	HTL-CHEN TECHNOLOGY AGREEMENT	  	HIGHLY CONFIDENTIAL















	 	–	 $200 on each MyoVista Device thereafter until total Royalties under this schedule total $3,500,000.



 HTL shall make Royalty payments, on a calendar quarterly basis, in arrears for each immediately preceding calendar quarter, and shall
deliver to Chen, within thirty (30) days of the last day of each such preceding calendar quarter, a report of the number of MyoVista Devices that were Sold (including by Affiliates) during such preceding calendar quarter and the Gross Sale
Price of each MyoVista Device so Sold. 
 Upon reasonable notice at least three (3) business days in advance, Chen (at his cost and expense) shall have
the right, during normal business hours of HTL and no more than twice each calendar year, to audit HTL’s books and records regarding the Royalty payable under this paragraph, which books and records HTL shall keep in accordance with U.S. GAAP,
so that Chen can verify the Royalty paid under this Section 3.1.4. Any underpayment of Royalty bears interest from the date due until the date paid at a 5% annual rate. If the audit reveals an underpayment of $5,000 or more, Chen is entitled to
recover reimbursement of costs incurred for the audit. If the audit reveals an overpayment, Chen shall immediately refund the overpaid amount to HTL. Any successor to HTL, including a buyer of HTL’s assets or stock, or any Third Party acquiring
the business or Covered Technology of HTL shall be bound by this Section and shall assume all Royalty obligations hereunder. Such assumption shall survive any bankruptcy proceeding, and obligate any successor, or subsequent owner of the Intellectual
Property Rights and Covered Technology conveyed to HTL, to HTL’s Royalty payment obligations. In the event of any recovery from litigation arising from unauthorized use of the Intellectual Property Rights or Covered Technology or any other
transferred technology under this Agreement, HTL shall pay to Chen a 2.5% royalty on all net proceeds or the cash equivalent of any non-cash proceeds, assets, or things of value received through settlement of
litigation or negotiation. The payment obligations of HTL under Sections 3.1.1, 3.1.2 and 3.1.4 shall continue regardless of whether any Patent is determined to be invalid or unenforceable of any Intellectual Property Right is determined to be
unenforceable. 
 3.1.5 Agreement Securing Royalty Obligation. The Security Agreement (Exhibit A-3) shall
provide and the Parties expressly agree that without regard to whether any MyoVista Device is Sold, the Royalty obligation hereunder constitutes a secured right to receive aggregate payments in the amount of $3,000,000.00, payment of which is a
material inducement to Chen conveying the Intellectual Property Rights and Covered Technology to HTL. Chen’s right to receive such payments is a secured obligation of HTL in the amount of $3,000,000 with the remaining $500,000 obligation being
unsecured, and a lien shall remain on all secured property unless and until the amount is paid in full or a Final Transfer Event has occurred. In the event of bankruptcy, all Royalty obligations and the obligation to pay Chen an aggregate amount of
$3,500,000 accelerates and becomes a debt obligation of HTL secured by Chen’s lien and due immediately.

 8.1.2 Chen will promptly (and in no case more than ten (10) calendar days after first discovering the
fact of the Loss) give written notice to HTL of any third-party notice, demand or allegation of or relating to any Loss of any type, including an invitation to HTL to participate in the defense. Failure to give such written notice will not relieve
HTL from any liability that HTL may have hereunder. Subject to the proviso that follows, Chen will have the ability to select counsel of its own choosing and will have control over the complete defense, but will not settle without HTL’s
consent, which consent will not be unreasonably withheld; provided, however, that if HTL elects to participate in the defense, if HTL and HTL’s insurer agree to fully indemnify and to pay for all costs of defense and any damages, then Chen may
employ separate counsel at the expense of Chen to assist Chen with respect to any liabilities, claims or suits. Notwithstanding anything else to the contrary, before settling, compromising or otherwise extinguishing any claim by a third-party
(whether or not suit or any other type of dispute resolution procedure has been commenced) made against Chen (a “Settlement”), HTL must first obtain the written consent of Chen, and Chen will have discretion to withhold such consent
if the Settlement (a) is for or involves non-monetary consideration or non-monetary judicial relief, including, but not limited to, promises by Chen to do or forbear from doing any act or the granting of
equitable remedies, (b) involves, requires or implies admissions of wrongful acts (whether civil or criminal) by Chen, (c) would or could impair, invalidate, or result in loss of value of any Intellectual Property or ·rights
thereto, and/or (c) would likely have a detrimental effect on Chen’s reputation or goodwill. 
 8.2 No Limitation on Newly Acquired
Shares. With respect to any shares of HTL newly acquired by Chen after the Effective Date, the Voting Agreement Among Shareholders of Heart Test Laboratories, Inc., dated May 2, 2013, shall have no effect and shall not govern Chen’s
rights in regard to such shares; provided, the voting agreement shall continue in effect as to shares owned by Chen and/or Cheryl Yang on the Effective Date. 

8.3 Right to Designate a Member of the HTL Board of Directors. Until the occurrence of the Final Transfer Event, Chen shall designate a person
of his sole choosing, excluding Robert Eddy, to a seat on the HTL Board of Directors with all the duties, rights, and obligations of the other members. Chen shall provide written notice to HTL, at least ten (10) days prior to such designation,
of Chen’s desired designee for the seat on the HTL Board of Directors. Chen’s designee to the HTL Board of Directors may refer information of Board proceedings and actions to Chen.

 ARTICLE X 

Confidentiality 
 Each
Party (a “Disclosing Party”), at its discretion, may on or after the Effective Date disclose to the other Party (a “Receiving Party”) certain of the Disclosing Party’s Confidential Information. In consideration
of each and every disclosure of Confidential Information by the Disclosing Party to the Receiving Party, the Receiving Party agrees (i) to treat as confidential and to preserve the confidentiality of all Confidential Information disclosed by the
Disclosing Party to the Receiving Party, (ii) to use any and all Confidential Information solely for purpose of this Agreement and for no other purpose, (iii) to make no disclosure of any Confidential Information to any Third Party,
(iv) to limit access to Confidential Information to those officers and employees of the Receiving Party having a need to know such information for purposes of this Agreement and who are bound by a written obligation to maintain confidential and
not use or disclose such Confidential Information, which written obligation is at least as restrictive as the terms of this Article X, and (v) to maintain in confidence any information regarding the nature or scope of any transaction or
relationship between the Disclosing Party and the Receiving Party, except to the extent such information must be disclosed pursuant to law or is disclosed to the Party’s attorneys or accountants, and then only after notifying the Disclosing
Party of such requirement. Any obligation imposed by this Article X may be waived only in writing signed by authorized representatives of the Disclosing Party and the Receiving Party, and only as to the particular Confidential Information and to a
particular use or disclosure stated in the writing. Any such waiver will have a one-time effect and will not apply to any subsequent situation regardless of its similarity. All Confidential Information will
remain the property of the Disclosing Party. Upon request of the Disclosing Party or termination of this Agreement, the Receiving Party will promptly return to the Disclosing Party all Confidential Information of the Disclosing Party, and each and
every part, reproduction and copy of any thereof and each and every narrative, synopsis, summary, note, writing and media containing, embodying, evidencing or describing any part. This Article X and the obligations hereunder, shall survive
termination of the Agreement to the later of: (a) ten (10) years from the date of termination of the Agreement, or (b) the date on which any trade secret embodied or knowable from the Confidential Information shall no longer remain a trade
secret. For purposes of this Article X, the Technical Information is deemed Confidential Information of the owner of the Technical Information. 

ARTICLE XI 

Miscellaneous 
 11.1 Costs. Except as
otherwise expressly provided herein, each Party will bear all of its own costs relating to this Agreement, including, by way of example and not by way of limitation, the cost of negotiating and entering into this Agreement and the cost of fulfilling
all of its obligations under this Agreement. 
 11.2 Injunction; Specific Performance; Remedies. Each Party hereby agrees that, in the event of any breach
by the Party of any of Article II or X, or Sections 6.2.2, 6.2.3, or 6.3.1 or any other breach where such breach may cause irreparable harm to the other Party or where monetary damages may not be sufficient or may not be adequately quantified or
effected, such other Party is entitled to obtain temporary and permanent injunctive relief, without posting bond. Each Party shall have remedy of specific performance to enforce this Agreement, in addition to such other remedies that the Party may
have at law or in equity. Except as otherwise provided in this Agreement, all remedies are cumulative and non-exclusive of any other remedy a Party may have at law or in equity.

 11.3 Severability. If any provision of this Agreement is found· by a court of competent jurisdiction
to be invalid, illegal, unenforceable or in conflict with any controlling law: (a) such provision will be separated from this Agreement; (b) such invalidity, illegality, unenforceability or conflict will not affect any other provision
hereof; and (c) this Agreement will be interpreted and construed as if such provision, to the extent the same will have been held invalid, illegal, unenforceable or in conflict had never been contained herein. In the event the legality of any
provision of this Agreement is brought into question because of a decision by a court or other tribunal of competent jurisdiction of any country in which this Agreement applies, the Parties may agree to revise the provision in question or may delete
it entirely so as to comply with the decision of the court or other tribunal and so as to most closely comply with the intent of this Agreement prior to the revision or deletion of the provision in question. 

11.4 Waiver. No waiver hereunder may be effective unless specifically made in a writing signed by the waiving Party and specifically describing the waived
breach or term or provision. A waiver of any breach or term or provision of this Agreement by either Party shall not be or constitute a waiver of any other or subsequent breach, term or provision, nor shall any such waiver affect the rights of the
waiving Party to demand strict compliance with the terms hereof. 
 11.5 Amendment. Any modification or amendment of this Agreement will be effective only
if made in writing and signed by both Parties. 
 11.6 Relationship of the Parties. Each Party is an independent contractor of the other Party. Under no
circumstances will any employees of one Party be deemed the employees of the other Party for any purpose. This Agreement does not create a partnership, joint venture or agency relationship between the Parties of any kind or nature. This Agreement
does not create any fiduciary or other obligation between the Parties, except for those obligations expressly and specifically set forth herein. Neither Party will have any right, power, or authority under this Agreement to act as a legal
representative of the other Party, and neither Party will have any power to obligate or bind the other Party or to make any representations, express or implied, on behalf of or in the name of the other Party in any manner or for any purpose
whatsoever. 
 11.7 Governing Law; Venue for Suit; Jurisdiction of Court. This Agreement and the rights and obligations of the Parties hereunder will be
governed by and construed and interpreted in accordance with the laws of the State of Texas, without regard to choice or conflict of laws principles, applicable to agreements made and to be performed entirely within such state. Each Party
irrevocably submits and unconditionally waives any objection to the jurisdiction and venue of the federal or state courts in the State of Texas for purpose of any suit, action or other proceeding arising out of this Agreement or any transaction
contemplated hereby, and each Party hereby further waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. Each Party agrees to provide
counsel for the other Party notice, in the manner provided in Section 11.10, of any lawsuit filed under or in connection with this Agreement.

 or to such other address as a Party may hereafter designate to the other in writing pursuant to this
Section 11.11. A notice under this Agreement will be effective on the date of personal delivery or three (3) days after deposit in the U.S. mail. 

11.11 Construction. All of the terms and conditions of this Agreement are the result of arms-length negotiation among the Parties, each of which
has had opportunity and has obtained the advice of legal counsel. Any principle of contract interpretation construing a contract or provision against the drafter will not apply to this Agreement or any provision, it being agreed that the Parties
have equally participated in the preparation and negotiation hereof and of all provisions. 
 11.12 Assignment; Successors and Assigns. Except
as provided in this Section 11.12, or as otherwise provided in this Agreement (which assignment shall require the assumption of all of HTL’s obligations hereunder), a Party shall not assign this Agreement or any right or interest under
this Agreement, nor delegate any work or obligation to be performed under this Agreement (an “assignment”), without the other Party’s prior written consent, which consent shall not be unreasonably withheld; provided, (i) HTL and
its Affiliates may at any time assign this Agreement in its entirety (but not otherwise) to any person who succeeds to a controlling equity interest of HTL by sale, merger, or reorganization or who purchases
substantially-all of the assets of HTL which are subject of this Agreement, but only if such successor or purchaser is a publicly traded company having a market capitalization of at least $50,000,000.00, or
tangible assets exceeding liabilities of at least $10,000,000.00 and assumes the obligations of its assignor hereunder; (ii) subject to Chen’s first lien rights, which shall be affirmatively disclosed to any financial institution, and such
first lien rights shall be maintained, HTL and its Affiliates may pledge or collaterally assign any or all of its rights under this Agreement to any financial institution; (iii) HTL and its Affiliates may at any time transfer rights to use the
Covered Technology to Customers or to Consultants to HTL involved in research, development, testing or marketing of MyoVista; and (iv) a Party may assign or otherwise transfer any right or obligation of this Agreement to an Affiliate of the
Party, provided the Party shall remain liable for all its responsibilities and obligations under this Agreement and shall be and remain liable for the conduct and performance of each such assignee or transferee and such Affiliate assumes the
obligations of the assigning Party under this Agreement (each a “Permitted Assign”). Subject to the foregoing of this Section 11.12 and the other terms of this Agreement, this Agreement will be binding upon and inure to the
benefit of the Parties and their respective heirs, successors and assigns. 
 11.13 Force Majeure. Neither Party will be liable for any
failure or delay in performing its obligations hereunder due to any external cause beyond its reasonable control, including, by way of example and not by way of limitation, fire, accident, acts of the public enemy, war, riot, rebellion, labor
dispute, strike, lock-out, labor shortage, labor unrest, insurrection, sabotage, epidemic, transportation delay, shortage of raw materials, supplies, energy, components or machinery, an act of God or
government or the judiciary, or any other cause beyond the reasonable control of the non-performing or late-performing Party. Notwithstanding the foregoing, nothing in this section excuses a failure or delay
to perform payment or other monetary obligations.

 11.14 Further Acts. Each Party will, at any time and from time to time during and after the
Term of this Agreement upon the request of the other Party, take all such further actions and execute and deliver all such further instruments, papers or documents, as may be necessary or appropriate to consummate and implement fully the
transactions contemplated herein, and otherwise to effectuate the stated purposes and intents of this Agreement. 
 11.15 Counterparts; Facsimiles
and Scans. This Agreement and exhibits thereto may be executed in one or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. Facsimiles and electronic scans
containing original signatures will be deemed for all purposes to be originally-signed copies of the documents which are the subject of such facsimiles or scans. 

11.16 Attorneys’ Fees. In any action or proceeding between the Parties hereunder, the prevailing Party will be entitled to recover all
fees, costs and other expenses (including, without limitation, the reasonable expenses of its attorneys) incurred in addition to any other relief to which it may be entitled.
