THIS WARRANT AGREEMENT AND THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE OF THIS WARRANT AGREEMENT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD OR TRANSFERRED
EXCEPT (A) UNDER COVER OF A REGISTRATION STATEMENT UNDER SUCH ACT WHICH IS EFFECTIVE AND CURRENT WITH RESPECT TO THIS WARRANT AGREEMENT OR SUCH SHARES OF COMMON STOCK, AS THE CASE MAY BE, OR (B) PURSUANT TO THE WRITTEN OPINION OF COUNSEL REASONABLY

_______________ Warrants

WARRANT AGREEMENT 

      This WARRANT AGREEMENT (the "Agreement") is made effective the ___ day of _________, 2001 (the "Issue Date"), between PERMA-FIX ENVIRONMENTAL SERVICES, INC. a Delaware corporation (the
"Company"), and _______________________, a[n] _______________ ("Registered Holder").

WITNESSETH:

     WHEREAS, in connection with a private placement (the "Offering") by the Company of a minimum of 1.5 million and a maximum of 4.4 million units ("Units"), each Unit consisting of one share of the Company's
common stock, par value $.001 per share ("Common Stock"), and one warrant to purchase one share of Common Stock (a "Warrant") as described in the Confidential Private Placement Memorandum, dated April 6, 2001, as amended by Amendment No. 1 to the
Confidential Private Placement Memorandum dated June __, 2001, the Registered Holder has purchased from the Company the same number of Units as the number of Warrants set forth above pursuant to the terms and conditions of a Subscription Agreement between
the Registered Holder and the Company (the "Subscription Agreement"); and

     WHEREAS, in reliance upon the representations made by the Registered Holder in (a) this Agreement, (b) the Subscription Agreement, dated the same date as this Agreement, between the Company and the Registered Holder (the
"Subscription Agreement"), and (c) the Investor Questionnaire completed by the Registered Holder and delivered to the Company in connection with the Offering and the purchase of Units by the Registered Holder (the "Questionnaire"), the offer and purchase
of securities under this Agreement will be exempt from registration under applicable federal securities laws because this is a private placement and intended to be a nonpublic offering pursuant to Sections 4(2) and/or 3(b) of the Securities Act of 1933,
as amended (the "Act"), and/or Regulation D promulgated under the Act;

     WHEREAS, the Common Stock is listed for trading on the Boston Stock Exchange and the National Association of Securities Dealers Automated Quotation SmallCap market ("NASDAQ"), and the Company is subject to the reporting
requirements of Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and has been subject to such filing requirements for the past 90 days; and

 

B1

 

      WHEREAS, this Agreement sets forth the terms and conditions of the Warrants included in the Units purchased by the Registered Holder under the Offering.

      NOW THEREFORE, in consideration of the mutual promises herein contained and intending to be legally bound, the parties hereby agree as follows:

1.  Warrants.  The Company hereby grants to Registered Holder Warrants for the right to purchase up to an aggregate of ____________________ shares of Common Stock (the "Warrant Shares") at an initial exercise price (subject to adjustment
as provided in paragraph 14 below) of $1.75 per share of Common Stock (the "Exercise Price"), subject to the terms and conditions of this Agreement.  Except as set forth herein, the Warrant Shares issuable upon exercise of the Warrants are in all respects
identical to the shares of Common Stock that have been issued to the public. The Registered Holder may exercise all or any number of Warrants resulting in the purchase of a whole number of Warrant Shares.

2.  Exercise Period.  The Warrants may be exercised at any time commencing after the date upon which notice is received by the Registered Holder that the shareholders of the Company have approved the exercise of the Warrants at the
Exercise Price and ending at 5:00 p.m., Eastern Standard Time, on the fifth anniversary date of the Issue Date, subject to paragraph 9 of this Agreement

3.  Warrant Certificates.  The warrant certificates (the "Warrant Certificates") delivered and to be delivered pursuant to this Agreement will be in the form set forth in Exhibit A, attached hereto and made a part hereof, with such
appropriate insertions, omissions, substitutions, and other variations as required or permitted by this Agreement.  Warrant Certificates will be manually countersigned by the Company and will not be valid for any purpose unless so countersigned.

4.  Issuance of New Certificates.  Notwithstanding any of the provisions of this Agreement or any Warrant Certificate to the contrary, the Company may, at its option, issue one or more new Warrant Certificates in such form as may be
approved by its Board of Directors to reflect any adjustment or change in the Exercise Price or the number or kind of shares purchasable under the each Warrant Certificate made in accordance with the provisions of this Agreement.

5.  Exercise of Warrant.  Subject to the terms of this Agreement, the Warrants initially are exercisable at an aggregate initial exercise price per share of Common Stock set forth in paragraph 1 hereof payable by certified or cashier's
check in United States dollars, subject to adjustment as provided in paragraph 14 of this Agreement.  Upon surrender of a Warrant Certificate with the annexed Form of Election to Purchase duly executed, together with payment in full of the exercise price
for the shares of Common Stock purchased pursuant to the terms of this Agreement, at the Company's principal offices (presently located at 1940 Northwest 67th Place, Gainesville, Florida  32653), the Registered Holder will be entitled to receive a certificate or certificates for the shares of Common Stock so purchased.  The purchase rights represented by each Warrant Certificate are exercisable at
the option of the Registered Holder, in whole or in part (but not as to fractional shares of the Common Stock underlying the Warrants).  Warrants may be exercised to purchase all or part of the Warrant Shares.  If less than all the Warrant Shares are
purchased under any Warrant Certificate, the Company will cancel the Warrant Certificate upon the surrender thereof and will execute and deliver a new Warrant Certificate of like tenor for the balance of the Warrant Shares purchasable under the original
Warrant Certificate.

6.  Issuance of Certificates.  Upon the exercise of all or any portion of the Warrants, the issuance of certificates for the Warrant Shares underlying the Warrants so exercised, will be made promptly (and in any event within 10 business
days thereafter) without charge to the Registered Holder exercising such Warrants, including,
 

B2

 

without limitation, any tax which may be payable in respect of the issuance thereof, and such certificates will be issued in the name of the Registered Holder.  The Warrants and the certificates representing the Warrant Shares will be executed on
behalf of the Company by the manual or facsimile signature of the then Chairman or Vice Chairman of the Board of Directors or President or Vice President of the Company.

7.  Restriction on Transfer of Warrants or Warrant Shares.  The Registered Holder, by Registered Holder's acceptance of this Agreement, covenants and agrees that the Warrants are being acquired as an investment and not with a view to the
distribution thereof.  The Registered Holder, by acceptance of this Agreement, agrees that (a) no public distribution of Warrants or Warrant Shares will be made in violation of the provisions of the Act and the Rules and Regulations promulgated thereunder
and (b) during such period as delivery of a prospectus with respect to Warrants or Warrant Shares may be required by the Act, no public distribution of Warrants or Warrant Shares will be made in a manner or on terms different from those set forth in, or
without delivery of, a prospectus then meeting the requirements of Section 10 of the Act and in compliance with all applicable state securities laws.  The Registered Holder and each permitted transferee of the Registered Holder further agrees that if any
transfer or other distribution of any of the Warrants or Warrant Shares is proposed to be made by them other than by delivery of a prospectus meeting the requirements of Section 10 of the Act, such action will be taken only after receipt by the Company of
an opinion of its counsel, or an opinion of counsel reasonably satisfactory to the Company, to the effect that the proposed transfer or other distribution will not be in violation of the Act or applicable state law.  As a condition to the transfer of the
Warrants, any transferee of the Warrants must deliver to the Company a written agreement to accept and be bound by all of the terms and conditions contained in this Agreement.  Any Warrant Shares issued upon exercise of the Warrants will bear a legend to
the following effect:

The securities represented by this certificate have not been registered under the Securities 

 Act of 1933, as amended (the "Act"), or qualified under applicable state securities laws, 

 and are restricted securities within the meaning of the Act.  Such securities may not be sold

or transferred, except pursuant to a registration statement under such Act and qualification

under applicable state securities laws which are effective and current with respect to such

securities or pursuant to an opinion of counsel reasonably satisfactory to the issuer of such

securities that registration and qualification are not required under applicable federal or

state securities laws or an exemption is available therefrom.  

8.  Warrant Holder Not Shareholder.  Neither this Agreement nor the Warrant Certificate will be deemed to confer upon the Registered Holder any right to vote the Warrant Shares or to consent to or receive notice as a shareholder of
the Company as such, because of this Agreement or the Warrant Certificate, in respect of any matters whatsoever, or any other rights or liabilities as a shareholder.

9.  Taxes.  The Company will pay all taxes attributable to the initial issuance of Warrant Shares upon exercise of Warrants. The Company will not, however, be required to pay any tax which may be payable in respect to any transfer
involved in any issue of Warrant Certificates or in the issue of any certificates of Warrant Shares in the name other than that of the Registered Holder upon the exercise of any Warrant, as the case may be.

10.  Mutilated or Missing Certificates.  If any Warrant Certificate is mutilated, lost, stolen or destroyed, the Company may, on such terms as to indemnity or otherwise as they it in its discretion impose (which will, in the case of a
mutilated Warrant Certificate, include the surrender thereof), and upon receipt of evidence satisfactory to the Company of such mutilation, loss, theft or destruction, issue a substitute Warrant Certificate, respectively, of like denomination or tenor as
the Warrant Certificate so mutilated, lost, stolen or destroyed.

 

B3

 

Applicants for substitute Warrant Certificates will comply with such other reasonable regulations and pay any reasonable charges as the Company may prescribe.

11.  Subsequent Issue of Certificates.  Subsequent to their original issuance, no Warrant Certificates will be reissued except (a) such Certificates issued upon transfer thereof in accordance with paragraph 7 hereof, (b) such
Certificates issued upon any combination, split-up or exchange of Warrant Certificates pursuant to paragraph 14 hereof, (c) such Certificates issued in replacement of mutilated, destroyed, lost or stolen Warrant Certificates pursuant to paragraph 10
hereof, (d) Warrant Certificates issued upon the partial exercise of Warrant Certificates pursuant to paragraph 5 hereof, and (e) Warrant Certificates issued to reflect any adjustment or change in the Exercise Price or the number or kind of shares
purchasable thereunder pursuant to paragraph 14
hereof.

12.  Reservation of Shares.  For the purpose of enabling the Company to satisfy all obligations to issue Warrant Shares upon exercise of Warrants, the Company will at all times reserve and keep available free from preemptive rights, out
of the aggregate of its authorized but unissued shares, the full number of Shares which may be issued upon the exercise of the Warrants. The Company covenants all shares which will be so issuable upon exercise of the Warrants, will upon issue be fully
paid and nonassessable by the Company and free from all taxes, liens, charges and security interests with respect to the issue thereof.

13.  Registration.  The Warrant Shares issuable upon exercise of the Warrants are subject to the registration rights set forth in the Subscription Agreement.

14.  Adjustments of Number and Kind of Shares Purchasable and Exercise Price.  The number and kind of securities or other property purchasable upon exercise of a Warrant will be subject to adjustment from time to time upon the
occurrence, after the date hereof, of any of the following events.

      14.1  Distributions; Dividends; Subdivisions; Combinations.   If the Company (a) pays a dividend in,

               or makes a distribution of, shares of capital stock on its outstanding Common Stock; (b) 

               subdivide its outstanding shares of Common Stock into a greater number of shares; or (c) 

               combines its outstanding shares of Common Stock into a smaller number of shares, then 

               the total number of shares of Common Stock purchasable upon the exercise of each 

               Warrant outstanding immediately prior to such event will be adjusted so that the Registered 

               Holder of any Warrant Certificate will be entitled, upon proper exercise of the Warrants, to 

               receive at the same aggregate Exercise Price the number of shares of capital stock (of one or 

               more classes) which the Registered Holder would have owned or have been entitled to 

               receive immediately following the happening of any of the events described above had such 

               Warrant been exercised in full immediately prior to the record date with respect to such event. 

               Any adjustment made pursuant to this paragraph 14.1 will, in the case of a stock dividend or

               distribution, become effective as of the applicable record date and, in the case of a subdivision 

               or combination, be made as of the effective date of the event. If, as a result of an adjustment 

               made pursuant to this paragraph, the Registered Holder of any Warrant Certificate becomes 

               entitled, upon proper exercise of the Warrants, to receive shares of two or more classes of 

               capital stock of the Company, the Board of Directors of the Company (whose determination 

               will be conclusive and will be evidenced by a Board resolution) will determine the allocation 

               of the adjusted Exercise Price between or among shares of such classes of capital stock.

      14.2  Consolidation; Merger.  If the Company consolidates with, or merges into, another corporation 

              (other than a consolidation or merger which does not result in any reclassification or change of 

              the outstanding Common Stock), or in case of any sale or conveyance to another corporation 

 

B4

 

              of the property of the Company as an entirety or substantially as an entirety, the corporation 

              formed by such consolidation or merger or the corporation which will have acquired such 

              assets, as the case may be, will execute and deliver to the Registered Holder a supplemental 

              warrant agreement providing that the Registered Holder will, with respect to each Warrant 

              then outstanding and held by the Registered Holder, have the right thereafter (until the expiration

              of such Warrant) to receive, upon exercise of such Warrant, solely the kind and amount of 

              shares of stock and other securities and property (or cash) receivable upon such consolidation,

              merger, sale or transfer by a holder of the number of shares of Common Stock of the Company 

              for which such Warrant might have been exercised immediately prior to such consolidation, 

              merger, sale or transfer. Such supplemental warrant agreement will provide for adjustments 

              which will be as nearly equivalent as may be practicable to the adjustments provided in this 

              paragraph. The provision of this paragraph will similarly apply to successive consolidations, 

              mergers, sales or transfers.

     14.3  Reorganization; Reclassification.  If any capital reorganization or a reclassification of the Common

              Stock (except as provided in paragraphs 14.1 and 14.2 above), will be effected, then, as a 

              condition of such reorganization or reclassification, lawful and adequate provision will be made

              whereby the Registered Holder, upon exercise of Warrants, will thereafter have the right to 

              purchase and receive, upon the basis and upon the terms and conditions specified herein and 

              in the Warrants and, in substitution for the Common Stock to which the Registered Holder 

              would have become entitled upon exercise immediately prior to such reorganization or 

              reclassification, the shares (of any class or classes) or other securities or property of the 

              Company (or cash) that the Registered Holder would have been entitled to receive at the same

              aggregate Exercise Price upon such reorganization or reclassification if the Warrants had been

              exercised immediately prior to the record date with respect to such event; and in any such case,

              appropriate provision (as determined by the Board of Directors of the Company, whose

              determination will be conclusive and will be evidenced by a certified Board resolution filed with 

              the Warrant Agent) will be made for the application of this paragraph with respect to the rights 

              and interests thereafter of the Registered Holders (including but not limited to the allocation of 

              the Exercise Price between or among shares of classes of capital stock), to the end that this 

              paragraph (including the adjustments of the number of shares of Common Stock or other 

              securities purchasable and the Exercise Price of the Warrants) will thereafter be reflected, as 

              nearly as reasonably practicable, in all subsequent exercises of the Warrants for any shares 

              or securities or other property (or cash) thereafter deliverable upon the exercise of the 

              Warrants.

      14.4  Certification of Adjustment.  Whenever the number of shares of Common Stock or other 

               securities purchasable upon exercise of a Warrant is adjusted as provided in this paragraph, 

               the Company will provide the Registered Holder a certificate signed by the Chairman of the 

               Board or the President or a Vice President of the Company setting forth the number and 

               kind of securities or other property purchasable upon exercise of a Warrant, as so adjusted, 

               stating that such adjustments in the number or kind of shares or other securities or property 

               conform to the requirements of this paragraph, and setting forth a brief statement of the facts

               accounting for such adjustments.

     14.5  Change of Certificate.  Irrespective of any adjustments in the number or kind of shares issuable 

              upon exercise of Warrants, Warrant Certificates theretofore or thereafter issued may continue 

 

B5

 

              to express the same price and number and kind of shares as are stated in the similar Warrant

              Certificates initially issuable pursuant to this Agreement.

      14.6  Certification.  The Company may retain a firm of independent public accountants of recognized

               standing, which may be the firm regularly retained by the Company, selected by the Board of

               Directors of the Company or the Executive Committee of the Board, to make any computation

               required under this paragraph, and a certificate signed by such firm will, in the absence of fraud

               or gross negligence, be conclusive evidence of the correctness of any computation made under 

               this paragraph.

     14.7   Common Stock.   For the purpose of this paragraph, the term "Common Stock" will mean (a) 

               the Common Stock or (b) any other class of stock resulting from successive changes or

              
reclassifications of such Common Stock consisting solely of changes in par value, or from par 

               value to no par value, or from no par value to par value. If, at any time as a result of an 

               adjustment made pursuant to this paragraph, the Registered Holder of any Warrant thereafter

              
surrendered for exercise will become entitled to receive any shares of capital stock of the 

               Company other than shares of Common Stock, thereafter the number of such other shares so

              
receivable upon exercise of any Warrant will be subject to adjustment from time to time in a 

               manner and on terms as nearly equivalent as practicable to the provisions with respect to the

              
Common Stock contained in this paragraph, and all other provisions of this Agreement, with 

               respect to the Common Stock, will apply on like terms to any such other shares.

     14.8  Reduction of Exercise Price.  The Company may, from time to time and to the extent 

              permitted by law, reduce the exercise price of the Warrants by any amount for a period of not 

              less than 20 days. If the Company so reduces the exercise price of the Warrants, it will give 

              not less than 15 days notice of such decrease, which notice may be in the form of a press 

              release, andwill take such other steps as may be required under applicable law in connection 

              with any offers or sales of securities at the reduced price.

     14.9  No Adjustment of Exercise Price in Certain Cases.  No adjustment of the exercise price will 

              be made if the amount of the adjustment is less than two cents per Warrant Share, provided,

              however, that in such case any adjustment that would otherwise be required then to be made 

              will be carried forward and will be made at the time of, and together with, the next subsequent

              adjustment which, together with any adjustment so carried forward, will amount to at least 

              two cents per Warrant Share.

15.  Reduction of Exercise Price Below Par Value.  Before taking any action that would cause an adjustment pursuant to paragraph 14 of this Agreement reducing the portion of the exercise price required to purchase one share of
capital stock below the then par value (if any) of a share of such capital stock, the Company will use its best efforts to take any corporate action which, in the opinion of its counsel, may be necessary in order that the Company may validly and legally
issue fully paid and non-assessable shares of such capital stock.

16.  No Fractional Warrants or Warrant Shares.  The Company will not be required to issue fractions of Warrants upon the reissue of Warrants or any adjustments as described in paragraph 15, or otherwise; but the Company in lieu of
issuing any such fractional interest, will adjust the fractional interest by payment to the Registered Holder an amount, in cash, equal to the current market value of any such fraction or interest. If the total Warrants surrendered by exercise would
result in the issuance of a fractional share of Common Stock, the

 

B6

 

Company will not be required to issue a fractional share, but rather the resulting fractional interest will be adjusted by payment in an amount, in cash, equal to the current market value of such fractional interest.

17.  Agreement of Registered Holder.  Every Registered Holder by accepting the same consents and agrees with the Company, and with every other holder of a Warrant Certificate, respectively, that (a) the Warrant Certificates are transferable
on the registry books of the Company only upon the terms and conditions set forth in this Agreement; and (b) the Company may deem and treat the person in whose name the Warrant Certificate is registered as the absolute owner of the Warrant
(notwithstanding any notation of ownership or other writing thereon made by anyone other than the Company) for all purposes whatsoever, and the Company will not be affected by any notice to the contrary.

18.  Notices.  Any notice or demand authorized by this Agreement to be given or made by the  Registered Holder to or on the Company will be sufficiently given or made if sent by mail, first class, certified or registered, postage
prepaid, addressed as follows:

to the terms of this Warrant and such suspension continues past the Expiration Date, this Agreement will terminate at the close of business on the business day immediately following the expiration of such suspension.

22.  Governing Law.  This Agreement and each Warrant Certificate issued hereunder will be deemed to be a contract made under the laws of the State of Delaware and for all purposes will be construed in accordance

 

B7

 

with the laws of said State without giving effect to its conflicts of law provisions.  The Registered Holder hereby irrevocably consents to the venue and jurisdiction of the federal courts located in Wilmington, Delaware.

23.  Benefits of this Agreement.  Nothing in this Agreement will be construed to give any person or corporation other than the Company and the Registered Holder any legal or equitable right, remedy or claim under this Agreement; but this
