Document Content:

any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto. (c) 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.

(d) Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise
hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or
reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant
to sales registered or exempted under the Securities Act.

Section 5. Registration Rights

(a) Demand
Registration.

i. Grant of Right. The Company,
upon written demand (“Initial Demand Notice”) of the Holder(s) of at least 51% of the Warrant Shares (“Majority
Holders”), agrees to register on two occasions only (each, a “Demand Registration”) under the Securities
Act all or any portion of the Warrant Shares requested by the Majority Holders in the Initial Demand Notice (the “Registrable
Securities”). On such occasion, the Company will file a registration statement covering the Registrable Securities within 60
days after receipt of the Initial Demand Notice and to have such registration statement declared effective as soon as possible thereafter.
A demand for registration may be made at any time during which the Majority Holders hold any of the Warrant Shares. Notwithstanding the
foregoing, the Company shall not be required to effect a registration pursuant to this Section 5 (a): (A) with respect to securities that
are not Registrable Securities; (B) during any Scheduled Black-Out Period; (C) if the aggregate offering price of the Registrable Securities
to be offered is less than $250,000, unless the Registrable Securities to be offered constitute all of the then-outstanding Registrable
Securities; or (D) within 180 days after the effective date of a prior registration in respect of the Common Stock, including a Demand
Registration (or, in the event that Holders were prevented from including any Registrable Securities requested to be included in a Piggyback
Registration pursuant to Section 5(b), within 90 days after the effective date of such prior registration in respect of the Common Stock).
For purposes of this Agreement, a “Scheduled Black-Out Period” shall mean the periods from and including the day that
is ten days prior to the last day of a fiscal quarter of the Company to and including the day that is two days after the day on which
the Company publicly releases its earnings for such fiscal quarter. The Initial Demand Notice shall specify the number of shares of Registrable
Securities proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all holders of the Warrant
Shares of the demand within ten days from the date of the receipt of any such Initial Demand Notice. Each holder of the Warrant Shares
who wishes to include all or a portion of such holder’s Warrant Shares in the Demand Registration (each such holder including shares
of Registrable Securities in such registration, a “Demanding Holder”) shall so notify the Company within 15 days after
the receipt by the holder of the notice from the Company. Upon any such request, the Demanding Holders shall be entitled to have their
Warrant Shares included in the Demand Registration. The term of the Demand Registration shall not be more than five years from the date
of effectiveness of the Registration Statement.

ii. Effective Registration. A registration
will not count as a Demand Registration until the registration statement filed with the Commission with respect to such Demand Registration
has been declared effective and the Company has complied with all of its obligations under this Warrant with respect thereto.

iii. Terms. In connection with
the first Demand Registration, the Company shall bear all fees and expenses attendant to registering the Registrable Securities, including
the reasonable expenses of one legal counsel selected by the Holders to represent them in connection with the sale of the Registrable
Securities. In connection with the second Demand Registration, the Holders shall bear all fees and expenses attendant to registering the
Registrable Securities including the reasonable expenses of the Company’s legal counsel. The Company agrees to qualify or register
the Registrable Securities in such states as are reasonably requested by the Majority Holder(s); provided, however, that in no event shall
the Company be required to register the Registrable Securities in a state in which such registration would cause (i) the Company to be
obligated to qualify to do business in such state, or would subject the Company to taxation as a foreign corporation doing business in
such jurisdiction or (ii) the principal shareholders of the Company to be obligated to escrow their shares of Common Stock of the Company.
The Company shall cause any registration statement filed pursuant to the demand rights granted under Section 5(a)(iii) to remain effective
until all Registrable Securities are sold.

iv. Notwithstanding the foregoing, if
the Board of Directors of the Company determines in its good faith judgment that the filing of a registration statement in connection
with a Demand Registration (i) would be seriously detrimental to the Company in that such registration would interfere with a material
corporate transaction or (ii) would require the disclosure of material non-public information concerning the Company that at the time
is not, in the good faith judgment of the Board of Directors, in the best interests of the Company to disclose and is not, in the opinion
of the Company’s counsel, otherwise required to be disclosed, then the Company shall have the right to defer such filing for the
period during which such registration would be seriously detrimental under clause (i) or would require such disclosure under clause (ii);
provided, however, that (x) the Company may not defer such filing for a period of more than 90 days after receipt of any demand by the
Holders and (y) the Company shall not exercise its right to defer a Demand Registration more than once in any 12-month period. The Company
shall give written notice of its determination to the Holders to defer the filing and of the fact that the purpose for such deferral no
longer exists, in each case, promptly after the occurrence thereof.

(b) Piggy-Back
Registration.
