We have acted as legal counsel to Intensity Therapeutics, Inc., a Delaware corporation (the “Company”), in connection with the filing by the Company of a Registration Statement on Form S-3 (as amended, the “Registration Statement”) with the Securities and Exchange Commission (the “Commission”) relating to the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the offering from time to time by the selling stockholders, as described in the Registration Statement, of up to 394,500 shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), composed of (i) 273,000 shares issuable upon the exercise of warrants issued by the Company as compensation for consulting services, (ii) 42,500 shares issuable upon the exercise of warrants issued by the Company as an incentive for holders to participate in the Company’s Series A preferred financing, (iii) 49,000 shares issuable upon the exercise of warrants issued by the Company as compensation for placement agents, and (iv) 30,000 shares issuable upon the exercise of warrants issued by the Company to purchasers in a convertible note financing (collectively, the “Warrants”).

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

No opinion is expressed herein with respect to the qualification of the Conversion Shares and Warrant Shares under the securities or blue sky laws of any state or any foreign jurisdiction.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that the Warrant Shares, when delivered and paid for in accordance with the terms of the Warrants, will be validly issued, fully paid and non-assessable.
