[LETTERHEAD OF WACHTELL, LIPTON, ROSEN & KATZ]

February 6, 2007

U.S. Bancorp 800 Nicollet Mall Minneapolis, Minnesota 55402 Ladies and Gentlemen:

                    We have acted as special counsel to U.S. Bancorp, a Delaware corporation (“Parent”), in connection with (1) the proposed merger (the “First Step Merger”) of Cascade Acquisition Corporation, a Minnesota corporation (“Cascade”) with and into United Financial Corp., a Minnesota corporation (“Company”), pursuant to the Agreement and Plan of Merger (the “Agreement”), dated as of November 6, 2006, by and between Parent, Cascade and Company and (2) the proposed merger, immediately following the First Step Merger, of Company with and into Parent (the “Upstream Merger”), pursuant to the Agreement and Plan of Merger (the “Upstream Merger Agreement”), by and between Company and Parent, dated as of February 6, 2007 (the First Step Merger and the Upstream Merger, taken together, the “Merger”). At your request, and pursuant to Section 6.2(c) of the Agreement, we are rendering our opinion concerning certain federal income tax consequences of the Merger. Any capitalized term used and not defined herein has the meaning given to it in the Agreement.

                    For purposes of the opinion set forth below, we have relied, with the consent of Parent and the consent of Company, upon the accuracy and completeness of the statements and representations (which statements and representations we have neither investigated nor verified) contained, respectively, in certain letters to us from the officers of Parent and Company dated the date hereof, and have assumed that such statements and representations will be true, correct and complete as of the Effective Time (as if made as of such time) and that all such statements and representations made to the knowledge of any person or entity or with similar qualification are and will be true, correct and complete as if made without such qualification. We have also relied upon the accuracy of the Form S-4 filed with the SEC in connection with the Merger (as amended through the date hereof, the “Registration Statement”) and the Proxy Statement contained therein, each as amended or supplemented through the date hereof.

                    We have also assumed that: (i) the transactions contemplated by the Agreement and the Upstream Merger Agreement will be consummated in accordance therewith and as described in the Proxy Statement (and no transaction or condition described therein and affecting this opinion will be waived by any party), (ii) the First Step Merger will qualify as a statutory

merger under the applicable laws of the State of Minnesota and the Upstream Merger will qualify as a statutory merger under the applicable laws of the States of Minnesota and Delaware, and (iii) the Merger will be reported by Parent and Company on their respective federal income tax returns in a manner consistent with the opinion set forth below.

                    Based upon and subject to the foregoing, it is our opinion, under currently applicable U.S. federal income tax law, that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Code.

                    We hereby consent to the filing of this opinion with the SEC as a post-effective amendment to the Registration Statement, and to the references therein to us. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended. This opinion relates solely to certain U.S. federal income tax consequences of the Merger and no opinion is expressed as to the tax consequences under any foreign, state or local tax law or under any federal tax laws other than those pertaining to the income tax. We are furnishing this opinion to you solely in connection with the Merger, and this opinion is not to be relied upon by any other person or for any other purpose.

                                                                     Very truly yours,

                                                                                                                                                                    /s/ Wachtell, Lipton, Rosen & Katz

United Financial Corp.
P.O. Box 2779

Great Falls, Montana 59403

Ladies and Gentlemen:

We have acted as counsel to United Financial Corp., a Minnesota corporation (“Company”) in connection with the proposed merger (the “First Step Merger”) of Cascade Acquisition Corporation, a Minnesota corporation (“Cascade”) with and into the Company pursuant to the Agreement and Plan of Merger (the “Agreement”), dated as of November 6, 2006, by and between U.S. Bancorp, a Delaware corporation (“Parent”), Cascade and Company. At your request, and pursuant to Section 6.3(c) of the Agreement, we are rendering our opinion concerning certain federal income tax consequences of the Merger (as defined below). Any capitalized term used and not defined herein has the meaning given to it in the Agreement.

We have assumed that: (i) immediately following the First Step Merger, the Company will merge with and into the Parent (the “Upstream Merger”) pursuant to the Agreement and Plan of Merger (the “Upstream Merger Agreement”) by and between Company and Parent, dated as of February 6, 2007 (the First Step Merger and the Upstream Merger, taken together, are the “Merger”), (ii) the transactions contemplated by the Agreement and the Upstream Merger Agreement will be consummated in accordance therewith and as described in the Proxy Statement (and no transaction or condition described therein and affecting this opinion will be waived by any party), (iii) the First Step Merger will qualify as a statutory merger under the applicable laws of the State of Minnesota and the Upstream Merger will qualify as a statutory merger under the applicable laws of the State of Minnesota and the State of Delaware, and (iv) the Merger will be reported by Parent and Company on their respective federal income tax returns in a manner consistent with the opinion set forth below.

For purposes of the opinion set forth below, we have relied, with your consent and the consent of Parent, upon the accuracy and completeness of the statements and representations (which statements and representations we have neither investigated nor verified) contained, respectively, in certain letters to us from the officers of Company and Parent dated the date

---

hereof, and have assumed that such statements and representations will be true, correct and complete as of the Effective Time (as if made as of such time) and that all such statements and representations made to the knowledge of any person or entity or with similar qualification are and will be true, correct and complete as if made without such qualification. We have also relied upon the accuracy of the Form S-4 filed with the SEC in connection with the Merger (as amended through the date hereof, the “Registration Statement”) and the Proxy Statement contained therein, each as amended or supplemented through the date hereof.

We also have examined such matters of law, including the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), proposed and finalized Treasury regulations promulgated thereunder, and judicial and administrative decisions, rulings and interpretations thereof currently in effect, as we have deemed appropriate as a basis for our opinion set forth below. Such matters of law are subject to change, possibly with retroactive effect, which change could affect the opinion set forth herein. We have undertaken no obligation to update this letter for events occurring or coming to our attention after the date hereof.

Based upon and subject to the foregoing, and subject to the qualifications set forth herein, it is our opinion, under currently applicable U.S. federal income tax law, that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Code.

We hereby consent to the filing of this opinion with the SEC as a post-effective amendment to the Registration Statement, and to the references therein to us. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended.

This opinion relates solely to certain U.S. federal income tax consequences of the Merger and no opinion is expressed as to the tax consequences under any foreign, state or local tax law or under any federal tax laws other than those pertaining to the income tax. This opinion has no binding effect on the Internal Revenue Service or the courts, and there can be no assurance that a contrary view will not be taken by the Internal Revenue Service or, if contested, by the courts. No ruling from the Internal Revenue Service has been or will be sought on any issues related to the transactions described herein. We are furnishing this opinion to you solely in connection with the Merger, and this opinion is not to be relied upon by any other person or for any other purpose.

Very Truly yours,                                                         LINDQUIST & VENNUM P.L.L.P.                                                         /s/ Lindquist & Vennum P.L.L.P.
