	 	7.5	No
    Default. To PESI’s knowledge, the making and performance by PESI of this Loan Agreement or the documents to be executed
    in connection herewith will not violate any provision or constitute a default under any indenture, agreement or instrument

severally, to PESI as follows:


 


	 	8.1	Investment
    Intent. The Lender is acquiring the Shares and Warrants for his own account as principal, not as a nominee or agent, for
    investment purposes only, and not with a view to, or for, resale, distribution or fractionalization thereof in whole or in
    part and no other person has a direct or indirect beneficial interest in such Shares and Warrants. The Lender does not have

	 	8.4	Investment
    Representations. The Lender acknowledge and agrees that the Shares and Warrants acquired under this Loan Agreement and
    the Warrant Shares issuable under the Warrants are not being registered under any applicable federal or state securities laws
    on the ground that the issuance thereof is exempt from registration, and are not being registered under the Securities Act
    of 1933, as amended (the “Act”), on the ground that the issuance thereof is exempt from registration under Rule
    506 of Regulation D and/or Section 4(2) of the Act and that reliance by PESI on such exemptions is predicated in part on the
    Lender’s representations and warranties set forth in this Loan Agreement. In furtherance thereof, the Lender represent
    and warrant to and agrees with PESI and its affiliates as follows:



 


	 	(a)	Lender
    realizes that the basis for the exemption may not be present if, notwithstanding such representations, Lender has in mind
    merely acquiring the Shares, Warrants or Warrant Shares for a fixed or determinable period in the future, or for a market
    rise, or for sale if the market does not rise. The Lender does not have any such intention;
	 	 	 
	 	(b)	Lender
    has the financial ability to bear the economic risk of his investment, has adequate means for providing for current needs
    and personal contingencies and has no need for liquidity with respect to an investment in PESI;
	 	 	 
	 	(c)	Lender
    has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of
    the prospective investment in the Shares, Warrants and the Warrant Shares; and
	 	 	 
	 	(d)	Lender
    is an accredited investor as defined in Rule 501 of the Act, for the following reasons, which are not intended to be exclusive:
    Lender has a net worth in excess of $1,000,000 (exclusive of the value of such Lender’s primary residence) and net income
    in excess of $200,000 in each of the two most recent years and has reasonable expectation of reaching the same income level
    in the current year.


 


	 	8.5
    	Due
    Diligence. The Lender:



 


	 	(a)	has
    been furnished for a reasonable period of time prior to the date hereof with the SEC Filings and all documents which have
    been delivered to, or made available upon request by, the Lender (collectively with this Loan Agreement, the “Investment
    Materials”) and Lender has carefully read and evaluated the Investment Materials and understand the risks involved in
    an investment in the Shares and Warrants, including the risks set forth under the section titled “Risk Factors”
    in the Form 10-K and the considerations set forth in the Investment Materials, and have relied solely (except as indicated
    in subsections (b) and (c) below) on the information contained in the Investment Materials (including all exhibits thereto);
	 	 	 
	 	(b)	has
    been provided an opportunity, for a reasonable period of time prior to the date hereof, to obtain additional information concerning
    the acquisition of the Shares and Warrants, PESI and all other information to the extent PESI possesses such information or
    can acquire it without unreasonable effort or expense;
	 	 	 
	 	(c)	has
    been given the opportunity, for a reasonable period of time prior to the date hereof, to ask questions of and receive answers
    from, PESI or its representatives concerning the terms and conditions of the acquisition of the Shares and Warrants and other
    matters pertaining to an investment therein, and have been given the opportunity for a reasonable period of time prior to
    the date hereof to obtain such additional information necessary to verify the accuracy of the information contained in the
    Investment Materials or that which was otherwise provided in order to evaluate the merits and risks of a purchase of the Shares
    and Warrants;


 




    	 	5	 



     

    

 


	 	(d)	has
    not been furnished with any oral representation or oral information in connection with the acquisition of the Shares and Warrants
    which is not contained in the Investment Materials; and
	 	 	 
	 	(e)	has
    determined that the Shares and Warrants are a suitable investment for the Lender and that at this time the Lender could bear
    a complete loss of such investment.


 


	 	8.6	Restricted Use of Confidential Information.






 


	 	(a)	The
    Lender acknowledges that certain Investment Materials disclosed to him may contain material information regarding PESI that
    has not been disclosed to the public (“Confidential Information”). Lender agree that such Confidential Information
    will be kept confidential by him and, without limiting the foregoing, will not be disclosed by the Lender to any person except
    (i) with the specific prior written consent of PESI, (ii) to a person that has executed a confidentiality agreement, the terms
    and conditions of which are approved in writing by PESI, or (iii) to the Lender’s representatives that have a fiduciary
    relationship to the Lender and have acknowledged to the Lender that he or she is aware that such information is Confidential
    Information and is subject to the restrictions and limitations of this Section 8.6.
	 	 	 
	 	(b)	The
    Lender agrees that neither he nor any affiliate or representative will trade in PESI’s securities while in possession
    of such Confidential Information of PESI and will not communicate such information to any other person under circumstances
    except as otherwise provided in Subsection 8.6(a) above.
	 	 	 
	 	(c)	The
    term “Confidential Information” does not include information which is or becomes generally available to the public
    other than as a result of a disclosure by the Lender or any of his affiliates or representatives.
	 	 	 
	 	(d)	If
    the Lender or any of his affiliates or representatives are requested or become legally compelled (by oral questions, interrogatories,
    requests for information or documents, subpoena, civil or criminal investigative demand, or similar process) or is required
    by a regulatory body to make any disclosure that is prohibited or otherwise constrained by this Agreement, the undersigned
    will provide PESI with prompt notice of such request so that PESI may seek an appropriate protective order or other appropriate
    remedy and/or waive compliance with this Section 8.6.






 




    	 	6	 



     

    

 





	 	(e)	The
    Lender acknowledge that this Section 8.6 as to the disclosure to him by PESI of any Confidential Information shall constitute
    a confidentiality agreement for the purposes of Regulation FD promulgated by the SEC.








 








	 	8.7	No
    Reliance. The Lender is not relying on PESI or its affiliates with respect to economic considerations involved in an investment
    in the Shares, Warrants and Warrant Shares. The Lender has relied on the advice of, or has consulted with only his lawyer,
    accountant, and advisors in connection with the transactions contemplated by this Loan Agreement. The Lender is capable of
    evaluating the merits and risks of an investment in the Shares and Warrants on the terms and conditions set forth in this
    Loan Agreement.
	 	 	 
	 	8.8	Restrictions
    on Transfer. In addition to the restrictions contained in Section 8.6 hereof, the Lender represent, warrant and agree
    that he will not sell or otherwise transfer the Shares and Warrants without registration under the Act or an exemption therefrom
    and fully understands and agrees to bear the economic risk of any purchase because, among other reasons, the Shares, Warrants
    and the Warrant Shares have not been registered under the Act or under the securities laws of any state and, therefore, cannot
    be resold, pledged, assigned or otherwise disposed of unless, inter alia, they are subsequently registered under the
    Act and under the applicable securities laws of such states or an exemption from such registration is available. In particular,
    the Lender is aware that the Shares and Warrants (as well as the Warrant Shares when issued) are “restricted securities,”
    as such term is defined in Rule 144 promulgated under the Act (“Rule 144”), and they may not be sold pursuant
    to Rule 144 unless all of the conditions of Rule 144 are met. The Lender also understand that PESI is under no obligation
    to register the Shares, the Warrants, or the Warrant Shares on the Lender’s behalf or to assist the Lender in complying
    with any exemption from registration under the Act or applicable state securities laws. The Lender further understands that
    U. S. securities laws, applicable state securities laws, and the provisions of this Loan Agreement further restrict sales
    or transfers of the Shares, Warrants and Warrant Shares.
	 	 	 
	 	8.9	Representations.
    No representations or warranties have been made to the Lender by PESI, or any officer, employee, agent, affiliate or subsidiary
    of PESI, other than the representations of PESI contained herein and in connection with this Loan Agreement the Lender have
    not relied upon any representations other than those expressly contained herein.
	 	 	 
	 	8.10	Financial
    Information. Any information which the Lender has heretofore furnished to PESI with respect to his financial position
    and business experience is correct and complete as of the date of this Loan Agreement and if there should be any material
    change in such information the Lender shall immediately furnish such revised or corrected information to PESI.




 







    	 	7	 



     

    

 





	 	8.11	Restrictive
    Legends. The Lender understands and agrees that the certificates for the Shares and Warrants (and the Warrant Shares when
    issued) will bear, substantially, the following legend until (a) such securities will have been registered under the Act and
    effectively been disposed of in accordance with an effective registration statement; or (b) in the opinion of counsel for
    PESI such securities may be sold without registration under the Act, as well as any applicable “Blue Sky” or state
    securities laws:







 


THE
SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”),
AND ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AS SET FORTH IN THIS CERTIFICATE AND THE LOAN AGREEMENT, DATED April 1, 2019,
BETWEEN PERMA-FIX ENVIRONMENTAL SERVICES, INC., AND ROBERT FERGUSON. THE SECURITIES REPRESENTED HEREBY ALSO MAY NOT BE OFFERED,
SOLD, PLEDGED, HYPOTHECATED, ASSIGNED, TRANSFERRED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
UNDER THE ACT WHICH IS CURRENT WITH RESPECT TO THESE SECURITIES OR PURSUANT TO A SPECIFIC EXEMPTION FROM REGISTRATION UNDER THE
ACT BUT ONLY UPON A HOLDER HEREOF FIRST HAVING OBTAINED THE WRITTEN OPINION OF COUNSEL, REASONABLY ACCEPTABLE TO COUNSEL FOR PESI,
TO THE EFFECT THAT THE PROPOSED DISPOSITION MAY BE EFFECTUATED WITHOUT REGISTRATION UNDER THE ACT.”


 





	 	8.12	Speculative
    Investment. The Lender understand that an investment in the Shares, the Warrants and the Warrant Shares is a speculative
    investment that involves a high degree of risk and the potential loss of the entire investment.
	 	 	 
	 	8.13	Overall
    Commitments. The Lender’s overall commitment to investments that are not readily marketable is not disproportionate
    to the Lender’s net worth, and an investment in the Shares, the Warrants and the Warrant Shares will not cause such
    overall commitment to become excessive.
	 	 	 
	 	8.14	Survival.
    The representations, warranties and agreements of the Lender set forth in this Loan Agreement will survive the Closing.




 










    	 	8	 



     

    

 


9.
Indemnity. The Lender agree, jointly and severally, to indemnify and hold harmless PESI, its officers and directors, employees
and its affiliates and each other person, if any, who controls any thereof, against any loss, liability, claim, damage and expense
whatsoever (including, but not limited to, any and all expenses whatsoever reasonably incurred in investigating, preparing or
defending against any litigation commenced or threatened or any claim whatsoever) arising out of or based upon any false representation
or warranty or breach or failure by the Lender to comply with any of the provisions of Section 8 of this Loan Agreement.


 


10.
Default. A default will occur under the Note (a “Default”) upon the failure of PESI to pay within 30 days when
due any interest on or principal of the Note or any renewals or modifications thereof.


 


11.
Remedies. Upon a Default (as defined in paragraph 9, above), the Lender will have the option to declare the Note and any
renewals, extensions or modifications thereof to be immediately due and payable whereupon the Note or any renewals or modifications
thereof shall become forthwith due and payable upon written demand, and the Lender will thereafter have the right to elect by
written election delivered to PESI to receive in full and complete satisfaction of all of PESI’s obligations under the Note
either:


 





	 	(a)	the
    cash amount equal to the sum of the unpaid principal balance owing under the Note and all accrued and unpaid interest thereon
    (the “Payoff Amount”); or
	 	 	 
	 	(b)	the
    number of whole shares of PESI Common Stock (the “Payoff Shares”) determined by dividing the Payoff Amount by
    the dollar amount equal to the closing bid price of PESI’s Common Stock on the date immediately prior to the date of
    Default of this Note, as reported or quoted on the primary nationally recognized exchange or automated quotation system on
    which the Common Stock is listed; provided however, that for the purposes of determining the amount of Payoff Shares the dollar
    amount of such closing bid price shall not be less than $3.51, being the closing bid price for PESI Common Stock as disclosed
    on Nasdaq.com immediately preceding the signing of this Loan Agreement.




 





The
Lender’s option to elect the Payoff Amount or the Payoff Shares is mutually exclusive, and the Lender may not elect a combination
of the Payoff Amount and the Payoff Shares. If the Lender elect to receive the Payoff Shares, the issuance of the Payoff Shares
will be subject to compliance with the regulations of the primary nationally recognized exchange or automated quotation system
on which the Common Stock is listed, the then applicable federal and state securities laws and the Lender providing, as of the
issuance of the Payoff Shares, substantially the same representations and warranties as set forth in paragraph 8 of this Loan
Agreement. If issued, the Payoff Shares will not be registered and the Lender will not be entitled to registration rights with
respect to the Payoff Shares. Notwithstanding any other provision of this Loan Agreement, the Note, or the Warrants, the aggregate
number of Shares, Warrant Shares, and Payoff Shares that are or will be issued to the Lender pursuant to this Loan Agreement,
the Note, and the Warrants, together with the aggregate shares of PESI Common Stock and other PESI voting securities owned by
the Lender as of the date of issuance of the Payoff Shares, shall not exceed the lesser of: (a) the number of shares of PESI Common
Stock equal to 14.9% of the number of shares of PESI Common Stock issued and outstanding as of the date immediately prior to the
Default, less the number of shares of PESI Common Stock owned by the Lender immediately prior to the date of such Default plus
the number of shares of PESI Common Stock that may be acquired by the Lender under warrants and/or options outstanding immediately
prior to the date of such Default; or (b) 14.9% of the voting power of all PESI voting securities issued and outstanding as of
the date of the Default, less the voting power of shares of PESI voting securities held by the Lender as of the date of such Default
plus the voting power of shares of PESI Common Stock that may be acquired by the Lender under warrants and/or options outstanding
immediately prior to the date of such Default. Subject to the terms of this Loan Agreement, PESI will issue the Common Stock certificate
representing 100% of the Payoff Shares to Lender. PESI will not be obligated to issue any fractional shares of Common Stock as
Payoff Shares.

    the parties hereto and their respective successors and assigns, any rights or remedies under or by reason of this Loan Agreement.
	 	 	 
	 	12.9	Maximum
    Legal Rate of Interest. Notwithstanding any other provisions of this Loan Agreement or the Note to the contrary, the total
    interest charges incurred by PESI pursuant to the Note shall not exceed the maximum legal rate of interest under Washington
    law. If the holder of the Note shall ever be entitled to receive, collect or apply, as interest on the Loan, any amount in
    excess of the maximum legal rate of interest permitted to be charged by applicable law, and, in the event any holder of the
    Note ever receives, collects or applies, as interest, any such excess, such amount which would be excessive interest shall
    be applied to the reduction of the unpaid principal balance of the applicable Note, and if the principal balance is paid in
    full, any remaining excess shall be forthwith paid to PESI. In determining whether or not the interest paid or payable under
    any specific contingency exceeds the highest lawful rate, PESI and the Lender shall, to the maximum extent permitted, under
    applicable law: (a) characterize any non-principal payment as an expense, fee or premium rather than as interest; (b) exclude
    voluntary prepayments and the effects thereof; (c) “spread” the total amount of interest on the Note throughout
    the entire term of the Note so that the interest rate is uniform throughout the entire term of the Note.
	 	 	 
	 	12.10	No
    Responsibility of Lender. Notwithstanding any term or provision of this Loan Agreement or the Note, the Lender shall not
    have any right as to management, conduct or operation of the business and affairs of PESI or any of their subsidiaries.
	 	 	 
	 	12.11	Counterparts;
    Facsimile Signatures. This Loan Agreement may be executed in one or more counterparts, all of which shall be considered
    one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties
    and delivered to the other party, it being understood that all parties need not sign the same counterpart. Delivery by facsimile
    to counsel for the other party of a counterpart executed by a party shall be deemed to meet the requirements of the previous
    sentence.
	 	 	 
	 	12.12	Assignment.
    No party may assign either this Loan Agreement or any of its rights, interests, or obligations hereunder without the prior
    written approval of the other parties. This Loan Agreement shall be binding upon and shall inure to the benefit of the parties
    hereto and their respective successors and permitted assigns.
	 	 	 
	 	12.13	Attorneys’
    Fees. The substantially prevailing party in any situation or suit to enforce any provision of this agreement shall be
    entitled to reasonable attorney’s fees and any costs incurred, including, without limitation, costs of collection, enforcing
    a judgment and on appeal or in any bankruptcy proceeding (including efforts to modify or vacate any automatic stay or injunction).
