	 	Expiration Date:	February 19, 2022

B.O.S. BETTER ONLINE SOLUTIONS LTD., a
company organized and existing under the laws of the State of Israel (the “Company”), hereby certifies that,
for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, YA II PN, Ltd. (the “holder”),
or its permitted assigns hereunder, is entitled, subject to the terms set forth below, to purchase from the Company upon surrender
of this Warrant, at any time or times on or after the date hereof, but not after 11:59 P.M. Eastern Time on the Expiration
Date (as defined herein) up 100,000 fully paid and nonassessable Ordinary Shares (as defined herein) of the Company (the “Warrant
Shares”) at the exercise price per share provided in Section 1(b) below or as subsequently adjusted; provided, however,
that in no event shall the holder be entitled to exercise this Warrant for a number of Warrant Shares in excess of that number
of Warrant Shares which, upon giving effect to such exercise, would cause the aggregate number of Ordinary Shares beneficially
owned by the holder and its affiliates to exceed 4.99% of the outstanding Ordinary Shares following such exercise (however, such
restriction may be waived by the holder (but only as to itself and not to any other holder) upon not less than 65 days prior notice
to the Company). For purposes of the foregoing proviso, the aggregate number of Ordinary Shares beneficially owned by the holder
and its affiliates shall include the number of Ordinary Shares issuable upon exercise of this Warrant with respect to which the
determination of such proviso is being made, but shall exclude Ordinary Shares which would be issuable upon (i) exercise of
the remaining, unexercised Warrants beneficially owned by the holder and its affiliates and (ii) exercise or conversion of
the unexercised or unconverted portion of any other securities of the Company beneficially owned by the holder and its affiliates
(including, without limitation, any convertible notes or preferred stock) subject to a limitation on conversion or exercise analogous
to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership
shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this Warrant,
in determining the number of outstanding Ordinary Shares a holder may rely on the number of outstanding Ordinary Shares as reflected
in (1) the Company’s most recent Form 20-F, (2) a more recent public announcement by the Company or (3) any other notice
by the Company or its transfer agent setting forth the number of Ordinary Shares outstanding. Upon the written request of any holder,
the Company shall promptly, but in no event later than 1 Business Day following the receipt of such notice, confirm in writing
to any such holder the number of Ordinary Shares then outstanding. In any case, the number of outstanding Ordinary Shares shall
be determined after giving effect to the exercise of Warrants (as defined below) by such holder and its affiliates since the date
as of which such number of outstanding Ordinary Shares was reported.

Shares to which the holder shall be entitled pursuant to such request. The Warrant Shares shall be issued with a legend unless
they are subject to an effective and current Registration Statement or they are being transferred pursuant to an exemption from
such registration requirements, the availability of which is confirmed in an opinion of counsel acceptable to the Company’s
Transfer Agent. Upon delivery of the Exercise Notice pursuant to the notice delivery provisions in Section 9 herein and Aggregate

balance account with the Transfer Agent for such number of Warrant Shares to which the holder is entitled upon the holder’s

holder on a timely basis and to which the holder is entitled, and (B) the Closing Bid Price of the Ordinary Shares for the trading

that a new Warrant be issued, the Company fails to deliver a new Warrant to the holder for the number of Warrant Shares to which

however, that by making the representations herein, the holder does not agree to hold this Warrant or any of the Warrant Shares
for any minimum or other specific term and reserves the right to dispose of this Warrant and the Warrant Shares at any time in

Section 7. Adjustment
of Warrant Exercise Price. The Warrant Exercise Price of this Warrant shall be adjusted from time to time as follows:

 

(a) RESERVED.

 

(b) Adjustment
of Warrant Exercise Price upon Subdivision or Combination of Ordinary Shares. If the Company at any time after the date of
issuance of this Warrant subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of
its outstanding Ordinary Shares into a greater number of shares, any Warrant Exercise Price in effect immediately prior to such
subdivision will be proportionately reduced and the number of Ordinary Shares obtainable upon exercise of this Warrant will be
proportionately increased. If the Company at any time after the date of issuance of this Warrant combines (by combination, reverse
stock split or otherwise) one or more classes of its outstanding Ordinary Shares into a smaller number of shares, any Warrant Exercise
Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares issuable
upon exercise of this Warrant will be proportionately decreased. Any adjustment under this Section 7(b) shall become effective
at the close of business on the date the subdivision or combination becomes effective.

 

    7

     

    

 

(c) 

 

(d) Voluntary

setting forth in reasonable detail, and certifying, the calculation of such adjustment.

Company will give written notice to the holder of this Warrant at least ten (10) days prior to the date on which the Company closes
its books or takes a record (A) with respect to any dividend or distribution upon the Ordinary Shares, (B) with respect
to any pro rata subscription offer to holders of Ordinary Shares or (C) for determining rights to vote with respect to any
Organic Change (as defined below), dissolution or liquidation, provided that such information shall be made known to the public
prior to or in conjunction with such notice being provided to such holder.

 

(iii) The
Company will also give written notice to the holder of this Warrant at least 10 days prior to the date on which any Organic Change,
dissolution or liquidation will take place, provided that such information shall be made known to the public prior to or in conjunction
with such notice being provided to such holder.

Change” shall mean any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially
all of the Company’s assets to another Person or other transaction in each case which is effected in such a way that holders
of Ordinary Shares are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect
to or in exchange for Ordinary Shares. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen,

GUARANTY

 

This Guaranty is made
as of February 19, 2020, by B.O.S. Better Online Solutions Ltd. and BOS-Odem Ltd. (each, a “Guarntor”
and collectively, the “Guarantors”), in favor of YA II PN, LTD. (“YA II”) with respect
to all obligations of RUBY-TECH INC. (the “Debtor”) owed to YA II.

 

RECITALS

 

WHEREAS, YA II and
Debtor are entering into a Note Purchase Agreement (the “Purchase Agreement”) of even date herewith pursuant
to which YA II will be purchasing a promissory note (the “Note”) from the Debtor of up to an aggregate of $600,000;

 

WHEREAS, it is a condition
of the Purchase Agreement and YA II’s obligation to purchase the Note from the Debtor that Guarantors jointly and severally
guaranty all of the Debtor’s obligations under the Purchase Agreement and the Note (collectively, the “Transaction
Documents”) by to YA II; and

 

WHEREAS, the Debtor
is wholly owned by BOS-Odem Ltd. (“BOS-Odem”), which itself is wholly ownderd by B.O.S. Better Online Soluctions
Ltd., and through such relationships, each Guarantor will benefit, directly or indirectly, from the Debtor entering into the Transaction
Documents and from the extension of credit YA II will make to Debtor;

 

NOW, THEREFORE, for
good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each Guarantor covenants and agrees
as follows:

 

1. Guaranty
of Payment and Performance. Each Guarantor, jointly and severally, hereby guarantees to the YA II the full, prompt and
unconditional payment when due (whether at maturity, by acceleration or otherwise), and the performance, of all liabilities, agreements
and other obligations of the Debtor to the YA II pursuant to the Transaction Documents, whether direct or indirect, absolute or
contingent, due or to become due, secured or unsecured, now existing or hereafter arising or acquired, together with all interest
and costs of collection, compromise or enforcement, including without limitation reasonable attorneys’ fees, incurred with
respect to any such obligations or this Guaranty, or with respect to a proceeding under the federal bankruptcy laws or any insolvency,
receivership, arrangement or reorganization law or an assignment for the benefit of YA II concerning Debtor or any Guarantor (all
the foregoing, collectively, the “Obligations”). This Guaranty is an absolute, unconditional and continuing
guaranty of the full and punctual payment and performance of the Obligations and not of their collectability only and is in no
way conditioned upon any requirement that the YA II first attempt to collect any of the Obligations from the Debtor or resort to
any security or other means of obtaining their payment. Should the Debtor default in the payment or performance of any of the Obligations,
the obligations of any Guarantor hereunder shall become immediately due and payable to the YA II, without demand or notice of any
nature, all of which are expressly waived by each Guarantor.

 

2. Unlimited
Guaranty. The liability of each Guarantor hereunder shall be unlimited.

 

     

     

    

 

3. Waivers by
each Guarantor; YA II’s Freedom to Act. The Guarantor hereby agrees that the Obligations will be paid and performed
strictly in accordance with their terms regardless of any law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the YA II with respect thereto. The Guarantor waives presentment, demand, protest,
notice of acceptance, notice of Obligations incurred and all other notices of any kind, all defenses that may be available by virtue
of any valuation, stay, moratorium law or other similar law now or hereafter in effect, any right to require the marshalling of
assets of the Debtor, and all suretyship defenses generally. Without limiting the generality of the foregoing, the Guarantor agrees
to the provisions of any instrument evidencing, securing or otherwise executed in connection with any Obligation and agrees that
the obligations of each Guarantor hereunder shall not be released or discharged, in whole or in part, or otherwise affected by
(i) the failure of the YA II to assert any claim or demand or to enforce any right or remedy against the Debtor; (ii) any extensions
or renewals of, or alteration of the terms of, any Obligation or any portion thereof; (iii) any rescissions, waivers, amendments
or modifications of any of the terms or provisions of any agreement evidencing, securing or otherwise executed in connection with
any Obligation; (iv) the substitution or release of any entity primarily or secondarily liable for any Obligation; (v) the adequacy
of any rights the YA II may have against any collateral or other means of obtaining repayment of the Obligations; (vi) the impairment
of any collateral securing the Obligations, including without limitation the failure to perfect or preserve any rights the YA II
might have in such collateral or the substitution, exchange, surrender, release, loss or destruction of any such collateral; (vii)
failure to obtain or maintain a right of contribution for the benefit of each Guarantor; (viii) errors or omissions in connection
with the YA II’s administration of the Obligations (except behavior constituting gross negligence or bad faith); or (ix)
any other act or omission that might in any manner or to any extent vary the risk of any Guarantor or otherwise operate as a release
or discharge of any Guarantor, all of which may be done without notice to any Guarantor.

 

4. Unenforceability
of Obligations Against Debtor. If for any reason the Debtor are under no legal obligation to discharge any of the Obligations,
or if any of the Obligations have become irrecoverable from the Debtor by operation of law or for any other reason, this Guaranty
shall nevertheless be binding on each Guarantor to the same extent as if each Guarantor at all times had been the principal obligor
on all such Obligations. In the event that acceleration of the time for payment of the Obligations is stayed upon the insolvency,
bankruptcy or reorganization of the Debtor, or for any other reason, all such amounts otherwise subject to acceleration under the
terms of any agreement evidencing, securing or otherwise executed in connection with any Obligation shall be immediately due and
payable by each Guarantor.

 

5. Subrogation;
Subordination. Until the payment and performance in full of all Obligations and any and all obligations of the Debtor to YA
II, each Guarantor shall not exercise any rights against the Debtor arising as a result of payment by each Guarantor hereunder,
by way of subrogation or otherwise, and will not prove any claim in competition with the YA II in respect of any payment hereunder
in bankruptcy or insolvency proceedings of any nature; each Guarantor will not claim any set-off or counterclaim against the Debtor
in respect of any liability of each Guarantor to the Debtor; and each Guarantor waives any benefit of and any right to participate
in any collateral that may be held by the YA II. Each Guarantor agrees that after the occurrence of any default in the payment
or performance of the Obligations, each Guarantor will not demand, sue for or otherwise attempt to collect any such indebtedness
of the Debtor to each Guarantor until the Obligations shall have been paid in full. If, notwithstanding the foregoing sentence,
each Guarantor shall collect, enforce or receive any amounts in respect of such indebtedness, such amounts shall be collected,
enforced and received by each Guarantor as trustee for the YA II and be paid over to the YA II on account of the Obligations without
affecting in any manner the liability of each Guarantor under the other provisions of this Guaranty.

 

    2

     

    

 

7. Termination;
Reinstatement. This Guaranty is irrevocable and shall exipre upon the repayment in full of all amounts owed by Debtor under
the Note. This Guaranty shall be reinstated if at any time any payment made or value received with respect to an Obligation is
rescinded or must otherwise be returned by the YA II upon the insolvency, bankruptcy or reorganization of the Debtor, or otherwise,
all as though such payment had not been made or value received.

 

8. Successors
and Assigns. This Guaranty shall be binding upon each Guarantor, its successors and assigns, and shall inure to the benefit
of and be enforceable by the YA II and the YA II’s shareholders, officers, directors, agents, successors and assigns.

 

9. Amendments
and Waivers. No amendment or waiver of any provision of this Guaranty nor consent to any departure by each Guarantor therefrom
shall be effective unless the same shall be in writing and signed by the YA II. No failure on the part of the YA II to exercise,
and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of
any right hereunder preclude any other or further exercise thereof or the exercise of any other right.

 

10. Notices.
All notices and other communications called for hereunder shall be made in writing and, unless otherwise specifically provided
herein, shall be deemed to have been duly made or given when delivered by hand or mailed first class mail postage prepaid or, in
the case of telecopied notice, when transmitted, receipt confirmed, addressed as follows: if to any Guarantor, at the address or
e-mail address set forth below, and if to the YA II, at 1012 Springfield Avenue, Mountainside, New Jersey 07092, or at such address
as either party may designate in writing.

 

11. Governing
Law; Consent to Jurisdiction. This Guaranty is intended to take effect as a sealed instrument and shall be governed by,
and construed in accordance with, the laws of the State of New York (excluding the laws applicable to conflicts or choice of law).
Each of the parties consents to the jurisdiction of the state courts of the State of New York and the U.S. District Court
for the District of New York sitting in Manhattan, in connection with any dispute arising under this Note and hereby waives, to
the maximum extent permitted by law, any objection, including any objection based on forum non conveniens to the bringing of any
such proceeding in such jurisdictions.
