CONVERSION

at the office of the Company, accompanied by a written notice of conversion in the form of Attachment I hereto, or otherwise in
form reasonably satisfactory to the Company, duly executed by the registered Holder or his, her or its duly authorized attorney.
The aggregate principal amount of this Debenture shall be convertible into shares of Common Stock at a price per share equal to
$0.01 (“Conversion Price”), subject to the adjustments as provided for in Section 2.8(a). The number of shares
issued as payment shall be equal to the quotient of the aggregate outstanding principal on the date of conversion divided by the
Conversion Price.


 


2.2.No
Fractional Shares. Any fractional share resulting from any conversion of the principal or accrued and unpaid interest of this
Debenture shall be rounded up to one whole share.


 


2.3.Transfer
of Debenture; Conversion Procedure. This Debenture is not divisible. This Debenture and all rights hereunder may be sold,
transferred or otherwise assigned to any person in accordance with and subject to the provisions of the Securities Act of 1933,
as amended (the “Securities Act”), and the rules and regulations promulgated thereunder. Upon the transfer

upon surrender thereof for conversion properly endorsed and accompanied by a completed and executed Conversion Notice attached
hereto as Attachment II and any documentation deemed necessary by the Company showing the availability of an exemption under applicable

issue and deliver with all reasonable dispatch to or upon the written order of the Holder of this Debenture and in such name or
names as such Holder may designate, a certificate or certificates for the number of full shares of Common Stock due to such Holder
upon the conversion of this Debenture. The Person or Persons to whom such certificate or certificates are issued by the Company
shall be deemed to have become the holder of record of such shares of Common Stock as of the date of the surrender of this Debenture.

2.4.Issuance
of Shares of Common Stock.


 


(a)Issuance
Upon Conversion. The Company covenants that it will at all times reserve and keep available, free from preemptive rights,
out of its authorized Common Stock, solely for the purpose of issuance upon conversion of this Debenture, such number of shares
of Common Stock as shall equal the aggregate number of shares of Common Stock that would be issued under this Debenture if fully
converted. The Company also covenants that all of the shares of Common Stock that shall be issuable upon conversion of this Debenture
shall, at the time of delivery, be duly and validly issued, fully paid, non-assessable and free from all taxes, liens and charges
with respect to the issue thereof (other than those which the Company shall promptly pay or discharge).


 


(b)Restrictive
Legend. Each certificate evidencing shares of Common Stock issued to the Holder following the conversion of this Debenture,
if any, shall bear the following restrictive legend or a similar legend until such time as the transfer of such security is not
restricted under the federal securities laws:


 


THE
SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”),
OR UNDER ANY STATE SECURITIES LAWS, AND MAY NOT BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED
OF EXCEPT PURSUANT TO (I) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT, (II) TO THE EXTENT APPLICABLE, RULE 144 UNDER THE
ACT (OR ANY SIMILAR RULE UNDER SUCH ACT RELATING TO THE DISPOSITION OF SECURITIES), OR (III) AN OPINION OF COUNSEL, IF SUCH OPINION
SHALL BE REASONABLY SATISFACTORY TO COUNSEL TO THE ISSUER, THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE.


 


2.5.Adjustment
of Conversion Price and Number of Underlying Shares. The number of shares of Common Stock issuable upon the conversion of
this Debenture and the Conversion Price shall be subject to adjustment from time to time as follows:


 


(a)Adjustment
for Stock Splits and Combinations. If the Company at any time or from time to time after the date of this Debenture effects
a subdivision of the outstanding Common Stock or combines the outstanding shares of Common Stock, then, in each such case, the
Conversion Price in effect immediately prior to such event shall be adjusted so that each Holder of conversion rights under this
Debenture shall have the right to convert his, her or its interests into the number of shares of Common Stock which he, she or
it would have owned after the event had such shares of Common Stock been converted immediately prior to the occurrence of such
event. Any adjustment under this Section 2.8(a) shall become effective as of the date and time such subdivision or combination
becomes effective.


 




    	 	3	 



    	 	 	 



    


 


(b)Subsequent
Financing. If at any time subsequent to the issuance of the Debentures and prior to the conversion of the Debentures into
shares of Common Stock, the Company closes on a financing involving the issuance of shares of Common Stock with or at a per share
purchase price that is less than the Conversion Price (the “Subsequent Financing Per Share Price”), then the
Conversion Price shall be reduced to seventy-five percent (75%) of the Subsequent Financing Per Share Price.


 


(c)No
Impairment. The Company will not, through any reorganization, recapitalization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the Company.


 


(d)Record
Date. If the Company takes a record of the holders of Common Stock for the purpose of entitling them (i) to receive a dividend
or other distribution payable in Common Stock, or in any rights, options or warrants to subscribe for or to purchase Common Stock
(such rights or options or warrants being herein called “Options”) or in any stock or other securities convertible
into or exchangeable for Common Stock (such convertible or exchangeable stock or securities being herein called “Convertible
Securities”) or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record
date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon
the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription
or purchase, as the case may be.


 


(e)Actions
to Maintain Conversion Price Above Par Value. Before taking any action which would cause an adjustment in the Maturity Date
Conversion Price such that, upon conversion of this Debenture, shares of Common Stock with par value, if any, would be deemed
to be issued below the then par value of the Common Stock, the Company will take any corporate action which may, in the opinion
of its counsel, be reasonable necessary in order that the Company may validly and legally issue fully paid and non-assessable
shares of Common Stock at the Maturity Date Conversion Price as so adjusted.


 


(f)Certificate
of Adjustment. In any case of an adjustment of the number of shares of Common Stock or other securities issuable upon conversion
of this Debenture, the Chief Financial Officer or the President of the Company shall compute such adjustment in accordance with
the provisions hereof and prepare and sign a certificate showing such adjustment, and shall mail such certificate, by first class
mail, postage prepaid, to the Holder of this Debenture at the Holder’s address as shown in the Company’s books. The
certificate shall set forth such adjustment, showing in detail the facts upon which such adjustment is based, including a statement
of the number of shares of Common Stock and the type and amount, if any, of other property which at the time would be received
upon conversion of this Debenture.


 




    	 	4	 



    	 	 	 



    


 


(g)Closing
of Books. The Company will at no time close its transfer books against the transfer of any shares of Common Stock issued or
issuable upon the conversion of this Debenture in any manner which interferes with the timely conversion of this Debenture into
shares of Common Stock.
