Re: Registration Statement on Form S-4

Ladies and Gentlemen:

We have acted as special counsel to Apex Technology Acquisition Corporation, a Delaware corporation (the “Company”), in connection with the proposed issuance of up to 162,308,880 shares of common stock, par value $0.0001 per share (the “Shares”), to be issued in connection with the merger contemplated by that certain Business Combination Agreement and Plan of Reorganization, dated as of November 23, 2020, as amended on December 30, 2020, March 8, 2021 and May 18, 2021 (the “Business Combination Agreement”), by and among the Company, Athena Technology Merger Sub, Inc., a Delaware corporation, Athena Technology Merger Sub 2, LLC, a Delaware limited liability company, and AvePoint, Inc., a Delaware Corporation (“AvePoint”). The Shares are included in a registration statement on Form S–4 under the Securities Act of 1933, as amended (the “Act”), initially filed with the Securities and Exchange Commission (the “Commission”) on February 4, 2021 (Registration No. 333–252712) (as amended, the “Registration Statement”). This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or the related proxy statement/prospectus, other than as expressly stated herein with respect to the issue of the Shares.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company and others as to factual matters without having independently verified such factual matters. We are opining herein as to the General Corporation Law of the State of Delaware (the “DGCL”), and we express no opinion with respect to any other laws.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof, when the Shares have been duly registered on the books of the transfer agent and registrar therefor in the name or on behalf of the applicable AvePoint stockholders and have been issued by the Company against payment therefor (not less than par value) in the circumstances

contemplated by the Registration Statement and the Business Combination Agreement, the issue and sale of the Shares will have been duly authorized by all necessary corporate action of the Company, and the Shares will be validly issued, fully paid and nonassessable.

This opinion is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act. We consent to your filing this opinion as an exhibit to the Registration Statement and to the reference to our firm in the proxy statement/prospectus included in the Registration Statement under the heading “Legal Matters.” In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.

Very truly yours,
