FOR VALUE RECEIVED, the undersigned, Heart Test Laboratories, Inc. d/b/a HeartSciences, a Texas corporation (“Borrower” or “Company”), hereby promises to pay to the order of __________________, or any future permitted holder of this promissory note (collectively, the “Holder”), at _____________________________, or at such other place as the Holder may designate in writing to the Borrower, the principal sum of _______________Thousand and No/100 Dollars ($________________), and such other amount as may be outstanding hereunder, together with all accrued but unpaid interest, in United States dollars, as provided in this Secured Convertible Promissory Note (the “Note”).

THE PARTIES INTEND THIS INSTRUMENT TO BE EQUITY FOR TAX PURPOSES.

This Note is one of a series (the “Series”) of secured convertible promissory notes (collectively, the “Series Notes”) issued by the Company on the same terms.

1. Principal and Interest Payments.

(a) The principal of this Note shall be due and payable on July 31, 2022 (the “Maturity Date”).

(b) The parties intend this instrument to be equity for tax for purposes and it is expected that the Note shall be converted for equity in the Borrower on or prior to the Maturity Date in which event no interest shall accrue and interest shall not be due or payable.

(c) In the event the Note is not converted on or prior to the Maturity Date then interest shall accrue on the outstanding principal balance of this Note commencing on the date of this Note, at a simple interest a rate of twelve percent (12%) per annum. Interest shall only be payable upon a repayment of the Note in cash by Borrower or upon an Event of Default.

(d) Borrower shall only make interest and principal payments under this Note on a pro rata basis to the Series Notes based on the respective principal amounts of each Note. Each holder of a Note shall hold any amounts received in excess of its pro rata share in trust for the benefit of the other holders of Series Notes.

(e) Borrower shall be entitled to repay the principal and all accrued but unpaid interest on this Note in cash upon giving ten (10) days written notice to the Holder at any time upon or after any of the following events of the Borrower (“Borrower Repayment”):

(i) 30 days following FDA clearance of the Borrower’s MyoVista product;

(ii) the closing of further funding of $5 million or more which values entire share capital of the Borrower at $50 million or more;

(iii) a public offering of Common Stock which values entire share capital of the Borrower at $50 million or more; or

(iv) the sale or merger of a majority of the voting stock of the Borrower.

2. Conversion.

(a) Conversion of this Note shall be into shares of Common Stock of Borrower (the “Common Stock”) at a conversion price of Five Cents ($0.05 US Dollars) per share of Common Stock (“Conversion”) (as adjusted for any splits, recapitalizations, combinations or other similar transactions affecting the Company’s Common Stock).

(b) Borrower may elect for conversion of the principal balance of, and accrued but unpaid interest on, this Note at any time upon or after any of the following events of the Borrower (“Borrower Conversion”):

(i) 30 days following FDA clearance of the Borrower’s MyoVista product;

(ii) the closing of further funding of $5 million or more which values entire share capital of the Borrower at $50 million or more; or

(iii) a public offering of Common Stock which values entire share capital of the Borrower at $50 million or more.

(c) Holder shall be entitled to elect for voluntarily Conversion at any time upon written notice to the Company (“Holder Conversion”). Such election shall be irrevocable and upon receipt of such written notice from the Holder Conversion shall be deemed to have automatically occurred.

As soon as practicable following a Borrower Conversion, Borrower shall send written notice to Holder that such conversion has taken place and that the principal balance of, and accrued but unpaid interest (if applicable under section 1(c)) on, this Note has been converted into shares of Common Stock. Upon Borrower Conversion or Holder Conversion the Borrower shall send written notice to the Holder of the number of shares of Common Stock that Holder is entitled to receive upon such conversion (the “Conversion Shares”). Upon receipt by Borrower from Holder of the original copy of this Note, marked “Canceled”, the Borrower will deliver to Holder a stock certificate evidencing the Conversion Shares. Notwithstanding anything in this Note to the

contrary, effective as of the date that a Borrower Conversion or Holder Conversion, this Note shall be deemed to be canceled in its entirety and the only right of Holder thereafter is to receive from Borrower a stock certificate evidencing the Conversion Shares (which stock certificate shall only be delivered to Holder upon Holder delivering to Borrower the original copy of this Note, marked “Canceled”).

3. Non-Business Days. Whenever any payment to be made shall be due on a Saturday, Sunday or a public holiday under the laws of the State of Texas, such payment may be due on the next succeeding business day and such next succeeding day shall be included in the calculation of the amount of accrued interest payable on such date.

4. Events of Default. The occurrence of any of the following events shall be an “Event of Default” under this Note:

(b) Borrower fails to perform any other covenant contained herein, if the same has continued for thirty (30) days after written notice specifying such default has been delivered to the Borrower by Holder;

(c) Borrower shall (i) apply for or consent to the appointment of, or the taking of possession by, a receiver, custodian, trustee or liquidator of itself or of all or a substantial part of its property or assets, (ii) make a general assignment for the benefit of its creditors, (iii) commence a voluntary case under the Bankruptcy Code or under the comparable laws of any jurisdiction (foreign or domestic), (iv) file a petition seeking to take advantage of any bankruptcy, insolvency, moratorium, reorganization or other similar law affecting the enforcement of creditors’ rights generally, (v) acquiesce in writing to any petition filed against it in an involuntary case under the Bankruptcy Code or under the comparable laws of any jurisdiction (foreign or domestic), or (vi) take any action under the laws of any jurisdiction (foreign or domestic) analogous to any of the foregoing; or

(d) a proceeding or case shall be commenced in respect of Borrower without its application or consent, in any court of competent jurisdiction, seeking (i) the liquidation, reorganization, moratorium, dissolution, winding up, or composition or readjustment of its debts, (ii) the appointment of a trustee, receiver, custodian, liquidator or the like of it or of all or any substantial part of its assets or (iii) similar relief in respect of it under any law providing for the relief of debtors, and such proceeding or case described in clause (i), (ii) or (iii) shall continue undismissed, or unstayed and in effect, for a period of thirty (30) consecutive days or any order for relief shall be entered in an involuntary case under the Bankruptcy Code or under the comparable laws of any jurisdiction (foreign or domestic) against Borrower or any of its subsidiaries or action under the laws of any jurisdiction (foreign or domestic) analogous to any of the foregoing shall be taken with respect to Borrower or any of its subsidiaries and shall continue undismissed, or unstayed and in effect for a period of thirty (30) consecutive days.

Amounts set forth or provided for herein with respect to payments and the like (and the computation thereof) shall be the amounts to be received by Holder and shall not, except as expressly provided herein, be subject to any other obligation of Borrower (or the performance thereof). Borrower acknowledges that a breach by it of its obligations hereunder will cause irreparable and material harm to Holder and that the remedy at law for any such breach may be inadequate. Therefore, Borrower agrees that, in the event of any such breach or threatened breach, Holder shall be entitled, in addition to all other available rights and remedies, at law or in equity, to seek and obtain such equitable relief, including but not limited to an injunction restraining any such breach or threatened breach, without the necessity of showing economic loss and without any bond or other security being required.

IN WITNESS WHEREOF, Borrower has executed and delivered this Note as of the date first written above.
