(SEC Registration Statement on Form S-1, File Number 333-264518).

I. PURPOSE

The Board of Directors (the "Board") of Lumos Analytics Inc., a Delaware corporation (the "Company"), hereby establishes the Audit Committee of the Board (the "Committee") to assist the Board in fulfilling its corporate governance and oversight responsibilities. The Committee is established by and among the members of the Board and shall operate in accordance with the provisions of this Charter.

The primary purpose of the Committee is to assist the Board in its oversight of:

(a) the integrity of the Company's financial statements and financial reporting process;

(b) the Company's compliance with legal and regulatory requirements applicable to its financial reporting and disclosure obligations;

(c) the qualifications, independence, and performance of the Company's independent registered public accounting firm (the "independent auditor");

(d) the performance of the Company's internal audit function, once established; and

(e) the Company's systems of internal controls over financial reporting and the effectiveness of the Company's disclosure controls and procedures.

In discharging its oversight role, the Committee shall endeavor to maintain free and open communication among the independent auditor, the Company's management, the internal audit function (when established), and the Board. The Committee shall encourage and facilitate the continuous improvement of, and foster adherence to, the Company's accounting policies, procedures, and practices at all levels.

The Committee shall operate in a manner designed to comply with the requirements of Nasdaq Listing Rule 5605(c) and Rule 10A-3 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as well as all other applicable laws, rules, and regulations governing the responsibilities and authority of audit committees of publicly listed companies.

While the Committee has the responsibilities and powers set forth in this Charter, the Committee's role is one of oversight. The members of the Committee are not full-time employees of the Company and may or may not be accountants or auditors by profession, and, in any event, do not serve in such capacity. Consequently, it is not the duty or responsibility of the Committee to conduct "field work" or other types of auditing or accounting reviews or procedures, and each member of the Committee shall be entitled to rely on (i) the integrity of those persons and organizations within and outside the Company from which it receives information and (ii) the accuracy of the financial and other information provided to the Committee by such persons or organizations absent actual knowledge to the contrary (which shall be promptly reported to the Board).

II. COMPOSITION

A. Number of Members

The Committee shall consist of no fewer than three (3) members of the Board, each of whom shall satisfy the independence and other qualification requirements set forth in this Section II. The Board shall determine the exact number of Committee members from time to time.

Upon the effectiveness of the Company's Registration Statement on Form S-1 (SEC File Number 333-264518) and the closing of the Company's initial public offering, the initial members of the Committee shall be:

1. Samuel Adebayo (Chair)

2. Diane Ochoa

3. Catherine Mercer

B. Independence Requirements

Each member of the Committee must satisfy all applicable independence requirements, including, without limitation, the following:

(i) Each member must be "independent" as defined in Nasdaq Listing Rule 5605(a)(2), as determined by the Board in its business judgment, and must satisfy the additional independence requirements for audit committee members set forth in Nasdaq Listing Rule 5605(c)(2)(A).

(ii) Each member must satisfy the independence requirements of Rule 10A-3(b)(1) promulgated under the Exchange Act, including the requirement that, in order to be considered independent for purposes of serving on the Committee, a member may not accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the Company or any subsidiary thereof, other than in his or her capacity as a member of the Board or any committee of the Board. For the avoidance of doubt, compensatory fees do not include the receipt of fixed amounts of compensation under a retirement plan (including deferred compensation) for prior service with the Company, provided that such compensation is not contingent in any way on continued service.

(iii) No member of the Committee may be an "affiliated person" of the Company or any subsidiary thereof, as that term is defined in Rule 10A-3 under the Exchange Act, other than in his or her capacity as a member of the Board or any committee of the Board.

In light of the Company's dual-class capital structure, in which shares of Class B Common Stock held by the Company's co-founders, Priya Subramanian (Chief Executive Officer and Chair of the Board) and Marcus Henley (Chief Technology Officer), carry ten (10) votes per share, the Board shall take particular care in evaluating the independence of each Committee member. Specifically, each member of the Committee must be independent of both the Company's management and the holders of Class B Common Stock, and no member shall have any material relationship with Priya Subramanian, Marcus Henley, or any entity controlled by either of them that would interfere with the exercise of the member's independent judgment in carrying out the responsibilities of a Committee member.

If any member of the Committee ceases to be independent for any reason, such member shall promptly notify the Board, and the Board shall take appropriate action to replace such member in accordance with the requirements of this Charter and applicable law.

C. Financial Literacy and Audit Committee Financial Expert

Each member of the Committee must be able to read and understand fundamental financial statements, including a company's balance sheet, income statement, and cash flow statement, at the time of his or her appointment to the Committee, in accordance with Nasdaq Listing Rule 5605(c)(2)(A). The Board shall assess and make a determination regarding the financial literacy of each Committee member at the time of his or her appointment and annually thereafter.

At least one member of the Committee must qualify as an "audit committee financial expert" as that term is defined in Item 407(d)(5) of Regulation S-K promulgated under the Securities Act of 1933, as amended (the "Securities Act"), and the Exchange Act. A person shall be deemed to have the attributes of an audit committee financial expert if such person has the following attributes:

(a) an understanding of generally accepted accounting principles ("GAAP") and financial statements;

(b) the ability to assess the general application of such principles in connection with the accounting for estimates, accruals, and reserves;

(c) experience preparing, auditing, analyzing, or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Company's financial statements, or experience actively supervising one or more persons engaged in such activities;

(d) an understanding of internal controls over financial reporting; and

(e) an understanding of audit committee functions.

The Board has determined that Samuel Adebayo qualifies as an audit committee financial expert based on his extensive experience as the former Chief Financial Officer of Verdant Software Corp., a publicly listed enterprise software company, where he served from 2014 through 2020 and was responsible for all aspects of financial reporting, internal controls, and audit oversight. The designation of Mr. Adebayo as the Committee's audit committee financial expert shall be disclosed in the Company's Registration Statement on Form S-1 (SEC File Number 333-264518) and in subsequent annual proxy statements filed with the Securities and Exchange Commission (the "SEC"), in accordance with the requirements of Item 407(d)(5) of Regulation S-K.

The designation of a member as an audit committee financial expert shall not impose upon such person any duties, obligations, or liabilities that are greater than the duties, obligations, and liabilities imposed on such person as a member of the Committee and the Board in the absence of such designation, and shall not affect the duties, obligations, or liabilities of any other member of the Committee or the Board.

D. Appointment and Removal

Members of the Committee shall be appointed by the Board, upon the recommendation of the Nominating and Corporate Governance Committee of the Board (currently chaired by Diane Ochoa), and shall serve at the pleasure of the Board. Each member of the Committee shall serve until his or her successor is duly appointed by the Board, or until his or her earlier resignation, removal, or death.

The Board may remove any member of the Committee at any time, with or without cause, by a resolution adopted by a majority of the Board. Any vacancy on the Committee, whether arising from death, resignation, removal, increase in the number of members, or otherwise, shall be filled by the Board upon the recommendation of the Nominating and Corporate Governance Committee, subject to the independence and qualification requirements set forth in this Section II.

E. Chair. The Board shall designate one member of the Committee to serve as the Chair of the Committee. The initial Chair of the Committee shall be Samuel Adebayo. If the Chair is not present at any meeting of the Committee, the members of the Committee present at such meeting shall select one of their number to act as chair of such meeting.

The Chair shall be responsible for:

(i) presiding at all meetings of the Committee;

(ii) setting the agenda for each meeting of the Committee, in consultation with management, the internal audit function (when established), and the independent auditor;

(iii) ensuring that the Committee fulfills its responsibilities under this Charter;

(iv) reporting regularly to the full Board regarding the activities, findings, and recommendations of the Committee; and

(v) performing such other duties as may be assigned by the Board or the Committee from time to time.

III. MEETINGS

A. Frequency. The Committee shall meet at least four (4) times per fiscal year, and more frequently as circumstances require, as determined by the Chair in consultation with the other members of the Committee. The Committee's meeting schedule shall, to the extent practicable, be coordinated with the Company's quarterly financial reporting cycle so as to permit timely review of the Company's quarterly and annual financial statements and related disclosures.

In addition to its regularly scheduled meetings, the Committee shall meet separately and periodically with each of the following:

(i) Management — to discuss the Company's financial reporting processes, internal controls, and any other matters that the Committee or management deems appropriate;

(ii) Internal audit personnel — once such function has been established, to discuss the scope and results of internal audit activities, the adequacy of the Company's internal controls, and any other matters that the Committee or internal audit personnel deem appropriate; and

(iii) The independent auditor — currently Meridian & Howe LLP (audit engagement partner: Gregory Simmons) — to discuss the scope of the annual audit, the results of the audit examination, any difficulties or disagreements with management encountered during the course of the audit, and any other matters that the Committee or the independent auditor deems appropriate, including those matters required to be discussed by applicable auditing standards.

The Committee may request that any such meetings be held outside the presence of other parties, including members of management, when the Committee deems it necessary or advisable.

B. Quorum and Voting

A majority of the members of the Committee then in office shall constitute a quorum for the transaction of business. Any action of the Committee shall require the affirmative vote of a majority of the members present at a meeting at which a quorum is present. No member of the Committee shall vote by proxy.

The Committee may act by unanimous written consent of all members of the Committee in lieu of a meeting, to the extent permitted by applicable law and the Company's Amended and Restated Bylaws. Any such written consent shall be filed with the minutes of proceedings of the Committee and shall have the same force and effect as a vote taken at a duly called meeting at which a quorum was present.

C. Attendance and Participation

The Committee may invite any director, officer, or employee of the Company, or any representative of the Company's advisors, to attend meetings of the Committee and to provide pertinent information as requested by the Committee. Without limiting the generality of the foregoing, the Committee anticipates that the following individuals will be regular attendees at Committee meetings:

(i) Naomi Feinberg, General Counsel of the Company;

(ii) David Lau, Chief Financial Officer of the Company; and

(iii) Gregory Simmons, audit engagement partner, Meridian & Howe LLP.

Notwithstanding the foregoing, the Committee shall have the authority to exclude any person from all or any portion of any Committee meeting when the Committee determines that such exclusion is necessary or advisable to protect the integrity of the Committee's deliberations, including, without limitation, executive sessions of the Committee without management present.

The independent auditor, currently Meridian & Howe LLP, shall have direct and unrestricted access to the Committee at all times and may communicate directly with the Committee, the Chair, or any individual member at any time, without the need for management approval or involvement.

D. Minutes. The Committee shall maintain written minutes or other records of its meetings, which shall be filed with the minutes of the meetings of the Board. The Chair, or such other person as the Committee may designate, shall be responsible for the preparation and distribution of minutes of each meeting to the members of the Committee and to the Corporate Secretary of the Company. The Committee shall report regularly to the Board on its activities, findings, and recommendations, and shall provide such additional reports to the Board as the Board may request from time to time.

The Committee shall discuss with management and the independent auditor any significant deficiency or material weakness identified by either management or the independent auditor, and shall review management's plans for remediation of any such deficiency or weakness.

2. Disclosure Controls and Procedures. The Committee shall review the Company's disclosure controls and procedures, including the certifications made by the Chief Executive Officer and the Chief Financial Officer pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, as amended, and the rules and regulations promulgated thereunder.

(a) Customer Concentration Risk. As of the date of this Charter, the Company's ten (10) largest customers represent approximately 34% of annual recurring revenue ("ARR"). The Committee shall monitor the concentration of the Company's revenue base and the risks associated with the potential loss of one or more significant customers.

The Company maintains a revolving credit facility with Ashford National Bank, with a total commitment amount of $50,000,000, bearing interest at a rate equal to the Secured Overnight Financing Rate ("SOFR") plus 275 basis points. As of March 31, 2022, approximately $15,000,000 was drawn under this facility.

4. Establishment of Internal Audit Function. As of the date of preparation of this Charter, the Company does not have a dedicated internal audit function. The Committee acknowledges that the establishment of an internal audit function is an important component of the Company's overall internal control framework. Following the closing of the Company's initial public offering, the Committee shall oversee the establishment of an internal audit function as appropriate for the Company's size, complexity, and risk profile, and shall work with management to develop a timeline and plan for the implementation of such function. Until such time as the internal audit function is established, the Committee shall take appropriate steps to satisfy itself regarding the adequacy of the Company's internal controls through other means, including enhanced oversight of management's assessment of internal controls and coordination with the independent auditor.

E. Compliance and Legal Matters

1. Whistleblower Procedures. The Committee shall establish and oversee procedures for:

(a) the receipt, retention, and treatment of complaints received by the Company regarding accounting, internal accounting controls, or auditing matters; and

(b) the confidential, anonymous submission by employees of the Company of concerns regarding questionable accounting or auditing matters,

in each case as required by Rule 10A-3(b)(3) under the Exchange Act. The Committee shall review the procedures on a periodic basis to ensure their continued effectiveness and shall review any significant complaints received through such procedures.

2. Legal Matters. The Committee shall review with the Company's General Counsel, Naomi Feinberg, any legal matters (including pending or threatened litigation, regulatory investigations, or compliance matters) that could have a significant impact on the Company's financial statements or financial condition. The Committee shall also review with the General Counsel any material reports or inquiries received from regulators or governmental agencies that relate to the Company's financial reporting, accounting policies, or internal controls.

The Committee shall prepare the Audit Committee report required by SEC rules (Item 407(d)(3) of Regulation S-K and Schedule 14A) to be included in the Company's annual proxy statement. Such report shall state, among other things, whether the Committee has (a) reviewed and discussed the audited financial statements with management, (b) discussed with the independent auditor the matters required to be discussed by applicable PCAOB auditing standards, and (c) received the written disclosures and letter from the independent auditor regarding independence required by applicable PCAOB rules, and whether, based on such review and discussions, the Committee has recommended to the Board that the audited financial statements be included in the Company's annual report on Form 10-K.

2. Regular Reporting to the Board. The Committee shall report regularly to the Board regarding the Committee's activities, findings, issues, and recommendations, including a summary of any significant matters discussed at each Committee meeting and any actions taken by the Committee between meetings. Such reports shall be provided at the next regularly scheduled meeting of the Board following each Committee meeting, or more frequently as circumstances require.

3. Issues Regarding Financial Integrity, Compliance, and Auditor Performance. The Committee shall review with the full Board any issues that arise with respect to:

(a) the quality or integrity of the Company's financial statements;

(b) the Company's compliance with legal or regulatory requirements;

(c) the performance and independence of the independent auditor; or

(d) the performance of the internal audit function (once established).

The Committee shall make recommendations to the Board with respect to the resolution of any such issues.

VI. ANNUAL PERFORMANCE EVALUATION

The Committee shall conduct an annual self-evaluation of its own performance and the adequacy of this Charter, including a review of whether the Committee has fulfilled its responsibilities as set forth herein. The annual performance evaluation may take such form as the Committee deems appropriate, including a written questionnaire, a discussion among Committee members, or interviews with individual members, and may be conducted by the Committee itself or by an independent third party retained by the Committee.

The Committee shall review and reassess the adequacy of this Charter at least annually and shall recommend any proposed changes to the Board for approval. In connection with such review, the Committee shall consider whether any changes to the Charter are warranted in light of changes in applicable law, regulations, or listing standards, as well as changes in the Company's business, operations, or organizational structure.

The results of the annual self-evaluation shall be reported to the Board, along with any recommendations for improvements in the Committee's processes, procedures, or composition.

VII. LIMITATIONS OF THE COMMITTEE'S ROLE

While the Committee has the responsibilities and powers set forth in this Charter, the Committee's role is fundamentally one of oversight. The Committee recognizes that the Company's management is responsible for the preparation, presentation, and integrity of the Company's financial statements, and for maintaining appropriate accounting and financial reporting principles and policies and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations.

The independent auditor is responsible for planning and carrying out a proper audit of the Company's annual financial statements in accordance with the standards of the Public Company Accounting Oversight Board ("PCAOB"), and for performing timely reviews of the Company's quarterly financial statements prior to the filing of each quarterly report on Form 10-Q.

Nothing in this Charter shall be construed to reduce the responsibilities or liabilities of the Company's management or the independent auditor. In particular, nothing in this Charter shall be construed as implying that the Committee has assumed, or has the authority to assume, management's responsibilities for the preparation of the Company's financial statements or the independent auditor's responsibilities for the audit thereof.

The members of the Committee are not employees of the Company and are not, and do not represent themselves to be, accountants or auditors by profession or experts in the fields of accounting or auditing. It is not the duty or responsibility of the Committee to plan or conduct audits or to determine that the Company's financial statements and disclosures are complete and accurate and are in accordance with GAAP and applicable rules and regulations. Each member of the Committee shall be entitled to rely on the integrity of those persons within the Company and of the professionals and experts (including the Company's independent auditor and internal auditors) from which the Committee receives information, and the accuracy and completeness of the financial and other information provided to the Committee by such persons, professionals, and experts, absent actual knowledge to the contrary (which shall be promptly reported to the Board).

Nothing in this Charter is intended to, or shall be deemed to, expand applicable standards of liability under federal or state law for directors of the Company, including the members of the Committee.

VIII. EFFECTIVE DATE AND AMENDMENT

This Charter shall become effective upon its adoption by the Board of Directors, which is expected to occur in connection with and contingent upon the closing of the Company's initial public offering of Class A Common Stock on the Nasdaq Global Select Market under the proposed ticker symbol "LMSA."

This Charter may be amended by the Board of Directors at any time, upon recommendation of the Committee. Any amendment to this Charter shall be disclosed as required by applicable law, SEC rules, and Nasdaq listing standards.

A copy of this Charter, as then in effect, shall be posted on the Company's website following the closing of the initial public offering, and shall be made available in print to any stockholder who requests it, in each case in accordance with applicable SEC rules.
