Ladies and Gentlemen:

We have acted as legal counsel to Spring Bank Pharmaceuticals, Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a Prospectus Supplement, dated August 9, 2018 (the “Prospectus Supplement”), to a Registration Statement (File No. 333-218399) on Form S-3 (the “Registration Statement”), filed by the Company with the Commission under the Securities Act of 1933, as amended (the “Securities Act”).  The Prospectus Supplement relates to the sale of an aggregate of 3,450,000 shares (the “Shares”) of the Company’s common stock, $0.0001 par value per share (the “Common Stock”), including 450,000 shares subject to the underwriters’ option to purchase additional shares, to Jefferies LLC and Piper Jaffray & Co., as representatives of the underwriters (the “Underwriters”), pursuant to an Underwriting Agreement dated August 8, 2018 between the Company and the Underwriters (the “Underwriting Agreement”).  The Underwriting Agreement will be filed as an exhibit to a Current Report on Form 8-K and incorporated by reference into the Registration Statement.  This opinion is being rendered in connection with the filing of the Prospectus Supplement with the Commission.  All capitalized terms used herein and not otherwise defined shall have the respective meanings given to them in the Registration Statement.

In connection with this opinion, we have examined the Company’s Restated Certificate of Incorporation and Amended and Restated Bylaws, each as currently in effect, the Registration Statement and the exhibits thereto, the Prospectus Supplement and the Underwriting Agreement and such other records of the corporate proceedings of the Company and certificates of the Company’s officers as we have deemed relevant.

In our examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies and the authenticity of the originals of such copies.

Our opinion is limited to the General Corporation Law of the State of Delaware and we express no opinion with respect to the laws of any other jurisdiction.  No opinion is expressed herein with respect to the qualification of the Shares under the securities or blue sky laws of any state or any foreign jurisdiction.
