(e)Limitations
on Conversion. Notwithstanding anything to the contrary contained in this Note, this Note shall not be convertible by the
Holder hereof, and the Company shall not effect any conversion of this Note or otherwise issue any shares of Common Stock pursuant
hereto, to the extent (but only to the extent) that after giving effect to such conversion or other share issuance hereunder the
Holder (together with its affiliates) would beneficially own in excess of 4.99% (the “Maximum Percentage”)
of the Common Stock. To the extent the above limitation applies, the determination of whether this Note shall be convertible (vis-à-vis
other convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of which such securities
shall be convertible, exercisable or exchangeable (as among all such securities owned by the Holder and its affiliates) shall,
subject to such Maximum Percentage limitation, be determined on the basis of the first submission to the Company for conversion,
exercise or exchange (as the case may be). No prior inability to convert this Note, or to issue shares of Common Stock, pursuant
to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent
determination of convertibility. For purposes of this paragraph, beneficial ownership and all determinations and calculations
(including, without limitation, with respect to calculations of percentage ownership) shall be determined in accordance with Section
13(d) of the Exchange Act. The provisions of this paragraph shall be implemented in a manner otherwise than in strict conformity
with the terms of this paragraph to correct this paragraph (or any portion hereof) which may be defective or inconsistent with
the intended Maximum Percentage beneficial ownership limitation herein contained or to make changes or supplements necessary or
desirable to properly give effect to such Maximum Percentage limitation. The limitations contained in this paragraph shall apply
to a successor Holder of this Note. The holders of Common Stock shall be third party beneficiaries of this paragraph and the Company
may not waive this paragraph without the consent of holders of a majority of its Common Stock. For any reason at any time, upon
the written or oral request of the Holder, the Company shall within one (1) business day confirm orally and in writing to the
Holder the number of shares of Common Stock then outstanding, including by virtue of any prior conversion or exercise of convertible
or exercisable securities into Common Stock, including, without limitation, pursuant to this Note or securities issued pursuant
to the Subscription Agreement. By written notice to the Company, at any time the Holder may increase or decrease the Maximum Percentage
to any other percentage not in excess of 9.99% specified in such notice; provided that any such increase will not be effective
until the 61st day after such notice is delivered to the Company.


 


8.Assignment.
This Note and any shares of Common Stock issued upon conversion of this Note may be offered, sold, assigned or transferred by
the Holder without the consent of the Company; provided, however, that any purchaser, assignee or transferee of this Note shall
agree in writing to be bound by the terms of the Subscription Agreement and this Note.


 


9.Treatment
of Note. To the extent permitted by GAAP, the Company will treat, account and report the Note as debt and not equity for accounting
purposes and with respect to any returns filed with federal, state or local tax authorities. The Holder hereby acknowledges the
foregoing, and agrees not to take any position contrary to such treatment with respect to any tax returns filed by the Holder
unless otherwise required by law.

have been duly given all as set forth in the Subscription Agreement.

right to vote or to consent or to receive notice as a shareholder in respect of meetings of shareholders for the election of members
of the Board of Directors of the Company or any other matters or any rights whatsoever as a shareholder of the Company; and no
dividends shall be payable or accrued in respect of this Note or the interest represented hereby or the shares obtainable hereunder
until, and only to the extent that, this Note shall have been converted.


 


12.Amendments.
The prior written consent of the Holder and the Company shall be required for any change or amendment to this Note.


 


13.Loss
or Mutilation. Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this
Note and, if requested in the case of any such loss, theft or destruction, upon delivery of an indemnity agreement or security
reasonably satisfactory to the Company, or, in the case of any such mutilation, upon surrender and cancellation of this Note,
the Company at its expense will execute and deliver, in lieu hereof, a new Note of like tenor.


 


14.Governing
Law; Consent to Jurisdiction. This Note will be interpreted and the rights and liabilities of the Holder and the Company determined
in accordance with the laws of the State of Illinois, without regard to its conflict of law provisions. Each of the Holder and
the Company hereby irrevocably consents to the exclusive jurisdiction of any state or federal court in Cook County, Illinois,
and consents that all service of process be sent by nationally recognized overnight courier service directed to the Holder at
the Holder’s address set forth in the Subscription Agreement or to the Company at the Company’s address set forth
in the Subscription Agreement and service so made will be deemed to be completed when received by the Holder or the Company, as
applicable. Each of the Holder and the Company acknowledges and agrees that such venue is the most convenient forum for both the
Holder and the Company. Each of the Holder and the Company waives any objection to venue and any objection based on a more convenient
forum in any action instituted under this Note.


 


15.Waiver
of Jury Trial. The Company and the Holder, by accepting this Note, irrevocably waive any and all rights that each may have
to a trial by jury in any action, proceeding or claim of any nature relating to this Note, any documents executed in connection
with this Note or any transaction contemplated in any of such documents. The Company and Holder, by accepting this Note, acknowledge
that the foregoing waiver is knowing and voluntary.


 




    	 	 	 



     

    


 


16.Miscellaneous.
No delay or omission of the Holder to exercise any right or power arising hereunder shall impair any such right or power to be
considered to be a waiver of any such right or power, nor shall the Holder’s action or inaction impair any such right or
power. If any provision of this Note is found to be invalid by a court, all the other provisions of this Note will remain in full
force and effect. The Company hereby forever waives presentment, protest, notice of dishonor and notice of non-payment. This Note
shall bind the Company and its successors and assigns. The captions contained in this Note are for convenience only, shall not
be deemed to be a part of this Note and shall not be referred to in connection with the construction or interpretation of this
Note. As used in this Note: (a) “or” is not exclusive; (b) “including” and its variants mean “including,
