Board and President
of PESI; and

    WHEREAS, Centofanti and PESI have negotiated this Agreement in
which Centofanti would acquire 24,381 shares of PESI Common Stock
for $40,000, which is seventy-five percent (75%) of the closing bid
price of each share of PESI Common Stock as quoted on the NASDAQ on
the date hereof; and

    WHEREAS, the closing bid price of the PESI Common Stock was
$2.1875, as reported on the NASDAQ as of June 30, 1997; and

shares of Common Stock, upon the terms and conditions set forth
herein.

    NOW, THEREFORE, in consideration of the mutual promises and the
respective covenants and agreements contained herein, the parties
hereto agree as follows:

1.  Purchase and Sale.

    1.1  Purchase of Shares.  Subject to the terms and
         conditions of this Agreement, Centofanti hereby
         purchases Twenty-four Thousand Three Hundred Eight-one

         share purchase price of the Shares shall be $1.6406,

<PAGE>
2.  Representations and Warranties of Centofanti.  Centofanti
    represents and warrants as follows:

    2.1  Purchase for Investment.  Centofanti is acquiring, or
         will acquire, the Shares to hold for investment, with
         no present intention of dividing Centofanti'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 of 1933, as amended (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 the Shares 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 or
         the rules and regulations promulgated thereunder by the
         Securities and Exchange Commission (the "SEC").

    2.2  No Registration.  Centofanti acknowledges that the
         Shares are not being registered under any state
         securities laws, and are not being registered under the
         Securities Act on the ground that this transaction is
         exempt from registration under Section 3(b) and/or 4(2)
         of the Securities Act, and that reliance by PESI on
         such exemptions is predicated in part on Centofanti's
         representations set forth herein.

    2.3  Restricted Transfer.  Centofanti agrees that PESI may
         refuse to permit the sale, transfer or disposition of
         any of the Shares received by Centofanti unless there
         is in effect a registration statement under the Secur-
         ities Act and any applicable state securities law
         covering such transfer or Centofanti furnishes an
         opinion of counsel or other evidence, reasonably
         satisfactory to counsel for PESI, to the effect that
         such registration is not required.

    2.4  Legend.  Centofanti understands and agrees that stop
         transfer instructions will be given to PESI's transfer
         agent and that there will be placed on the certificate
         or certificates for any of the Shares received by
         Centofanti, any substitutions therefor and any certif-
         icates for any additional shares which might be dis-
         tributed with respect to such Shares, a legend stating
         in substance:

              "The shares of stock evidenced by this
           certificate have been acquired for investment and
           have not been registered under the Securities Act
           of 1933, as amended (the Securities Act").  These
           shares may not be sold or transferred except
           pursuant to an effective registration statement
           under the Securities Act and any applicable state
           securities laws unless there is furnished to the
           issuer an opinion of counsel or other evidence,
           reasonably satisfactory to the issuer's counsel,
           to the effect that such registration is not
           required."


                             -2-
<PAGE>
    2.5  Indefinite Holding Period.  Centofanti understands that
         under the Securities Act, the Shares received by
         Centofanti must be held indefinitely unless they are
         subsequently registered under the Securities Act or
         unless an exemption from such registration is available
         with respect to any proposed transfer or disposition of
         such shares.

    2.6  Rule 144 Compliance.  Centofanti understands that PESI
         is required to file periodic reports with the SEC and
         that certain sales of the Shares received by Centofanti
         may be exempt from registration under the Securities
         Act by virtue of Rule 144 promulgated by the SEC under
         the Securities Act, provided that such sales are made
         in accordance with all of the terms and conditions of
         that Rule including compliance with the required two-
         year holding period.  Centofanti further understands
         that if Rule 144 is not available for sales of the
         Shares received by Centofanti, such Shares may not be
         sold without registration under the Securities Act or
         compliance with some other exemption from such
         registration, and that PESI has no obligation to
         register the Shares received by Centofanti or take any
         other action necessary in order to make compliance with
         an exemption from registration available.

    2.7  Sophisticated Investor.  Centofanti, as President and
         Chairman of the Board of PESI, possesses extensive
         knowledge as to the business and operation of PESI and
         has such knowledge and experience in financial and
         business matters that he is capable of evaluating the
         merits and risks of the acquisition of the Shares.

3.  Representations and Warranties of  PESI.  PESI represents and
    warrants as follows:

    3.1  Organization and Standing.  PESI is a corporation duly
         organized, validly existing and in good standing under
         the laws of the State of Delaware.

         power and corporate authority to enter into this
