Ladies and Gentlemen:

I, Jessica Milner, serve as Deputy General Counsel of UGI Corporation, a Pennsylvania corporation (the “Company”). My opinion has been requested in connection with the Company’s filing, on May 18, 2021, with the Securities and Exchange Commission (the “Commission”) of a prospectus supplement (as amended and supplemented, the “Prospectus Supplement”) pursuant to a registration statement on Form S-3 (File No. 333-256180) (as amended, the “Registration Statement”), including a base prospectus (such base prospectus, together with the Prospectus Supplement, the “Prospectus”), under the Securities Act of 1933, as amended (the “Act”), relating to the registration of certain securities, including up to 2,200,000 equity units of the Company, each initially consisting of a unit referred to as a Corporate Unit (collectively, the “Corporate Units”) consisting of (i) a Common Stock Purchase Contract (each a “Purchase Contract”) to be issued under the Purchase Contract and Pledge Agreement, dated as of May 25, 2021 (the “Purchase Contract Agreement”), by and between the Company and U.S. Bank National Association, as Purchase Contract Agent (in such capacity, the “Purchase Contract Agent”), Collateral Agent, Custodial Agent and Securities Intermediary, and (ii) a 10% undivided beneficial interest in one share of 0.125% Series A Cumulative Perpetual Convertible Preferred Stock, no par value, of the Company (the “Convertible Preferred Stock”). The shares of Convertible Preferred Stock are being issued pursuant to the Certificate of Designations of the Convertible Preferred Stock, as filed by the Company with the Secretary of State of the State of Pennsylvania on May 25, 2021 (the “Convertible Preferred Stock Certificate of Designations”). The Convertible Preferred Stock will be convertible into (i) either (x) shares of 0.125% Series B Cumulative Perpetual Preferred Stock, no par value, of the Company (the “Series B Preferred Stock”) or (y) cash and (ii) in certain circumstances, shares of the Company’s common stock, no par value (the “Common Stock”). The shares of Series B Preferred Stock will be issued pursuant to the Certificate of Designations of the Series B Preferred Stock, as filed by the Company with the Secretary of State of the State of Pennsylvania on May 25, 2021 (the “Series B Preferred Stock Certificate of Designations”). The Corporate Units include the 200,000 Corporate Units that the Underwriters (as defined below) purchased pursuant to the underwriting agreement (the “Underwriting Agreement”), dated as of May 25, 2021, between the Company and the representatives of the underwriters named therein (the “Underwriters”).
