Note Modification and Conversion Agreement

On April 24, 2026, Profusa,

Inc. (the “Company”) entered into that certain Note Modification and Conversion Agreement (the “Agreement”)

with NorthView Sponsor I LLC (the “Holder”), to amend that certain Promissory Note dated as of April 27, 2023, as

amended and restated on January 8, 2024 and as further amended on May 31, 2024 and March 20, 2026 (as so amended, the “Note”),

in the original principal amount of up to $2,500,000.

Pursuant to the Agreement,

the Note was amended to provide for the following terms: (i) the outstanding principal amount of the Note is $1,869,796; (ii) the Note

is non-interest bearing; (iii) the maturity date is December 31, 2026; and (iv) the Holder has the option to convert all or any portion

of the outstanding principal balance of the Note into shares of the Company’s common stock, par value $0.0001 per share (“Common

Stock”), at any time, or from time to time, following the effectiveness of a registration statement registering the resale of

the shares issuable upon conversion (the “Conversion Shares”). The conversion price per share is equal to the greater

of (i) ninety-five percent (95%) of the closing price of the Common Stock on the applicable conversion date and (ii) $0.35 per share.

The number of Conversion Shares issuable upon conversion shall be determined by dividing the principal amount being converted by the conversion

price. The conversion is subject to a beneficial ownership limitation of 4.99% of the outstanding shares of Common Stock.

The foregoing description

of the Agreement is summary in nature and is qualified in its entirety by reference to the full text of the Agreement, a copy of which

is filed as Exhibit 10.1 hereto and is incorporated by reference herein.

Amendment No. 1 to Note Modification and Conversion Agreement

On April 29, 2026, the Company entered into Amendment No. 1 to the Note Modification and Conversion Agreement

(the “Amendment”) with the Holder, to amend

the Agreement described above. Pursuant to the Amendment, the Agreement was amended to (i) add a covenant restricting the issuance of

Conversion Shares in excess of 19.99% of the number of shares of Common Stock issued and outstanding as of the date of the Agreement (the

“Exchange Cap”) unless and until the Company obtains stockholder approval in accordance with the applicable rules and

regulations of Nasdaq (“Stockholder Approval”) or an exception to such Stockholder Approval requirements is available,

and (ii) require the Company to seek Stockholder Approval at a meeting of stockholders (or by written consent) within 90 days following

the date of the Amendment, and every four months thereafter if not obtained.

The foregoing description of the Amendment is summary in nature and is qualified in its entirety by reference

to the full text of the Amendment, a copy of which is filed as Exhibit 10.2 hereto and is incorporated by reference herein.

Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On April 28, 2026, the Company received written notification from the

Nasdaq Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”)

that the Company had not regained compliance with Nasdaq Listing Rule 5450(b)(1)(C), which requires companies listed on The Nasdaq Global

Market to maintain a minimum market value of publicly held shares of $15,000,000 (the “MVPHS Rule”). The Staff originally

notified the Company of this deficiency on October 27, 2025, and in accordance with Listing Rule 5810(c)(3)(D), provided the Company 180

calendar days, or until April 27, 2026, to regain compliance. The Company did not regain compliance by the deadline. The Nasdaq Hearings

Panel (the “Panel”) will consider this matter in connection with its pending decision regarding the Company’s

separate deficiencies under Nasdaq Listing Rule 5450(a)(1) and 5450(b)(2)(a), which require companies listed on The Nasdaq Global Market

to maintain a minimum closing bid price of $1.00 per share (the “Bid Price Rule”) and a minimum market value of listed

securities of $50 million (the “MVLS Rule”).

In connection with the April 28, 2026 deficiency letter described above,

the Company has been provided with an opportunity to present its views regarding the deficiency under the MVPHS Rule to the Panel in writing

no later than May 5, 2026. The Company intends to respond to the Panel and address the deficiency under the MVPHS Rule in its written

submission. There can be no assurance that the Panel will grant the Company’s request for continued listing.

Item 3.03. Material

Modifications to Rights of Security Holders.

On April 29, 2026, the Company and Ascent Partners Fund LLC (the “Holder”)

entered into an amendment (the “Amendment”) to that certain Warrant to Purchase

Shares of Common Stock of the Company, dated as of April 20, 2026 (the “Warrant”).

The Warrant was issued in connection with a Securities Purchase Agreement, dated as of February 11, 2025, between the Company and the

Holder.

The Warrant entitles the Holder to purchase up to 3,333,333 shares

of the Company’s common stock, par value $0.0001 per share (the “Common Stock”),

at an exercise price of $0.50 per share, subject to adjustment, exercisable until April 20, 2031. The Warrant is subject to the terms

and conditions set forth therein, including provisions relating to exercise procedures, adjustments upon certain corporate events, and

notices.

Pursuant to the Amendment,

Section 4 (Treatment of Consideration in Fundamental Transactions) of the Warrant was deleted in its entirety and replaced with “Reserved.”

Prior to the Amendment, Section 4 provided that (a) in certain Fundamental Transactions where the consideration payable to holders of

the underlying securities consisted solely of cash and marketable securities and exceeded the exercise price, the Warrant would automatically

convert into the right to receive the net consideration that would have been payable on the underlying shares, and (b) in other Fundamental

Transactions, the acquiring or successor entity would assume the Warrant and the Company’s obligations thereunder. As a result of

the Amendment, the Warrant no longer contains these automatic conversion or assumption provisions with respect to Fundamental Transactions.

All other provisions of the Warrant remain in full force and effect.

The foregoing description

of the Amendment is summary in nature and is qualified in its entirety by reference to the full text of the Amendment, a copy of which

is filed as Exhibit 10.3 hereto and is incorporated by reference herein.

2.7 Compliance

with Law. The Conversion Shares shall not be issued upon conversion of the Note unless such issuance and such conversion comply with

all applicable provisions of law.

2.8 Beneficial

Ownership Limitation.

(a) Notwithstanding

anything to the contrary contained herein, the Company shall not effect the conversion of any portion of the Note, and the Holder shall

not have the right to convert any portion of the Note, to the extent that, after giving effect to such conversion, the Holder (together

with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s Affiliates

(such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as

defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its

Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon conversion of the Note with respect

to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion

of the remaining, unconverted principal amount of the Note beneficially owned by the Holder or any of its Affiliates or Attribution Parties

and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company subject to a limitation

on conversion or exercise analogous to the limitation contained herein (including, without limitation, any other convertible notes or

warrants) beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence,

for purposes of this Section 2.8, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange

Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder. To the extent that

the limitation contained in this Section 2.8 applies, the determination of whether the Note is convertible (in relation to other securities

owned by the Holder together with any Affiliates and Attribution Parties) and of how much principal amount of the Note is convertible

shall be in the sole discretion of the Holder, and the submission of a notice of conversion shall be deemed to be the Holder’s determination

of whether the Note may be converted (in relation to other securities owned by the Holder together with any Affiliates and Attribution

Parties) and how much principal amount of the Note is convertible, in each case subject to the Beneficial Ownership Limitation. To ensure

compliance with this restriction, the Holder will be deemed to represent to the Company each time it delivers a notice of conversion that

such notice of conversion has not violated the restrictions set forth in this Section 2.8 and the Company shall have no obligation to

verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall

be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.

(b) The

“Beneficial Ownership Limitation” shall be 4.99% of the number of shares of Common Stock outstanding immediately after

giving effect to the issuance of shares of Common Stock issuable upon conversion of the Note held by the Holder. The Holder, upon delivery

of not less than sixty-one (61) days’ prior written notice to the Company, may increase or decrease the Beneficial Ownership Limitation

provisions of this Section 2.8; provided that the Beneficial Ownership Limitation in no event shall exceed 9.99% of the number of shares

of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of the Note held

by the Holder, and any such increase or decrease will not be effective until the sixty-first (61st) day after such notice is delivered

to the Company. The provisions of this Section 2.8 shall be construed and implemented in a manner otherwise than in strict conformity

with the terms of this Section 2.8 to correct this subsection (or any portion hereof) which may be defective or inconsistent with the

intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect

to such limitation. The limitations contained in this Section 2.8 shall apply to a successor holder of the Note.

purposes of this Section 2.8, “Affiliate” means any Person that, directly or indirectly through one or more intermediaries,

controls or is controlled by or is under common control with the Holder, as such terms are used in and construed under Rule 405 under

the Securities Act of 1933, as amended. “Person” means an individual or corporation, partnership, trust, incorporated

or unincorporated association, joint venture, limited liability company, joint stock company, government (or an agency or subdivision

thereof) or other entity of any kind.

and to provide for the conversion of the Note into shares of the Company’s common stock, par value $0.0001 per share (the “Common

Stock”), on the terms and subject to the conditions set forth therein;

WHEREAS, the Common

Stock is listed on the Nasdaq Stock Market LLC (“Nasdaq”), and the applicable rules and regulations of Nasdaq (the

“Nasdaq Rules”) require, among other things, that the Company obtain stockholder approval prior to the issuance of

shares of Common Stock in connection with certain transactions where such issuance equals or exceeds 19.99% of the number of shares of

Common Stock outstanding before such issuance;

WHEREAS, the Parties

desire to amend the Agreement to add a covenant restricting the issuance of Conversion Shares (as defined in the Agreement) in excess

of the Exchange Cap (as defined below) unless and until the Company has obtained the requisite stockholder approval in accordance with

the Nasdaq Rules;

WHEREAS, Section 6.5

of the Agreement provides that any amendment to the Agreement may be made with, and only with, the written consent of the Company and

the Holder; and

WHEREAS, the Parties

desire to amend the Agreement as set forth herein.

the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

ARTICLE

(a) “Exchange

Cap” means 19.99% of the number of shares of Common Stock issued and outstanding as of the date of the Agreement (the “Measurement

Date”), as such number may be adjusted for any stock split, stock dividend, stock combination, recapitalization, or other similar

transaction effected after the Measurement Date.

(b) “Exchange

Cap Shares” means the maximum number of shares of Common Stock that may be issued as Conversion Shares without exceeding the Exchange

Cap, taking into account all shares of Common Stock previously issued as Conversion Shares pursuant to the Agreement on or after the Measurement

Date.

other percentage as may be required by the Nasdaq Rules and the Company’s organizational documents) to approve the issuance of Conversion

Shares in excess of the Exchange Cap in connection with the transactions contemplated by the Agreement, as may be required by the Nasdaq

Rules.

ARTICLE

EXCHANGE CAP LIMITATION

2.1 Exchange

Cap Covenant. The following new Section 2.9 is hereby added to the Agreement immediately following Section 2.8 thereof:

“2.9. Exchange Cap Limitation.

(a) Notwithstanding

anything to the contrary contained in this Agreement, the Company shall not issue, and the Holder shall not have the right to receive

upon conversion of the Note, any Conversion Shares to the extent that, after giving effect to such issuance, the aggregate number of shares

of Common Stock issued as Conversion Shares pursuant to this Agreement would exceed the Exchange Cap, unless and until (i) the Company

shall have obtained Stockholder Approval in accordance with the Nasdaq Rules or (ii) an exception to the stockholder approval requirements

of the Nasdaq Rules is available with respect to such issuance, as determined in good faith by the Company’s board of directors

based on written advice of outside legal counsel.

(b) In

the event that the Holder delivers a Conversion Notice requesting conversion of a principal amount of the Note that would result in the

issuance of Conversion Shares in excess of the Exchange Cap (and Stockholder Approval has not been obtained), the number of Conversion

Shares issuable upon such conversion shall automatically be reduced to the maximum number of shares that may be issued without exceeding

the Exchange Cap, and the corresponding principal amount of the Note to be converted shall be reduced accordingly. Any portion of the

principal amount of the Note that is not converted as a result of the foregoing limitation shall remain outstanding and shall continue

to be subject to conversion in accordance with this Agreement, subject to the Exchange Cap limitation set forth in this Section 2.9 and

the other terms and conditions of this Agreement.

the avoidance of doubt, the limitation set forth in this Section 2.9 shall be applied independently of, and in addition to, the Beneficial

Ownership Limitation set forth in Section 2.8 of the Agreement, and both limitations must be satisfied at the time of any conversion.

In the event of a conflict between the Exchange Cap limitation and the Beneficial Ownership Limitation, the more restrictive limitation

shall control.

(d) The

Company shall maintain records of the aggregate number of Conversion Shares issued under this Agreement following the Measurement Date

and shall make such records available to the Holder upon reasonable request. The Company shall promptly notify the Holder in writing at

any time the aggregate number of Conversion Shares theretofore issued under this Agreement equals or exceeds 90% of the Exchange Cap Shares.

(e) The

Exchange Cap limitation set forth in this Section 2.9 shall terminate and be of no further force or effect upon the earliest to occur

of: (i) the date on which Stockholder Approval is obtained, (ii) the date on which the Common Stock is no longer listed on Nasdaq or any

other national securities exchange requiring stockholder approval for issuances of common stock in excess of 19.99% of the outstanding

shares, or (iii) a determination by the Company’s board of directors, based on written advice of outside legal counsel, that Stockholder

Approval is not required under the Nasdaq Rules with respect to the issuance of Conversion Shares under this Agreement.”

ARTICLE

3.1 Stockholder

Approval Obligation. The following new Section 5.4 is hereby added to the Agreement immediately following Section 5.3 thereof:

from its stockholders in connection therewith in the same manner as all other management proposals in such proxy statement and all management-appointed

proxyholders shall vote their proxies in favor of such proposal.

every four (4) months thereafter to seek Stockholder Approval until the earlier of (i) the date on which Stockholder Approval is obtained

and (ii) the date on which the Note has been repaid or fully converted in accordance with the terms of the Agreement, subject to the limitations

set forth herein.

the foregoing, the Company may at its election obtain Stockholder Approval by means of a written consent signed by the holders of outstanding

stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which

all shares entitled to vote thereon were present and voted, and if the Company elects to obtain Stockholder Approval by means of such

a written consent, it shall file with the SEC and mail an information statement in compliance with all applicable laws and regulations.

(d) Prior

to any such stockholder meeting or written consent solicitation, the Company shall timely file a proxy statement or information statement,

Re: Amendment No. 4

Dear Fred:

Reference is made to the Warrant to Purchase Shares

of Common Stock of Profusa, Inc., a Delaware corporation (together with its successors and permitted assigns, the “Company”),

issued by the Company on April 20, 2026 for the benefit of Ascent Partners Fund LLC, a Delaware limited liability company (“Ascent”),

as Holder (the “Warrant”; capitalized terms used but not defined herein are used as defined in the Warrant, including

as defined by reference to the Purchase Agreement).

Subject to the terms and conditions set forth

herein, and effective on the date hereof (the “Amendment Effective Date”), the Warrant is hereby amended as follows:

Warrant

● Section 4 is hereby deleted in its entirety and replaced with “Reserved.”

This amendment is a Transaction Document and is

limited as written. As of the date first written above, each reference in the Warrant to “this Warrant,” “hereunder,”

“hereof,” “herein,” or words of like import, and each reference in the other Transaction Documents

to the Warrant (including, without limitation, by means of words like “thereunder,” “thereof” and

words of like import), shall refer to the Warrant as modified thereby, and the provisions in this amendment amending the Warrant shall

be read together and construed as a single agreement with the Warrant. The execution, delivery and effectiveness of this amendment shall

not, except as expressly provided herein, (A) waive or modify any Default or Event of Default (whether or not existing on the date

hereof), right, power or remedy under, or any other provision of, any Transaction Document (in each case, other than any failure to comply

with any provision of a Transaction Document amended hereby that would not have been a failure if such Transaction Document had been amended

as provided herein prior to the date hereof) or (B) commit or otherwise obligate the Holder or the Collateral Agent to enter into

or consider entering into any other consent, waiver or modification of any Transaction Document or make any further purchases or other

advances pursuant to any Transaction Documents.

Each Company Party hereby agrees that it continues

to guaranty, jointly and severally, absolutely, unconditionally and irrevocably, pursuant to the Guaranty, as primary obligor and not

merely as surety, the full and punctual payment when due of the Obligations of any other Company Party owing under the Transaction Document

as modified hereby (subject to the limitations set forth in the Guaranty) and that the terms hereof shall not affect in any way its obligations

and liabilities, as expressly modified hereby, under the Transaction Documents. Each Company Party hereby reaffirms (a) all of its

obligations and liabilities under the Transaction Documents as modified hereby, and agrees that such obligations and liabilities shall

remain in full force and effect and (b) all Liens granted under the Transaction Documents, and agrees that such Liens shall continue

to secure the Obligations.

In further consideration for

the execution of this amendment by the Holder and without limiting any rights or remedies the Holder or any of its Related Parties may

have, each Company Party hereby releases each of the Holder and each of its Related Parties (each a “Releasee” and,

collectively, the “Releasees”) against any and all claims and from any other Losses of any Company Party or any Subsidiary

thereof, whether or not relating to any Transaction Document, any obligation or liability owing thereunder, any asset of any Company Party

or any of their Subsidiaries or Affiliates, or any legal relationship that exists or may exist between any Releasee and any Company Party

or any Subsidiary of any Company Party. Each Company Party, each for itself and for its Subsidiaries, acknowledges and agrees that it

or its Subsidiaries may discover information later that could have affected materially their willingness to agree to the release in this

paragraph and that neither such possibility, which it took into account when executing this amendment, nor such discovery, as to which

it expressly assumes the risk, shall affect the effectiveness of the release in this paragraph, and waives the benefit of any legal requirement

that may provide otherwise.

As a Transaction Document, this amendment is subject

to various interpretative and miscellaneous sections set forth in the Purchase Agreement and other Transaction Documents that apply expressly

to all Transaction Documents, located principally Article VI (Miscellaneous) of the Purchase Agreement (but also, without limitation,

in Section 4.15 (Indemnification of Each Purchaser Party) thereof), including Section 6.2 (Fees and Expenses) thereof (which

provides, without limitation, reimbursement to the Purchaser Parties for fees, costs and expenses of negotiation, preparation, execution

and signing of this amendment or otherwise relating to this amendment or the transactions contemplated herein) and Sections 6.3(a)

(Entire Agreement), 6.3(b) (Amendments), 6.3(c) (Beneficiary; Successors and Assigns), 6.3(d) (No Implied Waivers or Notice Rights), 6.3(e)

(Counterparts), Section 6.3(f) (Electronic Signatures), 6.4 (Notices), 6.7 (Severability) and 6.15 (Interpretation) (containing

various interpretative provisions and additional definitions) thereof. In addition, without limitation, (a) Section 6.6 (Governing

Law; Courts) thereof provides that this amendment shall be governed by and construed in accordance with the laws of the State of Delaware

and that Proceedings in respect hereto shall be brought exclusively in the Delaware state courts sitting in Wilmington, DE or the federal

courts for the District of Delaware sitting in Wilmington, DE (subject to certain exceptions for enforcement Proceedings brought by the

Collateral Agent or any Purchaser Party) and (b) in Section 6.16 (Waiver against Trust), the parties thereto (which include

the parties hereto) thereby irrevocably and unconditionally waived, to the fullest extent permitted by applicable Regulations, any right

that they may have to trial by jury of any claim or cause of action or in any Proceeding, directly or indirectly based upon or arising

out of, under or in connection with, this amendment or the transactions contemplated therein or related thereto (whether founded in contract,

tort or any other theory). The parties hereto hereby reaffirm all of these and all other provisions of the Transaction Documents applying

to the Transaction Documents as applying to this amendment, all of which are hereby incorporated herein by reference. If the Amendment

Effective Date has not occurred within two Business Days after the date hereof, the Collateral Agent may, in its sole discretion upon

notice to the Company, elect to terminate this amendment, at which point this amendment (including the provisions requiring payment of

the Amendment Fee) will be of no further force and effect.
