Item 7. Management’s Discussion and Analysis

of Financial Condition and Results of Operations of PBAX.

The following discussion

and analysis of PBAX’s financial condition and results of operations should be read in conjunction with our audited consolidated

financial statements and the notes related thereto which are included in Item 8 of this Annual Report. Certain information contained in

the discussion and analysis set forth below includes forward-looking statements. Our actual results may differ materially from those anticipated

in these forward-looking statements as a result of many factors, including those set forth under “Cautionary Note Regarding Forward-Looking

Statements,” “Risk Factors” and elsewhere in this Annual Report.

Overview

We are a blank check company

incorporated in Delaware on June 8, 2021. We were formed for the purpose of effecting a merger, capital stock exchange, asset acquisition,

stock purchase, reorganization or similar business combination with one or more target businesses, using cash from the proceeds of our

IPO and the sale of the placement units that occurred simultaneously with the completion of our IPO, our capital stock, debt or a combination

of cash, stock and debt.

We incurred significant costs

in the pursuit of a business combination. As described below, the Business Combination was consummated on February 14, 2024, after the

date of the audited consolidated financial statements included in this Annual Report.

Recent Developments

On January 3, 2024, we held

a special meeting of stockholders (the “Third Special Meeting”). At the Third Special Meeting, our stockholders approved a

proposal to amend the Investment Management Trust Agreement (the “IMTA”), dated as of October 5, 2021, as amended by the Amendment

No. 1 dated December 20, 2022 and Amendment No. 2 dated July 7, 2023, by and between us and Continental Stock Transfer and Trust Company

(“Continental”), to extend the business combination period up to three times for one month each time from January 8, 2024

to February 8, 2024, March 8, 2024 or April 8, 2024 (the “Third IMTA Amendment”). On January 3, 2024, we entered into the

Third IMTA Amendment with Continental. Our stockholders also approved an amendment (the “Third Charter Amendment”) to our

amended and restated certificate of incorporation, as amended by the First Amendment dated December 20, 2022 and the Second Amendment

dated July 7, 2023 (as amended by the Third Charter Amendment, the “PBAX Charter”) the to provide its board of directors the

ability to extend the date by which we have to consummate a business combination up to three times for one month each time, for a maximum

of three additional months. On January 3, 2024, we filed the Third Charter Amendment with the Secretary of State of the State of Delaware,

which was subsequently corrected by a Certificate of Correction (the “Certificate of Correction”) dated January 4, 2024 to

correct certain scrivener’s errors in the Third Charter Amendment.

89

In connection with the approval

of the Third Charter Amendment, holders of 11,625 shares of our Class A common stock, exercised redemption rights. As a result, following

satisfaction of such redemptions, we had 6,234,582 shares of Class A common stock outstanding, of which (i) 753,332 were shares of Class

A common stock issued to the public in our IPO, which shares of Class A common stock were entitled to receive a pro rata portion of the

remaining funds in our trust account (the “Trust Account”) in connection with our initial business combination, a liquidation

or certain other events, (ii) 4,596,250 were shares of Class A common stock issued upon the conversion of an equal number of shares of

our Class B common stock, par value $0.0001 per share (“Class B common stock”), acquired by Phoenix Biotech Sponsor, LLC (“Sponsor”)

prior to our IPO, which shares of Class A common stock did not have redemption rights, and (iii) 885,000 were shares of Class A common

stock included in the private placement units acquired in the private placement by the Sponsor and other investors concurrent with our

IPO, which shares of Class A common stock did not have redemption rights.

On January 4, 2024, the Sponsor

deposited $22,600 in the Trust Account in connection with the extension of the business combination deadline. On January 4, 2024, we made

a series of payments of an aggregate of $128,133 to holders of redeemed Class A common stock (an aggregate of $11.02 per redeemed share).

On

February 5, 2024, the parties entered into Amendment No. 1 to the Business Combination Agreement to, among other things, (i) remove the

minimum cash condition, (ii) modify the stock-price based milestones such that (a) the trading price condition for the First Level Earnout

Target shall be reset from $12.50 to 125% of the Conversion Price of the Series A Preferred Stock (in each case, as defined below) upon

the reset of such Conversion Price as described below and (b) the trading price condition for the Second Level Earnout Target shall be

reset from $15.00 to 150% of the Conversion Price of the Series A Preferred Stock upon reset of such Conversion Price as described below,

and (iii) increase the aggregate number of shares of Class A common stock issuable to the stockholders of CERo in connection with the

Business Combination from 4,651,704 shares to 5,000,000 shares. Such number of shares is in addition to up to 1,200,000 shares issuable

upon satisfaction of certain earn-out conditions and 382,651 shares issuable upon exercise of rollover options or warrants.

On February 8, 2024, we

held a special meeting of stockholders (the “Fourth Special Meeting”). At the Fourth Special Meeting, our stockholders

adopted and approved: (i) the Business Combination Agreement, pursuant to which Merger Sub merged with and into CERo, with CERo

surviving the merger as a wholly-owned subsidiary of PBAX and approved the Business Combination and the other transactions and

ancillary documents contemplated by and required for the Business Combination; (ii) on a non-binding advisory basis, certain changes

to the PBAX Charter, including the name change to CERo Therapeutics Holdings, Inc., share authorizations, and others; (iii) the

issuance of Class A common stock to CERo stockholders pursuant to the Business Combination Agreement; (iv) the election of five

directors; and (v) the 2024 Equity Incentive Plan and the 2024 Employee Stock Purchase Plan, contingent of the consummation of the

Business Combination.

In connection with the approval

of the Business Combination, holders of 671,285 shares of Class A common stock, exercised redemption rights. As a result, following satisfaction

of such redemptions, we had 5,563,297 shares of Class A common stock outstanding, of which (i) 82,047 were shares of Class A common stock issued

to the public in our IPO, which shares of Class A common stock were entitled to receive a pro rata portion of the remaining funds in our

Trust Account in connection with its initial business combination, a liquidation or certain other events, (ii) 4,596,250 were shares of

Class A common stock issued upon the conversion of an equal number of shares of our Class B Shares acquired by Sponsor prior to our IPO,

which shares of Class A common stock did not have redemption rights, and (iii) 885,000 were shares of Class A common stock included in

the private placement units acquired in the private placement by the Sponsor and other investors concurrent with our IPO, which shares

of Class A common stock did not have redemption rights. On February 14, 2024, we made a series of payments of an aggregate of $7,456,463.30

to holders of redeemed Class A common stock (an aggregate of $11.11 per redeemed share).

On February 13, 2024, the parties entered into Amendment No. 2 to the

Business Combination Agreement to create two additional pools of Earnout Shares of Class A common stock, one pool of which contained 875,000

shares, which were fully vested at closing of the Business Combination and which were issued as an offset to the agreement by Sponsor

to forfeit an offsetting number of shares, and one pool of which will contain 1,000,000 shares, which will be fully vested upon the achievement

of certain regulatory milestone-based earnout targets and make certain other technical changes to the timing and process for issuance

of the 1,200,000 shares of Class A common stock subject to the other earn-out conditions set forth in the Business Combination Agreement.

90

On February 14, 2024, the

Business Combination between Legacy CERo and PBAX was consummated pursuant to the Business Combination Agreement.

At the effective time of

the Business Combination (the “Effective Time”), (i) each outstanding share of Legacy CERo common stock, (the “Legacy

CERo common stock”), was cancelled and converted into the right to receive shares of Common Stock of PBAX; (ii) each outstanding

option to purchase Legacy CERo common stock was converted into an option to purchase shares of Common Stock; (iii) each outstanding share

of CERo preferred stock, was converted into the right to receive shares of Common Stock, and (iv) each outstanding warrant to purchase

CERo preferred stock (the “Legacy CERo warrants”) was converted into a warrant to acquire shares of Common Stock. In addition,

each outstanding Legacy CERo convertible bridge note was exchanged for shares of Series A Preferred Stock.

In addition, the holders

of Legacy CERo common stock and Legacy CERo preferred stock have the contingent right to receive additional shares of Common Stock (the

“Earnout Shares”). At the closing of the Business Combination (the “Closing”), we issued three pools of shares

subject to forfeiture if the applicable conditions to transferability thereof are not satisfied: (i) 1,200,000 shares of Common Stock,

which will be fully vested upon the achievement of certain adjusted stock price-based earnout targets or upon a qualifying transaction

(ii) 875,000 shares of Common Stock, pursuant to a Letter Agreement, dated as of February 14, 2024 (the “Sponsor Share Forfeiture

Agreement”) which were fully vested at Closing of the Business Combination and which were issued as an offset to the Sponsor Share

Forfeiture Agreement, and (iii) 1,000,000 shares of Common Stock, which will be fully vested upon to achievement of certain regulatory

milestone-based earnout targets.

As consideration for the

Business Combination, we issued to Legacy CERo stockholders an aggregate of 7,597,638 shares of Common Stock, including 2,200,000 Earnout

Shares and 382,651 shares issuable upon exercise of rollover options or warrants.

On February 14, 2024, we

sold 10,080 shares of Series A Preferred Stock, 612,746 Common Warrants and 2,500 Preferred Warrants pursuant to the Amended and Restated

Securities Purchase Agreement, dated February 14, 2024, by and among the Company, CERo and certain accredited investors (the “Initial

Investors”) for aggregate cash proceeds of approximately $9.98 million. A portion of the issued Series A Preferred Stock were issued

as condition for extinguishment of indebtedness.

On February 14, 2024, we

entered into a common stock purchase agreement (the “First ELOC”) with an investor which allows us to elect at our sole discretion

to sell and issue, up to the lesser of $25 million or a limit determined by maximum ownership percentages. As consideration for executing

this agreement, we refunded $1 million of the proceeds of the Series A financing to the investor and $150,000 to investor counsel.

On February 23, 2024, we

entered into a purchase agreement (the “Second ELOC”) with an investor which allows us to elect at our sole discretion to

sell and issue, up to the lesser of $25 million or a limit determined by maximum ownership percentages following the termination of the

First ELOC, including as a result of the sale of the maximum amount permitted under such First ELOC or the expiration of the First ELOC

at the end of its three-year term. As consideration for executing this agreement, we will issue $500,000 of Common Stock with a per share

price determined by the five-day volume weighted average daily common share price on the five days preceding the effectiveness of the

registration statement that includes the shares pursuant to the purchase agreement.

On April 1, 2024, we sold

626 shares of Series B Preferred Stock pursuant to the Securities Purchase Agreement, dated March 28, 2024, by and among us and certain

accredited investors for aggregate cash proceeds of approximately $0.5 million.

Results of Operations

As of December 31, 2023,

we had not commenced any operations. All activity through December 31, 2023 relates to our formation, the IPO, and since the IPO, the

search for a prospective initial business combination. We will not generate any operating revenues until after the completion of a business

combination, at the earliest. We generate non-operating income in the form of interest income from the proceeds derived from the IPO placed

in the Trust Account.

For the year ended December 31, 2023, we had a net loss of $2,536,233,

which primarily consists of operating expenses of $2,892,935 and Delaware franchise taxes of $40,050, partially offset by the interest

earned on marketable securities held in Trust Account of $491,571.

91

For the year ended December

31, 2022, we had a net loss of $667,736, which primarily consists of operating expenses of $2,841,391 and Delaware franchise taxes of

$64,050, partially offset by the interest earned on marketable securities held in Trust Account of $2,836,864.

Liquidity and Going Concern

On October 8, 2021,

we consummated the IPO of 17,500,000 units (“Units”), at a price of $10.00 per Unit, which included the partial exercise by

the underwriter of its over-allotment option in the amount of 2,000,000 Units, generating gross proceeds of $175,000,000. Simultaneously

with the closing of the IPO, we consummated the sale of 885,000 units (the “Private Placement Units”) to the Sponsor, Cantor

Fitzgerald & Co. (“Cantor”) and Cohen & Company Capital Markets, a division of J.V.B. Financial Group, LLC (“CCM”)

at a price of $10.00 per Private Placement Unit, generating gross proceeds of $8,850,000.

Following the IPO, the partial

exercise of the over-allotment option and the sale of the Private Placement Units, a total of $178,500,000 was placed in the Trust Account

($10.20 per Unit). We incurred $12,729,318 in transaction costs, including $2,635,000 of underwriting fees, $9,150,000 of deferred underwriting

fees and $944,318 of other offering costs.

As of December 31, 2023,

we had $96,873 in our operating bank accounts, $8,436,311 in money market funds held in Trust Account to be used for a business combination

or to repurchase or redeem our Public Shares in connection therewith and a working capital deficit of $5,049,122.

For the year ended December 31, 2023, there was $1,523,604 of cash

used in operating activities.

For the year ended December

31, 2022, there was $1,092,247 of cash used in operating activities.

We used substantially all

of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less taxes payable),

to complete our Business Combination, including the payment of transaction costs.

In order to finance transaction

costs in connection with a business combination, our Sponsor or an affiliate of our Sponsor or certain of our officers and directors may,

but are not obligated to, loan us funds as may be required. If we complete a business combination, we may repay such loaned amounts out

of the proceeds of the Trust Account released to us. In the event that a business combination does not close, we may use a portion of

the working capital held outside the Trust Account to repay such loaned amounts, but no proceeds from our Trust Account would be used

for such repayment. Up to $1,500,000 of such loans may be converted into units of the post business combination entity, at a price of

$10.00 per unit, at the option of the lender. The units would be identical to the Private Placement Units. On December 13, 2022,

we entered into a promissory note with the Sponsor. In order to fund ongoing operations, the Sponsor will loan up to $1,500,000 to us.

On December 8, 2023, the Promissory Note was amended to increase the aggregate amount from $1,500,000 to $1,600,00. As of December 31,

2023 and 2022, there was $1,555,000 and $650,000 of outstanding borrowings under the working capital loan arrangement, respectively. On

February 14, 2024, the Sponsor surrendered the Promissory Note to us in payment of its subscription price for Series A Preferred Stock

in the financing transaction described above.

Our ability to continue as

a going concern is dependent on its ability to raise additional capital to fund its R&D activities and meet its obligations on a timely

basis. Since inception, we have incurred net losses and operating cash flow deficits, resulting in an accumulated deficit of $43.3 million

as of December 31, 2023. On February 14, 2024, we acquired the assets of CERo Therapeutics, Inc., closed a private placement with

gross proceeds of $9.8 million, and assumed the R&D operations of Legacy CERo. Additional funds are necessary to maintain current

operations and to continue R&D activities. However, there can be no assurance that sufficient funding will be available to allow us

to successfully continue its R&D activities and planned regulatory filings with the FDA. If we are unable to obtain necessary funds,

significant reductions in spending and the delay or cancellation of planned activities may be necessary. These actions would have a material

adverse effect on our business, results of operations, and prospects. These conditions raise substantial doubt about our ability to continue

as a going concern within one year from the date this Annual Report is issued. The accompanying financial statements do not include any

adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities

that might result from the outcome of this uncertainty.

92

Contractual Obligations

We do not have any long-term

debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement to pay the Sponsor or an

affiliate of the Sponsor a monthly fee of $20,000 for office space, administrative and shared personnel support services to us. We began

incurring these fees on October 6, 2021 and incurred these fees monthly through December 31, 2022. The payment of these fees

was suspended on December 31, 2022 and reinstated on March 31, 2023. As of December 31, 2023, there was a $75,000 outstanding

balance owed to the Sponsor.

We entered into an agreement,

commencing on the date of our listing on Nasdaq, to pay the spouse of our Chief Executive Officer a monthly consulting fee of $15,000

for assisting us in identifying and evaluating potential acquisition targets. Payment of the consulting fees ended on December 31,

2022 as part of the First Charter Amendment approval.

In addition, we have an agreement

to pay the underwriter a deferred fee of $9,150,000. The deferred fee will become payable to the representative from the amounts held

in the Trust Account solely in the event that we complete a business combination, subject to the terms of the underwriting agreement.

Prior to Closing the Business Combination, we entered into a fee modification agreement with the underwriter, pursuant to which the underwriter

received shares of Common Stock in lieu of certain cash payments.

Critical Accounting Policies

The preparation of financial

statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires

management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets

and liabilities at the date of the financial statements, and income and expenses during the periods reported. Actual results could materially

differ from those estimates. We have identified the following critical accounting policies:

Accounting for Warrants

We account for Warrants as

either equity-classified or liability-classified instruments based on an assessment of the instruments’ specific terms and applicable

authoritative guidance in ASC 480 and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the instruments

are free standing financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the instruments

meet all of the requirements for equity classification under ASC 815, including whether the instruments are indexed to our own Common

Stock and whether the instrument holders could potentially require “net cash settlement” in a circumstance outside of our

control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, was conducted

at the time of warrant issuance and as of each subsequent period end date while the instruments are outstanding. Management has concluded

that the Private Warrants and Private Placement Warrants issued pursuant to the warrant agreement qualify for equity accounting treatment.

Common Stock Subject to Possible Redemption

We account for our Common

Stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.”

Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable

common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption

upon the occurrence of uncertain events not solely within our control) is classified as temporary equity. At all other times, common stock

is classified as stockholders’ equity. Our Common Stock features certain redemption rights that are considered to be outside of

our control and subject to occurrence of uncertain future events. Accordingly, Common Stock subject to possible redemption is presented

as temporary equity, outside of the stockholders’ deficit section of our balance sheets. We recognize changes in redemption value

immediately as they occur and adjust the carrying value of redeemable common stock to equal the redemption value at the end of each reporting

period. Increases or decreases in the carrying amount of redeemable common stock are affected by charges against additional paid in capital

and accumulated deficit.

Net Loss per Common Share

Net loss per share is computed

by dividing net loss by the weighted average number of shares of common stock outstanding during the period. At December 31, 2023, we did not have any dilutive securities and/or other contracts that

could, potentially, be exercised or converted into shares of common stock and then share in our earnings. As a result, diluted net loss

per share is the same as basic net loss per share for the period presented.

93

Recent Accounting Standards

In December 2023,

the Financial Accounting Standard Board (“FASB”) FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income

Tax Disclosures (“ASU 2023-09”), which requires disclosure of incremental income tax information within the rate reconciliation

and expanded disclosures of income taxes paid, among other disclosure requirements. ASU 2023-09 is effective for fiscal years beginning

after December 15, 2024. Early adoption is permitted. Management does not believe the adoption of ASU 2023-09 will have a material impact

on its consolidated financial statements and disclosures.

In June 2016, the FASB issued Accounting Standards Update (“ASU

2016-13”) Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

(“ASU 2016-13”). This update requires financial assets measured at amortized cost basis to be presented at the net amount

expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical

experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Since

June 2016, the FASB issued clarifying updates to the new standard including changing the effective date for smaller reporting companies.

The guidance is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with

early adoption permitted. We adopted ASU 2016-13 on January 1, 2023. The adoption of ASU 2016-13 did not have an impact

on our financial statements.

Management does not believe

that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying

financial statements.

Item 7A. Quantitative and Qualitative

Disclosures About Market Risk.

We are a smaller reporting company as defined

by Rule 12b-2 of the Securities Exchange Act of 1934 and are not required to provide the information under this item.

Item 8. Financial Statements and Supplementary

Data.

Our consolidated financial statements for the

year ended December 31, 2023, together with the reports of our independent registered public accounting firm, appear beginning on page

F-1 of this Annual Report.

Item 9. Changes in and Disagreements with Accountants on Accounting

and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

(a) Evaluation of Disclosure Controls and Procedures

Disclosure controls are procedures

that are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act

is recorded, processed, summarized, and reported within the time period specified in the SEC’s rules and forms. Disclosure controls

are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including the

Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

As required by Rules 13a-15

and 15d-15 under the Exchange Act, our Chief Executive Officer and Chief Financial Officer carried out an evaluation of the effectiveness

of the design and operation of our disclosure controls and procedures as of December 31, 2023. Based upon their evaluation, our Chief

Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and

15d-15(e) under the Exchange Act) were effective.

94

(b) Management’s Report on Internal Control

over Financial Reporting

As required by SEC rules

and regulations implementing Section 404 of the Sarbanes-Oxley Act, our management is responsible for establishing and maintaining

adequate internal control over financial reporting. Our internal control over financial reporting is designed to provide reasonable assurance

regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external reporting purposes

in accordance with the accounting principles generally accepted in the United States of America (“GAAP”). Our internal control

over financial reporting includes those policies and procedures that:

(1) pertain to the maintenance

of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of our company;

(2) provide reasonable assurance

that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with GAAP, and that

our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

(3) provide reasonable assurance

regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect

on the consolidated financial statements.

In the Form 10-Q for each

of the three quarters in 2023, we discovered an error in the cash flow statement for the presentation of restricted cash. Due to this

error a significant deficiency in internal controls was identified. To correct this, we have revised our cash flow statement for the December

31, 2023 audited financial statements. These errors had no impact on the balance sheets or statements of operations in those periods.

Because of its inherent limitations,

internal control over financial reporting may not prevent or detect errors or misstatements in our consolidated financial statements.

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because

of changes in conditions, or that the degree or compliance with the policies or procedures may deteriorate. Management assessed the effectiveness

of our internal control over financial reporting at December 31, 2023. In making these assessments, management used the criteria

set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control — Integrated

Framework (2013). Based on our assessments and those criteria, management determined that, except for the significant deficiency described

above, we maintained effective internal control over financial reporting as of December 31, 2023.

This Annual Report does not

include an attestation report of our independent registered public accounting firm due to our status as an emerging growth company under

the JOBS Act.

(c) Changes in Internal Control over Financial

Reporting

There were no changes in

our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during

the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over

financial reporting. The assessment of our disclosure controls and internal control over financial reporting was conducted as of December

31, 2023 with respect to PBAX and does not reflect any changes resulting from the subsequent consummation of the Business Combination.

(d) Inherent Limitations on Effectiveness of

Controls

Our

disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of

achieving the desired control objectives. Our management recognizes that any controls and procedures, no matter how well designed and

operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating

the cost-benefit relationship of possible controls and procedures. Similarly, an evaluation of controls cannot provide absolute assurance

that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

Item 9B. Other Information.

(a) On April 1, 2024, we consummated a private placement of 626 shares

of Series B Preferred Stock, pursuant to the Securities Purchase Agreement, dated March 28, 2024, by and among us and certain accredited

investors (the “Additional Investors” and, together with the Initial Investors, the “PIPE Investors”), for aggregate

cash proceeds to us of approximately $0.5 million.

(b) During the three-month

period ended December 31, 2023, none of our directors or officers (as defined in Rule 16a-1(f) of the Securities Exchange Act of 1934,

as amended) adopted, terminated or modified a Rule 10b5-1 trading arrangement or any “non-Rule 10b5-1 trading agreement” (as

defined in Item 408(c) of Regulation S-K).

Item 9C. Disclosure Regarding Foreign

Jurisdictions that Prevent Inspections.

Not applicable.

Family Relationships

There are no family relationships

between our board of directors and any of our executive officers.

98

Board of Directors

Director Independence

Nasdaq listing rules require

that a majority of the board of directors of a company listed on Nasdaq be composed of “independent directors,” which is defined

generally as a person other than an officer or employee of a company or its subsidiaries or any other individual having a relationship,

which, in the opinion of such company’s board of directors, would interfere with the director’s exercise of independent judgment

in carrying out the responsibilities of a director. Based on business and personal information provided

by each director concerning her or his background, employment, and affiliations, including family relationships, our board of directors

has determined that each of Mr. Byrnes, Mr. Ehrlich, Ms. LaPorte, Ms. Rapaport and Dr. Rolfe is an independent director under the Nasdaq

listing rules and Rule 10A-3 of the Exchange Act. In addition, we determined that each of Brian G. Atwood, Barbara A. Kosacz and

Caroline M. Loewy, who served on the board of directors during fiscal year 2023, was also an independent director under the Nasdaq

listing rules and Rule 10A-3 of the Exchange Act; provided, however, that in connection with Mr. Atwood’s appointment as our Chief

Executive Officer at the Closing, Mr. Atwood is no longer independent.

In

addition, the rules of Nasdaq require that, subject to specified exceptions, each member of a listed company’s audit, compensation

and nominating and corporate governance committees be independent. Under the rules of Nasdaq, a director will only qualify as an “independent

director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere

with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations,

our board of directors considered the current and prior relationships that each non-employee director has with us and all other facts

and circumstances our board of directors deemed relevant in determining independence, including the beneficial ownership of our Common

Stock by each non-employee director and relationships with each of PBAX and Legacy CERo.

Classified Board of Directors

In accordance with the terms

of our Charter, our board of directors is divided into three classes with staggered, three-year terms. At each annual meeting of stockholders,

the directors whose terms then expire will be eligible for reelection until the third annual meeting following reelection. Our directors

are divided among the three classes as follows:

Our Bylaws provide that the

number of members of our board of directors shall be fixed in accordance with our Charter. Our Charter provides that the authorized number

of directors may be changed only by resolution of the board of directors. Any additional directorships resulting from an increase in the

number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of

the directors. Our board of directors is currently fixed at seven members. The division of our board of directors into three classes with

staggered three-year terms may delay or prevent a change of our board of directors or a change in control of our company. Our directors

may be removed only for cause by the affirmative vote of the holders of at least two-thirds of our outstanding voting stock then entitled

to vote in an election of directors.

Director Attendance at Annual Meeting of

Stockholders

We encourage our directors

to attend our annual meetings of stockholders. We did not hold an annual meeting of stockholders during the fiscal year ended December

31, 2023.

99

Board and Committee Meetings

During the fiscal year

ended December 31, 2023, our board of directors met four times, our Audit Committee met four times, our Compensation Committee

and our nominating and corporate governance committee met zero times.

Each board member attended 75% or more of the aggregate number of meetings of the board of directors and meetings of the committees

on which he or she served during the fiscal year ended December 31, 2023, for which he or she was a director or committee

member.

Board Leadership Structure

Our board of directors does

not have a policy regarding separation of the roles of Chief Executive Officer and chairman of the board of directors. Our board of directors

recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as

we continue to grow, and believes it is in our best interests to make determinations regarding such leadership structure based on circumstances

from time to time. Currently, our Chief Executive Officer serves as the chairman of the board of directors.

Our board of directors believe

that this leadership structure, combined with our corporate governance policies and processes, creates an appropriate balance between

strong and consistent leadership and independent oversight of our business. The chairman chairs the meetings of our board of directors

and stockholders, with input from the independent directors, and as such, our board of directors believes that a person with comprehensive

knowledge of our company is in the best position to serve such role. In making this determination, the board of directors considered,

among other matters, Mr. Atwood’s management of our business on a day-to-day basis coupled with his direct involvement in our business

operations, and believed that Mr. Atwood is highly qualified to act as both chairman and Chief Executive Officer due to his experience,

knowledge and history with both Legacy CERo and PBAX.

In addition, each of our

other directors is “independent” under Nasdaq standards. Our independent vice chairman presides over regularly-held executive

sessions of independent directors, without management present, and all of our independent directors are active in the oversight of our

company. In addition, our board of directors and each committee of board of directors has complete and open access to any member of management

and the authority to retain independent legal, financial and other advisors as they deem appropriate.

Our board of directors believe

its administration of its risk oversight function has not affected its leadership structure. Risk is inherent with every business, and

how well a business manages risk can ultimately determine its success. Our board of directors is actively involved in oversight of risks

that could affect us. This oversight is conducted primarily by our full board of directors, which has responsibility for general oversight

of risks, and the Audit Committee, which has responsibility for reviewing the adequacy of our risk management activities with management

and our independent registered public accounting firm.

At each of its meetings,

the board of directors receives business updates from various members of management. These updates may identify matters that have emerged

within that member of management’s scope of responsibility that involve operational, financial, legal or regulatory risks and, in

these cases, the board of directors provides guidance to management. Our board of directors believes that full and open communication

between management and the board of directors is essential for effective risk management and oversight.

Our board of directors has

concluded that our current leadership structure is appropriate at this time. However, our board of directors will continue to periodically

review our leadership structure and may make such changes in the future as it deems appropriate.

Role of Board in Risk Oversight

Our board of directors has

responsibility for the oversight of our risk management processes and, either as a whole or through its committees, regularly discusses

with management our major risk exposures, their potential impact on our business and the steps we take to manage them. The risk oversight

process includes receiving regular reports from board committees and members of senior management to enable our board of directors to

understand our risk identification, risk management and risk mitigation strategies with respect to areas of potential material risk, including

operations, finance, legal, regulatory, strategic and reputational risk.

100

The Audit Committee reviews

information regarding liquidity and operations, and oversees our management of financial risks. It also reviews information and policies

related to information technology risk, including cyber-security and incident response planning. Periodically, the Audit Committee reviews

our policies with respect to risk assessment, risk management, loss prevention and regulatory compliance. Oversight by the Audit Committee

includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the

actions management has taken to limit, monitor or control such exposures. The Compensation Committee is responsible for assessing whether

any of our compensation policies or programs has the potential to encourage excessive risk-taking. The nominating and corporate governance

committee manages risks associated with the independence of the board of directors, corporate disclosure practices and potential conflicts

of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire

board of directors is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered

by our board of directors as a whole.

Committees of the Board of Directors

The standing committees of

our board of directors include the Audit Committee, a Compensation Committee, and a nominating and corporate governance committee, each

of which operates under a charter that has been approved by our board of directors. Such charters are available on our website at www.cero.bio/investors.

The reference to our website address does not constitute incorporation by reference of the information contained at or available through

our website. We have included our website address as an inactive textual reference only.

Committee are Mr. Byrnes, Mr. Ehrlich, and Ms. Rapaport. Mr. Byrnes serves as the chairperson of the Audit Committee. All members of our

each of Mr. Byrnes, Mr. Ehrlich and Ms. Rapaport is independent under the applicable rules of the SEC and Nasdaq and has

arriving at this determination, our board of directors has examined each Audit Committee

member’s scope of experience and the nature of their experience reading and understanding financial statements.
