AGREEMENT


 


THIS RESTRICTED STOCK
PURCHASE AGREEMENT (the “Agreement”) is entered into as of June 16, 2012 by and between _______________,
(hereinafter referred to as “Purchaser”) and Medistem Inc., a Nevada corporation (hereinafter referred to as the “Company”).


 


RECITALS:


 


A.                
Purchaser is an employee, director, or other service provider of the Company, and in connection therewith has
rendered and continues to render services for and on behalf of the Company.


 


B.                
The Company desires to issue shares of common stock to Purchaser for the consideration set forth herein to provide
an incentive for Purchaser to exert added effort towards its growth and success.


 


NOW, THEREFORE, in
consideration of the mutual covenants hereinafter set forth, and for other good and valuable consideration, the parties agree as
follows:


 


1.                 
Issuance of Shares. The Company hereby agrees to issue to Purchaser, and Purchaser hereby agrees
to acquire, _______________ shares of Common Stock of the Company (the “Shares”) on the terms and conditions
herein set forth.


 


2.                 
Consideration. The purchase price for the Shares shall be $0.0001 per share, or $__________, which
shall be paid by the delivery of Purchaser’s check payable to the Company contemporaneous with the execution and delivery
of this Agreement.


 


3.                 
Vesting of Shares. Shares which have not yet become vested are herein called “Unvested Shares.”
The Shares acquired hereunder are in the first instance Unvested Shares, but they shall (if they have not previously been repurchased
pursuant to Section 5) vest and become “Vested Shares” (and such Unvested Shares shall thereafter not be subject to
the repurchase obligation provided for in Section 5), immediately upon the earliest of:


 


(a)              
June 16, 2017; or


 


(b)              
the closing of an underwritten public offering of shares of the Company’s Common Stock for gross proceeds
of at least $20,000,000 pursuant to a registration statement filed with and declared effective by the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the “Securities Act”); or


 


(c)               
the occurrence of a Change in Control. “Change of Control” means (1) a sale of all or substantially
all of the Company’s assets to an unaffiliated person or entity, (2) any merger, consolidation or other business combination
transaction of the Company with or into an unaffiliated person or entity, other than a transaction in which the holders of at least
a majority of the shares of voting capital stock of the Company outstanding immediately before such transaction continue to hold
(either by such shares remaining outstanding or by their being converted into shares of voting capital stock of the surviving entity)
a majority of the total voting power represented by the shares of voting capital stock of the Company (or the surviving entity)
outstanding immediately after such transaction, (3) the direct or indirect acquisition (including by way of a tender or exchange
offer, but excluding any bona fide capital-raising transaction) by any person, or persons acting as a group, of beneficial ownership
or a right to acquire beneficial ownership of shares representing a majority of the voting power of the then outstanding shares
of capital stock of the Company, or (4) a contested election of Directors, as a result of which or in connection with which the
persons who were Directors before such election or their nominees (the “Incumbent Directors”) cease to constitute a
majority of the Board; provided however that if the nomination for election by the Company’s stockholders of any new Director
was approved by a vote of at least 50% of the Incumbent Directors, such new Director shall be considered as an Incumbent Director.


 






    	 



    	 



    

 


4.                 
Deposit of Unvested Shares. Purchaser shall deposit with the Company certificates representing
the Unvested Shares, together with a duly executed stock assignment separate from certificate in blank, which shall be held by
the Secretary of the Company. Purchaser shall be entitled to vote all such deposited Unvested Shares and to receive dividends and
distributions on all such deposited Unvested Shares. When and if the Shares become Vested Shares, such certificates shall be released
to Purchaser.


 


5.                 
Company’s Right to Repurchase Unvested Shares.


 


(a)              
Repurchase Requirement. On May 2, 2015, in the event that for any reason the Company has not raised from
unaffiliated persons, between the date of this Agreement and May 1, 2015, gross proceeds of at least $1,200,000 from the sale of
stock (but not including sales of convertible notes or conversions of convertible notes), then the Company may repurchase, and
Purchaser shall be obligated to sell to the Company, as provided in this Section 5, any and all Shares which on May 2, 2015 are
Unvested Shares, at a repurchase price of $0.0001 per Unvested Share.


 


(b)              
Settlement. For such repurchase, Purchaser (or other applicable holder) shall deliver to the Company certificate(s)
representing the Unvested Shares to be acquired by the Company, duly endorsed for surrender, on May 2, 2015. (Or if such certificate(s)
and associated stock powers have been deposited and lodged with the Company, the Company shall remove such certificate(s) and associated
stock powers from lodgment and deem them to be delivered to the Company for such repurchase.) The Company shall deliver to Purchaser
against delivery of the Unvested Shares, checks of the Company payable to Purchaser and/or any other person obligated to transfer
the Unvested Shares in the aggregate amount of the repurchase price to be paid as set forth in Section 5(a) above.


 


(c)               
Legend. The stock certificates for the Shares purchased pursuant to this Agreement shall be endorsed with
the following legend:


 


THE SHARES REPRESENTED BY THIS CERTIFICATE
MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED OR ENCUMBERED, EXCEPT IN CONFORMITY WITH THE TERMS OF A RESTRICTED STOCK PURCHASE
AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER OF THE SHARES (OR ITS PREDECESSOR IN INTEREST). THE SHARES REPRESENTED
BY THIS CERTIFICATE ARE, UNTIL THEY HAVE VESTED, POTENTIALLY SUBJECT TO MANDATORY REPUIRCHASE BY THE COMPANY FOR A NOMINAL PRICE
PURSUANT TO THE TERMS OF SUCH AGREEMENT. A COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

6.                 
Adjustments upon Changes in Capital Structure. In the event that the outstanding Shares of Common
Stock of the Company are hereafter increased or decreased or changed into or exchanged for a different number or kind of shares
or other securities of the Company by reason of a recapitalization, stock split, combination of shares, reclassification, stock
dividend, or other change in the capital structure of the Company, then Purchaser shall be entitled to new or additional or different
shares of stock or securities, in order to preserve, as nearly as practical, but not to increase, the benefits of Purchaser under
this Agreement. Such new, additional or different shares shall be deemed “Shares” for purposes of this Agreement and
subject to all of the terms and conditions hereof.


 


7.                 
Shares Free and Clear. All Unvested Shares repurchased by the Company pursuant to this Agreement
shall be delivered by Purchaser free and clear of all claims, liens and encumbrances of every nature (except the provisions of
this Agreement and any conditions concerning the Shares relating to compliance with applicable federal or state securities laws),
and the Company shall acquire full and complete title and right to all of the shares, free and clear of any claims, liens and encumbrances
of every nature (again except for the provisions of this Agreement and such securities laws).


 


8.                 
Investment Representations. Purchaser acknowledges that he is aware that the Shares to be issued
to him by the Company pursuant to this Agreement have not been registered under the Securities Act. In this connection, Purchaser
warrants and represents to the Company as follows:


 


(a)              
Purchaser is purchasing the Shares solely for Purchaser’s own account for investment and not with a view
to or for sale or distribution of the Shares or any portion thereof and not with any present intention of selling, offering to
sell or otherwise disposing of or distributing the Shares or any portion thereof. Purchaser also represents that the entire legal
and beneficial interest of the Shares Purchaser is purchasing is being purchased for, and will be held for the account of, Purchaser
only and neither in whole nor in part for any other person.


 


(b)              
Purchaser has heretofore discussed the Company and its plans, operations and financial condition with its officers
and that Purchaser has heretofore received all such information as Purchaser deems necessary and appropriate to enable Purchaser
to evaluate the financial risk inherent in making an investment in the Shares of the Company and Purchaser further represents and
warrants that Purchaser has received satisfactory and complete information concerning the business and financial condition of the
Company in response to all inquiries in respect thereof.


 


(c)               
Purchaser realizes that the purchase of the Shares is a highly speculative investment and represents that Purchaser
is able, without impairing Purchaser’s financial condition, to hold the Shares for an indefinite period of time and to suffer
a complete loss on the investment.


 


(d)              
The Company hereby discloses to Purchaser and Purchaser hereby acknowledges that:


 


(i)                
the Shares have not been registered under the Securities Act, and such Shares must be held indefinitely unless
a transfer of them is subsequently registered under the Securities Act or an exemption from such registration is available;


 


(ii)              
the share certificate representing the Shares will be stamped with the legends restricting transfer specified
in this Agreement between the Company and Purchaser; and


 






    	3



    	 



    

 


(iii)            
the Company will make a notation in its records of the aforementioned restrictions on transfer and legends.


 


(e)               
Purchaser understands that the Shares are restricted securities within the meaning of Rule 144 promulgated
under the Securities Act; that the exemption from registration under Rule 144 will not be available in any event for at least
one (1) year from the date of sale of the Shares to Purchaser, and even then will not be available unless (i) a public
trading market then exists for the Shares of the Company, (ii) adequate current public information concerning the Company
is then available to the public, (iii) Purchaser has been the beneficial owner and Purchaser has paid the full purchase price
for the Shares at least one (1) year before the sale, and (iv) other terms and conditions of Rule 144 are complied
with; and that any sale of the Shares may be made by it only in limited amounts in accordance with such terms and conditions, as
amended from time to time.


 


(f)                
Without in any way limiting any of the other provisions of this Agreement or its representations set forth above,
Purchaser further agrees that Purchaser shall in no event make any disposition of all or any portion of the Shares which Purchaser
is purchasing unless and until:


 


(i)                
there is then in effect a Registration Statement under the Securities Act covering such proposed disposition
and such disposition is made in accordance with said Registration Statement; or


 


(ii)              
(A) Purchaser shall have notified the Company of the proposed disposition
and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, (B) Purchaser
shall have furnished the Company with an opinion of counsel (or any other demonstration which the Company, in its sole and absolute
discretion, chooses to accept in lieu of an opinion of counsel) to the effect that such disposition will not require registration
of such shares under the Securities Act, and (C) such opinion of counsel (if any) shall have been concurred in by counsel
for the Company and the Company shall have advised Purchaser of such concurrence.


 


9.                 
Unpermitted Transfers. The Shares may not be sold, assigned, transferred, pledged or encumbered,
except in conformity with the terms of this Agreement. The Unvested Shares may not be sold, assigned, transferred, pledged or encumbered,
except Purchaser may transfer all or any portion of the Unvested Shares to a trust established for the sole benefit of Purchaser
and/or his spouse or children, provided that the Unvested Shares so transferred shall remain subject to the terms and conditions
of this Agreement and no further sale, assignment, transfer, pledge or encumbrance of such Shares may be made so long as they are
Unvested Shares. The Company shall not be required to: (i) transfer on its books any Shares which shall have been sold or
transferred in violation of any of the provisions set forth in this Agreement, or (ii) treat as owner of such Shares or to
accord the right to vote as such owner or to pay dividends to any transferee to whom such Shares shall have been so transferred.


 


10.             
Notices. Any notice, demand or request required or permitted to be given under this Agreement shall
be in writing and shall be deemed given when delivered personally or three days after being deposited in the United States mail,
as certified or registered mail, with postage prepaid, (or by such other method as the Company may from time to time deem appropriate),
and addressed, if to the Company, at its principal place of business, Attention: the Chief Financial Officer, and if to Purchaser,
at his most recent address as shown in the employment or stock records of the Company.

either express or implied, with respect thereto.


 


15.             
Assignment. Purchaser shall have no right, without the prior written consent of the Company, to
(i) sell, assign, mortgage, pledge or otherwise transfer any interest or right created hereby, or (ii) delegate his duties
or obligations under this Agreement. This Agreement is made solely for the benefit of the parties hereto, and no other person,
company, partnership, association or corporation shall acquire or have any right under or by virtue of this Agreement.

No Agreement to Employ or Engage. Nothing in this Agreement shall obligate the Company or its Affiliates,
or their respective stockholders, Board of Directors, officers or employees to continue any relationship that Purchaser might have
as a director, consultant or employee of the Company. All legal rights of the Company or any of its subsidiaries to terminate at
will Purchaser’s employment or other service at any time (whether by dismissal, discharge or otherwise), with or without

exceed 180 days) from the effective date of such registration as the Company or the underwriters may specify.

Tax Elections. Purchaser understands that Purchaser (and not the Company) shall be responsible
for Purchaser’s own tax liability that may arise as a result of the acquisition of the Shares. Purchaser acknowledges that
Purchaser has considered the advisability of all tax elections in connection with the purchase of the Shares, including the making
of an election under Section 83(b) under the Internal Revenue Code of 1986, as amended (“Code”); Purchaser further
acknowledges that the Company has no responsibility for the making of such Section 83(b) election. In the event Purchaser
determines to make a Section 83(b) election, Purchaser agrees to timely provide a copy of the election to the Company as required
under the Code.
