Re:          Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to Ocuphire Pharma, Inc., a Delaware corporation (the “Company”), in connection with a Registration Statement on Form S-3 (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission (the “Commission”), for the registration of the Securities (defined below) under the Securities Act of 1933, as amended (the “Securities Act”).

The Registration Statement includes a form of prospectus (the “Prospectus”), which provides that it will be supplemented in the future by one or more supplements to the Prospectus (each, a “Prospectus Supplement”).  The Prospectus, as supplemented by one or more Prospectus Supplements, may cover the offer, issue and sale of (A) (i) shares of common stock, $0.0001 par value per share, of the Company (the “Common Stock”); (ii) one or more series of shares of preferred stock, $0.0001 par value per share, of the Company (the “Preferred Stock”); (iii) warrants to purchase Preferred Stock, Common Stock or Debt Securities (as defined below) (the “Warrants”); and (iv) one or more series of debt securities of the Company (the “Debt Securities”); and (B) the resale of up to 6,987,400 shares (the “Resale Shares”) of Common Stock issuable upon exercise of certain outstanding Series A Warrants and Series B Warrants to purchase shares of Common Stock (the “Series A/Series B Warrants”) currently held by certain selling stockholders.

Any Debt Securities will be issued under one or more indentures in the form to be filed as an exhibit to the Registration Statement (the “Indenture”) relating to the issuance of Debt Securities by the Company.  The Warrants may be issued under one or more warrant agreements (each, a “Warrant Agreement”) between the Company and a third party to be identified therein as warrant agent (each, a “Warrant Agent”).  The Indenture and the Warrant Agreements are herein collectively referred to as the “Agreements.” The shares of Common Stock, shares of Preferred Stock, Debt Securities, Warrants and the Resale Shares are herein collectively referred to as the “Securities.”

In connection with this opinion letter, we have examined and relied upon originals or copies of such records, instruments, certificates, opinions, memoranda and other documents as in our judgment are necessary or appropriate to enable us to render the opinions expressed below.  As to certain factual matters, we have relied upon a certificate of officers of the Company and have not independently sought to verify such matters.  In rendering the opinions in this opinion letter, we have assumed the genuineness and authenticity of all signatures on original documents; the authenticity of all documents submitted to us as originals; the conformity to originals of all documents submitted to us as copies; the accuracy, completeness and authenticity of certificates of public officials; and the due authorization, execution and delivery of all documents where authorization, execution and delivery are prerequisites to the legal effectiveness of such documents.

With respect to our opinions as to the Common Stock to be offered and sold by the Company and the Resale Shares to be offered and sold by the selling stockholders after exercise of the Series A/Series B Warrants, we have assumed that, at the time of issuance and sale, a sufficient number of shares of Common Stock will be authorized and available for issuance and, except for the Resale Shares, that the consideration for the issuance and sale of the Common Stock (or the conversion price for Preferred Stock or Debt Securities convertible into Common Stock or the exercise price for Warrants exercisable for Common Stock) is in an amount that is not less than the par value of the Common Stock.  With respect to our opinion as to the Preferred Stock, we have assumed that, at the time of issuance and sale, a sufficient number of shares of Preferred Stock will be authorized, designated and available for issuance and that the consideration for the issuance and sale of the Preferred Stock (or the conversion price for Debt Securities convertible into Preferred Stock or the exercise price for Warrants exercisable for Preferred Stock) is in an amount that is not less than the par value of the Preferred Stock.  We have also assumed that any Warrants offered under the Registration Statement, and any related Warrant Agreement, will be executed in the forms filed as exhibits to the Registration Statement or any required post-effective amendment thereto or incorporated by reference therein.  We have also assumed that any Debt Securities offered under the Registration Statement will be issued pursuant to the form of Indenture filed as an exhibit to the Registration Statement or any required post-effective amendment thereto or incorporated by reference therein.  We have also assumed that (i) with respect to Securities being issued upon conversion of any convertible Preferred Stock, the applicable convertible Preferred Stock will be duly authorized, validly issued, fully paid and non-assessable; and (ii) with respect to any Securities being issued upon conversion of any convertible Debt Securities or upon exercise of any Warrants, the applicable convertible Debt Securities or Warrants will be valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms.

With your consent, we have also assumed (i) that each of the Agreements, the Debt Securities and the Warrants (collectively, the “Documents”) will be governed by the internal laws of the State of New York, (ii) that each of the Documents has been or will be duly authorized, executed and delivered by the parties thereto, (iii) that each of the Documents constitutes or will constitute legally valid and binding obligations of the parties thereto other than the Company, enforceable against each of them in accordance with their respective terms and (iv) that the status of each of the Documents as legally valid and binding obligations of the parties will not be affected by any (a) breaches of, or defaults under, agreements or instruments, (b) violations of statutes, rules, regulations or court or governmental orders, or (c) failures to obtain required consents, approvals or authorizations from, or to make required registrations, declarations or filings with, governmental authorities.
