Re: Registration Statement on Form S-8: 377,535 shares of common stock, par value $0.0001 per share

Ladies and Gentlemen:

We have acted as special counsel to 五星体育直播, a Delaware corporation (the 聯Company聰), in connection with the registration by the Company of 377,535 shares of common stock of the Company, par value $0.0001 per share (the 聯Shares聰), issuable under the 五星体育直播 John Nicols Stock Option Grant Notice and Stock Option Agreement (the 聯Inducement Grant聰). The Shares are included in a registration statement on Form S-8 under the Securities Act of 1933, as amended (the 聯Securities Act聰), filed with the Securities and Exchange Commission (the 聯Commission聰) on May 11, 2018 (the 聯Registration Statement聰). This opinion is being furnished in connection with the requirements of Item听601(b)(5) of Regulation S-K under the Securities Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or the prospectus forming a part thereof, other than as expressly stated herein with respect to the issuance 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 聯DGCL聰), 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 shall have been duly registered on the books of the transfer agent and registrar therefor in the name or on behalf of the purchaser, and have been issued by the Company against payment therefor (not less than par value) in the circumstances contemplated by and pursuant to the Inducement Grant, the issuance 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 non-assessable. In rendering the foregoing opinion, we have assumed that the Company will comply with all applicable notice requirements regarding uncertificated shares provided in the DGCL.

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 Securities Act. We consent to your filing this opinion as an exhibit to the Registration Statement. In giving such

consent, we do not thereby admit that we are in the category of persons whose consent is required under Section听7 of the Securities Act or the rules and regulations of the Commission thereunder.

Very truly yours,
/s/ Latham听& Watkins LLP
