Ladies and Gentlemen:

 

We have acted as counsel to Heat Biologics, Inc., a Delaware corporation (the “Company”), in connection with the issuance of (i) 9,200,000 shares (including up to 1,200,000 shares subject to the underwriter’s over-allotment option, which option has been exercised in full by AGP) (the “Shares”) of common stock of the Company, par value $0.0002 per share (the “Common Stock”), (ii) warrants to purchase up to 4,600,000 shares of Common Stock (including up to 600,000 shares subject to the underwriter’s over-allotment option, which option has been exercised in full by AGP) (the “Warrants”), and (iii) the 4,600,000 shares of Common Stock issuable from time to time upon exercise of the Warrants (the “Warrant Shares”). The Shares, the Warrants and the Warrant Shares are included in a Registration Statement on Form S-3 (File No. 333-221201) (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), and declared effective by the Commission on November 13, 2017, a base prospectus, dated November 13, 2017, included in the Registration Statement at the time it originally became effective (the “Base Prospectus”), a preliminary prospectus supplement, dated November 20, 2018, filed with the Commission pursuant to Rule 424(b)(5) under the Securities Act (together with the Base Prospectus, the “Preliminary Prospectus”) and a prospectus supplement, dated November 21, 2018, filed with the Commission pursuant to Rule 424(b)(2) under the Securities Act (together with the Base Prospectus, the “Prospectus”). The Shares, the Warrants and the Warrant Shares are being sold pursuant to an underwriting agreement, dated November 21, 2018, between the Company and A.G.P./Alliance Global Partners, as representative of the several underwriters listed on Schedule 1 thereto (the “Underwriting Agreement”).  The Registration Statement also relates to the common stock purchase rights (the “Rights”) issuable in accordance with the rights agreement, dated as of March 11, 2018, between the Company and Continental Stock Transfer & Trust Company, as Rights Agent (the “Rights Agreement”), which Rights are presently attached to the Common Stock.

 

As counsel to the Company, we have examined the Registration Statement, the Preliminary Prospectus and the Prospectus, and the originals or copies, certified or otherwise identified to our satisfaction, of such other documents, corporate records, certificates of public officials and other instruments as we have deemed necessary for the purposes of rendering this opinion and we are familiar with the proceedings taken and proposed to be taken by the Company in connection with the authorization, issuance and sale of the Shares, the Warrants and the Warrant Shares. In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies.
