attorney. The aggregate principal amount of this Debenture shall be convertible into shares of Common Stock at a price per share
equal to $0.07 (“Conversion Price”), subject to the adjustments as provided for in Section 2.8(a). The number of shares

Conversion Price. Interest shall accrue to and include the day prior to the date of conversion and shall be paid by check or in
shares of Common Stock, pursuant to Section 2.4, on the last day of the month in which conversion rights hereunder are exercised.


 


2.2.

at the option of the Company, the principal of this Debenture, in whole or in part, shall be converted into shares of Common Stock
at the Conversion Price, subject to the adjustments provided 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. Interest
shall accrue to and include the day prior to the date of conversion and shall be paid by check or in shares of Common Stock, pursuant
to Section 2.4, on the last day of the month in which conversion rights hereunder are exercised.


 


A

immediately prior to such consolidation, merger, sale of all or substantially all of the Company’s assets or other transaction

Upon conversion, the Holder will be required to execute and deliver any documentation deemed necessary by the Company showing
the availability of an exemption under applicable state and federal securities laws.


 


2.7.
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)

restricted under the federal securities laws:

SHALL BE REASONABLY SATISFACTORY TO COUNSEL TO THE ISSUER, THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE.


 




    	 	 3	 



     

    

 


2.8.
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.


 


(b)
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.


 


(c)
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.


 


(d)
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.


 


(e)
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.


 


(f)
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.
