 a)       Upon
delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered
Holder at the address of the Holder appearing on the books of the Company) of a duly executed notice of exercise (the “Notice
of Exercise”) in substantially the form of the Notice of Exercise Form annexed hereto and the aggregate Exercise Price
for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States
bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise,
the Holder shall be entitled to Exercise the rights represented by this Warrant, in whole or in part, to acquire Warrant Shares
at any time or times on or before the Termination Date by facsimile. Notwithstanding anything herein to the contrary (although
the Holder may surrender the Warrant to, and receive a replacement Warrant from, the Company), the Holder shall not be required
to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder
and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation
within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this
Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of
lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant
Shares purchased. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date
of such purchases. In the case of a partial exercise of this Warrant, the Holder may request that the Company deliver to the Holder
a certificate representing such new warrant, with terms identical in all respects to this Warrant (except that such new warrant
shall be exercisable into the number of Warrant Shares with respect to which this Warrant shall remain unexercised); provided,
however, that the Holder shall be entitled to exercise all or any portion of such new warrant, regardless of whether the Company
has actually issued such new warrant or delivered to the Holder a certificate thereof. The Company shall deliver any objection
to any Notice of Exercise Form within one (1) Trading Day of delivery of such notice. The Holder and any assignee, by acceptance
of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion
of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than
the amount stated on the face hereof. 

   

    2 

     

    

   

 b)       Exercise
Price. The exercise price per share of the Warrant Shares under this Warrant shall be $0.50 subject to adjustment hereunder
(the “Exercise Price”). 

   

 c)       Cashless
Exercise. This Warrant may also be exercised at the Holder’s election, in whole or in part, at such time by means of
a “cashless exercise.” The Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained
by dividing [(A-B) x (X)] by (A), where: 

   

 (A) =   the
VWAP on the Trading Day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless
exercise,” as set forth in the applicable Notice of Exercise; 

   

 (B) =    the
Exercise Price of this Warrant, as adjusted hereunder; and 

   

 (X) =  
the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant
if such exercise were by means of a cash exercise rather than a cashless exercise. 

   

 “VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then
listed or quoted Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding
date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (or other reliable
source) based on a Trading Day from 9:30 a.m. (New York City time) (or such other time as the Trading Market publicly announces
is the official open of trading) to 4:00 p.m. (New York City time) (or such other time as the Trading Market publicly announces
is the official close of trading), (b) if no daily volume weighted average prices are reported by Bloomberg (or other reliable
source), the average of the highest closing bid price and the lowest closing ask price of any of the market makers for such security
as reported in the “pink sheets” by OTC Markets LLC, or (c) in all other cases, the fair market value of a share of
Common Stock as mutually determined by the Company and Holder. 

   

 d)         Mechanics
of Exercise. 

 

   

    3 

     

    

   

 i.          Delivery
of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the Transfer Agent (“Transfer
Agent” means the transfer agent employed by the Company from time to time, for its Common Stock) to the Holder by physical
delivery to the address specified by the Holder in the Notice of Exercise by the date that is three (3) Trading Days after the
date of delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”). Notwithstanding
the above, Warrant Shares may be issued and delivered in uncertificated form (with a notice of share issuance delivered to Holder)
and maintained in electronic form on the transfer agent’s books and records. The Warrant Shares shall be deemed to have
been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record
of such shares for all purposes, as of the date of delivery to the Company of the Notice of Exercise. 

   

 ii.         Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder
and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant
Shares (or delivery of notice of issuance, if shares are issued in uncertificated form), deliver to the Holder a new Warrant evidencing
the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all
other respects be identical with this Warrant. 

   

 iii.        No
Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise
of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the
Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction
multiplied by the Exercise Price or round up to the next whole share. 

   

 iv.        Charges,
Taxes and Expenses. Issuance of certificates for Warrant Shares shall be made without charge to the Holder for any issue or
transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall
be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names as may be directed
by the Holder. 

   

 v.         Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of
this Warrant, pursuant to the terms hereof. 

   

 Section 3.           Certain
Adjustments. 

   

 a)         Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise
makes a distribution or distributions of shares of its Common Stock to the record holders of Common Stock (which, for avoidance
of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding
shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares
of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of the Common Stock any shares of
capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall
be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which
the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares
issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant
shall remain unchanged in the case of an exercise for Common Stock only. In the event that any adjustment of the Exercise Price
required herein results in a fraction of a cent, the Exercise Price shall be rounded down to the nearest one hundredth of a cent.
Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination
of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date
in the case of a subdivision, combination or reclassification. 

   

    4 

     

    

   

 b)         Pro
Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common
Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants
to subscribe for or purchase any security of the Company other than the Common Stock (which shall be subject to Section 3(b))
(a “Distribution”), then in each such case the Holder shall be entitled to participate in such Distribution
to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock
acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including, without limitation,
the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such
record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation
in such Distribution (provided, however, to the extent that the Holder’s right to participate in any such Distribution would
result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such
Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to
such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if
ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation). To the extent that this
Warrant has not been exercised at the time of such Distribution, such portion of the Distribution shall be held in abeyance for
the benefit of the Holder until the Holder has exercised this Warrant. 

   

 c)         Fundamental
Transaction. Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly,
in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of
the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is
effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in
one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without
limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person
acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person
or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share
purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent conversion
of this Note, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion
immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section 2.(e) on the
conversion of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the Company,
if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as
a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is convertible
immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2.(e) on the conversion of this
Warrant). For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply
to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one (1) share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Conversion Price among the Alternate Consideration
in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of
Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the
Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Warrant following
such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is
not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant
and the other Transaction Documents in accordance with the provisions of this Section 3(c) pursuant to written agreements in form
and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental
Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is convertible for
a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of
Common Stock acquirable and receivable upon conversion of this Warrant (without regard to any limitations on the conversion of
this Warrant) prior to such Fundamental Transaction, and with a conversion price which applies the conversion price hereunder
to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental
Transaction and the value of such shares of capital stock, such number of shares of capital stock and such conversion price being
for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction),
and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction,
the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead
to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the
Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been named
as the Company herein. The foregoing provisions shall similarly apply to successive Fundamental Transactions of a similar nature
by any such successor entity. 

   

    5 

     

    

   

 d)         Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be.
For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall
be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding. 

   

 e)         Notice
to Holder. 

   

 Whenever the Exercise
Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly mail to the Holder a notice setting
forth the Exercise Price after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth
a brief statement of the facts requiring such adjustment. 

   

 f)          Adjustments.
In the event that at any time, as a result of an adjustment made pursuant to this Section 3, the Holder shall, upon exercise of
this Warrant, become entitled to receive securities or assets (other than Common Stock) then, wherever appropriate, all references
herein to shares of Common Stock shall be deemed to refer to and include such shares and/or other securities or assets; and thereafter
the number of such shares and/or other securities or assets shall be subject to adjustment from time to time in a manner and upon
terms as nearly equivalent as practicable to the provisions of this Section 3. 

   

    6 

     

    

   

 Section 4.           Transfer
of Warrant. 

   

 a)         Transferability.
Subject to compliance with any applicable securities laws, this Warrant and all rights hereunder (including, without limitation,
any registration rights) are transferable, in whole but not in part, only to an Affiliate of the Holder and upon surrender of
this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall
execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination
or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled. The Warrant, if properly assigned in accordance
herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued. 

   

 b)         Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered
Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder,
and for all other purposes, absent actual notice to the contrary. 

   

 Section 5.          
Miscellaneous. 

   

 a)         No
Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights
as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(a)(i). 

   

 b)         Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case
of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate,
if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation,
in lieu of such Warrant or stock certificate. 

   

 c)         Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required
or granted herein shall not be a Trading Day, then, such action may be taken or such right may be exercised on the next succeeding
Trading Day. 

   

 d)         Authorized
Shares. 

   

 i.          The
Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights
under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers
who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be
necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation,
or of any requirements of the Principal Market upon which the Common Stock may be listed. 

    

    7 

     

    

   

 ii.          Except
and to the extent as waived or consented to by the Holder, the Company shall not by any action to avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such
terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in
this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (i) take all such action as
may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares
upon the exercise of this Warrant and (ii) use commercially reasonable efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its
obligations under this Warrant. 

   

 iii.        Before
taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or
in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be
necessary from any public regulatory body or bodies having jurisdiction thereof. 

   

 e)         Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined
in accordance with the laws of the state of Nevada (excluding its choice of law rules). 

   

 f)          Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if Holder does not utilize cashless
exercise and Rule 144 is available, will have restrictions upon resale imposed by state and federal securities laws. 

   

 g)         Nonwaiver.
No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of
such right or otherwise prejudice the Holder’s rights, powers or remedies. 

   

 h)         Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered
in accordance with the notice provisions of this Warrant. 

   

 i)          Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase
Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder
for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company
or by creditors of the Company. 

   

 j)          Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled
to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert
the defense in any action for specific performance that a remedy at law would be adequate. 

   

 k)         Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns
of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and
shall be enforceable by the Holder or holder of Warrant Shares. 

   

 l)          Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder. 

   

    8 

     

    

   

 m)        Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant. 

   

 n)         Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of
this Warrant.

 PERSONAL GUARANTY
OF PERFORMANCE 

   

 This Personal Guaranty of Performance (this “Guaranty”)
is executed as of January 2, 2018, by Milton C. Ault, III __________ (the “Guarantor”), for the benefit of TVT CAPITAL,
LLC (“Buyer”). 

   

   

 Capitalized terms used herein, but not defined, shall have
the meanings assigned to them in the Purchase Agreement (as hereinafter defined). 

   

 RECITALS 

   

 A.
Pursuant to that Agreement for the Purchase and Sale of Future Receipts (the “Purchase Agreement”), dated of even
date herewith, between Buyer and_______________________(“Seller”), Buyer has purchased Future Receipts of Seller. 

   

 B.
Buyer is not willing to enter into the Purchase Agreement unless Guarantor irrevocably, absolutely and unconditionally guarantees
prompt and complete performance to Buyer of all of the obligations of Seller; and 

   

 C.
Guarantor will directly benefit from Buyer and Seller entering into the Purchase Agreement. 

   

 AGREEMENT 

   

 As an inducement to Buyer to purchase the Future
Receipts identified in the Purchase Agreement, and for other good and valuable consideration, the receipt and legal sufficiency
of which are hereby acknowledged, Guarantor does hereby agree as follows: 

   

 1.    Defined
Terms: All capitalized terms used and not otherwise defined herein shall have the meanings assigned to such terms in the Purchase
Agreement. 

   

 2.    Guaranty
of Obligations: Guarantor hereby irrevocably, absolutely and unconditionally guarantees to Buyer prompt and complete performance
of all of Seller’s obligations under the Purchase Agreement. 

   

 3.    Guarantor’s
Other Agreements: Guarantor will not dispose, convey, sell or otherwise transfer, or cause Seller to dispose, convey, sell
or otherwise transfer, any material business assets of Seller without the prior written consent of Buyer, which may be withheld
for any reason, until receipt of the entire Purchased Amount. Guarantor hereby agrees to pay all costs and attorney’s fees
incurred by Buyer in connection with any actions commenced by Buyer to enforce its rights or incurred in any action to defend
its performance under the Purchase Agreement and this Guaranty. This Guaranty is binding upon Guarantor, and Guarantor’s
heirs, legal representatives, successors and assigns. If there is more than one Guarantor, the obligations of the Guarantors hereunder
shall be joint and several. The obligation of Guarantor shall be unconditional and absolute, regardless of the unenforceability
of any provision of any agreement between Seller and Buyer, or the existence of any defense, setoff or counterclaim which Seller
may assert. Buyer is hereby authorized, without notice or demand and without affecting the liability of Guarantor hereunder, to
at any time renew or extend Seller’s obligations under the Purchase Agreement or otherwise modify, amend or change the terms
of the Purchase Agreement. Guarantor is hereby notified that a negative credit report reflecting on his/her credit record may
be submitted to a credit reporting agency if the terms of this Guaranty are not honored by the Guarantor. 

   

 4.    Waiver;
Remedies: No failure on the part of Buyer to exercise, and no delay in exercising, any right under this Guaranty shall operate
as a waiver, nor shall any single or partial exercise of any right under this Guaranty preclude any other or further exercise
of any other right. The remedies provided in this Guaranty are cumulative and not exclusive of any remedies provided by law or
equity. In the event that Seller fails to perform any obligation under the Purchase Agreement, Buyer may enforce its rights under
this Guaranty without first seeking to obtain performance for such default from Seller or any other guarantor. 

   

 5.    Acknowledgment
of Purchase: Guarantor acknowledges and agrees that the Purchase Price paid by Buyer to Seller in exchange for the Purchased
Amount is a purchase of the Purchased Amount and is not intended to be treated as a loan or financial accommodation from Buyer
to Seller. Guarantor specifically acknowledges Buyer is not a lender, bank or credit card processor, and that Buyer has not offered
any loans to Seller, and Guarantor waives any claims or defenses of usury in any action arising out of this  Guaranty. Guarantor
acknowledges the Purchase Price paid to Seller is good and valuable consideration for the sale of the Purchased Amount of Future
Receipts.

regard to principles of conflicts of law. Except as provided in Section 9 of this Guaranty, Guarantor submits to the exclusive
jurisdiction and venue of the state or federal courts having jurisdiction over any city/county in the State of New York of any
claims or actions arising, directly or indirectly, out of or related to this Guaranty. The parties stipulate that the venues referenced
in this Agreement are convenient. The parties further agree that the mailing by certified or registered mail, return receipt requested,
of any process required by any such court will constitute valid and lawful service of process against them, without the necessity
for service by any other means provided by statute or rule of court, but without invalidating service performed in accordance
with such other provisions. 

   

 7.    JURY WAIVER: THE PARTIES
WAIVE THE RIGHT TO A TRIAL BY JURY IN ANY COURT IN ANY SUIT, ACTION OR PROCEEDING ON ANY MATTER ARISING IN CONNECTION WITH OR
IN ANY WAY RELATED TO THE TRANSACTIONS OF WHICH THIS AGREEMENT IS A PART OR ITS ENFORCEMENT, EXCEPT WHERE SUCH WAIVER IS PROHIBITED
BY LAW OR DEEMED BY A COURT OF LAW TO BE AGAINST PUBLIC POLICY. THE PARTIES ACKNOWLEDGE THAT EACH MAKES THIS WAIVER KNOWINGLY,
WILLINGLY AND VOLUNTARILY AND WITHOUT DURESS, AND ONLY AFTER EXTENSIVE CONSIDERATION OF THE RAMIFICATIONS OF THIS WAIVER WITH
THEIR ATTORNEYS. 

   

 8.    CLASS ACTION WAIVER:
THE PARTIES WAIVE ANY RIGHT TO ASSERT ANY CLAIMS AGAINST THE OTHER PARTY AS A REPRESENTATIVE OR MEMBER IN ANY CLASS OR REPRESENTATIVE
ACTION, EXCEPT WHERE SUCH WAIVER IS PROHIBITED BY LAW OR DEEMED BY A COURT OF LAW TO BE AGAINST PUBLIC POLICY. TO THE EXTENT EITHER
PARTY IS PERMITTED BY LAW OR COURT OF LAW TO PROCEED WITH A CLASS OR REPRESENTATIVE ACTION AGAINST THE OTHER, THE PARTIES AGREE
THAT: (I) THE PREVAILING PARTY SHALL NOT BE ENTITLED TO RECOVER ATTORNEYS’ FEES OR COSTS ASSOCIATED WITH PURSUING THE CLASS
OR REPRESENTATIVE ACTION (NOT WITHSTANDING ANY OTHER PROVISION IN THIS AGREEMENT); AND (II) THE PARTY WHO INITIATES OR PARTICIPATES

OR THE GUARANTOR OR THE RELIEF SOUGHT BY SELLER OR THE GUARANTOR IS IMPROPER OR NOT WARRANTED, AS MEASURED BY THE STANDARDS SET
FORTH IN FEDERAL RULE OF PROCEDURE 11(B), THEN BUYER WILL PAY THESE FEES ONLY IF REQUIRED BY THE AAA OR NAF RULES. SELLER AND
THE GUARANTOR AGREE THAT, BY ENTERING INTO THIS AGREEMENT, THEY ARE WAIVING THE RIGHT TO TRIAL BY JURY. BUYER, SELLER OR ANY GUARANTOR
MAY BRING CLAIMS AGAINST ANY OTHER PARTY ONLY IN THEIR INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED
CLASS OR REPRESENTATIVE PROCEEDING. FURTHER, BUYER, SELLER AND ANY GUARANTOR AGREE THAT THE ARBITRATOR MAY NOT CONSOLIDATE PROCEEDINGS
FOR MORE THAN ONE PERSON’S CLAIMS, AND MAY NOT OTHERWISE PRESIDE OVER ANY FORM OF A REPRESENTATIVE OR CLASS PROCEEDING,
AND THAT IF THIS SPECIFIC PROVISION IS FOUND UNENFORCEABLE, THEN THE ENTIRETY OF THIS ARBITRATION CLAUSE SHALL BE NULL AND VOID. 

   

 10.  RIGHT TO OPT OUT OF ARBITRATION:
