Exhibit 99.3

LIFESCI ACQUISITION III CORP.

COMPENSATION COMMITTEE CHARTER

OF THE BOARD OF DIRECTORS

Purpose of the Committee

The purposes of the Compensation Committee (the “Committee”) of the Board of Directors (the “Board”) of LifeSci Acquisition III Corp. (the “Company”) shall be to oversee the Company’s compensation and employee benefit plans and practices, including its executive, director and other incentive and equity-based compensation plans and to review and prepare any disclosures required to be made by the Company in its periodic filings with the Securities and Exchange Commission (“SEC”) pursuant to the rules and regulations of the SEC.

This Charter is intended as a tool within which the Board, assisted by its committees, directs the affairs of the Company. While it should be interpreted in the context of all applicable laws, regulations and listing requirements, as well as in the context of the Company’s charter and bylaws (“Governing Documents”), it is not intended to establish by its own force any legally binding obligations.

Composition of the Committee

The members of the Committee shall be appointed by the Board on the recommendation of the Nominating and Corporate Governance Committee. The Board may designate one member of the Committee as its Chairperson and in the absence of any such designation by the Board, the Committee shall designate by majority vote of the full Committee one member of the Committee as its Chairperson. Vacancies on the Committee shall be filled by majority vote of the Board at the next meeting of the Board following the occurrence of the vacancy or by written consent of the Board. No member of the Committee shall be removed except by majority vote of the Board. The Board may remove any member from the Committee at any time with or without cause.

The Committee shall be comprised of directors, each of whom meets the independence requirements established by the Board and applicable laws, regulations and listing requirements of the Nasdaq Stock Market, except that the Committee may have as one of its members a “non-independent director” under exceptional and limited circumstances pursuant to the exemption under Rule 5605(d)(2)(B) of the Nasdaq Stock Market. At least two of the Committee members shall be “non-employee directors” as defined by Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The members of the Committee and the chairperson shall be selected not less frequently than annually by the Board and serve at the pleasure of the Board. A Committee member (including the chairperson) may be removed at any time, with or without cause, by the Board. Each member shall also be free of any relationship that, in the judgment of the Board, would interfere with the exercise of his or her independent judgment.

Meetings and Procedures of the Committee

The Committee may fix its own rules of procedure, which shall be consistent with the Governing Documents. The Committee shall meet at least annually, or more frequently as circumstances require. The Chairperson of the Committee or a majority of the members of the Committee may also call a special meeting of the Committee. A majority of the members of the Committee present in person or by means of a conference telephone or other communications equipment by means of which all persons participating in the meeting can hear each other shall constitute a quorum. Any action required or permitted to be taken at any meeting of the Committee may be taken without a meeting, if all members of the Committee consent thereto in writing, and the writing or writings are filled with the minutes of proceedings of the Committee.

The Committee may request that any directors, officers or employees of the Company, or other persons whose advice and counsel are sought by the Committee, attend any meeting of the Committee to provide such pertinent information as the Committee requests. The Company’s Chief Executive Officer (“CEO”) shall not attend the portion of any meeting where the CEO’s performance or compensation are discussed.

The Compensation Committee shall report to the Board on Committee findings, recommendations and other matters the Committee deems appropriate or the Board requests. The Committee shall keep written minutes of its meetings, which minutes shall be maintained with the books and records of the Company.

Delegation of Authority

The Committee may form subcommittees for any purpose that the Committee deems appropriate and may delegate to such subcommittees such power and authority as the Committee deems appropriate; provided, however, that the Committee shall not delegate to a subcommittee any power or authority required by any law, regulation or listing standard to be exercised by the Committee as a whole.

The Committee may also delegate to one or more executive officers of the Company the authority to make grants of equity-based compensation to eligible individuals who are not executive officers. Any executive officer to whom the Committee grants such authority shall regularly report to the Committee grants so made and the Committee may revoke any delegation of authority at any time.

Committee Responsibilities

The primary responsibilities of the Committee shall be to:

• Ensure that the Company’s executive compensation programs are designed to enable it to recruit, retain and motivate a large group of talented and diverse executives.

• Ensure that the Company’s executive compensation programs are appropriately competitive, support organization objectives and stockholder interests, and ensure executive compensation is adequately designed to align the interests of executive officers with the long-term performance of the Company.

• Oversee all employee benefit plans and programs of the Company, its subsidiaries and divisions, including the authority to adopt, amend and terminate such plans and programs (unless approval by the Board or stockholders is required by law).

• Review and approve annual corporate goals and objectives relevant to the CEO’s compensation; evaluate the CEO’s performance in light of those goals and objectives; and recommend for approval by the independent members of the Board, the CEO’s compensation level based on this evaluation.

• The Committee shall produce the annual Compensation Committee Report for inclusion in the Company’s proxy statement in compliance with the rules and regulations promulgated by the SEC.

• Annually assess and report to the Board on the performance and effectiveness of the Committee.

Investigations and Studies; Outside Advisers

The Committee may conduct or authorize investigations into or studies of matters within the Committee’s scope of responsibilities, and may retain, at the Company’s expense, such independent legal counsel or other consultants or advisers as it deems necessary and appropriate, including compensation consultants to advise the Committee with respect to amounts or forms of executive or director compensation, and may rely on the integrity and advice of any such counsel or other advisers. It is the Committee’s intention that any compensation consultant engaged to advise the Committee with respect to executive and director compensation will not engage in work for the Company that is unrelated to executive and director compensation advisory services without prior approval of the Committee Chairperson.

The Committee shall be directly responsible for the appointment, compensation and oversight of the work of any such compensation consultant, legal counsel and other adviser retained by the Committee. The Company shall provide for appropriate funding, as determined by the compensation committee, for payment of reasonable compensation to a compensation consultant, legal counsel or any other adviser retained by the compensation committee. The Committee shall have sole authority to approve related fees and retention terms.

The Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Committee, other than in-house legal counsel, only after taking into consideration all factors relevant to the adviser’s independence from management, including those specified in the Nasdaq listing rules and the following factors:

• the provision of other services to the Company by the person that employs the compensation consultant, legal counsel or other adviser;

• the amount of fees received from the Company by the person that employs the compensation consultant, legal counsel or other adviser, as a percentage of the total revenue of the person that employs the compensation consultant, legal counsel or other adviser;

• the policies and procedures of the person that employs the compensation consultant, legal counsel or other adviser that are designed to prevent conflicts of interest;

• any business or personal relationship of the compensation consultant, legal counsel or other adviser with a member of the Committee;

• any stock of the Company owned by the compensation consultant, legal counsel or other adviser; and

• any business or personal relationship of the compensation consultant, legal counsel, other adviser or the person employing the adviser with a member of senior management.

Notwithstanding the foregoing, the Committee is not required to conduct an independence assessment for a compensation adviser that acts in a role limited to the following activities for which no disclosure is required under Item 407(e)(3)(iii) of Regulation S-K promulgated by the SEC: (a) consulting on any broad-based plan that does not discriminate in scope, terms, or operation, in favor of Executive Officers or directors of the Company, and that is available generally to all salaried employees; and/or (b) providing information that either is not customized for the Company or that is customized based on parameters that are not developed by the adviser, and about which the adviser does not provide advice.
