LICENSE AGREEMENT


 


THIS AGREEMENT is entered
into as of the 15th day of September 2013 (the “Effective Date”), by and between Miromatrix Medical Inc., a corporation organized
under the laws of the State of Delaware and having an office at 18683 Bearpath Trail, Eden Prairie, MN 55347, (“Miromatrix”),
and Mayo Foundation for Medical Education and Research, a not for profit corporation with an address at 200 First Street SW, Rochester,
MN 55905 (“Mayo”).


 


WHEREAS, Miromatrix and Mayo
wish to enter a relationship whereby Mayo performs certain services for Miromatrix relating to Miromatrix decellularization/recellularization
technology (the “Services”);


 


WHERAS, Mayo wishes to acquire
certain Series A Preferred Stock (the “Stock”) from Miromatrix and Miromatrix wishes to provide such Stock to Mayo;


 


WHEREAS, Dr. Allan Dietz of
Mayo’s Human Cellular Therapy Laboratory (the “Laboratory”) shall be Mayo’s principal provider of services for
Miromatrix (the “Principal Investigator”).


 


NOW, THEREFORE, in consideration
of the mutual promises and covenants contained herein, and intending to be legally bound hereby, the parties agree as follows:


 


		1.	Scope of Work.



 


		1.1	Mayo agrees to use its best efforts to perform the Services in accordance with the Statement of Work attached
hereto as Exhibit A (the “Project”).



 


		1.2	Mayo shall perform the Project in accordance with standards applicable to work of similar type and scope
to the Project performed by those skilled in the relevant art, as well as all laws and regulations that apply to such type of work. For
the avoidance of doubt, the work under this agreement will not be to GMP standards.



 


		2.	Term. The parties shall perform their respective obligations for the Project commencing
with the Effective Date of this Agreement and terminating on December 31, 2014 (the “Term”).



 


		3.	Payment.



 


		3.1	The Project will be funded by $200,000.00 (the “Project Cost”) in ILP funds from Mayo, as
