	Issue Date:	October 7 2016	:	 Principal Amount: $50,000


 


1. Terms.
For value received, the Regen BioPharma, Inc., a Nevada corporation (the “Company”) hereby absolutely and unconditionally
promises to pay to the order of ________ ON DEMAND any time after October 7, 2018, the principal amount of Fifty Thousand Dollars
($50,000) and interest on the whole amount of said principal sum outstanding and remaining from time to time unpaid (the “Note”),
commencing from the date hereof and continuing until payment in full of this Note or conversion as hereinafter provided, at an
annual rate equal to ten percent (10%) simple interest. Interest shall be payable quarterly upon demand or upon conversion pursuant
to Section 2 hereunder. Interest shall be computed on the basis of the actual number of days elapsed divided by 365. Principal
and interest shall be payable in lawful money of the United States of America, at the principal place of business of the Lender
or at such other place as the Lender may have designated from time to time in writing to the Company.


 


2. Conversion.


 


2.1 Conversion
Right. The Lender shall have the right from time to time to convert all or a part of the outstanding and unpaid principal amount
of this Note into fully paid and non- assessable shares of Common Stock and/or Series A Preferred Stock, as such Common Stock and/or
Series A Preferred Stock exists on the Issue Date, or any shares of capital stock or other securities of the Company into which
such Common Stock and/or Series A Preferred Stock shall hereafter be changed or reclassified at the conversion price (the “Conversion
Price”) determined as provided herein (a “Conversion”). The Lender shall have the right to convert one hundred
percent (100%) of the Principal Amount immediately upon execution of this agreement and any accrued interest may be converted as
well.


 


The number of shares
of Common Stock and/or Series A Preferred Stock to be issued upon each conversion of this Note shall be determined by dividing
the principal amount of this Note to be converted (the “Conversion Amount”) by the applicable Conversion Price as defined
in this Section 2 then in effect on the date specified in the notice of conversion, in the form attached hereto as Exhibit A (the
“Notice of Conversion”), delivered to the Company by the Lender on such conversion date (the “Conversion Date”).


 


2.2 Conversion
Price. The “Conversion Price” shall be defined as $0.0125 per share for either the Common and/or the Series A Preferred
Stock of the Company


 


 


2.3 Method of
Conversion. Subject to Section 2.1, this Note may be converted by the Lender by submitting to the Company a Notice of Conversion
by facsimile, e-mail or other reasonable means of communication dispatched on the Conversion Date prior to 5:00 p.m., New York,
New York time. The Lender shall not be required to physically surrender this Note to the Company unless the entire unpaid principal
amount of this Note is so converted. The Lender and the Company shall maintain records showing the principal amount so converted
and the dates of such conversions so as not to require physical surrender of this Note upon each such conversion. In the event
of any dispute or discrepancy, such records of the Company shall, prima facie, be controlling and determinative in the absence
of manifest error. Notwithstanding the foregoing, if any portion of this Note is converted as aforesaid, the Lender may not transfer
this Note unless the Lender first physically surrenders this Note to the Company, whereupon the Company will forthwith issue and
deliver upon the order of the Lender a new Note of like tenor, registered as the Lender (upon payment by the Lender of any applicable
transfer taxes) may request, representing in the aggregate the remaining unpaid principal amount of this Note.

Upon receipt by
the Company from the Lender of a facsimile transmission, e-mail, or other reasonable means of communication of a Notice of Conversion
meeting the requirements for conversion, the Company shall issue and deliver or cause to be issued and delivered to or upon the
order of the Lender certificates for the Common Stock and/or Series A Preferred Stock issuable upon such conversion within five
(5) business days after such receipt. Upon receipt by the Company of a Notice of Conversion, the Lender shall be deemed to be the
Lender of record of the Common Stock and/or Series A Preferred Stock issuable upon such conversion, the outstanding principal amount
and the amount of accrued and unpaid interest on this Note shall be reduced to reflect such conversion. All rights with respect
to the portion of this Note being so converted shall forthwith terminate except the right to receive the Common Stock and/or Series
A Preferred Stock or other securities as herein provided on such conversion. In lieu of delivering physical certificates representing
the Common Stock and/or Series A Preferred Stock issuable upon conversion, provided the Company is participating in the Depository
Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon request of the Lender,
the Company shall use its best efforts to cause its transfer agent to electronically transmit the Common Stock and/or Series A
Preferred Stock issuable upon conversion to the Lender by crediting the account of Lender’s Prime Broker with DTC through
its Deposit Withdrawal Agent Commission (“DWAC”) system.


 


2.4
Concerning the Shares. The shares of Common Stock and/or Series A Preferred Stock
issuable upon conversion of this Note may not be sold or transferred unless (i) such shares are sold pursuant to an effective registration
statement under the Act or (ii) the Company or its transfer agent shall have been furnished with an opinion of counsel (which opinion
shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the shares
to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or (iii) such shares are sold
or transferred pursuant to Rule 144 under the Act (or a successor rule) ("Rule 144") or (iv) such shares are transferred
to an "affiliate" (as defined in Rule 144) of the Company who agrees to sell or otherwise transfer the shares only in
accordance with this Section 2.5 and who is an Accredited Investor as the term Accredited Investor is defined in Rule 501 of Regulation
D, promulgated under the Act.


 


Subject
to the removal provisions set forth below, until such time as the shares of Common Stock and/or Series A Preferred Stock
issuable upon conversion of this Note have been registered under the Act or otherwise may be sold pursuant to Rule 144 without
any restriction as to the number of securities as of a particular date that can then be immediately sold, each certificate for
shares of issuable upon conversion of this Note that has not been so included in an effective registration statement or that has
not been sold pursuant to an effective registration statement or an exemption that permits removal of the legend, shall bear a
legend substantially in the following form, as appropriate:


 


"NEITHER
THE ISSUANCE OR  SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAS BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I)
IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B)
AN OPINION OF COUNSEL (WHICH COUNSEL SHALL BE SELECTED BY THE LENDER), IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT
REQUIRED UNDER SAID ACT."


 


The
legend set forth above shall be removed and the Company shall issue to the Lender a new certificate therefore free of any transfer
legend if (i) the Company or its transfer agent shall have received an opinion of counsel, in form, substance and scope customary
for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Common Stock and/or
Series A Preferred Stock may be made without registration under the Act and the shares are so sold
or transferred, (ii) such Lender provides the Company or its transfer agent with reasonable assurances that the Common Stock and/or
Series A Preferred Stock issuable upon conversion of this Note (to the extent such securities are
deemed to have been acquired on the same date) can be sold pursuant to Rule 144 or (iii) in the case of the Common Stock
and/or Series A Preferred Stock issuable upon conversion of this Note, such security is registered
for sale by under an effective registration statement filed under the Act or (iv) otherwise may be sold pursuant to Rule 144 without
any restriction as to the number of securities as of a particular date that can then be immediately sold.

Notwithstanding anything to the contrary contained herein, the Company shall have the right, exercisable on not less than three
(3) Trading Days prior written notice to the Lender, to prepay the outstanding Note in part or in full, including outstanding principal
and accrued interest. Any notice of prepayment hereunder shall be delivered to the Lender at its registered addresses and shall
state that the Company is exercising its right to prepay the Note and the date of prepayment, which shall be not more than three
(3) Trading Days from the date of the prepayment notice. Upon receipt of a prepayment notice, Lender shall have the right, but
not the obligation, to accelerate the conversion period specified in Section 2.1 and convert that portion of the outstanding principal

Company to comply in any way with the terms, covenants or conditions contained in this Note.


 


4.2 If an Event
of Default shall occur and be continuing, the Lender may, at its option, declare this Note to be immediately due and payable without
further notice or demand, whereupon this Note shall become immediately due and payable without presentment, demand or protest,
all of which are hereby waived by the Company.


 


5. Transfer of
Note. This Note may not be transferred or assigned other than a transfer or assignment to an Affiliate of the Lender. As used
herein, the term “Affiliate” means an entity that directly, or indirectly through one or more intermediaries, controls,
or is controlled by, or is under common control with, the Lender.


 


6. Certain Waivers.
The Company hereby expressly and irrevocably waives presentment, demand, protest, notice of protest and any other formalities of
any kind.


 


7. Amendment,
Modification or Termination. This Note may only be modified, amended, or terminated (other than by payment in full) by an agreement
in writing signed by the Company and the Lender. No waiver of any term, covenant or provision of this Note shall be effective unless
given in writing by the Lender.
