Item 1.01 Entry into a Material Definitive

Agreement.

On June 23, 2026, CERo Therapeutics Holdings,

Inc., a Delaware corporation (the “Company”) entered into an amended and restated promissory note (the “Note”) with

SRX Health Solutions, Inc. (“Lender”), which amends and restates in its entirety that certain promissory note issued by the

Company in favor of the Lender on May 28, 2026 (the “Original Note”). Pursuant to the Note, the Company may borrow, from time

to time thereunder, up to a maximum aggregate amount not to exceed a sum of $1,413,600 (the “Maximum Loan Amount”). Of the Maximum

Loan Amount, $750,000 was funded pursuant to the Original Note, and an additional $663,600 was funded on June 23, 2026. The Note bears

interest at a rate of 10% per annum, matures on May 28, 2027, and is convertible into shares of the Company’s common stock, par

value $0.0001 per share (the “Common Stock”). At any time after the issuance of the Note, the Lender, at its option, is entitled

to convert all or any lesser portion of the outstanding principal amount and accrued but unpaid interest into Common Stock at a conversion

price equal to the lesser of (i) $0.05 and (ii) 80% of the average of the 5 (five) lowest intraday trading prices during the 20 (twenty)

days prior to the day that the Lender requests conversion, unless otherwise modified by mutual agreement between the parties, subject

to certain adjustments and limitations, including a beneficial ownership limitation of 4.99%.

Pursuant to the terms of the Note, the Company

shall prepare and file with the U.S. Securities and Exchange Commission (the “SEC”), a registration statement on Form S-1

or S-3, covering the resale of all of the shares of Common Stock issuable upon the conversion of the Note.

The issuance of the Note was made in reliance

upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”),

and Rule 506(b) promulgated thereunder. The Note and the shares of Common Stock issuable upon conversion thereof have not been registered

under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration

requirements.

The foregoing description of the Note is qualified

in its entirety by reference to the full text of such document, a copy of which is filed as Exhibit 4.1 to this Current Report on Form

8-K and is incorporated herein by reference.

Item 2.03 Creation of a Direct Financial Obligation

or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information set forth under Item 1.01 of this

Current Report on Form 8-K is incorporated by reference into this Item 2.03.

Item 3.02 Unregistered Sales of Equity Securities.

The information set forth under Item 1.01 of this

Current Report on Form 8-K is incorporated by reference into this Item 3.02. The issuance of the Note was made in reliance on the exemption

provided by Section 4(a)(2) of the Securities Act, for the offer and sale of securities not involving a public offering. The Company’s

reliance upon Section 4(a)(2) of the Securities Act in issuing the Notes was based upon the following factors: (a) the issuance of the

Note was an isolated private transaction by us which did not involve a public offering; (b) the Lender is an accredited investor;

(c) the Company did not engage in general solicitation or advertising in connection with the issuance; and (d) the Lender represented

that, among other things, it was acquiring the securities for investment purposes only and not with a view to distribution, it has received

information about the Company necessary to make an informed investment decision, and the Lender is capable of evaluating the merits and

risks of its investment. Any shares of Common Stock issuable upon conversion of the Note will be issued in reliance on the exemption from

registration provided by Section 3(a)(9) or Section 4(a)(2) of the Securities Act.

AMENDED

AND RESTATED CONVERTIBLE GRID PROMISSORY NOTE

Up to a Principal Amount of $1,767,000.00 with 25% OID

for a Tranche Funding of up to $1,413,600.00

Original Issued Date: May 28, 2026

Maturity Date: May 28, 2027

FOR VALUE RECEIVED, on demand as permitted herein,

CERo Therapeutics Holdings, Inc. (the “Borrower”) or the (“Company”), whose business

address is 201 Haskins Way, Suite 230, South San Francisco, CA 94080, promises to pay to the order of SRX Health Solutions, Inc. (the

“Lender”), at its offices 801 US Highway 1, North Palm Beach, Florida, 33408 or at such other place as the Lender

may designate in writing, the principal sum of the amount of loans (the “Loans”) outstanding hereunder, as conclusively

evidenced on the grid attached hereto as Schedule I. This Note amends and restates in its entirety that certain Convertible Grid Promissory

Note issued by Borrower in favor of the Lender dated May 28, 2026 (the “Original Note”).

1. Conclusiveness of Grid. The Loan represented by this Note is such that, during the term, the Lender

shall advance to the Borrower, from time to time hereunder, a Loan, up to an aggregate amount not to exceed the sum of $1,413,600 (One

Million Four Hundred Thirteen Thousand Six Hundred Dollars) (the “Maximum Loan Amount”), $750,000.00 of which

was funded pursuant to the Original Note and the remainder of which ($663,600.00) will be funded on the date hereof (the “Funding

Date”). The Grid shall, in the absence of manifest error, constitute conclusive proof of the amounts and dates of all advances

and repayment of principal in respect to the Loan.

2. Advances; Schedule I. The Lender will advance the amount of $663,600.00 to the Borrower on the

Funding Date, which amount shall be used by Borrower as set forth on Schedule II to Note. Upon delivery of any tranche amount under

this Note to the Borrower, the Lender is hereby authorized by Borrower to enter and record on Schedule I attached hereto the amount

of the Loan made under this Note and each payment of principal thereon without any further action on the part of Borrower or any endorser

or guarantor of this Note. To the extent interest is not paid when due, the Lender is authorized and directed to enter the amount of such

interest as a Loan on Schedule I. The entry of a Loan on said schedule shall be prima facie and presumptive evidence of the entered

Loan and its conditions. The Lender’s failure to make an entry, however, shall not limit or otherwise affect the obligations of the Lender

to advance the principal amount of the Loan or of the Borrower or any endorser or guarantor of this Note with respect to the Loan.

3. Interest. The principal balance of this Note outstanding from time to time as reflected on Schedule

I shall bear interest at a rate of 10% per annum. The interest shall be calculated on the basis of a three hundred sixty-five (365) day

year for the actual number of days elapsed on the outstanding balance. Interest shall accrue and shall be payable on the Maturity Date

in cash, check or wire transfer in currency of the United States of America at the time of payment that shall be legal tender for the

payment of debt, or Lender may elect to take such interest in common stock of the Borrower, par value $.001 per share (the “Common

Stock”) consistent with Section 5 below. Nothing herein shall be construed to operate as to require Borrower to pay interest at

a greater rate than is now lawful. Should any interest or other charges paid by Borrower result in a payment in excess of the maximum

rate of interest that is legally permitted under applicable law, then all such excess paid by Borrower shall be automatically credited

against and in reduction of the balance due under the Loan or at the option of the Borrower, be refunded. If this Note has already been

repaid in full, then an additional interest amount will be computed in accordance with the preceding sentence and immediately paid by

Borrower along with interest on the amount of such additional interest through the date of payment at a rate per annum equal to the then

existing interest rate on this Note.

4. Waiver. The Borrower hereby waives presentment, demand, notice, protest, and all other demands

and notices in connection with the delivery, acceptance, performance and enforcement of this Note, and assent to extensions of the time

of payment or forbearance or other indulgence without notice. No delay or omission of Lender in exercising any right or remedy hereunder

shall constitute a waiver of any such right or remedy. Acceptance by Lender of any payment after demand shall not be deemed a waiver of

such demand. A waiver on one occasion shall not operate as a bar to or waiver of any such right or remedy on any future occasion.

5. Conversion. Subject to the Ownership Limitation (as defined below) the Lender is entitled, at its

option, at any time after the issuance of this Note, to convert all or any lesser portion of the outstanding principal amount and accrued

but unpaid interest into Common Stock at a conversion price for each share of Common Stock equal to the lesser of (i) $0.05 (the “Floor

Price”) and (ii) 80% of the average of the five (5) lowest intraday trading prices during the twenty (20) days prior to

the day that the Lender requests conversion, unless otherwise modified by mutual agreement between the Parties (the “Conversion

Price”). The shares of Common Stock into which the Note is converted shall be referred to in this agreement as conversion

shares (“Conversion Shares”); provided that if the Conversion Price, as calculated above, is below the Floor

Price, the Lender hereby agrees to use the Floor Price as the Conversion Price. Notwithstanding the foregoing, if the Conversion Price

is lower than the Floor Price at the time the Conversion Shares are actually issued, then the Borrower shall issue a cash payment, in

readily available funds to Lender equal to the product of (i) (x) the number of Conversion Shares issuable upon conversion of the portion

of the Note converted, assuming a Conversion Price equal to the price determined by clause (ii) of the preceding sentence (the “Assumed

Conversion Price”) minus (y) the number of Conversion Shares actually issued upon conversion of such portion of the Note

at the Floor Price multiplied by (ii) the Assumed Conversion Price. For illustrative example only, if the application of clause (ii) of

the definition of Conversion Price set forth above would result in a Conversion Price of $0.02 and the Borrower converts $1,000,000 aggregate

principal amount and accrued but unpaid interest of this Note, then, for such purposes, (i) the Note would convert at the Floor Price

into 20,000,000 shares of Common Stock ($1,000,000 divided by $0.05), (ii) the Assumed Conversion Price would be $0.02 and (iii) the Borrower

would owe a cash payment of $600,000 (30,000,000, which equals the difference between the 50,000,000 shares issuable upon conversion of

$1,000,000 at an Assumed Conversion Price of $0.02 and the 20,000,000 Conversion Shares actually issued at the Floor Price, multiplied

by the Assumed Conversion Price of $0.02). Upon the exercise of any conversion, the Lender shall duly notify the Borrower whether principal

or interest is being converted. If the Issuer’s Common Stock is chilled for deposit at DTC, becomes chilled, or receives a Stop

Sign or other trading restrictions at any point while this Note remains outstanding, an additional 10% discount will be attributed to

the Conversion Price defined hereof and the conversion dollar amount per conversion shall be reduced by a flat fee of $1,500.00 charged

to the Borrower to cover costs associated with the deposit of chilled or otherwise trade restricted stocks for each conversion. The Borrower

will not be obligated to issue fractional Conversion Shares. In the event that Lender elects to convert the note in part, the conversion

price for each conversion event shall be calculated at the time of conversion in part. The Lender may convert this Note into Common Stock

by providing the Company, with the form of conversion notice attached to the Note as Exhibit B, executed by the Lender evidencing

such Lender’s intention to convert the Note together with the documents set forth in Section 10 hereof. For purposes of this Agreement,

the Clearing Date shall be on the date in which the conversion shares are deposited into the Lender’s brokerage account and Lender’s

broker has confirmed with Lender that the Lender may execute trades of the conversion shares; provided that the registration for resale

of the Conversion Shares under the 1933 Act is effective as of such date or an exemption from the registration requirements under the

1933 Act is available as of such date. The outstanding interest or principal amounts, as determined by the Lender, shall be reduced by

the total dollar amount of Common Stock so converted.

The Company will not issue fractional

shares or script representing fractions of shares of Common Stock on conversion, but the Company will round the number of shares of Common

Stock issuable up to the nearest whole share. The date on which a Notice of Conversion is given shall be deemed to be the date on which

the Lender notifies the Company of its intention to so convert by delivery, by facsimile transmission, email, or otherwise, of a copy

of the Notice of Conversion. Notice of Conversion may be sent by email to the Company, attn: Chief Executive Officer or as otherwise instructed

by the Borrower to Lender in writing. At the Maturity Date, the Company will pay any unconverted outstanding principal amount and accrued

interest thereon, at the option of the Company, in either (a) cash or (b) Common Stock valued at a price equal to the Conversion Price

determined as if the Note was converted in accordance with its terms into Common Stock on the Maturity Date.

Notwithstanding anything to the contrary

in this Note, in no event shall the Lender be entitled to convert that number of Conversion Shares, which when added to the sum of the

number of shares of Common Stock beneficially owned (as such term is defined under Section 13(d) and Rule 13d-3 of the 1934 Act), by the

Lender, would exceed 4.99% of the number of shares of Common Stock outstanding on any date Lender requests conversion, as determined in

accordance with Rule 13d-1(j) of the 1934 Act (the “Ownership Threshold”).

For the avoidance of doubt, the Conversion

Price and number of Conversion Shares shall be subject to adjustment in proportion to any stock split, reverse stock split, share combination

or other similar corporate event.

6. Delivery of Share Certificates Upon Conversion. Upon receipt by the Borrower from the Lender of

a facsimile transmission (with receipt confirmation from recipient) or e-mail (or other reasonable means of communication) of a Notice

of Conversion meeting the requirements for conversion as provided in Section 5, the Borrower shall issue and deliver or cause to be issued

and delivered to or upon the order of the Lender, certificates for the Common Stock issuable upon such conversion within two (2) business

days after such receipt (the “Deadline”) (and, solely in the case of conversion of the entire unpaid principal

amount hereof, surrender of this Note) in accordance with the terms hereof. The Borrower will bear all costs related to the issuance of

the Conversion Shares, including all costs of obtaining an attorney’s opinion letter regarding the Conversion, and the overnight

delivery of the Conversion Shares.

7. Delivery of Common Stock by Electronic Transfer. In lieu of delivering physical certificates representing

the Common Stock issuable upon conversion, provided the Borrower is participating in the Depository Trust Company (“DTC”)

Fast Automated Securities Transfer (“FAST”) program, upon request of the Lender and its compliance with the provisions

of this Note, the Borrower shall use its best efforts to cause its transfer agent to electronically transmit the Common Stock issuable

upon conversion to the Lender by crediting the account of Lender’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission

(“DWAC”) system, provided the stock underlying the Note is eligible for an exemption from registration under the

Securities Act of 1933.

8. Concerning the Shares. The shares of Common Stock issuable upon conversion of this Note may not

be sold or transferred unless (i) such shares are sold pursuant to an effective registration statement under the Act or (ii) the Lender

or its transferee shall have furnished an opinion of counsel to the Company and the Company’s transfer agent (which opinion shall

be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the shares to be sold

or transferred may be sold or transferred pursuant to an exemption from such registration or (iii) such shares are sold or transferred

pursuant to Rule 144 under the Act (or a successor rule) (“Rule 144”). Subject to the removal provisions set forth

below), until such time as the shares of Common Stock issuable upon conversion of this Note have been registered under the Act or otherwise

may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately

sold, each certificate for shares of Common Stock issuable upon conversion of this Note that has not been so included in an effective

registration statement or that has not been sold pursuant to an effective registration statement or an exemption that permits removal

of the legend, shall bear a legend substantially in the following form, as appropriate:

“NEITHER THE ISSUANCE AND SALE

OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE HAVE BEEN REGISTERED

UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED

OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED,

OR (B) AN OPINION OF COUNSEL (WHICH COUNSEL SHALL BE SELECTED BY THE LENDER) , IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT

REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT, NOTWITHSTANDING THE FOREGOING, THE SECURITIES

MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”

The legend set forth above shall be

removed and the Borrower shall issue to the Lender a new certificate therefore free of any transfer legend if (i) the Borrower or its

transfer agent shall have received an opinion of counsel to the effect that a public sale or transfer of such Common Stock may be made

without registration under the Act, which opinion shall be reasonably acceptable to the Company so that the sale or transfer is effected

or (ii) in the case of the Common Stock issuable upon conversion of this Note, such security is registered for sale by the Lender under

an effective registration statement filed under the Act or otherwise may be sold pursuant to Rule 144 without any restriction as to the

number of securities as of a particular date that can then be immediately sold. The Company shall not unreasonably object to the legal

opinion in the event an exemption is available.

The Common Stock issuable upon conversion

of this Note shall be eligible for registration under the Securities Act of 1933, as amended, and the rules and regulations promulgated

thereunder, and applicable state securities laws, pursuant to any registration statements on Form S-1 or otherwise filed by the Company

on a date following the execution of this Note.

9. Registration Statement. On or prior to July 1, 2026, the Company shall prepare and file with the

Securities and Exchange Commission a Registration Statement covering the resale of all of the shares issuable upon conversion of the Note

pursuant to section 6 hereof (the “Registrable Securities”) for an offering to be made on a continuous basis pursuant to Rule

415 or, if Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of Registrable

Securities as the Holders may reasonably specify (the “Initial Registration Statement”). The Initial Registration Statement

shall be on Form S-3 (except if the Company is then ineligible to register for resale of the Registrable Securities on Form S-3, in which

case such registration shall be on such other form available to register for resale of the Registrable Securities as a secondary offering).

in the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule

415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each

of the holders thereof and use its commercially reasonable efforts to file amendments to the Initial Registration Statement as required

by the Commission and/or (ii) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration

Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the Commission,

on Form S-3 or such other form available to register for resale the Registrable Securities as a secondary offering; provided, however,

that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its commercially reasonable efforts

to advocate with the Commission for the registration of all of the Registrable Securities in accordance with the SEC Guidance. In the

event the Company amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (i)

or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission

or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-3 or

such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration

Statement, as amended, or the New Registration Statement (the “Remainder Registration Statements”).

10. Reserved.

11. Prepayment of the Borrower. The Borrower may, at any time and from time to time, prepay all or

part of the amount owing hereunder with a premium of 120% to the principal face value.

12. Agreement of Lender. In the event that the Lender elects to convert the outstanding principal above,

the Lender agrees to execute such mutually acceptable documents, including a subscription agreement and/or conversion notice, as the Borrower

shall reasonably request to ensure compliance with applicable laws, including U.S. federal, state and applicable Canadian securities laws.

The obligations of the Borrower to issue securities to the Lender hereunder shall be contingent upon Lender’s execution of such

documents, when required.

13. Events of Default. If any of the following events of default (each, an “Event of Default”) shall occur:

a. Failure to Pay Principal or Interest. The Borrower fails to pay the principal hereof or interest thereon when due on this Note,

whether at maturity, upon acceleration or otherwise.

b. Conversion and the Shares. Solely due to the fault of the Borrower, the Borrower fails to issue shares of Common Stock to the

Lender (or announces or threatens in writing that it will not honor its obligation to do so) upon exercise by the Lender of the conversion

rights of the Lender in accordance with the terms of this Note, fails to transfer or cause its transfer agent to transfer or issue (electronically

or certificated form) any certificate for shares of Common Stock issued to the Lender upon conversion of or otherwise pursuant to this

Note as and when required by this Note, the Borrower directs its transfer agent not to transfer or delays, impairs, and/or hinders its

transfer agent in transferring (or issuing) (electronically or in certificated form) any certificate for shares of Common Stock to be

issued to the Lender upon conversion of or otherwise pursuant to this Note as and when required by this Note, or fails to remove (or directs

its transfer agent not to remove or impairs, delays, and/or hinders its transfer agent from removing) any restrictive legend (or to withdraw

any stop transfer instructions in respect thereof) on any certificate for any shares of Common Stock issued to the Lender upon conversion

of or otherwise pursuant to this Note as and when required by this Note (or makes any written announcement, statement or threat that it

does not intend to honor the obligations described in this paragraph) and any such failure shall continue uncured (or any written announcement,

statement or threat not to honor its obligations shall not be rescinded in writing) for ten (10) business days after the Lender shall

have delivered a Notice of Conversion, providing that the Company counsel does not reasonably object to the legal opinion in conclusion

that an exemption is available.

c. Breach of Covenants. The Borrower breaches any material covenant or other material term, or condition contained in this Note

and any collateral documents and such breach continues for a period of ten (10) days after written notice thereof to the Borrower from

the Lender.

d. Breach of Representations and Warranties. Any representation or warranty of the Borrower made herein or in any agreement, statement

or certificate given in pursuant hereto or in connection herewith shall be false or misleading in any material respect when made and the

breach of which has (or with the passage of time will have) a material adverse effect on the rights of the Lender with respect to this

Note.

e. Receiver or Trustee. The Borrower or any subsidiary of the Borrower shall make an assignment for the benefit of creditors or

apply for or consent to the appointment of a receiver or trustee for it or for a substantial part of its property or business, or such

a receiver or trustee shall otherwise be appointed.

f. Judgments. Any money judgment, writ or similar process shall be entered or filed against the Borrower or any subsidiary of

the Borrower or any of its property or other assets for more than $500,000, and shall remain unvacated,

unbonded or unstayed for a period of sixty (60) days unless otherwise consented to by the Lender, which consent will not be unreasonably

withheld.

g. Bankruptcy. Bankruptcy, insolvency, reorganization or liquidation proceedings or other proceedings, voluntary or involuntary,

for relief under any bankruptcy law or any law for the relief of debtors shall he instituted by or against the Borrower which has not

been dismissed 60 days after its filing.

h. Liquidation. Any dissolution, liquidation, or winding up of Borrower or any substantial portion of its business.

i. Cessation of Operations. Any cessation of operations by Borrower or Borrower admits it is otherwise generally unable to pay

its debts as such debts become due, provided, however, that any disclosure of the Borrower’s ability to continue as a “going

concern” shall not be an admission that the Borrower cannot pay its debt as they become due.

j. Remedies. UPON THE OCCURRENCE AND DURING THE CONTINUATION OF ANY EVENT OF DEFAULT SPECIFIED IN SECTION 13, THE NOTE SHALL BECOME

IMMEDIATELY DUE AND PAYABLE AND THE BORROWER SHALL PAY TO THE LENDER, IN FULL SATISFACTION OF ITS OBLIGATIONS HEREUNDER, AN AMOUNT

EQUAL TO THE DEFAULT SUM (AS DEFINED

HEREIN). Upon the occurrence and during the continuation of any Event of Default, the Lender shall deliver a written notice to the Borrower

(the “Default Notice”), which shall set forth the Event of Default that such notice is based upon and the calculation

of all the payments, including the Default Sum, if any, due to the Lender (the “Default Payment Calculation”),

the Note shall become immediately due and payable. Unless otherwise objecting to the Event of Default or the Default Payment Calculation

set forth in the Default Notice, which shall be reasonable and shall be reviewed or adjusted by the Lender if necessary (the “Amended

Default Notice”), the Borrower shall pay to the Lender, in full satisfaction of its obligations hereunder, an amount equal

to (w) then outstanding principal amount of this Note plus (x) accrued and unpaid interest on the unpaid principal amount of this Note

to the date of payment (the “Mandatory Prepayment Date”) plus (y) Default Interest, if any, and all other amounts

payable hereunder shall immediately become due and payable, all without demand, presentment or notice, all of which hereby are expressly

waived, together with all costs, including, without limitation, legal fees and expenses, of collection, and the Lender shall be entitled

to exercise all other rights and remedies available at law or in equity(collectively, the “Default Sum”). If

the Borrower fails to pay the Default Amount within fifteen (15) business days of the latter of the date when Default Notice is provided,

or the date of the Amended Default Notice, then the Lender shall have the right at any time, so long as the Borrower remains in default

(and so long and to the extent that there are sufficient authorized shares), to require the Borrower, upon written notice, to immediately

issue, in lieu of the Default Sum, the number of shares of Common Stock of the Borrower equal to the Default Amount divided by the Conversion

Price then in effect.
