 • On the cover page, (i) to delete the reference in the Original Form 10-K to the incorporation by reference of the Company's definitive proxy statement for its 2024 annual meeting of stockholders (the "Annual Meeting") and (ii) to update the date as of which the number of outstanding shares of the Company's common stock is being provided;

 Corporate Governance

 General

 Our Board has adopted a Code of Business Conduct and Ethics, and charters for our Nominating and Corporate Governance Committee, Audit Committee and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters and our Code of Business Conduct and Ethics in the "Governance" section under "Governance Documents" of our investor relations page of our website located at investors.seastarmedical.com, or by writing to c/o Corporate Secretary at our offices at 3513 Brighton Blvd, Suite 410, Denver, CO 80216.

 Board Composition

 Our Board currently consists of seven members: Rick Barnett; Allan Collins, MD; Andres Lobo; Bruce Rodgers; Richard Russell; Eric Schlorff; and Kenneth Van Heel. As set forth in our Charter, the Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our Charter provides that the authorized number of directors may be fixed from time to time by the Board, except as otherwise provided for or fixed relating to the rights of the holders of any series of Preferred Stock to elect additional 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. The division of our Board into three classes with staggered three-year terms may delay or prevent a change of our management 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 the total voting power of the outstanding shares of our capital stock entitled to vote in the election of directors.

 Independence of the Board

 As required under Nasdaq listing standards, a majority of the members of a listed company's Board must qualify as "independent," as affirmatively determined by the Board. The Board consults with the Company's counsel to ensure that the Board's determinations are consistent with relevant securities and other laws and regulations regarding the definition of "independence," including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

 Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that the following six directors, representing a majority of the members of the Board, are independent directors within the meaning of the applicable Nasdaq listing standards: Mr. Barnett, Dr. Collins, Mr. Lobo, Mr. Van Heel, Mr. Rodgers and Mr. Russell. In making this determination, the Board found that none of these directors had a material or other disqualifying relationship with the Company. As Mr. Schlorff serves as our Chief Executive Officer, he is not independent. Additionally, in accordance with our Corporate Governance Guidelines, the Board determined that all members of the audit, compensation, and nominating and corporate governance committees of the Board are independent.

 Director Candidates

 The Nominating and Corporate Governance Committee is primarily responsible for searching for qualified director candidates for election to the Board and filling vacancies on the Board. To facilitate the search process, the Nominating and Corporate Governance Committee may solicit current directors and executives of the Company for the names of potentially qualified candidates or ask directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates or consider director candidates recommended by our stockholders. Once potential candidates are

 identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates' independence from the Company and potential conflicts of interest and determines if candidates meet the qualifications desired by the Nominating and Corporate Governance Committee for candidates for election as a director.

 In evaluating the suitability of individual candidates (both new candidates and current Board members), the Nominating and Corporate Governance Committee, in recommending candidates to the Board, and the Board, in approving and recommending for election (and, in the case of vacancies, appointing) such candidates, will consider candidates who have a high level of personal and professional integrity, strong ethics and values and the ability to make mature business judgments. In evaluating director candidates, the Nominating and Corporate Governance Committee and the Board may also consider the following criteria as well as any other factor that they may deem to be relevant: the candidate's experience in corporate management, such as serving as an officer or former officer of a publicly held company; the candidate's experience as a board member of another publicly held company; the candidate's professional and academic experience relevant to the Company's industry; the strength of the candidate's leadership skills; the candidate's experience in finance and accounting and / or executive compensation practices; and whether the candidate has the time required for preparation, participation and attendance at Board meetings and committee meetings, if applicable. In addition, the Board will consider whether there are potential conflicts of interest with the candidate's other personal and professional pursuits. In addition, the Board monitors the mix of specific experience, qualifications and skills of its directors in order to assure that the Board, as a whole, has the necessary tools to perform its oversight function effectively in light of the Company's business and structure. Although the Board does not have a formal written diversity policy with respect to the evaluation of director candidates, in its evaluation of director candidates, the Nominating and Corporate Governance Committee will consider factors including, without limitation, issues of judgment, diversity, age, skills, background and experience, and with respect to diversity, such factors as gender, race, ethnicity, experience, and area of expertise, as well as other individual qualities and attributes that contribute to the total diversity of viewpoints and experience represented on the Board.

 Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials as set forth in our Bylaws, to the Nominating and Corporate Governance Committee, c/o Corporate Secretary, SeaStar Medical Holding Corporation, 3513 Brighton Blvd, Suite 410, Denver, CO 80216. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates recommended by other sources.

 Communications from Interested Parties

 Anyone who would like to communicate with, or otherwise make his or her concerns known directly to the chairperson of any of the Audit, Nominating and Corporate Governance, and Compensation Committees, or to the non-management or independent directors as a group, may do so by addressing such communications or concerns to c/o Corporate Secretary, SeaStar Medical Holding Corporation, 3513 Brighton Blvd, Suite 410, Denver, CO 80216, which will forward such communications to the appropriate party. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

 Board Leadership Structure

 The Board has not implemented a policy requiring the positions of the Chairman of the Board and Chief Executive Officer to be separate or held by the same individual. Any further determination to create such a policy is expected to be based on circumstances existing from time to time, based on criteria that are in the Company's best interests and the best interests of its stockholders, including the composition, skills and experience of the Board and its members, specific challenges faced by the Company or the industry in which we operate, and governance efficiency. Mr. Barnett serves as the Chairman of the Board. The Board believes that

 having an independent director serving as the Chairman provides better and effective oversight and management of the Company as a publicly traded company, which also improves management efficiency as the Chief Executive Officer can focus on day-to-day operations of the Company. If the Board convenes for a meeting, the non-management directors will meet in one or more executive sessions, if the circumstances warrant it. The Board may also consider appointing a lead independent director, if the circumstances warrant it.

 Risk Oversight

 The Board will administer the risk oversight function directly through the Board as a whole, as well as through its committees, where applicable, monitoring and assessing strategic risk exposure, enterprise risk, and governance risks. The audit committee will be responsible for considering and discussing our major financial risk exposures and the steps our management has taken to monitor and control these exposures. The compensation committee is responsible for reviewing and assessing the risks associated with the compensation arrangements of executive management, including the lack of alignment between the incentives of management and the interests of stockholders. The allocation of risk oversight responsibility may change, from time to time, based on the evolving needs of the Company.

 Executive Sessions of Non-Management Directors

 As provided in the Corporate Governance Guidelines, the non-management directors meet, without management directors or management present on a regularly scheduled basis. If the non-management directors include directors who are not considered independent, the independent directors must also meet in executive session the conclusion of each board meeting. Our Chairman of the Board, Rick Barnett currently presides over executive sessions.

 Code of Business Conduct and Ethics

 We have adopted a Code of Business Conduct and Ethics applicable to our directors, executive officers and employees. The Code of Business Conduct and Ethics is available on our website at www.investors.seastarmedical.com/governance/governance-documents. The Company will disclose any amendments to, or waivers of, provisions of our Code of Business Conduct and Ethics on our website.

 Anti-Hedging Policy

 Our Board has adopted an Insider Trading Policy, which applies to all of our directors, officers and employees. The policy prohibits our employees and directors from engaging in any hedging transactions (including transactions involving options, puts, calls, prepaid variable forward contracts, equity swaps, collars and exchange funds or other derivatives) that are designed to hedge or speculate on any change in the market value of the Company's equity securities.

 Attendance by Members of the Board at Meetings

 As of December 31, 2023, the Board held 6 meetings of the Board. During the fiscal year ended December 31, 2023, except for Mr. Rodgers and Mr. Russell, each director attended at least 75% of the aggregate of (i) all meetings of the Board and (ii) all meetings of the committees on which the director served during the period in which he or she served as a director.

 Each director is expected to spend the time and effort necessary to properly discharge his or her responsibilities. Accordingly, a director is expected to attend all meetings of the Board and meetings of the committees on which the director sits (including separate meetings of the independent directors), with the understanding that, on occasion, a director may be unable to attend a meeting. We do not maintain a formal policy regarding director attendance at our annual meetings; however, we encourage our directors to attend each annual meeting.

 Audit Committee

 Our Audit Committee will be responsible for, among other things:

 • retaining, overseeing and evaluating the independence and performance of our independent auditor;

 • reviewing and discussing with our independent auditor their annual audit, including the timing and scope of audit activities;

 • pre-approving audit services;

 • overseeing the financial reporting process and discussing with management and our independent registered public accounting firm the quarterly and annual financial statements that we file with the SEC;

 • reviewing the adequacy and effectiveness of our accounting and internal controls over financial reporting, disclosure controls and policies and procedures;

 • reviewing and discussing guidelines and policies governing the process by which our senior management assesses and manages our exposure to risk;

 • reviewing, and if appropriate, approving or ratifying any related party transactions and other significant conflicts of interest;

 • establishing procedures for the receipt, retention and treatment of complaints received by us and the confidential, anonymous submission by our employees of concerns regarding questionable accounting or auditing matters;

 • reviewing our program to monitor compliance with our code of ethics; and

 • overseeing significant deficiencies and material weaknesses in the design or operation of our internal controls over financial reporting.

 Our Audit Committee currently consists of Rick Barnett and Allan Collins, MD, and Kenneth Van Heel, with Mr. Van Heel serving as chair of the Audit Committee. Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Nasdaq rules require that our audit committee must be composed entirely of independent members. Each of Rick Barnett, Allan Collins, MD, and Kenneth Van Heel meet the definition of "independent director" for purposes of serving on the audit committee under Rule 10A-3 of the Exchange Act and Nasdaq rules. Each member of our audit committee also meets the financial literacy requirements of the Nasdaq listing standards. In addition, the Board determined that Kenneth Van Heel qualifies as an "audit committee financial expert," as such term is defined in Item 407(d)(5) of Regulation S-K.

 Compensation Committee

 Our Compensation Committee is responsible for, among other things:

 • reviewing and approving the compensation of our executive officers;

 • reviewing and recommending to our Board the compensation of our directors;

 • reviewing and recommending to our Board the compensation of our directors;

 • overseeing the development and implementation of compensation plan programs;

 • establishing and administering our incentive compensation and equity-based plans and approving or recommending to our Board for approval amendments to these plans if deemed appropriate;

 • reviewing and approving any severance or termination arrangements to be made with any of our executive officers; and

 • reviewing and approving at least annually the corporate goals and objectives relevant to the compensation of our Chief Executive Officer and other executive officers.

 Our Compensation Committee currently consists of Allan Collins, Rick Barnett, and Richard Russell, with Mr. Barnett serving as the chair of the Compensation Committee. Each member of the committee is a

 non-employee director, as defined in Rule 16b-3 promulgated under the Exchange Act. Following the completion of the Annual Meeting, we expect Allan Collins and Rick Barnett to continue to serve as members of the Compensation Committee, with Mr. Barnett serving as the chair of the Compensation Committee, and we expect to appoint another independent director to the Compensation Committee.

 Nominating and Corporate Governance Committee

 Our Nominating and Corporate Governance Committee will be responsible for, among other things:

 • identifying, screening and recommending to our Board director candidates for election (or re-election);

 • overseeing the policies and procedures with respect to the consideration of director candidates recommended by stockholders;

 • reviewing and recommending to our Board for approval, as appropriate, disclosures concerning our policies and procedures for identifying and screening Board nominee candidates, the criteria used to evaluate Board membership and director independence as well as any policies regarding Board diversity;

 • reviewing independence qualifications of directors under the applicable Nasdaq rules;

 • developing and coordinating with management on appropriate director orientation programs; and

 • our stockholder engagement plan, if any, and overseeing relations with stockholders.

 Our Nominating and Corporate Governance Committee currently consists of Andres Lobo, Bruce Rodgers, and Kenneth Van Heel, with Mr. Rodgers serving as the chair of the Nominating and Corporate Governance Committee. Following the completion of the Annual Meeting, we expect Andres Lobo, Richard Barnett, and Kenneth Van Heel to serve as the Nominating and Corporate Governance Committee, with Mr. Barnett serving as the chair of the Nominating and Corporate Governance Committee, and we expect to appoint another independent director to the Nominating and Corporate Governance Committee.

 Board Leadership Structure

 The Board has not implemented a policy requiring the positions of the Chairman of the Board and Chief Executive Officer to be separate or held by the same individual. Any further determination to create such a policy is expected to be based on circumstances existing from time to time, based on criteria that are in the Company's best interests and the best interests of its stockholders, including the composition, skills and experience of the Board and its members, specific challenges faced by the Company or the industry in which we operate, and governance efficiency. Historically Mr. Schlorff served as both the Chairman and Chief Executive Officer because Mr. Schlorff's strategic vision for the business, his in-depth knowledge of the Company's operations, and his experience serving as the Chief Executive Officer of SeaStar Medical make him well qualified to serve as both Chairman of the Board and Chief Executive Officer of the Company. However, effective as of the Closing, the Board determined that it is in the best interest of the Company and its stockholders to separate the roles of Chairman and Chief Executive Officer and elected Mr. Barnett as the Chairman of the Board. The Board believes that having an independent director serving as the Chairman provides better and effective oversight and management of the Company as a publicly traded company, which also improves management efficiency as the Chief Executive Officer can focus on day-to-day operations of the Company. If the Board convenes for a meeting, the non-management directors will meet in one or more executive sessions, if the circumstances warrant it. The Board may also consider appointing a lead independent director, if the circumstances warrant it. In addition, the Board has granted Dr. David Humes, previously a director of SeaStar Medical, certain rights to attend regularly scheduled meetings of the Board as an observer without any voting or other substantive rights provided to directors.

 Risk Oversight

 The Board will administer the risk oversight function directly through the Board as a whole, as well as through its committees, where applicable, monitoring and assessing strategic risk exposure, enterprise risk, and governance risks. The audit committee will be responsible for considering and discussing our major financial risk exposures and the steps our management has taken to monitor and control these exposures. The compensation committee will be responsible for reviewing and assessing the risks associated with the compensation arrangements of executive management, including the lack of alignment between the incentives of management and the interests of stockholders. The allocation of risk oversight responsibility may change, from time to time, based on the evolving needs of the Company.

 Delinquent Section 16(a) Reports

 Section 16(a) of the Exchange Act requires the Company's directors and executive officers, and persons who own more than ten percent of a registered class of the Company's equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of common stock and other equity securities of the Company. Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file.

 To our knowledge, based solely on our review of such reports filed on EDGAR and the written representations of reporting persons, we believe that for the year ended December 31, 2023, all required reports were filed on a timely basis under Section 16(a).

 Item 11. Executive Compensation.

 Overview

 This section discusses the material components of the executive compensation program for SeaStar Medical's executive officers who are named below. As an emerging growth company, we have opted to comply with the executive compensation disclosure rules applicable to "smaller reporting companies" as such term is defined in the rules promulgated under the Securities Act, which require compensation disclosure for our principal executive officer and our two other most highly compensated executive officers.

 In 2023, SeaStar Medical's chief executive officer and its two other executive officers, referred to collectively as SeaStar Medical's "named executive officers," were as follows:

 • Eric Schlorff, Chief Executive Officer

 • Caryl Baron, Interim Chief Financial Officer(*)

 • Kevin Chung, MD, Chief Medical Officer

 * Ms. Baron transitioned into the role of Vice President of Finance of the Company effective January 10, 2024, and her employment was terminated effective April 23, 2024.

 2023 Compensation of Named Executive Officers

 Base Salary

 Base salaries are intended to provide a level of compensation sufficient to attract and retain an effective management team, when considered in combination with the other components of the executive compensation program. In general, SeaStar Medical seeks to provide a base salary level designed to reflect each executive officer's scope of responsibility and accountability. As a result of the financial constraints on the Company's cash during 2023, a portion of the base salaries for our executive officers and other employees was paid in shares of our Common Stock. Please see the "Salary" column in the "Summary Compensation Table for Fiscal Years 2023 and 2022" below for the base salary amounts received by the named executive officers in fiscal 2022 and 2023.

 Long-Term Equity Incentive Awards

 To further focus SeaStar Medical's named executive officers on its long-term performance, SeaStar Medical may grant equity compensation in the form of stock options and restricted stock units. Restricted stock units were granted to Mr. Schlorff and Ms. Baron in 2023. For more information, see "Summary Compensation Table for Fiscal Years 2023 and 2022," "Outstanding Equity Awards at December 31, 2023," and "Employee Benefit and Equity Compensation Plans" below.

 Incentive Compensation

 SeaStar Medical periodically uses bonuses to incentivize and retain its employees, including its named executive officers. Please see the "Bonus" column in the "Summary Compensation Table for Fiscal Years 2022 and 2023" below for the bonus amounts received by the named executive officers in fiscal 2023.

 SeaStar Medical periodically enters into agreements to grant short- and long-term cash or stock incentive awards to its employees including its named executive officers to encourage achievement of certain performance goals. This includes incentive awards based on the achievement of certain business development, financing milestone, and exit event goals. In addition, SeaStar Medical periodically awards its named executive officers annual bonuses from a discretionary bonus pool. However, no such incentive awards were granted by SeaStar Medical's named executive officers during fiscal 2023.

 In April 2023, Ms. Baron was granted $30,000 worth of shares in Company Common Stock as a bonus for her service as the Interim Chief Financial Officer in 2023.

The grant date fair value was determined using the closing share price of the Corporation's common stock on the date of grant. For information regarding assumptions underlying the valuation of equity awards, see Notes 2 and 12. to SeaStar Medical's audited financial statements appearing in the 2023 Annual Report. The restricted stock units granted in 2023 have a one-year vesting period and became fully vested on April 6, 2024.

For information regarding assumptions underlying the valuation of equity awards, see Notes 2 and 12 to SeaStar Medical's audited financial statements appearing in the 2023 Annual Report. These options have a one-year vesting period and became fully vested on April 6, 2024.

 (4) Amounts reflect the exit event bonus that was earned in connection with the Business Combination under the terms of the transaction bonus agreements. See "Narrative to Summary Compensation Table - Cash Incentive Compensation".

 Compensation Recovery Policy

 On December, 1, 2023, the Compensation Committee adopted a compensation clawback policy (the "Clawback Policy") in compliance with the final rules promulgated by the SEC under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, Rule 10D-1 and Nasdaq (together, the "Clawback Rules") that provides for the recovery of certain incentive-based compensation in the event we are required to restate our financial statements. The Clawback Policy provides that, in the event of the restatement of any financial reporting required under the securities laws or other similar laws or regulations, our board of directors (or applicable committee thereof) will take such actions as necessary to recover the portion of any incentive-based compensation that was granted, earned or vested based wholly or in part on the attainment of a financial reporting measure which was received by the executive officer that was in excess of the amount that he or she would have received had our financial results been calculated under the restated financial statements; provided that such compensation was paid to or awarded to the executive officer, or which vested (or became eligible to vest) during the Clawback Period. "Clawback Period" under the Clawback Policy is defined as the three completed fiscal years immediately prior to the date on which our board of directors or management determine we are required to (or we are otherwise legally directed to) prepare an accounting restatement and any transition period between the last day of our previous fiscal year end and the first day of our new fiscal year (that results from a change in our fiscal year) within or immediately following such three-year period; provided that any transition period between the last day of our previous fiscal year end and the first day of its new fiscal year that comprises a period of nine to 12 months will be deemed a completed fiscal year.

 As disclosed in the 2023 Annual Report, certain of our previously filed interim unaudited and annual audited consolidated financial statements should no longer be relied upon and we therefore restated in the 2023 Annual Report (i) our consolidated financial statements as of and for the year ended December 31, 2022 and (ii) our unaudited quarterly financial data for the first three quarters of the year ended December 31, 2023. However, because we did not award to any of our executive officers any incentive-based compensation during the fiscal years ended December 31, 2023, 2022 and 2021 that was granted, earned, vested or eligible to vest based wholly or in part on the attainment of a financial reporting measure, we concluded that no recovery of erroneously awarded compensation was required pursuant to our Clawback Policy and the Clawback Rules.

 Employee Benefit and Equity Compensation Plans

 The principal features of SeaStar Medical's existing employee benefit and equity incentive plans are summarized below.

 Equity Incentive Plans

 SeaStar Medical, Inc. 2019 Stock Incentive Plan

 In connection with the Business Combination, the Company assumed all outstanding awards under the SeaStar Medical, Inc. 2019 Stock Incentive Plan, consisting of 244,792 options, and 289,389 restricted stock units. The awards that were outstanding as of December 31, 2023, are included in the "Outstanding Equity Awards at December 31, 2023" table above. No further grants will be made under that plan.

 2022 Omnibus Incentive Plan

 The 2022 Omnibus Incentive Plan was originally adopted by our Board on August 22, 2022, was approved by our stockholders as of October 18, 2022, and was subsequently amended and approved by our stockholders effective as of September 6, 2023, and replaced the existing 2019 Stock Incentive Plan.

 General Provisions

 Change in Control

 In the event we should experience a change in control, the following provisions are in effect for all outstanding awards under the Plan, unless provided otherwise in an award agreement entered into with the participant:

 • Each outstanding award may be assumed, substituted, replaced with a cash retention program that preserves the intrinsic value of the award and provides for subsequent payout in accordance with the same vesting schedule applicable to the award or otherwise continued in effect by the successor corporation.

 • To the extent an award is not so assumed, substituted, replaced, or continued, the award will automatically accelerate in full (with vesting of performance-based awards to be determined with reference to actual performance attained as of the change in control or based on target level), unless the acceleration of such award is precluded by other limitations imposed in the applicable award agreement.

 • The plan administrator has complete discretion to grant one or more awards which will vest in the event the individual's service with us or the successor entity is terminated within a designated period following a change in control transaction in which those awards are assumed or otherwise continued in effect.

 • Unless the plan administrator establishes a different definition for one or more awards, a change in control will be deemed to occur for purposes of the Plan in the event (a) a merger or asset sale or (b) there occurs any transaction pursuant to which any person or group of related persons becomes directly or indirectly the beneficial owner of securities possessing 50% or more of the total combined voting power of our outstanding securities or (c) there is a change in the majority of the Board effected through one or more contested elections for board membership.

 Changes in Capitalization

 In the event any change is made to the outstanding Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares, spin-off transaction, or other change affecting the outstanding Common Stock without our receipt of consideration or should the value of our outstanding Common Stock be substantially reduced by reason of a spin-off transaction or extraordinary distribution (whether in cash, securities or other property) or an extraordinary distribution, or should there occur any merger, consolidation, reincorporation or other reorganization, equitable adjustments will be made to: (i) the maximum number and/or class of securities issuable under the Plan; (ii) the maximum number and/or class of securities for which incentive options may be granted under the Plan; (iii) the maximum number and/or class of securities for which any one person may be granted awards under the Plan per calendar year; (iv) the number and/or class of securities and the exercise price per share in effect for outstanding award and the cash consideration (if any) payable per share; (v) the number and/or class of securities subject to repurchase rights under the Plan and the repurchase price payable per share; and (vi) such other terms and conditions as the plan administrator deems appropriate. Such adjustments will be made in such manner as the plan administrator deems appropriate.

 Valuation

 The fair market value per share of Common Stock on any relevant date under the Plan is deemed to be equal to the closing selling price per share on that date as determined on Nasdaq. As of April 24, 2024, the fair market value of a share of Common Stock determined on such basis was $0.5085 per share.

 Stockholder Rights and Transferability

 No optionee has any stockholder rights with respect to the option shares until such optionee has exercised the option and paid the exercise price for the purchased shares. The holder of a stock appreciation right will not have any stockholder rights with respect to the shares subject to that right unless and until such person exercises the right and becomes the holder of record of any shares of Common Stock distributed upon such exercise. Options are not assignable or transferable other than by will or the laws of inheritance following optionee's death, and during the optionee's lifetime, the option may only be exercised by the optionee. However, the plan administrator may structure one or more non-statutory options under the Plan so that those options will be transferable during optionee's lifetime to one or more members of the optionee's family or to a trust established

 for the optionee and/or one or more such family members or to the optionee's former spouse, to the extent such transfer is in connection with the optionee's estate plan or pursuant to a domestic relations order. Stand-alone stock appreciation rights will be subject to the same transferability restrictions applicable to non-statutory options.

 A participant will have full stockholder rights with respect to any shares of Common Stock issued to the participant under the Plan, whether or not the participant's interest in those shares is vested. A participant will not have any stockholder rights with respect to the shares of Common Stock subject to restricted stock units until that award vests and the shares of Common Stock are issued thereunder. However, dividend-equivalent units may be paid or credited, either in cash or in actual shares, on outstanding restricted stock units, subject to such terms and conditions as the plan administrator may deem appropriate.

 Notwithstanding the foregoing, any dividends or dividend equivalents payable in connection with an award will be subject to the same restrictions as the underlying award and will not be paid until and unless such award vests.

 Withholding Taxes

 A participant shall be required to pay to the Company, and the Company shall have the right to withhold, from any cash, shares or other securities or property issuable under any award or from any other compensation, any required withholding or any other applicable taxes or other amounts due in respect of an award. The plan administrator may provide one or more holders of awards under the Plan with the right to have us withhold a portion of the shares otherwise issuable to such individuals in satisfaction of the withholding taxes to which they become subject in connection with the issuance, exercise, or settlement of those awards. Alternatively, the plan administrator may allow such individuals to deliver previously acquired shares of Common Stock in payment of such withholding tax liability.

 Deferral Programs

 The plan administrator may structure one or more awards (other than options and stock appreciation rights) so that the participants may be provided with an election to defer the compensation associated with those awards for federal income tax purposes.

 The plan administrator may also implement a non-employee director retainer fee deferral program that allows the non-employee directors the opportunity to elect to convert the Board and Board committee retainer fees to be earned for a year into restricted stock units that defer the issuance of the shares of Common Stock that vest under those units until a permissible date or event under Internal Revenue Code Section 409A.

 To the extent we maintain one or more separate non-qualified deferred compensation arrangements which allow the participants the opportunity to make notional investments of their deferred account balances in shares of Common Stock, the plan administrator may authorize the share reserve under the Plan to serve as the source of any shares of Common Stock that become payable under those deferred compensation arrangements.

 Clawback / Forfeiture

 All awards shall be subject to any clawback, recoupment or other similar policy adopted by the Board, and any cash, shares of Common Stock or other property or amounts due, paid, or issued to a participant shall be subject to the terms of such policy.

 Amendment and Termination

 Our Board may amend or modify the Plan at any time subject to stockholder approval to the extent required under applicable law or regulation or pursuant to the listing standards of the stock exchange on which our shares are at the time primarily traded. Unless sooner terminated by our Board, the Plan will terminate on the earliest of (i) the date immediately preceding the tenth anniversary of the Plan Effective Date, (ii) the date on which all shares available for issuance under the Plan have been issued as fully-vested shares or (iii) the termination of all outstanding awards in connection with certain changes in control or ownership.

 Summary of U.S. Federal Income Tax Consequences

 The following is a summary of the U.S. federal income taxation treatment applicable to us and the participants who receive awards under the Plan.

 Option Grants

 Options granted under the Plan may be either incentive options, which satisfy the requirements of Section 422 of the Code, or non-statutory options, which are not intended to meet such requirements. The federal income tax treatment for the two types of options differs as follows:

 Incentive Options

 No taxable income is recognized by the optionee at the time of the option grant, and no taxable income is recognized for regular tax purposes at the time the option is exercised, although taxable income may arise at that time for alternative minimum tax purposes. The optionee will recognize taxable income in the year in which the purchased shares are sold or otherwise made the subject of certain other dispositions. For Federal tax purposes, dispositions are divided into two categories: (i) qualifying, and (ii) disqualifying. A qualifying disposition occurs if the sale or other disposition is made more than two (2) years after the date the option for the shares involved in such sale or disposition is granted and more than one (1) year after the date the option is exercised for those shares. If the sale or disposition occurs before these two periods are satisfied, then a disqualifying disposition will result.

 Upon a qualifying disposition, the optionee will recognize long-term capital gain in an amount equal to the excess of (i) the amount realized upon the sale or other disposition of the purchased shares over (ii) the exercise price paid for the shares. If there is a disqualifying disposition of the shares, then the excess of (i) the fair market value of those shares on the exercise date or (if less) the amount realized upon such sale or disposition over (ii) the exercise price paid for the shares will be taxable as ordinary income to the optionee. Any additional gain or loss recognized upon the disposition will be a capital gain or loss.

 If the optionee makes a disqualifying disposition of the purchased shares, then we will be entitled to an income tax deduction, for the taxable year in which such disposition occurs, equal to the amount of ordinary income recognized by the optionee as a result of the disposition (subject to the limitations described below). We will not be entitled to any income tax deduction if the optionee makes a qualifying disposition of the shares.

 Non-Statutory Options

 No taxable income is recognized by an optionee upon the grant of a non-statutory option. The optionee will in general recognize ordinary income, in the year in which the option is exercised, equal to the excess of the fair market value of the purchased shares on the exercise date over the exercise price paid for the shares, and the optionee will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the optionee with respect to the exercised non-statutory option (subject to the limitations described below). The deduction will in general be allowed for our taxable year in which such ordinary income is recognized by the optionee.

 Stock Appreciation Rights

 No taxable income is recognized upon receipt of a stock appreciation right. The holder will recognize ordinary income in the year in which the stock appreciation right is exercised, in an amount equal to the excess of the fair market value of the underlying shares on the exercise date over the exercise price in effect for the exercised right, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder in connection with the exercise of the stock appreciation right (subject to the limitations described below). The deduction will be allowed for the taxable year in which such ordinary income is recognized.

 Stock Awards

 The recipient of unvested shares of Common Stock issued under the Plan will not recognize any taxable income at the time those shares are issued but will have to report as ordinary income, as and when those shares subsequently vest, an amount equal to the excess of (i) the fair market value of the shares on the vesting date over (ii) the cash consideration (if any) paid for the shares. The recipient may, however, elect under Section 83(b) of the Code to include as ordinary income in the year the unvested shares of Common Stock are issued an amount equal to the excess of (i) the fair market value of those shares on the issue date over (ii) the cash consideration (if any) paid for such shares. If the Section 83(b) election is made, the recipient will not recognize any additional income as and when the shares subsequently vest. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the recipient with respect to the unvested shares (subject

 to the limitations described below). The deduction will in general be allowed for our taxable year in which such ordinary income is recognized by the recipient.

 Restricted Stock Units

 No taxable income is recognized upon receipt of restricted stock units. The holder will recognize ordinary income in the year in which the shares subject to the units are issued to the holder. The amount of that income will be equal to the fair market value of the shares on the date of issuance, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder at the time the shares are issued (subject to the limitations described below). The deduction will be allowed for the taxable year in which such ordinary income is recognized.

 Dividend Equivalent Rights

 No taxable income is recognized upon receipt of a dividend equivalent right award. The holder will recognize ordinary income in the year in which a dividend or distribution, whether in cash, securities, or other property, is paid to the holder. The amount of that income will be equal to the fair market value of the cash, securities or other property received, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of the ordinary income recognized by the holder of the dividend equivalent right award at the time the dividend or distribution is paid to such holder (subject to the limitations described below). That deduction will be allowed for the taxable year in which such ordinary income is recognized.

 Other Awards

 In general, no taxable income is recognized upon receipt of other awards. The holder will recognize ordinary income in the year in which the awards are settled, and the participant will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the participant at the time of settlement (subject to the limitations described below). The deduction will be allowed for the taxable year in which such ordinary income is recognized.

 Section 162(m) of the Code

 Subject to certain limitations and terms, Section 162(m) of the Code and its implementing regulations provide that we may not deduct compensation of more than $1,000,000 paid in any year to our CEO and certain other executive officers. While we intend to structure executive compensation to minimize any limitation imposed by Section 162(m) of the Code, we will continue to maintain flexibility and the ability to pay competitive compensation by not requiring all compensation to be deductible to the extent that doing so is consistent with the best interests of our company and stockholders.

 New Plan Benefits under the Plan

 No awards have been made under the Plan based on the increase in the share reserve that is subject to stockholder approval of the amended and restated Plan. Any awards following approval of this proposal to participants shall be at the discretion of the plan administrator Accordingly, the benefits or amounts that may be received by or allocated to each of (i) the officers listed in the Summary Compensation Table, (ii) each of the nominees for election as a director, (iii) all non-employee directors as a group, (iv) all of our present executive officers as a group, and (v) all of our employees, including all other current officers, as a group under the Plan are not determinable at this time.

 Employee Stock Purchase Plan (ESPP)

 In connection with the Business Combination, we adopted the LMF Acquisition Opportunities, Inc. 2022 Employee Stock Purchase Plan (the "ESPP") that became effective upon the Closing. The ESPP is broad-based and allows us to provide an incentive to attract, retain and reward our eligible employees and those of any participating subsidiary companies (whether now existing or subsequently established) with the opportunity to periodically purchase shares of our Common Stock at a discount through their accumulated periodic payroll deductions. The ESPP is intended to qualify as an employee stock purchase plan under Section 423 ("Section

 423") of the Internal Revenue Code of 1986, as amended (the "Code"). Favorable tax treatment is available for United States tax residents participating in a Section 423 plan. The ESPP also authorizes the grant of rights to purchase shares that do not qualify under Section 423 pursuant to rules, procedures or sub-plans adopted by the plan administrator to achieve tax, securities law, or other compliance objectives in particular locations outside of the United States. Up to 380,000 shares of Common Stock will be available for issuance under the ESPP (subject to adjustments).

 Subject to the terms of the ESPP, a committee of two or more Board members appointed by the Board, in its role as plan administrator, has the authority to interpret and construe any provision of the ESPP, establish rules and regulations relating to administering the ESPP, and make all other determinations necessary or advisable for the administration of the ESPP. To the extent applicable law permits, the plan administrator may, to the extent it deems appropriate, delegate, administrative duties.

 Change in Control. In the event of a change in control (as defined in the ESPP), the plan administrator may take such action as deemed appropriate including (i) having the successor entity (or its parent or subsidiary corporation) assume our obligations under the ESPP and the outstanding purchase rights, (ii) accelerating the next purchase date in the then current offering period to a date immediately before the closing date of the change in control, and applying the accumulated payroll deductions to the purchase of shares of our Common Stock at the purchase price in effect for that offering period or (iii) terminating all outstanding purchase rights and refunding all accumulated payroll deductions.

 Health and Welfare Plans

 All of the Company's full-time employees, including its named executive officers, are eligible to participate in its health and welfare plans, including medical, dental, vision, voluntary life insurance, voluntary short-term and long-term disability insurance, and employee assistance program benefits made available to its employees.

 (1) Amounts reflect the director fees earned during fiscal year 2023. As a result of the financial constraints on the Company's cash during 2023, none of the fees were paid during the period covering November 2023 through December (the "Director Fees") 2023. During April of 2024, the Director Fees were paid partly in shares of Common Stock, with the cash portion expected to be paid in the future, as follows:

 (2) Amounts reflect the grant date fair value of restricted stock granted to our non-employee directors calculated in accordance with FASB ASC Topic 718 and accordingly determined on the basis of the closing selling price per share of our common stock on the award date and does not take into account any estimated forfeitures related to service-vesting conditions. For information regarding assumptions underlying the valuation of equity awards, see Notes 2 and 12 to our audited financial statements in the 2023 Annual Report. The restricted stock units granted on April 6, 2023, became fully vested on April 6, 2024, the first anniversary of the date of grant. The non-employee directors held the following restricted stock units on December 31, 2023: Richard Barnett 9,389; Allan Collins, MD 9,389; Andres Lobo 7,978; Ken Van Heel 9,389; Bruce Rodgers 7,978; and Richard Russell 7,978.

 (3) Amounts reflect the grant date fair value of options granted in 2023 calculated in accordance with FASB ASC Topic 718 without taking into account any estimated forfeitures related to service-vesting conditions. SeaStar Medical's named executive officers will only have a benefit to the extent the fair market value of its Common Stock is greater than the exercise price of such stock options. For information regarding assumptions underlying the valuation of equity awards, see Notes 2 and 12 to SeaStar Medical's audited financial statements appearing in the 2023 Annual Report. These options have a one-year vesting period and became fully vested on April 6, 2024. The non-employee director held the following options on December 31, 2023; Richard Barnett 45,838; Allan Collins, MD 44,427; Andres Lobo 19,945; Ken Van Heel 45,838; Bruce Rodgers 19,945; and Richard Russell 19,945.

 Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.

 The following table sets forth information regarding the beneficial ownership of Common Stock on April 16, 2024, by:

 • each person known by the Company to be the beneficial owner of more than 5% of outstanding Common Stock;

 • each of the Company's current named executive officers and directors; and

 • all current executive officers and directors of the Company as a group.

 Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security or the right to acquire such power within 60 days. Except as indicated by the footnotes below, the Company believes, based on the information furnished to it, that the persons and entities named in the table below will have sole voting and investment power with respect to all stock that they beneficially own, subject to applicable community property laws.

 Common stock issuable upon exercise of warrants or options currently exercisable within 60 days are deemed outstanding solely for purposes of calculating the percentage of total voting power of the beneficial owner thereof.

 Subject to the paragraph above, the percentage ownership of Common Stock is based on 75,419,458 shares of Common Stock outstanding as of April 16, 2024.

 Related Person Transaction Policy

 The Company adopted a related person transaction policy that sets forth its procedures for the identification, review, consideration and approval or ratification of related person transactions. For purposes of the Company's policy only, a related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which the Company and any related person are, were or will be participants in which the amount involved exceeds $120,000. Transactions involving compensation for services provided to the Company as an employee or director are not covered by this policy. A related person is any executive officer, director or beneficial owner of more than 5% of any class of the Company's voting securities and any of their respective immediate family members and any entity owned or controlled by such persons.

 Under the policy, if a transaction has been identified as a related person transaction, including any transaction that was not a related person transaction when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, the Company's management must present information regarding the related person transaction to the Company's audit committee, or, if audit committee approval would be inappropriate, to another independent body of the Board, for review, consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests (direct and indirect) of the related persons, the benefits to the Company of the transaction and whether the transaction is on terms that are comparable to the terms available to or from (as the case may be) an unrelated third party or to or from employees generally. Under the policy, the Company will collect information that it deems reasonably necessary from each director, executive officer and, to the extent feasible, significant

 stockholder to enable the Company to identify any existing or potential related person transactions and to effectuate the terms of the policy. In addition, under the Code of Conduct, the Company's employees and directors will have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest. In considering related person transactions, the Company's audit committee, or other independent body of the Board, will take into account the relevant available facts and circumstances including, but not limited to:

 • the risks, costs and benefits to the Company;

 • the impact on a director's independence in the event that the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

 • the availability of other sources for comparable services or products; and

 • the terms available to or from, as the case may be, unrelated third parties or to or from employees generally.

 The policy requires that, in determining whether to approve, ratify or reject a related person transaction, the Company's audit committee, or other independent body of the Board, must consider, in light of known circumstances, whether or not the transaction is consistent with the Company's best interests and those of the Company's stockholders, as the Company's audit committee, or other independent body of the Board, determines in the good faith exercise of its discretion.

 Limitation on Liability and Indemnification of Directors and Officers

 Our Charter limits the liability for directors to the fullest extent permitted under the Delaware General Corporation Law ("DGCL"). The DGCL provides that directors of a corporation will not be personally liable for monetary damages for a breach of their fiduciary duties as directors, except for liability:

 1. for any transaction from which the director derives an improper personal benefit;

 2. for any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

 3. for any unlawful payment of dividends or redemption of shares; or

 4. for any breach of a director's duty of loyalty to the corporation or its stockholders.

 If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the directors will be further eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

 Delaware law and the Bylaws provide that we will, in certain situations, indemnify our directors and officers and may indemnify other employees and agents, to the fullest extent permitted by law. Any indemnified person is also entitled, subject to certain limitations, to advancement, direct payment, or reimbursement of reasonable expenses (including attorneys' fees and disbursements) in advance of the final disposition of the proceeding.

 We maintain a directors' and officers' insurance policy pursuant to which our directors and officers are insured against liability for actions taken in their capacities as directors and officers. We believe these provisions in the Charter and Bylaws are necessary to attract and retain qualified persons as directors and officers.

 Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or control persons, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

 Audit Committee Pre-Approval Policy and Procedures

 The audit committee has policies and procedures that require the pre-approval by the audit committee (or one of its members) of all services performed by the Company's independent registered public accounting firm and related fee arrangements. In the first half of each year, the audit committee approves the proposed services, including the nature, type and scope of services contemplated, and the related fees, to be rendered by these firms during the year. In accordance with this policy, the audit committee or one of its members pre-approved all services to be performed by the Company's independent registered accounting firm.
