against the THI, and THI’s representatives, officers, shareholders, directors, employees, subsidiaries, affiliates, divisions,
successors and assigns (collectively the “Released Parties”) for infringement of the Miromatrix Patents, and that such

2.2             
Sub-License. THI agrees that the grant of the license by Miromatrix to THI as to Licensed Miromatrix Patents is a sub-license
governed by the terms and subject to the conditions of the License Agreement. Miromatrix agrees that it shall not grant, or consent to
the grant of, any right, title, or license to any Person in or to the Miromatrix Patents if such grant would permit another Person to
make use, sell, offer to sell, supply, or import a Product.


 


2.3            
Research and Development Activities. THI agrees to use reasonable commercial efforts, consistent with sound and reasonable
judgment and practices as customary in the medical device and biological products industries, at its cost and expense, to perform product

collectively, “Miromatrix Milestones”). All fees, costs; and expenses associated with achieving the Miromatrix Milestones
shall be the sole responsibility of Miromatrix; THI shall not be obligated to provide or pay any such fees, costs, or expenses. Failure
by Miromatrix to meet any Miromatrix Milestone in a timely manner shall be grounds for THI exercising its rights to revive its sub-license
as hereinafter set forth.

any part of the Shares. In making these representations, the Subscriber understands that, in the view of the Commission, exemption of

or otherwise dispose of, or agree to sell, transfer or otherwise dispose of any of the Shares beneficially held by the undersigned during
the Lockup Period; (ii) sell, transfer or otherwise dispose of, or agree to sell, transfer or otherwise dispose of any options, rights
or warrants to purchase any of the Shares beneficially held by the undersigned during the Lockup Period; or (iii) sell or grant, or agree

set forth in the paragraph. The term “Lockup Period” means the lesser of (x) 180 days or (y) the shortest period during which
any of the Company’s officers, directors, and shareholders holding 5% or more of the Company’s common stock are restricted

		8.	Stop Transfer Order. The Subscriber agrees that the Company may place
a stop transfer order with its registrar and transfer agent (if any) covering all certificates representing the Shares.



 


		9.	No Public Information. The Subscriber understands and acknowledges
that the Company currently does not file periodic reports with the Commission pursuant to the requirements of Sections 13 or 15(d) of
the Securities Exchange Act of 1934, and may not be obligated to file such reports at any time in the future.



 


		10.	Lack of Availability of Rule 144 Under the Act. The Subscriber understands
and acknowledges that the Company has no obligation to undertake or complete a public offering of its securities, that even if a public
offering is undertaken and successfully completed, the Shares subscribed for hereby will remain subject to the restrictions on transferability
described herein, and that if a public offering is not undertaken and completed, the Subscriber may never be able to sell its Shares pursuant

assumption of any obligation under or in connection with the Collateral. This Agreement does not affect or modify Pledgor’s obligations
with respect to the Collateral.


 


5.       Fraudulent
Conveyance. Notwithstanding anything contained in this Agreement to the contrary, Pledgor agrees that if, but for the application
of this Section 5, the Obligation or any Security Interest would constitute a preferential transfer under 11 U.S.C. §
547, a fraudulent conveyance under 11 U.S.C. § 548 (or any successor section) or a fraudulent conveyance or transfer under any state
fraudulent conveyance or fraudulent transfer Law or similar Law in effect from time to time (each a “Fraudulent Conveyance”),
then the Obligation and each affected Security Interest will be enforceable against Pledgor to the maximum extent possible without causing
the Obligation or any Security Interest to be a Fraudulent Conveyance, and shall be deemed to have been automatically amended to carry
out the intent of this Section 5.


 


6.       Representations
and Warranties. Pledgor hereby represents and warrants to Secured Party as follows:


 


(a)               
Pledgor owns the Collateral free arid clear of all Liens except for the Liens created hereunder.


 


(b)               
The information contained in Schedule 1 attached to this Agreement is true and accurate and sufficiently describes
all of the Collateral.


 


7.       Covenants.
Pledgor shall:


 


(a)               
Promptly notify Secured Party of any material change in any fact or circumstances represented or warranted by Pledgor with respect
to any of the Collateral.


 


(b)               
Promptly notify Secured Party of any claim, action or proceeding materially affecting the security interest granted and the pledge
and assignment made under Section 3 or title to any of the Collateral and, at the request of Secured Party, appear in and defend, at Pledgor’s
expense, any such action or proceeding.


 


(c)               
Not create, incur or suffer to exist any other Lien upon any of the Collateral.


 


(d)               
Not assign, dispose of, sell or otherwise transfer any of the Collateral.


 


(e)               
At Pledgor’s expense and Secured Party’s reasonable request, file or cause to be filed such applications and take such
other actions to obtain the consent or approval of any Governmental Authority to Secured Party’s rights hereunder, including, without
limitation, the right to sell all the Collateral upon a Default without additional consent or approval from such Governmental Authority
(and, because Pledgor agrees that Secured Party’s remedies at law for failure of Pledgor to comply with this provision would be
inadequate and that such failure would not be adequately compensable in damages, Pledgor agrees that his covenants in this provision may
be specifically enforced).


 






    3 


     


    

 


(f)                
 From time to time promptly execute and deliver to Secured Party all such other stock powers, assignments, certificates, supplemental
documents, and financing statements (if appropriate), and do all other acts or things as Secured Party may reasonably request in order
to more fully create, evidence, perfect, continue and preserve the priority of the Security Interest.


 


8.       Default;
Remedies. Should a Default occur and be continuing, Secured Party may, at its election, exercise any and all rights available to a
secured party under the UCC, in addition to any and all other rights afforded by this Agreement, the Note, at law, in equity, or otherwise,
including, without limitation, applying by appropriate judicial proceedings for appointment of a receiver for all or part of the Collateral
(and Pledgor hereby consents to any such appointment).


 


9.       Notice.
Reasonable notification of the time and place of any public sale of the Collateral, or reasonable notification of the time after which
any private sale or other intended disposition of the Collateral is to be made, shall be sent to Pledgor and to any other person entitled
to notice under the UCC; provided that if any of the Collateral threatens to decline speedily in value or is of the type customarily sold
on a recognized market, Secured Party may sell or otherwise dispose of the Collateral without notification, advertisement, or other notice
of any kind. It is agreed that notice sent or given not less than ten calendar days prior to the taking of the action to which the notice
relates is reasonable for the purposes of this Section 9.


 


10.       Sales
of Securities.


 


(g)               
In the event that the Secured Party determines to exercise its right to sell all or any part of the Collateral, Pledgor will, at
Pledgor’s expense and upon request by the Secured Party: (i) execute and deliver, and cause each issuer of such Collateral and the
directors and officers thereof to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts
and things, as may be necessary or, in the opinion of the Secured Party, advisable to register such Collateral under the provisions of
the Securities Act of 1933, as amended (the “Securities Act”), and to cause the registration statement relating
thereto to become effective and to remain effective for such period as prospectuses are required by law to be furnished, and to make all
amendments and supplements thereto and to the related prospectus which, in the opinion of the Secured Party, are necessary or advisable,
all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission
applicable thereto, (ii) cause each issuer of such Collateral to qualify such Collateral under the state securities or “Blue Sky”
laws of each jurisdiction, and to obtain all necessary governmental approvals for the sale of the Collateral, as requested by the Secured
Party, (iii) cause Pledged Issuer to make available to its securityholders, as soon as practicable, an earnings statement which will satisfy
the provisions of Section 11(a) of the Securities Act, and (iv) do or cause to be done all such other acts and things as
may be necessary to make such sale of such Collateral valid and binding and in compliance with applicable law. Pledgor acknowledges the
impossibility of ascertaining the amount of damages which would be suffered by the Secured Party by reason of the failure by Pledgor to
perform any of the covenants contained in this Section 10(a) and, consequently, agrees that, if Pledgor fails to perform
any of such covenants, he shall pay, as liquidated damages and not as a penalty, an amount equal to the value of the Collateral on the
date the Secured Party demands compliance with this Section 10(a); provided that the payment of such amount shall not release Pledgor
from any of its obligations under this Agreement or the Note.


 


(h)                Notwithstanding
the provisions of Section 10(a) hereof, Pledgor recognizes that the Secured Party may deem him impracticable to effect
a public sale of all or any part of the Pledged Equity or any other securities constituting Collateral. Secured Party is authorized,
but not obligated, to limit prospective purchasers to the extent deemed necessary or desirable by Secured Party to render such sale
exempt from the registration requirements of the Securities Act, and any applicable state securities laws, and no sale so made in
good faith by Secured Party shall be deemed not to be “commercially reasonable” because so made. Secured Party may make
one or more private sales of any such securities to a restricted group of purchasers who will be obligated to agree, among other
things, to acquire such securities for their own account, for investment and not with a view to the distribution or resale thereof.
Pledgor acknowledges that any such private sale may be at prices and on terms less favorable to the seller than the prices and other
terms which might have been obtained at a public sale and, notwithstanding the foregoing, agrees that such private sales shall be
deemed to have been made in a commercially reasonable manner and that the Secured Party shall have no obligation to delay the sale
of any such securities for the period of time necessary to permit the issuer of such securities to register such securities for
public sale under the Securities Act. Pledgor further acknowledges and agrees that any offer to sell such securities which has been
(i) publicly advertised on a bona fide basis in a newspaper or other publication of general circulation in the financial community
of Houston, Texas (to the extent that such an offer may be so advertised without prior registration under the Securities Act) or
(ii) made privately in the manner described above to not less than ten (10) bona fide offerees shall be deemed to involve a
 “public disposition” for the purposes of Section 9-610(c) of the UCC, notwithstanding that such sale may not constitute
a “public offering” under the Securities Act, and that the Secured Party may, in such event, bid for the purchase of
such securities.


 






    4 


     


    

 


11.       Application
of Proceeds. Secured Party shall apply the proceeds of any sale or other disposition of the Collateral in the following order: first,
to the payment of all its expenses incurred in retaking, holding and preparing any of the Collateral for sale(s) or other disposition,
in arranging for such sale(s) or other disposition, and in actually selling or disposing of the same (all of which are part of the Obligation);
second, toward repayment of amounts expended by Secured Party under this Agreement; third, toward payment of the balance
of the Obligation in accordance with the Note. Any surplus remaining shall be delivered to Pledgor or as a court of competent jurisdiction
may direct.


 


12.       Other
Rights of Secured Party.


 


(a)               
Performance. In the event Pledgor shall fail to perform any of his obligations hereunder with respect to the Collateral,
then Secured Party may, at its option, but without being required to do so, take such action which Pledgor is required, but has failed
or refused, to take. Any sum which may be expended or paid by Secured Party under this Section 12(a) (including, without
limitation, court costs and reasonable attorneys’ fees) shall bear interest from the dates of expenditure or payment at the default
rate under the Note until paid and, together with such interest, shall be payable by Pledgor upon demand and shall be part of the Obligation.


 


(b)                Collection.
Upon notice from Secured Party, each Person obligated with respect to any of the Collateral, whether as an issuer, account debtor or
otherwise (an “Obligor”) is hereby authorized and directed by Pledgor to make payments on any of the
Collateral (including, without limitation, dividends and other distributions) directly to Secured Party, regardless of whether
Pledgor was previously making collections thereon. Subject to Section 12(e) hereof, until such notice is given,
Pledgor is authorized to retain and expend all payments made on Collateral. Secured Party shall have the right in its own name or in
the name of Pledgor to compromise or extend time of payment with respect to all or any portion of the Collateral for such amounts
and upon such terms as Secured Party may determine; to demand, collect, receive, receipt for, sue for, compound and give
acquittances for any and all amounts due or to become due with respect to Collateral; to take control of cash and other proceeds of
any Collateral; to endorse the name of Pledgor on any notes, acceptances, checks, drafts, money orders or other evidences of payment
on Collateral that may come into the possession of Secured Party; to send requests for verification of obligations to any Obligor;
and to do all other acts and things necessary to carry out the intent of this Agreement. If any Obligor fails or refuses to make
payment on any Collateral when due, Secured Party is authorized, in its sole reasonable discretion, either in its own name or in the
name of Pledgor, to take such action as Secured Party shall deem appropriate for the collection of any such amounts. Regardless of
any other provision hereof, Secured Party shall never be liable for its failure to collect, or for its failure to exercise diligence
in the collection of, any amounts owed with respect to Collateral, nor shall it be under any duty whatever to anyone except Pledgor
to account for funds that it shall actually receive hereunder. Without limiting the generality of the foregoing, Secured Party shall
have no responsibility for ascertaining any maturities, calls, conversions, exchanges, offers, tenders or similar matters relating
to any Collateral, or for informing Pledgor with respect to any of such matters (irrespective of whether Secured Party actually has,
or may be deemed to have, knowledge thereof). The receipt of Secured Party to any Obligor shall be a full and complete release,
discharge and acquittance to such Obligor, to the extent of any amount so paid to Secured Party. The rights granted Secured Party
under this Section 12(b) may be exercised at any time, whether or not a Default has occurred and is continuing.


 






    5 


     


    

 


(c)               
Record Ownership of Securities. When a Default has occurred and is continuing, Secured Party at any time may have the Collateral
registered in its name, or in the name of its nominee or nominees, as pledgee; and Pledgor shall execute and deliver to Secured Party
all such proxies, powers of attorney, dividend coupons or orders and other documents as Secured Party may reasonably request for the purpose
of enabling Secured Party to exercise the voting rights and powers which it is entitled to exercise hereunder and to receive the dividends
and other payments which it is authorized to receive and retain hereunder.


 


(d)               
Voting of Securities. So long as no Default has occurred, Pledgor shall be entitled to exercise all voting rights pertaining
to the Collateral. After the occurrence and during the continuance of a Default, the right to vote the Collateral shall be vested exclusively
in Secured Party. To this end, Pledgor irrevocably appoints Secured Party the proxy and attorney-in-fact of Pledgor, with full power of
substitution, to vote and to act with respect to the Collateral, subject to the understanding that such proxy may not be exercised unless
a Default has occurred and is continuing. The proxy herein granted is coupled with an interest, is irrevocable, and shall continue until
the Obligation has been paid and performed in full.


 


(e)               
Certain Proceeds. Any and all stock or dividends or distributions, or distributions in property made on or in respect of
the Collateral, and any proceeds of the Collateral, whether such dividends, distributions, or proceeds result from a subdivision, combination
or reclassification of the outstanding capital stock or equity owned by Pledgor or as a result of any merger, consolidation, acquisition
or other exchange of assets to which Pledgor may be a party, or otherwise, shall be part of the Collateral hereunder, shall, if received
by Pledgor, be held in trust for the benefit of Secured Party, and shall forthwith be delivered to Secured Party (accompanied by proper
instruments of assignment and/or stock and/or bond powers executed by Pledgor in accordance with Secured Party’s instructions) to
be held subject to the terms hereof. Prior to the occurrence and continuation of a Default, any cash proceeds of Collateral which come
into the possession of Secured Party may, at Secured Party’s option, be applied in whole or in part to the Obligation, or be released
in whole or in part to or on the written instructions of Pledgor for any general or specific purpose not in violation of the Note, or
be retained in whole or in part by Secured Party as additional Collateral. Upon the occurrence and continuation of a Default, any cash
proceeds of Collateral shall be applied to the Obligation.


 






    6 


     


    

 


13.       Miscellaneous.


 


(a)               
Term. Upon full and final payment of the Obligation and final termination of Secured Party’s commitment to lend under
the Note without Secured Party having exercised its rights under this Agreement, this Agreement shall terminate; provided that
no Obligor on any of the Collateral shall be obligated to inquire as to the termination of this Agreement, but shall be fully protected
in making payment directly to Secured Party, which payment shall be promptly paid over to Pledgor after termination of this Agreement.


 


(b)               
Notice. Any notice or communication required or permitted under this Agreement must be given as prescribed in the Note.
Any notice or communication required or permitted to be given to Pledgor hereunder may be given to Pledgor in the manner prescribed in
the Note, and such notice shall constitute notice to Pledgor.


 


(c)               
Governing Law. This Agreement is to be construed, and its performance enforced, under Texas law.


 


(d)               
Note. In the event of any conflict or inconsistency between the terms hereof and the Note, the terms of the Note shall be
controlling.


 


(e)               
Multiple Counterparts and Facsimile Signatures. This Agreement may be executed in any number of counterparts with the same
effect as if all signatories had signed the same document. All counterparts must be construed together to constitute one and the same
instrument. This Agreement may be transmitted and signed by facsimile and portable document format (PDF), and any such facsimile or PDF
signatures shall have the same effect as manually-signed originals and shall be binding on Pledgor and Secured Party.


 


(f)                
Binding Effect; Survival. This Agreement is binding upon, the parties hereto and their respective and successors and permitted
assigns, as applicable.


 


(g)               
Amendments. This Agreement may be amended, modified, supplemented or be the subject of a waiver only by a writing executed
by Secured Party and Pledgor.


 


(h)               
Entirety. THIS AGREEMENT, THE NOTE, AND THE SUBSCRIPTION AGREEMENT REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS
AMONG THE PARTIES.

Chief Executive Officer


 


October 8, 2013


 


Miromatrix Medical Inc. (“Miromatrix”)
and Texas Heart Institute (“THI”) have entered into a Sub-License Agreement dated October 8, 2013, related to research, development,
and commercialization of whole heart products using perfusion based decellularization and recellularization technology licensed to or
owned by Miromatrix (“Agreement”). The Agreement restricts the ability of Miromatrix and THI to assign the Agreement to another
person or entity. Section 10.2 of the Agreement states that consent to an assignment will not be unreasonably withheld.


 


Catholic Health Initiatives (“CHI”)
and THI recently announced a letter of intent for exclusive negotiations toward a new partnership over the next decade for research and
education in cardiovascular diseases. As part of this new partnership, THI and CHI may enter into a joint venture arrangement or form
a new entity with CHI for research and development purposes, including but not limited to research and development of the type of technology
licensed to THI under the Agreement.


 


THI may request a transfer of the Agreement from
THI to the THI/CHI joint venture or new entity, if consummated. Based on discussions between THI and Miromatrix to date, Miromatrix is
not presently aware of any reason to deny such a request. THI will keep Miromatrix seasonably informed of its plans with CHI and any need
in THI’s opinion to assign the Agreement to further the goals of both THI and Miromatrix.


 


Please sign where indicated below to acknowledge
that Miromatrix has been made aware of the potential transfer issue and to acknowledge that the foregoing represents Miromatrix’s
present understanding of the potential transfer request.


 


Sincerely yours,
