Ladies and Gentlemen:

I have acted as Deputy General Counsel to UnitedHealth Group Incorporated, a Delaware corporation which was a Minnesota corporation prior to its reincorporation in Delaware on July 1, 2015 (the “Company”), in connection with the preparation of its registration statement on Form S-3 (the “Registration Statement”) filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), relating to the proposed public offering of one or more of the following securities of the Company: (i) unsecured debt securities, which may be either senior debt securities or subordinated debt securities (the “Debt Securities”); (ii) shares of preferred stock, par value $0.001 per share (the “Preferred Shares”); (iii) shares of common stock, par value $0.01 per share (the “Common Shares”); (iv) warrants to purchase Debt Securities (the “Debt Warrants”); (v) warrants to purchase Preferred Shares (the “Preferred Stock Warrants”); (vi) warrants to purchase Common Shares (the “Common Stock Warrants”); and (vii) guarantees by the Company, which may be either senior guarantees or subordinated guarantees (the “Guarantees,” and, together with the Debt Securities, the Preferred Shares, the Common Shares, the Debt Warrants, the Preferred Stock Warrants and the Common Stock Warrants, the “Securities”). All of the Securities may be sold from time to time and on a delayed or continuous basis, as set forth in the prospectus which forms a part of the Registration Statement, and as to be set forth in one or more supplements to the prospectus.

I have also assumed that any Debt Securities will be issued pursuant to the indenture dated as of February 4, 2008 between the Company and U.S. Bank Trust Company, National Association, as trustee, filed as Exhibit 4.1 to the Registration Statement and as amended or supplemented from time to time in accordance with its terms (the “Indenture”) and that any Debt Securities will be issued and sold with such terms and in such manner as are described in the Registration Statement (as amended from time to time), the prospectus included therein (as amended from time to time) and any related supplements to the prospectus.
