Ladies & Gentlemen:

We have acted as special New York counsel to Uranium Energy Corp., a Nevada corporation (the "Company"), in connection with the filing by the Company of a Registration Statement on Form S-3 (the  "Registration Statement") with the Securities and Exchange Commission (the "Commission") pursuant to the Securities Act of 1933, as amended (the "Act"), for the registration of the offer and sale by the Company from time to time of up to $100,000,000 aggregate initial offering price of (i) the Company's common shares, par value $0.001("Common Shares"), (ii) debt securities ("Debt Securities") which may be issued under one or more indentures, as may be supplemented from time to time (each an "Indenture") between the Company and a trustee for the holders of the Debt Securities, or without any indenture, (iii) warrants to purchase Common Shares or Debt Securities ("Warrants") which shall be evidenced by warrant certificates that the Company may issue under one or more warrant indentures between the Company and a warrant trustee for the holders of the Warrants, or without any warrant indenture, (iv) subscription receipts for Common Shares, Debt Securities, Warrants or any combination thereof ("Subscription Receipts") which may be issued under one or more subscription receipt agreements between the Company and an escrow agent, or (v) any combination of Common Shares, Debt Securities, Warrants or Subscription Receipts ("Units") (collectively, the Common Shares, Debt Securities, Warrants, Subscription Receipts and Units are referred to as the "Securities"). The Securities will be offered in amounts, at prices and on terms to be determined in light of market conditions at the time of sale and to be set forth in supplements (each a "Prospectus Supplement") to the prospectus contained in the Registration Statement.

In connection with this opinion letter, we have examined the Company's Articles of Incorporation (the "Articles of Incorporation") and the Bylaws (the "Bylaws", and together with the Articles of Incorporation, the "Charter Documents"), each as amended or amended and restated through the date hereof; records of corporate proceedings of the Company with respect to the matters contained in the Registration Statement dated as of February 21, 2020; an executed copy of the Registration Statement; and the proposed form of Indenture, which form is being filed as an exhibit to the Registration Statement. In addition, we have reviewed such questions of New York law as we have considered necessary and appropriate for the purposes of our opinion set forth below.
