Audit Committee Charter

I. Committee Purpose and Responsibilities

The Audit Committee (the “Committee”) of the Board of Directors (the “Board”) of NavSight Holdings, Inc. (the “Company”) is primarily established for the purpose of overseeing the accounting and financial reporting processes of the Company and audits of the financial statements of the Company, and the internal audit function.

The Committee is responsible for assisting the Board’s oversight of (1) the quality and integrity of the Company’s financial statements and related disclosure, (2) the Company’s compliance with legal and regulatory requirements, (3) the independent auditor’s qualifications and independence, and (4) the performance of the Company’s internal audit function, including with respect to audits of the Company’s information technology environment, and the independent auditor.

II. Committee Membership

Subject to the applicable phase-in periods permitted by the rules of the New York Stock Exchange (“NYSE”), the Committee shall consist of three or more members of the Board, each of whom the Board has determined has no material relationship with the Company and each of whom shall meet all applicable independence, financial literacy and other requirements of the NYSE and Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). At least one member shall be an “audit committee financial expert” as defined by the applicable rules of the Securities and Exchange Commission (the “SEC”). The members of the Committee shall be appointed by and shall serve at the pleasure of the Board for such term or terms as the Board may determine.

No member of the Committee may serve on the audit committee of more than three public companies, including the Company, unless the Board has determined that such simultaneous service would not impair the ability of such member to effectively serve on the Committee.

III. Authority and Duties

The following list of duties is not exhaustive, and the Committee may, in addition, perform such other functions as may be necessary or appropriate for the performance of its oversight function.

Independent Auditor’s Qualifications and Independence

The Committee shall be solely responsible for the appointment, retention, compensation and oversight of the work of the independent auditor employed by the Company (including resolution of disagreements between management and the independent auditor regarding financial reporting) for the purpose of preparing or issuing an audit report or permitted related audit, review or attest services. The independent auditor shall report directly to the Committee.

The Committee shall have the sole authority to preapprove any audit and non-audit services to be provided by the independent auditor, and to adopt policies and procedures in connection therewith. The Committee shall review with the lead audit partner whether any of the audit team members receive any discretionary compensation from the audit firm with respect to non-audit services performed by the independent auditor.

The Committee shall obtain and review, annually or more frequently as the Committee considers appropriate, a report by the independent auditor describing: the independent auditor’s internal quality-control procedures; any material issues raised by the most recent internal quality-control review, or peer review, of the independent auditor, or by any inquiry, review or investigation by governmental, professional or other regulatory authorities, within the preceding five years, respecting independent audits carried out by the independent auditor, and any steps taken to address any such issues; and (to assess the independent auditor’s independence) all relationships between the independent auditor and the Company. The Committee shall, in addition to assuring the regular rotation of the lead (or coordinating) audit partner and the audit partner responsible for reviewing the audit, consider whether there should be regular rotation of the audit firm in the interest of assuring continuing independence of an independent auditor, and report its conclusions to the Board.

The Committee shall review the experience, qualifications and performance of the senior members of the independent auditor team.

The Committee shall preapprove the hiring of any employee or former employee of the independent auditor who was a member of the Company’s audit team during the preceding three fiscal years.

In addition, the Committee shall review with the independent auditor any audit problems or difficulties and management’s response, and any significant disagreements with management.

IV. Clarification of Audit Committee’s Role

The Committee’s responsibility is one of oversight. It is the responsibility of the Company’s management to prepare consolidated financial statements in accordance with applicable law and regulations and of the Company’s independent auditor to audit those financial statements. It is not the responsibility of the Committee to duplicate the activities of management or the independent auditor or to provide expert or special assurance as to, or otherwise certify, the Company’s financial statements or internal control over financial reporting, the independent auditor’s work or compliance of the financial statements with GAAP. The Committee fulfills its oversight role on the basis of the information it receives from management and the independent auditor. Therefore, in carrying out its oversight responsibilities, each member of the Committee shall be entitled to rely, to the fullest extent permitted by law, on the integrity of those persons and organizations within and outside the Company from whom he or she receives information, and the accuracy of the financial and other information provided to the Committee by such persons or organizations.

V. Committee Structure and Operations

The Board shall designate one member of the Committee as its chairperson. The Committee shall meet at least four times per year at a time and place determined by the Committee chairperson, with further meetings to occur, or actions to be taken by unanimous written consent, when deemed necessary or desirable by the Committee or its chairperson. Members of the Committee may participate in a meeting of the Committee by means of conference call or similar communications equipment by means of which all persons participating in the meeting can hear each other.

The Committee shall meet separately, periodically, with management, the internal auditors and the independent auditor. The Committee shall report regularly to the entire Board on Committee findings and recommendations and any other matters the Committee deems appropriate or the Board requests, and maintain minutes or other records of Committee meetings and activities.

VI. Delegation to Subcommittee

The Committee may, in its discretion, delegate all or a portion of its duties and responsibilities to a subcommittee of the Committee.

VII. Performance Evaluation

The Committee shall conduct an annual performance evaluation of the Committee, which evaluation shall compare the performance of the Committee with the requirements of this charter. The performance evaluation by the Committee shall be conducted in such manner as the Committee deems appropriate. The Committee shall also review its charter annually and approve any improvements necessary or desirable to the Committee.

VIII. Resources and Authority

In discharging its oversight role, the Committee shall have full access to all Company books, records, facilities and personnel of the Company. The Committee may retain counsel, auditors or other advisors, in its sole discretion and agree to such fees and other retention terms with any provider of services to the Committee as the Committee may deem necessary. The Company shall provide appropriate funding, as determined by the Committee, for payment of the independent auditor, any independent counsel or other advisors retained by the Committee, and any ordinary administrative expenses of the Committee.
